    Objective To determine the type and frequency of neurological signs and symptoms in individuals with fibromyalgia (FM). Methods Persons with FM (n=166) and pain-free controls (n=66) underwent systematic neurological examination by a neurologist blinded to disease status. Neurological symptoms present over the preceding 3 months were assessed with a standard questionnaire. We used logistic regression to evaluate the association of neurological symptoms and examination findings with FM status. Within the FM group we examined the correlation between self-reported symptoms and physical examination findings. Results Compared to the control group, age and gender adjusted estimates revealed the FM group had significantly more neurological abnormalities in multiple categories including: cranial nerves IX and X (42% vs. 8%), sensory (65% vs. 25%), motor (33% vs. 3%), and gait (28% vs. 7%). Similarly, the FM group endorsed significantly more neurological symptoms than the control group in 27 of 29 categories with the biggest differences observed for photophobia (70% vs. 6%), poor balance (63% vs. 4%), and weakness (58% vs. 2%) and tingling (54% vs. 4%) in the arms and legs. Poor balance, coordination, tingling, weakness in the arms and legs, and numbness in any part of body correlated with appropriate neurological exam findings in the FM group. Conclusions This blinded, controlled study demonstrated neurological physical examination findings in persons with FM. The FM group had more neurological symptoms than controls, with moderate correlation between symptoms and signs. These findings have implications for the medical work-up of patients with FM.

    To determine the type and frequency of neurologic signs and symptoms in individuals with fibromyalgia (FM). Persons with FM (n = 166) and pain-free controls (n = 66) underwent systematic neurologic examination by a neurologist blinded to disease status. Neurologic symptoms lasting at least 3 months were assessed with a standard questionnaire. We used logistic regression to evaluate the association of neurologic symptoms and examination findings with FM status. Within the FM group we examined the correlation between self-reported symptoms and physical examination findings. Age- and sex-adjusted estimates revealed that compared with the control group, the FM group had significantly more neurologic abnormalities in multiple categories, including greater dysfunction in cranial nerves IX and X (42% versus 8%) and more sensory (65% versus 25%), motor (33% versus 3%), and gait (28% versus 7%) abnormalities. Similarly, the FM group had significantly more neurologic symptoms than the control group in 27 of 29 categories, with the greatest differences observed for photophobia (70% versus 6%), poor balance (63% versus 4%), and weakness (58% versus 2%) and tingling (54% versus 4%) in the arms or legs. Poor balance or coordination, tingling or weakness in the arms or legs, and numbness in any part of the body correlated with appropriate neurologic examination findings in the FM group. This blinded, controlled study demonstrated neurologic physical examination findings in persons with FM. The FM group had more neurologic symptoms than did the controls, with moderate correlation between symptoms and signs. These findings have implications for the medical evaluation of patients with FM.

    Prevalence and course of psychogenically influenced symptoms in neurology and their dependence on age and gender are reported. The epidemiological basis of the data is a long-term follow-up investigation of a high-risk population for about 10 years (n = 240): the Mannheim Cohort Study on Epidemiology of Psychogenic Disorders. Seven psychogenic symptoms of neurologic relevance (headache, lumbar and cervical vertebral complaints, functional vertigo, hyperkinesias, pareses, sleep and concentration disturbances) are characterized in regard to frequency, course and diagnostic significance.

    Behavioural and psychiatric symptoms (BPS) are frequent in neurological patients, contribute to disability, and decrease quality of life. We recorded BPS prevalence and type, as well as any associations with specific diagnoses, brain regions, and treatments, in consecutive outpatients examined in a cognitive neurology clinic. A retrospective analysis of 843 consecutive patients was performed, including a review of BPS, diagnosis, sensory impairment, lesion topography (neuroimaging), and treatment. The total sample was considered, and the cognitive impairment (CI) group (n=607) was compared to the non-CI group. BPS was present in 59.9% of the patients (61.3% in the CI group, 56.4% in the non-CI group). One BPS was present in 31.1%, two in 17.4%, and three or more in 11.4%. BPS, especially depression and anxiety, are more frequent in women than in men. Psychotic and behavioural symptoms predominate in subjects aged 65 and older, and anxiety in those younger than 65. Psychotic symptoms appear more often in patients with sensory impairment. Psychotic and behavioural symptoms are more prevalent in patients with degenerative dementia; depression and anxiety in those who suffer a psychiatric disease or adverse effects of substances; emotional lability in individuals with a metabolic or hormonal disorder; hypochondria in those with a pain syndrome; and irritability in subjects with chronic hypoxia. Behavioural symptoms are more frequent in patients with anomalies in the frontal or right temporal or parietal lobes, and antipsychotics constitute the first line of treatment. Leaving standard treatments aside, associations were observed between dysthymia and opioid analgesics, betahistine and statins, and between psychotic symptoms and levodopa, piracetam, and vasodilators.

    Dental assistants help the dentist in preparing material for filling teeth. Amalgam was the filling material mostly commonly used in Norway before 1980, and declined to about 5% of all fillings in 2005. Amalgam is usually an alloy of silver, copper, tin and mercury. Copper amalgam, giving particularly high exposure to mercury was used in Norway until 1994. Metallic mercury is neurotoxic. Few studies of the health of dental assistants exist, despite their exposure to mercury. There are questions about the existence of possible chronic neurological symptoms today within this working group, due to this exposure. The aim of this study was to compare the occurrence of neurological symptoms among dental assistants likely to be exposed to mercury from work with dental filling material, compared to similar health personnel with no such exposure. All dental assistants still at work and born before 1970 registered in the archives of a trade union in Hordaland county of Norway were invited to participate (response rate 68%, n = 41), as well as a similar number of randomly selected assistant nurses (response rate 87%, n = 64) in the same age group. The participants completed a self-administered, mailed questionnaire, with questions about demographic variables, life-style factors, musculoskeletal, neurological and psychosomatic symptoms (Euroquest). The dental assistants reported significant higher occurrence of neurological symptoms; psychosomatic symptoms, problems with memory, concentration, fatigue and sleep disturbance, but not for mood. This was found by analyses of variance, adjusting for age, education, alcohol consumption, smoking and personality traits. For each specific neurological symptom, adjusted logistic regression analyses were performed, showing that these symptoms were mainly from arms, hands, legs and balance organs. There is a possibility that the higher occurrence of neurological symptoms among the dental assistants may be related to their previous work

    Objective: To determine the incidence, timing, and severity of neurologic findings in acute HIV infection (pre–antibody seroconversion), as well as persistence with combination antiretroviral therapy (cART). Methods: Participants identified with acute HIV were enrolled, underwent structured neurologic evaluations, immediately initiated cART, and were followed with neurologic evaluations at 4 and 12 weeks. Concurrent brain MRIs and both viral and inflammatory markers in plasma and CSF were obtained. Results: Median estimated HIV infection duration was 19 days (range 3–56) at study entry for the 139 participants evaluated. Seventy-three participants (53%) experienced one or more neurologic findings in the 12 weeks after diagnosis, with one developing a fulminant neurologic manifestation (Guillain-Barré syndrome). A total of 245 neurologic findings were noted, reflecting cognitive symptoms (33%), motor findings (34%), and neuropathy (11%). Nearly half of the neurologic findings (n = 121, 49%) occurred at diagnosis, prior to cART initiation, and most of these (n = 110, 90%) remitted concurrent with 1 month on treatment. Only 9% of neurologic findings (n = 22) persisted at 24 weeks on cART. Nearly all neurologic findings (n = 236, 96%) were categorized as mild in severity. No structural neuroimaging abnormalities were observed. Participants with neurologic findings had a higher mean plasma log10 HIV RNA at diagnosis compared to those without neurologic findings (5.9 vs 5.4; p = 0.006). Conclusions: Acute HIV infection is commonly associated with mild neurologic findings that largely remit while on treatment, and may be mediated by direct viral factors. Severe neurologic manifestations are infrequent in treated acute HIV. PMID:27287217

    In celiac disease (CD), the gut is the typical manifestation site but atypical neurological presentations are thought to occur in 6 to 10% with cerebellar ataxia being the most frequent symptom. Most studies in this field are focused on patients under primary neurological care. To exclude such an observation bias, patients with biopsy proven celiac disease were screened for neurological disease. A total of 72 patients with biopsy proven celiac disease (CD) (mean age 51 +/- 15 years, mean disease duration 8 +/- 11 years) were recruited through advertisements. All participants adhered to a gluten-free diet. Patients were interviewed following a standard questionnaire and examined clinically for neurological symptoms. Medical history revealed neurological disorders such as migraine (28%), carpal tunnel syndrome (20%), vestibular dysfunction (8%), seizures (6%), and myelitis (3%). Interestingly, 35% of patients with CD reported of a history of psychiatric disease including depression, personality changes, or even psychosis. Physical examination yielded stance and gait problems in about one third of patients that could be attributed to afferent ataxia in 26%, vestibular dysfunction in 6%, and cerebellar ataxia in 6%. Other motor features such as basal ganglia symptoms, pyramidal tract signs, tics, and myoclonus were infrequent. 35% of patients with CD showed deep sensory loss and reduced ankle reflexes in 14%. Gait disturbances in CD do not only result from cerebellar ataxia but also from proprioceptive or vestibular impairment. Neurological problems may even develop despite strict adherence to a gluten-free diet. (c) 2009 Movement Disorder Society.

    We report a 48-year-old Japanese woman with phenylketonuria (PKU) who presented with severe neurological symptoms more than 30 years after discontinuation of dietary treatment. She was diagnosed with PKU at 6-years-old and was treated with a phenylalanine restricted diet until she was 15 years old. When she was 48-years-old she started having difficulty walking. After several months, she presented with severe disturbance of consciousness and was admitted. She was diagnosed as having neurological complications associated with PKU. We observed temporal changes in her laboratory data, brain MRI and single-photon emission computed tomography (SPECT) scan findings. Brain MRI on T2-weighted, fluid-attenuated inversion recovery and diffusion-weighted images revealed high intensity lesions in her bilateral frontal lobes and 123I-IMP SPECT showed marked and diffuse hypoperfusion in the bilateral cerebrum and cerebellum. After the resumption of dietary treatment, serum phenylalanine concentrations immediately decreased to the normal range. However, her neurological symptoms took longer to improve. We also found no clear temporal association between MRI findings and clinical severity. SPECT abnormalities showed marked improvement after treatment. It is well known that PKU patients who discontinue the dietary restriction from their childhood develop minor neurological impairments. However, PKU patients with late-onset severe neurological symptoms are very rare. To our knowledge, this is the first report regarding SPECT findings of PKU patients with late-onset severe neurological deterioration. Copyright © 2015 Elsevier Ltd. All rights reserved.

    The aims of the present study were to assess symptoms associated with an autism spectrum disorder (ASD) in children with neurological disorders as reported by parents and teachers on the Autism Spectrum Screening Questionnaire (ASSQ), as well as the level of agreement between informants for each child. The ASSQ was completed by parents and teachers of the 5781 children (11-13 years) who participated in the second wave of the Bergen Child Study (BCS), an on-going longitudinal population-based study. Out of these children, 496 were reported to have a chronic illness, including 99 whom had a neurological disorder. The neurological disorder group included children both with and without intellectual disabilities. Children with neurological disorders obtained significantly higher parent and teacher reported ASSQ scores than did non-chronically ill children and those with other chronic illnesses (pchildren with neurological disorders was moderate to high for the total score and for three sub scores generated from a factor analysis, and low to moderate for single items. The ASSQ identifies a high rate of ASD symptoms in children with neurological disorders, and a large number of children screened in the positive range for ASD. Although a firm conclusion awaits further clinical studies, the present results suggest that health care professionals should be aware of potential ASD related problems in children with neurological disorders, and should consider inclusion of the ASSQ or similar screening instruments as part of their routine assessment of this group of children.

    Thymolipomas are rare slow-growing mediastinal thymic neoplasms. Most cases are asymptomatic and are sometimes discovered as a huge mass on chest x-ray films. A few cases have been discovered during examinations for other diseases. We report the second case of thymolipoma combined with hyperthyroidism in the English language literature. Neurological symptoms suddenly appeared in a 45-year-old woman. Central nervous system disorder was suggested but no significant abnormalities were found on brain MR nor were there any neurological signs. Several months later, neurological and systemic examinations on admission revealed hyperthyroidism and an anterior mediastinal tumor, 9.0x5.0x3.0 cm in size on chest CT films. Despite treatment of hyperthyroidism by medication, her neurological symptoms remained. Neurologists recommended resection of the mediastinal tumor. Malignancy could not be ruled out because of the irregularity of the tumor appearance on contrast-enhanced chest CT. Furthermore, the tumor appeared to be attached to the ascending aorta, so cytological and/or pathological diagnosis by CT-guided needle biopsy before operation were contraindicated. Extended thymectomy was performed in May 2005. The pathological diagnosis was benign thymolipoma consisting of mature fatty tissue and thymic tissue structures with Hassall's corpuscles. Her neurological symptoms seemed slightly but not markedly improved. The relationship between thymolipoma and hyperthyroidism is still unknown.

  13. Obsessive–Compulsive Symptoms in Neurologic Disease: A Review

    1992-01-01

    Full Text Available Obsessive–compulsive disorder (OCD is an increasingly recognized disorder with a prevalence of 2–3% (Robins et al., 1984. Once thought to be psychodynamic in origin, OCD is now generally recognized as having a neurobiological cause. Although the exact pathophysiology of OCD in its pure form remains unknown, there are numerous reports of obsessive–compulsive symptoms arising in the setting of known neurological disease. In this paper, we review the reported cases of obsessive–compulsive symptoms associated with neurologic diseases and outline the known facts about the underlying neurobiology of OCD. Finally, we synthesize these findings into a proposed theory of the pathophysiology of OCD, in both its pure form and when it accompanies other neurological illness.

    The lack of neurologic symptoms is rare in herpes simplex encephalitis (HSE). A 42-year-old woman presented with psychiatric features alone, such as Korsakoff syndrome and abortive type Kluver-Bucy syndrome. The diagnosis of HSE was confirmed by serologically elevated antibody titer. The patient underwent both X-ray computed tomography and magnetic resonance imaging (MRI). X-ray computed tomography showed transient contrast enhancement and low density area confined to the lateral lobe. Magnetic resonance imaging revealed diffuse areas with a high MRI signal intensity. Considering that the lack of neurologic features, as seen in the present HSE patient, may sometimes rule out the possibility of parenchymal disease, imaging modalities, especially MRI, may be of value in the detection of lesions for HSE.

    Analysis of cerebrospinal fluid is required in order to diagnose Lyme neuroborreliosis. We investigated the symptoms of patients in a highly endemic area who were referred for evaluation of possible Lyme neuroborreliosis, and explored whether cerebrospinal fluid analysis confirmed or ruled out the diagnosis. We reviewed the medical records of all patients who underwent lumbar puncture at Sørlandet Hospital Arendal in the period 1 January 2013 to 31 December 2013. A total of 140 patients were referred with suspected Lyme neuroborreliosis. Of these, 110 patients had non-specific neurological symptoms (e.g. fatigue, dizziness and headache), only one of whom received a diagnosis of possible Lyme neuroborreliosis. Thirty patients had symptoms typical of the condition (such as radiculitis or peripheral facial nerve palsy). Six of these were diagnosed with definite Lyme neuroborreliosis, and one with possible Lyme neuroborreliosis. None of those diagnosed with Lyme neuroborreliosis had had symptoms lasting more than six months. The probability of Lyme neuroborreliosis is low in the absence of typical symptoms of the condition, even when anti-Borrelia antibodies are detected in serum and especially when the symptoms are of long duration.

    Symptoms, diagnosis and therapy of equine botulism are discussed by the presentation of two detailed reports of horses with neurological symptoms and the results of laboratory investigations over the period 2003-2008 in the Netherlands. In addition a brief summary of the available literature is presented. Prevailing symptoms of botulism in horses include paralysis of the tongue, salvation, dysphagia and paresis and paralysis of the skeletal muscles, as well as signs of colic. Symptoms and prognosis vary with the amount of botulinum neurotoxin (BoNT) involved. For early clinical diagnosis of botulism thorough investigation of the facial nerves is important, for instance by the use of the 'Tongue Stress Test'. Laboratory results often remain negative, probably due to the sampling time, the high sensitivity of horses for botulinum neurotoxin or treatment with antitoxins. Most clinical cases in horses are caused by botulinum neurotoxin B (BoNT/B). For therapy to be successful antiserum needs to be administered in the earliest possible stage of the disease and this should be supported by symptomatic therapy. Botulism is a feed-related intoxication caused by either carcasses in the roughage or BoNT/B production after poor conservation of grass silage. This is the main source of botulism in horses due to the popularity of individually packed grass silage as feed for horses. As long as no vaccine is available in the Netherlands quality control of silage and haylage is strictly recommended in order to reduce the risk of botulism in horses.

    Full Text Available Environmental exposures of workplace may affect employees' health including the nervous and psychological systems. Aim of this study was to determine the effects of occupational factors on psychological and neurological systems in workplaces. This is historical cohort study on employees in low and high exposure groups. The study's tool was flexible interview, questionnaire and occupational factors measurement. Sick employees were followed until the end of treatment. Headache was higher in employees with high level of lighting. The relative risk was 1.45 (1.04-2.02. Dizziness was significantly more in the working hours in offices. The risk ratio for dizziness was 2.25 (1.80-2.33. Employees with high exposure to occupational factors were at higher risk for headache and dizziness. There is relationship between loss of concentration and age. The risk ratio was 1.63 (1.13-2.36. The results of this study indicated that people who exposed to occupational and environmental pollutants occupational might be a risk for some psychological and neurological symptoms such as headache and dizziness and impaired concentration would be increased by aging.

    Conclusions: Our findings add to a growing literature indicating that a baseline state of high arousal may be a precondition for generating functional neurological symptoms, a finding that helps explain why a range of psychological and physiological stressors can trigger functional neurological symptoms in some patients. Interventions that target cortical arousal may be central to the treatment of paediatric patients with functional neurological symptom disorder.

    Thallium (Tl + ) is a ubiquitous natural trace metal considered as the most toxic among heavy metals. The ionic ratio of Tl + is similar to that of potassium (K + ), therefore accounting for the replacement of the latter during enzymatic reactions. The principal organelle damaged after Tl + exposure is mitochondria. Studies on the mechanisms of Tl + include intrinsic pathways altered and changes in antiapoptotic and proapoptotic proteins, cytochrome c, and caspases. Oxidative damage pathways increase after Tl + exposure to produce reactive oxygen species (ROS), changes in physical properties of the cell membrane caused by lipid peroxidation, and concomitant activation of antioxidant mechanisms. These processes are likely to account for the neurotoxic effects of the metal. In humans, Tl + is absorbed through the skin and mucous membranes and then is widely distributed throughout the body to be accumulated in bones, renal medulla, liver, and the Central Nervous System. Given the growing relevance of Tl + intoxication, in recent years there is a notorious increase in the number of reports attending Tl + pollution in different countries. In this sense, the neurological symptoms produced by Tl + and its neurotoxic effects are gaining attention as they represent a serious health problem all over the world. Through this review, we present an update to general information about Tl + toxicity, making emphasis on some recent data about Tl + neurotoxicity, as a field requiring attention at the clinical and preclinical levels.

    Though yoga is one of the widely used mind-body medicine for health promotion, disease prevention and as a possible treatment modality for neurological disorders, there is a lack of evidence-based review. Hence, we performed a comprehensive search in the PubMed/Medline electronic database to review relevant articles in English, using keywords "yoga and neurological disorder, yoga and multiple sclerosis, yoga and stroke, yoga and epilepsy, yoga and Parkinson's disease, yoga and dementia, yoga and cerebrovascular disease, yoga and Alzheimer disease, yoga and neuropathy, yoga and myelopathy, and yoga and Guillain-Barre syndrome". A total of 700 articles published from 1963 to 14th December 2016 were available. Of 700 articles, 94 articles were included in this review. Based on the available literature, it could be concluded that yoga might be considered as an effective adjuvant for the patients with various neurological disorders. Copyright © 2017 Elsevier Ltd.

    We discussed the relationship between neurological symptoms and the locations of syringes observed by CT and MRI (imaging diagnosis) in six cases of syringomyelia admitted to our department during the past five years. Neurological symptoms of the upper cervical and thoracic cords were found in six cases and five cases of them had symmetric distribution. Syringes were found in all cases by delayed CT (D-CT) and MRI. Five cases had laterality. The sites in the spinal cord exhibiting severe involvement of neurological symptoms corresponded with the sites of syringes in imaging diagnosis. The main asymmetric lesions of the syringes were located in the posterior horn. They indicated the relationship with the appearance of the neurological symptoms of the lesion. We compared with the width of the longitudinal level from neurological findings and imaging diagnosis. The rostral level of both corresponded in all cases, but the caudal level corresponded in only one case and neurological symptoms were broader than syringes in imaging diagnosis. It was difficult to identify small syringes when there was complicated scoliosis. The diagnosis of typical cases of syringomyelia is mainly based on such neurological symptoms as a bilateral segmental pattern of dissociated sensory impairment in the past, but imaging diagnosis has recently come to be regarded as very important.

    It is becoming increasingly more important to study, use, and promote the utility of measures that are designed to detect non-compliance with testing (i.e., poor effort, symptom non-validity, response bias) as part of neuropsychological assessments with children and adolescents. Several measures have evidence for use in pediatrics, but there is a paucity of published support for the Victoria Symptom Validity Test (VSVT) in this population. The purpose of this study was to examine the performance on the VSVT in a sample of pediatric patients with known neurological disorders. The sample consisted of 100 consecutively referred children and adolescents between the ages of 6 and 19 years (mean = 14.0, SD = 3.1) with various neurological diagnoses. On the VSVT total items, 95% of the sample had performance in the "valid" range, with 5% being deemed "questionable" and 0% deemed "invalid". On easy items, 97% were "valid", 2% were "questionable", and 1% was "invalid." For difficult items, 84% were "valid," 16% were "questionable," and 0% was "invalid." For those patients given two effort measures (i.e., VSVT and Test of Memory Malingering; n = 65), none was identified as having poor test-taking compliance on both measures. VSVT scores were significantly correlated with age, intelligence, processing speed, and functional ratings of daily abilities (attention, executive functioning, and adaptive functioning), but not objective performance on the measure of sustained attention, verbal memory, or visual memory. The VSVT has potential to be used in neuropsychological assessments with pediatric patients.

    The name given to functional neurologic symptoms has evolved over time in the different editions of the International Classification of Diseases (ICD) and the Diagnostic and Statistical Manual of Mental Disorders (DSM), reflecting a gradual move away from an etiologic conception rooted in hysterical conversion to an empiric phenomenologic one, emphasizing the central role of the neurologic examination and testing in demonstrating that the symptoms are incompatible with recognized neurologic disease pathophysiology, or are internally inconsistent. © 2016 Elsevier B.V.

    Full Text Available Abstract Background Food insecurity (FI has been shown to be associated with poor health both in developing and developed countries. Little is known about the relation between FI and neurological disorder. We assessed the relation between FI and risk for neurologic symptoms in southwest Ethiopia. Methods Data about food security, gender, age, household assets, and self-reported neurologic symptoms were collected from a representative, community-based sample of adults (N = 900 in Jimma Zone, Ethiopia. We calculated univariate statistics and used bivariate chi-square tests and multivariate logistic regression models to assess the relation between FI and risk of neurologic symptoms including seizures, extremity weakness, extremity numbness, tremors/ataxia, aphasia, carpal tunnel syndrome, vision dysfunction, and spinal pain. Results In separate multivariate models by outcome and gender, adjusting for age and household socioeconomic status, severe FI was associated with higher odds of seizures, movement abnormalities, carpal tunnel, vision dysfunction, spinal pain, and comorbid disorders among women. Severe FI was associated with higher odds of seizures, extremity numbness, movement abnormalities, difficulty speaking, carpal tunnel, vision dysfunction, and comorbid disorders among men. Conclusion We found that FI was associated with symptoms of neurologic disorder. Given the cross-sectional nature of our study, the directionality of these associations is unclear. Future research should assess causal mechanisms relating FI to neurologic symptoms in sub-Saharan Africa.

    Functional neurological symptom disorders are frequently the basis for acute neurological consultation. In children, they are often precipitated by high-frequency everyday stressors. The extent to which a severe traumatic experience may also precipitate functional neurological abnormalities is unknown. For the 2-week period after the Boston Marathon bombings, we prospectively collected data on patients whose presentation suggested a functional neurological symptom disorder. We assessed clinical and demographic variables, duration of symptoms, extent of educational impact, and degree of connection to the Marathon bombing. We contacted all patients at 6 months after presentation to determine the outcome and accuracy of the diagnosis. In a parallel study, we reported a baseline of 2.6 functional neurological presentations per week in our emergency room. In the week after the Marathon bombings, this frequency tripled. Ninety-one percent of presentations were delayed by 1 week, with onset around the first school day after a city-wide lockdown. Seventy-three percent had a history of a prior psychiatric diagnosis. At the 6 months follow-up, no functional neurological symptom disorder diagnoses were overturned and no new organic diagnosis was made. Pediatric functional neurological symptom disorder may be precipitated by both casual and high-intensity stressors. The 3.4-fold increase in incidence after the Boston Marathon bombings and city-wide lockdown demonstrates the marked effect that a community-wide tragedy can have on the mental health of children. Care providers must be aware of functional neurological symptom disorders after stressful community events in vulnerable patient populations, particularly those with prior psychiatric diagnoses.

    2012-11-01

    Cerebral arterial gas embolism (CAGE) is well known as a complication of invasive medical procedures and as a risk in diving and submarine escape. In the underwater environment, CAGE is caused by trapped air, which expands and leads to lung vessel rupture when ambient pressure decreases during ascent. Pressure decrease also occurs during hypobaric activities such as flying and, therefore, CAGE may theoretically be a risk in hypobaric exposure. We reviewed the available literature on this subject. Identified were 12 cases of CAGE due to hypobaric exposure. Based on these cases, we discuss pathophysiology, diagnosis, and treatment of CAGE due to hypobaric exposure. The low and slow pressure decrease during most hypobaric activities (as opposed to diving) account for the low incidence of CAGE during these exposures and suggest that severe air trapping must be present to cause barotrauma. This is also suggested by the large prevalence of air filled cysts in the case reports reviewed. We recommend considering CAGE in all patients presenting with acute central neurological injury during or shortly after pressure decrease such as flying. A CT scan of head and chest should be performed in these patients. Treatment with hyperbaric oxygen therapy should be initiated as soon as possible in cases of proven or probable CAGE.

    Full Text Available Background: The way the municipal transport drivers perform their job contributes to varied burdens linked with the body posture at work, stress, shift work, vibration, noise and exposure to chemical agents. The aim of the study was to assess the condition of the nervous system (NS in municipal transport drivers. Material and Methods: The study covered 42 men, aged 43.4 years (standard deviation (SD: 8.3, employed as bus drivers in the municipal transport enterprise. The duration of employment was 11.8 years on average (SD: 8.6. The condition of the nervous system was assessed on the basis of clinical neurological examinations. Results: Chronic lumbosacral syndrome was found in 54.8% of the subjects. A significant relationship between the incidence of lumbosacral syndrome and the duration of employment (p = 0.032 was observed; significantly higher in drivers employed for 11–15 years (90.9% in comparison to the remaining groups. Nervous system functional disorders were niejedcharacterized by the increased emotional irritability (47.6%, sleep disorders manifested by excessive sleepiness (33.3% or insomnia (28.6% and headaches (3%, mostly tension headaches. Excessive daytime sleepiness was significantly age-dependent (p = 0.038. Conclusions: The evidenced NS disorders indicate the need to undertake preventive measures tailored for the occupational group of bus drivers. Med Pr 2015;66(3:333–341

    Depression in the elderly is common and often resistant to treatment. It has been suggested that late-life depression may be related to underlying neurobiological changes. However, these observations are derived from diverse clinical samples and as yet have not been confirmed in a more representative population study. Our aim was to investigate associations between neurological signs as markers of underlying brain dysfunction and caseness for depression in an elderly community sample, controlling for physical health and comorbid/past neurological disorders. A cross-sectional analysis of 2102 older people without dementia from the ESPRIT project. Depressive symptomatology was ascertained using the CES-D and abnormal neurological signs/comorbidity from a full neurological examination according to ICD-10 criteria. Pyramidal, extrapyramidal, cranial nerve and sensory deficit signs were significantly associated with case-level depressive symptoms. However, all odds ratios were close to null values in participants who did not have previous neurological disorder. We confirmed previous findings of an association between neurological signs and case-level depressive symptoms in late life. However, this association may simply reflect the impact of more severe comorbid neurological disorder. (c) 2009 John Wiley & Sons, Ltd.

    Full Text Available Pseudobulbar affect (PBA is a neurological condition characterized by involuntary, sudden, and frequent episodes of laughing and/or crying, which can be socially disabling. Although PBA occurs secondary to many neurological conditions, with an estimated United States (US prevalence of up to 2 million persons, it is thought to be under-recognized and undertreated. The PBA Registry Series (PRISM was established to provide additional PBA symptom prevalence data in a large, representative US sample of patients with neurological conditions known to be associated with PBA.Participating clinicians were asked to enroll ≥20 consenting patients with any of 6 conditions: Alzheimer's disease (AD, amyotrophic lateral sclerosis (ALS, multiple sclerosis (MS, Parkinson's disease (PD, stroke, or traumatic brain injury (TBI. Patients (or their caregivers completed the Center for Neurologic Study-Lability Scale (CNS-LS and an 11-point scale measuring impact of the neurological condition on the patient's quality of life (QOL. Presence of PBA symptoms was defined as a CNS-LS score ≥13. Demographic data and current use of antidepressant or antipsychotic medications were also recorded.PRISM enrolled 5290 patients. More than one third of patients (n = 1944; 36.7% had a CNS-LS score ≥13, suggesting PBA symptoms. The mean (SD score measuring impact of neurological condition on QOL was significantly higher (worse in patients with CNS-LS ≥13 vs <13 (6.7 [2.5] vs. 4.7 [3.1], respectively; P<0.0001 two-sample t-test. A greater percentage of patients with CNS-LS ≥13 versus <13 were using antidepressant/antipsychotic medications (53.0% vs 35.4%, respectively; P<0.0001, chi-square test.Data from PRISM, the largest clinic-based study to assess PBA symptom prevalence, showed that PBA symptoms were common among patients with diverse neurological conditions. Higher CNS-LS scores were associated with impaired QOL and greater use of antipsychotic

    We investigated the diagnostic usefulness of brain magnetic resonance imaging (MRI) screening in HIV-1-infected patients without neurological symptoms in detecting intracranial diseases at early stages. In this retrospective analysis, the study patients were HIV-1-infected patients who underwent brain MRI scan in clinical practice between 2001 and 2013. We excluded patients with MRI for (1) follow-up examination for prediagnosed intracranial diseases, (2) cancer staging, (3) screening mycobacterium/bacteria/fungi disease proliferation in the brain, and (4) evaluation for meningitis/encephalitis. The study patients (n=485) were classified into two groups: those who underwent brain MRI scan without any neurological symptoms/signs (asymptomatic patients, n=158) and those who underwent MRI due to such symptoms (symptomatic patients, n=327). Asymptomatic patients had lower CD4 counts than symptomatic patients (median 78 versus 241/μl). Intracranial diseases were detected in three (2%) of the asymptomatic patients [two toxoplasmosis and one progressive multifocal leukoencephalopathy (PML)] compared to 58 (19%) of the symptomatic patients (the χ(2) test, pHIV-associated dementia (n=17). Among symptomatic patients, intracranial diseases were common in those with slurred speech (3/6, 50%), seizure (4/10, 40%), eyesight/vision abnormality (5/16, 31%), altered mental status (8/31, 26%), and hemiplegia/numbness (13/50, 26%). For patients with CD4 count HIV-1-infected patients without neurological symptoms is of little value.

    In this case study, we present two Holocaust survivors who appeared to have adapted well post-trauma, but developed severe PTSD symptomatology following the onset of neurologic illness in later life. These individuals were referred fro neuropsychological evaluations by their treating neurologists to assess their levels of cognitive functioning. We present the neuropsychological findings, and discuss possible mechanisms for emergence of PTSD symptoms. These case studies demonstrate the need for systematic research to further investigate the potential relationship between aging, degenerative disease, and PTSD symptoms in elderly trauma survivors.

    Functional neurological symptom disorder refers to the presence of neurological symptoms not explained by neurological disease. Although this disorder is presumed to reflect abnormal function of the brain, recent studies in adults show neuroanatomical abnormalities in brain structure . These structural brain abnormalities have been presumed to reflect long-term adaptations to the disorder, and it is unknown whether child and adolescent patients, with illness that is typically of shorter duration, show similar deficits or have normal brain structure. High-resolution, three-dimensional T1-weighted magnetic resonance images (MRIs) were acquired in 25 patients (aged 10-18 years) and 24 healthy controls. Structure was quantified in terms of grey matter volume using voxel-based morphometry. Post hoc, we examined whether regions of structural difference related to a measure of motor readiness to emotional signals and to clinical measures of illness duration, illness severity, and anxiety/depression. Patients showed greater volumes in the left supplementary motor area (SMA) and right superior temporal gyrus (STG) and dorsomedial prefrontal cortex (DMPFC) (corrected p disorder.

    The lack of neurologic symptoms is rare in herpes simplex encephalitis (HSE). A 42-year-old woman presented with psychiatric features alone, such as Korsakoff syndrome and abortive type Kluver-Bucy syndrome. The diagnosis of HSE was confirmed by serologically elevated antibody titer. The patient underwent both X-ray computed tomography and magnetic resonance imaging (MRI). X-ray computed tomography showed transient contrast enhancement and low density area confined to the lateral lobe. Magnetic resonance imaging revealed diffuse areas with a high MRI signal intensity. Considering that the lack of neurologic features, as seen in the present HSE patient, may sometimes rule out the possibility of parenchymal disease, imaging modalities, especially MRI, may be of value in the detection of lesions for HSE.

  4. Functional neurological symptom disorder (conversion disorder): A role for microglial-based plasticity mechanisms?

    Science.gov (United States)

    Stephenson, Chris P; Baguley, Ian J

    2018-02-01

    Functional Neurological Symptom Disorder (FND) is a relatively common neurological condition, accounting for approximately 3-6% of neurologist referrals. FND is considered a transient disorder of neuronal function, sometimes linked to physical trauma and psychological stress. Despite this, chronic disability is common, for example, around 40% of adults with motor FND have permanent disability. Building on current theoretical models, this paper proposes that microglial dysfunction could perpetuate functional changes within acute motor FND, thus providing a pathophysiological mechanism underlying the chronic stage of the motor FND phenotypes seen clinically. Core to our argument is microglia's dual role in modulating neuroimmunity and their control of synaptic plasticity, which places them at a pathophysiological nexus wherein coincident physical trauma and psychological stress could cause long-term change in neuronal networks without producing macroscopic structural abnormality. This model proposes a range of hypotheses that are testable with current technologies. Copyright © 2017. Published by Elsevier Ltd.

    Abstract Age-associated neurodegenerative diseases, such as Alzheimer’s disease, Parkinson’s disease, and the polyglutamine (polyQ) diseases, are becoming prevalent as a consequence of elongation of the human lifespan. Although various rodent models have been developed to study and overcome these diseases, they have limitations in their translational research utility owing to differences from humans in brain structure and function and in drug metabolism. Here, we generated a transgenic marmoset model of the polyQ diseases, showing progressive neurological symptoms including motor impairment. Seven transgenic marmosets were produced by lentiviral introduction of the human ataxin 3 gene with 120 CAG repeats encoding an expanded polyQ stretch. Although all offspring showed no neurological symptoms at birth, three marmosets with higher transgene expression developed neurological symptoms of varying degrees at 3–4 months after birth, followed by gradual decreases in body weight gain, spontaneous activity, and grip strength, indicating time-dependent disease progression. Pathological examinations revealed neurodegeneration and intranuclear polyQ protein inclusions accompanied by gliosis, which recapitulate the neuropathological features of polyQ disease patients. Consistent with neuronal loss in the cerebellum, brain MRI analyses in one living symptomatic marmoset detected enlargement of the fourth ventricle, which suggests cerebellar atrophy. Notably, successful germline transgene transmission was confirmed in the second-generation offspring derived from the symptomatic transgenic marmoset gamete. Because the accumulation of abnormal proteins is a shared pathomechanism among various neurodegenerative diseases, we suggest that this new marmoset model will contribute toward elucidating the pathomechanisms of and developing clinically applicable therapies for neurodegenerative diseases.

    The purpose of this study is to evaluate the association between pesticides and neurological symptoms among a population exposed to organophosphate chemicals as a result of agricultural use. Chronic squealed of acute pesticide poisoning from organophosphate compounds include a variety of neurological symptoms including restlessness, irritability, and trouble sleeping. Individuals who have had an acute pesticide poisoning have been reported to suffer a wide range of neurological symptoms that occur from weeks to months after the initial episode. Data for this study came from a cross-sectional survey of farmers and their spouses conducted in an eight-county area in northeastern Colorado. Neurological characteristics were assessed to determine their relationship with previously reported pesticide-related illnesses. Symptoms that were significantly associated with previous poisoning were difficulty concentrating [OR 2.07, 95% confidence interval (CI) 1.22, 3.50]; relatives noticing person had trouble remembering things (OR 2.54, 95% CI 1.47, 4.39); making notes to remember things (OR .18, 95% CI 1.20, 3.97); finding it hard to understand the meaning of newspapers, magazines, and books (OR 1.90, 95% CI 1.01, 3.60); felt irritable OR 1.84, 95% CI 1.08, 3.12); felt depressed (OR 2.82, 95% CI 1.65, 4.81); ad heart palpitations without exertion (OR 2.83, 95% CI 1.22, 6.54); sleeping more than usual (OR 3.58, 95% CI 1.95, 6.58); difficulty moving fingers or grasping things (OR 2.08, 95% CI 1.06, 3.24); and headaches at least once a week (OR 1.85, 95% CI 1.06, 3.24). Stepwise regression was used o identify the best explanatory model of pesticide-related illness. Variables that were associated with increased odds of illness were being ale, being depressed, sleeping too much, and using crop organophosphates

    Full Text Available Abstract A population of patients with unexplained neurological symptoms from six major French university hospitals was screened over a 28-month period for primary creatine disorder (PCD. Urine guanidinoacetate (GAA and creatine:creatinine ratios were measured in a cohort of 6,353 subjects to identify PCD patients and compile their clinical, 1H-MRS, biochemical and molecular data. Six GAMT [N-guanidinoacetatemethyltransferase (EC 2.1.1.2] and 10 X-linked creatine transporter (SLC6A8 but no AGAT (GATM [L-arginine/glycine amidinotransferase (EC 2.1.4.1] deficient patients were identified in this manner. Three additional affected sibs were further identified after familial inquiry (1 brother with GAMT deficiency and 2 brothers with SLC6A8 deficiency in two different families. The prevalence of PCD in this population was 0.25% (0.09% and 0.16% for GAMT and SLC6A8 deficiencies, respectively. Seven new PCD-causing mutations were discovered (2 nonsense [c.577C > T and c.289C > T] and 1 splicing [c.391 + 15G > T] mutations for the GAMT gene and, 2 missense [c.1208C > A and c.926C > A], 1 frameshift [c.930delG] and 1 splicing [c.1393-1G > A] mutations for the SLC6A8 gene. No hot spot mutations were observed in these genes, as all the mutations were distributed throughout the entire gene sequences and were essentially patient/family specific. Approximately one fifth of the mutations of SLC6A8, but not GAMT, were attributed to neo-mutation, germinal or somatic mosaicism events. The only SLC6A8-deficient female patient in our series presented with the severe phenotype usually characterizing affected male patients, an observation in agreement with recent evidence that is in support of the fact that this X-linked disorder might be more frequent than expected in the female population with intellectual disability.

    A population of patients with unexplained neurological symptoms from six major French university hospitals was screened over a 28-month period for primary creatine disorder (PCD). Urine guanidinoacetate (GAA) and creatine:creatinine ratios were measured in a cohort of 6,353 subjects to identify PCD patients and compile their clinical, 1H-MRS, biochemical and molecular data. Six GAMT [N-guanidinoacetatemethyltransferase (EC 2.1.1.2)] and 10 X-linked creatine transporter (SLC6A8) but no AGAT (GATM) [L-arginine/glycine amidinotransferase (EC 2.1.4.1)] deficient patients were identified in this manner. Three additional affected sibs were further identified after familial inquiry (1 brother with GAMT deficiency and 2 brothers with SLC6A8 deficiency in two different families). The prevalence of PCD in this population was 0.25% (0.09% and 0.16% for GAMT and SLC6A8 deficiencies, respectively). Seven new PCD-causing mutations were discovered (2 nonsense [c.577C > T and c.289C > T] and 1 splicing [c.391 + 15G > T] mutations for the GAMT gene and, 2 missense [c.1208C > A and c.926C > A], 1 frameshift [c.930delG] and 1 splicing [c.1393-1G > A] mutations for the SLC6A8 gene).

    Patients with cervical compression myelopathy (CCM) generally present bilateral neurological symptoms in their extremities. However, a substantial portion of patients with CCM exhibit laterality of neurological symptoms. The aim of this study was to assess the correlation between intrinsic structural damage and laterality of symptoms using spinal cord diffusion tensor imaging (DTI) of the corticospinal tract. We enrolled 10 healthy volunteers and 40 patients with CCM in this study. We evaluated motor function using the American Spinal Injury Association (ASIA) motor score for left and right extremities. For DTI acquisitions, a 3.0-T magnetic resonance imaging system with diffusion-weighted spin-echo sequence was used. Regions-of-interest in the lateral column tracts were determined. We determined the correlations between fractional anisotropy (FA) and ASIA motor scores. An FA asymmetry index was calculated using left and right regions-of-interest. Four patients exhibited laterality of symptoms in their extremities, for which left and right ASIA scores correlated moderately with FA in the left and right lateral columns, respectively (left: ρ = 0.64, P laterality of symptoms. Using tract-specific DTI, we demonstrated that microstructural damages in the left and right corticospinal tracts correlated with corresponding neurological symptoms in the ipsilateral side and the FA asymmetry index could indicate laterality in neurological symptoms of patients with CCM.

    Rod migration into the spinal canal after posterior instrumented fusion is a rare complication causing late-onset neurological symptoms. The purpose of the present study is to report a case of a 13-year-old boy with spastic cerebral palsy and related neuromuscular kyphoscoliosis who developed late-onset neurological deterioration secondary to progressive implant migration into the spinal canal over a 5-year period. A decision was made to remove both rods to achieve decompression. Intraoperative findings were consistent with information gained from preoperative imaging. The rods were found to have an intracanal trajectory at T9-T10 for the right rod and T12-L2 for the left rod. The cause of implant migration, with progressive laminar erosion slow enough to generate a solid mass behind, was progressive kyphosis in a skeletally immature patient with neuromuscular compromise. Fixation type, early surgery, and spasticity management contributed significantly to the presenting condition. Mechanical factors and timing of surgery played a decisive role in this particular presentation. Level IV--Case report and review of the literature.

  11. Purinergic Receptors in Neurological Diseases With Motor Symptoms: Targets for Therapy

    Full Text Available Since proving adenosine triphosphate (ATP functions as a neurotransmitter in neuron/glia interactions, the purinergic system has been more intensely studied within the scope of the central nervous system. In neurological disorders with associated motor symptoms, including Parkinson's disease (PD, motor neuron diseases (MND, multiple sclerosis (MS, amyotrophic lateral sclerosis (ALS, Huntington's Disease (HD, restless leg syndrome (RLS, and ataxias, alterations in purinergic receptor expression and activity have been noted, indicating a potential role for this system in disease etiology and progression. In neurodegenerative conditions, neural cell death provokes extensive ATP release and alters calcium signaling through purinergic receptor modulation. Consequently, neuroinflammatory responses, excitotoxicity and apoptosis are directly or indirectly induced. This review analyzes currently available data, which suggests involvement of the purinergic system in neuro-associated motor dysfunctions and underlying mechanisms. Possible targets for pharmacological interventions are also discussed.

  12. Conversion Disorder, Functional Neurological Symptom Disorder, and Chronic Pain: Comorbidity, Assessment, and Treatment.

    This paper examines the overlap of conversion disorder with chronic pain conditions, describes ways to assess for conversion disorder, and provides an overview of evidence-based treatments for conversion disorder and chronic pain, with a focus on conversion symptoms. Conversion disorder is a significant problem that warrants further study, given that there are not many well-established guidelines. Accurate and timely assessment should help move treatment in a more fruitful direction and avoid unnecessary medical interventions. Advances in neuroimaging may also help further our understanding of conversion disorder. Creating a supportive environment and a collaborative treatment relationship and improving understanding of conversion symptoms appear to help individuals diagnosed with conversion disorder engage in appropriate treatments. Novel uses of earlier treatments, such as hypnosis and psychodynamic approaches, could potentially be beneficial and require a more vigorous and systematic study. There are treatments that produce significant improvements in functioning and reduction of physical symptoms from conversion disorder even for very severe cases. Hypnotherapy, cognitive behavioral therapy, and inpatient multidisciplinary treatment with intensive physiotherapy for severe cases have the most evidence to support reduction of symptoms. Components of treatment for conversion disorder overlap with treatments for chronic pain and can be used together to produce therapeutic effects for both conditions. Treatment needs to be tailored for each individual's specific symptoms.

    Within somatization, unexplained neurological symptoms (UNSs) have been shown to mark a distinct subgroup with greater clinical severity. However, some UNSs resemble ataque de nervios somatic symptoms. This raises questions about cultural factors related to Hispanics with somatization characterized by UNSs. To examine cultural factors, preliminary analyses examined the relationship between Hispanic ethnicity, UNSs, and ataque de nervios. Data were obtained from 127 primary care patients (95 Hispanic, 32 European American) with somatization. The Composite International Diagnostic Interview provided somatization data, whereas the Primary Care Evaluation of Mental Disorders was used for data on Axis I disorders. Ataque de nervios was assessed via a proxy measure. Within each ethnic group, cross-tabs examined the relationship between ataque de nervios and multiple UNSs, and ataque de nervios and selected Axis I disorders. Only among Hispanics, a significant overlap was found between ataque de nervios and having four or more UNSs (p nervios and a diagnosis of panic disorder (p = .05). Although equal percentages of European Americans and Hispanics experience multiple UNSs, these results show that the presentation of UNSs among some Hispanics may be qualitatively different, because it may involve features related to ataque de nervios. A diagnosis of panic disorder also appears to interact with cultural factors.

    There is increasing evidence from response time experiments that language statistics and perceptual simulations both play a role in conceptual processing. In an EEG experiment we compared neural activity in cortical regions commonly associated with linguistic processing and visual perceptual processing to determine to what extent symbolic and embodied accounts of cognition applied. Participants were asked to determine the semantic relationship of word pairs (e.g., sky - ground) or to determine their iconic relationship (i.e., if the presentation of the pair matched their expected physical relationship). A linguistic bias was found toward the semantic judgment task and a perceptual bias was found toward the iconicity judgment task. More importantly, conceptual processing involved activation in brain regions associated with both linguistic and perceptual processes. When comparing the relative activation of linguistic cortical regions with perceptual cortical regions, the effect sizes for linguistic cortical regions were larger than those for the perceptual cortical regions early in a trial with the reverse being true later in a trial. These results map upon findings from other experimental literature and provide further evidence that processing of concept words relies both on language statistics and on perceptual simulations, whereby linguistic processes precede perceptual simulation processes.

    Nonmotor symptoms (sleep dysfunction, sensory symptoms, autonomic dysfunction, mood disorders, and cognitive abnormalities) in Parkinson disease (PD) are a major cause of morbidity, yet are often underrecognized. This evidence-based practice parameter evaluates treatment options for the nonmotor symptoms of PD. Articles pertaining to cognitive and mood dysfunction in PD, as well as treatment of sialorrhea with botulinum toxin, were previously reviewed as part of American Academy of Neurology practice parameters and were not included here. A literature search of MEDLINE, EMBASE, and Science Citation Index was performed to identify clinical trials in patients with nonmotor symptoms of PD published between 1966 and August 2008. Articles were classified according to a 4-tiered level of evidence scheme and recommendations were based on the level of evidence. Sildenafil citrate (50 mg) may be considered to treat erectile dysfunction in patients with Parkinson disease (PD) (Level C). Macrogol (polyethylene glycol) may be considered to treat constipation in patients with PD (Level C). The use of levodopa/carbidopa probably decreases the frequency of spontaneous nighttime leg movements, and should be considered to treat periodic limb movements of sleep in patients with PD (Level B). There is insufficient evidence to support or refute specific treatments for urinary incontinence, orthostatic hypotension, and anxiety (Level U). Future research should include concerted and interdisciplinary efforts toward finding treatments for nonmotor symptoms of PD.

    Reduced resilience, a construct associated with maladaptive stress coping and a predisposing vulnerability for Functional Neurological Disorders (FND), has been under-studied compared to other neuropsychiatric factors in FND. This prospective case-control study investigated self-reported resilience in patients with FND compared to controls and examined relationships between resilience and affective symptoms, personality traits, alexithymia, health status and adverse life event burden. 50 individuals with motor FND and 47 healthy controls participated. A univariate test followed by a logistic regression analysis investigated group-level differences in Connor-Davidson Resilience Scale (CD-RISC) scores. For within-group analyses performed separately in patients with FND and controls, univariate screening tests followed by multivariate linear regression analyses examined factors associated with self-reported resilience. Adjusting for age, gender, education status, ethnicity and lifetime adverse event burden, patients with FND reported reduced resilience compared to controls. Within-group analyses in patients with FND showed that individual-differences in mental health, extraversion, conscientiousness, and openness positively correlated with CD-RISC scores; post-traumatic stress disorder symptom severity, depression, anxiety, alexithymia and neuroticism scores negatively correlated with CD-RISC scores. Extraversion independently predicted resilience scores in patients with FND. In control subjects, univariate associations were appreciated between CD-RISC scores and gender, personality traits, anxiety, alexithymia and physical health; conscientiousness independently predicted resilience in controls. Patients with FND reported reduced resilience, and CD-RISC scores covaried with other important predisposing vulnerabilities for the development of FND. Future research should investigate if the CD-RISC is predictive of clinical outcomes in patients with FND. Copyright

    Full Text Available Neurological and psychiatric symptoms are consequences of substance abuse in schizophrenia and non-schizophrenia patients. The present case-control study examined changes in substance abuse/dependence and neurological and psychiatric symptoms in substance abusers with (DD group, n=26 and without schizophrenia (SUD group, n=24 and in non-abusing schizophrenia patients (SCZ group, n=23 undergoing 12-week treatment with the atypical antipsychotic, quetiapine. Neurological and psychiatric symptoms were evaluated with the Positive and Negative Syndrome Scale, the Calgary Depression Scale for Schizophrenia, the Extrapyramidal Symptoms Rating Scale and the Barnes Akathisia Rating Scale. At endpoint, DD and SCZ patients were receiving significantly higher doses of quetiapine (mean = 554mg/d and 478mg/d, respectively, relative to SUD patients (mean = 150mg/d. We found that SUD patients showed greater improvement in weekly dollars spent on alcohol and drugs and SUD severity, compared to DD patients. At endpoint, there was no significant difference in dollars spent, but DD patients still had a higher mean SUD severity. Interestingly, DD patients had significantly higher Parkinsonism and depression than SCZ patients at baseline and endpoint. On the other hand, we found that SUD patients had significantly more akathisia at baseline, improved more than SCZ patients and this was related to cannabis abuse/dependence. Finally, SUD patients improved more in PANSS positive scores than DD and SCZ patients. Taken together, our results provide evidence for increased vulnerability to the adverse effects of alcohol and drugs in schizophrenia patients. They also suggest that substance abuse/withdrawal may mimic some symptoms of schizophrenia. Future studies will need to determine the role quetiapine played in these improvements.

    Full Text Available Abstract Background Previous research by the authors found evidence that up to 10% of particular household categories may be exposed to elevated carbon monoxide (CO concentrations from poor quality gas appliance installations. The literature suggests certain neurological symptoms are linked to exposure to low levels of CO. This paper addresses the hypothesis that certain self-reported neurological symptoms experienced by a householder are linked to an estimate of their CO exposure. Methods Between 27 April and 27 June 2006, 597 homes with a mains supply of natural gas were surveyed, mainly in old, urban areas of London. Qualified gas engineers tested all gas appliances (cooker, boiler, gas fire, and water heater and reported, according to the Gas Industry Unsafe Situations Procedure, appliances considered At Risk (AR, Immediately Dangerous (ID or Not to Current Standards (NCS. Five exposure risk categories were defined based on measurement of CO emitted by the appliance, its features and its use, with "high or very high" exposure category where occupants were considered likely to be exposed to levels greater than 26 ppm for one hour. The prevalence of symptoms at each level of exposure was compared with that at lowest level of exposure. Results Of the households, 6% were assessed as having a "high or very high" risk of exposure to CO. Of the individuals, 9% reported at least one neurological symptom. There was a statistically significant association between "high or very high" exposure risk to CO and self-reported symptoms compared to "no exposure" likelihood, for households not in receipt of benefit, controlling for "number of residents" and presence of pensioners, OR = 3.23 (95%CI: 1.28, 8.15. Risk ratios across all categories of exposure likelihood indicate a dose-response pattern. Those households in receipt of benefit showed no dose-response pattern. Conclusion This study found an association between risk of CO exposure at low concentration

    Full Text Available Hyponatremia is a frequent electrolyte abnormality in patients with small cell lung cancer (SCLC. Being usually asymptomatic, hyponatremia may cause symptoms like nausea, fatigue, disorientation, headache, muscle cramps, or even seizures, particularly if severe and rapid decrease of serum sodium levels occurs. Here we report a case of SCLC patient with severe hyponatremia and acute neurological symptoms that developed 2 days after the first course of second-line chemotherapy, most probably due to the release of antidiuretic hormone (ADH, also known as arginine vasopressin during lysis of the tumour cells. Initial treatment consisted of continuous administration of hypertonic saline that resulted in improvement of patient’s neurological status. However, to obtain a persistent increase in serum sodium level, pharmacological intervention with oral fludrocortisone 0.1 mg twice daily was needed. We can therefore conclude that mineralocorticoids may be used to correct hyponatremia in SCLC patients when appropriate.

  1. The evidence for urodynamic investigation of patients with symptoms of urinary incontinence

    Urodynamic studies are the gold standard to objectively diagnose dysfunction of the lower urinary tract. The widely available evidence for the clinical relevance is, however, fragmented. This article summarizes the published knowledge supporting the use of urodynamic studies in urinary incontinence in female, male and frail patients, as well as patients with relevant neurological disease. Five technological innovations are discussed briefly. Standard urodynamic cystometry can, on the basis of a solid body of evidence, objectively unveil the entire function of the lower urinary tract in all patients with urinary incontinence, regardless of the patients' perception of (ab-)normality of signs and or symptoms.

    Stroke, Multiple Sclerosis (MS), traumatic brain injuries (TBI) and neuropathies are the most important diseases in neurological rehabilitation financed by the German Pension Insurance. The primary goal is vocational (re)integration. Driven by multiple findings of neuroscience research the traditional holistic approach with mainly empirically derived strategies was developed further and improved by new evidence-based interventions. This process had been, and continues to be, necessary to meet the health-economic pressures for ever shorter and more efficient rehab measures. Evidence-based interventions refer to symptom-oriented measures, to team-management concepts, as well as to education and psychosocial interventions. Drug therapy and/or neurophysiological measures can be added to increase neuroregeneration and neuroplasticity. Evidence-based aftercare concepts support sustainability and steadiness of rehab results.Mirror therapy, robot-assisted training, mental training, task-specific training, and above all constraint-induced movement therapy (CIMT) can restore motor arm and hand functions. Treadmill training and robot-assisted training improve stance and gait. Botulinum toxine injections in combination with physical and redressing methods are superior in managing spasticity. Guideline-oriented management of associated pain syndromes (myofascial, neuropathic, complex-regional=dystrophic) improve primary outcome and quality of life. Drug therapy with so-called co-analgetics and physical therapy play an important role in pain management. Swallowing disorders lead to higher mortality and morbidity in the acute phase; stepwise diagnostics (screening, endoscopy, radiology) and specific swallowing therapy can reduce these risks and frequently can restore normal eating und drinking.In our modern industrial societies communicative and cognitive disturbances are more impairing than the above mentioned disorders. Speech and language therapy (SLT) is dominant in

  3. The cerebro-morphological fingerprint of a progeroid syndrome: white matter changes correlate with neurological symptoms in xeroderma pigmentosum.

    Full Text Available BACKGROUND: Xeroderma pigmentosum (XP is a rare autosomal recessive progeroid syndrome. It has recently been shown that the underlying DNA repair defect plays a central role in the aging process. In addition to skin symptoms, various premature neurological abnormalities have been reported. METHODOLOGY/PRINCIPAL FINDINGS: We present the clinical neurological phenotype in 14 XP patients (seven subtypes, in seven of these patients together with conventional and multiparametric advanced MRI data to assess the macrostructural and microstructural cerebral morphology in comparison to controls, including volumetric measurements, MR spectroscopy ((1H MRS, and diffusion tensor imaging (DTI. Clinical hallmarks were spinocerebellar ataxia, pyramidal tract signs, and mild cognitive deficits. DTI demonstrated significantly reduced WM directionality in all regions investigated, i.e. the thalamus, the corticospinal tracts and the dorsal corpus callosum. Single patients showed a marked relative hippocampal volume reduction, but the patients were not different from controls in the volumetric measurements of hippocampal and whole brain volumes at group level. However, (1H MRS demonstrated that the hippocampal formation was metabolically altered. CONCLUSIONS: The most prominent feature was the white matter affectation, as assessed by DTI, with volume and directionality reductions of the fiber projections involving both the craniocaudal fibers and the interhemispheric connections. These findings, although heterogeneous among the study sample, could be correlated with the clinico-neurological symptoms. The imaging findings support the position that myelin structures degrade prematurely in the brain of XP patients.

    Full Text Available Purpose : Hand-foot-mouth disease (HFMD is a common viral illness in children, which is usually mild and self-limiting. However, in recent epidemics of HFMD in Asia, enterovirus 71 (EV71 has been recognized as a causative agent with severe neurological symptoms with or without cardiopulmonary involvement. HFMD was epidemic in Korea in the spring of 2009. Severe cases with complications including death have been reported. The clinical characteristics in children with neurologic manifestations of EV71 were studied in Ewha Womans University Mokdong Hospital. Methods : Examinations for EV71 were performed from the stools, respiratory secretion or CSF of children who presented neurologic symptoms associated with HFMD by realtime PCR. Clinical and radiologic data of the patients were collected and analyzed. Results : EV71 was isolated from the stool of 16 patients but not from respiratory secretion or CSF. Among the 16 patients, meningitis (n=10 was the most common manifestation, followed by Guillain-Barr&eacute; syndrome (n=3, meningoencephalitis (n=2, poliomyelitis-like paralytic disease (n=1, and myoclonus (n=1. Gene analysis showed that most of them were caused by EV71 subgenotype C4a, which was prevalent in China in 2008. Conclusion : Because EV71 causes severe complications and death in children, a surveillance system to predict upcoming outbreaks should be established and maintained and adequate public health measures are needed to control disease.

    Full Text Available This work deals with the special features of formation of individual clinical phenotype with an evident humoral sensitizing in patients with arterial hypotension in structure of neurologic symptom complexes of organic lesion of the central nervous system in accordance with the features of disorders of immune resistance and changes of the hormonal background.Materials and methods. There was carried out an examination of 201 patients: 89 with vegetative dysfunction, 50 in remote period of the closed craniocerebral trauma and 64 with cerebral arachnoiditis on the background of the chronic nidi of infection.45 examined persons with physiological arterial hypotension formed a control group. There were carried out clinical and neurological examinations, monitoring of arterial pressure, definition of the state of the primary, secondary immunity and hormonal background.Results. The main pathogenetic mechanisms in individual clinical phenotype with an evident humoral sensitizing that were formed on the background of the chronic infection are more connected with the humoral link of immunity (the high concentration of circulating immune complexes of the small values of molecular weight and peptides of the mean molecular weight, the growth of IgM content and form autoimmune disorders. This category can be related to the patients with irreversible functional states that complicates prescription of therapeutic measures.Conclusions. For patients with an evident humoral sensitizing it is reasonable to use desensitizing preparations, enterosorbents, plasmapheresis in the complex treatment. At persistent viral infection the use of specific antiviral immunoglobulins of IgG is recommended

    To systematically review how process evaluations are currently designed, what methodologies are used and how are they developed alongside or within neurological rehabilitation trials. This mixed-methods systematic review had two evidence streams: stream I, studies reporting process evaluations alongside neurorehabilitation trials research and stream II, methodological guidance on process evaluation design and methodology. A search strategy was designed for each evidence stream. Data regarding process evaluation core concepts and design issues were extracted using a bespoke template. Evidence from both streams was analysed separately and then synthesised in a final overarching synthesis proposing a number of recommendations for future research. A total of 124 process evaluation studies, reporting on 106 interventions, were included in stream I evidence. 30 studies were included as stream II evidence. Synthesis 1 produced 9 themes, and synthesis 2 identified a total of 8 recommendations for process evaluation research. The overall synthesis resulted in 57 'synthesis recommendations' about process evaluation methodology grouped into 9 research areas, including the use of theory, the investigation of context, intervention staff characteristics and the delivery of the trial intervention. There remains no consensus regarding process evaluation terminology within the neurological rehabilitation field. There is a need for process evaluations to address the nature and influence of context over time. Process evaluations should clearly describe what intervention staff bring to a trial, including skills and experience prior to joining the research. Process evaluations should monitor intervention staff's learning effects and the possible impact that these may have on trial outcomes. Published by the BMJ Publishing Group Limited.

    Full Text Available Moyamoya disease is a rare neurological condition that affects children and adults of all ages. It is characterized by chronic, progressive stenosis of the circle of Willis that ultimately leads to the development of extensive collateral vessels. Presenting symptoms are usually due to cerebral ischemia or hemorrhage. The Japanese term moyamoya (meaning puffy or obscure was coined to describe the characteristic ‘smoke in the air’ appearance of these vessels on cerebral angiography. Moyamoya has the highest recorded incidence in Japan (0.28 per 100,000. In the west it is an extremely rare condition with an overall incidence of (0.086 per 100,000 in the Western United States. Etiology for the most part is unknown; however, genetic susceptibility related to RNF213 gene on chromosome 17q25.3 has been suggested. Moyamoya is being diagnosed more frequently in all races with varying clinical manifestations. Moyamoya disease is a rare progressive neurologic condition characterized by occlusion of the cerebral circulation with extensive collaterals recruitment in children and adults. Distinguished radiological findings confirm the diagnosis. Early recognition and swift institution of therapy is vital in order to minimize neurological deficits. We present the case of a 19-year-old African American female who presented with left-sided parastheia, weakness, and headache for 2 days duration.

    Epidural lipomatosis is a rare condition in which overgrowth of extradural fat can lead to back pain, spinal cord compression and radiculopathy. A 51-year-old man developed back pain and reduced mobility following a standard course of radiotherapy for a Stage I seminoma. His symptoms and radiological appearances were initially attributed to radiation fibrosis. Further investigations and operative intervention revealed epidural lipomatosis. The excess lipomatous tissue was removed with complete resolution of his symptoms.

    Dengue is a flavivirus of the genus arbovirus with four serotypes, from DEN 1 to DEN 4. There has been an increase in incidence of dengue infection in children in the tropics and subtropics. Dengue has a variable clinical presentation, with many patients being asymptomatic. Its clinical manifestations in children vary from fever and arthralgia to life-threatening dengue hemorrhagic fever and dengue shock syndrome. We describe MRI findings in children with neurological involvement including dengue encephalopathy, acute hypoxic injury and dengue encephalitis. Dengue encephalopathy is usually secondary to multisystem derangement such as shock, hepatitis, coagulopathy and concurrent bacterial infection and is relatively common. Dengue encephalitis from direct neuronal invasion is rare. Nonspecific changes are seen on brain MRI in dengue infection. Clinical and laboratory findings as well as outcome do not necessarily correspond with brain MRI findings. (orig.)

    In their 1973 BMJ paper 'Cryptogenic Drop Attacks', Stevens and Matthews described 40, mostly middle-aged, female patients with drop attacks of unknown cause. Although clinically common, there has been little on this topic since. We aimed to determine clinical features, comorbidity and outcome of patients with drop attacks. We carried out a retrospective review of patients with cryptogenic drop attacks seen consecutively by one clinician (JS) between 2006 and 2016. Demographics, phenomenology, duration and frequency of attacks, attack description and comorbid diagnoses were recorded. Patients were followed up with a notes review. 83 patients with cryptogenic drop attacks were predominantly female (89%, n=79), mean age 44  years. The majority (93%, n=77) could not remember the fall itself and almost half (43%, n=36) experienced prodromal dissociative symptoms. Mechanical trips or syncope preceded drop attacks, historically, in 24% (n=20) of cases. Persistent fatigue (73%, n=61), chronic pain (40%, n=33), functional limb weakness (31%,n=26) and dissociative (non-epileptic) attacks 28% (n=23) were common, with the latter usually preceding or emerging from drop attacks. At follow-up (88%, mean 38 months), 28% (n=23) had resolution of their drop attacks. Predisposing (but non-causative) disease comorbidity was found at baseline (n=12) and follow-up (n=5). Cryptogenic drop attacks are associated with high frequency of comorbid functional somatic and functional neurological disorders. Patients commonly have prodromal dissociative symptoms and in some there was a clear relationship with prior or subsequent dissociative (non-epileptic) attacks. Some cryptogenic drop attacks may be best understood as phenomena on the spectrum of dissociative attacks. © Article author(s) (or their employer(s) unless otherwise stated in the text of the article) 2018.

  12. Complex neurological symptoms in bilateral thalamic stroke due to Percheron artery occlusion.

    Caruso, Paola; Manganotti, Paolo; Moretti, Rita

    2017-01-01

    The artery of Percheron is a rare anatomical variant where a single thalamic perforating artery arises from the proximal posterior cerebral artery (P1 segment) between the basilar artery and the posterior communicating artery and supplies the rostral mesencephalon and both paramedian territories of the thalami. Almost one-third of human brains present this variant. Occlusion of the artery of Percheron mostly results in a bilateral medial thalamic infarction, which usually manifests with altered consciousness (including coma), vertical gaze paresis, and cognitive disturbance. The presentation is similar to the "top of the basilar syndrome", and early recognition should be prompted. We describe the case of a young female with this vessel variant who experienced a bilateral thalamic stroke. Magnetic resonance angiography demonstrated bilateral thalamic infarcts and a truncated artery of Percheron. Occlusion of the vessel was presumably due to embolism from a patent foramen ovale. Thrombolysis was performed, with incomplete symptom remission, cognitive impairment, and persistence of speech disorders. Early recognition and treatment of posterior circulation strokes is mandatory, and further investigation for underlying stroke etiologies is needed.

    To update the 1997 American Academy of Neurology (AAN) practice parameter regarding sports concussion, focusing on 4 questions: 1) What factors increase/decrease concussion risk? 2) What diagnostic tools identify those with concussion and those at increased risk for severe/prolonged early impairments, neurologic catastrophe, or chronic neurobehavioral impairment? 3) What clinical factors identify those at increased risk for severe/prolonged early postconcussion impairments, neurologic catastrophe, recurrent concussions, or chronic neurobehavioral impairment? 4) What interventions enhance recovery, reduce recurrent concussion risk, or diminish long-term sequelae? The complete guideline on which this summary is based is available as an online data supplement to this article. We systematically reviewed the literature from 1955 to June 2012 for pertinent evidence. We assessed evidence for quality and synthesized into conclusions using a modified Grading of Recommendations Assessment, Development and Evaluation process. We used a modified Delphi process to develop recommendations. Specific risk factors can increase or decrease concussion risk. Diagnostic tools to help identify individuals with concussion include graded symptom checklists, the Standardized Assessment of Concussion, neuropsychological assessments, and the Balance Error Scoring System. Ongoing clinical symptoms, concussion history, and younger age identify those at risk for postconcussion impairments. Risk factors for recurrent concussion include history of multiple concussions, particularly within 10 days after initial concussion. Risk factors for chronic neurobehavioral impairment include concussion exposure and APOE ε4 genotype. Data are insufficient to show that any intervention enhances recovery or diminishes long-term sequelae postconcussion. Practice recommendations are presented for preparticipation counseling, management of suspected concussion, and management of diagnosed concussion.

    To make evidence-based recommendations for screening, diagnosing, and treating psychiatric disorders in individuals with multiple sclerosis (MS). We reviewed the literature (1950 to August 2011) and evaluated the available evidence. Clinicians may consider using the Center for Neurologic Study Emotional Lability Scale to screen for pseudobulbar affect (Level C). Clinicians may consider the Beck Depression Inventory and a 2-question tool to screen for depressive disorders and the General Health Questionnaire to screen for broadly defined emotional disturbances (Level C). Evidence is insufficient to support/refute the use of other screening tools, the possibility that somatic/neurovegetative symptoms affect these tools' accuracy, or the use of diagnostic instruments or clinical evaluation procedures for identifying psychiatric disorders in MS (Level U). Clinicians may consider a telephone-administered cognitive behavioral therapy program for treating depressive symptoms (Level C). Although pharmacologic and nonpharmacologic therapies are widely used to treat depressive and anxiety disorders in individuals with MS, evidence is insufficient to support/refute the use of the antidepressants and individual and group therapies reviewed herein (Level U). For pseudobulbar affect, a combination of dextromethorphan and quinidine may be considered (Level C). Evidence is insufficient to determine the psychiatric effects in individuals with MS of disease-modifying and symptomatic therapies and corticosteroids; risk factors for suicide; and treatment of psychotic disorders (Level U). Research is needed on the effectiveness in individuals with MS of pharmacologic and nonpharmacologic treatments frequently used in the non-MS population.

    Full Text Available Neonicotinoid insecticides are nicotinic acetylcholine receptor agonists used worldwide. Their environmental health effects including neurotoxicity are of concern. We previously determined a metabolite of acetamiprid, N-desmethyl-acetamiprid in the urine of a patient, who exhibited some typical symptoms including neurological findings. We sought to investigate the association between urinary N-desmethyl-acetamiprid and the symptoms by a prevalence case-control study. Spot urine samples were collected from 35 symptomatic patients of unknown origin and 50 non-symptomatic volunteers (non-symptomatic group, NSG, 4-87 year-old. Patients with recent memory loss, finger tremor, and more than five of six symptoms (headache, general fatigue, palpitation/chest pain, abdominal pain, muscle pain/weakness/spasm, and cough were in the typical symptomatic group (TSG, n = 19, 5-69 year-old; the rest were in the atypical symptomatic group (ASG, n = 16, 5-78 year-old. N-desmethyl-acetamiprid and six neonicotinoids in the urine were quantified by liquid chromatography-tandem mass spectrometry. The detection of N-desmethyl-acetamiprid was the most frequent and highest in TSG (47.4%, 6.0 ppb (frequency, maximum, followed by in ASG (12.5%, 4.4 ppb and in NSG (6.0%, 2.2 ppb, however acetamiprid was not detected. Thiamethoxam was detected in TSG (31.6%, 1.4 ppb, in ASG (6.3%, 1.9 ppb, but not in NSG. Nitenpyram was detected in TSG (10.5%, 1.2 ppb, in ASG (6.3%, not quantified and in NSG (2.0%, not quantified. Clothianidin was only detected in ASG (6.3%, not quantified, and in NSG (2.0%, 1.6 ppb. Thiacloprid was detected in ASG (6.3%, 0.1 ppb. The cases in TSG with detection of N-desmethyl-acetamiprid and thiamethoxam were aged 5 to 62 years and 13 to 62 years, respectively. Detection of N-desmethyl-acetamiprid was associated with increased prevalence of the symptoms (odds ratio: 14, 95% confidence interval: 3.5-57. Urinary N-desmethyl-acetamiprid can be used as a

    Subjective cognitive impairment (SCI), depressive symptoms, and fatigue are common after stroke and are associated with reduced quality of life. We prospectively investigated their prevalence and course after a transient ischemic attack (TIA) or nonfocal transient neurological attack (TNA) and the association with diffusion-weighted imaging (DWI) lesions. The Cognitive Failures Questionnaire, Hospital Anxiety and Depression Scale, and Subjective Fatigue subscale from the Checklist Individual Strength were used to assess subjective complaints shortly after TIA or TNA and six months later. With repeated measure analysis, the associations between DWI lesion presence or clinical diagnosis (TIA or TNA) and subjective complaints over time were determined. We included 103 patients (28 DWI positive). At baseline, SCI and fatigue were less severe in DWI positive than in DWI negative patients, whereas at follow-up, there were no differences. SCI ( p = 0.02) and fatigue ( p = 0.01) increased in severity only in DWI positive patients. There were no differences between TIA and TNA. Subjective complaints are highly prevalent in TIA and TNA patients. The short-term prognosis is not different between DWI-positive and DWI negative patients, but SCI and fatigue increase in severity within six months after the event when an initial DWI lesion is present.

    Full Text Available Objective To discuss the clinical effects of minimally invasive percutaneous pedicle screw fixation in the treatment of single segment thoracolumbar fracture without neurological symptoms.  Methods From June 2012 to October 2014, 38 neurologically intact patients with thoracolumbar fracture underwent surgeries, including open pedicle screw fixation in 16 cases and percutaneous pedicle screw fixation in 22 cases. The incision length, operation time, intraoperative blood loss, postoperative drainage and postoperative complication were recorded and compared between 2 groups. Thoracolumbar orthophoric, lateral and flexion-extension X-ray was used to measure sagittal Cobb angle and height of injured anterior vertebral body before and after operation. Modified Macnab evaluation was used to assess the curative effects 3 months after operation. Results The success rate of operations in 38 patients was 100%. There were a total of 114 vertebral bodies fused and 228 pedicle screws implanted. Patients in the percutaneous pedicle screw group had smaller incision length [(10.55 ± 1.23 cm vs (18.50 ± 2.50 cm, P = 0.000], less intraoperative blood loss [(32.55 ± 7.22 ml vs (320.50 ± 15.48 ml, P = 0.000], shorter hospital stay [(6.55 ± 1.50 d vs (13.50 ± 2.52 d, P = 0.000], and without postoperative drainage. The follow-up after operation ranged from 3 to 6 months, with the average time of (4.65 ± 1.24 months. Cobb angle was reduced (P = 0.000 and height of injured anterior vertebral body were improved signifcantly (P = 0.000 3 months after surgery in both groups. The total effective rate was 14/16 in open surgery group, and 86.36% (19/22 in percutaneous pedicle screw group, however, the difference between 2 groups was not significant (P = 1.000. Conclusions Minimally invasive percutaneous pedicle screw fixation is a surgical method with less iatrogenic injury, less intraoperative blood loss and quick recovery for patients with thoracolumbar fracture

    The aim of the study was to evaluate the bioavailability and clinical benefits of oral new formulation (HB 12 ) of hydroxocobalamin (Hdrx) with Hibiscus sabdariffa (HS). First, in an observational study, a cohort of 30 vitamin B 12 -deficient patients (vit B 12 < 200 pg/mL) with neurological symptoms received oral fixed dose of Hdrx containing 15 mg Hdrx daily for 10 days followed by 15 mg monthly. Clinical benefits were evaluated on haematological and biochemical parameters, and neurological improvement at days 10 and 90 compared to day 0. To understand the mechanism, intestinal mucosa from mice were mounted in vitro in Ussing chambers to measure Hdrx Fluxes. In the clinical study, serum vitamin B 12 level increased from 55.1 ± 36.9 to 1330 ± 335.5 pg/mL at day 10 and 431.0 ± 24.27 pg/mL at day 90, without overt adverse effects. In mice ileum, (i) intestinal bioavailability of Hdrx increased in dose-dependent manner with HB 12 . The apparent permeability of Hdrx was P app = 34.9 ± 4.6 × 10 -6 cm/s in the presence of 3 mg/mL (HB 12 B) compared to the control P app = 6.2 ± 0.7 × 10 -6 cm/s. (ii) Total transepithelial electrical conductance (G t ) increased in dose-dependent manner with HB 12 , G t = 161.5 ± 10.8 mS/cm² with HB 12 B (Hdrx 1 mg + HS 3 mg) compared to the control Hdrx, G t = 28.7 ± 4.0 mS/cm². In conclusion, the clinical study suggests that injections are not required when Hdrx is given orally. Intestinal bioavailability of Hdrx increased in vitro when it was used concomitantly with HS. © 2016 Société Française de Pharmacologie et de Thérapeutique.

    Thirty-one individuals awaiting trial or sentencing for murder or undergoing an appeal process requested a neurologic examination through legal counsel. We attempted in each instance to obtain EEG, MRI or CT, and neuropsychological testing. Neurologic examination revealed evidence of "frontal" dysfunction in 20 (64.5%). There were symptoms or some other evidence of temporal lobe abnormality in nine (29%). We made a specific neurologic diagnosis in 20 individuals (64.5%), including borderline or full mental retardation (9) and cerebral palsy (2), among others. Neuropsychological testing revealed abnormalities in all subjects tested. There were EEG abnormalities in eight of the 20 subjects tested, consisting mainly of bilateral sharp waves with slowing. There were MRI or CT abnormalities in nine of the 19 subjects tested, consisting primarily of atrophy and white matter changes. Psychiatric diagnoses included paranoid schizophrenia (8), dissociative disorder (4), and depression (9). Virtually all subjects had paranoid ideas and misunderstood social situations. There was a documented history of profound, protracted physical abuse in 26 (83.8%) and of sexual abuse in 10 (32.3%). It is likely that prolonged, severe physical abuse, paranoia, and neurologic brain dysfunction interact to form the matrix of violent behavior.

    There is a wide range of indications for radiographic evaluation of possible cerebrovascular disease, since a wide range of neurologic symptoms can be encountered secondary to ischemia. Frequently the diagnosis of cerebrovascular disease is clear on clinical grounds, but radiographic evaluation is essential both to quantify the extent of disease and establish the underlying cause (e.g., vasculitis, embolus) while excluding other causes so that the proper therapy can follow

    To investigate whether synchronising over-ground walking to rhythmic auditory cues improves temporal and spatial gait measures in adults with neurological clinical conditions other than Parkinson's disease. A search was performed in June 2011 using the computerised databases AGELINE, AMED, AMI, CINAHL, Current Contents, EMBASE, MEDLINE, PsycINFO and PUBMED, and extended using hand-searching of relevant journals and article reference lists. Methodological quality was independently assessed by two reviewers. A best evidence synthesis was applied to rate levels of evidence. Fourteen studies, four of which were randomized controlled trials (RCTs), met the inclusion criteria. Patient groups included those with stroke (six studies); Huntington's disease and spinal cord injury (two studies each); traumatic brain injury, dementia, multiple sclerosis and normal pressure hydrocephalus (one study each). The best evidence synthesis found moderate evidence of improved velocity and stride length of people with stroke following gait training with rhythmic music. Insufficient evidence was found for other included neurological disorders due to low study numbers and poor methodological quality of some studies. Synchronising walking to rhythmic auditory cues can result in short-term improvement in gait measures of people with stroke. Further high quality studies are needed before recommendations for clinical practice can be made.

  4. Evidence for the Importance of Vitamin D Status in Neurologic Conditions.

    2015-12-01

    Vitamin D status has been proposed as relevant to many neurological disorders. Data suggest that vitamin D may be important for the development of the nervous system, and it also plays a role in neuroimmunology and neuroprotection. Lower levels of circulating 25-hydroxyvitamin D have been linked with increased risk of multiple sclerosis (MS) and Alzheimer's disease (AD). While people with amyotrophic lateral sclerosis (ALS), Parkinson's disease (PD), and stroke have lower vitamin D levels than those without the diseases, it is unclear if this is because hypovitaminosis D contributes to disease risk or is a consequence of immobility and other factors caused by the disease. Lower levels of vitamin D have been associated with worse prognosis in MS, PD, ALS, and stroke, while no longitudinal studies have been performed to evaluate such an association in AD. Small pilot trials have been performed to evaluate vitamin D supplementation for some of these diseases, but there have been no phase III studies to support vitamin D supplementation in these patient populations; further, ideal levels of 25-hydroxyvitamin D are not known. Thus, while some expert panels or individuals have suggested routine testing and supplementation for patients with these neurological conditions, it is our opinion that there are currently insufficient data to support high-dose vitamin D supplementation to specifically treat or prevent these conditions.

    Virtual reality (VR) is an emerging area of paediatric clinical and research practice, however the majority of research to date has focused on outcomes for adults following stroke. This paper appraises and describes current evidence for use of virtual reality interventions to improve upper limb function of children with neurological impairment. A comprehensive database search was undertaken to explore literature on the use of VR systems for rehabilitation of upper limb skills of children with neurological impairment. Studies investigating the use of robotics or other mechanical devices were excluded. Five studies were found and were critiqued using the Downs and Black scale for measuring study quality. One randomized control trial and four case studies were found. No study scored over 50% on the Downs and Black scale, indicating methodological limitations that limit generalizability. Current evidence for the use of VR to improve hand and arm skills is at an emerging stage. Small sample sizes and inconsistencies in outcome measurement limit the ability to generalize findings. Further studies are required to investigate the ability to maintain gains made in VR over time and to determine whether gains transfer from the VR to real life tasks and activities.

    History of traumatic experience is common in dissociative disorder (DD), and similarity of symptoms and characteristics between DD and posttraumatic stress disorder (PTSD) encouraged to consider DD as trauma-related disorder. However, conceptualization of DD as a trauma-related syndrome would critically affect diagnosis and treatment strategies. The present study addressed overlap and disparity of DD and PTSD by directly comparing correspondence of symptoms, adverse/traumatic experience, and altered affect regulation between patients diagnosed with dissociative disorder (characterized by negative functional neurological symptoms) and patients diagnosed with PTSD. Somatoform and psychoform dissociation, symptoms of posttraumatic stress, general childhood adversities and lifetime traumata, and alexithymia as index of altered affect regulation were screened with standardized questionnaires and semi-structured interviews in 60 patients with DD (ICD-codes F44.4, F44.6, F44.7), 39 patients with PTSD (ICD-code F43.1), and 40 healthy comparison participants (HC). DD and PTSD patients scored higher than HC on somatoform and psychoform dissociative symptom scales and alexithymia, and reported more childhood adversities and higher trauma load. PTSD patients reported higher symptom severity and more traumata than DD patients. Those 20 DD patients who met criteria of co-occuring PTSD did not differ from PTSD patients in the amount of reported symptoms of somatoform dissociation, physical and emotional childhood adversities and lifetime traumata, while emotional neglect/abuse in childhood distinguished DD patients with and without co-occuring PTSD (DD patients with co-occuring PTSD reporting more emotional maltreatment). The pattern of distinctive somatoform and psychoform dissociative symptom severity, type of childhood and lifetime traumata, and amount of alexithymia suggests that DD and PTSD are distinctive syndromes and, therefore, challenges the conceptualization of DD as

    The optimal timing for surgery for patients with spinal cord injury without radiographic evidence of trauma (SCIWORET) remains unclear. This is especially true in the elderly, given that most studies are done with younger patients to avoid age-related comorbidities. We aimed to compare the efficacy of early (24 hours postinjury) surgery in patients with SCIWORET aged ≥65 years. We identified patients aged ≥65 years who underwent surgery for SCIWORET between January 1995 and February 2016. The primary outcome was a change in the Japanese Orthopaedic Association (JOA) score at discharge, with a recovery of >50% defined as a favorable neurologic outcome. Logistic regression analysis was performed, and model fit was assessed using the Hosmer-Lemeshow test. Eighty patients aged ≥65 years with SCIWORET underwent surgery were enrolled. Favorable neurologic outcomes were seen in 43.3% of those who underwent early surgery, but only in 18.0% of those who underwent late surgery. Logistic regression analysis, adjusted for age, sex, comorbidities (Charlson Comorbidity Index), and JOA score, revealed that early surgery independently predicted favorable outcomes (odds ratio, 4.06; 95% confidence interval, 1.25-13.20), with excellent calibration (Hosmer-Lemeshow, P = 0.857). The present study indicated that early surgery within 24 hours of injury for elderly patients with SCIWORET could lead to more favorable neurologic improvements. We believe that chronological age alone should not be considered sufficient justification to deny patients early surgical decompression for SCIWORET. Copyright © 2017 Elsevier Inc.

    Severe neurological symptoms in Shiga toxin-producing Escherichia coli infection associated hemolytic-uremic syndrome (STEC-HUS) are often accompanied by none or only mild alterations of cerebral magnetic resonance imaging (MRI). This study aims to analyze if quantitative MRI is able to reveal cerebral pathological alterations invisible for conventional MRI. In nine patients with STEC-HUS associated severe neurological symptoms but inconspicuous cerebral MRI findings maps of the parameters T2 relaxation time, relative proton density (PD), apparent diffusion coefficient (ADC), and fractional anisotropy (FA) were generated. Quantitative values of these parameters were measured at the basal ganglia, thalamus, and white matter of the frontal and parietal lobe and compared to those of nine age- and sex-matched controls. Significant T2 prolongation (p < 0.01) was found in the basal ganglia of all patients compared to controls. PD and ADC were not significantly altered. A significant reduction of FA in patients was seen at caput nuclei caudati (p < 0.01). Prolonged T2 relaxation time indicates cerebral microstructural damages in these patients despite their inconspicuous MRI findings. T2 relaxometry could be used as a complementary tool for the assessment of metabolic-toxic brain syndromes. (orig.)

    Niemann-Pick disease type C (NP-C) is a rare inherited neurovisceral disease that should be recognised by psychiatrists as a possible underlying cause of psychiatric abnormalities. This study describes NP-C patients who had psychiatric manifestations at enrolment in the international NPC Registry, a unique multicentre, prospective, observational disease registry. Treating physicians' data entries describing psychiatric manifestations in NPC patients were coded and grouped by expert psychiatrists. Out of 386 NP-C patients included in the registry as of October 2015, psychiatric abnormalities were reported to be present in 34% (94/280) of those with available data. Forty-four patients were confirmed to have identifiable psychiatric manifestations, with text describing these psychiatric manifestations. In these 44 patients, the median (range) age at onset of psychiatric manifestations was 17.9 years (2.5-67.9; n = 15), while the median (range) age at NP-C diagnosis was 23.7 years (0.2-69.8; n = 34). Almost all patients (43/44; 98%) had an occurrence of ≥1 neurological manifestation at enrolment. These data show that substantial delays in diagnosis of NP-C are long among patients with psychiatric symptoms and, moreover, patients presenting with psychiatric features and at least one of cognitive impairment, neurological manifestations, and/or visceral symptoms should be screened for NP-C.

    To evaluate the significance of inborn metabolic disorders of the pyrimidine degradation pathway, 450 children with unspecific neurological symptoms were comprehensively studied; 200 healthy children were recruited as controls. Uracil and thymine as well as their degradation products in urine were determined with an improved method based on reversed-phase HPLC coupled with electrospray ionization tandem mass spectrometry and detection by multiple-reaction monitoring using stable-isotope-labelled reference compounds as internal standards. From the results of the control group we established age-related reference ranges of all pyrimidine degradation products. In the patient group, two children with dihydropyrimidine dehydrogenase (DPYD) deficiency were identified; one of these was homozygous for the exon 14-skipping mutation of the DPYD gene. In addition, two patients with high uracil, dihydrouracil and beta-ureidopropionate were found to have ornithine transcarbamylase deficiency. In the urine of 9 patients, beta-alanine was markedly elevated owing to treatment with vigabatrin, an irreversible inhibitor of GABA transaminase, which interferes with beta-alanine breakdown. Four patients had exclusively high levels of beta-aminoisobutyrate (beta-AIB) due to a low activity of the D-beta-AIB-pyruvate aminotransferase, probably without clinical significance. In conclusion, quantitative investigation of pyrimidine metabolites in children with unexplained neurological symptoms, particularly epileptic seizures with or without psychomotor retardation, can be recommended as a helpful tool for diagnosis in clinical practice. Sensitive methods and age-related reference ranges enable the detection of partial enzyme deficiencies.

    To provide an update of the 1995 American Academy of Neurology guideline with regard to the following questions: Are there patients who fulfill the clinical criteria of brain death who recover neurologic function? What is an adequate observation period to ensure that cessation of neurologic function is permanent? Are complex motor movements that falsely suggest retained brain function sometimes observed in brain death? What is the comparative safety of techniques for determining apnea? Are there new ancillary tests that accurately identify patients with brain death? A systematic literature search was conducted and included a review of MEDLINE and EMBASE from January 1996 to May 2009. Studies were limited to adults. In adults, there are no published reports of recovery of neurologic function after a diagnosis of brain death using the criteria reviewed in the 1995 American Academy of Neurology practice parameter. Complex-spontaneous motor movements and false-positive triggering of the ventilator may occur in patients who are brain dead. There is insufficient evidence to determine the minimally acceptable observation period to ensure that neurologic functions have ceased irreversibly. Apneic oxygenation diffusion to determine apnea is safe, but there is insufficient evidence to determine the comparative safety of techniques used for apnea testing. There is insufficient evidence to determine if newer ancillary tests accurately confirm the cessation of function of the entire brain.

    Retrospective study. To investigate the safety to leave a syrinx untreated in 1-stage correction surgery of scoliosis associated with syringomyelia without progressive neurological symptom. The present protocol for patients with scoliosis secondary to syringomyelia advocated to treat the syrinx first because of the increased risk in correction surgery. However, in daily life, these patients could still do lateral bending, in which spinal cord distracted albeit without any neurological symptom occurred. Twenty-one consecutive patients with scoliosis associated with syringomyelia with or without Chiari malformation underwent surgery in our department from 2003 to 2010 were included in this study. Patients with progressive neural deficits were excluded. Every patient received detailed neurological and radiologic examination before the surgery, including whole spine films, lateral-bending and fulcrum-bending films, 3-dimensional computed tomography scan, and magnetic resonance imaging. All the patients underwent 1-stage correction surgery without treatment of syrinx. During the surgery, Spinal Cord Monitor (SCM) and wake-up test were used to prevent serious neurological complications. At follow-up, patients received neurological examination and whole spine x-ray films. There were 13 male and 8 female patients. Before the surgery, 3 patients complained wasting of the intrinsic muscles of hand, 1 complained numbness of left upper extremity, and 4 complained back pain. Negative abdomen reflex occurred on 12 of 21 patients. All the patients were single major curve, including 14 thoracic curves and 7 thoracolumbar curves. The mean preoperative Cobb angle of scoliosis was 68.05±20.1 degrees, on bending films was 39.48±21.56 degrees, postoperative was 23.19±14.14 degrees, at final follow-up was 25.76±14.46 degrees. The mean flexibility was 0.452±0.158, correction ratio was 0.685±0.140. During the operation, SCM showed motor evoked potential (MEP) loss transiently in 2

    Full Text Available Neurologic side effects related to cancer therapy are a common problem in oncology practice. These complications can negatively affect the management of the patient, because they can inhibit treatment and diminish quality of life. Therefore specific skills are required to recognise symptoms and clinical manifestations. This review focuses on the most common neurologic complications to improve physician’s familiarity in determining the aetiology of these symptoms.

    It has been approximately 70 years since the discovery of the Zika virus (ZIKV). It had been established that the virus causes mild infections and is confined to Africa and Asia; however, major changes in the clinical and epidemiologic patterns of ZIKV infection have occurred in recent years. The virus has attracted intense interest because of the possible association of several autoimmune and neurodevelopmental disorders. We present a summary of the articles that attempt to explain the ZIKV unknowns and strengthen the association with some disorders that are thought to be related to ZIKV, by describing the discovery milestones from the initial identification of the virus to the present day. New evidence strengthens the association between ZIKV infections and Guillain-Barré syndrome (GBS), microcephaly and various neurodevelopmental and ophthalmologic disorders as a result of numerous new clinical and experimental studies. The World Health Organization declared the end of the "Public Health Emergency of International Concern" in December 2016, but ZIKV and associated consequences remain a significant enduring public health challenge.

    In consecutive new outpatients, we aimed to assess whether somatization and health anxiety predicted health care use and quality of life 6 months later in all patients or in those without demonstrable abnormalities. On the first clinic visit, participants completed the Illness Perception Questionnaire (IPQ), the Health Anxiety Questionnaire (HAQ), and the Hospital Anxiety and Depression Scale (HADS). Outcome was assessed as: (a) the number of medical consultations over the subsequent 6 months, extracted from medical records, and (b) Short-Form Health Survey 36 (SF36) physical component score 6 months after index clinic visit. A total of 295 patients were recruited (77% response rate), and medical consultation data were available for 275. The number of bodily symptoms was associated with both outcomes in linear fashion (Psomatization and hypochondriasis.

    To make evidence-based recommendations regarding management of tardive syndromes (TDS), including tardive dyskinesias (TDD), by addressing 5 questions: 1) Is withdrawal of dopamine receptor blocking agents (DRBAs) an effective TDS treatment? 2) Does switching from typical to atypical DRBAs reduce TDS symptoms? 3) What is the efficacy of pharmacologic agents in treating TDS? 4) Do patients with TDS benefit from chemodenervation with botulinum toxin? 5) Do patients with TDS benefit from surgical therapy? PsycINFO, Ovid MEDLINE, EMBASE, Web of Science, and Cochrane were searched (1966-2011). Articles were classified according to a 4-tiered evidence-rating scheme; recommendations were tied to the evidence. Clonazepam probably improves TDD and ginkgo biloba probably improves TDS (both Level B); both should be considered as treatment. Risperidone may improve TDS but cannot be recommended as treatment because neuroleptics may cause TDS despite masking symptoms. Amantadine and tetrabenazine might be considered as TDS treatment (Level C). Diltiazem should not be considered as TDD treatment (Level B); galantamine and eicosapentaenoic acid may not be considered as treatment (Level C). Data are insufficient to support or refute use of acetazolamide, bromocriptine, thiamine, baclofen, vitamin E, vitamin B6, selegiline, clozapine, olanzapine, melatonin, nifedipine, fluperlapine, sulpiride, flupenthixol, thiopropazate, haloperidol, levetiracetam, quetiapine, ziprasidone, sertindole, aripiprazole, buspirone, yi-gan san, biperiden discontinuation, botulinum toxin type A, electroconvulsive therapy, α-methyldopa, reserpine, and pallidal deep brain stimulation as TDS treatments (Level U). Data are insufficient to support or refute TDS treatment by withdrawing causative agents or switching from typical to atypical DRBA (Level U).

    Storage lower urinary tract symptoms (LUTS) are characterized by an altered bladder sensation, increased daytime frequency, nocturia, urgency and urgency incontinence. Some evidence underlines the role of metabolic factors, pelvic ischemia, prostatic chronic inflammation and associated comorbidities in the pathophysiology of storage LUTS. A detailed evaluation of the severity of storage LUTS, and the concomitance of these symptoms with voiding and postmicturition symptoms, is mandatory for improving the diagnosis and personalizing treatment. A detailed medical history with comorbidities and associated risk factors, a physical examination, a comprehensive analysis of all the features of LUTS, including their impact on quality of life, and a frequency–volume chart (FVC) or bladder diary, are recommended for men with storage LUTS. Several drugs are available for the treatment of LUTS secondary to benign prostatic obstruction (BPO). Alpha-blockers (α-blockers), 5-α-reductase inhibitors and phosphodiesterase type 5 inhibitors are commonly used to manage storage LUTS occurring with voiding symptoms associated with BPO. Muscarinic receptor antagonists and Beta 3-agonists (β3-agonists) alone, or in combination with α-blockers, represent the gold standard of treatment in men with predominant storage LUTS. There is no specific recommendation regarding the best treatment options for storage LUTS after prostatic surgery. PMID:29434675

    Depression and anxiety disorders are highly comorbid, and share significant symptom overlap. Whereas depression has been consistently associated with excess mortality, the association between anxiety and mortality is less clear. Our aim was to identify constellations of anxious and depressive symptoms and examine their associations with mortality. This study considers respondents from the 1970 (n = 1203) and 1992 (n = 1402) cohorts of the Stirling County study. Symptoms of depression and anxiety were assessed using structured at-home interviews. Vital status of participants through 2011 was determined using probabilistic linkages to the Canadian Mortality Database. Exploratory factor analysis yielded three correlated factors in each cohort. Items loading on each factor varied slightly between cohorts, but roughly corresponded to (1) depressive symptoms, (2) anxious symptoms, and (3) somatic symptoms. The depressive factor was associated with increased risk of mortality in both the 1970 (HR: 1.35, 95% CI: 1.12, 1.62) and 1992 (HR: 1.25, 95% CI: 1.05, 1.48) cohorts. Anxious symptoms were associated with a reduced risk of mortality in the 1992 sample (HR: 0.72; 95% CI: 0.53, 0.90). Somatic symptoms were associated with a reduced risk of mortality in the 1970 sample (HR: 0.83, 95% CI: 0.69, 0.99), but an elevated risk of mortality in the 1992 sample (HR: 1.29; 95% CI: 1.11, 1.51). This study provides evidence that symptoms of depression and anxiety may have differential associations with early mortality. Somatic symptoms such as upset stomach and loss of appetite may be protective against mortality, perhaps through increased use of health care services. Conversely, symptoms such as weakness and cold sweats may be indicative of failing health. © 2018 Wiley Periodicals, Inc.

    to either subspecialist working alone. Does a subtotal surgical resection of a VS followed by stereotactic radiosurgery (SRS) to the residual tumor provide comparable hearing and FN preservation to patients who undergo a complete surgical resection? There is insufficient evidence to support subtotal resection (STR) followed by SRS provides comparable hearing and FN preservation to patients who undergo a complete surgical resection. Does surgical resection of VS treat preoperative balance problems more effectively than SRS? There is insufficient evidence to support either surgical resection or SRS for treatment of preoperative balance problems. Does surgical resection of VS treat preoperative trigeminal neuralgia more effectively than SRS? Level 3: Surgical resection of VSs may be used to better relieve symptoms of trigeminal neuralgia than SRS. Is surgical resection of VSs more difficult (associated with higher facial neuropathies and STR rates) after initial treatment with SRS? Level 3: If microsurgical resection is necessary after SRS, it is recommended that patients be counseled that there is an increased likelihood of a STR and decreased FN function.  The full guideline can be found at: https://www.cns.org/guidelines/guidelines-management-patients-vestibular-schwannoma/chapter_8.

    Mood and emotional disturbances are common in patients with stroke, and adversely affect the clinical outcome. We aimed to evaluate the efficacy of early administration of escitalopram to reduce moderate or severe depressive symptoms and improve emotional and neurological dysfunction in patients with stroke. This was a placebo controlled, double-blind trial done at 17 centres in South Korea. Patients who had had an acute stroke within the past 21 days were randomly assigned in a 1:1 ratio to receive oral escitalopram (10 mg/day) or placebo for 3 months. Randomisation was done with permuted blocks stratified by centre, via a web-based system. The primary endpoint was the frequency of moderate or severe depressive symptoms (Montgomery-Åsberg Depression Rating Scale [MADRS] ≥16). Endpoints were assessed at 3 months after randomisation in the full analysis set (patients who took study medication and underwent assessment of primary endpoint after randomisation), in all patients who were enrolled and randomly assigned (intention to treat), and in all patients who completed the trial (per-protocol analysis). This trial is registered with ClinicalTrials.gov, number NCT01278498. Between Jan 27, 2011, and June 30, 2014, 478 patients were assigned to placebo (n=237) or escitalopram (n=241); 405 were included in the full analysis set (195 in the placebo group, 210 in the escitalopram group). The primary outcome did not differ by study group in the full analysis set (25 [13%] patients in the placebo group vs 27 [13%] in the escitalopram group; odds ratio [OR] 1·00, 95% CI 0·56-1·80; p>0·99) or in the intention-to-treat analysis (34 [14%] vs 35 [15%]; OR 1·01, 95% CI 0·61-1·69, p=0·96). The study medication was generally well tolerated; the most common adverse events were constipation (14 [6%] patients who received placebo vs 14 [6%] who received escitalopram), muscle pain (16 [7%] vs ten [4%]), and insomnia (12 [5%] vs 12 [5%]).

    HaNDL syndrome (transient headache and neurological deficits with cerebrospinal fluid lymphocytosis) is characterised by one or more episodes of headache and transient neurological deficits associated with cerebrospinal fluid lymphocytosis. To date, few cases of HaNDL manifesting with confusional symptoms have been described. Likewise, very few patients with HaNDL and confusional symptoms have been evaluated with transcranial Doppler ultrasound (TCD). TCD data from patients with focal involvement reveal changes consistent with vasomotor alterations. We present the case of a 42-year-old man who experienced headache and confusional symptoms and displayed pleocytosis, diffuse slow activity on EEG, increased blood flow velocity in both middle cerebral arteries on TCD, and single-photon emission computed tomography (SPECT) findings suggestive of diffuse involvement, especially in the left hemisphere. To our knowledge, this is the first description of a patient with HaNDL, confusional symptoms, diffuse slow activity on EEG, and increased blood flow velocity in TCD. Our findings suggest a relationship between cerebral vasomotor changes and the pathophysiology of HaNDL. TCD may be a useful tool for early diagnosis of HaNDL.

    Evaluation of the posterior fossa (PF) on 5-mm-thick helical CT images (current default) has improved diagnostic accuracy compared to 5-mm sequential CT images; however, 5-mm-thick images may not be ideal for PF pathology due to volume averaging of rapid changes in anatomy in the Z-direction. Therefore, we sought to determine if routine review of 1.25-mm-thin helical CT images has superior accuracy in screening for nontraumatic PF pathology. MRI proof of diagnosis was obtained within 6 h of helical CT acquisition for 90 consecutive ED patients with, and 88 without, posterior fossa lesions. Helical CT images were post-processed at 1.25 and 5-mm-axial slice thickness. Two neuroradiologists blinded to the clinical/MRI findings reviewed both image sets. Interobserver agreement and accuracy were rated using Kappa statistics and ROC analysis, respectively. Of the 90/178 (51 %) who were MR positive, 60/90 (66 %) had stroke and 30/90 (33 %) had other etiologies. There was excellent interobserver agreement (κ > 0.97) for both thick and thin slice assessments. The accuracy, sensitivity, and specificity for 1.25-mm images were 65, 44, and 84 %, respectively, and for 5-mm images were 67, 45, and 85 %, respectively. The diagnostic accuracy was not significantly different (p > 0.5). In this cohort of patients with nontraumatic neurological symptoms referred to the posterior fossa, 1.25-mm-thin slice CT reformatted images do not have superior accuracy compared to 5-mm-thick images. This information has implications on optimizing resource utilizations and efficiency in a busy emergency room. Review of 1.25-mm-thin images may help diagnostic accuracy only when review of 5-mm-thick images as current default is inconclusive.

  8. A Review of Current Evidence of Olmesartan Medoxomil Mimicking Symptoms of Celiac Disease.

    Sanford, Michele L; Nagel, Angela K

    2015-04-01

    Objective:To review the evidence of an association between olmesartan medoxomil and symptoms mimicking celiac disease.Data Sources:Literature was searched in PubMed (1965-November 2013) using the key words or MeSH terms olmesartan, enteropathy, celiac disease, sprue, and diarrhea. References from the Food and Drug Administration (FDA) and Dipiro's Pharmacotherapy eighth edition textbook were also reviewed.Data Synthesis:There have been recent implications of olmesartan medoxomil being linked to symptoms mimicking celiac disease. Investigators first identified the association in 22 patients who presented with presumed refractory celiac disease. Upon further evaluation, it was discovered that these symptoms improved when olmesartan was discontinued. In response to this report, additional case studies have been published. DeGaetani et al also further analyzed patients with seronegative villous atrophy from the Celiac Disease Center and found that olmesartan accounted for 22% of previously unclassified sprue cases. Conversely, the authors of the ROADMAP trial, which compared olmesartan to placebo, found no significant differences in the incidence of gastrointestinal adverse effects.Conclusions:There is growing evidence supporting the association between olmesartan and sprue-like symptoms; however, further research is warranted. These symptoms can be life threatening and clinicians should be aware of the potential association.

    To determine if transcutaneous electric nerve stimulation (TENS) is efficacious in the treatment of pain in neurologic disorders. We performed a systematic literature search of Medline and the Cochrane Library from inception to April 2009. There are conflicting reports of TENS compared to sham TENS in the treatment of chronic low back pain, with 2 Class II studies showing benefit, but 2 Class I studies and another Class II study not showing benefit. Because the Class I studies are stronger evidence, TENS is established as ineffective for the treatment of chronic low back pain (2 Class I studies). TENS is probably effective in treating painful diabetic neuropathy (2 Class II studies). Transcutaneous electric nerve stimulation (TENS) is not recommended for the treatment of chronic low back pain (Level A). TENS should be considered in the treatment of painful diabetic neuropathy (Level B). Further research into the mechanism of action of TENS is needed, as well as more rigorous studies for determination of efficacy.

    Despite both having some shared features, evidence linking psychosis and adult attention deficit hyperactivity disorder (ADHD) is sparse and inconsistent. Hypotheses tested were (1) adult ADHD symptoms are associated with auditory hallucinations, paranoid ideation and psychosis (2) links between ADHD symptoms and psychosis are mediated by prescribed ADHD medications, use of illicit drugs, and dysphoric mood. The Adult Psychiatric Morbidity Survey 2007 (N=7403) provided data for regression and multiple mediation analyses. ADHD symptoms were coded from the ADHD Self-Report Scale (ASRS). Higher ASRS total score was significantly associated with psychosis, paranoid ideation and auditory hallucinations despite controlling for socio-demographic variables, verbal IQ, autism spectrum disorder traits, childhood conduct problems, hypomanic and dysphoric mood. An ASRS score indicating probable ADHD diagnosis was also significantly associated with psychosis. The link between higher ADHD symptoms and psychosis, paranoia and auditory hallucinations was significantly mediated by dysphoric mood, but not by use of amphetamine, cocaine or cannabis. In conclusion, higher levels of adult ADHD symptoms and psychosis are linked and dysphoric mood may form part of the mechanism. Our analyses contradict the traditional clinical view that the main explanation for people with ADHD symptoms developing psychosis is illicit drugs. Copyright © 2015 Elsevier Ireland Ltd.

The largest part of Freud's 125 French medical books up to 1900 (of 3,725 books overall) are devoted to hysteria and hypnotism, published mainly between 1885 and 1895. Over one-third (50) of the neurology (94) and alienism (22) books have Charcot or one of his direct pupils (Janet, Féré, Babinski, Gilles de la Tourette, Richer, Pitres, Sollier, Raymond, Marie, Binet, Ball, Bourneville, Blocq, Berbez, Guinon, and Souques) as author. During that period, Freud evolved from the clinical-anatomic method (after mainly experimental histologic studies) to theoretical neurology (using hysteria and aphasia models) and psychology, a process which subsequently led to the birth of psychoanalysis. The library of Freud gives an interesting account on his own evolving thinking, which led him to leave neurology for psychology and psychoanalysis.

    treatment approaches, such as cognitive-behavioral, rehabilitative, or psychodynamic therapy. Suggestions are generally symptom-focused (designed to resolve a symptom) or exploratory (using methods such as revivification or age regression to explore experiences associated with symptom onset). The evidence base is dominated by case studies and series, with a paucity of randomized controlled trials. Future evaluation studies should allow for the fact that suggestion with or without hypnosis is a component of broader treatment interventions adapted to a wide range of symptoms and presentations. An important role of the concept of suggestion in the management of functional neurologic symptoms is to raise awareness of how interactions with clinicians and wider clinical contexts can alter expectancies and beliefs of patients in ways that influence the onset, course, and remission of symptoms. © 2016 Elsevier B.V.

    Full Text Available BACKGROUND AND AIMS: Snake bite is an important cause of mortality and morbidity in certain parts of Sri Lanka. This study was designed to determine the offending snakes, neurological manifestations, disease course, and outcome in neurotoxic envenomation. METHODS AND MATERIAL: Fifty six consecutive patients admitted with neurological manifestations following snake bite were studied prospectively. Data were obtained regarding the offending snakes, neurological symptoms, time taken for onset of symptoms, neurological signs, and time taken for recovery. RESULTS: The offending snake was Russell′s viper in 27(48.2%, common and Sri Lankan krait in 19(33.9%, cobra in 3(5.4%, and unidentified in 7(12.5%. Ptosis was the commonest neurological manifestation seen in 48(85.7% followed by ophthalmoplegia (75%, limb weakness (26.8%, respiratory failure (17.9%, palatal weakness (10.7%, neck muscle weakness (7.1%, and delayed sensory neuropathy (1.8%. Neurological symptoms were experienced usually within 6 hours after the bite. Following administration of antivenom, the signs of recovery became evident within a few hours to several days. The duration for complete recovery ranged from four hours to two weeks. CONCLUSIONS: Complete recovery of neuromuscular weakness was observed in all patients except for one who died with intracerebral haemorrhage shortly after admission.

    Asia is important as it accounts for more than half of the world population. The majority of Asian countries fall into the middle income category. As for cultural traditions, Asia is highly varied, with many languages spoken. The pattern of neurologic diseases in Asia is largely similar to the West, with some disease features being specific to Asia. Whereas Asia constitutes 60% of the world's population, it contains only 20% of the world's neurologists. This disparity is particularly evident in South and South East Asia. As for neurologic care, it is highly variable depending on whether it is an urban or rural setting, the level of economic development, and the system of health care financing. To help remedy the shortage of neurologists, most counties with larger populations have established training programs in neurology. These programs are diverse, with many areas of concern. There are regional organizations serving as a vehicle for networking in neurology and various subspecialties, as well as an official journal (Neurology Asia). The Asian Epilepsy Academy, with its emphasis on workshops in various locations, EEG certification examination, and fellowships, may provide a template of effective regional networking for improving neurology care in the region. © 2015 American Academy of Neurology.

    Full Text Available There is a distinct shift of emphasis in clinical neurology in the last few decades. A few years ago, it was just sufficient for a clinician to precisely record history, document signs, establish diagnosis and write prescription. In the present context, there has been a significant intrusion of scientific culture in clinical practice. Several criteria have been proposed, refined and redefined to ascertain accurate diagnosis for many neurological disorders. Introduction of the concept of impairment, disability, handicap and quality of life has added new dimension to the measurement of health and disease and neurological disorders are no exception. "Best guess" treatment modalities are no more accepted and evidence based medicine has become an integral component of medical care. Traditional treatments need validation and new therapies require vigorous trials. Thus, proper quantification in neurology has become essential, both in practice and research methodology in neurology. While this aspect is widely acknowledged, there is a limited access to a comprehensive document pertaining to measurements in neurology. This following description is a critical appraisal of various measurements and also provides certain commonly used rating scales/scores in neurological practice.

    Full Text Available Abstract Background Management of cancer treatment-related symptoms is an important safety issue given that symptoms can become life-threatening and often occur when patients are at home. With funding from the Canadian Partnership Against Cancer, a pan-Canadian steering committee was established with representation from eight provinces to develop symptom protocols using a rigorous methodology (CAN-IMPLEMENT©. Each protocol is based on a systematic review of the literature to identify relevant clinical practice guidelines. Protocols were validated by cancer nurses from across Canada. The aim of this study is to build an effective and sustainable approach for implementing evidence-informed protocols for nurses to use when providing remote symptom assessment, triage, and guidance in self-management for patients experiencing symptoms while undergoing cancer treatments. Methods A prospective mixed-methods study design will be used. Guided by the Knowledge to Action Framework, the study will involve (a establishing an advisory knowledge user team in each of three targeted settings; (b assessing factors influencing nurses’ use of protocols using interviews/focus groups and a standardized survey instrument; (c adapting protocols for local use, ensuring fidelity of the content; (d selecting intervention strategies to overcome known barriers and implementing the protocols; (e conducting think-aloud usability testing; (f evaluating protocol use and outcomes by conducting an audit of 100 randomly selected charts at each of the three settings; and (g assessing satisfaction with remote support using symptom protocols and change in nurses’ barriers to use using survey instruments. The primary outcome is sustained use of the protocols, defined as use in 75% of the calls. Descriptive analysis will be conducted for the barriers, use of protocols, and chart audit outcomes. Content analysis will be conducted on interviews/focus groups and usability testing

    The aim of the paper is to show the various neurological and psychiatric symptoms in coeliac disease (CD). CD is a T cell-mediated, tissue-specific autoimmune disease which affects genetically susceptible individuals after dietary exposure to proline- and glutamine-rich proteins contained in certain cereal grains. Genetics, environmental factors and different immune systems, together with the presence of auto-antigens, are taken into account when identifying the pathogenesis of CD. CD pathogenesis is related to immune dysregulation, which involves the gastrointestinal system, and the extra-intestinal systems such as the nervous system, whose neurological symptoms are evidenced in CD patients. A gluten-free diet (GFD) could avoid cerebellar ataxia, epilepsy, neuropathies, migraine and mild cognitive impairment. Furthermore, untreated CD patients have more symptoms and psychiatric co-morbidities than those treated with a GFD. Common psychiatric symptoms in untreated CD adult patients include depression, apathy, anxiety, and irritability and schizophrenia is also common in untreated CD. Several studies show improvement in psychiatric symptoms after the start of a GFD. The present review discusses the state of the art regarding neurological and psychiatric complications in CD and highlights the evidence supporting a role for GFD in reducing neurological and psychiatric complications.

    Full Text Available The difficult types of preeclampsia and eclampsia are presented with the neurological symptoms. The break of cerebral autoregulation mechanism plays the most important role in pathogenesis of cerebral vasospasm. Nevertheless eclampsia isn’t just an ordinary hypertensive encephalopathy because other pathogenic mechanisms are involved in its appearance. The main neuropathologic changes are multifocal vasogenic edema, perivascular multiple microinfarctions and petechial hemorrhages. Neurological clinical manifestations are convulsions, headache, visual disturbances and rarely other discrete focal neurological symptoms. Eclampsia is a high-risk factor for onset of hemorrhagic or ischemic stroke. This is a reason why neurological diagnostic tests are sometimes needed. The method of choice for evaluation of complicated eclampsia is computerized brain topography that shows multiple areas of hypodensity in occipitoparietal regions. These changes are focal vasogenic cerebral edema. For differential diagnosis of eclampsia and stroke other diagnostic methods can be used - fundoscopic exam, magnetic resonance brain imaging, cerebral angiography and cerebrospinal fluid exam. The therapy of eclampsia considers using of magnesium sulfate, antihypertensive, anticonvulsive and antiedematous drugs.

    Full Text Available BackgroundDepressed populations demonstrate a greater tendency to have negative interpretations on ambiguous situations. Cognitive theories concerning depression proposed that such a negative bias plays an important role in developing and maintaining depression. There is now fairly consistent evidence arising from different stimuli and assessment methods that depression is featured by such a bias. The current study aimed to explore the neural signatures associated with the interpretation bias in the elderly with depressive symptoms confronted with different facial expressions using event-related brain potentials (ERPs.MethodsParticipants were 14 community-dwelling older adults with depressive symptoms assessed by the Center for Epidemiologic Studies Depression scale scores. We collected event-related potentials of their brain compared to that of 14 healthy aged-matched adults. The late positive potential (LPP was used to examine cognitive-affective processes associated with judgment of emotional facial expressions between the two groups.ResultsOld adults with depressive symptoms have much smaller amplitude than healthy older adults irrespective of the prime types. When processing the targets, the two groups showed different patterns regarding the LPP. The healthy control group revealed no differences between ambiguous and happy primes, irrespective of whether the targets were sad or happy facial expressions. However, significant differences were found between happy and sad and between ambiguous and sad primes. Such a pattern indicates a positive bias in healthy elderly adults. Regarding the elderly with depressive symptoms, there were no significant differences between ambiguous versus happy, ambiguous versus sad primes, and happy versus sad primes. Concerning reaction times, there was no group difference. Thus, the findings provide some support for cognitive theories of depression.ConclusionThe current study shows that there is an association

    Attention-deficit/hyperactivity disorder (ADHD) symptoms and mathematics ability are associated, but little is known about the genetic and environmental influences underlying this association. Data came from more than 6,000 twelve-year-old twin pairs from the UK population-representative Twins Early Development Study. Parents rated each twin's behaviour using a DSM-IV-based 18-item questionnaire of inattentive and hyperactive-impulsive ADHD symptoms. Mathematics tests based on the UK National Curriculum were completed by each twin. The twins also completed standardised tests of reading and general cognitive ability. Multivariate twin model fitting was applied. Inattentive and hyperactive-impulsive ADHD symptoms were highly heritable (67% and 73% respectively). Mathematics ability was moderately heritable (46%). Mathematics ability and inattentiveness showed a significantly greater phenotypic correlation (r(p) = -.26) and genetic correlation (r(A) = -.41) than mathematics ability and hyperactivity-impulsivity (r(p) = -.18; r(A) = -.22). The genetic correlation between inattentiveness and mathematics ability was largely independent from hyperactivity-impulsivity, and was only partially accounted for by genetic influences related to reading and general cognitive ability. Results revealed the novel finding that mathematics ability shows significantly stronger phenotypic and genetic associations with inattentiveness than with hyperactivity-impulsivity. Genetic associations between inattentiveness and mathematics ability could only partially be accounted for by hyperactivity-impulsivity, reading and general cognitive ability. Results suggest that mathematics ability is associated with ADHD symptoms largely because it shares genetic risk factors with inattentiveness, and provide further evidence for considering inattentiveness and hyperactivity-impulsivity separately. DNA markers for ADHD symptoms (especially inattentiveness) may also be candidate risk factors for

    In an attempt to elucidate risk factors for developing cerebral embolism (CE) in patients with heart disease, hemodynamic, sonographic or radiologic, and neurologic manifestations of heart disease developing into CE were retrospectively analyzed in 44 patients with CE and 122 patients with mitral valve disease (MVD). The most common underlying disease of CE was valve disease (50 %), followed by myocardial infarction, atrial fibrillation, and infectious endocarditis. In MVD patients, risk factors for CE were considered to be atrial fibrillation, mitral stenosis, and intraatrial thrombi. Combined use of various imaging modalities revealed the presence of intraatrial thrombi in 65 % of the CE patients. Cranial computed tomography showed hemorrhagic infarction in 22 %, and found the mid-arotic artery to be the commonest responsible region (81 %). The frequent initial neurologic symptom was hemiplegia. Half of the patients had disturbance of consciousness on admission. Prognosis was better in patients with MVD than those with the other types of heart disease. (Namekawa, K.). 117 refs.

    Incidence of depression increases markedly around age 13 years, and nearly three-quarters of adults report that their mental health problems started in adolescence. Although maternal depression is a risk factor for adolescent depression, evidence about the association between paternal and adolescent depression is inconclusive, and many studies have methodological limitations. We aimed to assess the association between paternal and adolescent depressive symptoms in two large population-based cohort studies. We used data for two-parent families from two representative prospective cohorts in Ireland (Growing up in Ireland [GUI]) and the UK (Millennium Cohort Study [MCS]). Parental depressive symptoms were measured with the Centre for Epidemiological Studies Depression Scale in the GUI cohort when children were 9 years old, and the Kessler six-item psychological distress scale in the MCS cohort when children were 7 years old. Adolescent depressive symptoms were measured with the Short Mood and Feelings Questionnaire (SMFQ) at age 13 years in the GUI cohort and age 14 years in the MCS cohort. We analysed data using linear regression models, before and after adjustment for confounders, in both multiply imputed and complete case samples. There were 6070 families in GUI and 7768 in MCS. After all adjustments, a 1 SD (three-point) increase in paternal depressive symptoms was associated with an increase of 0·24 SMFQ points (95% CI 0·03-0·45; p=0·023) in the GUI cohort and 0·18 SMFQ points (0·01-0·36; p=0·041) in the MCS cohort. This association was independent of, and not different in magnitude to, the association between maternal and adolescent depressive symptoms (Wald test p=0·435 in the GUI cohort and 0·470 in the MCS cohort). Our results show an association between depressive symptoms in fathers and depressive symptoms in their adolescent offspring. These findings support the involvement of fathers as well as mothers in early interventions to reduce the

    There is significant variation in the expression of schizophrenia across ethnically different populations, and the optimal structural and diagnostic representation of schizophrenia are contested. We contrasted both lifetime frequencies of DSM-IV criterion A (the core symptom criterion of the internationally recognized DSM classification system) symptoms and types/content of delusions and hallucinations in transethnic schizophrenia populations from Australia (n = 776), India (n = 504) and Sarawak, Malaysia (n = 259), to elucidate clinical heterogeneity. Differences in both criterion A symptom composition and symptom content were apparent. Indian individuals with schizophrenia reported negative symptoms more frequently than other sites, whereas individuals from Sarawak reported disorganized symptoms more frequently. Delusions of control and thought broadcast, insertion, or withdrawal were less frequent in Sarawak than Australia. Curiously, a subgroup of 20 Indian individuals with schizophrenia reported no lifetime delusions or hallucinations. These findings potentially challenge the long-held view in psychiatry that schizophrenia is fundamentally similar across cultural groups, with differences in only the content of psychotic symptoms, but equivalence in structural form.

    Theoretical and clinical publications suggest the existence of cultural differences in the expression and experience of depression. Measurement non-equivalence remains a potential methodological explanation for the lower prevalence of depression among Asian Americans compared to European Americans. This study compared DSM-IV depressive symptoms among Asian Americans and European Americans using secondary data analysis of the Collaborative Psychiatric Epidemiology Surveys (CPES). The Composite International Diagnostic Interview (CIDI) was used for the assessment of depressive symptoms. Of the entire sample, 310 Asian Americans and 1974 European Americans reported depressive symptoms and were included in the analyses. Measurement variance was examined with an item response theory differential item functioning (IRT DIF) analysis. χ2 analyses indicated that, compared to Asian Americans, European American participants more frequently endorsed affective symptoms such as 'feeling depressed', 'feeling discouraged' and 'cried more often'. The IRT analysis detected DIF for four out of the 15 depression symptom items. At equal levels of depression, Asian Americans endorsed feeling worthless and appetite changes more easily than European Americans, and European Americans endorsed feeling nervous and crying more often than Asian Americans. Asian Americans did not seem to over-report somatic symptoms; however, European Americans seemed to report more affective symptoms than Asian Americans. The results suggest that there was measurement variance in a few of the depression items.

    Diet, fluid intake and caffeine, alcohol and tobacco use may have effects on lower urinary tract symptoms. Constructive changes in these modifiable nonurological factors are suggested to improve lower urinary tract symptoms. To better understand the relationship between nonurological factors and lower urinary tract symptoms, we performed a systematic literature review to examine, grade and summarize reported associations between lower urinary tract symptoms and diet, fluid intake and caffeine, tobacco and alcohol use. We performed PubMed® searches for eligible articles providing evidence on associations between 1 or more nonurological factors and lower urinary tract symptoms. A modified Oxford scale was used to grade the evidence. We reviewed 111 articles addressing diet (28 studies), fluid intake (21) and caffeine (21), alcohol (26) and tobacco use (44). The evidence grade was generally low (6% level 1, 24% level 2, 11% level 3 and 59% level 4). Fluid intake and caffeine use were associated with urinary frequency and urgency in men and women. Modest alcohol use was associated with decreased likelihood of benign prostatic hyperplasia diagnosis and reduced lower urinary tract symptoms in men. Associations between lower urinary tract symptoms and ingestion of certain foods and tobacco were inconsistent. Evidence of associations between lower urinary tract symptoms and diet, fluid intake and caffeine, alcohol and tobacco use is sparse and mostly observational. However, there is evidence of associations between increased fluid and caffeine intake and urinary frequency/urgency, and between modest alcohol intake and decreased benign prostatic hyperplasia diagnosis and lower urinary tract symptoms. Given the importance of these nonurological factors in daily life, and their perceived impact on lower urinary tract symptoms, higher quality evidence is needed.

    Negative information processing biases have been hypothesised to serve as precursors for the development of depression. The current study examined negative self-referent information processing and depressive symptoms in a community sample of adolescents (N = 291, Mage at baseline = 12.34 ± 0.61, 53% female, 47.4% African-American, 49.5% Caucasian and 3.1% Biracial). Participants completed a computerised self-referent encoding task (SRET) and a measure of depressive symptoms at baseline and completed an additional measure of depressive symptoms nine months later. Several negative information processing biases on the SRET were associated with concurrent depressive symptoms and predicted increases in depressive symptoms at follow-up. Findings partially support the hypothesis that negative information processing biases are associated with depressive symptoms in a nonclinical sample of adolescents, and provide preliminary evidence that these biases prospectively predict increases in depressive symptoms.

    The use of dietary supplements for treating a wide range of health conditions has grown rapidly in the United States. In the field of men's health, the most common dietary supplement used is an extract of the berry of the saw palmetto plant, with which men commonly self-medicate in order to treat lower urinary tract symptoms. Throughout the past two decades, substantial literature has emerged examining the biologic and clinical effects of saw palmetto extracts. Several lines of evidence suggest that saw palmetto may exert physiologic effects consistent with a beneficial clinical effect on the mechanisms of benign prostatic hyperplasia. Although most clinical studies tend to suggest a modest efficacy benefit of saw palmetto, more recent studies are less consistent and the precise clinical value of saw palmetto for treating lower urinary tract symptoms remains undefined. Overall, there appear to be few safety concerns with short-term use of this herbal medicine, although large-scale and longer-term safety studies have not been performed. Higher-quality studies are currently underway to better define the potential benefits and risks of plant-based extracts for treating symptoms related to benign prostatic hyperplasia.

    The new concept of palliative care supports the idea of palliation as an early approach to patients affected by disabling and life-limiting disease which focuses on the patient's quality of life along the entire course of disease. This model moves beyond the traditional concept of palliation as an approach restricted to the final stage of disease and widens the fields of intervention. There is a growing awareness of the importance of palliative care not only in oncological diseases but also in many other branches of medicine, and it appears particularly evident in the approach to many of the most frequent neurological diseases that are chronic, incurable and autonomy-impairing illnesses. The definition and implementation of palliative goals and procedures in neurology must take into account the specific features of these conditions in terms of the complexity and variability of symptoms, clinical course, disability and prognosis. The realization of an effective palliative approach to neurological diseases requires specific skills and expertise to adapt the concept of palliation to the peculiarities of these diseases; this approach should be realized through the cooperation of different services and the action of a multidisciplinary team in which the neurologist should play a central role to identify and face the patient's needs. In this view, it is paramount for the neurologist to be trained in these issues to promote the integration of palliative care in the care of neurological patients.

    Palliative care is an approach to the care of patients and families facing progressive and chronic illnesses that focuses on the relief of suffering due to physical symptoms, psychosocial issues, and spiritual distress. As neurologists care for patients with chronic, progressive, life-limiting, and disabling conditions, it is important that they understand and learn to apply the principles of palliative medicine. In this article, we aim to provide a practical starting point in palliative medicine for neurologists by answering the following questions: (1) What is palliative care and what is hospice care? (2) What are the palliative care needs of neurology patients? (3) Do neurology patients have unique palliative care needs? and (4) How can palliative care be integrated into neurology practice? We cover several fundamental palliative care skills relevant to neurologists, including communication of bad news, symptom assessment and management, advance care planning, caregiver assessment, and appropriate referral to hospice and other palliative care services. We conclude by suggesting areas for future educational efforts and research. PMID:24991027

    Aortic manipulation and particle embolization have been identified to cause cerebrovascular accidents in cardiac surgery. Recent data suggest that left-hemispheric cerebrovascular accident (right-sided symptoms) is more common, and this has been interpreted as being caused by aortic cannula stream jets. Our aim was to evaluate symptoms of cerebrovascular accident and side differences from a retrospective statistical analysis. During a 2-year period, 2641 consecutive cardiac surgery cases were analyzed. Patients positive for cerebrovascular accident were extracted from a database designed to monitor clinical symptoms. A protocol was used to confirm symptom data with the correct diagnosis in patient records. Patients were subdivided into 3 groups: control, immediate cerebrovascular accident, and delayed cerebrovascular accident. Among pooled patients, immediate and delayed cerebrovascular accidents were 3.0% and 0.9%, respectively. The expected predisposing factors behind immediate cerebrovascular accidents were significant, although the type of operation affected this search. Aortic quality was a strong predictor ( P cerebrovascular accident was unaffected by surgery group. Left-sided symptoms of immediate cerebrovascular accident were approximately twice as frequent ( P = .016) as on the contralateral side. This phenomenon was observed for pooled patients and for isolated coronary bypass procedures (n = 1882; P = .025). Immediate cerebrovascular accident and aortic calcifications are linked. The predominance of left-sided symptoms may suggest that aortic manipulation and anatomic mechanisms in the aortic arch are more likely to cause cerebrovascular accidents than effects from cannula stream jets.

    Somatization syndromes were defined in a sample of 102 psychosomatic inpatients according to the restrictive criteria of DSM-III-R somatization disorder and the broader diagnostic concept of the Somatic Symptom Index (SSI). Both groups showed a qualitatively similar pattern of psychopathological comorbidity and had elevated scores on measures of depression, hypochondriasis, and anxiety. A good discrimination between mild and severe forms of somatization was found by using the SSI criterion. SSI use accounted for a substantial amount of comorbidity variance, with rates of 15%-20% for depression, 16% for hypochondriasis, and 13% for anxiety. The results provide further evidence for the validity of the SSI concept, which reflects the clinical relevance of somatization in addition to the narrow definition of somatization disorder.

    This chapter aims to provide an up-to-date review of the science and clinical practice pertaining to neurologic injury after successful cardiopulmonary resuscitation. The past two decades have seen a major shift in the science and practice of cardiopulmonary resuscitation, with a major emphasis on postresuscitation neurologic care. This chapter provides a nuanced and thoughtful historic and bench-to-bedside overview of the neurologic aspects of cardiopulmonary resuscitation. A particular emphasis is made on the anatomy and pathophysiology of hypoxic-ischemic encephalopathy, up-to-date management of survivors of cardiopulmonary resuscitation, and a careful discussion on neurologic outcome prediction. Guidance to practice evidence-based clinical care when able and thoughtful, pragmatic suggestions for care where evidence is lacking are also provided. This chapter serves as both a useful clinical guide and an updated, thorough, and state-of-the-art reference on the topic for advanced students and experienced practitioners in the field. © 2017 Elsevier B.V.

    Full Text Available Dengue infection is highly endemic in many tropical countries including Malaysia. However, neurological complications arising from dengue infection is not common; Gullain–Barre syndrome (GBS is one of these infrequent complications. In this paper, we have reported a case in which a 39-year-old woman presented with a neurological complication of dengue infection without typical symptoms and signs of dengue fever. She had a history of acute gastroenteritis (AGE followed by an upper respiratory tract infection (URTI weeks prior to her presentation rendering GBS secondary to the post viral URTI and AGE as the most likely diagnosis. Presence of thrombocytopenia was the only clue for dengue in this case.

    To develop evidence-based recommendations for complementary and alternative medicine (CAM) in multiple sclerosis (MS). We searched the literature (1970-March 2011; March 2011-September 2013 MEDLINE search), classified articles, and linked recommendations to evidence. Clinicians might offer oral cannabis extract for spasticity symptoms and pain (excluding central neuropathic pain) (Level A). Clinicians might offer tetrahydrocannabinol for spasticity symptoms and pain (excluding central neuropathic pain) (Level B). Clinicians should counsel patients that these agents are probably ineffective for objective spasticity (short-term)/tremor (Level B) and possibly effective for spasticity and pain (long-term) (Level C). Clinicians might offer Sativex oromucosal cannabinoid spray (nabiximols) for spasticity symptoms, pain, and urinary frequency (Level B). Clinicians should counsel patients that these agents are probably ineffective for objective spasticity/urinary incontinence (Level B). Clinicians might choose not to offer these agents for tremor (Level C). Clinicians might counsel patients that magnetic therapy is probably effective for fatigue and probably ineffective for depression (Level B); fish oil is probably ineffective for relapses, disability, fatigue, MRI lesions, and quality of life (QOL) (Level B); ginkgo biloba is ineffective for cognition (Level A) and possibly effective for fatigue (Level C); reflexology is possibly effective for paresthesia (Level C); Cari Loder regimen is possibly ineffective for disability, symptoms, depression, and fatigue (Level C); and bee sting therapy is possibly ineffective for relapses, disability, fatigue, lesion burden/volume, and health-related QOL (Level C). Cannabinoids may cause adverse effects. Clinicians should exercise caution regarding standardized vs nonstandardized cannabis extracts and overall CAM quality control/nonregulation. Safety/efficacy of other CAM/CAM interaction with MS disease-modifying therapies is unknown.

    Vestibular schwannomas (VS) are uncommon lesions that are a substantial challenge to the neurosurgeons, otologists, and radiation oncologists who undertake their clinical management. A starting point to improving the current knowledge is to define the benchmarks of the current research studying VS management using evidence-based techniques in order to allow meaningful points of departure for future scientific and clinical research. To establish the best evidence-based management of VS, including initial otologic evaluation, imaging diagnosis, use of surgical techniques, assessment of tumor pathology, and the administration of radiation therapy. Multidisciplinary writing groups were identified to design questions, literature searches, and collection and classification of relevant findings. This information was then translated to recommendations based on the strength of the available literature. This guideline series yielded some level 2 recommendations and a greater number of level 3 recommendations directed at the management of VS. Importantly, in some cases, a number of well-designed questions and subsequent searches did not yield information that allowed creation of a meaningful and justifiable recommendation. This series of guidelines was constructed to assess the most current and clinically relevant evidence for the management of VS. They set a benchmark regarding the current evidence base for this type of tumor while also highlighting important key areas for future basic and clinical research, particularly on those topics for which no recommendations could be formulated.  The full guidelines can be found at: https://www.cns.org/guidelines/guidelines-management-patients-vestibular-schwannoma.

    2012-11-27

    To review evidence published since the 2001 American Academy of Neurology (AAN) practice parameter regarding the effectiveness, safety, and tolerability of steroids and antiviral agents for Bell palsy. We searched Medline and the Cochrane Database of Controlled Clinical Trials for studies published since January 2000 that compared facial functional outcomes in patients with Bell palsy receiving steroids/antivirals with patients not receiving these medications. We graded each study (Class I-IV) using the AAN therapeutic classification of evidence scheme. We compared the proportion of patients recovering facial function in the treated group with the proportion of patients recovering facial function in the control group. Nine studies published since June 2000 on patients with Bell palsy receiving steroids/antiviral agents were identified. Two of these studies were rated Class I because of high methodologic quality. For patients with new-onset Bell palsy, steroids are highly likely to be effective and should be offered to increase the probability of recovery of facial nerve function (2 Class I studies, Level A) (risk difference 12.8%-15%). For patients with new-onset Bell palsy, antiviral agents in combination with steroids do not increase the probability of facial functional recovery by >7%. Because of the possibility of a modest increase in recovery, patients might be offered antivirals (in addition to steroids) (Level C). Patients offered antivirals should be counseled that a benefit from antivirals has not been established, and, if there is a benefit, it is likely that it is modest at best.

    . Neurological symptoms, such as burning sensations (occasionally accompanied by acroparesthesia) and stroke, are among the first to appear, and occur in both male and female patients. A delay in establishing the diagnosis of Fabry's disease can cause unnecessary problems, especially now that enzyme replacement...... treatment is available to prevent irreversible organ damage. Females with Fabry's disease who present with pain have often been ignored and misdiagnosed because of the disorder's X-linked inheritance. This Review will stress the importance of recognizing neurological symptoms for the diagnosis of Fabry...

    The bilateral vagus nerves (Cranial X) provide both afferent and efferent connections between the viscera and the caudal medulla. The afferent branches increasingly are being recognized as providing significant input to the central nervous system for modulation of complex behaviors. In this paper, we review evidence from our laboratory that increases in vagal afferent activity are involved in perpetuating binge-eating and vomiting in bulimia nervosa. Preliminary findings are also presented which suggest that a subgroup of depressions may have a similar pathophysiology. Two main approaches were used to study the role of vagal afferents. Ondansetron (ONDAN), a 5-HT3 antagonist, was used as a pharmacological tool for inhibiting or reducing vagal afferent neurotransmission. Second, somatic pain detection thresholds were assessed for monitoring a physiological process known to be modulated by vagal afferents, including the gastric branches involved in meal termination and satiety. High levels of vagal activity result in an increase in pain detection thresholds. Depressive symptoms were assessed using the Beck Depression Inventory (BDI). Positron Emission Tomography (PET) was used to identify higher cortical brain areas activated by vagal stimulation produced by proximal gastric distention in normal eating subjects. Double-blind treatment of severe bulimia nervosa subjects with ONDAN resulted in a rapid and significant decrease in binge-eating and vomiting compared to placebo controls. The decrease in abnormal eating episodes was accompanied by a return of normal satiety. Pain detection thresholds measured weekly over the course of the treatment protocol were found to dynamically fluctuate in association with bulimic episodes. Thresholds were the most elevated during periods of short-term abstinence from the behaviors, suggesting that not engaging in a binge/vomit episode is accompanied by an increase in vagal activity. ONDAN also resulted in abolition of the

    Elevated peripheral proline is associated with psychiatric disorders, and there is evidence that proline is a neuromodulator. The proline dehydrogenase (PRODH) gene, which encodes the enzyme that catalyzes proline catabolism, maps to human chromosome 22q11.2, a region conferring risk of schizophrenia. In the Prodh-null mouse, an interaction between elevated peripheral proline and another 22q11.2 gene, catechol-O-methyltransferase (COMT), on neurotransmission and behavior has been reported. We explored the relationship between fasting plasma proline levels and COMT Val(158)Met genotype on symptoms (positive, negative and total) in schizophrenia patients. In an exploratory study we also examined symptom change in patients with bipolar disorder. There was a significant interaction between peripheral proline and COMT on negative symptoms in schizophrenia (PScale for the Assessment of Negative Symptom (SANS) scores. In contrast, high proline was associated with high SANS scores in patients carrying a Met allele. The relationship between proline and COMT also appears to modify negative symptoms across psychiatric illness. In bipolar disorder, a significant interaction was also observed on negative-symptom change (P=0.007, n=43). Negative symptoms are intractable and largely unaddressed by current medications. These data indicate a significant interaction between peripheral proline and COMT genotype, influencing negative symptoms in schizophrenia and bipolar disorder. That high proline has converse effects on symptoms by COMT genotype, may have implications for therapeutic decisions.

    2010-02-01

    This review presents the past and the present of pediatric neurology in Poland. Pediatric neurology has its roots in Polish general neurology represented by many outstanding scientists. The founder of Polish school of neurology at the end of 19th century was Edward Flatau, known as the author of Flatau's law. The most famous Polish neurologist was Joseph Babiński, recognized for the first description of pathological plantar reflex. First Polish publication related to child neurology was Brudziński's report on a new meningeal symptom (the flexion of lower limbs during passive neck flexion with pain in neck). Contemporary child neurology in Poland was created by Professor Zofia Majewska after the Second World War. Now 10 academic centers of child neurology exist in Poland fulfilling educational, scientific, and therapeutic roles. Polish Society of Child Neurology was established in 1991 and now there are about 580 members, including 300 child neurologists.

    A 49-year-old man presented with a 30-year history of oral and genital aphthous ulcers and joint pain. One day before his admission he developed double vision and weakness in the right extremities. Neurological examination revealed right 5th nerve palsy, left 6th to 18th nerve palsy, left Horner's sign, and motor and sensory impairment in the right upper and lower extremities. X-ray CT showed diffuse, weak, low-density areas in the brainstem. T1 weighted images showed low signals in the left side of the mid-pons, the left tegmentum and the right basis of the upper pons, and the left tegmentum of the midbrain. T2 weighted images showed high signals in the whole pons and the left side of the midbrain. MRI allowed the differentiation of reversible lesions, such as brain edema, and irreversible lesions, such as necrosis and demyelination of the tissue. (Namekawa, K.).

    To develop recommendations for the evaluation, diagnosis, prognostication, and treatment of facioscapulohumeral muscular dystrophy (FSHD) from a systematic review and analysis of the evidence. Relevant articles were analyzed in accordance with the American Academy of Neurology classification of evidence schemes for diagnostic, prognostic, and treatment studies. Recommendations were linked to the strength of the evidence and other factors. Available genetic testing for FSHD type 1 is highly sensitive and specific. Although respiratory insufficiency occurs rarely in FSHD, patients with severe FSHD should have routine pulmonary function testing. Routine cardiac screening is not necessary in patients with FSHD without cardiac symptoms. Symptomatic retinal vascular disease is very rare in FSHD. Exudative retinopathy, however, is potentially preventable, and patients with large deletions should be screened through dilated indirect ophthalmoscopy. The prevalence of clinically relevant hearing loss is not clear. In clinical practice, patients with childhood-onset FSHD may have significant hearing loss. Because undetected hearing loss may impair language development, screening through audiometry is recommended for such patients. Musculoskeletal pain is common in FSHD and treating physicians should routinely inquire about pain. There is at present no effective pharmacologic intervention in FSHD. Available studies suggest that scapular fixation is safe and effective. Surgical scapular fixation might be cautiously offered to selected patients. Aerobic exercise in FSHD appears to be safe and potentially beneficial. On the basis of the evidence, patients with FSHD might be encouraged to engage in low-intensity aerobic exercises. © 2015 American Academy of Neurology.

    The purpose of this study is to highlight the evidence of signs and symptoms of craniomandibular disorders (CMD) in patients suffering from fibromyalgia. The study has been carried out from May 2011 to May 2015, recruiting a sample of fibromyalgia patients at the Department of Neurophysiopathology at the hospital Policlinico in Bari. Among the 150 examined patients, 60 of them have been diagnosed to suffer from fibromyalgia and 27 accepted to be investigated with a gnathologic examination at the Dental School at the University of Bari. 24 patients (88.9%) were women and 3 (11.1%) men; from 26 to 66 years old (average age, 39). 14 patients (51.9%) were affected by primary fibromyalgia, the remaining 13 (48.1%) by secondary fibromyalgia, mainly associated with hypothyroidism (29.6%). VAS average score was about 8 ± 1.85. The frequency of pain was daily in 15 patients (55.6%); twice a week in 10 patients (37.03%) and a few times a month in 2 patients (7.4%). 11 patients (40.7%) attributed the onset of fibromyalgia to a specific instigating event. In addition, from the gnathologic anamnesis, 11 patients (40,7%) reported a painful symptom in the head-neck region, especially in the frontal region, in the neck, in the masseter muscle and ATM. VAS average score was 3.4 ± 2.8, significantly lower than the one referring to the fibromyalgia pain. The gnathological examination found CMD signs and symptoms in 18 patients (66.7%). Concerning the prevalence of CMD, in type I fibromyalgia, myofascial pain was more frequent (5 patients), whereas in type II fibromyalgia, what was more frequent was a dislocation with reduction (3 patients). Based on clinic experience, we can affirm that some patients with CMD report pain in other regions. It is difficult to distinguish the CMD forms directly correlated to fibromyalgia from those engendered by parafunctional activities; hence the need is to resolve the fibromyalgia syndrome adopting a multidisciplinary approach.

    Full Text Available OBJECTIVE: It was to report on Brazilian cases of neurological complications from bariatric surgery. The literature on the subject is scarce. METHOD: Cases attended by neurologists in eight different Brazilian cities were collected and described in the present study. RESULTS: Twenty-six cases were collected in this study. Axonal polyneuropathy was the most frequent neurological complication, but cases of central demyelination, Wernicke syndrome, optical neuritis, radiculits, meralgia paresthetica and compressive neuropathies were also identified. Twenty-one patients (80% had partial or no recovery from the neurological signs and symptoms. CONCLUSION: Bariatric surgery, a procedure that is continuously increasing in popularity, is not free of potential neurological complications that should be clearly presented to the individual undergoing this type of surgery. Although a clear cause-effect relation cannot be established for the present cases, the cumulative literature on the subject makes it important to warn the patient of the potential risks of this procedure.

    In 2011, a large outbreak of Shiga toxin-producing enterohemorrhagic Escherichia coli (EHEC) infections occurred in northern Germany, which mainly affected adults. Out of 3842 patients, 104 experienced a complicated course comprising hemolytic uremic syndrome and neurological complications, including cognitive impairment, aphasia, seizures and coma. T2 hyperintensities on magnet resonance imaging (MRI) bilateral in the thalami and in the dorsal pons were found suggestive of a metabolic toxic effect. Five of the 104 patients died because of toxic heart failure. In the present study, the post-mortem neuropathological findings of the five EHEC patients are described. Histological investigation of 13 brain regions (frontal, temporal, occipital cortex, corpora mammillaria, thalamus, frontal operculum, corona radiata, gyrus angularis, pons, medulla oblongata, cerebellar vermis and cerebellar hemisphere) showed no thrombosis, ischemic changes or fresh infarctions. Further, no changes were found in electron microscopy. In comparison with five age-matched controls, slightly increased activation of microglia and a higher neuronal expression of interleukin-1β and of Shiga toxin receptor CD77/globotriaosylceramide 3 was observed. The findings were confirmed by Western blot analyses. It is suggested that CD77/globotriaosylceramide upregulation may be a consequence to Shiga toxin exposure, whereas increased interleukin-1β expression may point to activation of inflammatory cascades. © 2014 International Society of Neuropathology.

    Attention deficit hyperactivity disorder (ADHD) relates to four dimensions of behavior: inattentiveness, restlessness, impulsiveness and hyperactivity. Symptoms affect multiple areas of daily life such as academic performance and social functioning. Despite the negative effects of ADHD, people diagnosed with ADHD do not necessarily regard themselves as being impaired. However, it is unclear how adults with ADHD experience and manage their symptoms. To identify and synthesize the best available evidence on how adults experience living with ADHD. Adults with confirmed ADHD diagnosis. How adults with ADHD experience and manage the symptoms of ADHD and links between protective factors provided by relatives, friends, fellow students, mentors and colleagues. Studies based on qualitative data, including, but not limited to, designs within phenomenology, grounded theory, content analysis or ethnography. A three-step search strategy identified published and unpublished qualitative studies from 1990 to July 2015. Studies meeting the inclusion criteria were independently assessed by two reviewers using the standardized critical appraisal instrument from the Joanna Briggs Institute Qualitative Assessment and Review Instrument (JBI-QARI). Data were extracted from 10 included studies using the JBI-QARI. Qualitative research findings were synthesized using the JBI-QARI. A total of 103 findings from 10 studies were aggregated into 16 categories that were meta-synthesized into four synthesized findings: "Adults are aware of being different from others and strive to be an integrated, accepted part of the community;" "Adults with ADHD are creative and inventive;" "Adults with ADHD develop coping strategies in striving for a healthy balance in life" and "For adults with ADHD, accomplishing and organizing tasks in everyday life is a challenge but it can also be rewarding." Adults with ADHD have problems stemming from ADHD symptoms in relation to interacting in social relationships

    Although depressive symptoms are common during adolescence, little research has examined gene-environment interaction on youth depression. This study chose the brain-derived neurotrophic factor (BDNF) gene, tested the interaction between a functional polymorphism resulting amino acid substitution of valine (Val) to methionine (Met) in the proBDNF protein at codon 66 (Val66Met), and maternal parenting on youth depressive symptoms in a sample of 780 community adolescents of Chinese Han ethnicity (aged 11-17, M = 13.6, 51.3 % females). Participants reported their depressive symptoms and perceived maternal parenting. Results indicated the BDNF Val66Met polymorphism significantly moderated the influence of maternal warmth-reasoning, but not harshness-hostility, on youth depressive symptoms. Confirmatory model evaluation indicated that the interaction effect involving warmth-reasoning conformed to the differential-susceptibility rather than diathesis-stress model of person-X-environment interaction. Thus, Val carriers experienced less depressive symptoms than Met homozygotes when mothering was more positive but more symptoms when mothering was less positive. The findings provided evidence in support of the differential susceptibility hypothesis of youth depressive symptoms and shed light on the importance of examining the gene-environment interaction from a developmental perspective.

    The study questions whether different types of somatization may be a core symptom of melancholia, thus, being invariable across cultures and being a candidate for neurobiological research and diagnostic criteria. 51 Turkish patients and 51 education-matched German patients with melancholic depression were compared for two types of somatization. Turkish patients had higher frequencies of somatic preoccupation and hypochondriasis but they were not different in the perception and experience of somatic symptoms. It is concluded that: (1) somatization has to be differentiated psychopathologically; (2) it may be a neurobiological core symptom of melancholia in the well-defined sense of 'perceiving abnormal somatic symptoms'; and (3) it may be a culture-bound symptom in the sense of 'being abnormally concerned with somatic symptoms or hypochondrial fears'.

    Controversy exists whether mood disorders, such as depression, are associated with Lyme borreliosis (LB). The study objective was to assess prevalence of depressive symptoms in subgroups of patients referred to a tertiary Lyme center, to investigate whether depressive symptoms can be used in clinical practice to discriminate for LB. This cohort study included adult patients who visited a tertiary Lyme center between January 2008 and December 2014. Prior to medical consultation, serum samples were taken and the Beck Depression Inventory II was completed to assess depressive symptoms. Lyme diagnosis was retrospectively extracted from the patient's medical record. Patients were classified based on clinical LB and serology results. Prevalence of moderate/severe depressive symptoms was calculated. Using logistic regression, odds ratios with 95% confidence intervals (CIs) were calculated for moderate/severe depressive symptoms. In total, 1454 patients were included. Prevalence of moderate/severe depressive symptoms was lowest in patients with no clinical LB and positive serology (15.3%), higher in patients with clinical LB with positive and negative serology (19.3% and 20.9% respectively), and highest in patients with no clinical LB and negative serology (29.3%). The odds ratio for moderate/severe depressive symptoms in patients with LB and positive serology was 0.71 (95% CI, .50-1.03) compared to patients with no LB and negative serology. The prevalence of depressive symptoms was similar in patients with LB compared to patients with no evidence of infection. This suggests that depressive symptoms cannot be used to discriminate for LB in a tertiary Lyme center. © The Author 2017.

    Full Text Available Myeloproliferative neoplasms (MPN arise from genetic deficiencies at the level of pluripotent stem cells. Each of these neoplasms is a clonal stem cell disorder with specific phenotypic, genetic and clinical properties. Age is one of the most important factors in the development of symptoms and complications associated with MPNs.High white blood cell counts in chronic myelocytic leukemia also known as leukocytosis may lead to central nervous system findings. Tumors developing outside the bone marrow named as extramedullary myeloid tumors (EMMT could be detected at the initial diagnosis or during the prognosis of the disease, which may cause neurological symptoms due to pressure of leukemic cell mass on various tissues along with spinal cord. Central nervous system involvement and thrombocytopenic hemorrhage may lead to diverse neurological symptoms and findings.Transient ischemic attack and thrombotic stroke are the most common symptoms in polycythemia vera. Besides thrombosis and hemorrage, transformation to acute leukemia can cause neurological symptoms and findings. Transient ischemic attack, thrombotic stroke and specifically hemorrage can give rise to neurological symptoms similar to MPN in essential thrombocytosis.Extramedullary hematopoiesis refers to hematopoietic centers arise in organ/tissues other than bone marrow in myelofibrosis. Extramedullar hematopoietic centers may cause intracranial involvement, spinal cord compression, seizures and hydrocephalia. Though rare, extramedullary hematopoiesis can be detected in cranial/spinal meninges, paraspinal tissue and intracerebral regions. Extramedullary hematopoiesis has been reported in peripheral neurons, choroid plexus, pituitary, orbits, orbital and lacrimal fossa and in sphenoidal sinuses. [Cukurova Med J 2013; 38(2.000: 157-169

  17. Evidence for the use of Levomepromazine for symptom control in the palliative care setting: a systematic review

    2013-01-01

    Background Levomepromazine is an antipsychotic drug that is used clinically for a variety of distressing symptoms in palliative and end-of-life care. We undertook a systematic review based on the question “What is the published evidence for the use of levomepromazine in palliative symptom control?”. Methods To determine the level of evidence for the use of levomepromazine in palliative symptom control, and to discover gaps in evidence, relevant studies were identified using a detailed, multi-step search strategy. Emerging data was then scrutinized using appropriate assessment tools, and the strength of evidence systematically graded in accordance with the Oxford Centre for Evidence-Based Medicine’s ‘levels of evidence’ tool. The electronic databases Medline, Embase, Cochrane, PsychInfo and Ovid Nursing, together with hand-searching and cross-referencing provided the full research platform on which the review is based. Results 33 articles including 9 systematic reviews met the inclusion criteria: 15 on palliative sedation, 8 regarding nausea and three on delirium and restlessness, one on pain and six with other foci. The studies varied greatly in both design and sample size. Levels of evidence ranged from level 2b to level 5, with the majority being level 3 (non-randomized, non-consecutive or cohort studies n = 22), with the quality of reporting for the included studies being only low to medium. Conclusion Levomepromazine is widely used in palliative care as antipsychotic, anxiolytic, antiemetic and sedative drug. However, the supporting evidence is limited to open series and case reports. Thus prospective randomized trials are needed to support evidence-based guidelines. PMID:23331515

    To evaluate the role of chronic cerebral lactic acidosis in mitochondrial encephalomyopathy, lactic acidosis, and stroke-like episodes (MELAS). The authors studied 91 individuals from 34 families with MELAS and the A3243G point mutation and 15 individuals from two families with myoclonus epilepsy and ragged red fibers (MERRF) and the A8344G mutation. Subjects were divided into four groups. Paternal relatives were studied as controls (Group 1). The maternally related subjects were divided clinically into three groups: asymptomatic (no clinical evidence of neurologic disease) (Group 2), oligosymptomatic (neurologic symptoms but without the full clinical picture of MELAS or MERRF) (Group 3), and symptomatic (fulfilling MELAS or MERRF criteria) (Group 4). The authors performed a standardized neurologic examination, neuropsychological testing, MRS, and leukocyte DNA analysis in all subjects. The symptomatic and oligosymptomatic MELAS subjects had significantly higher ventricular lactate than the other groups. There was a significant correlation between degree of neuropsychological and neurologic impairment and cerebral lactic acidosis as estimated by ventricular MRS lactate levels. High levels of ventricular lactate, the brain spectroscopic signature of MELAS, are associated with more severe neurologic impairment.

    BackgroundEvidence suggests that the gut microbiota play an important role in gastrointestinal problems. AimTo give clinicians a practical reference guide on the role of specified probiotics in managing particular lower gastrointestinal symptoms/problems by means of a systematic review-based consensus. MethodsSystematic literature searching identified randomised, placebo-controlled trials in adults; evidence for each symptom/problem was graded and statements developed (consensus process; 10-member panel). As results cannot be generalised between different probiotics, individual probiotics were identified for each statement. ResultsThirty seven studies were included; mostly on irritable bowel syndrome [IBS; 19 studies; treatment responder rates: 18–80% (specific probiotics), 5–50% (placebo)] or antibiotic-associated diarrhoea (AAD; 10 studies). Statements with 100% agreement and ‘high’ evidence levels indicated that: (i) specific probiotics help reduce overall symptom burden and abdominal pain in some IBS patients; (ii) in patients receiving antibiotics/Helicobacter pylori eradication therapy, specified probiotics are helpful as adjuvants to prevent/reduce the duration/intensity of AAD; (iii) probiotics have favourable safety in patients in primary care. Items with 70–100% agreement and ‘moderate’ evidence were: (i) specific probiotics help relieve overall symptom burden in some patients with diarrhoea-predominant IBS, and reduce bloating/distension and improve bowel movement frequency/consistency in some IBS patients and (ii) with some probiotics, improved symptoms have led to improvement in quality of life. ConclusionsSpecified probiotics can provide benefit in IBS and antibiotic-associated diarrhoea; relatively few studies in other indications suggested benefits warranting further research. This study provides practical guidance on which probiotic to select for a specific problem. PMID:23981066

    The authors present divergent opinions on the pathogenesis of vibratory syndrome, and primarily on its angio-neurological form, i.e. vascular, neurogenic and immunological theory. In the light of these concepts the clinical manifestations of vibratory syndrome are discussed in view of both systemic and local developments. The issues concerning neurological diagnostics with reference to the usefulness of electrophysiological methods are thoroughly analysed. Difficulties in early diagnosis and identification of symptoms that distinguish vibratory syndrome from other syndromes with similar manifestations are highlighted.

    This study aims to examine how working hours influence depressive symptoms and the association between working hours and depressive symptoms differently across genders. The sample consists of salaried workers aged 25-64 years who participated in two consecutive waves of the seven-wave Korean Welfare Panel Study (2007-2013) (n = 6813 individuals, 27,986 observations) which is a survey of a nationally representative sample of the South Korean population. I apply logit regression and fixed-effects logit regression to examine the causal relation between (intra-)individual changes of working hours and depressive symptoms over a 7-year period. Results from logit model and fixed-effects logit model show that less than 30 h of work per week and more than 60 h of work per week are associated with significantly higher levels of depressive symptoms. Sex-stratified analyses reveal that women who worked over 60 h per week were at increased risk of showing depressive symptoms compared with women who worked 30-40 h per week. No significant increase in depressive symptoms was seen in men who worked more than 60 h per week. However, men working less than 30 h per week are more likely to report higher levels of depressive symptoms. These results suggest that work arrangement affects the mental health of men and women differently.

    Two models of posttraumatic stress disorder (PTSD) have received the most empirical support in confirmatory factor analytic studies: King, Leskin, King, and Weathers' (1998) Emotional Numbing model of reexperiencing, avoidance, emotional numbing and hyperarousal; and Simms, Watson, and Doebbeling's (2002) Dysphoria model of reexperiencing, avoidance, dysphoria and hyperarousal. These models only differ in placement of three PTSD symptoms: sleep problems (D1), irritability (D2), and concentration problems (D3). In the present study, we recruited 252 women victims of domestic violence and tested whether there is empirical support to separate these three PTSD symptoms into a fifth factor, while retaining the Emotional Numbing and Dysphoria models' remaining four factors. Confirmatory factor analytic findings demonstrated that separating the three symptoms into a separate factor significantly enhanced model fit for the Emotional Numbing and Dysphoria models. These three symptoms may represent a unique latent construct. Implications are discussed. Copyright © 2010 Elsevier Ltd. All rights reserved.

  4. Microbiota and neurologic diseases: potential effects of probiotics.

    2016-10-19

    The microbiota colonizing the gastrointestinal tract have been associated with both gastrointestinal and extra-gastrointestinal diseases. In recent years, considerable interest has been devoted to their role in the development of neurologic diseases, as many studies have described bidirectional communication between the central nervous system and the gut, the so-called "microbiota-gut-brain axis". Considering the ability of probiotics (i.e., live non-pathogenic microorganisms) to restore the normal microbial population and produce benefits for the host, their potential effects have been investigated in the context of neurologic diseases. The main aims of this review are to analyse the relationship between the gut microbiota and brain disorders and to evaluate the current evidence for the use of probiotics in the treatment and prevention of neurologic conditions. Overall, trials involving animal models and adults have reported encouraging results, suggesting that the administration of probiotic strains may exert some prophylactic and therapeutic effects in a wide range of neurologic conditions. Studies involving children have mainly focused on autism spectrum disorder and have shown that probiotics seem to improve neuro behavioural symptoms. However, the available data are incomplete and far from conclusive. The potential usefulness of probiotics in preventing or treating neurologic diseases is becoming a topic of great interest. However, deeper studies are needed to understand which formulation, dosage and timing might represent the optimal regimen for each specific neurologic disease and what populations can benefit. Moreover, future trials should also consider the tolerability and safety of probiotics in patients with neurologic diseases.

    The objective was to investigate the association between receiving care under the medical home model and parental assessment of the severity of asthma symptoms. It was hypothesized that parents of children who received care under the medical home model reported less severe asthma symptoms compared with their counterparts, whose care did not meet the medical home criteria. Secondary analyses were conducted using cross-sectional data from the 2011-2012 National Survey of Children's Health. Children with asthma aged 0-17 years were included and classified as receiving care from the medical home if their care contained 5 components: a personal doctor, a usual source of sick care, family-centered care, no problems getting referrals, and effective care coordination. Ordinal logistic regression was used to examine the relationship between parent-rated severity of asthma symptoms (mild, moderate, and severe symptoms) and the medical home. Approximately 52% of 8229 children who reported having asthma received care from the medical home. Only 30.8% of children with severe asthma symptoms received care that met the medical home criteria, compared to 55.7% of children with mild symptoms. After accounting for confounding factors, obtaining care under the medical home model decreased the odds of parent-reported severe asthma symptoms by 31% (adjusted odds ratio 0.69; 95% CI, 0.56-0.85). Study results suggest that the medical home model can reduce parent-rated severity of asthma symptoms. The findings highlight the importance of providing medical home care to children with asthma to improve the outcomes that matter most to children and their families.

  6. Associations between infant negative affect and parent anxiety symptoms are bidirectional: Evidence from mothers and fathers

    Full Text Available Little is known about child-based effects on parents’ anxiety symptoms early in life despite the possibility that child characteristics may contribute to the quality of the early environment and children’s own long-term risk for psychological disorder. We examined bidirectional effects between parent anxiety symptoms and infant fear-based negative affect using a prospective adoption design. Infant fear-based negative affect and adoptive parent anxiety symptoms were assessed at child ages 9, 18, and 27 months. Birth parent negative affect was assessed at child age 18 months. More anxiety symptoms in adoptive parents at child age 9 months predicted more negative affect in infants 9 months later. More infant negative affect at child age 9 months predicted more anxiety symptoms in adoptive parents 18 months later. Patterns of results did not differ for adoptive mothers and adoptive fathers. Birth parent negative affect was unrelated to infant or adoptive parent measures. Consistent with expectations, associations between infant negative affect and rearing parents’ anxiety symptoms appear to be bidirectional. In addition to traditional parent-to-child effects, our results suggest that infants’ characteristics may contribute to parent qualities that are known to impact childhood outcomes.

    'Neuromarketing' is a term that has often been used in the media in recent years. These public discussions have generally centered around potential ethical aspects and the public fear of negative consequences for society in general, and consumers in particular. However, positive contributions to the scientific discourse from developing a biological model that tries to explain context-situated human behavior such as consumption have often been neglected. We argue for a differentiated terminology, naming commercial applications of neuroscientific methods 'neuromarketing' and scientific ones 'consumer neuroscience'. While marketing scholars have eagerly integrated neuroscientific evidence into their theoretical framework, neurology has only recently started to draw its attention to the results of consumer neuroscience. In this paper we address key research topics of consumer neuroscience that we think are of interest for neurologists; namely the reward system, trust and ethical issues. We argue that there are overlapping research topics in neurology and consumer neuroscience where both sides can profit from collaboration. Further, neurologists joining the public discussion of ethical issues surrounding neuromarketing and consumer neuroscience could contribute standards and experience gained in clinical research. We identify the following areas where consumer neuroscience could contribute to the field of neurology:First, studies using game paradigms could help to gain further insights into the underlying pathophysiology of pathological gambling in Parkinson's disease, frontotemporal dementia, epilepsy, and Huntington's disease.Second, we identify compulsive buying as a common interest in neurology and consumer neuroscience. Paradigms commonly used in consumer neuroscience could be applied to patients suffering from Parkinson's disease and frontotemporal dementia to advance knowledge of this important behavioral symptom.Third, trust research in the medical context lacks

    2016-06-01

    The treatment of benign prostatic hyperplasia (BPH) is changing due to a greater understanding of the disease and the development of the functional concept of lower urinary tract symptoms (LUTS). To describe the current state of BPH and the diagnosis and treatment of LUTS. We summarise the issues presented and debated by a group of expert urologists during the First UROVI Congress, sponsored by the Spanish Urological Association. LUTS encompasses filling, voiding and postvoiding symptoms that affect patients' quality of life. The aetiological diagnosis is an important element in starting the most ideal treatment. For this reason, new alternative therapies (both pharmacological and surgical) are needed to help individually address the symptoms in the various patient profiles. There is now a new combination of drugs (6mg of solifenacin and 0.4mg of the tamsulosin oral controlled absorption system) for treating moderate to severe filling symptoms and emptying symptoms associated with BPH in patients who do not respond to monotherapy. Furthermore, new surgical techniques that are increasingly less invasive help provide surgical options for older patients and those with high comorbidity. The availability of drugs that can act on the various LUTS helps integrate the pathophysiological paradigm into the functional one, providing more appropriate treatment for our patients.

  10. A case for motor network contributions to schizophrenia symptoms: Evidence from resting-state connectivity.

    2017-09-01

    Though schizophrenia (SCZ) is classically defined based on positive symptoms and the negative symptoms of the disease prove to be debilitating for many patients, motor deficits are often present as well. A growing literature highlights the importance of motor systems and networks in the disease, and it may be the case that dysfunction in motor networks relates to the pathophysiology and etiology of SCZ. To test this and build upon recent work in SCZ and in at-risk populations, we investigated cortical and cerebellar motor functional networks at rest in SCZ and controls using publically available data. We analyzed data from 82 patients and 88 controls. We found key group differences in resting-state connectivity patterns that highlight dysfunction in motor circuits and also implicate the thalamus. Furthermore, we demonstrated that in SCZ, these resting-state networks are related to both positive and negative symptom severity. Though the ventral prefrontal cortex and corticostriatal pathways more broadly have been implicated in negative symptom severity, here we extend these findings to include motor-striatal connections, as increased connectivity between the primary motor cortex and basal ganglia was associated with more severe negative symptoms. Together, these findings implicate motor networks in the symptomatology of psychosis, and we speculate that these networks may be contributing to the etiology of the disease. Overt motor deficits in SCZ may signal underlying network dysfunction that contributes to the overall disease state.

    Equine protozoal myeloencephalitis (EPM) is a serious neurologic disease of horses in the Americas and Sarcocystis neurona is the most common etiologic agent. The distribution of S. neurona infections follows the geographical distributions of its definitive hosts, opossums (Didelphis virginiana, Didelphis albiventris). Recently, cats and skunks were reported as experimental and armadillos as natural intermediate hosts of S. neurona. In the present report, raccoons (Procyon lotor) were identified as a natural intermediate host of S. neurona. Two laboratory-raised opossums were found to shed S. neurona-like sporocysts after ingesting tongues of naturally-infected raccoons. Interferon-gamma gene knockout (KO) mice fed raccoon-opossum-derived sporocysts developed neurologic signs. S. neurona was identified immunohistochemically in tissues of KO mice fed sporocysts and the parasite was isolated in cell cultures inoculated with infected KO mouse tissues. The DNA obtained from the tongue of a naturally-infected raccoon, brains of KO mice that had neurological signs, and from the organisms recovered in cell cultures inoculated with brains of neurologic KO mice, corresponded to that of S. neurona. Two raccoons fed mature S. neurona sarcocysts did not shed sporocysts in their feces, indicating raccoons are not likely to be its definitive host. Two raccoons fed sporocysts from opossum feces developed clinical illness and S. neurona-associated encephalomyelitis was found in raccoons killed 14 and 22 days after feeding sporocysts; schizonts and merozoites were seen in encephalitic lesions.

    Full Text Available Abstract Background Attention Deficit/Hyperactivity Disorder (ADHD affects many children, adolescents, and adults and is associated with a number of impairments. Poor academic performance is related to ADHD in clinical samples. However, it is unclear to what extent core ADHD symptoms and scholastic impairment are related in non-referred school-aged children. Methods Data come from three population-based cohorts from Sweden, Denmark, and Finland, which are part of the Nordic Network on ADHD. The combined sample size was 13,087 children who were studied at ages 7–8 or 10–12 years. Teachers rated children on inattention and hyperactivity symptoms and reported children's scholastic performance on basic skills. Results There was a significant association in all cohorts between core ADHD symptoms and scholastic impairment in reading, writing, and mathematics. Particularly, inattention was related to a two to tenfold increase in scholastic impairment. Prevalence of hyperactivity symptoms was similar across the three cohorts, but inattention was lowest among children from the Finnish cohort, after stratification on living conditions. Conclusion These results extend previous reports of scholastic impairment among children with clinically diagnosed ADHD to non-referred population samples from three European countries. Surveillance policies should be implemented in school systems to catch children in need of behavioral or scholastic support early.

  15. Insomnia in central neurologic diseases--occurrence and management.

    2011-12-01

    The objective of this review is to highlight the impact of insomnia in central neurological disorders by providing information on its prevalence and give recommendations for diagnosis and treatment. Insomnia in neurological disorders is a frequent, but underestimated symptom. Its occurrence may be a direct consequence of the disease itself or may be secondary to pain, depression, other sleep disorders or the effects of medications. Insomnia can have a significant impact on the patient's cognitive and physical function and may be associated with psychological distress and depression. Diagnosis of insomnia is primarily based on medical history and validated questionnaires. Actigraphy is a helpful diagnostic tool for assessing the circadian sleep-wake rhythm. For differential diagnosis and to measure the duration of sleep full polysomnography may be recommended. Prior to initiating treatment the cause of insomnia must be clearly identified. First line treatment aims at the underlying neurologic disease. The few high quality treatment studies show that short term treatment with hypnotics may be recommended in most disorders after having ruled out high risk for adverse effects. Sedating antidepressants may be an effective treatment for insomnia in stroke and Parkinson's disease (PD) patients. Melatonin and light treatment can stabilize the sleep-wake circadian rhythm and shorten sleep latency in dementias and PD. Cognitive behavioral therapy (CBT) can be effective in treating insomnia symptoms associated with most of the central neurological diseases. The prevalence and treatment of insomnia in neurological diseases still need to be studied in larger patient groups with randomized clinical trials to a) better understand their impact and causal relationship and b) to develop and improve specific evidence-based treatment strategies.

    Negative mood states are composed of symptoms of depression and anxiety, and by a third factor related to stress, tension and irritability. We sought to clarify the nature of the relationships between the factors by studying twin pairs. A total of 503 monozygotic twin pairs completed the Depression Anxiety Stress Scales (DASS), an instrument that assesses symptoms of depression, anxiety and stress-tension. We applied a recently developed twin regression methodology - Inference about Causation from Examination of FAmiliaL CONfounding (ICE FALCON) - to test for evidence consistent with the existence of 'causal' influences between the DASS factors. There was evidence consistent with the stress-tension factor having a causal influence on both the depression (p anxiety factors (p = 0.001), and for the depression factor having a causal influence on the anxiety factor (p stress-tension in the structure of negative mood states, and that interventions that target it may be particularly effective in reducing depression and anxiety symptoms.

    Good literary fiction has the potential to move us, extend our sense of life, transform our prospective views and help us in the face of adversity. A neurological disorder is likely to be the most challenging experience a human being may have to confront in a lifetime. As such, literary recreations of illnesses have a doubly powerful effect. Study the synergies between neurology and fictional literature with particular reference to narrative based medicine (NBM). Doctors establish boundaries between the normal and the abnormal. Taking a clinical history is an act of interpretation in which the doctor integrates the science of objective signs and measurable quantities with the art of subjective clinical judgment. The more discrepancy there is between the patient's experience with the illness and the doctor's interpretation of that disease, the less likely the doctor-patient interaction is to succeed. NBM contributes to a better discernment of the meanings, thus considering disease as a biographical event rather than just a natural fact. Drawing from their own experience with disease, writers of fiction provide universal insights through their narratives, whilst neuroscientists, like Cajal, have occasionally devoted their scientific knowledge to literary narratives. Furthermore, neurologists from Alzheimer to Oliver Sacks remind us of the essential value of NBM in the clinic. Integrating NBM (the narrative of patients) and the classic holistic approach to patients with our current paradigm of evidence based medicine represents a challenge as relevant to neurologists as keeping up with technological and scientific advances.

  18. Neurological Consequences of Obesity

    Science.gov (United States)

    O’Brien, Phillipe D.; Hinder, Lucy M.; Callaghan, Brian C.; Feldman, Eva L.

    2017-01-01

    Obesity, primarily a consequence of poor dietary choices and an increased sedentary lifestyle, has become a global pandemic that brings with it enormous medical, social, and economic challenges. Not only does obesity increase the risk of cardiovascular disease and certain cancers, but it is also recognized as a key driver of other metabolic syndrome (MetS) components. These components include insulin resistance, hyperglycemia with prediabetes or type 2 diabetes, dyslipidemia, and hypertension, and are underlying contributors to systemic metabolic dysfunction. More recently, obesity and diet-induced metabolic dysfunction have been identified as risk factors for the development of a wide variety of neurological disorders in both the central and peripheral nervous systems. An abundance of literature has shown that obesity is associated with mild cognitive impairment and altered hippocampal structure and function, and there is a robust correlation between obesity and Alzheimer’s type dementia. Similarly, many reports show that both the autonomic and somatic components of the peripheral nervous system are impacted by obesity. The autonomic nervous system, under control of the hypothalamus, displays altered catabolic and anabolic processes in obese individuals attributed to sympathetic-parasympathetic imbalances. A close association also exists between obesity and polyneuropathy, a complication most commonly found in prediabetic and diabetic patients, and is likely secondary to a combination of obesity-induced dyslipidemia with hyperglycemia. This review will outline the pathophysiological development of obesity and dyslipidemia, discuss the adverse impact of these conditions on the nervous system, and provide evidence for lipotoxicity and metabolic inflammation as the drivers underlying the neurological consequences of obesity. In addition, this review will examine the benefits of lifestyle and surgical interventions in obesity-induced neurological disorders. PMID

    Shi, Fu-Dong; Jia, Jian-Ping

    2011-11-29

    In the wake of dramatic economic success during the past 2 decades, the specialized field of neurology has undergone a significant transformation in China. With an increase in life expectancy, the problems of aging and cognition have grown. Lifestyle alterations have been associated with an epidemiologic transition both in the incidence and etiology of stroke. These changes, together with an array of social issues and institution of health care reform, are creating challenges for practicing neurologists throughout China. Notable problems include overcrowded, decrepit facilities, overloaded physician schedules, deteriorating physician-patient relationships, and an insufficient infrastructure to accommodate patients who need specialized neurologic care. Conversely, with the creation of large and sophisticated neurology centers in many cities across the country, tremendous opportunities exist. Developments in neurologic subspecialties enable delivery of high-quality care. Clinical and translational research based on large patient populations as well as highly sophisticated technologies are emerging in many neurologic centers and pharmaceutical companies. Child neurology and neurorehabilitation will be fast-developing subdisciplines. Given China's extensive population, the growth and progress of its neurology complex, and its ever-improving quality control, it is reasonable to anticipate that Chinese neurologists will contribute notably to unraveling the pathogenic factors causing neurologic diseases and to providing new therapeutic solutions.

    Aim The aim of the present study was to assess the association of gestational diabetes mellitus (GDM) with prenatal and postnatal depressive symptoms in a sample of pregnant women in Greece. Earlier research supports a relationship between depression and diabetes, but only a few studies have examined the relationship between GDM and perinatal depressive symptomatology. A total of 117 women in their third trimester of pregnancy participated in the study. Demographic and obstetric history data were recorded during women's third trimester of pregnancy. Depressive symptoms were assessed with the validated Greek version of the Edinburg Postnatal Depression Scale (EPDS) at two time points: on the third trimester of pregnancy and on the first week postpartum. Findings Prevalence of GDM was 14.5%. Probable diagnosis of depression occurred for 12% of the sample during the antenatal assessment and 15.1% in the postpartum assessment. In the first week postpartum, women with GDM had significantly higher postpartum (but no antenatal) EPDS scores compared with the non-GDM cohort. In conclusion, GDM appears to be associated with depressive symptoms in the first week postpartum. Clinical implications and recommendations for future research are discussed, emphasizing the importance of closely monitoring women with GDM who seem more vulnerable to developing depressive symptomatology during the postnatal period.

    SSc is a rare autoimmune CTD characterized by thickening and fibrosis of skin and internal organs. There is significant mortality and no cure. Sleep disturbance has been identified as an important contributor to poor quality of life. The objective was to investigate socio-demographic and medical factors potentially associated with sleep disturbance in SSc. The sample consisted of patients from the Canadian Scleroderma Research Group's (CSRG) 15-centre, pan-Canadian Registry assessed with the 8-item Patient-Reported Outcome Measurement Information System (PROMIS) sleep disturbance scale short form, version 1.0. Pearson's correlations were used to assess bivariate association of socio-demographic and medical variables with PROMIS sleep scores. The independent association of PROMIS sleep disturbance scores and factors previously identified as associated with sleep disturbance in the general population, in SSc and other rheumatic diseases, was assessed using multiple linear regression. Among 397 patients in the study (88% female, mean age 57.5 years), 25% (n = 98) had diffuse cutaneous SSc. Mean duration since onset of non-RP symptoms was 10.6 years. Number of gastrointestinal symptoms (standardized regression coefficient β = 0.19, P = 0.001), pain severity (β = 0.21, P sleep disturbance. Gastrointestinal symptoms, pain and pruritus were associated with sleep disturbance in SSc. Additional research is needed on sleep in SSc so that well-informed sleep interventions can be developed and tested.

    There are no studies researching the relationship between house-poor persons and mental health. Therefore, this study aimed to investigate the relationship between house-poor status and depressive symptoms. To examine the relationship between the house-poor and depressive symptoms according to household income. Data from the Korean Welfare Panel Study were used. House-poor were defined as people having possession with over 10% house-related interest in disposable income. About 7,565 participants over the age of 19 years were followed up from 2011 to 2013. The generalized estimating equations were used for analysis. Individuals with more house-related debt showed increasingly higher depression scores (possession with under 5% related debt to disposable income β = 0.2024, p = .1544; under 10% β = 0.7030, p = .0008; over 10% β = 1.3207, p debts to disposable income had higher depression scores than individuals without house ownership (no possession β = 0.8927, p < .0001). Individuals without houses and individuals owning houses with higher percentages of house-related interests showed higher levels of depressive symptoms. Therefore, this study affirmed that the importance of considering the most vulnerable groups in addressing the mental health of individual. © The Author(s) 2016.

  3. The neurological basis of occupation.

    2007-01-01

    The purpose of the present paper was to survey the literature about the neurological basis of human activity and its relationship to occupation and health. Activities related to neurological function were organized into three categories: those that activate the brain's reward system; those that promote the relaxation response; and those that preserve cognitive function into old age. The results from the literature review correlating neurological evidence and activities showed that purposeful and meaningful activities could counter the effects of stress-related diseases and reduce the risk for dementia. Specifically, it was found that music, drawing, meditation, reading, arts and crafts, and home repairs, for example, can stimulate the neurogical system and enhance health and well-being, Prospective research studies are needed to examine the effects of purposeful activities on reducing stress and slowing the rate of cognitive decline.

    To determine if cognitive processing, and subjective and physiological responses to stress and relaxation differed between an irritable bowel syndrome (IBS) group and control group. How these variables relate to the severity of IBS symptoms was also determined. Twenty-one IBS participants and 20 controls provided cognitive (attention and processing), subjective (perceived stress and vigour), and physiological (heart rate, blood pressure, and skin conductance) data during a relaxation and stress phase. Logistic regression analyses determined which variables are related to the IBS group and hierarchical linear regression assessed how the variables are related to the severity of IBS symptoms. Subjective and cognitive factors (drowsiness at baseline, total vigour, and reduced Stroop colour-naming accuracy for negative words) are significantly related to IBS, χ2 (3, N=41)=23.67, pself-schema, as well as perceived low vigour were important in categorising IBS. Low subjective vigour and reduced physiological reactivity to both relaxation and stress conditions were associated with IBS severity, suggestive of illness-related allostatic load.

    Animal-assisted therapy (AAT) includes a set of nonpharmacological interventions aimed at improving human health through the use of trained or untrained animals. In recent decades, AAT has been trialed for different neurological and psychiatric disorders. In patients with dementia, interaction with animals seems to have a positive influence on aggressiveness and anxiety and to ameliorate quality of life and relationship skills. In psychiatric patients, AAT seems to increase motivation and self-esteem, improve prosocial conduct, and decrease behavioral problems. The aim of this study is to review the literature on AAT for elderly people with dementia and psychiatric disorders. Other fields of possible application for AAT are suggested.

  6. [Neurology of hysteria (conversion disorder)].

    2014-07-01

    Hysteria has served as an important driving force in the development of both neurology and psychiatry. Jean Martin Charcot's devotion to mesmerism for treating hysterical patients evoked the invention of psychoanalysis by Sigmund Freud. Meanwhile, Joseph Babinski took over the challenge to discriminate between organic and hysterical patients from Charcot and found Babinski's sign, the greatest milestone in modern neurological symptomatology. Nowadays, the usage of the term hysteria is avoided. However, new terms and new classifications are complicated and inconsistent between the two representative taxonomies, the DSM-IV and ICD-10. In the ICD-10, even the alternative term conversion disorder, which was becoming familiar to neurologists, has also disappeared as a group name. The diagnosis of hysteria remains important in clinical neurology. Extensive exclusive diagnoses and over investigation, including various imaging studies, should be avoided because they may prolong the disease course and fix their symptoms. Psychological reasons that seem to explain the conversion are not considered reliable. Positive neurological signs suggesting nonorganic etiologies are the most reliable measures for diagnosing hysteria, as Babinski first argued. Hysterical paresis has several characteristics, such as giving-way weakness or peculiar distributions of weakness. Signs to uncover nonorganic paresis utilizing synergy include Hoover's test and the Sonoo abductor test.

    The objective was to update previous evidence-based medicine reviews of treatments for motor symptoms of Parkinson's disease published between 2002 and 2005. Level I (randomized, controlled trial) reports of pharmacological, surgical, and nonpharmacological interventions for the motor symptoms of Parkinson's disease between January 2004 (2001 for nonpharmacological) and December 2010 were reviewed. Criteria for inclusion, clinical indications, ranking, efficacy conclusions, safety, and implications for clinical practice followed the original program outline and adhered to evidence-based medicine methodology. Sixty-eight new studies qualified for review. Piribedil, pramipexole, pramipexole extended release, ropinirole, rotigotine, cabergoline, and pergolide were all efficacious as symptomatic monotherapy; ropinirole prolonged release was likely efficacious. All were efficacious as a symptomatic adjunct except pramipexole extended release, for which there is insufficient evidence. For prevention/delay of motor fluctuations, pramipexole and cabergoline were efficacious, and for prevention/delay of dyskinesia, pramipexole, ropinirole, ropinirole prolonged release, and cabergoline were all efficacious, whereas pergolide was likely efficacious. Duodenal infusion of levodopa was likely efficacious in the treatment of motor complications, but the practice implication is investigational. Entacapone was nonefficacious as a symptomatic adjunct to levodopa in nonfluctuating patients and nonefficacious in the prevention/delay of motor complications. Rasagiline conclusions were revised to efficacious as a symptomatic adjunct, and as treatment for motor fluctuations. Clozapine was efficacious in dyskinesia, but because of safety issues, the practice implication is possibly useful. Bilateral subthalamic nucleus deep brain stimulation, bilateral globus pallidus stimulation, and unilateral pallidotomy were updated to efficacious for motor complications. Physical therapy was revised

    To delineate optimal diagnostic and therapeutic approaches to congenital muscular dystrophy (CMD) through a systematic review and analysis of the currently available literature. Relevant, peer-reviewed research articles were identified using a literature search of the MEDLINE, EMBASE, and Scopus databases. Diagnostic and therapeutic data from these articles were extracted and analyzed in accordance with the American Academy of Neurology classification of evidence schemes for diagnostic, prognostic, and therapeutic studies. Recommendations were linked to the strength of the evidence, other related literature, and general principles of care. The geographic and ethnic backgrounds, clinical features, brain imaging studies, muscle imaging studies, and muscle biopsies of children with suspected CMD help predict subtype-specific diagnoses. Genetic testing can confirm some subtype-specific diagnoses, but not all causative genes for CMD have been described. Seizures and respiratory complications occur in specific subtypes. There is insufficient evidence to determine the efficacy of various treatment interventions to optimize respiratory, orthopedic, and nutritional outcomes, and more data are needed regarding complications. Multidisciplinary care by experienced teams is important for diagnosing and promoting the health of children with CMD. Accurate assessment of clinical presentations and genetic data will help in identifying the correct subtype-specific diagnosis in many cases. Multiorgan system complications occur frequently; surveillance and prompt interventions are likely to be beneficial for affected children. More research is needed to fill gaps in knowledge regarding this category of muscular dystrophies. © 2015 American Academy of Neurology.

    2011-01-01

    Emerging research has examined individual differences in affective forecasting; however, we are aware of no published study to date linking psychopathology symptoms to affective forecasting problems. Pitting cognitive theory against depressive realism theory, we examined whether dysphoria was associated with negatively biased affective forecasts or greater accuracy. Participants (n = 325) supplied predicted and actual emotional reactions for three days surrounding an emotionally-evocative relational event, Valentine’s Day. Predictions were made a month prior to the holiday. Consistent with cognitive theory, we found evidence for a dysphoric forecasting bias – the tendency of individuals in dysphoric states to overpredict negative emotional reactions to future events. The dysphoric forecasting bias was robust across ratings of positive and negative affect, forecasts for pleasant and unpleasant scenarios, continuous and categorical operationalizations of dysphoria, and three time points of observation. Similar biases were not observed in analyses examining the independent effects of anxiety and hypomania. Findings provide empirical evidence for the long assumed influence of depressive symptoms on future expectations. The present investigation has implications for affective forecasting studies examining information processing constructs, decision making, and broader domains of psychopathology. PMID:22397734

    2014-12-01

    Sports neurology is an emerging area of subspecialty. Neurologists and non-neurologists evaluating and managing individuals participating in sports will encounter emergencies that directly or indirectly involve the nervous system. Since the primary specialty of sports medicine physicians and other practitioners involved in the delivery of medical care to athletes in emergency situations varies significantly, experience in recognition and management of neurologic emergencies in sports will vary as well. This article provides a review of information and elements essential to neurologic emergencies in sports for the practicing neurologist, although content may be of benefit to readers of varying background and expertise. Both common neurologic emergencies and less common but noteworthy neurologic emergencies are reviewed in this article. Issues that are fairly unique to sports participation are highlighted in this review. General concepts and principles related to treatment of neurologic emergencies that are often encountered unrelated to sports (eg, recognition and treatment of status epilepticus, increased intracranial pressure) are discussed but are not the focus of this article. Neurologic emergencies can involve any region of the nervous system (eg, brain, spine/spinal cord, peripheral nerves, muscles). In addition to neurologic emergencies that represent direct sports-related neurologic complications, indirect (systemic and generalized) sports-related emergencies with significant neurologic consequences can occur and are also discussed in this article. Neurologists and others involved in the care of athletes should consider neurologic emergencies in sports when planning and providing medical care.

    Vaginal atrophy (VA) is a chronic medical condition. It is managed unsatisfactorily, despite its high prevalence and negative impact on female quality of life. In order to meet their needs, it would be useful to know what women perceive to be the most bothersome symptom (MBS) of VA. Cross-sectional, multicenter study of 913 postmenopausal women consulting 22 gynecological outpatient services. Prevalence of the MBS perceived by postmenopausal women of different age and vaginal condition. Vaginal dryness was the most prevalent MBS (54.4%), followed by dyspareunia (17.6%), itching (7.8%), dysuria (5.9%) and burning (2.0%). The prevalence of vaginal dryness as the MBS increased with years since menopause, while that of itching, dysuria and burning remained approximately constant over time. The prevalence of dyspareunia as the MBS was 26.2% in the first 6 years after menopause and declined thereafter, to 8.8%. Among all postmenopausal women vaginal dryness per se, independent of dyspareunia, is the most commonly reported MBS. In each woman, the identification of the MBS may help to define more appropriate VA management. Copyright © 2017. Published by Elsevier B.V.

  15. Vomiting as a Symptom and Transmission Risk in Norovirus Illness: Evidence from Human Challenge Studies.

    Directory of Open Access Journals (Sweden)

    Amy E Kirby

    Full Text Available In the US, noroviruses are estimated to cause 21 million cases annually with economic losses reaching $2 billion. Outbreak investigations frequently implicate vomiting as a major transmission risk. However, little is known about the characteristics of vomiting as a symptom or the amount of virus present in emesis.Emesis samples and symptomology data were obtained from previous norovirus human challenge studies with GI.1 Norwalk virus, GII.2 Snow Mountain virus, and a pilot study with GII.1 Hawaii virus. Viral titers in emesis were determined using strain-specific quantitative RT-PCR. In all four studies, vomiting was common with 40-100% of infected subjects vomiting at least once. However, only 45% of subjects with vomiting also had diarrhea. Most of the emesis samples had detectable virus and the mean viral titers were 8.0 x 105 and 3.9 x 104 genomic equivalent copies (GEC/ml for GI and GII viruses, respectively (p = 0.02. Sample pH was correlated with GII.2 Snow Mountain virus detection.Half of all subjects with symptomatic infection experienced vomiting and the average subject shed 1.7 x 108 GEC in emesis. Unlike shedding through stool, vomiting is more likely to result in significant environmental contamination, leading to transmission through fomites and airborne droplets. This quantitative data will be critical for risk assessment studies to further understand norovirus transmission and develop effective control measures. The correlation between sample pH and virus detection is consistent with a single site of virus replication in the small intestine and stomach contents becoming contaminated by intestinal reflux. Additionally, the frequency of vomiting without concurrent diarrhea suggests that epidemiology studies that enroll subjects based on the presence of diarrhea may be significantly underestimating the true burden of norovirus disease.

    Maternal depression has been suggested as a risk factor for both poor child growth and development in many low- and middle-income countries, but the validity of many studies is hindered by small sample sizes, varying cut-offs used in depression diagnostics, and incomplete control of confounding factors. This study examines the association between maternal depressive symptoms (MDSs) and child physical growth and cognitive development in Madhya Pradesh, India, where poverty, malnutrition, and poor mental health coexist. Data were from a baseline household survey (n = 2,934) of a randomized controlled trial assessing an early childhood development programme. Multivariate linear and logistic regression analyses were conducted, adjusting for socio-economic factors to avoid confounding the association of mental health and child outcomes. MDS (measured using the Center for Epidemiologic Studies Short Depression Scale) was categorized as low, medium, and high in 47%, 42%, and 10% of mothers, respectively. The prevalence of child developmental delay ranged from 16% to 27% for various development domains. Compared with children of mothers with low MDS, those of high MDS mothers had lower height-for-age, weight-for-age, and weight-for-height z-scores (0.22, 0.21, and 0.15, respectively), a higher rate of stunting and underweight (~1.5 times), and higher rate of developmental delay (partial adjusted odds ratio ranged from 1.3-1.8 for different development domains and fully adjusted odds ratio = 1.4 for fine motor). Our results-that MDS is significantly associated with both child undernutrition and development delay-add to the call for practical interventions to address maternal depression to simultaneously address multiple outcomes for both women and children. © 2018 The Authors.

    The education of neurologists is debilitated worldwide. University professors are engaged in teaching, research and patient-care. This triple challenge is very demanding, and results in permanent insecurity of University employees. To compensate for the insufficient clinical training, some institutes in the USA employ academic staff members exclusively for teaching. The formation of new subspecialties hinders the education and training of general neurologists. At present, four generations of medical doctors are working together in hospitals. The two older generations educate the younger neurologists who have been brought up in the world of limitless network of sterile information. Therefore their manual skills at the bedside and their knowledge of emergency treatment are deficient. Demographics of medical doctors changed drastically. Twice as many women are working in neurology and psychiatry than men. Integrity of neurology is threatened by: (1) Separation of the cerebrovascular diseases from general neurology. Development of "stroke units" was facilitated by the better reimbursement for treatment and by the interest of the pharmaceutical companies. Healthcare politics promoted the split of neurology into two parts. The independent status of "stroke departments" will reduce the rest of clinical neurology to outpatient service. (2) The main argumentation to segregate the rare neurological diseases was that their research will provide benefit for the diseases with high prevalence. This argumentation serves territorial ambitions. The separation of rare diseases interferes with the teaching of differential diagnostics in neurological training. The traditional pragmatic neurology can not be retrieved. The faculty of neurology could retain its integrity by the improvement of diagnostic methods and the ever more effective drugs. Nevertheless, even the progression of neurological sciences induces dissociation of clinical neurology. Neurology shall suffer fragmentation if

    2017-10-13

    Spaceflight impacts multiple aspects of human physiology, which will require non-invasive countermeasures as mission length and distance from Earth increases and the capability for external medical intervention decreases. Studies on Earth have shown that probiotics have the potential to improve some of the conditions that have manifested during spaceflight, such as gastrointestinal distress, dermatitis, and respiratory infections. The constraints and risks of spaceflight make it imperative that probiotics are carefully selected based on their strain-specific benefits, doses, delivery mechanisms, and relevance to likely crew conditions prior to evaluation in astronauts. This review focuses on probiotics that have been incorporated into healthy human gastrointestinal microbiomes and associated clinically with improvements in inflammatory state or alleviation of symptoms of crew-relevant illness. These studies provide an evidence base for probiotic selection with the greatest potential to support crew health and well-being in spaceflight.

    The chemotherapeutic agent mitoxantrone was approved for use in multiple sclerosis (MS) in 2000. After a review of all the available evidence, the original report of the Therapeutics and Technology Assessment Subcommittee in 2003 concluded that mitoxantrone probably reduced clinical attack rates, MRI activity, and disease progression. Subsequent reports of decreased systolic function, heart failure, and leukemia prompted the US Food and Drug Administration to institute a "black box" warning in 2005. This review was undertaken to examine the available literature on the efficacy and safety of mitoxantrone use in patients with MS since the initial report. Relevant articles were obtained through a review of the medical literature and the strength of the available evidence was graded according to the American Academy of Neurology evidence classification scheme. The accumulated Class III and IV evidence suggests an increased incidence of systolic dysfunction and therapy-related acute leukemia (TRAL) with mitoxantrone therapy. Systolic dysfunction occurs in approximately 12% of patients with MS treated with mitoxantrone, congestive heart failure occurs in approximately 0.4%, and leukemia occurs in approximately 0.8%. The number needed to harm is 8 for systolic dysfunction and 123 for TRAL. There is no new efficacy evidence that would change the recommendation from the previous report. The risk of systolic dysfunction and leukemia in patients treated with mitoxantrone is higher than suggested at the time of the previous report, although comprehensive postmarketing surveillance data are lacking.

    Neurological diseases are frequently associated with swallowing disorders and malnutrition. Moreover, patients with neurological diseases are at increased risk of micronutrient deficiency and dehydration. On the other hand, nutritional factors may be involved in the pathogenesis of neurological diseases. Multiple causes for the development of malnutrition in patients with neurological diseases are known including oropharyngeal dysphagia, impaired consciousness, perception deficits, cognitive dysfunction, and increased needs. The present evidence- and consensus-based guideline addresses clinical questions on best medical nutrition therapy in patients with neurological diseases. Among them, management of oropharyngeal dysphagia plays a pivotal role. The guideline has been written by a multidisciplinary team and offers 88 recommendations for use in clinical practice for amyotrophic lateral sclerosis, Parkinson's disease, stroke and multiple sclerosis.

    Menopausal status and estrogen-containing hormone therapy may influence several neurological disorders, including Alzheimer's disease, epilepsy, migraine headache, multiple sclerosis, Parkinson's disease, sleep disorders, and stroke. For most of these illnesses, evidence on hormone therapy is insufficient to guide practice decisions. For stroke, clinical trial evidence indicates that hormone therapy increases risk of cerebral infarction. For women with Alzheimer's disease, estrogen treatment trials have tended to be small and of short duration. Most suggest that estrogen started after the onset of dementia symptoms does not meaningfully improve cognition or slow disease progression. Hormone therapy initiated after age 64 increased all-cause dementia in the Women's Health Initiative Memory Study. Many observational studies, however, report protective associations between hormone use and Alzheimer risk. Apparent risk reduction may represent a bias toward hormone therapy, since hormones are more often prescribed to healthier women. However, when compared to the Women's Health Initiative Memory Study, estrogen exposures in many observational studies reflect hormone initiation at a younger age, closer to the time of menopause. One intriguing hypothesis is that hormone therapy initiated or used during an early critical window may reduce later Alzheimer incidence. Public health implications of this hypothesis are important, but current data are inadequate to decide the issue.

    Extremely-low-birth-weight infants (ELBW) should be given nutrients to enable them to grow at the same rate as foetuses of the same gestational age, and lean body components, particularly the brain, are dependent on protein intake. Fortified human milk remains the best food for these preterms. Two groups of preterm infants weighing 580-1250 g and with a gestational age of 23-32 weeks were fed with different protein intakes in fortified human/maternal milk (3.5 g kg(-1) per day and 4.8 g kg(-1) per day in the control and extra-protein groups, respectively). The tolerance, intrahospital growth, neurological outcome and anthropometric data until 9 months corrected age were evaluated. The extra-protein regime showed an intrahospital growth advantage (mostly in growth of head circumference, p 0.02, and length, p 0.04) only in the preterms weighing 580-980 g and aged 23-30 weeks. In the same preterms, the Griffith Development Mental Score at 3 months corrected age showed higher scores than in the control group (p 0.04). Growth during the post-discharge period for the experimental group at 9 months corrected age showed mean z-score values for length higher than those in the control group (p 0.04).

    Osteoarthritis is a chronic disease characterized by irreversible damage to joint structures, including loss of articular cartilage, osteophyte formation, alterations in the subchondral bone and synovial inflammation. It has been shown that chondroitin sulfate interferes with the progression of structural changes in joint tissues and is used in the management of patients with osteoarthritis. This review summarizes data from relevant reports describing the mechanisms of action of chondroitin sulfate that may explain the beneficial effects of the drug and examines the evidence for clinical efficacy of oral chondroitin sulfate in osteoarthritis. Data included in the review were derived from a literature search in PubMed. Literature searches were performed in PubMed using the search terms 'chondroitin sulfate', 'pharmaceutical-grade', 'osteoarthritis', 'randomized clinical trials', 'humans'. The MEDLINE database was searched from January 1996 through August 2012 for all randomized controlled trials, meta-analyses, systematic reviews, and review articles of chondroitin sulfate in osteoarthritis. Chondroitin sulfate exerts in vitro a beneficial effect on the metabolism of different cell lines: chondrocytes, synoviocytes and cells from subchondral bone, all involved in osteoarthritis. It increases type II collagen and proteoglycan synthesis in human articular chondrocytes and is able to reduce the production of some pro-inflammatory factors and proteases, to reduce the cellular death process, and improve the anabolic/catabolic balance of the extracellular cartilage matrix (ECM). Clinical trials have reported a beneficial effect of chondroitin sulfate on pain and function. The structure-modifying effects of chondroitin sulfate have been reported and analyzed in recent meta-analyses. The results in knee osteoarthritis demonstrate a small but significant reduction in the rate of decline in joint space width. Because chondroitin sulfate quality of several nutraceuticals has

    In the last years with the increase of bariatric surgery, first of all as a result of new indications, a rise in the incidence of nutrient-related complications has been observed. Currently little is known about the impact of post-bariatric malnutrition and neurological complications. Wernicke's encephalopathy is a severe neurological syndrome which occurs as a result of thiamine deficiency. Wernicke-Korsakoff syndrome must be considered a serious neurological complication of bariatric surgery with significant morbidity and mortality, with rapidly progressing neurological symptoms, and must be treated immediately. We report the case of a 35 years-old male patient, affected by morbid obesity, anxious-depressive syndrome and alcohol use disorder, who after adjustable gastric banding implanted in another hospital developed a severe malnutrition and neurological syndrome. The patient showed poor adherence to the follow-up and to the dietary indications and after all, we needed to place a PEG for enteral nutrition in order to resolve the malnutrition condition and the neurological syndrome. Our experience emphasizes that preoperative selection and assessment of a patient's nutritional status according to guidelines, is required to identify potential problems, and that bariatric surgeons or physicians caring for patient who have undergone bariatric surgery should be familiar with the constellation of nutritional and neurological disorder that may occur after surgery. We want to remark the importance of preoperative selection of the patients, the follow-up and the cooperation between patient and physician in order to obtain the best result and avoid severe complications.

    International audience; The relationship between " Theory of Mind " (ToM) or more generally, social cognition and psychotic symptoms is largely supported by the actual literature. What is less known is the relationship between mood symptoms and ToM. Some studies found that bipolar disorder patients as well as depressed remitted patients have worse performances on ToM tasks than healthy subjects. This would explain the poor social abilities of depressive patients and constitute a risk factor o...

    To provide evidence-based recommendations for treatment of adults with an unprovoked first seizure. We defined relevant questions and systematically reviewed published studies according to the American Academy of Neurology's classification of evidence criteria; we based recommendations on evidence level. Adults with an unprovoked first seizure should be informed that their seizure recurrence risk is greatest early within the first 2 years (21%-45%) (Level A), and clinical variables associated with increased risk may include a prior brain insult (Level A), an EEG with epileptiform abnormalities (Level A), a significant brain-imaging abnormality (Level B), and a nocturnal seizure (Level B). Immediate antiepileptic drug (AED) therapy, as compared with delay of treatment pending a second seizure, is likely to reduce recurrence risk within the first 2 years (Level B) but may not improve quality of life (Level C). Over a longer term (>3 years), immediate AED treatment is unlikely to improve prognosis as measured by sustained seizure remission (Level B). Patients should be advised that risk of AED adverse events (AEs) may range from 7% to 31% (Level B) and that these AEs are likely predominantly mild and reversible. Clinicians' recommendations whether to initiate immediate AED treatment after a first seizure should be based on individualized assessments that weigh the risk of recurrence against the AEs of AED therapy, consider educated patient preferences, and advise that immediate treatment will not improve the long-term prognosis for seizure remission but will reduce seizure risk over the subsequent 2 years. © 2015 American Academy of Neurology.

    Postoperative neurologic symptoms after interscalene block and shoulder surgery have been reported to be relatively frequent. Reports of such symptoms after ultrasound-guided block have been variable. We evaluated 300 patients for neurologic symptoms after low-volume, ultrasound-guided interscalene block and arthroscopic shoulder surgery. Patients underwent ultrasound-guided interscalene block with 16 to 20 mL of 0.5% bupivacaine or a mix of 0.2% bupivacaine/1.2% mepivacaine solution, followed by propofol/ketamine sedation for ambulatory arthroscopic shoulder surgery. Patients were called at 10 days for evaluation of neurologic symptoms, and those with persistent symptoms were called again at 30 days, at which point neurologic evaluation was initiated. Details of patient demographics and block characteristics were collected to assess any association with persistent neurologic symptoms. Six of 300 patients reported symptoms at 10 days (2%), with one of these patients having persistent symptoms at 30 days (0.3%). This was significantly lower than rates of neurologic symptoms reported in preultrasound investigations with focused neurologic follow-up and similar to other studies performed in the ultrasound era. There was a modest correlation between the number of needle redirections during the block procedure and the presence of postoperative neurologic symptoms. Ultrasound guidance of interscalene block with 16- to 20-mL volumes of local anesthetic solution results in a lower frequency of postoperative neurologic symptoms at 10 and 30 days as compared with investigations in the preultrasound period.

    2017-01-01

    Adult-onset adrenoleukodystrophy is a rare x-linked inborn error of metabolism occurring predominantly in males with onset in early 30s. Here, we report a 34-year-old male with first signs of disease in early 20s manifesting as a pure psychiatric disorder. Prior to onset of neurological symptoms, this patient demonstrated a schizophrenia and bipolar-like presentation. The disease progressed over the next 10-13 years and his memory and motor problems became evident around the age of 33 years. Subsequently, diagnostic testing showed the typical magnetic resonance imaging and lab findings for adult-onset adrenoleukodystrophy. This case highlights adult-onset adrenoleukodystrophy which may present as a pure psychiatric disturbance in early adulthood and briefly discusses the prolonged time between the onset of psychiatric symptoms and the onset of neurological disease.

    Summary Neurology is a field known for “eponymophilia.” While eponym use has been a controversial issue in medicine, animal-related metaphoric descriptions continue to flourish in neurologic practice, particularly with the advent of neuroimaging. To provide practicing and trainee neurologists with a useful reference for all these colorful eponyms, we performed a literature review and summarized the various animal eponyms in the practice of neurology (and their etiologic implications) to date. We believe that the ability to recognize animal-like attributes in clinical neurology and neuroradiology may be attributed to a visual phenomenon known as pareidolia. We propose that animal eponyms are a useful method of recognizing clinical and radiologic patterns that aid in the diagnostic process and therefore are effective aidesmémoire and communicative tools that enliven and improve the practice of neurology.

  13. Neurological aspects of lead intoxication

    Lehner, H

    1980-05-08

    This study gives a survey over the medical and scientific literature on lead intoxications, which were published until 1979. Neurologic aspects are of particular interest. At present dramatic cases of lead intoxications occur only rarely. However, there are numerous studies about cases of chronical, partly subclinical intoxications. This chronical type of lead intoxication can become manifest clinically as relatively vague symptoms, for example vertigos, insomnia, headaches and weakness. Contrary to this, serious encephalopathies, even with fatal outcome, and polyneuropathies with typical paresis of the radial nerve are preferably observed in acute lead intoxications. Besides the numerous sources of intoxication, also the different opinions found in literature are discussed, concerning the effects of lead on the human body. The fact that there are differing opinions about the limiting value of the blood-lead level at which intoxication symptoms have to be expected, becomes apparent when the determined blood-lead level values are compared and evaluated. Besides the description of general intoxication effects, the discussion of the neurologic aspects found in literature - not only those concerning the central, but also the peripheral system - are preferably concerned. Reports about neuropsychical alterations due to lead exposure, which are mainly found in children, supplement the numerous descriptions of the macroscopic and microscopic alterations of the nervous system provoked by lead. Finally the therapeutic and prophylactic measures given in the literature are discussed.

    Miravalle, Augusto A; Schreiner, Teri

    2014-01-01

    This chapter reviews the most common neurologic disorders associated with common vaccines, evaluates the data linking the disorder with the vaccine, and discusses the potential mechanism of disease. A literature search was conducted in PubMed using a combination of the following terms: vaccines, vaccination, immunization, and neurologic complications. Data were also gathered from publications of the American Academy of Pediatrics Committee on Infectious Diseases, the World Health Organization, the US Centers for Disease Control and Prevention, and the Vaccine Adverse Event Reporting System. Neurologic complications of vaccination are rare. Many associations have been asserted without objective data to support a causal relationship. Rarely, patients with a neurologic complication will have a poor outcome. However, most patients recover fully from the neurologic complication. Vaccinations have altered the landscape of infectious disease. However, perception of risk associated with vaccinations has limited the success of disease eradication measures. Neurologic complications can be severe, and can provoke fear in potential vaccines. Evaluating whether there is causal link between neurologic disorders and vaccinations, not just temporal association, is critical to addressing public misperception of risk of vaccination. Among the vaccines available today, the cost-benefit analysis of vaccinations and complications strongly argues in favor of vaccination. © 2014 Elsevier B.V. All rights reserved.

    2013-01-01

    According to the American Heart Association, cardiomyopathies are classified as primary (solely or predominantly confined to heart muscle), secondary (those showing pathological myocardial involvement as part of a neuromuscular disorder) and those in which cardiomyopathy is the first/predominant manifestation of a neuromuscular disorder. Cardiomyopathies may be further classified as hypertrophic cardiomyopathy, dilated cardiomyopathy, restrictive cardiomyopathy, arrhythmogenic right ventricular cardiomyopathy, or unclassified cardiomyopathy (noncompaction, Takotsubo-cardiomyopathy). This review focuses on secondary cardiomyopathies and those in which cardiomyopathy is the predominant manifestation of a myopathy. Any of them may cause neurological disease, and any of them may be a manifestation of a neurological disorder. Neurological disease most frequently caused by cardiomyopathies is ischemic stroke, followed by transitory ischemic attack, syncope, or vertigo. Neurological disease, which most frequently manifests with cardiomyopathies are the neuromuscular disorders. Most commonly associated with cardiomyopathies are muscular dystrophies, myofibrillar myopathies, congenital myopathies and metabolic myopathies. Management of neurological disease caused by cardiomyopathies is not at variance from the same neurological disorders due to other causes. Management of secondary cardiomyopathies is not different from that of cardiomyopathies due to other causes either. Patients with neuromuscular disorders require early cardiologic investigations and close follow-ups, patients with cardiomyopathies require neurological investigation and avoidance of muscle toxic medication if a neuromuscular disorder is diagnosed. Which patients with cardiomyopathy profit most from primary stroke prevention is unsolved and requires further investigations. Copyright © 2013 Elsevier Inc. All rights reserved.

    To make evidence-based treatment recommendations for the medical and surgical treatment of patients with Parkinson disease (PD) with levodopa-induced motor fluctuations and dyskinesia. To that end, five questions were addressed. 1. Which medications reduce off time? 2. What is the relative efficacy of medications in reducing off time? 3. Which medications reduce dyskinesia? 4. Does deep brain stimulation (DBS) of the subthalamic nucleus (STN), globus pallidus interna (GPi), or ventral intermediate (VIM) nucleus of the thalamus reduce off time, dyskinesia, and antiparkinsonian medication usage and improve motor function? 5. Which factors predict improvement after DBS? A 10-member committee including movement disorder specialists and general neurologists evaluated the available evidence based on a structured literature review including MEDLINE, EMBASE, and Ovid databases from 1965 through June 2004. 1. Entacapone and rasagiline should be offered to reduce off time (Level A). Pergolide, pramipexole, ropinirole, and tolcapone should be considered to reduce off time (Level B). Apomorphine, cabergoline, and selegiline may be considered to reduce off time (Level C). 2. The available evidence does not establish superiority of one medicine over another in reducing off time (Level B). Sustained release carbidopa/levodopa and bromocriptine may be disregarded to reduce off time (Level C). 3. Amantadine may be considered to reduce dyskinesia (Level C). 4. Deep brain stimulation of the STN may be considered to improve motor function and reduce off time, dyskinesia, and medication usage (Level C). There is insufficient evidence to support or refute the efficacy of DBS of the GPi or VIM nucleus of the thalamus in reducing off time, dyskinesia, or medication usage, or to improve motor function. 5. Preoperative response to levodopa predicts better outcome after DBS of the STN (Level B).

  18. Rett syndrome: a neurological disorder with metabolic components

    Kyle, Stephanie M.

    2018-01-01

    Rett syndrome (RTT) is a neurological disorder caused by mutations in the X-linked gene methyl-CpG-binding protein 2 (MECP2), a ubiquitously expressed transcriptional regulator. Despite remarkable scientific progress since its discovery, the mechanism by which MECP2 mutations cause RTT symptoms is largely unknown. Consequently, treatment options for patients are currently limited and centred on symptom relief. Thought to be an entirely neurological disorder, RTT research has focused on the role of MECP2 in the central nervous system. However, the variety of phenotypes identified in Mecp2 mutant mouse models and RTT patients implicate important roles for MeCP2 in peripheral systems. Here, we review the history of RTT, highlighting breakthroughs in the field that have led us to present day. We explore the current evidence supporting metabolic dysfunction as a component of RTT, presenting recent studies that have revealed perturbed lipid metabolism in the brain and peripheral tissues of mouse models and patients. Such findings may have an impact on the quality of life of RTT patients as both dietary and drug intervention can alter lipid metabolism. Ultimately, we conclude that a thorough knowledge of MeCP2's varied functional targets in the brain and body will be required to treat this complex syndrome. PMID:29445033

    Many of Shakespeare's plays contain characters who appear to be afflicted by neurological or psychiatric disorders. Shakespeare, in his descriptive analysis of his protagonists, was contributing to the understanding of these disorders. In fact, Charcot frequently used Shakespearean references in his neurological teaching sessions, stressing how acute objective insight is essential to achieving expert clinical diagnosis. Charcot found in Shakespeare the same rigorous observational techniques for which he himself became famous. This chapter describes many of Shakespearean characters suffering from varied neurological disorders, including Parkinsonism, epilepsy, sleeping disturbances, dementia, headache, prion disease, and paralyses. © 2013 Elsevier B.V.

    Bariatric surgery is considered to be the most effective treatment of morbid obesity and improvement of obesity-related comorbidities, such as type II diabetes. However, both peripheral and central neurological complications can occur after bariatric surgery. Such complications tend to occur more frequently after bypass surgery than after sleeve gastrectomy (SG). The objective of this study was to identify the patients that presented post-operative neurological complications after undergoing SG and describe the incidence, presentation, and management of these complications. This was a retrospective study of 592 cases of SG performed between 2009 and 2014 with a special focus on patients who presented neurological complications. Of the 592 SG cases, only seven (1.18 %) patients presented neurological complications. All patients had uneventful post-operative course, but all reported feeding difficulties, accompanied by severe dysphagia, and rapid weight loss, with a mean weight loss of 35 kg (30-40 kg) 3 months after SG. All patients were readmitted owing to neurological symptoms that included paresthesia, abolition of deep tendon reflexes of the lower limbs, muscle pain, and motor and sensitive deficits in some cases. There were two cases of Wernicke's encephalopathy. All patients were treated for neuropathy secondary to vitamin B1 deficiency and had a significant improvement and/or resolution of their symptoms. Neurological complications after SG are rare and are often preceded by gastrointestinal symptoms, rapid weight loss, and lack of post-operative vitamin supplementation. Re-hospitalization and multidisciplinary team management are crucial to establish the diagnosis and initiate treatment.

    Our aim was to evaluate Wikipedia page visits in relation to the most common neurological disorders by determining which factors are related to peaks in Wikipedia searches for these conditions. Millions of people worldwide use the internet daily as a source of health information. Wikipedia is a popular free online encyclopedia used by patients and physicians to search for health-related information. The following Wikipedia articles were considered: Alzheimer's disease; Amyotrophic lateral sclerosis; Dementia; Epilepsy; Epileptic seizure; Migraine; Multiple sclerosis; Parkinson's disease; Stroke; Traumatic brain injury. We analyzed information regarding the total article views for 90 days and the rank of these articles among all those available in Wikipedia. We determined the highest search volume peaks to identify possible relation with online news headlines. No relation between incidence or prevalence of neurological disorders and the search volume for the related articles was found. Seven out of 10 neurological conditions showed relations in search volume peaks and news headlines. Six out of these seven peaks were related to news about famous people suffering from neurological disorders, especially those from showbusiness. Identification of discrepancies between disease burden and health seeking behavior on Wikipedia is useful in the planning of public health campaigns. Celebrities who publicly announce their neurological diagnosis might effectively promote awareness programs, increase public knowledge and reduce stigma related to diagnoses of neurological disorders.

  5. Cervical spinal canal narrowing and cervical neurologi-cal injuries

    Directory of Open Access Journals (Sweden)

    2012-04-01

    Full Text Available 【Abstract】Cervical spinal canal narrowing can lead to injury of the spinal cord and neurological symptoms in-cluding neck pain, headache, weakness and parasthesisas. According to previous and recent clinical researches, we investigated the geometric parameters of normal cervical spinal canal including the sagittal and transverse diameters as well as Torg ratio. The mean sagittal diameter of cervical spinal canal at C 1 to C 7 ranges from 15.33 mm to 20.46 mm, the mean transverse diameter at the same levels ranges from 24.45 mm to 27.00 mm and the mean value of Torg ratio is 0.96. With respect to narrow cervical spinal canal, the following charaterstics are found: firstly, extension of the cervical spine results in statistically significant stenosis as compared with the flexed or neutral positions; secondly, females sustain cervical spinal canal narrowing more easily than males; finally, the consistent narrowest cervical canal level is at C 4 for all ethnicity, but there is a slight variation in the sagittal diameter of cervical spinal stenosis (≤14 mm in Whites, ≤ 12 mm in Japanese, ≤13.7 mm in Chinese. Narrow sagittal cervical canal diameter brings about an increased risk of neurological injuries in traumatic, degenerative and inflam-matory conditions and is related with extension of cervical spine, gender, as well as ethnicity. It is hoped that this re-view will be helpful in diagnosing spinal cord and neuro-logical injuries with the geometric parameters of cervical spine in the future.

    1978-01-01

    Neurological, neuropsychological and neuroradiological studies were performed on 31 cases of the posterior cerebral artery (PCA) occlusion diagnosed by cerebral angiography and/or computed tomography (CT). Neurological examinations revealed visual field defect in 28 cases, contralateral sensory disturbance and hemiparesis in 23 cases and mental syndrome of memory disturbance, disorientation or confusion in 8 cases. CT was done on 17 cases out of 23 cases with contralateral sensory disturbance and hemiparesis. Ten cases of them revealed to have thalamic lesions by CT. In 7 cases which had no evidence of thalamic lesion by CT, 3 cases were highly suspected to have thalamic involvement clinically. The neurological and neuroradiological findings revealed high incidence and its pathomechanism of thalamic lesion in the cases of PCA occlusion. Neuropsychological examinations disclosed pure alexia in 6 cases, cortical blindness in 2 cases and hemispatial agnosia in 2 cases. Four cases with pure alexia were followed their alexic symptoms. Alexic symptoms lasted long in 3 cases. In these cases, collateral flow to the territory of the occlude PCA was hardly visible. One case with a relatively good collateral filling of the occluded PCA, alexic symptoms showed gradual improvement. Two cases with cortical blindness were proven to have bilateral PCA occlusion. In these 2 cases, collateral filling was hardly visible and their symptoms were permanent. The neurological and neuroradiological findings mentioned above suggest that the prognosis of pure alexia and cortical blindness depends largely on the degree of development of collateral circulation to the occluded PCA. Hemispatial agnosia was seen in 2 cases. (author)

    Hyperemesis gravidarum can impair correct absorption of an adequate amount of thiamine and can cause electrolyte imbalance. This study investigated the neurological complications in a pregnant woman with hyperemesis gravidarum. A 29-year-old pregnant woman was admitted for hyperemesis gravidarum. Besides undernutrition, a neurological examination disclosed weakness with hyporeflexia, ophthalmoparesis, multidirectional nystagmus and optic disks swelling; the patient became rapidly comatose. Brain MRI showed symmetric signal hyperintensity and swelling of periaqueductal area, hypothalamus and mammillary bodies, medial and posterior portions of the thalamus and columns of fornix, consistent with Wernicke encephalopathy (WE). Neurophysiological studies revealed an axonal sensory-motor polyneuropathy, likely due to thiamine deficiency or critical illness polyneuropathy. Sodium and potassium supplementation and parenteral thiamine were administered with improvement of consciousness state in a few days. WE evolved in Korsakoff syndrome. A repeat MRI showed a marked improvement of WE-related alterations and a new hyperintense lesion in the pons, suggestive of central pontine myelinolysis. No sign or symptom due to involvement of the pons was present.

  8. Neurologic manifestations of achondroplasia.

    Hecht, Jacqueline T; Bodensteiner, John B; Butler, Ian J

    2014-01-01

    Achondroplasia is the best described and most common form of the congenital short-limbed dwarfing conditions. Achondroplasia is apparent at birth and has a birth prevalence of 1 in 20000-30000 live-born infants. Achondroplasia is inherited as an autosomal dominant condition, although 80% of cases occur sporadically as new events in their families. Achondroplasia is caused, in virtually all of the cases, by a G380R mutation in fibroblast growth factor receptor 3 (FGFR3). Patients with achondroplasia should be evaluated by a multidisciplinary team of clinicians including geneticists, neurologists, and orthopedists, since there are numerous bony and neurological complications. The most severe complication results from craniocervical stenosis and medullary and upper spinal cord compression, which can have devastating and even lethal sequelae during early childhood. In subsequent decades, including adolescence, spinal cord and nerve compression are more prominent. The neurological complications of achondroplasia have been recognized in adults for more than a century and are attributed to bony defects, connective tissue structures, or both. Similar neurological complications are now appreciated in infants, young children, and teenagers with achondroplasia. Defective connective tissue elements in achondroplasia frequently lead to ligamentous laxity, which can aggravate the complications associated with bony stenosis. Bony abnormalities are known to cause neurological morbidity and lead to a shortened lifespan. Neurological complications associated with achondroplasia are reviewed, including recommendations for the evaluation and management of these clinical problems. © 2014 Elsevier B.V.

    Literature complements medical literature in the academic and clinical development of neurologists. The present article explores the contributions of writers of fiction on neurology. Literary works of fiction with particular reference to neurology. A symbiosis between writers of fiction and doctors has been well recognised. From Shakespeare to Cervantes by way of Dickens and Cela to writer - physicians such as Anton Chekhov or António Lobo Antunes have contributed through their medically informed literature to the better understanding of neurology. Some writers like Dostoevsky, Machado de Assis and Margiad Evans have written about their own experiences with disease thus bringing new insights to medicine. Furthermore, some neurological disorders have been largely based on literary descriptions. For instance, Dostoevsky's epilepsy has been retrospectively analysed by famous neurologists including Freud, Alajouanine or Gastaut, whilst his writings and biography have prompted others like Waxman and Geschwind to describe typical behavioural changes in temporal lobe epilepsy, finding their source of inspiration in Dostoevsky. Likewise, Cirignotta et al have named an unusual type of seizure after the Russian novelist. Inspired by Lewis Carroll, Todd introduced the term Alice in Wonderland Syndrome to refer to visual distortions generally associated with migraine. Writers of fiction offer a humanised perception of disease by contributing new insights into the clinical history, informing about the subjective experience of the illness and helping to eradicate the stigma associated to neurological disorders.

    Full Text Available Hashimoto%u2019s encephalopathy (HE is a rare disorder associated with autoimmune thyroiditis. Etiology of HE is not completely understood. High levels of serum antithyroid antibodies are seen in HE. Presentation with otoimmune thyroiditis, cognitive impairment, psychiatric and neurologic symptoms and absence of bacterial or viral enfections are characteristics of HE. HE is a steroid responsive encephalopathy. 60 years old male patient admitted to hospital with forget fulness continuing for 9 months and speech loss starting 2 days ago. Strong positivity of antithyroid antibodies increases the odds for HE. Thyroid function tests showed severe hypothyroidism. Electroencephalography and magnetic resonance imaging results were compatible with HE. HE is diagnosed with differantial diagnosis and exclusion of other reasons. This uncommon disorder is not recognised enough. High titres of serum antithyroid antiboides are always needed for diagnosis. Correct diagnosis requires awareness of wide range of cognitive and clinical presentations of HE.

    Parental depressive symptoms are associated with emotional and behavioural problems in offspring. However, genetically informative studies are needed to distinguish potential causal effects from genetic confounds, and longitudinal studies are required to distinguish parent-to-child effects from child-to-parent effects. We conducted cross-sectional analyses on a sample of Swedish twins and their adolescent offspring (n = 876 twin families), and longitudinal analyses on a US sample of children adopted at birth, their adoptive parents, and their birth mothers (n = 361 adoptive families). Depressive symptoms were measured in parents, and externalizing and internalizing problems measured in offspring. Structural equation models were fitted to the data. Results of model fitting suggest that associations between parental depressive symptoms and offspring internalizing and externalizing problems remain after accounting for genes shared between parent and child. Genetic transmission was not evident in the twin study but was evident in the adoption study. In the longitudinal adoption study child-to-parent effects were evident. We interpret the results as demonstrating that associations between parental depressive symptoms and offspring emotional and behavioural problems are not solely attributable to shared genes, and that bidirectional effects may be present in intergenerational associations.

    Neurologic disturbances including encephalopathy, seizures, and focal deficits complicate the course 10-30% of patients undergoing organ or stem cell transplantation. While much or this morbidity is multifactorial and often associated with extra-cerebral dysfunction (e.g., graft dysfunction, metabolic derangements), immunosuppressive drugs also contribute significantly. This can either be through direct toxicity (e.g., posterior reversible encephalopathy syndrome from calcineurin inhibitors such as tacrolimus in the acute postoperative period) or by facilitating opportunistic infections in the months after transplantation. Other neurologic syndromes such as akinetic mutism and osmotic demyelination may also occur. While much of this neurologic dysfunction may be reversible if related to metabolic factors or drug toxicity (and the etiology is recognized and reversed), cases of multifocal cerebral infarction, hemorrhage, or infection may have poor outcomes. As transplant patients survive longer, delayed infections (such as progressive multifocal leukoencephalopathy) and post-transplant malignancies are increasingly reported.

    Bee Venom (BV) has long been used in Korea to relieve pain symptoms and to treat inflammatory diseases, such as rheumatoid arthritis. The underlying mechanisms of the anti-inflammatory and analgesic actions of BV have been proved to some extent. Additionally, recent clinical and experimental studies have demonstrated that BV and BV-derived active components are applicable to a wide range of immunological and neurodegenerative diseases, including autoimmune diseases and Parkinson's disease. These effects of BV are known to be mediated by modulating immune cells in the periphery, and glial cells and neurons in the central nervous system. This review will introduce the scientific evidence of the therapeutic effects of BV and its components on several immunological and neurological diseases, and describe their detailed mechanisms involved in regulating various immune responses and pathological changes in glia and neurons.

Methods: Patients were collected retrospectively from Dr. Hasan Sadikin General Hospital Database from 2011–2013 with LHD, had neurological deficit such as radiculopathy and cauda equine syndrome for less than four weeks with a positive sign confirmed by neurological examination and confirmatory with MRI examination. Results: A total of 14 patients with lumbar herniated disc disease (10 males, 4 females suffered from progressive neurological deficit with an average age of (52.07±10.9 years old. Early disc height was 9.38±0.5 mm and progressive neurological deficit state disc height was 4.03±0.53 mm, which were significantly different statisticaly (p<0.01. Symptoms of radiculopathy were seen in 11 patients and cauda equine syndrome in three patients. Modic changes grade 1 was found in five patients, grade 2 in eight patients,grade 3 in one patient, Pfirmman grade 2 in eleven patients and grade 3 in three patients. Thecal sac compression 1/3 compression was seen in four patients and 2/3 compression in ten patients. Conclusions: Neurosurgeon should raise concerns on the characteristic changes of intervertebral disc in magnetic resonance imaging examination to avoid further neural injury in lumbar herniated disc patients.

  16. Dengue: a new challenge for neurology

    2012-11-01

    Full Text Available Dengue infection is a leading cause of illness and death in tropical and subtropical regions of the world. Forty percent of the world’s population currently lives in these areas. The clinical picture resulting from dengue infection can range from relatively minor to catastrophic hemorrhagic fever. Recently, reports have increased of neurological manifestations. Neuropathogenesis seems to be related to direct nervous system viral invasion, autoimmune reaction, metabolic and hemorrhagic disturbance. Neurological manifestations include encephalitis, encephalopathy, meningitis, Guillain-Barré syndrome, myelitis, acute disseminated encephalomyelitis, polyneuropathy, mononeuropathy, and cerebromeningeal hemorrhage. The development of neurological symptoms in patients with positive Immunoglobulin M (IgM dengue serology suggests a means of diagnosing the neurological complications associated with dengue. Viral antigens, specific IgM antibodies, and the intrathecal synthesis of dengue antibodies have been successfully detected in cerebrospinal fluid. However, despite diagnostic advancements, the treatment of neurological dengue is problematic. The launch of a dengue vaccine is expected to be beneficial.

  17. Neurological Disorders in Adult Celiac Disease

    2008-01-01

    Full Text Available Celiac disease may initially present as a neurological disorder. Alternatively, celiac disease may be complicated by neurological changes. With impaired nutrient absorption, different deficiency syndromes may occur and these may be manifested clinically with neurological changes. However, in patients with deficiency syndromes, extensive involvement of the small intestine with celiac disease is often evident. There are a number of reports of celiac disease associated with neuropathy, ataxia, dementia and seizure disorder. In these reports, there is no clear relationship with nutrient deficiency and a precise mechanism for the neurological changes has not been defined. A small number of patients have been reported to have responded to vitamin E administration, but most do not. In some, gluten antibodies have also been described, especially in those with ataxia, but a consistent response to a gluten-free diet has not been defined. Screening for celiac disease should be considered in patients with unexplained neurological disorders, including ataxia and dementia. Further studies are needed, however, to determine if a gluten-free diet will lead to improvement in the associated neurological disorder.

    Full Text Available Francisco Javier Carod-Artal1,21Neurology Department, Raigmore hospital, Inverness, UK; 2Universitat Internacional de Catalunya (UIC, Barcelona, Spain Abstract: Dengue is the most common mosquito-borne viral infection worldwide. There is increased evidence for dengue virus neurotropism, and neurological manifestations could make part of the clinical picture of dengue virus infection in at least 0.5%–7.4% of symptomatic cases. Neurological complications have been classified into dengue virus encephalopathy, dengue virus encephalitis, immune-mediated syndromes (acute disseminated encephalomyelitis, myelitis, Guillain–Barré syndrome, neuritis brachialis, acute cerebellitis, and others, neuromuscular complications (hypokalemic paralysis, transient benign muscle dysfunction and myositis, and dengue-associated stroke. Common neuro-ophthalmic complications are maculopathy and retinal vasculopathy. Pathogenic mechanisms include systemic complications and metabolic disturbances resulting in encephalopathy, direct effect of the virus provoking encephalitis, and postinfectious immune mechanisms causing immune-mediated syndromes. Dengue viruses should be considered as a cause of neurological disorders in endemic regions. Standardized case definitions for specific neurological complications are still needed.

  19. Neurologic sequelae associated with foscarnet therapy.

    Lor, E; Liu, Y Q

    1994-09-01

    To report three cases of possible foscarnet-induced neurologic sequelae. We report two cases of seizures and one case of hand cramping and finger paresthesia after starting foscarnet therapy with no evidence of predisposing risk factors, such as serum laboratory abnormalities, renal dysfunction, or known central nervous system (CNS) involvement. All three patients had stable laboratory values during therapy and when the neurologic adverse effects occurred. All patients were receiving appropriate dosages of foscarnet. The incidence of seizures in AIDS patients was reviewed. A history of CNS lesions, infections, and/or AIDS per se may increase the risk of a neurologic adverse effect while receiving foscarnet therapy. Acute ionized hypocalcemia may cause these neurologic adverse effects. Ionized hypocalcemia is transitory, is related to the rate of foscarnet infusion, and may not be reflected as a change in total serum calcium concentration. Foscarnet probably contributed to the neurologic adverse effects reported here. Foscarnet may need to be administered at a slower rate than is recommended by the manufacturer. Electrolytes must be monitored closely; however, a neurologic adverse effect may not be foreseen.

    Despite the fact that research has demonstrated consistent associations between self-rated measures of personality dimensions and mental disorders, little has been undertaken to investigate the relation between psychiatric symptoms and response patterns to self-rated tests. The aim of this study was to investigate the association between psychiatric symptoms and response quality using indices from our functional method. A sample of 1,784 participants from a Swiss population-based cohort completed a personality inventory (NEO-FFI) and a symptom checklist of 90 items (SCL-90-R). Different indices of response quality were calculated based on the responses given to the NEO-FFI. Associations among the responses to indices of response quality, sociodemographic characteristics and the SCL-90-R dimensions were then established. Psychiatric symptoms were associated with several important differences in response quality, questioning subjects' ability to provide valid information using self-rated instruments. As suggested by authors, psychiatric symptoms seem associated with differences in personality scores. Nonetheless, our study shows that symptoms are also related to differences in terms of response patterns as sources of differences in personality scores. This could constitute a bias for clinical assessment. Future studies could still determine whether certain subpopulations of subjects are more unable to provide valid information to self-rated questionnaires than others.

    2012-01-01

    Seasonal allergic rhinitis (SAR) symptoms are often most severe and/or disruptive during overnight and morning hours, resulting in cognitive/performance impairments and reduced quality of life throughout the following day. Surveys of allergy patients and health care practitioners reveal a common perception that intranasal steroids (INSs), many of which are dosed q.d., fail to adequately relieve symptoms for a full 24 hours. This review assessed whether perceptions of the 24-hour duration of action of INSs correspond with duration of action documented in clinical literature. SAR clinical trial literature of the last 5 years was reviewed to identify studies of INSs incorporating morning instantaneous (A.M. NOW) or instantaneous assessments of 24-hour duration of action. In numerous placebo-controlled trials of INSs in patients with SAR, treatment was associated with significantly greater improvements in A.M. NOW symptoms from baseline versus placebo. For congestion, this is noteworthy, because patients often cite this symptom, especially in the morning, as the most bothersome symptom. Comparison of A.M. NOW and daily scores suggests minimal drop in efficacy at 24 hours postdose. In several studies, INS treatment was found superior to intranasal or oral antihistamines in A.M. NOW symptom improvement. Once-daily INSs have potential for effective 24-hour symptom relief; however, there is an apparent disconnect between these findings and patient/physician perceptions. This discrepancy may be explained, in part, by less-than-ideal treatment adherence among "real-world" patients versus subjects treated in clinical trials. Proactive counseling can encourage proper INS use and help maximize treatment benefits.

    According to Beck's cognitive theory of depression, autonomy (high achievement concerns) and sociotropy (high interpersonal concerns) are vulnerability factors for depression when achievement or interpersonal stressors, respectively, are experienced. This hypothesis was tested among men and women attempting to quit smoking, an achievement stressor that can provoke depressive symptoms. Smokers recruited from the community (N=210) provided information about their quit attempt through mailed questionnaires. For the 48-h period following the quit, relationships among autonomy, sociotropy, coping, depressive symptoms and lapsing were assessed. Structural equation models supported the trait-congruence hypothesis because greater autonomy, but not sociotropy, was associated with elevated depressive symptoms among both men and women smokers. However, results were stronger for men (beta=.47, p=.0001) than for women (beta=.20, p=.05). After accounting for autonomy's relationship with depressive symptoms, greater autonomy was inversely associated with lapsing among men (beta=-.35, p=.01), but not women. Results point to the potential usefulness of a theoretical approach to understanding relationships between depressive symptoms and smoking cessation, and indicate that autonomous personality may be an important factor in smoking cessation in men.

    The authors present the case of a 6-year-old boy with a good neurological outcome from extreme hyponatraemia caused by autoimmune hypoadrenalism. He presented with 1 week of reduced appetite, lethargy, vomiting and one episode of diarrhoea. He was described as being slightly unsteady on his feet. Clinically he was alert, although intermittently confused, with dry mucous membranes and sunken eyes. Serum sodium was 96 mmol/l with normal serum potassium and renal function. He was initially treated with 3% saline intravenously, and his serum sodium increased to 128 mmol/l by day 3. He developed slurred speech and ataxia on day 4, although MRI brain showed no evidence of pontine myelinosis, and the symptoms resolved over 1 week. A Synacthen test on day 10 confirmed a diagnosis of Addison’s disease and he was commenced on hydrocortisone and fludrocortisone replacement therapy. At 5 months follow-up there are no obvious neurological or developmental sequelae. PMID:22679234

    Full Text Available Neurological disorders with a prolonged course, either remediable or otherwise are being seen increasingly in clinical practice and many such patients are young and are part of some organization or other wherein their services are needed if they were healthy and fit. The neurologists who are on the panel of these organizations are asked to certify whether these subjects are fit to work or how long they should be given leave. These certificates may be produced in the court of law and may be subjected to verification by another neurologist or a medical board. At present there are no standard guidelines in our country to effect such certification unlike in orthopedic specialty or in ophthalmology. The following is a beginning, based on which the neurologist can certify the neurological disability of such subjects and convey the same meaning to all neurologists across the country.

    Full Text Available Active immunization of children has been proven very effective in elimination of life threatening complications of many infectious diseases in developed countries. However, as vaccination-preventable infectious diseases and their complications have become rare, the interest focuses on immunization-related adverse reactions. Unfortunately, fear of vaccination-related adverse effects can led to decreased vaccination coverage and subsequent epidemics of infectious diseases. This review includes reports about possible side effects following vaccinations in children with neurological disorders and also published recommendations about vaccinating children with neurological disorders. From all international published data anyone can conclude that vaccines are safer than ever before, but the challenge remains to convey this message to society.

    Full Text Available Although proverb tests are commonly used in the mental status examination surprisingly little is known about either normal comprehension or the interpretation of proverbial expressions. Current proverbs tests have conceptual and linguistic shortcomings, and few studies have been done to investigate the specific effects of neurological and psychiatric disorders on the interpretation of proverbs. Although frontal lobes have traditionally been impugned in patients who are “concrete”, recent studies targeting deficient comprehension of non literal language (e.g. proverbs, idioms, speech formulas, and indirect requests point to an important role of the right hemisphere (RH. Research describing responses of psychiatrically and neurologically classified groups to tests of proverb and idiom usage is needed to clarify details of aberrant processing of nonliteral meanings. Meanwhile, the proverb test, drawing on diverse cognitive skills, is a nonspecific but sensitive probe of mental status.

    The optimal academic home for child neurology programs between adult neurology versus pediatric departments remains an open question. The Professors of Child Neurology, the national organization of child neurology department chairs, division chiefs, and training program directors, was surveyed to evaluate the placement of child neurology programs. Professors of Child Neurology members were surveyed regarding the placement of child neurology programs within adult neurology versus pediatric departments. Questions explored academic versus clinical lines of reporting and factors that may be advantages and disadvantages of these affiliations. Issues also addressed were the current status of board certification and number of clinics expected in academic child neurology departments. Of 120 surveys sent, 95 responses were received (79% response rate). The primary academic affiliation is in neurology in 54% of programs versus 46% in pediatrics, and the primary clinical affiliation is 45% neurology and 55% pediatrics. Advantages versus disadvantages of one's primary affiliation were similar whether the primary affiliation was in neurology or pediatrics. While 61% of respondents are presently board certified in pediatrics, only 2% of those with time-limited certification in general pediatrics plan to be recertified going forward. Typically six to eight half-day clinics per week are anticipated for child neurologists in academic departments without additional funding sources. Overall, leaders of child neurology departments and training programs would not change their affiliation if given the opportunity. Advantages and disadvantages associated with current affiliations did not change whether child neurology was located in neurology or pediatrics. Board certification by the American Board of Psychiatry and Neurology in child neurology is virtually universal, whereas pediatric board certification by the American Board of Pediatrics is being maintained by very few.

    Half of the adults in the United States use complementary and alternative medicine with mind-body therapy being the most commonly used form. Neurology patients often turn to their physicians for insight into the effectiveness of the therapies and resources to integrate them into their care. The objective of this article is to give a clinical overview of mind-body interventions and their applications in neurology. Medline and PsychInfo were searched on mind-body therapies and neurologic disease search terms for clinical trials and reviews and published evidence was graded. Meditation, relaxation, and breathing techniques, yoga, tai chi, and qigong, hypnosis, and biofeedback are described. Mind-body therapy application to general pain, back and neck pain, carpal tunnel syndrome, headaches, fibromyalgia, multiple sclerosis, epilepsy, muscular dysfunction, stroke, aging, Parkinson disease, stroke, and attention deficit-hyperactivity disorder are reviewed. There are several conditions where the evidence for mind-body therapies is quite strong such as migraine headache. Mind-body therapies for other neurology applications have limited evidence due mostly to small clinical trials and inadequate control groups.

    Patients with stroke can experience neurological deterioration in the prehospital setting. We evaluated patients with stroke to determine factors associated with prehospital neurological deterioration (PND). Among the Greater Cincinnati/Northern Kentucky region (population ~1.3 million), we screened all 15 local hospitals' admissions from 2010 for acute stroke and included patients aged ≥20. The GCS was compared between emergency medical services (EMS) arrival and hospital arrival, with decrease ≥2 points considered PND. Data obtained retrospectively included demographics, medical history and medication use, stroke subtype (eg, ischaemic stroke (IS), intracerebral haemorrhage (ICH), subarachnoid haemorrhage (SAH)) and IS subtype (eg, small vessel, large vessel, cardioembolic), seizure at onset, time intervals between symptom onset, EMS arrival and hospital arrival, EMS level of training, and blood pressure and serum glucose on EMS arrival. Of 2708 total patients who had a stroke, 1092 patients (median (IQR) age 74 (61-83) years; 56% women; 21% black) were analysed. PND occurred in 129 cases (12%), including 9% of IS, 24% of ICH and 16% of SAH. In multivariable analysis, black race, atrial fibrillation, haemorrhagic subtype and ALS level of transport were associated with PND. Haemorrhage and atrial fibrillation is associated with PND in stroke, and further investigation is needed to establish whether PND can be predicted. Further studies are also needed to assess whether preferential transport of patients with deterioration to hospitals equipped with higher levels of care is beneficial, identify why race is associated with deterioration and to test therapies targeting PND. © Article author(s) (or their employer(s) unless otherwise stated in the text of the article) 2018.

    Neurological injuries can be divided into those with traumatic and nontraumatic causes. The largest groups are traumatic brain injury (TBI) and nontraumatic stroke. TBI patients may present with intracranial hemorrhages (contusions, or subdural or epidural hematomas). Strokes are ischemic or hemorrhagic. In all these disorders, thrombosis and hemostasis play a major role. Treatment aims to either cease bleeding and/or restore perfusion. We reviewed hemostatic and thrombolytic therapies in patients with neurological injuries by MEDLINE and EMBASE search using various key words for neurological disorders and hemostatic therapies restricted to English language and human adults. Review of articles fulfilling inclusion criteria and relevant references revealed that, in patients with ischemic stroke, intravenous thrombolytic therapy with recombinant tissue plasminogen activator within 4.5-5 hours after onset of symptoms improves clinical outcome. In contrast, there are no hemostatic therapies that are proven to improve clinical outcome of patients with hemorrhagic stroke or TBI. In patients with hemorrhagic stroke who use vitamin K antagonist or direct oral anticoagulants, there is evidence that specific reversal therapies improve hemostatic laboratory parameters but without an effect on clinical recovery. In patients with hemorrhagic stroke or TBI who use concomitant antiplatelet therapy, there is evidence for harm of platelet transfusion. In patients with aneurysmal subarachnoid hemorrhage, tranexamic acid was shown to reduce rebleeding rate without improving clinical outcome. The effects of tranexamic acid in patients with TBI are still under investigation. We conclude that, in patients with ischemic stroke, thrombolytic therapy improves outcome when given within 4.5-5 hours. In hemorrhagic stroke and TBI, most hemostatic therapies improved or corrected laboratory parameters but not clinical outcome. Currently, in several trials, the effects of tranexamic acid are

  18. Evidence for Transdiagnostic Repetitive Negative Thinking and Its Association with Rumination, Worry, and Depression and Anxiety Symptoms: A Commonality Analysis

    Full Text Available Recent theoretical advances have emphasized the commonality between rumination and worry, often referred to as repetitive negative thinking. Although not studied extensively, repetitive negative thinking may not only account for a substantial overlap between depression and anxiety symptoms but also encapsulate other constructs including one’s tendency to experience unwanted intrusive thoughts or have low levels of mindfulness. In this study, 643 college students completed self-report questionnaire measures of repetitive negative thinking (the Habit Index of Negative Thinking and other relevant constructs including rumination, worry, depression and anxiety symptoms, intrusive thoughts, and mindfulness. To analyze the data, we conducted systematic commonality analyses, which algebraically decomposed shared variances among these measures into various unique components. Results in Study 1 indicated that individual differences in repetitive negative thinking were explained largely by the overlap between rumination and worry, but also by some rumination-specific and worry-specific variance. Moreover, the shared variation in rumination and worry explained the frequencies of depression and anxiety symptoms and their overlap. We also found in Study 2 that repetitive negative thinking was positively related to intrusive thoughts and negatively related to mindfulness. These associations were mostly explained by shared variance with rumination and worry, but there was also some mindfulness-specific variance. These results suggest that repetitive negative thinking may indeed lie at the core of the comorbidity between depression and anxiety symptoms, but that it is also a broader construct that encompasses intrusive thoughts and low levels of mindfulness.

    A relatively small number of studies have been dedicated to the differential effects of the current mood state on cognition in patients with a bipolar disorder (BD). The aim of the current study was to investigate the effect of current mood state on divided attention (DA) performance, and specifically examine possible beneficial effects of the (hypo-) manic state. Over a maximum period of 24 months, medication use, divided attention test (a subtest of the Test for Attentional Performance (TAP)) was assessed every 6 months in 189 outpatients with BD. Data were analyzed with multilevel regression analysis (i.e. linear mixed models). DA performance varied considerable over time within patients. Corrected for psychotropic medication a significant quadratic relationship between manic symptoms and DA performance was found, with mild hypomanic symptoms having a positive influence on divided attention scores and moderate to severe manic symptoms having a negative influence. No association between depressive symptoms and DA performance was found. In future research on mania and cognition as well as in the clinical practice both the beneficial and negative effects of mania should be taken into account. Copyright © 2014 Elsevier Ireland Ltd.

    Acknowledging separable factors underlying negative symptoms may lead to better understanding and treatment of negative symptoms in individuals with schizophrenia. The current study aimed to test whether the negative symptoms factor (NSF) of the Positive and Negative Syndrome Scale (PANSS) would be better represented by expressive and experiential deficit factors, rather than by a single factor model, using confirmatory factor analysis (CFA). Two hundred and twenty individuals with schizophrenia spectrum disorders completed the PANSS; subsamples additionally completed the Brief Negative Symptom Scale (BNSS) and the Motivation and Pleasure Scale-Self-Report (MAP-SR). CFA results indicated that the two-factor model fit the data better than the one-factor model; however, latent variables were closely correlated. The two-factor model's fit was significantly improved by accounting for correlated residuals between N2 (emotional withdrawal) and N6 (lack of spontaneity and flow of conversation), and between N4 (passive social withdrawal) and G16 (active social avoidance), possibly reflecting common method variance. The two NSF factors exhibited differential patterns of correlation with subdomains of the BNSS and MAP-SR. These results suggest that the PANSS NSF would be better represented by a two-factor model than by a single-factor one, and support the two-factor model's adequate criterion-related validity. Common method variance among several items may be a potential source of measurement error under a two-factor model of the PANSS NSF.

    Full Text Available Abstract Background Dysphagia and feeding intolerance are common in neurologically handicapped children. The aim is to determine the etiologies of feeding intolerance in neurologically handicapped children who are intolerant of tube feedings. Methods Eighteen neurologically handicapped children, followed in the Tube Feeding Clinic at the Children's Hospital of Wisconsin who were intolerant of gastrostomy feedings. The charts of these 18 patients were reviewed. Past medical history, diagnoses, history of fundoplication and results of various tests of gastrointestinal function including barium contrast radiography, endoscopy and antroduodenal manometry were documented. Results Five of 11 children had abnormal barium upper gastrointestinal series. Seven of 14 had abnormal liquid phase gastric emptying tests. Two of 16 had esophagitis on endoscopy. All 18 children had abnormal antroduodenal motility. Conclusions In neurologically handicapped children foregut dysmotility may be more common than is generally recognized and can explain many of the upper gastrointestinal symptoms in neurologically handicapped children.

    The First World War was a global war, beginning on 28 July 1914, until 11 November 1918. Soon after the beginning of the war, there was an "epidemic" of neurological conversion symptoms. Soldiers on both sides started to present in large numbers with neurological symptoms, such as dizziness, tremor, paraplegia, tinnitus, amnesia, weakness, headache and mutism of psychosomatic origin. This condition was known as shell shock, or "war neurosis". Because medically unexplained symptoms remain a major challenge, and considering the close relationship of symptoms described in shell shock with clinical neurology, we should study their history in order to improve future care.

    Full Text Available During a clinical examination of children with autistic spectrum disorders, attention should be drawn to both their major clinical manifestations and neurological comorbidities. The paper considers the mechanisms of autism-induced neurological disorders, the spectrum of which may include manifestations, such as retarded and disharmonic early psychomotor development; the specific features of sensory perception/processing; rigidity and monotony of motor and psychic reactions; motor disinhibition and hyperexcitability; motor stereotypies; uncoordinated movements; developmental coordination disorders (dyspraxia; impaired expressive motor skills; speech and articulation disorders; tics; epilepsy. It describes the specific features of neurological symptoms in Asperger’s syndrome, particularly in semantic-pragmatic language disorders, higher incidence rates of hyperlexia, motor and vocal tics. The incidence rate of epilepsy in autistic spectrum disorders is emphasized to be greater than the average population one. At the same time, the risk of epilepsy is higher in mentally retarded patients with autism. Identification of neurological disorders is of great importance in determining the tactics of complex care for patients with autistic spectrum disorders.

    Several surgical treatments can be employed for the patients with neurological disorders, such as multiple sclerosis, Guillain-Barré syndrome, Parkinson's disease, amyotrophic lateral sclerosis, Alzheimer disease and spinal cord injury. It is possible that anesthesia related complications are induced in these neurologically complicated patients in the perioperative period. Respiratory dysfunction and autonomic nervous system dysfunction are most common in this population. Respiratory muscle weakness and bulbar palsy may cause aspiration pneumonia. Sometimes, postoperative ventilatory support is mandatory in these patients. Autonomic nervous system dysfunction may cause hypotension secondary to postural changes, blood loss, or positive airway pressure. Some therapeutic agents prescribed for neurological symptoms have drug interaction with anesthetic agents. Patients with motor neuron disease should be considered to be vulnerable to hyperkalemia in response to a depolarizing muscle relaxant. Although perioperative treatment guideline for most neurologic disorders has not been reported to lessen perioperative morbidity, knowledge of the clinical features and the interaction of common anesthetics with the drug therapy is important in planning intraoperative and postoperative management.

    Eclampsia is one of the most common acute neurological events occurring during pregnancy. However, there are many other conditions that can present during pregnancy and the puerperium and that may either mimic eclampsia or produce other acute neurological manifestations. Frequently the symptoms and signs are non-specific, and it can be difficult to differentiate between these conditions on clinical grounds alone. Neuroradiological studies can provide valuable diagnostic information, and interventional radiological procedures may play a part in the subsequent management of these conditions. This review focuses on the imaging of acute neurological conditions which may be associated with, or present during, pregnancy and the puerperium

    Although low muscle function/strength is an important predictor of poor clinical outcome in older patients, information on its impact on mental health in clinical practice is still lacking. The aim of this report is to measure the impact of low muscle function measured by handgrip strength on mental health of older people during both acute illness and recovery. Four hundred and thirty-two randomly selected hospitalized older patients had their baseline demographic and clinical characteristics assessed within 72 h of admission, at 6 weeks and at 6 months. Low muscle strength-handgrip was defined using the European Working Group criteria. Mental health outcome measures including cognitive state, depression symptoms and quality of life were also measured. Among the 432 patients recruited, 308 (79%) had low muscle strength at baseline. Corresponding figures at 6 weeks and at 6 months were 140 (73%) and 158 (75%). Patients with poor muscle strength were significantly older with increased disability and poor nutritional status compared with those with normal muscle strength. After adjustment for age, gender, disability, comorbidity including severity of acute illness and body mass index patients with low muscle strength had worse cognitive function, quality of life and higher depression symptoms compared with those with normal muscle strength over a 6-month period (p older people is associated with poor cognitive state and quality of life and increased depression symptoms during both acute illness and recovery.

    Cross-sectional research suggests that individuals at risk for internalizing disorders show differential activation levels and/or dynamics of stress-sensitive physiological systems, possibly reflecting a process of stress sensitization. However, there is little longitudinal research to clarify how the development of these systems over time relates to activation during acute stress, and how aspects of such activation map onto internalizing symptoms. We investigated children's (n = 107) diurnal hypothalamic-pituitary-adrenal activity via salivary cortisol (morning and evening levels) across 29 assessments spanning 6+ years, and related longitudinal patterns to acute stress responses at the end of this period (age 9-10). Associations with child psychiatric symptoms at age 10 were also examined to determine internalizing risk profiles. Increasing morning cortisol levels across assessments predicted less of a cortisol decline following interpersonal stress at age 9, and higher cortisol levels during performance stress at age 10. These same profiles of high and/or sustained cortisol elevation during psychosocial stress were associated with child anxiety symptoms. Results suggest developmental sensitization to stress-reflected in rising morning cortisol and eventual hyperactivation during acute stress exposure-may distinguish children at risk for internalizing disorders.

    Full Text Available West Nile virus infection in humans is mostly asymptomatic. Less than 1% of neuro-invasive cases show a fatality rate of around 10%. Acute flaccid paralysis of respiratory muscles leading to respiratory failure is the most common cause of death. Although the peripheral nervous system can be involved, isolated phrenic nerve palsy leading to respiratory failure is rare and described in only two cases in the English literature. We present another case of neurological respiratory failure due to West Nile virus-induced phrenic nerve palsy. Our case reiterates the rare, but lethal, consequences of West Nile virus infection, and the increase of its awareness among physicians.

    Objective: To survey US-trained graduating neurology residents who are American Academy of Neurology members, in an effort to trend perceived quality and completeness of graduate neurology education. Methods: An electronic survey was sent to all American Academy of Neurology members graduating from US neurology residency programs in the Spring of 2014. Results: Of 805 eligible respondents, 24% completed the survey. Ninety-three percent of adult neurology residents and 56% of child neurology residents reported plans to pursue fellowship training after residency. Respondents reported a desire for additional training in neurocritical care, neuro-oncology, neuromuscular diseases, botulinum toxin injection, and nerve blocks. There remains a clear deficit in business training of neurology residents, although there was notable improvement in knowledge of coding and office management compared to previous surveys. Discussion: Although there are still areas of perceived weakness in neurology training, graduating neurology residents feel generally well prepared for their chosen careers. However, most still pursue fellowship training for reasons that are little understood. In addition to certain subspecialties and procedures, practice management remains deficient in neurology training and is a point of future insecurity for most residents. Future curriculum changes should consider resident-reported gaps in knowledge, with careful consideration of improving business training. PMID:26976522

    The objective of this review was to update evidence-based medicine recommendations for treating motor symptoms of Parkinson's disease (PD). The Movement Disorder Society Evidence-Based Medicine Committee recommendations for treatments of PD were first published in 2002 and updated in 2011, and we continued the review to December 31, 2016. Level I studies of interventions for motor symptoms were reviewed. Criteria for inclusion and quality scoring were as previously reported. Five clinical indications were considered, and conclusions regarding the implications for clinical practice are reported. A total of 143 new studies qualified. There are no clinically useful interventions to prevent/delay disease progression. For monotherapy of early PD, nonergot dopamine agonists, oral levodopa preparations, selegiline, and rasagiline are clinically useful. For adjunct therapy in early/stable PD, nonergot dopamine agonists, rasagiline, and zonisamide are clinically useful. For adjunct therapy in optimized PD for general or specific motor symptoms including gait, rivastigmine is possibly useful and physiotherapy is clinically useful; exercise-based movement strategy training and formalized patterned exercises are possibly useful. There are no new studies and no changes in the conclusions for the prevention/delay of motor complications. For treating motor fluctuations, most nonergot dopamine agonists, pergolide, levodopa ER, levodopa intestinal infusion, entacapone, opicapone, rasagiline, zonisamide, safinamide, and bilateral STN and GPi DBS are clinically useful. For dyskinesia, amantadine, clozapine, and bilateral STN DBS and GPi DBS are clinically useful. The options for treating PD symptoms continues to expand. These recommendations allow the treating physician to determine which intervention to recommend to an individual patient. © 2018 International Parkinson and Movement Disorder Society. © 2018 International Parkinson and Movement Disorder Society.

    Full Text Available ABSTRACT The epidemics of Chikungunya virus (CHIKV and Zika virus (ZIKV infections have been considered the most important epidemiological occurrences in the Americas. The clinical picture of CHIKV infection is characterized by high fever, exanthema, myalgia, headaches, and arthralgia. Besides the typical clinical picture of CHIKV, atypical manifestations of neurological complications have been reported: meningo-encephalitis, meningoencephalo-myeloradiculitis, myeloradiculitis, myelitis, myeloneuropathy, Guillain-Barré syndrome and others. The diagnosis is based on clinical, epidemiological, and laboratory criteria. The most common symptoms of ZIKV infection are skin rash (mostly maculopapular, fever, arthralgia, myalgia, headache, and conjunctivitis. Some epidemics that have recently occurred in French Polynesia and Brazil, reported the most severe conditions, with involvement of the nervous system (Guillain-Barré syndrome, transverse myelitis, microcephaly and meningitis. The treatment for ZIKV and CHIKV infections are symptomatic and the management for neurological complications depends on the type of affliction. Intravenous immunoglobulin, plasmapheresis, and corticosteroid pulse therapy are options.

    Body dysmorphic disorder (BDD) is thought to be etiologically related to obsessive-compulsive disorder (OCD) but the available evidence is incomplete. The current study examined the genetic and environmental sources of covariance between body dysmorphic and obsessive-compulsive symptoms in a community sample of adult twins. A total of 2,148 female twins (1,074 pairs) completed valid and reliable measures of body dysmorphic concerns and obsessive-compulsive symptoms. The data were analyzed using bivariate twin modeling methods and the statistical programme Mx. In the best-fitting model, the covariation between body dysmorphic and obsessive-compulsive traits was largely accounted for by genetic influences common to both phenotypes (64%; 95% CI: 0.50-0.80). This genetic overlap was even higher when specific obsessive-compulsive symptom dimensions were considered, with up to 82% of the phenotypic correlation between the obsessing and symmetry/ordering symptom dimensions and dysmorphic concerns being attributable to common genetic factors. Unique environmental factors, although influencing these traits individually, did not substantially contribute to their covariation. The results remained unchanged when excluding individuals reporting an objective medical condition/injury accounting for their concern in physical appearance. The association between body dysmorphic concerns and obsessive-compulsive symptoms is largely explained by shared genetic factors. Environmental risk factors were largely unique to each phenotype. These results support current recommendations to group BDD together with OCD in the same DSM-5 chapter, although comparison with other phenotypes such as somatoform disorders and social phobia is needed.

    Based upon an analysis of 6 major historical technological advances over the last 150 years, a new syndrome, disruptive technology disorder (DTD), is introduced. DTD describes the human health ailments that accompany the implementation of disruptive technologies. Elevator sickness, railway spine, and bicycle face are representative examples. Though the underlying causative disruptive technologies may differ, many neurologic symptoms (headache, dizziness, weakness) are common to multiple DTDs. Born of technology-driven societal change, DTDs manifest as a complex interplay between biological and psychological symptoms. © 2017 American Academy of Neurology.

    A common problem faced by neurologists is the existence of disorders that present with neurological symptoms but do not have identifiable neurological bases. Conversion disorder is the most common of these disorders. In some situations, members of a cohesive social group will develop the same or similar symptoms. This review discusses conversion disorder in children, with an emphasis on function movement disorders. It also reviews a recent occurrence of mass psychogenic illness in New York State with discussion of the key features of mass psychogenic illness. © 2013 New York Academy of Sciences.

    2007-10-01

    Full Text Available Abstract Background By mid adolescence there is an excess in female physical and/or psychosomatic, as well as psychological morbidity. This paper examines the contribution of a range of factors (self-esteem, body image, gender-role orientation, body mass index, smoking and physical activity to explaining the female excess in three psychosomatic symptoms (headaches, stomach ache/sickness, and dizziness and depressive mood at age 15. Methods A cohort of 2,196 school pupils (analyses restricted to 2,005 with complete data surveyed at age 15. All measures were obtained via self-completion questionnaires, apart from body mass index, derived from measured height and weight. Analyses examined (a sex differences in each potential explanatory factor; (b their associations with the health measures; (c the effect of adjustment for these factors on sex differences in the health measures; and (d the existence of interactive effects between sex and the explanatory factors on the health measures Results Each potential explanatory factor was significantly differentiated by sex. Self-esteem, body image (represented by weight-related worries, smoking and physical activity were related to the health measures. These factors accounted for one third of the female excess in headaches and stomach problems, half the excess in dizziness and almost all that in respect of depressive mood. Self-esteem and body image were the factors most consistently related to health, and adjustment for these resulted in the largest reductions in the odds of a female excess in both the psychosomatic symptoms and depressive mood. Conclusion Adjustment for a range of potential psychosocial and behavioural factors largely explains (statistically excess female depressive mood. These factors also partially explain the female excess in certain psychosomatic symptoms.

    A possible role of vitamin D in depression has received considerable attention, especially given the significant disability, mortality, and healthcare costs associated to depression and the high prevalence of vitamin D deficiency. We investigated the cross-sectional associations between serum 25-hydroxyvitamin D (25OHD) levels and depressive symptoms (CES-D) in 5,607 older adults from the English Longitudinal Study of Ageing (ELSA). Overall, there was a significant association between low 25OHD levels and elevated depressive symptoms (odds ratio [OR] = 1.58, 95% confidence interval [CI] = 1.20-2.07 for the lowest quartile; OR = 1.45, 95% CI = 1.15-1.83 for <30 nmol/L cut-off and OR = 1.34, 95% CI = 1.10-1.62 for the ≤50 nmol/L cut-off) after adjustment for a wide range of covariates of clinical significance. Fully adjusted models showed that women in the lowest (OR = 1.67, 95% CI = 1.20-2.34) and second lowest (OR = 1.68, 95% CI = 1.20-2.35) quartiles of 25OHD as well as those with 25OHD levels <30 nmol/L (OR = 1.40, 95% CI = 1.06-1.86) and ≤50 nmol/L (OR = 1.35, 95% CI = 1.07-1.72) were more likely to report elevated depressive symptoms. For men, however, this association only remained significant for those with 25OHD levels of <30 nmol/L (OR = 1.60, 95% CI = 1.06-2.42) in the fully adjusted models. The independent and inverse association found between low 25OHD levels and elevated depressive symptoms suggests that vitamin D deficiency may be a risk factor for late-life depression, particularly among women. Whether our findings have any clinical meaning or not, additional data are needed from well-designed randomized controlled trials of vitamin D for the prevention and treatment of late-life depression. © The Author 2017.

  6. Cognitive style and depressive symptoms in elderly people - extending the empirical evidence for the cognitive vulnerability-stress hypothesis.

    Depression is common in older people and its identification and treatment has been highlighted as one of the major challenges in an ageing world. Poor physical and cognitive health, bereavement, and prior depression are important risk factors for depression in elderly people. Attributional or cognitive style has been identified as a risk factor for depression in children, adolescents and younger adults but its relevance for depression and mood in elderly people has not been investigated in the context of other risk factors. Sixty-four older adults from an 'extra care' living scheme (aged 59-97) were recruited for a 6-week prospective study to examine the relationships between cognitive style and depressive symptoms. Regression analyses revealed that, when other risk factors were controlled for, cognitive style and its interaction with stress predicted changes in depressive symptoms, therefore partially replicating prior research. Cognitive-stress-vulnerability models also apply to elderly populations, but may be rather predictive of changes in depression when facing lower levels of stress. Copyright 2010 Elsevier Ltd.

    The aim of the present study was to determine whether patients with borderline personality disorder (BPD) show any neurological soft signs compared to healthy controls. Furthermore we sought to examine the role of common symptoms related to BPD, such as depression, anxiety or impulsivity, in association with neurological soft signs. Thirty patients with borderline personality disorder and thirty hospital-based controls were examined for neurological soft signs. The total score of neurological soft signs in BPD was significantly higher than controls. In terms of subscales, patients had higher scores in Sensory Integration and Motor Coordination and other neurological soft signs compared to control group. Multiple regression analysis showed that the impulsivity score was the best significant predictor of neurological soft signs in BPD. The increase of neurological soft signs in patients with BPD may address a non-focal neurological dysfunction in borderline personality disorder. Copyright © 2016 Elsevier Ireland Ltd.

    During the past ten years, an increasing number of controlled studies have assessed the potential rehabilitative effects of music-based interventions, such as music listening, singing, or playing an instrument, in several neurological diseases. Although the number of studies and extent of available evidence is greatest in stroke and dementia, there is also evidence for the effects of music-based interventions on supporting cognition, motor function, or emotional wellbeing in people with Parkinson's disease, epilepsy, or multiple sclerosis. Music-based interventions can affect divergent functions such as motor performance, speech, or cognition in these patient groups. However, the psychological effects and neurobiological mechanisms underlying the effects of music interventions are likely to share common neural systems for reward, arousal, affect regulation, learning, and activity-driven plasticity. Although further controlled studies are needed to establish the efficacy of music in neurological recovery, music-based interventions are emerging as promising rehabilitation strategies.

    Neurophobia (fear of neural sciences) and evaluation of independent sector contracts in neurology have seldom been examined among general practitioners (GPs). A questionnaire determined GPs' perceptions of neurology compared with other medical specialties. GP experiences of neurology services with independent sector companies and the local National Health Service (NHS) were compared. Areas of potential improvement in NHS neurology services were recorded from thematic analyses. Among 76 GPs neurology was perceived to be as interesting as other medical specialties. GPs reported less knowledge, more difficulty and less confidence in neurology compared with other medical specialties. There was a preference for a local NHS neurology service (pneurology services provided better patient satisfaction. GPs prefer local NHS neurology services to independent sector contracts. GPs' evaluations should inform commissioning of neurology services. Combating neurophobia should be an integral part of responsive commissioning. Published by the BMJ Publishing Group Limited.

  10. [Neurological and psychiatric aspects of some gastrointestinal diseases].

    Aszalós, Zsuzsa

    2008-11-02

    The gastrointestinal tract is controlled by the independent enteric nervous system. It is also closely connected to the central nervous system, and bi-directional communication exists between them. The communication involves neural pathways as well as immune and endocrine mechanisms. The brain-gut axis plays a prominent role in the modulation of gut functions. Signals from different sources (e.g. sound, sight, smell, somatic and visceral sensations, pain) reach the brain. These inputs are modified by memory, cognition and affective mechanisms and integrated within the neural circuits of the central nervous system, spinal cord, autonomic and enteral nervous systems. These inputs can have physiologic effects, such as changes in motility, secretion, immune function, and blood flow to the gastrointestinal tract. One of the most important neurotransmitters is serotonin that plays a key role in the pathogenesis of the most common chronic functional gastrointestinal disorder: the irritable bowel syndrome. It is a biopsychosocial disease, resulting from the dysregulation of the brain-gut axis. Endogenous pain facilitation rather than inhibition, pathologic gradation of visceral perception and reduced threshold for pain are all evident in these patients. Abuse history is common in their anamnesis. Exaggerated conscientiousness, perfectionism, oversensitivity, feeling of deficiency in effectiveness, and higher demand for social parity, neuroticism and alexithymia have been detected among their constant personality features. Females are also characterized by gender role conflict and low assertiveness. Antidepressants and psychotherapy have important roles in their treatment. Also patients with inflammatory bowel disease are characterized by neuroticism and alexithymia and altered mother-child attachment is often described in their anamnesis. Autonomic neuropathy is a frequent and early neurological complication. Reflux disease and obstructive sleep apnea mutually generate

    Thallium intoxication was reported in cases with accidental ingestion, suicide attempt, and criminal adulteration. Reported cases were mostly one-time ingestion, therefore, the clinical course of divisional ingestion has not been fully known. Here, we report a case with two-step thallium intoxication manifesting as tardily accelerated neurologic deterioration. A 16-year-old adolescent was cryptically poisoned with thallium sulfate twice at an interval of 52days. After the first ingestion, neurologic symptoms including visual loss, myalgia, and weakness in legs developed about 40days after the development of acute gastrointestinal symptoms and alopecia. After the second ingestion, neurologic symptoms deteriorated rapidly and severely without gastrointestinal or cutaneous symptoms. Brain magnetic resonance imaging exhibited bilateral optic nerve atrophy. Nerve conduction studies revealed severe peripheral neuropathies in legs. Thallium intoxication was confirmed by an increase in urine thallium egestion. Most of the neurologic manifestations ameliorated in two years, but the visual loss persisted. The source of thallium ingestion was unraveled afterward because a murder suspect in another homicidal assault confessed the forepast adulteration. This discriminating clinical course may be attributable to the cumulative neurotoxicity due to the longer washout-time of thallium in the nervous system than other organs. It is noteworthy that the divisional thallium intoxication may manifest as progressive optic and peripheral neuropathy without gastrointestinal or cutaneous symptoms. Copyright © 2016 Elsevier Ltd.

    1993-11-12

    The possibility that previous occupational exposure to solvents might be associated with clinically significant neurological dysfunction in older adults was investigated in a cross-sectional study. Subjects included 67 painters, 22 aerospace painters and fuel cell sealers, and a comparison group of 126 carpenters. All subjects had retired from regular employment at least 1 year prior to the study. As measured by semiquantitative exposure index, the cumulative histories of lifetime occupational solvent exposure were on the average comparable in the two exposed study groups, painters and aerospace workers. The carpenters differed from the other groups in solvent exposure by several orders of magnitude. The painters had a significantly higher history of consuming alcoholic beverages than did the other two study groups. The painters had a significantly higher score on the Beck Depression Inventory, a measure of current depressive symptoms. The painters reported significantly more general neurologic symptoms than did the other two groups. The aerospace workers showed much greater evidence of possible adverse effects from former solvent exposure on current neuropsychological function than did the painters when determined by reasoning and memory tests, memory visual motor speed and motor tests. No evidence of persistent effects on liver or renal excretory function was seen in solvent exposed subjects.

    The treatment of agitation and aggression, typical Behavioural and Psychological Symptoms of Dementia (BPSDs) of Alzheimer's Disease (AD), is one of the most complicated aspects of handling patients suffering from dementia. Currently, the management of these symptoms often associated with an increased pain perception, which notably reduces the patients' quality of life (QoL), relies on the employment of antipsychotic drugs. Unfortunately, the use of these pharmacological agents has some limits: in the long term, they do not result in being equally effective as in the first weeks of treatment and they present important side effects. Therefore, there is growing interest, supported by clinical evidence, in aromatherapy for the control of agitation, aggression, and psychotic symptoms. Some molecular mechanisms have been proposed to explain the behavioural effects of essential oils, as the whole phytocomplex or the single components, but important basic research effort is still needed. For this reason, rigorous preclinical studies are necessary in order to understand the pharmacological basis of aromatherapy in the treatment of BPSDs and to widen the cluster of effective essential oils in pharmacotherapeutic practice.

    1993-12-01

    There has been remarkable progress in the identification of mutations in genes that cause inherited neurological disorders. Abnormalities in the genes for Huntington disease, neurofibromatosis types 1 and 2, one form of familial amyotrophic lateral sclerosis, fragile X syndrome, myotonic dystrophy, Kennedy syndrome, Menkes disease, and several forms of retinitis pigmentosa have been elucidated. Rare disorders of neuronal migration such as Kallmann syndrome, Miller-Dieker syndrome, and Norrie disease have been shown to be due to specific gene defects. Several muscle disorders characterized by abnormal membrane excitability have been defined as mutations of the muscle sodium or chloride channels. These advances provide opportunity for accurate molecular diagnosis of at-risk individuals and are the harbinger of new approaches to therapy of these diseases.

    Full Text Available Nervous system lesions associated with chronic alcohol intoxication are common in clinical practice. They lead to aggravated alcoholic disease, its more frequent recurrences, and intensified pathological craving for alcohol. Neurological pathology in turn occurs with frequent exacerbations. The interaction of diseases, age, and medical  pathomorphism modifies the clinical presentation and course of the  major pathology, as well as comorbidity, the nature and severity of  complications, worsens quality of life in a patient, and makes the  diagnostic and treatment process difficult. The paper discusses the  classification, clinical variants, biochemical and molecular biological  aspects of various complications of alcoholic disease. It considers its  most common form, in particular alcoholic polyneuropathy, as well as its rarer variants, such as hemorrhagic encephalopathy with a subacute course (Gayet–Wernicke encephalopathy.

    The significance of deja vu is widely recognised in the context of temporal lobe epilepsy, and enquiry about deja vu is frequently made in the clinical assessment of patients with possible epilepsy. Deja vu has also been associated with several psychiatric disorders. The historical context of current understanding of deja vu is discussed. The literature reveals deja vu to be a common phenomenon consistent with normality. Several authors have suggested the existence of a "pathological" form of deja vu that differs, qualitatively or quantitatively, from "non-pathological" deja vu. The features of deja vu suggesting neurological or psychiatric pathology are discussed. Several neuroanatomical and psychological models of the deja vu experience are highlighted, implicating the perceptual, mnemonic and affective regions of the lateral temporal cortex, hippocampus and amygdala in the genesis of deja vu. A possible genetic basis for a neurochemical model of deja vu is discussed. Clinical approaches to the patient presenting with possible deja vu are proposed.

  20. THE KETOGENIC DIET AS A TREATMENT PARADIGM FOR DIVERSE NEUROLOGICAL DISORDERS

    Directory of Open Access Journals (Sweden)

    2012-04-01

    Full Text Available Dietary and metabolic therapies have been attempted in a wide variety of neurological diseases, including epilepsy, headache, neurotrauma, Alzheimer disease, Parkinson disease, sleep disorders, brain cancer, autism, pain, and multiple sclerosis. The impetus for using various diets to treat – or at least ameliorate symptoms of – these disorders stems from both a lack of effectiveness of pharmacological therapies, and also the intrinsic appeal of implementing a more natural treatment. The enormous spectrum of pathophysiological mechanisms underlying the aforementioned diseases would suggest a degree of complexity that cannot be impacted universally by any single dietary treatment. Yet, it is conceivable that alterations in certain dietary constituents could affect the course and impact the outcome of these brain disorders. Further, it is possible that a final common neurometabolic pathway might be influenced by a variety of dietary interventions. The most notable example of a dietary treatment with proven efficacy against a neurological condition is the high-fat, low-carbohydrate ketogenic diet (KD used in patients with medically intractable epilepsy. While the mechanisms through which the KD works remain unclear, there is now compelling evidence that its efficacy is likely related to the normalization of aberrant energy metabolism. The concept that many neurological conditions are linked pathophysiologically to energy dysregulation could well provide a common research and experimental therapeutics platform, from which the course of several neurological diseases could be favorably influenced by dietary means. Here we provide an overview of studies using the KD in a wide panoply of neurologic disorders in which neuroprotection is an essential component.

  1. Neurology of ciguatera

    Science.gov (United States)

    Pearn, J

    2001-01-01

    Ciguatera is a widespread ichthyosarcotoxaemia with dramatic and clinically important neurological features. This severe form of fish poisoning may present with either acute or chronic intoxication syndromes and constitutes a global health problem. Ciguatera poisoning is little known in temperate countries as a potentially global problem associated with human ingestion of large carnivorous fish that harbour the bioaccumulated ciguatoxins of the photosynthetic dinoflagellate Gambierdiscus toxicus. This neurotoxin is stored in the viscera of fish that have eaten the dinoflagellate and concentrated it upwards throughout the food chain towards progressively larger species, including humans. Ciguatoxin accumulates in all fish tissues, especially the liver and viscera, of "at risk" species. Both Pacific (P-CTX-1) and Caribbean (C-CTX-1) ciguatoxins are heat stable polyether toxins and pose a health risk at concentrations above 0.1 ppb. The presenting signs of ciguatera are primarily neurotoxic in more than 80% of cases. Such include the pathognomonic features of postingestion paraesthesiae, dysaesthesiae, and heightened nociperception. Other sensory abnormalities include the subjective features of metallic taste, pruritis, arthralgia, myalgia, and dental pain. Cerebellar dysfunction, sometimes diphasic, and weakness due to both neuropathy and polymyositis may be encountered. Autonomic dysfunction leads to hypotension, bradycardia, and hypersalivation in severe cases. Ciguatoxins are potent, lipophilic sodium channel activator toxins which bind to the voltage sensitive (site 5) sodium channel on the cell membranes of all excitable tissues. Treatment depends on early diagnosis and the early administration of intravenous mannitol. The early identification of the neurological features in sentinel patients has the potential to reduce the number of secondary cases in cluster outbreaks.

    The first African Child Neurology Association meeting identified key challenges that the continent faces to improve the health of children with neurology disorders. The capacity to diagnose common neurologic conditions and rare disorders is lacking. The burden of neurologic disease on the continent is not known, and this lack of knowledge limits the ability to lobby for better health care provision. Inability to practice in resource-limited settings has led to the migration of skilled professionals away from Africa. Referral systems from primary to tertiary are often unpredictable and chaotic. There is a lack of access to reliable supplies of basic neurology treatments such as antiepileptic drugs. Few countries have nationally accepted guidelines either for the management of epilepsy or status epilepticus. There is a great need to develop better training capacity across Africa in the recognition and management of neurologic conditions in children, from primary health care to the subspecialist level.

    Is bilateral subthalamic nucleus deep brain stimulation (STN DBS) more, less, or as effective as bilateral globus pallidus internus deep brain stimulation (GPi DBS) in treating motor symptoms of Parkinson's disease, as measured by improvements in Unified Parkinson's Disease Rating Scale, part III (UPDRS-III) scores? Given that bilateral STN DBS is at least as effective as bilateral GPi DBS in treating motor symptoms of Parkinson's disease (as measured by improvements in UPDRS-III scores), consideration can be given to the selection of either target in patients undergoing surgery to treat motor symptoms. (Level I). Is bilateral STN DBS more, less, or as effective as bilateral GPi DBS in allowing reduction of dopaminergic medication in Parkinson's disease? When the main goal of surgery is reduction of dopaminergic medications in a patient with Parkinson's disease, then bilateral STN DBS should be performed instead of GPi DBS. (Level I). Is bilateral STN DBS more, less, or as effective as bilateral GPi DBS in treating dyskinesias associated with Parkinson's disease? There is insufficient evidence to make a generalizable recommendation regarding the target selection for reduction of dyskinesias. However, when the reduction of medication is not anticipated and there is a goal to reduce the severity of "on" medication dyskinesias, the GPi should be targeted. (Level I). Is bilateral STN DBS more, less, or as effective as bilateral GPi DBS in improving quality of life measures in Parkinson's disease? When considering improvements in quality of life in a patient undergoing DBS for Parkinson's disease, there is no basis to recommend bilateral DBS in 1 target over the other. (Level I). Is bilateral STN DBS associated with greater, lesser, or a similar impact on neurocognitive function than bilateral GPi DBS in Parkinson disease? If there is significant concern about cognitive decline, particularly in regards to processing speed and working memory in a patient undergoing DBS

We cover Freudian psychoanalysis and later object relations and attachment theories, social theories, illness behavior, classic and operant conditioning, social learning theory, self-regulation theory, cognitive-behavioral theories, and mindfulness. Dissociation and modern cognitive neuroscience theories are covered in other chapters in this series and, although of central importance, are omitted from this chapter.

  6. Causal role for inverse reasoning on obsessive-compulsive symptoms: Preliminary evidence from a cognitive bias modification for interpretation bias study.

    Wong, Shiu F; Grisham, Jessica R

    2017-12-01

    The inference-based approach (IBA) is a cognitive account of the genesis and maintenance of obsessive-compulsive disorder (OCD). According to the IBA, individuals with OCD are prone to using inverse reasoning, in which hypothetical causes form the basis of conclusions about reality. Several studies have provided preliminary support for an association between features of the IBA and OCD symptoms. However, there are currently no studies that have investigated the proposed causal relationship of inverse reasoning in OCD. In a non-clinical sample (N = 187), we used an interpretive cognitive bias procedure to train a bias towards using inverse reasoning (n = 64), healthy sensory-based reasoning (n = 65), or a control condition (n = 58). Participants were randomly allocated to these training conditions. This manipulation allowed us to assess whether, consistent with the IBA, inverse reasoning training increased compulsive-like behaviours and self-reported OCD symptoms. Results indicated that compared to a control condition, participants trained in inverse reasoning reported more OCD symptoms and were more avoidant of potentially contaminated objects. Moreover, change in inverse reasoning bias was a small but significant mediator of the relationship between training condition and behavioural avoidance. Conversely, training in a healthy (non-inverse) reasoning style did not have any effect on symptoms or behaviour relative to the control condition. As this study was conducted in a non-clinical sample, we were unable to generalise our findings to a clinical population. Findings generally support the IBA model by providing preliminary evidence of a causal role for inverse reasoning in OCD. Copyright © 2017 Elsevier Ltd. All rights reserved.

    Full Text Available Perioperative care of the patients with neurological diseases can be challenging. Most important consideration is the management and understanding of pathophysiology of these disorders and evaluation of new neurological changes that occur perioperatively. Perioperative generally refers to 3 phases of surgery: preoperative, intraoperative, and postoperative. We have tried to address few commonly encountered neurological conditions in clinical practice, such as delirium, stroke, epilepsy, myasthenia gravis, and Parkinson disease. In this article, we emphasize on early diagnosis and management strategies of neurological disorders in the perioperative period to minimize morbidity and mortality of patients.

    Physical fitness is a necessity for those living with a spinal cord injury, yet access to fitness facilities, equipment, and specially trained fitness experts are limited. This article introduces the concept of a network of fitness facilities specially geared towards individuals with spinal cord injury and other neurological disorders. The Community Fitness and Wellness branch of the NeuroRecovery Network was created to provide a continuum of care after traditional rehabilitation for individuals living with a spinal cord injury and other neurological disorders. Community Fitness and Wellness facilities translate activity-based interventions performed during rehabilitation into a community setting as well as provide other fitness and wellness opportunities. Community Fitness and Wellness facilities are staffed by professionals with training on the specialized needs of individuals living with spinal cord injury or other neurological disorders. Standardized assessments evaluate functional, health, and quality of life gains at regular intervals.

    Zika virus (ZIKV) disease is a vector-borne infectious disease transmitted by Aedes mosquitoes. Recently, ZIKV has caused outbreaks in most American countries. Areas covered: Publications about neurological complications of ZIKV infection retrieved from pubmed searchers were reviewed, and reference lists and relevant articles from review articles were also examined. Vertical/intrauterine transmission leads to congenital infection and causes microcephaly and congenital ZIKV syndrome. ZIKV preferentially infects human neural progenitor cells and triggers cell apoptosis. ZIKV RNA has been identified in foetal brain tissue and brains of microcephalic infants who died; amniotic fluid and placentas of pregnant mothers; and umbilical cord, cerebro-spinal fluid and meninges of newborns. The increase in the number of Guillain-Barre syndrome (GBS) cases during the ZIKV outbreak in the Americas provides epidemiological evidence for the link between ZIKV infection and GBS. Less frequently reported ZIKV neurological complications include encephalitis/meningoencephalitis, acute disseminated encephalomyelitis, myelitis, cerebrovascular complications (ischemic infarction; vasculopathy), seizures and encephalopathy, sensory polyneuropathy and sensory neuronopathy. Analysis of GBS incidence could serve as an epidemiological 'marker' or sentinel for ZIKV disease and other neurological complications associated to ZIKV. Expert commentary: An expanding spectrum of neurological complications associated with ZIKV infection is being recognised.

    Understanding brain pathology along with the underlying neuroanatomy and the resulting neurological deficits is of vital importance in medical education and clinical practice. To facilitate and expedite this understanding, we created a three-dimensional (3D) interactive atlas of neurological disorders providing the correspondence between a brain lesion and the resulting disorder(s). The atlas contains a 3D highly parcellated atlas of normal neuroanatomy along with a brain pathology database. Normal neuroanatomy is divided into about 2,300 components, including the cerebrum, cerebellum, brainstem, spinal cord, arteries, veins, dural sinuses, tracts, cranial nerves (CN), white matter, deep gray nuclei, ventricles, visual system, muscles, glands and cervical vertebrae (C1-C5). The brain pathology database contains 144 focal and distributed synthesized lesions (70 vascular, 36 CN-related, and 38 regional anatomy-related), each lesion labeled with the resulting disorder and associated signs, symptoms, and/or syndromes compiled from materials reported in the literature. The initial view of each lesion was preset in terms of its location and size, surrounding surface and sectional (magnetic resonance) neuroanatomy, and labeling of lesion and neuroanatomy. In addition, a glossary of neurological disorders was compiled and for each disorder materials from textbooks were included to provide neurological description. This atlas of neurological disorders is potentially useful to a wide variety of users ranging from medical students, residents and nurses to general practitioners, neuroanatomists, neuroradiologists and neurologists, as it contains both normal (surface and sectional) brain anatomy and pathology correlated with neurological disorders presented in a visual and interactive way.

    Fascioliasis is a food-borne parasitic disease caused by the trematode species Fasciola hepatica, distributed worldwide, and Fasciola gigantica, restricted to given regions of Africa and Asia. This disease in humans shows an increasing importance, which relies on its recent widespread emergence related to climate and global changes and also on its pathogenicity in the invasive, biliary, and advanced chronic phases in the human endemic areas, mainly of developing countries. In spite of the large neurological affection capacity of Fasciola, this important pathogenic aspect of the disease has been pronouncedly overlooked in the past decades and has not even appear within the numerous reviews on the parasitic diseases of the central nervous system. The aim of this wide retrospective review is an in-depth analysis of the characteristics of neurological and ocular fascioliasis caused by these two fasciolid species. The terms of neurofascioliasis and ophthalmofascioliasis are restricted to cases in which the direct affection of the central nervous system or the eye by a migrant ectopic fasciolid fluke is demonstrated by an aetiological diagnosis of recovered flukes after surgery or spontaneous moving-out of the fluke through the orbit. Cases in which the ectopic fluke is not recovered and the symptoms cannot be explained by an indirect affection at distance may also be included in these terms. Neurofascioliasis and ophthalmofascioliasis cases are reviewed and discussed. With regard to fascioliasis infection giving an indirect rise to neurological affection, the distribution and frequency of cases are analysed according to geography, sex, and age. Minor symptoms and major manifestations are discussed. Three main types of cases are distinguished depending on the characteristics of their manifestations: genuine neurological, meningeal, and psychiatric or neuropsychic. The impressive symptoms and signs appearing in each type of these cases are included. Brain examination

    To discuss the neurological basis of facial recognition, we present our case reports of impaired recognition and a review of previous literature. First, we present a case of infarction and discuss prosopagnosia, which has had a large impact on face recognition research. From a study of patient symptoms, we assume that prosopagnosia may be caused by unilateral right occipitotemporal lesion and right cerebral dominance of facial recognition. Further, circumscribed lesion and degenerative disease may also cause progressive prosopagnosia. Apperceptive prosopagnosia is observed in patients with posterior cortical atrophy (PCA), pathologically considered as Alzheimer's disease, and associative prosopagnosia in frontotemporal lobar degeneration (FTLD). Second, we discuss face recognition as part of communication. Patients with Parkinson disease show social cognitive impairments, such as difficulty in facial expression recognition and deficits in theory of mind as detected by the reading the mind in the eyes test. Pathological and functional imaging studies indicate that social cognitive impairment in Parkinson disease is possibly related to damages in the amygdalae and surrounding limbic system. The social cognitive deficits can be observed in the early stages of Parkinson disease, and even in the prodromal stage, for example, patients with rapid eye movement (REM) sleep behavior disorder (RBD) show impairment in facial expression recognition. Further, patients with myotonic dystrophy type 1 (DM 1), which is a multisystem disease that mainly affects the muscles, show social cognitive impairment similar to that of Parkinson disease. Our previous study showed that facial expression recognition impairment of DM 1 patients is associated with lesion in the amygdalae and insulae. Our study results indicate that behaviors and personality traits in DM 1 patients, which are revealed by social cognitive impairment, are attributable to dysfunction of the limbic system.

    The aim of this study was to assess the incidence, clinical presentation, and outcomes of neurologic disorders secondary to vitamin B deficiencies following bariatric surgery. Patients at a single academic institution who underwent bariatric surgery and developed neurologic complications secondary to low levels of vitamins B1, B2, B6, and B12 between the years 2004 and 2015 were studied. In total, 47 (0.7%) bariatric surgical patients (Roux-en-Y gastric bypass n = 36, sleeve gastrectomy n = 9, and duodenal switch n = 2) developed neurologic manifestations secondary to vitamin B deficiencies. Eleven (23%) patients developed postoperative anatomical complications contributed to poor oral intake. Median duration to onset of neurologic manifestation following surgery was 12 months (IQR, 5-32). Vitamin deficiencies reported in the cohort included B1 (n = 30), B2 (n = 1), B6 (n = 12), and B12 (n = 12) deficiency. The most common manifestations were paresthesia (n = 31), muscle weakness (n = 15), abnormal gait (n = 11), and polyneuropathy (n = 7). Four patients were diagnosed with Wernicke-Korsakoff syndrome (WKS) which was developed after gastric bypass (n = 3) and sleeve gastrectomy (n = 1). Seven patients required readmission for management of severe vitamin B deficiencies. Overall, resolution of neurologic symptoms with nutritional interventions and pharmacotherapy was noted in 40 patients (85%). The WKS was not reversible, and all four patients had residual mild ataxia and nystagmus at the last follow-up time. Nutritional neurologic disorders secondary to vitamin B deficiency are relatively uncommon after bariatric surgery. While neurologic disorders are reversible in most patients (85%) with vitamin replacements, persistent residual neurologic symptoms are common in patients with WKS.

    The Youth Anxiety Measure for DSM-5 (YAM-5) is a new self- and parent-report questionnaire to assess anxiety disorder symptoms in children and adolescents in terms of the contemporary classification system. International panels of childhood anxiety researchers and clinicians were used to construct a scale consisting of two parts: part one consists of 28 items and measures the major anxiety disorders including separation anxiety disorder, selective mutism, social anxiety disorder, panic disorder, and generalized anxiety disorder, whereas part two contains 22 items that focus on specific phobias and (given its overlap with situational phobias) agoraphobia. In general, the face validity of the new scale was good; most of its items were successfully linked to the intended anxiety disorders. Notable exceptions were the selective mutism items, which were frequently considered as symptoms of social anxiety disorder, and some specific phobia items especially of the natural environment, situational and other type, that were regularly assigned to an incorrect category. A preliminary investigation of the YAM-5 in non-clinical (N = 132) and clinically referred (N = 64) children and adolescents indicated that the measure was easy to complete by youngsters. In addition, support was found for the psychometric qualities of the measure: that is, the internal consistency was good for both parts, as well as for most of the subscales, the parent-child agreement appeared satisfactory, and there was also evidence for the validity of the scale. The YAM-5 holds promise as a tool for assessing anxiety disorder symptoms in children and adolescents.

    To evaluate how well the medications currently approved in the United States for allergic rhinitis (AR) treat nasal symptoms when examined according to Food and Drug Administration-indicated uses and dosages. MEDLINE (1966 onward), EMBASE (1974 onward), and the Cochrane Library (2007) were systematically searched according to the following criteria defined at a roundtable meeting of the authors: randomized controlled trial, at least a 2-week duration, and approved indication and dosage in the United States. Data from studies that met the inclusion criteria were extracted into evidence tables, which were reviewed twice by the full panel of authors. Individual panel members also were asked to comment on abstracts, articles, and summary tables based on their known expertise. The entire faculty approved the selection of studies included in this review. Fifty-four randomized, placebo-controlled studies involving more than 14,000 adults and 1,580 children with AR met the criteria for review: 38 studies of seasonal allergic rhinitis (SAR; n = 11,980 adults and 946 children) and 12 studies of perennial allergic rhinitis (PAR; n = 3,800 adults and 366 children). The median percentage changes from baseline for total nasal symptom score for SAR were as follows: nasal antihistamines, -22.2%; oral antihistamines, -23.5%; intranasal steroids (INSs), -40.7%; and placebo, -15.0%. For PAR, the changes were as follows: oral antihistamines, -51.4%; INSs, -37.3%; and placebo, -24.8%. Data for mediator antagonists were limited. The data, although limited, confirm that INSs produce the greatest improvements in nasal symptoms in patients with SAR. In addition, INSs are effective for PAR, but the data were of variable quality, and oral antihistamines may be equally effective for some patients. The reporting of published data should be standardized to permit better comparisons in future studies.

    Full Text Available Diseases of the tonsils are becoming more resistant to antibiotics due to the persistence of bacteria through the formation of biofilms. Therefore, understanding the microbiology and pathophysiology of such diseases represent an important step in the management of biofilm-related infections. We have isolated the microorganisms, evaluated their antimicrobial susceptibility, and detected the presence of bacterial biofilms in tonsillar specimens in correlation with the clinical manifestations of tonsillar diseases. Therefore, a total of 140 palatine tonsils were collected from 70 patients undergoing tonsillectomy at University Malaya Medical Centre. The most recovered isolate was Staphylococcus aureus (39.65% followed by Haemophilus influenzae (18.53%. There was high susceptibility against all selected antibiotics except for cotrimoxazole. Bacterial biofilms were detected in 60% of patients and a significant percentage of patients demonstrated infection manifestation rather than obstruction. In addition, an association between clinical symptoms like snore, apnea, nasal obstruction, and tonsillar hypertrophy was found to be related to the microbiology of tonsils particularly to the presence of biofilms. In conclusion, evidence of biofilms in tonsils in correlation with the demonstrated clinical symptoms explains the recalcitrant nature of tonsillar diseases and highlights the importance of biofilm’s early detection and prevention towards better therapeutic management of biofilm-related infections.

    To determine the role of brain CT in neurologically asymptomatic lung cancer patients a review was made of the CT and clinical findings in 279 patients. Brain metastases were found in 94.5% of patients with specific abnormal neurological findings, 26.6% of patients with vague neurological signs and symptoms, 11% of patients with oat cell carcinoma and a normal neurological examination, and 40% of patients with adenocarcinoma and a normal neurological examination. Brain metastasis was not seen on CT in the 29 patients with squamous cell carcinoma and a normal neurological examination. It is concluded that brain CT is useful for the detection of occult brain metastases, particularly oat cell carcinoma and adenocarcinoma, in neurologically asymptomatic lung cancer patients

    Osteopathic medical schools have a longstanding tradition of training primary care physicians (PCP). Neurologic symptoms are common in the PCP's office and there is an undersupply of neurologists in the United States. It is therefore crucial for osteopathic medical students to have a strong foundation in clinical neurology. Despite the importance, a mere 6% of osteopathic medical schools have required neurology clerkships. Furthermore, exposure to neurology in medical school through required clerkships has been correlated with matching into neurology residency. As osteopathic medical schools continue to expand, it will become increasingly important to emphasize the American Academy Neurology's published guidelines for a core clerkship curriculum. Practicing neurologists should take an active role in encouraging osteopathic medical schools to adopt these guidelines. © 2017 American Academy of Neurology.

    In the last several years, traditional Chinese medicine (TCM) has made much progress in the treatment of neurological diseases. The living space of TCM in neurological diseases lies in refractory diseases, aging and chronic diseases caused by multiple factors as well as sub-health state and chronic fatigue state. The effect model of TCM mainly consists of whole effect, self-organization,self-stable model, holographic effect and butterfly effect. The effective point of TCM in neurological diseases lies mainly in end-points and health-related events. Moreover, TCM has advantages in the evaluation of symptoms, syndrome and quality of life (QOL). Some key indexes should be included when evaluating the efficacy of TCM in neurological diseases. Meanwhile, the advantages of TCM such as end-points, health-related events and QOL should be highlighted. Multi-subject researching methods could be adopted to make a comprehensive evaluation of subjective and objective indexes.The clinical evidence on the TCM efficacy evaluation may come from RCTs, and other types of designs can also be considered.

  4. Neurological examination in small animals

    Full Text Available This clinical review about the neurological examination in small animals describes the basics about the first steps of investigation when dealing with neurological patients. The knowledge of how to perform the neurological examination is important however more important is how to correctly interpret these performed tests. A step-by-step approach is mandatory and examiners should master the order and the style of performing these tests. Neurological conditions can be sometimes very distressing for owners and for pets that might not be the most cooperating. The role of a veterinary surgeon, as a professional, is therefore to collect the most relevant history, to examine a patient in a professional manner and to give to owners an educated opinion about the further treatment and prognosis. However neurological examinations might look challenging for many. But it is only the clinical application of neuroanatomy and neurophysiology to an every-day situation for practicing veterinarians and it does not require any specific in-to-depth knowledge. This clinical review is aimed not only to provide the information on how to perform the neurological examination but it is also aimed to appeal on veterinarians to challenge their daily routine and to start practicing on neurologically normal patients. This is the best and only way to differentiate between the normal and abnormal in a real situation.

    The Netherlands Society of Neurology evolved from the Society of Psychiatry founded in 1871. The name was changed into Netherlands Society of Psychiatry and Neurology (NSPN) in 1897. In the same year, the word neurology was also added to the name of the journal. The Society steadily blossomed, but in 1909 the first signs of dissatisfaction occurred: the Amsterdam Neurologists Society was founded. A few split-offs would follow. The number of members of the NSPN increased from 205 in 1920 to 585 in 1960. In the early 1960s, the Society was reorganised and would consist of two sections, one for psychiatry and one for neurology. However, this would not last, as a full separation was established in 1974. For several reasons, the name of the journal was changed four times until it assumed its present name in 1974. The 100th volume of CNN was not published, as expected. in 1996, but in 1998, because of two skipped publication years, one during WWII and another in the 1970s. During the last decades of the nineteenth century, teaching of neurology was mostly given within the frame of psychiatry, following the German tradition of 'brainpsychiatry' (organic or biologic psychiatry). The first official chair of psychiatry was founded at Utrecht, 1893 (Winkler). In Amsterdam, private teachers such as Delprat taught 'electro-therapy and nervous diseases' since the 1880s. The first extraordinary chair of neurology and electrotherapy was founded for his successor, Wertheim Salomonson in 1899. The first university clinic for psychiatry and neurology started at the Amsterdam Municipal University, when Winkler became professor of psychiatry and neurology in Amsterdam in 1896. Around the turn of the century, chairs of psychiatry and neurology were also founded in Groningen and Leiden. Separate chairs for neurology and psychiatry appeared in Amsterdam in 1923 and in Utrecht in 1936. Following an initiative of Brouwer, the first neurological university clinic opened its doors in

    Quality of neurologic emergency management in an under-resourced country may be improved by standard operating procedures (SOPs). Neurologic SOPs were implemented in a large urban (Banjul) and a small rural (Brikama) hospital in the Gambia. As quality indicators of neurologic emergency management, performance of key procedures was assessed at baseline and in the first and second implementation years. At Banjul, 100 patients of the first-year intervention group exhibited higher rates of general procedures of emergency management than 105 control patients, such as neurologic examination (99.0% vs 91.4%; p process quality of neurologic emergency management in under-resourced settings. This study provides Class IV evidence that, for patients with suspected neurologic emergencies in sub-Saharan Africa, neurologic SOPs increase the rate of performance of guideline-recommended procedures.

    To evaluate the factors which influence the decision to pursue a career in neurology. An anonymous survey was developed using a Likert scale to rate responses. The survey was sent to adult and child neurology faculty, residents and fellows, as well as medical students applying for neurology. Descriptive statistics were used to analyse the factors of influence. Respondents were subsequently categorized into pre-neurology trainees, neurology trainees, child neurologists and adult neurologists, and differences between the groups were analysed using Pearson's chi-square test. One hundred and thirty-three anonymous responses were received. The respondents were neurologists across all levels of training and practice. Across all respondents, the most common factor of high importance was intellectual content of specialty, challenging diagnostic problems, type of patient encountered and interest in helping people. Responses were similar across the groups; however, the earliest trainees cited interest in helping people as most important, while those in neurology training and beyond cite intellectual content of the specialty as most important. As trainees transition from their earliest levels of clinical experience into working as residents and faculty, there is a shift in the cited important factors. Lifestyle and financial factors seem to be the least motivating across all groups. Encouragement from peers, mentors, faculty and practicing physicians is considered high influences in a smaller number of neurologists. This may present an opportunity for practicing neurologists to make connections with medical students early in their education in an effort to encourage and mentor candidates.

    Much is known regarding the physical characteristics, comorbid symptoms, psychological makeup, and neuropsychological performance of patients with functional neurological disorders (FNDs)/conversion disorders. Gross neurostructural deficits do not account for the patients' deficits or symptoms. This review describes the literature focusing on potential neurobiological (i.e. functional neuroanatomic/neurophysiological) findings among individuals with FND, examining neuroimaging and neurophysiological studies of patients with the various forms of motor and sensory FND. In summary, neural networks and neurophysiologic mechanisms may mediate "functional" symptoms, reflecting neurobiological and intrapsychic processes.

    Enterovirus 71 frequently involves the central nervous system and may present with a variety of neurologic manifestations. Here, we aimed to describe the clinical features, magnetic resonance imaging (MRI) findings, and cerebrospinal fluid (CSF) profiles of patients presenting with neurologic complications of enterovirus 71 infection. We retrospectively reviewed the records of 31 pediatric patients hospitalized with acute neurologic manifestations accompanied by confirmed enterovirus 71 infection at Ulsan University Hospital between 2010 and 2014. The patients' mean age was 2.9 ± 5.5 years (range, 18 days to 12 years), and 80.6% of patients were less than 4 years old. Based on their clinical features, the patients were classified into 4 clinical groups: brainstem encephalitis (n = 21), meningitis (n = 7), encephalitis (n = 2), and acute flaccid paralysis (n = 1). The common neurologic symptoms included myoclonus (58.1%), lethargy (54.8%), irritability (54.8%), vomiting (48.4%), ataxia (38.7%), and tremor (35.5%). Twenty-five patients underwent an MRI scan; of these, 14 (56.0%) revealed the characteristic increased T2 signal intensity in the posterior region of the brainstem and bilateral cerebellar dentate nuclei. Twenty-six of 30 patients (86.7%) showed CSF pleocytosis. Thirty patients (96.8%) recovered completely without any neurologic deficits; one patient (3.2%) died due to pulmonary hemorrhage and shock. In the present study, brainstem encephalitis was the most common neurologic manifestation of enterovirus 71 infection. The characteristic clinical symptoms such as myoclonus, ataxia, and tremor in conjunction with CSF pleocytosis and brainstem lesions on MR images are pathognomonic for diagnosis of neurologic involvement by enterovirus 71 infection.

    Human Immunodeficiency Virus (HIV) is neurotropic and immunotropic, making themassive destruction of both systems. Although their amount has been reduced, there is still neurological presentations and complications of HIV remain common in the era of combination antiretroviral therapy (cART). Neurological opportunistic infections (OI) occur in advanced HIV diseases such as primary cerebral lymphoma, cryptococcal meningitis, cerebral toxoplasmosis, and progressive multifocal encephalopathy. Neurological problem directly related to HIV appear at any stage in the progress of HIV disease, from AIDS-associated dementia to the aseptic meningitis of primary HIV infection observed in subjects with an immune deficiency. The replication of peripheral HIV viral is able to be controlled in the era of effective antiretroviral therapy. Non-HIV-related neurological disease such as stroke increased important as the HIV population ages.

    Sufferers from neurologic and psychiatric disorders are not uncommonly defendants in criminal trials. This chapter surveys a variety of different ways in which neurologic disorder bears on criminal responsibility. It discusses the way in which a neurologic disorder might bear on the questions of whether or not the defendant acted voluntarily; whether or not he or she was in the mental state that is required for guilt for the crime; and whether or not he or she is deserving of an insanity defense. The discussion demonstrates that a just determination of whether a sufferer from a neurologic disorder is diminished in his or her criminal responsibility for harmful conduct requires equal appreciation of the nature of the relevant disorder and its impact on behavior, on the one hand, and of the legal import of facts about the psychologic mechanisms through which behavior is generated, on the other. © 2013 Elsevier B.V.

    To chronicle the history of medicine and neurology in India with a focus on its establishment and evolution. THE HISTORY OF NEUROLOGY IN INDIA IS DIVIDED INTO TWO PERIODS: ancient and modern. The ancient period dates back to the mid-second millennium Before Christ (B.C.) during the creation of the Ayurvedic Indian system of Medicine, which detailed descriptions of neurological disorders called Vata Vyadhi. The early 20(th) century witnessed the birth of modern Indian medicine with the onset of formal physician training at the nation's first allopathic medical colleges located in Madras (1835), Calcutta (1835) and Mumbai (1848). Prior to India's independence from Britain in 1947, only 25 medical schools existed in the entire country. Today, there are over 355. In 1951, physicians across the field of neurology and neurosurgery united to create the Neurological Society of India (NSI). Four decades later in 1991, neurologists branched out to establish a separate organization called the Indian Academy of Neurology (IAN). Information was gathered through literature review using PubMed, MD Consult, OVID, primary texts and research at various academic institutions in India. Neurological disorders were first described in ancient India under Ayurveda. The transition to modern medicine occurred more recently through formal training at medical schools beginning in the 1930's. Early pioneers and founders of the NSI (1951) include Dr. Jacob Chandy, Dr. B Ramamurthi, Dr. S. T. Narasimhan and Dr. Baldev Singh. Later, Dr. J. S. Chopra, a prominent neurologist and visionary, recognized the need for primary centers of collaboration and subsequently established the IAN (1991). The future of Neurology in India is growing rapidly. Currently, there are 1100 practicing neurologists and more than 150 post-graduate trainees who join the ranks every year. As the number of neurologists rises across India, there is an increase in the amount of basic, clinical and epidemiological research being

    Purpose. To determine the incidence of neurologic complications of cerebral angiography in children with moyamoya syndrome (MMS) as compared to children without MMS. Materials and methods. One-hundred-ninety consecutive cerebral angiograms obtained in 152 children were evaluated. Sixty of these angiograms were obtained in 40 children with MMS. Patients underwent neurologic evaluation prior to and after the procedure. For this study, a neurologic complication was defined as any new focal neurologic deficit or alteration in mental status occurring during the procedure or within the ensuing 24 hours. Results. There were 2 neurologic complications within 24 hours of angiography, one in the MMS group and one in the non-MMS group. One patient with MMS became mute following angiography. The symptom resolved within 12 hours. One patient without MMS being examined postoperatively for residual arteriovenous malformation developed intracranial hemorrhage requiring reexploration 12 hours after the angiogram. Using a two-tail Fisher`s exact test, there was no significant statistical difference in the ischemic (P = 0.3) or hemorrhagic (P = 1.0) complication rates between the group of patients with MMS and the non-MMS groups. Conclusion. The risk of a neurologic complication from cerebral angiography in children with MMS is low and not statistically different from the risk in children with other cerebrovascular disorders.

    In 2006, the number of pediatric outpatients consulting our hospital during non-practice hours increased by 218.1% of that in 1996. The number of pediatric inpatients during non-practice hours in 2006 increased by 71.3% of that in 1996. In 2006, the number of patients who were admitted with neurological disorders in children during non-practice hours increased to 213.3% of that in 1996. The proportion of these pediatric patients among those who were admitted during non-practice hours was 16.6% in our hospital, suggesting the importance of neurological disorders in pediatric emergency medicine. More than 60% of inpatients with neurological disorders in children were 3 years old or younger. The most common neurological symptoms observed at admission included convulsion (81.6%) and disturbance of consciousness (8.5%). The disorders were mainly febrile seizure (41.4%) and epilepsy (29.0%). Most patients with severe disorders requiring emergency medicine, such as head bruise, acute encephalitis/encephalopathy, purulent meningitis, and head trauma, were admitted during non-practice hours. The prognoses of most neurological disorders in children were favorable. However, patients with sequelae (especially, hypoxic encephalopathy, acute encephalitis/encephalopathy) showed an unfavorable neurological prognosis. Early rehabilitation during admission was useful as a support method for their families. In the future, a comprehensive rehabilitation program for children with acquired brain injury should be established and laws to promote home care must be passed.

  4. Who Can Diagnose Parkinson's Disease First? Role of Pre-motor Symptoms.

    In 1817, James Parkinson described the disease which bears his name. The disease was defined as a neurological syndrome characterized by tremor, rigidity, and slowness of movements. Almost one hundred years later, degeneration of neurons in the substantia nigra and low levels of dopamine were identified as the putative cause of the disease, thus the disease remained as a pure neurological disorder. In the late 1990s, non-motor symptoms of the disease began to gain interest because of their clinical relevance, as well as for their potential role in broadening the understanding of the pathophysiological mechanisms involved. In the last decade, focus has shifted to the pre-motor symptoms, those non-motor symptoms that present years before the motor onset of the disease. The main premotor symptoms include rapid eye movement sleep behavior disorder, hyposmia, constipation and depression. Subjects with these symptoms usually are not initially seen by a neurologist, and by the time they are consulted neuronal loss in the substantia nigra is over 50%. This review summarizes the overall relevance of non-motor symptoms, their frequency and their pathophysiological implications. Also, the importance of pre-motor symptoms, and the role of specialists other than neurologists in diagnosing subjects with Parkinson's disease is discussed. Two hundred years after the first description of the disease, it is now evident that Parkinson's disease is a systemic disease and a multispecialty team approach is mandatory. Copyright © 2017 IMSS.

    Hippocrates is one of the most influential medical doctors of all times. He started observing and experimenting in times of mysticism and magic. He carried a holistic and humanitarian approach to the patient with examination as the principal approach-inspection, palpation and auscultation are still the most important tools in diagnosing algorithms of today. He had immense experience with the human body most likely due to numerous wound treatments he had performed; some even believe he performed autopsies despite the negative trend at the time. Hippocrates identified the brain as the analyst of the outside world, the interpreter of consciousness and the center of intelligence and willpower. Interestingly, Hippocrates was aware of many valid concepts in neurology; his treatise On the Sacred Disease was the most important for understanding neurology and epilepsy. His other ideas pioneered modern day neurology mentioning neurological diseases like apoplexy, spondylitis, hemiplegia, and paraplegia. Today, 10 % of neurological Pubmed and 7 % of neuroscience Scopus reviews mention Corpus Hippocraticum as one of the sources. Therefore, Hippocrates may be considered as the forefather of neurology.

  6. Electrophysiological evidence of the time course of attentional bias in nonpatients reporting symptoms of depression with and without co-occurring anxiety

    Full Text Available Anxiety is characterized by attentional biases to threat, but findings are inconsistent for depression. To address this inconsistency, the present study systematically assessed the role of co-occurring anxiety in attentional bias in depression. In addition, the role of emotional valence, arousal, and gender was explored. Ninety-two nonpatients completed the Penn State Worry Questionnaire (PSWQ; Meyer et al., 1990; Molina & Borkovec, 1994 and portions of the Mood and Anxiety Symptom Questionnaire (MASQ; Watson, Clark, et al., 1995; Watson, Weber, et al., 1995. Individuals reporting high levels of depression and low levels of anxiety (depression only, high levels of depression and anxiety (combined, or low levels of both (control completed an emotion-word Stroop task during event-related brain potential (ERP recording. Pleasant and unpleasant words were matched on emotional arousal level. An attentional bias was not evident in the depression-only group. Women in the combined group had larger N200 amplitude for pleasant than unpleasant stimuli, and the combined group as a whole had larger right-lateralized P300 amplitude for pleasant than unpleasant stimuli, consistent with an early and later attentional bias that is specific to unpleasant valence in the combined group. Men in the control group had larger N200 amplitude for pleasant than unpleasant stimuli, consistent with an early attentional bias that is specific to pleasant valence. The present study indicates that the nature and time course of attention prompted by emotional valence and not arousal differentiates depression with and without anxiety, with some evidence of gender moderating early effects. Overall, results suggest that co-occurring anxiety is more important than previously acknowledged in demonstrating evidence of attentional biases in depression.

  7. Comparison of neurological health outcomes between two adolescent cohorts exposed to pesticides in Egypt.

    Full Text Available Pesticide-exposed adolescents may have a higher risk of neurotoxic effects because of their developing brains and bodies. However, only a limited number of studies have addressed this risk among adolescents. The aim of this study was to compare neurological outcomes from two cohorts of Egyptian adolescents working as pesticide applicators. In 2005 and 2009, two cohorts of male adolescents working as pesticide applicators for the cotton crop were recruited from Menoufia Governorate, Egypt. The same application schedule and pesticides were used at both times, including both organophosphorus, and pyrethroid compounds. Participants in both cohorts completed three neurobehavioral tests, health and exposure questionnaires, and medical and neurological screening examinations. In addition, blood samples were collected to measure butyryl cholinesterase (BChE activity. Pesticide applicators in both cohorts reported more neurological symptoms and signs than non-applicators, particularly among participants in the 2005 cohort (OR ranged from 1.18 to 15.3. Except for one test (Trail Making B, there were no significant differences between either applicators or non-applicators of both cohorts on the neurobehavioral outcome measures (p > 0.05. The 2005 cohort showed greater inhibition of serum BChE activity than the 2009 cohort (p < 0.05. In addition, participants with depressed BChE activity showed more symptoms and signs than others without BChE depression (p < 0.05. Our study is the first to examine the consistency of health outcomes associated with pesticide exposure across two cohorts tested at different times from the same geographical region in rural Egypt. This similar pattern of findings across the two cohorts provides strong evidence of the health impact of exposure of adolescents to pesticides.

  8. Unstable mutations: cause of some neurological hereditary diseases

    Unstable mutations or amplification of triplets constitute a kind of genetic alteration discovered during the last decade. They had been found inside or near genes important for the normal neurological function of the human being. In some cases, the presence of the amplification causes the inactivation of the gene or the synthesis of a new product which functions different from the original protein. Some common characteristics of diseases caused by the amplification of triplets are that it affects the nervous system and are degenerative in nature. The expression of the manifestations varies according to age. Most of them show genetic anticipation in which the severity of the manifestations increases with each generation and appear at an earlier age. In most cases, the severity of the symptoms is correlated positively to the size of the amplification. The diagnosis of an affected individual in a family may indicate the presence of an altered gene in other relatives. These relatives may not present evident signs of the illness either because it is of late onset or because they carry premutations. The molecular diagnosis of these mutations is important to estimate the risk of developing the disease and/or of transmitting the illness to the descendants and to eliminate the fears of healthy relatives who have inherited normal copies of the gene.

    We divided 38 patients with cerebrovascular disease of the thalamus into 5 groups according to the site of the thalamic lesions as confirmed by X-ray CT and/or MRI. In 16 patients, we examined the cerebral blood flow (CBF) and cerebral metabolic rate of oxygen (CMRO{sub 2}) by positron emission tomography (PET). In the anteromedial thalamic lesion group, patients displayed disturbances of spontaneity, memory, reading and writing. CBF and CMRO{sub 2} were decreased in the frontal, parietal and temporal lobes on the side of the lesion. In the dorsolateral thalamic lesion group, ataxic hemiparesis was a characteristic symptom. CBF and CMRO{sub 2} were decreased in frontoparietal lobes on the side of the lesion. In the group with lesions confined to the nucleus ventralis posterioris thalami, the main symptoms were sensory disturbance, with cheiro-oral sensory syndrome being particularly evident. CBF and CMRO{sub 2} were decreased in the parietal lobe on the side of the lesion. In the group with posterolateral thalamic lesions without pulvinar involvement, patients exhibited thalamic syndrome without thalamic pain. CBF and CMRO{sub 2} were decreased in the frontoparietal and temporal lobes on the side of the lesion. In contrast, in the group with posterolateral thalamic lesions with pulvinar involvement, all patients showed thalamic pain. The decrease in CBF and CMRO{sub 2} extended to the inferomedial region of the temporal lobe in addition to the area of decreased CBF and CMRO{sub 2} observed in the group with posterolateral thalamic lesions without pulvinar involvement. Based on these results, we speculate that the neurological manifestations of thalamic vascular disease are associated with a decrease in cortical CBF and CMRO{sub 2} secondary to the thalamic lesions.

    We present the results of an 18-month study of a new model of how to care for emergency neurological admissions. We have established a hyperacute neurology team at a single district general hospital. Key features are a senior acute neurology nurse coordinator, an exclusively consultant-delivered service, acute epilepsy nurses, an acute neurophysiology service supported by neuroradiology and acute physicians and based within the acute medical admissions unit. Key improvements are a major increase in the number of patients seen, the speed with which they are seen and the percentage seen on acute medical unit before going to the general wards. We have shown a reduced length of stay and readmission rates for patients with epilepsy. Epilepsy accounted for 30% of all referrals. The cost implications of running this service are modest. We feel that this model is worthy of widespread consideration. © Royal College of Physicians 2017. All rights reserved.

    Full Text Available Scientific bacground: It has been reported that; Multiple Sclerosis (MS may be presented with many psychiatric symptoms such as anxiety, depression, mania and psychosis. MS cases, presented with psychiatric symptoms were also reported. Cases: Two MS cases, diagnosed as psychotic and bipolar disorder respectively, were reported in this paper. Both of the cases were responded to the steroid treatment, and neurological and psychiatric examinations were found to be normal after one month. CONCLUSION: MS cases might be presented with psychiatric complaints and symptoms except neurological ones. We conclude that; psychiatric evaluation as well as the neurological evaluation is important in the MS cases presented with psychiatric symptoms

    Retinitis pigmentosa (RP) refers to a group of inherited retinal diseases with phenotypic and genetic heterogeneity. The pathophysiologic basis of the progressive visual loss in patients with RP is not completely understood but is felt to be due to a primary retinal photoreceptor cell degenerative process mainly affecting the rods of the peripheral retina. In most cases RP is seen in isolation (nonsyndromic), but in some other cases it may be a part of a genetic, metabolic, or neurologic syndrome or disorder. Nyctalopia, or night blindness, is the most common symptom of RP. The classic fundus appearance of RP includes retinal pigment epithelial cell changes resulting in retinal hypo- or hyperpigmentation ("salt-and-pepper"), retinal granularity, and bone spicule formation. The retinal vessels are often narrowed or attenuated and there is a waxy pallor appearance of the optic nerve head. Electroretinography will demonstrate rod and cone photoreceptor cell dysfunction and is a helpful test in the diagnosis and monitoring of patients with RP. A detailed history with pedigree analysis, a complete ocular examination, and the appropriate paraclinical testing should be performed in patients complaining of visual difficulties at night or in dim light. This review discusses the clinical manifestations of RP as well as describing the various systemic diseases, with a special emphasis on neurologic diseases, associated with a pigmentary retinopathy.

    To determine the prevalence, clinical manifestations, and laboratory features of Neuro-Behcets disease. This prospective study was carried out in the Behcets Research Clinic in Shiraz (south-west Iran) and included the patients referred from 1990-1999. The patients' clinical records, images, CSF analyses, and electrodiagnostic studies were reviewed. Eighteen (15 males and 3 females) out of 690 Behcet s patients (2.6%, 95% CI = 1.4-3.8%) were found to have neurological involvement. The mean +/- standard deviation age of these patients was 34.7 +/- 8.6 years. All fulfilled the criteria of the International Study Group of Behcet s Disease. Central nervous system involvement was more common than peripheral nervous system manifestations. Headache, weakness, tingling, and numbness were the most common symptoms. Hyperreflexia, upward plantar reflex, and somatosensory findings were the most frequent signs. Hemispheral and brainstem stroke-like syndromes and cerebral venous thrombosis were the major neurologic presentations. There were also cases of myelitic, pure meningoencephalitic, amyotrophic lateral sclerosis-like, multiple sclerosis-like, and Guillain Barre syndromes. Neuro-Behcets disease must be considered in the differential diagnosis of stroke in young adults, chronic meningitis, intracranial hypertension, multiple sclerosis, myelopathies, and peripheral neuropathies.

    2013-07-01

    Meige's syndrome is a rare neurological syndrome characterized by oromandibular dystonia and blepharospasm. Its pathophysiology is not clearly determined. A 35-year-old female presented to psychiatric department with blepharospasm and oromandibular dystonia with clinical provisional diagnosis of psychiatric disorder (Conversion Disorder). After thorough physical examination including detailed neurological exam and psychiatric evaluation no formal medical or psychiatric diagnosis could be made. The other differential diagnoses of extra pyramidal symptom, tardive dyskinesia, conversion disorder, anxiety disorder were ruled out by formal diagnostic criteria. Consequently with suspicion of Meige's syndrome she was referred to the department of Neurology and the diagnosis was confirmed. Hence, Meige's syndrome could be misdiagnosed as a psychiatric disorder such as conversion disorder or anxiety disorder because clinical features of Meige's syndrome are highly variable and affected by psychological factors and also can be inhibited voluntarily to some extent.

    Beginning in 2014, US neurology residency programs were required to report each trainee's educational progression within 29 neurology Milestone competency domains. Trainee assessment systems will need to be adapted to inform these requirements. The primary aims of this study were to validate neurology resident assessment content using observable practice activities (OPAs) and to develop assessment formats easily translated to the Neurology Milestones. A modified Delphi technique was used to establish consensus perceptions of importance of 73 neurology OPAs among neurology educators and trainees at 3 neurology residency programs. A content validity score (CVS) was derived for each neurology OPA, with scores ≥4.0 determined in advance to indicate sufficient content validity. The mean CVS for all OPAs was 4.4 (range 3.5-5.0). Fifty-seven (78%) OPAs had a CVS ≥4.0, leaving 16 (22%) below the pre-established threshold for content validity. Trainees assigned a higher importance to individual OPAs (mean CVS 4.6) compared to faculty (mean 4.4, p = 0.016), but the effect size was small (η(2) = 0.10). There was no demonstrated effect of length of education experience on perceived importance of neurology OPAs (p = 0.23). Two sample resident assessment formats were developed, one using neurology OPAs alone and another using a combination of neurology OPAs and the Neurology Milestones. This study provides neurology training programs with content validity evidence for items to include in resident assessments, and sample assessment formats that directly translate to the Neurology Milestones. Length of education experience has little effect on perceptions of neurology OPA importance. © 2015 American Academy of Neurology.

    A body of evidence has supported that patients with obsessive-compulsive disorder (OCD) have increased rates of various neurological soft signs (NSS) compared to controls. Various lines of research has documented robust relationships between OCD and dissociative symptomatology. The study aimed to examine the associations between obsessive-compulsive symptoms, dissociative experiences alexithymia, and NSS. The study included thirty OCD patients and thirty healthy controls, matched for age, marital status, education, and income. The Neurological Evaluation Scale (NES), Padua Inventory-Revised (PI-R), Dissociative Experiences Scale (DES) and Toronto Alexithymia Scale (TAS-20) were administered. In comparison to healthy controls, patients with OCD had difficulty sequencing for complex motor acts and greater absorption/ imaginative involvement. Using latent class analysis, the study sample was classified into two homogenous subsets as mild NSS (n = 45) and severe NSS (n = 15). Majority of the participants who were grouped into severe NSS latent class were OCD patient (n = 14, 93.3%). Furthermore, those with severe NSS reported greater levels of alexithymia and more severe obsessive-compulsive symptoms, particularly precision. We concluded that relationships between OCD severity and NSS appear to be of crucial importance. Our data along with accumulated evidence suggest that OCD associated with pronounced NSS may represent a specific subtype of the disorder. Copyright © 2017 Elsevier B.V. All rights reserved.

    Background: Neurologic complications may be the first symptoms of atrial myxomas. Understanding the imaging features of neurologic complications of atrial myxomas can be helpful for the prompt diagnosis. Objective: To identify neuroimaging features for patients with neurologic complications attributed to atrial myxoma. Methods: We retrospectively reviewed the medical records of 103 patients with pathologically confirmed atrial myxoma at Xiangya Hospital from January 2009 to January 2014. The neuroimaging data for patients with neurologic complications were analyzed. Results: Eight patients with atrial myxomas (7.77%) presented with neurologic manifestations, which constituted the initial symptoms for seven patients (87.5%). Neuroimaging showed five cases of cerebral infarctions and three cases of aneurysms. The main patterns of the infarctions were multiplicity (100.0%) and involvement of the middle cerebral artery territory (80.0%). The aneurysms were fusiform in shape, multiple in number (100.0%) and located in the distal middle cerebral artery (100.0%). More specifically, high-density in the vicinity of the aneurysms was observed on CT for two patients (66.7%), and homogenous enhancement surrounding the aneurysms was detected in the enhanced imaging for two patients (66.7%). Conclusion: Neurologic complications secondary to atrial myxoma consist of cerebral infarctions and aneurysms, which show certain characteristic features in neuroimaging. Echocardiography should be performed in patients with multiple cerebral infarctions, and multiple aneurysms, especially when aneurysms are distal in location. More importantly, greater attention should be paid to the imaging changes surrounding the aneurysms when myxomatous aneurysms are suspected and these are going to be the relevant features in our article

    Patients with urea cycle disorders (UCDs) have an increased risk of neurological disease manifestation. Determining the effect of diagnostic and therapeutic interventions on the neurological outcome. Evaluation of baseline, regular follow-up and emergency visits of 456 UCD patients prospectively followed between 2011 and 2015 by the E-IMD patient registry. About two-thirds of UCD patients remained asymptomatic until age 12 days [i.e. the median age at diagnosis of patients identified by newborn screening (NBS)] suggesting a potential benefit of NBS. In fact, NBS lowered the age at diagnosis in patients with late onset of symptoms (>28 days), and a trend towards improved long-term neurological outcome was found for patients with argininosuccinate synthetase and lyase deficiency as well as argininemia identified by NBS. Three to 17 different drug combinations were used for maintenance therapy, but superiority of any single drug or specific drug combination above other combinations was not demonstrated. Importantly, non-interventional variables of disease severity, such as age at disease onset and peak ammonium level of the initial hyperammonemic crisis (cut-off level: 500 μmol/L) best predicted the neurological outcome. Promising results of NBS for late onset UCD patients are reported and should be re-evaluated in a larger and more advanced age group. However, non-interventional variables affect the neurological outcome of UCD patients. Available evidence-based guideline recommendations are currently heterogeneously implemented into practice, leading to a high variability of drug combinations that hamper our understanding of optimised long-term and emergency treatment.

    Full Text Available Paraneoplastic neurologic disorders are extremely rare in cancer patients and are most commonly associated with certain tumors, such as ovarian cancer, small cell lung cancer, and breast cancer. We report here a paraneoplastic neurological syndrome in a 53-year-old man with colonic adenocarcinoma with a solitary liver metastasis. His paraneoplastic syndrome was successfully treated by methylprednisolone and primary oncologic therapies including neoadjuvant chemotherapy and definitive surgery. This is also the first documented case of simultaneous manifestation of a sensory neuropathy and limbic encephalitis with colon cancer.

    Palliative care is an approach to the care of patients and families facing progressive and chronic illnesses that focuses on the relief of suffering due to physical symptoms, psychosocial issues, and spiritual distress. As neurologists care for patients with chronic, progressive, life-limiting, and disabling conditions, it is important that they understand and learn to apply the principles of palliative medicine. In this article, we aim to provide a practical starting point in palliative medicine for neurologists by answering the following questions: (1) What is palliative care and what is hospice care? (2) What are the palliative care needs of neurology patients? (3) Do neurology patients have unique palliative care needs? and (4) How can palliative care be integrated into neurology practice? We cover several fundamental palliative care skills relevant to neurologists, including communication of bad news, symptom assessment and management, advance care planning, caregiver assessment, and appropriate referral to hospice and other palliative care services. We conclude by suggesting areas for future educational efforts and research. © 2014 American Academy of Neurology.

    2017-01-01

    Medical cannabis is increasingly used as a treatment or adjunct treatment with different levels of efficacy in several neurological disorders or related symptoms (such as multiple sclerosis, autism, Parkinson and Alzheimer disease, Tourette's syndrome, Huntington's disease, neuropathic pain, epilepsy, headache), as well as in other medical conditions (e.g. nausea and vomiting, glaucoma, appetite stimulation, cancer, inflammatory conditions, asthma). Nevertheless, a number of neurological adverse effects from use of medical cannabis on the short- and on the longterm have been reported, in addition to other adverse health events. It has been noticed that the use of medical cannabis can lead to a paradoxical effects depending on the amount of delta-9-tetrahydrocannabinol (THC) -like cannabinoids the preparation contain. Accordingly, some neurological disorders or symptoms (e.g. multiple sclerosis, seizures, epilepsy, headache) may be caused or exacerbated by the same treatment supposed to cure them. The current review presents an update of the neurological adverse effects resulting from the use of cannabis for medical purposes, highlighting the need to weigh the benefits and risks, when using cannabinoidbased treatments.

    Diagnosing infective endocarditis and its complications can be difficult because of the nonspecific symptoms. We reviewed findings of intracranial abnormalities on magnetic resonance imaging (MRI) in 14 patients with neurological complications and herein discuss the overall intracranial MRI findings. We retrospectively reviewed patients with infective endocarditis from August 2004 to August 2006. Brain MRI, the causative bacteria, and abnormal neurological symptoms were reviewed for 14 patients with neurological complications. Of the 14 patients, 13 showed intracranial abnormalities on MRI. Embolization was seen in 10 patients, hemorrhage in 3, abscess formation in 3, and encephalitis in 2. Hyperintense lesions with a central hypointense area on T2-weighted and/or T2*-weighted imaging (Bull's-eye-like lesion) were seen in four patients. A combination of these intracranial abnormalities was observed in 6 patients. The MRI findings associated with infective endocarditis are wide-ranging: embolization, hemorrhage, meningitis, cerebritis, abscess, the bull's-eye-like lesion. Clinicians should consider the possibility of infective endocarditis in patients with unknown fever and neurological abnormality. Brain MRI should be promptly performed for those patients, and T2*-weighted imaging is recommended for an early diagnosis of infective endocarditis. (author)

    2015-01-01

    Neurologic injury after regional anesthesia or pain medicine procedures is rare. Postprocedural neurologic deficits may create high levels of anxiety for the patient and practitioner, although most deficits are limited in severity and can be expected to fully resolve with time. Postoperative anesthesia-related neuraxial and peripheral nerve injuries are reviewed to define an efficient, structured approach to these complications. Emphasis is placed on acutely stratifying the urgency and scope of diagnostic testing or consultation necessity, initiating appropriate definitive treatments, and defining appropriate out-of-hospital follow-up and symptom management. Studies pertinent to the recognition, evaluation, and treatment of neurologic assessment of perioperative nerve injury and published since the last advisory on the topic are reviewed and a new structured algorithmic approach is proposed. The evolving literature on postoperative inflammatory neuropathies is reviewed to help define the clinical criteria and to identify patients who would benefit from early neurological evaluation. New sections review potential acute interventions to improve neurologic outcome and long-term management of neuropathic pain resulting from perioperative nerve injury.

    Objective: To assess the strengths and weaknesses of neurology resident education using survey methodology. Methods: A 27-question survey was sent to all neurology residents completing residency training in the United States in 2011. Results: Of eligible respondents, 49.8% of residents returned the survey. Most residents believed previously instituted duty hour restrictions had a positive impact on resident quality of life without impacting patient care. Most residents rated their faculty and clinical didactics favorably. However, many residents reported suboptimal preparation in basic neuroscience and practice management issues. Most residents (71%) noted that the Residency In-service Training Examination (RITE) assisted in self-study. A minority of residents (14%) reported that the RITE scores were used for reasons other than self-study. The vast majority (86%) of residents will enter fellowship training following residency and were satisfied with the fellowship offers they received. Conclusions: Graduating residents had largely favorable neurology training experiences. Several common deficiencies include education in basic neuroscience and clinical practice management. Importantly, prior changes to duty hours did not negatively affect the resident perception of neurology residency training. PMID:23091077

    In medical medieval literature some works about dietetics stand out. Dietetics, as a separate branch of medicine, includes not only food or drinks, but other environmental factors influencing on health. They are known as regimina sanitatis or salutis, and specially developed in the Christian west. They generally consisted of a balance between the Galenic "six non-natural things"; factors regulating health and its protection: environment, exercise, food, sleep, bowel movements and emotions. After reviewing the sources and defining the different stages of this genre, we have considered three of the most out-standing medieval regimina, the anonymous Regimen sanitatis salernitanum, Arnaldo de Vilanova's Regimen sanitatis ad regem aragonum and Bernardo de Gordon's Tractatus of conservatione vite humane. In them we review references to neurological disease. Though not independently considered, there is a significant presence of neurological diseases in the regimina. Dietetics measures are proposed to preserve memory, nerves, or hearing, as well as for the treatment of migraine, epilepsy, stroke or dizziness. Regimina are quiet representative among medical medieval literature, and they show medieval physicians vision of neurological diseases. Dietetics was considered useful to preserve health, and therapeutics was based on natural remedies. 2010 Sociedad Española de Neurología. Published by Elsevier Espana. All rights reserved.

    Thyroid hormones exert critical roles throughout the body and play an important and permissive role in neuroendocrine, neurological, and neuromuscular function. We performed a PubMed search through June 2014 with search terms including "hypothyroidism," "hyperthyroidism," "neurological complications," "neuropathy," "myopathy," "congenital hypothyroidism," and "encephalopathy." Relevant publications reviewed included case series, individual case reports, systematic reviews, retrospective analyses, and randomized controlled trials. The neurological outcomes of congenital hypothyroidism were reviewed, along with the clinical features of associated neuromuscular syndromes of both hypothyroidism and hyperthyroidism, including other autoimmune conditions. Evidence for, and pathophysiological controversies surrounding, Hashimoto encephalopathy was also reviewed. The establishment of widespread newborn screening programs has been highly successful in attenuating or preventing early and irreversible neurological harm resulting from congenital thyroid hormone deficiency, but some children continue to display neuromuscular, sensory, and cognitive defects in later life. Acquired disorders of thyroid function such as Hashimoto thyroiditis and Graves' disease are associated with a spectrum of central nervous system and/or neuromuscular dysfunction. However, considerable variation in clinical phenotype is described, and much of our knowledge of the role of thyroid disease in childhood neurological disorders is derived from adult case series. Early and aggressive normalization of thyroxine levels in newborn infants with congenital hypothyroidism is important in minimizing neurological sequelae, but maternal thyroid hormone sources are also critically important to the early developing brain. A spectrum of neurological disorders has been reported in older children with acquired thyroid disease, but the frequency with which these occur remains poorly defined in the literature, and

    81 patients classed into three groups with clinical evidence of neurological symptoms and posttraumatic pain of the cervical spine and the incidence of degenerative disorders were studied noninvasively via CT scanning. In about half of the patients with nerve-root symptomatology as well as with signs of involvement of long tracts, narrowing of the foramen intervertebrale, respectively of the spinal tract, was seen, attributable to degenerative osseous apposition with excellent clinical segmental and (according to radicular symptoms) side correlation. In contrast to these results the group of patients with posttraumatic clinical symptoms showed almost 50% less preexisting degenerative disorders of the cervical spine. Hypertrophic changes of the processus articulares with narrowing of the spinal canal occurred in 14% and were therefore of minor clinical significance. (orig./GDG).

    2014-01-01

    Objective: To ascertain the current status of global health training and humanitarian relief opportunities in US and Canadian postgraduate neurology programs. Background: There is a growing interest among North American trainees to pursue medical electives in low- and middle-income countries. Such training opportunities provide many educational and humanitarian benefits but also pose several challenges related to organization, human resources, funding, and trainee and patient safety. The current support and engagement of neurology postgraduate training programs for trainees to pursue international rotations is unknown. Methods: A survey was distributed to all program directors in the United States and Canada (December 2012–February 2013) through the American Academy of Neurology to assess the training opportunities, institutional partnerships, and support available for international neurology electives. Results: Approximately half of responding programs (53%) allow residents to pursue global health–related electives, and 11% reported that at least 1 trainee participated in humanitarian relief during training (survey response rate 61%, 143/234 program directors). Canadian programs were more likely to allow residents to pursue international electives than US programs (10/11, 91% vs 65/129, 50%, p = 0.023). The number of trainees participating in international electives was low: 0%–9% of residents (55% of programs) and 10%–19% of residents (21% of programs). Lack of funding was the most commonly cited reason for residents not participating in global health electives. If funding was available, 93% of program directors stated there would be time for residents to participate. Most program directors (75%) were interested in further information on global health electives. Conclusions: In spite of high perceived interest, only half of US neurology training programs include international electives, mostly due to a reported lack of funding. By contrast, the majority

    Complementary and alternative medicine (CAM) use in individuals with multiple sclerosis (MS) is common, but its use has been limited by a lack of evidence-based guidance. In March 2014, the American Academy of Neurology published the most comprehensive literature review and evidence-based practice guidelines for CAM use in MS. The guideline author panel reviewed and classified articles according to the American Academy of Neurology therapeutic scheme, and recommendations were linked to the evidence strength. Level A recommendations were found for oral cannabis extract effectiveness in the short term for spasticity-related symptoms and pain and ineffectiveness of ginkgo biloba for cognitive function improvement in MS. Key level B recommendations included: Oral cannabis extract or a synthetic cannabis constituent, tetrahydrocannabinol (THC) is probably ineffective for objective spasticity improvement in the short term; Nabiximols oromucosal cannabinoid spray is probably effective for spasticity symptoms, pain, and urinary frequency, but probably ineffective for objective spasticity outcomes and bladder incontinence; Magnetic therapy is probably effective for fatigue reduction in MS; A low-fat diet with fish oil supplementation is probably ineffective for MS-related relapses, disability, fatigue, magnetic resonance imaging lesions, and quality of life. Several Level C recommendations were made. These included possible effectiveness of gingko biloba for fatigue; possible effectiveness of reflexology for MS-related paresthesias; possible ineffectiveness of the Cari Loder regimen for MS-related disability, symptoms, depression, and fatigue; and bee sting therapy for MS relapses, disability, fatigue, magnetic resonance imaging outcomes, and health-related quality of life. Despite the availability of studies evaluating the effects of oral cannabis in MS, the use of these formulations in United States may be limited due to a lack of standardized, commercial US Food and Drug

    Rates of mental health disorders are significantly greater in children with physical illnesses than in physically well children. Children with neurological conditions, such as epilepsy, are known to have particularly high rates of mental health disorders. Despite this, mental health problems in children with neurological conditions have remained under-recognised and under-treated in clinical settings. Evidence-based guided self-help interventions are efficacious in reducing symptoms of mental health disorders in children, but their efficacy in reducing symptoms of common mental health disorders in children with neurological conditions has not been investigated. We aim to pilot a guided self-help intervention for the treatment of mental health disorders in children with neurological conditions. A pilot randomised controlled trial with 18 patients with neurological conditions and mental health disorders will be conducted. Participants attending specialist neurology clinics at a National UK Children's Hospital will be randomised to receive guided self-help for common mental health disorders or to a 12-week waiting list control. Participants in the treatment group will receive 10 sessions of guided self-help delivered over the telephone. The waiting list control group will receive the intervention after a waiting period of 12 weeks. The primary outcome measure is reduction in symptoms of mental health disorders. Exclusion criteria are limited to those at significant risk of harm to self or others, the presence of primary mental health disorder other than anxiety, depression or disruptive behaviour (e.g. psychosis, eating disorder, obsessive-compulsive disorder) or intellectual disability at a level meaning potential participants would be unable to access the intervention. The study has ethical approval from the Camden and Islington NHS Research Ethics Committee, registration number 14.LO.1353. Results will be disseminated to patients, the wider public, clinicians and

    Full Text Available Introduction: Spasmodic dysphonia (SD is a problem that affects speech and vocalization, one of the most devastating disorders of oral communication. It is characterized by vocal quality tensaestrangulada, harshly and / or interspersed with abrupt vocal attack and a great tension in the vocal tract. The etiology of spasmodic dysphonia is unclear. Some authors point to psychogenic causes, neurological or even unknown. Objective: To assess the prevalence of muscular dystonias and other neurological symptoms in patients with ED. Method: A retrospective study of 10 cases with diagnosis of ED for symptoms and neurological disorders associated. Results: There was a significant predominance of the disease in females (9:1. The average age of onset of symptoms was 32 years, ranging between 14 and 60 years. The mean disease duration was 10 years. Among the patients, 87.5% had a diagnosis of disorders of movement made by a neurologist, including orofacial dystonias (50%, essential tremor (50% and spastic paraparesis (12%. Conclusion: The presence of movement disorders followed almost all cases of spasmodic dysphonia. More studies are needed to clarify the pathophysiological basis of disease.

    Motor and cognitive symptoms are frequent in persons with neurological disorders and often require extensive long-term rehabilitation. Recently, a variety of music-based interventions have been introduced into neurological rehabilitation as training tools. This review aims to 1) describe and define music-based intervention modalities and content which are applied in experimental studies; and 2) describe the effects of these interventions on motor and/or cognitive symptoms in the neurological population. The databases PubMed and Web of Science were searched. Cited references of included articles where screened for potential inclusion. A systematic literature search up to 20th of June 2016 was conducted to include controlled trials and cohort studies that have used music-based interventions for ≥3 weeks in the neurological population (in- and outpatients) targeting motor and/or cognitive symptoms. No limitations to publication date was set. EVIDENCE SYNTHESISː Nineteen articles comprising thirteen randomized controlled trials (total participants Nexp=241, Nctrl=269), four controlled trials (Nexp=59, Nctrl=53) and two cohort studies (N.=27) were included. Fourteen studies were conducted in stroke, three in Parkinson's disease, and two in multiple sclerosis population. Modalities of music-based interventions were clustered into four groups: instrument-based, listening-based, rhythm-based, and multicomponent-based music interventions. Overall, studies consistently showed that music-based interventions had similar or larger effects than conventional rehabilitation on upper limb function (N.=16; fine motricity, hand and arm capacity, finger and hand tapping velocity/variability), mobility (N.=7; gait parameters), and cognition (N.=4; verbal memory and focused attention). CONCLUSIONSː Variety of modalities using music-based interventions has been identified and grouped into four clusters. Effects of interventions demonstrate an improvement in the domains assessed

    Identification of stroke mimics and 'chameleons' among transient neurological deficits (TND) is critical. Diagnostic workup consists of a brain imaging study, for a vascular disease or a brain tumour and EEG, for epileptiform discharges. The precise role of EEG in this diagnostic workup has, however, never been clearly delineated. However, this could be crucial in cases of atypical or incomplete presentation with consequences on disease management and treatment. We analysed the EEG patterns on 95 consecutive patients referred for an EEG within 7 days of a TND with diagnostic uncertainty. Patients were classified at the discharge or the 3-month follow-up visit as: 'ischemic origin', 'migraine aura', 'focal seizure', and 'other'. All patients had a brain imaging study. EEG characteristics were correlated to the TND symptoms, imaging study, and final diagnosis. Sixty four (67%) were of acute onset. Median symptom duration was 45 min. Thirty two % were 'ischemic', 14% 'migraine aura', 19% 'focal seizure', and 36% 'other' cause. EEGs were recorded with a median delay of 1.6 day after symptoms onset. Forty EEGs (42%) were abnormal. Focal slow waves were the most common finding (43%), also in the ischemic group (43%), whether patients had a typical presentation or not. Epileptiform discharges were found in three patients, one with focal seizure and two with migraine aura. Non-specific EEG focal slowing is commonly found in TND, and may last several days. We found no difference in EEG presentation between stroke mimics and stroke chameleons, and between other diagnoses.

    We reviewed the files of 80 successive patients with native and prosthetic valve endocarditis admitted to Riyadh Armed Forces Hospital. Neurolological complications (NC) occurred in 28 (35%) patients. The valves involved were mitral in 12 (43%), aortic in eight (29%), combined mitral and aortic lesions in six (21%) and others in two (7%). The common causative organisms were Streptococci in 12 (43%), Staphylococcus aureus and Staphylococcus epidermides, both occurring in four (14%). Compared to the 52 infective endocarditis patients with no neurological complications (NNC), the NC occurred more frequently in male patients, those with aortic valve lesion, those with atrial fibrillation, those with delayed therapy and those with causative organisms being Streptococci or Staphylococci. Eleven patients died (39%), 12 (43%) recovered with motor sequelae, six (21%) had seizure disorder and five (18%) had full recovery. The frequency of neurological complications and mortality is comparable to those reported in the literature: however, the frequency was higher in our patients. (author)

    Cinema has been defined in many different ways, but most of them agree that it should be considered both a technique and an art. Although films often depict fantasy stories, in many cases they also reflect day-to-day realities. In its earliest days cinema was already attracted to the world of health and sickness, and frequently addressed topics like medical practice, how patients lived with their illnesses, bioethical issues, the relationship between physician and patient or research. To review the presence of neurological pathologies in the cinema with a view to identifying the main neurological disorders that have been portrayed in films. Likewise it also intends to describe the medical praxis that is employed, the relationship between physician and patient, how the experiences of the patient and the family are represented, the adaptation to social and occupational situations, and the intervention of other health care professionals related with neurological patients. Some of the most significant films that have addressed these topics were reviewed and it was seen that in some of them the illness is dealt with in a very true-to-life manner, whereas others tend to include a greater number of inaccuracies and a larger degree of fiction. Cinema has helped to shape certain ways of thinking about the health care professionals who work with neurological patients, the importance of support from the family and the social role, among other things. This confirms that resorting to cinematographic productions is a fruitful tool for stimulating a critical interest in the past and present of medical practice.

  6. VEGF Signaling in Neurological Disorders

    Directory of Open Access Journals (Sweden)

    Joon W. Shim

    2018-01-01

    Full Text Available Vascular endothelial growth factor (VEGF is a potent growth factor playing diverse roles in vasculogenesis and angiogenesis. In the brain, VEGF mediates angiogenesis, neural migration and neuroprotection. As a permeability factor, excessive VEGF disrupts intracellular barriers, increases leakage of the choroid plexus endothelia, evokes edema, and activates the inflammatory pathway. Recently, we discovered that a heparin binding epidermal growth factor like growth factor (HB-EGF—a class of EGF receptor (EGFR family ligands—contributes to the development of hydrocephalus with subarachnoid hemorrhage through activation of VEGF signaling. The objective of this review is to entail a recent update on causes of death due to neurological disorders involving cerebrovascular and age-related neurological conditions and to understand the mechanism by which angiogenesis-dependent pathological events can be treated with VEGF antagonisms. The Global Burden of Disease study indicates that cancer and cardiovascular disease including ischemic and hemorrhagic stroke are two leading causes of death worldwide. The literature suggests that VEGF signaling in ischemic brains highlights the importance of concentration, timing, and alternate route of modulating VEGF signaling pathway. Molecular targets distinguishing two distinct pathways of VEGF signaling may provide novel therapies for the treatment of neurological disorders and for maintaining lower mortality due to these conditions.

    Football players are subjected to repetitive impacts that may lead to brain injury and neurologic dysfunction. Knowledge about head impact exposure (HIE) and consequent neurologic function among youth football players is limited. This study aimed to measure and characterize HIE of youth football players throughout one season and explore associations between HIE and changes in selected clinical measures of neurologic function. Twenty-two youth football players (11-13 yr) wore helmets outfitted with a head impact telemetry (HIT) system to quantify head impact frequency, magnitude, duration, and location. Impact data were collected for each practice (27) and game (9) in a single season. Selected clinical measures of balance, oculomotor performance, reaction time, and self-reported symptoms were assessed before and after the season. The median individual head impacts per practice, per game, and throughout the entire season were 9, 12, and 252, respectively. Approximately 50% of all head impacts (6183) had a linear acceleration between 10g and 20g, but nearly 2% were greater than 80g. Overall, the head impact frequency distributions in this study population were similar in magnitude and location as in high school and collegiate football, but total impact frequency was lower. Individual changes in neurologic function were not associated with cumulative HIE. This study provides a novel examination of HIE and associations with short-term neurologic function in youth football and notably contributes to the limited HIE data currently available for this population. Whereas youth football players can experience remarkably similar head impact forces as high school players, cumulative subconcussive HIE throughout one youth football season may not be detrimental to short-term clinical measures of neurologic function.

    This review is devised to gather the presently known inborn errors of purine metabolism that manifest neurological pediatric syndromes. The aim is to draw a comprehensive picture of these rare diseases, characterized by unexpected and often devastating neurological symptoms. Although investigated for many years, most purine metabolism disorders associated to psychomotor dysfunctions still hide the molecular link between the metabolic derangement and the neurological manifestations. This basically indicates that many of the actual functions of nucleosides and nucleotides in the development and function of several organs, in particular central nervous system, are still unknown. Both superactivity and deficiency of phosphoribosylpyrophosphate synthetase cause hereditary disorders characterized, in most cases, by neurological impairments. The deficiency of adenylosuccinate lyase and 5-amino-4-imidazolecarboxamide ribotide transformylase/IMP cyclohydrolase, both belonging to the de novo purine synthesis pathway, is also associated to severe neurological manifestations. Among catabolic enzymes, hyperactivity of ectosolic 5'-nucleotidase, as well as deficiency of purine nucleoside phosphorylase and adenosine deaminase also lead to syndromes affecting the central nervous system. The most severe pathologies are associated to the deficiency of the salvage pathway enzymes hypoxanthine-guanine phosphoribosyltransferase and deoxyguanosine kinase: the former due to an unexplained adverse effect exerted on the development and/or differentiation of dopaminergic neurons, the latter due to a clear impairment of mitochondrial functions. The assessment of hypo- or hyperuricemic conditions is suggestive of purine enzyme dysfunctions, but most disorders of purine metabolism may escape the clinical investigation because they are not associated to these metabolic derangements. This review may represent a starting point stimulating both scientists and physicians involved in the study of

    The term hypoparathyroidism refers to a group of disorders in which a relative or absolute deficiency of PTH leads to hypocalcemia and hyperphosphatemia. Was to evaluate clinical symptoms in patients with hypoparathyroidism during normocalcemic period and to try to establish its etiology (electrolyte imbalance, organic central nervous system lesions, coincidence of tetany and epilepsy). The analysis included a group of 14 patients with hypoparathyroidism: 3 boys and 11 girls, aged from 12 months to 31 years (median 16.11 years), with duration of the disease 12 months to 26 years (median 10.9 years). In all the patients, the diagnosis was confirmed based on history, physical examination, results of biochemical and hormonal laboratory tests, radiological and neurological examinations. All the patients were followed by endocrinology specialists. Low phosphorus diet, calcium, magnesium, active vitamin D supplementation and management of other endocrine disorders were employed. In 9 patients, pseudo-hypoparathyrodism was diagnosed; of this number, in 8 children, type Ia Albright syndrome was confirmed. Five patients were diagnosed as true hypoparathyroidism, two girls in this group were found to have autoimmune hypoparathyroidism as a component of the autoimmune polyglandular syndrome type 1, 2 others were diagnosed in infancy as congenital hypoparathyroidism and 1 girl had true hypoparathyroidism as a component of Kearns-Sayre syndrome. Five patients were referred to neurological department with epilepsy suspicion. In the medical history, 9 patients had generalized epileptic seizures, moreover, 1 girl manifested absence attack and balance disturbances. In 3 patients, EEG demonstrated changes typical of generalized seizure activity. In 5 patients on anti-epileptic management, additional calcium and active vitamin D treatment was initiated, allowing for achieving seizure remission. CT of the head and pituitary gland showed calcification foci in the central nervous system

  12. Astaxanthin as a Potential Neuroprotective Agent for Neurological Diseases

    2015-09-01

    Full Text Available Neurological diseases, which consist of acute injuries and chronic neurodegeneration, are the leading causes of human death and disability. However, the pathophysiology of these diseases have not been fully elucidated, and effective treatments are still lacking. Astaxanthin, a member of the xanthophyll group, is a red-orange carotenoid with unique cell membrane actions and diverse biological activities. More importantly, there is evidence demonstrating that astaxanthin confers neuroprotective effects in experimental models of acute injuries, chronic neurodegenerative disorders, and neurological diseases. The beneficial effects of astaxanthin are linked to its oxidative, anti-inflammatory, and anti-apoptotic characteristics. In this review, we will focus on the neuroprotective properties of astaxanthin and explore the underlying mechanisms in the setting of neurological diseases.

    Our aim was to investigate whether neurological impairment in chronic Behcet's disease (BD) patients with normal appearing brain can be assessed by means of diffusion-weighted imaging (DWI). The averaged apparent diffusion coefficient (ADC) values were calculated in 22 different radiologically normal appearing brain regions in 32 patients with and without neurological findings and 20 control subjects. The ADC values in bilateral frontal, temporal and occipital normal appearing white matter were significantly higher in the patient groups compared with the control subjects (p<0.05). In these brain regions, DWI revealed differences in the ADC values between patients with neurological findings (including symptomatic and neuro-Behcet patients) and the asymptomatic patient group. The similarity of the ADC values of patients without symptoms to those of the control group allowed clear discrimination between patients with and without neurological findings. DWI may serve to assess subclinical neurological involvement in BD, even when structural changes are absent. (orig.)

    2013-05-01

    We describe a case of a 46-yr-old female who developed hypertension, tachycardia, dysarthria, and leg weakness provoked by pressure changes associated with flying. Typically during the landing phase of flight, she would feel dizzy and note that she had difficulty with speech and leg weakness. After the flight the leg weakness persisted for several days. The symptoms were mitigated when she took a combined alpha-beta blocker (labetalol) prior to the flight. To determine if these symptoms were related to atmospheric pressure change, she was referred for testing in a hyperbaric chamber. She was exposed to elevated atmospheric pressure (maximum 1.2 ATA) while her heart rate and blood pressure were monitored. Within 1 min she developed tachycardia and hypertension. She also quickly developed slurred speech, left arm and leg weakness, and sensory changes in her left leg. She was returned to sea level pressure and her symptoms gradually improved. A full neurological workup has revealed no explanation for these findings. She has no air collections, cysts, or other anatomic findings that could be sensitive to atmospheric pressure change. The pattern is most consistent with a vascular event stimulated by altitude exposure. This case suggests that atmospheric pressure change can produce neurological symptoms, although the mechanism is unknown.

    2016-02-01

    Depressive symptoms are common and economically relevant. Women suffer more often than men do. We analyze associations between social status inconsistency, psychosocial factors, and depressive symptoms stratified by gender. In the present study, 3340 employees of two age cohorts (1959, 1965) working in two waves (2011, 2014) of the prospective German lidA-study and who gave written consent to link register data regarding their employment histories were included. Gender-specific influences of social status inconsistency (deviation of observed income from expected average income based on acquired education) on depressive symptoms and mediation of these associations by work stress in terms of effort-reward-imbalance (ERI) and work-family-conflict (WFC) were analyzed with confirmatory cross-lagged path models. Among men, consistent status (i.e., average income in a specific educational group) increased the frequency of depressive symptoms. No association between negative SSI (i.e., income below the average income given a specific educational attainment) or positive SSI (i.e., income above the average income given a specific educational attainment) and depressive symptoms was observed among men or women. ERI and WFC were longitudinally associated with the outcome and differed slightly regarding gender, i.e., showing stronger effects of ERI for women and of WFC for men. Mediation of the association between social status and depressive symptoms was observed for men and for consistent status (path: consistent status → ERI → depressive symptoms) but not for SSI. ERI and WFC increase the risk of future episodes with depressive symptoms in men and in women irrespective of SSI, occupational position, full- or part-time work, regional factors or individual characteristics.

  18. Dysfunctional HCN ion channels in neurological diseases

    Directory of Open Access Journals (Sweden)

    Jacopo C. DiFrancesco

    2015-03-01

    Full Text Available Hyperpolarization-activated cyclic nucleotide-gated (HCN channels are expressed as four different isoforms (HCN1-4 in the heart and in the central and peripheral nervous systems. HCN channels are activated by membrane hyperpolarization at voltages close to resting membrane potentials and carry the hyperpolarization-activated current, dubbed If (funny current in heart and Ih in neurons. HCN channels contribute in several ways to neuronal activity and are responsible for many important cellular functions, including cellular excitability, generation and modulation of rhythmic activity, dendritic integration, transmission of synaptic potentials and plasticity phenomena. Because of their role, defective HCN channels are natural candidates in the search for potential causes of neurological disorders in humans. Several data, including growing evidence that some forms of epilepsy are associated with HCN mutations, support the notion of an involvement of dysfunctional HCN channels in different experimental models of the disease. Additionally, some anti-epileptic drugs are known to modify the activity of the Ih current. HCN channels are widely expressed in the peripheral nervous system and recent evidence has highlighted the importance of the HCN2 isoform in the transmission of pain. HCN channels are also present in the midbrain system, where they finely regulate the activity of dopaminergic neurons, and a potential role of these channels in the pathogenesis of Parkinson’s disease has recently emerged. The function of HCN channels is regulated by specific accessory proteins, which control the correct expression and modulation of the neuronal Ih current. Alteration of these proteins can severely interfere with the physiological channel function, potentially predisposing to pathological conditions. In this review we address the present knowledge of the association between HCN dysfunctions and neurological diseases, including clinical, genetic and

    Thus far, only a few longitudinal studies investigated the impact of social engagement on health-related quality of life (HRQoL) and depressive symptoms in old age. Therefore, we aimed to examine the impact of social engagement on HRQoL and depressive symptoms in late life. Individuals aged 75 years and over at baseline were interviewed every 1.5 years in a multicenter prospective cohort study in Germany. While HRQoL was quantified by using the Visual Analogue Scale (EQ VAS) of the EQ-5D instrument, depressive symptoms was assessed by using the Geriatric Depression Scale (GDS). Individuals reported the frequency ("never" to "every day") of social engagement (e.g., engagement in the church, as a volunteer, in a party, or in a club) in the last four weeks. Fixed effects regressions were used to estimate the effect of social engagement on the outcome variables. After adjusting for age, marital status, functional status and chronic diseases, fixed effects regressions revealed that the onset of social engagement markedly increased HRQoL and considerably decreased depressive symptoms in the total sample and in women, but not men. Our findings corroborate the relevance of social engagement for HRQoL and depressive symptoms in old age. Encouraging the individuals to start, maintain and expand social engagement in late life might help to maintain and improve HRQoL and decrease depressive symptoms.

  3. Hypnosis as a model of functional neurologic disorders.

    Science.gov (United States)

    Deeley, Q

    2016-01-01

    In the 19th century it was recognized that neurologic symptoms could be caused by "morbid ideation" as well as organic lesions. The subsequent observation that hysteric (now called "functional") symptoms could be produced and removed by hypnotic suggestion led Charcot to hypothesize that suggestion mediated the effects of ideas on hysteric symptoms through as yet unknown effects on brain activity. The advent of neuroimaging 100 years later revealed strikingly similar neural correlates in experiments matching functional symptoms with clinical analogs created by suggestion. Integrative models of suggested and functional symptoms regard these alterations in brain function as the endpoint of a broader set of changes in information processing due to suggestion. These accounts consider that suggestions alter experience by mobilizing representations from memory systems, and altering causal attributions, during preconscious processing which alters the content of what is provided to our highly edited subjective version of the world. Hypnosis as a model for functional symptoms draws attention to how radical alterations in experience and behavior can conform to the content of mental representations through effects on cognition and brain function. Experimental study of functional symptoms and their suggested counterparts in hypnosis reveals the distinct and shared processes through which this can occur. © 2016 Elsevier B.V.

    Our approach is based on a tri-partite method of integrating psychodynamic hypotheses, cognitive subliminal processes, and psychophysiological alpha power measures. We present ten social phobic subjects with three individually selected groups of words representing unconscious conflict, conscious symptom experience, and Osgood Semantic negative valence words used as a control word group. The unconscious conflict and conscious symptom words, presented subliminally and supraliminally, act as primes preceding the conscious symptom and control words presented as supraliminal targets. With alpha power as a marker of inhibitory brain activity, we show that unconscious conflict primes, only when presented subliminally, have a unique inhibitory effect on conscious symptom targets. This effect is absent when the unconscious conflict primes are presented supraliminally, or when the target is the control words. Unconscious conflict prime effects were found to correlate with a measure of repressiveness in a similar previous study (Shevrin et al., 1992, 1996). Conscious symptom primes have no inhibitory effect when presented subliminally. Inhibitory effects with conscious symptom primes are present, but only when the primes are supraliminal, and they did not correlate with repressiveness in a previous study (Shevrin et al., 1992, 1996). We conclude that while the inhibition following supraliminal conscious symptom primes is due to conscious threat bias, the inhibition following subliminal unconscious conflict primes provides a neurological blueprint for dynamic repression: it is only activated subliminally by an individual's unconscious conflict and has an inhibitory effect specific only to the conscious symptom. These novel findings constitute neuroscientific evidence for the psychoanalytic concepts of unconscious conflict and repression, while extending neuroscience theory and methods into the realm of personal, psychological meaning.

    Full Text Available Objective: To observe the conversion disorder in a neurological emergency department. Methods: It is common that the initial approach to this patients include the use of various diagnostic exams. In this series we reviewed 94 patients that arrived a neurological emergency room in a 3 year period.Results: 72 patients were females (76%, and the initial presumptive diagnosis were: neurovascular syndrome in 36 patients (38.3%, convulsive disorder in 20 patients (21.28%, and conversive disorder in 8 patients (8.51%. 82 patients had motor symptoms and 61 sensitive symptoms. 88 patients (93% required neuroimaging studies, 77 (81% patients underwent through basic biochemical panels. Other tests performed were: electroencephalogram in 12 patients (12.77%, electromyography in 11 patients (11.7%, lumbar punction in 8 patients (8.04% and regarding the medical consult in the care of these patients 11 were evaluated by 1 specialists, 35 (37.2% by 2 different specialties, 42 (44.63% patients required evaluation by 3, and 6 patients (6.38% required evaluation by 4 different specialties.Conclusions: Based on this data, we conclude that conversion disorders require a lot of resources in the emergency room and that the similarities with neurological diseases demands a complete workup including expensive diagnostic tools. However, this patients can be discharged safely without requiring hospitalization.

    Examine to what extent adults affected by recent potentially traumatic events (PTE) with different PTSD-symptom levels are more at risk for post-event loneliness than non-affected adults are in the same study period. We extracted data from the Dutch longitudinal LISS panel to measure pre-event loneliness (2011) and post-event loneliness (2013 and 2014), pre-event mental health problems (2011), PTE and PTSD symptoms (2012). This panel is based on a traditional random sample drawn from the population register by Statistics Netherlands. Results of the multinomial logistic regression analyses showed that affected adults with high levels of PTSD symptoms were more at risk for high levels of post-event loneliness than affected adults with very low PTSD-symptom levels and non-affected adults, while controlling for pre-event loneliness, pre-event mental health problems and demographics. However, affected adults with very low levels of PTSD symptoms compared to non-affected adults were less at risk for medium and high levels of post-event loneliness while controlling for the same variables. Yet, pre-event loneliness appeared to be the strongest independent predictor of loneliness at later stages: more than 80% with high pre-event levels had high post-event levels at both follow-ups. Remarkably, potentially traumatic events have depending on PTSD-symptom levels both negative and positive effects on post-event loneliness in favor of affected adults with very low PTSD symptoms levels. However, post-event levels at later stages are predominantly determined by pre-event loneliness levels.

    The demographic change leads to a shrinking German work force. Depressive symptoms cause many days absent at work, loss of productivity and early retirement. Therefore, pathways for prevention of depressive symptoms are important for the maintenance of global competitiveness. We investigated the role of work-family conflict (WFC) in the well-known association between work stress and depressive symptoms. A total of 6,339 employees subject to social insurance, born in 1959 or 1965 and randomly drawn from 222 sample points in Germany participated in the first wave of the leben in der Arbeit-study. In the analysis, 5,906 study subjects working in full-time or part-time positions were included. Work stress was measured by effort-reward imbalance ratio, depressive symptoms by the applied Becks depression inventory (BDI-V) and WFC by items of the Copenhagen Psychosocial Questionnaire (COPSOQ)-scale. Multiple linear regression analysis adjusted for age, education, negative affectivity (PANAS), overcommitment and number of children was performed. Mediation was defined according to the criteria of Baron and Kenny. Work stress was significantly associated with depressive symptoms (BDI-V) in all full-time [ß1female = 6.61 (95 % CI 3.95-9.27); ß1male = 8.02 (95 % CI 5.94-10.09)] and female part-time employees [ß2female = 4.87 (95 % CI 2.16-7.59)]. When controlling for WFC effect, estimates became smaller in men and were even halved in women. WFC was also significantly associated with work stress and depressive symptoms: All criteria for partial mediation between work stress and depressiveness were fulfilled. Prevention of WFC may help to reduce days absent at work and early retirement due to work stress-related depressive symptoms in middle-aged women and men.

    To systematically review evidence bearing on the management of patients with amyotrophic lateral sclerosis (ALS). The authors analyzed studies from 1998 to 2007 to update the 1999 practice parameter. Topics covered in this section include slowing disease progression, nutrition, and respiratory management for patients with ALS. The authors identified 8 Class I studies, 5 Class II studies, and 43 Class III studies in ALS. Important treatments are available for patients with ALS that are underutilized. Noninvasive ventilation (NIV), percutaneous endoscopic gastrostomy (PEG), and riluzole are particularly important and have the best evidence. More studies are needed to examine the best tests of respiratory function in ALS, as well as the optimal time for starting PEG, the impact of PEG on quality of life and survival, and the effect of vitamins and supplements on ALS. Riluzole should be offered to slow disease progression (Level A). PEG should be considered to stabilize weight and to prolong survival in patients with ALS (Level B). NIV should be considered to treat respiratory insufficiency in order to lengthen survival (Level B) and to slow the decline of forced vital capacity (Level B). NIV may be considered to improve quality of life (Level C) [corrected].Early initiation of NIV may increase compliance (Level C), and insufflation/exsufflation may be considered to help clear secretions (Level C).

    A radiographic study was conducted to determine the incidence of redundant nerve roots of the cauda equina (RNR) in neurologically asymptomatic patients, and to clarify whether RNR has an impact on the clinical symptom. 50 patients who had spine disease such as spondylosis and compression fracture were examined by MRI. They didn't have neurological symptom such as sciatica, leg numbness, and motor weakness of lower extremities. There were 18 men and 32 women, and their mean age was 72.4 years (range: 32-87 years). RNR was found in 18 of the 50 patients (36.0%) and in a higher percentage of the patients who had lumber spinal canal stenosis. We concluded that RNR was only a morphological change of the cauda equine and had little effect on the neurological symptom. (author)

  11. VPA alleviates neurological deficits and restores gene expression in a mouse model of Rett syndrome.

    Full Text Available Rett syndrome (RTT is a devastating neurodevelopmental disorder that occurs once in every 10,000-15,000 live female births. Despite intensive research, no effective cure is yet available. Valproic acid (VPA has been used widely to treat mood disorder, epilepsy, and a growing number of other disorders. In limited clinical studies, VPA has also been used to control seizure in RTT patients with promising albeit somewhat unclear efficacy. In this study we tested the effect of VPA on the neurological symptoms of RTT and discovered that short-term VPA treatment during the symptomatic period could reduce neurological symptoms in RTT mice. We found that VPA restores the expression of a subset of genes in RTT mouse brains, and these genes clustered in neurological disease and developmental disorder networks. Our data suggest that VPA could be used as a drug to alleviate RTT symptoms.

    Common mental disorders are a major contributor to the burden of disease in developing countries. An assessment was carried out of whether food insecurity and exposure to stressful life events, two common features of life in sub-Saharan Africa (SSA), are associated with symptoms of mental disorders among adults. The Gilgel Gibe Growth and Development Study (GGGDS) is an ongoing cohort study in rural Ethiopia. Participants of the GGGDS were randomly selected from households from a complete census of persons living in the area. The Hopkins Symptom Checklist and the Harvard Trauma Questionnaire were used to assess anxiety and depression and post-traumatic stress symptoms. Among 902 adult participants, food insecurity, stressful life events and symptoms of common mental disorders were highly prevalent. In separate multivariate models adjusting for potential confounders, food insecurity and stressful life events were independently associated with high symptoms of depression, anxiety and post-traumatic stress. Potentially modifiable stressors may influence variation in common mental disorders in Ethiopia, and SSA more generally. These findings suggest that the negative effects of food insecurity extend beyond nutritional outcomes and that interventions that promote food security may also positively influence adult mental health in the region.

    Stenosis of central veins (brachiocephalic vein [BCV] and superior vena cava) occurs in 30% of hemodialysis patients, rarely producing intracranial pathology. The authors present the first cases of BCV stenosis causing perimesencephalic subarachnoid hemorrhage and myoclonic epilepsy. In the first case, a 73-year-old man on hemodialysis presented with headache and blurry vision, and was admitted with presumed idiopathic intracranial hypertension after negative CT studies and confirmatory lumbar puncture. The patient mildly improved until hospital Day 3, when he experienced a seizure; emergency CT scans showed perimesencephalic subarachnoid hemorrhage. Cerebral angiography failed to find any vascular abnormality, but demonstrated venous congestion. A fistulogram found left BCV occlusion with jugular reflux. The occlusion could not be reopened percutaneously and required open fistula ligation. Postoperatively, symptoms resolved and the patient remained intact at 7-month follow-up. In the second case, a 67-year-old woman on hemodialysis presented with right arm weakness and myoclonic jerks. Admission MRI revealed subcortical edema and a possible dural arteriovenous fistula. Cerebral angiography showed venous engorgement, but no vascular malformation. A fistulogram found left BCV stenosis with jugular reflux, which was immediately reversed with angioplasty and stent placement. Postprocedure the patient was seizure free, and her strength improved. Seven months later the patient presented in myoclonic status epilepticus, and a fistulogram revealed stent occlusion. Angioplasty successfully reopened the stent and she returned to baseline; she was seizure free at 4-month follow-up. Central venous stenosis is common with hemodialysis, but rarely presents with neurological findings. Prompt recognition and endovascular intervention can restore normal venous drainage and resolve symptoms.

    It has been suggested that prenatal maternal stress may increase the risk of childhood externalizing disorders, yet no large cohort study has investigated this association across a large range of acute stressors. Our objective was to estimate the association between prenatal stressful events and risk of offspring conduct disorder and hyperactivity. We used data from 10,184 mother-offspring pairs from the United Kingdom-based Avon Longitudinal Study of Parents and Children. Mothers self-reported 42 prenatal stressful life events at 18 weeks' gestation. Symptoms of conduct disorder and hyperactivity in their offspring were measured at 6, 9, 11, 13, and 16 years of age using the Strengths and Difficulties Questionnaire. The primary outcome was membership in high-symptom trajectories of 1) conduct disorder and 2) hyperactivity throughout childhood, identified using latent class growth modeling. Multinomial logistic regression models estimated the association between prenatal stress and both conduct disorder and hyperactivity, after adjusting for sex, parental education, low birth weight, preterm birth, parental social class, maternal smoking and drinking, maternal mental health, offspring stressful life events, and offspring depressive and anxious symptoms. Those exposed to the highest quartile of prenatal stress were more likely to belong to the high symptom trajectory for hyperactivity (B = 0.46, p < .05) and conduct disorder (B = 0.88, p < .01), respectively. Prenatal stress further demonstrated a positive, dose-response relationship with symptoms of externalizing disorders at independent time points. The findings suggest that prenatal stressful events may be an independent risk factor for offspring externalizing symptoms, regardless of maternal mental health and offspring internalizing.

    Deficits in central, subcortical dopamine (DA) signaling may underlie negative symptom severity, particularly anhedonia, in healthy individuals and in schizophrenia. To investigate these relationships, we assessed negative symptoms with the Schedule for the Assessment of Negative Symptoms and the Brief Negative Symptom Scale (BNSS) and self-reported anhedonia with the Scales for Physical and Social Anhedonia (SPSA), Temporal Experience of Pleasure Scale, and Snaith-Hamilton Pleasure Scale in 36 healthy controls (HC), 27 siblings (SIB) of individuals with schizophrenia, and 66 individuals with schizophrenia or schizoaffective disorder (SCZ). A subset of participants (N = 124) were genotyped for DA-related polymorphisms in genes for DRD4, DRD2/ANKK1, DAT1, and COMT, which were used to construct biologically-informed multi-locus genetic profile (MGP) scores reflective of subcortical dopaminergic signaling. DA receptor type 2 (D2R) binding was assessed among a second subset of participants (N = 23) using PET scans with the D2R-selective, non-displaceable radioligand (N-[ 11 C]methyl)benperidol. Higher MGP scores, reflecting elevated subcortical dopaminergic signaling capacity, were associated with less negative symptom severity, as measured by the BNSS, across all participants. In addition, higher striatal D2R binding was associated with less physical and social anhedonia, as measured by the SPSA, across HC, SIB, and SCZ. The current preliminary findings support the hypothesis that subcortical DA function may contribute to negative symptom severity and self-reported anhedonia, independent of diagnostic status.

    Extra-oesophageal symptoms of gastro-oesophageal reflux disease (GORD) are often studied, but remain a subject of debate. It has been clearly shown that there is a relationship between the extra-oesophageal symptoms chronic cough, asthma, laryngitis and dental erosion and GORD. Literature is abundant concerning reflux-related cough and reflux-related asthma, but much less is known about reflux-related dental erosions. The prevalence of dental erosion in GORD and vice versa, the prevalence of GORD in patients with dental erosion is high but the exact mechanism of reflux-induced tooth wear erosion is still under review.

    Full Text Available Magnesium is the second most common intracellular cation and serves as an important metabolic cofactor to over 300 enzymatic reactions throughout the human body. Among its various roles, magnesium modulates calcium entry and release from sarcoplasmic reticulum and regulates ATP pumps in myocytes and neurons, thereby regulating cardiac and neuronal excitability. Therefore, deficiency of this essential mineral may result in serious cardiovascular and neurologic derangements. In this case, we present the clinical course of a 76-year-old woman who presented with marked cardiac and neurological signs and symptoms which developed as a result of severe hypomagnesemia. The patient promptly responded to magnesium replacement once the diagnosis was established. We herein discuss the clinical presentation, pathophysiology, diagnosis, and management of severe hypomagnesemia and emphasize the implications of magnesium deficiency in the cardiovascular and central nervous systems. Furthermore, this case highlights the importance of having high vigilance for hypomagnesemia in the appropriate clinical setting.

    The objective of this review is to highlight the impact of insomnia in central neurological disorders by providing information on its prevalence and give recommendations for diagnosis and treatment. Insomnia in neurological disorders is a frequent, but underestimated symptom. Its occurrence may...... be a direct consequence of the disease itself or may be secondary to pain, depression, other sleep disorders or the effects of medications. Insomnia can have a significant impact on the patient's cognitive and physical function and may be associated with psychological distress and depression. Diagnosis...... of insomnia is primarily based on medical history and validated questionnaires. Actigraphy is a helpful diagnostic tool for assessing the circadian sleep-wake rhythm. For differential diagnosis and to measure the duration of sleep full polysomnography may be recommended. Prior to initiating treatment...

    Full Text Available Zika virus (ZIKV is an emerging flavivirus rapidly spreading throughout the tropical Americas. Aedes mosquitoes is the principal way of transmission of the virus to humans. ZIKV can be spread by transplacental, perinatal, and body fluids. ZIKV infection is often asymptomatic and those with symptoms present minor illness after 3 to 12 days of incubation, characterized by a mild and self-limiting disease with low-grade fever, conjunctivitis, widespread pruritic maculopapular rash, arthralgia and myalgia. ZIKV has been linked to a number of central and peripheral nervous system injuries such as Guillain-Barré syndrome (GBS, transverse myelitis (TM, meningoencephalitis, ophthalmological manifestations, and other neurological complications. Nevertheless, mechanisms of host-pathogen neuro-immune interactions remain incompletely elucidated. This review provides a critical discussion about the possible mechanisms underlying the development of autoimmune neurological conditions associated with Zika virus infection.

    Full Text Available Hypertension is one of the most common vascular diseases. The brain as target organs in hypertension is damaged more often and earlier. Neurological complications due to hypertension are frequently hyperdiagnosed in Russian neurological practice. Thus, headache, dizziness, impaired recall of recent events, nocturnal sleep disorders, and many other complaints in a hypertensive patient are usually regarded as a manifestation of dyscirculatory encephalopathy. At the same time headaches (tension headache and migraine in hypertensive patients are predominantly primary; headache associated with dramatic marked elevations in blood pressure is encountered in only a small number of patients. The role of cerebrovascular diseases in the development of dizziness in hypertensive patients is also overestimated. The vast majority of cases, patients with this complaint are in fact identified to have benign paroxysmal postural vertigo, Mеniеre’s disease, vestibular neuronitis, or vestibular migraine. Psychogenic disorders or multisensory insufficiency are generally responsible for non-systemic vertigo in hypertensive patients. Chronic cerebral circulatory insufficiency may cause non-systemic vertigo as a subjective equivalent of postural instability.Cognitive impairments (CIs are the most common and earliest manifestation of cerebrovascular lesion in hypertension. In most cases, CIs in hypertension were vascular and associated with cerebrovascular lesion due to lacunar infarcts and leukoaraiosis. However, mixed CIs frequently occur when hypertensive patients are also found to have signs of a degenerative disease, most commonly in Alzheimer’s disease.

    ABSTRACT This systematic review and meta-analysis (MA) investigates the impact of elevated blood phenylalanine (Phe) on neuropsychiatric symptoms in adults with phenylketonuria (PKU). The meta-analysis of PKU is challenging because high-quality evidence is lacking due to the limited number of affected individuals and few placebo-controlled, double-blind studies of adults with high and low blood Phe. Neuropsychiatric symptoms associated with PKU exceed general population estimates for inattention, hyperactivity, depression, and anxiety. High Phe is associated with an increased prevalence of neuropsychiatric symptoms and executive functioning deficits whereas low Phe is associated with improved neurological performance. Findings support lifelong maintenance of low blood Phe. PMID:27805419

    OBJECTIVE The aim of this study was to assess the outcome of neurosurgical treatment in children with bleeding diathesis and also to evaluate the current management plan applied in the authors' service. METHODS The authors retrospectively analyzed all cases in which neurosurgical procedures were performed in pediatric patients presenting with intracranial hematoma due to an underlying bleeding tendency over a 5-year period at their institution. They evaluated the patients' neurological symptoms from the initial referral, hematological abnormalities, surgical treatment, neurological outcome, and scores on the Pediatric Glasgow Outcome Scale-Extended (GOS-E Peds) obtained 1 year after the last operation. RESULTS Five patients with a bleeding diathesis who underwent surgery for intracranial hematoma were identified; the diagnosis was hemophilia A in 3 cases, idiopathic thrombocytopenic purpura in 1 case, and severe aplastic anemia in 1 case. Intracerebral hematoma (ICH) (n = 4) and acute subdural hematoma (n = 1) were confirmed on radiological investigations. In 2 of the 4 patients with ICH, the diagnosis of bleeding diathesis was made for the first time on presentation. Four patients (all male) were younger than 2 years; the patient with severe aplastic anemia and spontaneous ICH was 15 years old and female. The duration of symptoms varied from 24 hours to 5 days. Neurological examination at 1 year's follow-up showed complete recovery (GOS-E Peds score of 1) in 3 cases and mild weakness (GOS-E Peds score of 2) in 2 cases. CONCLUSIONS Neurosurgical management of patients with bleeding diathesis should be carried out in a tertiary-care setting with multidisciplinary team management, including members with expertise in neuroimaging and hematology, in addition to neurosurgery. Early diagnosis and prompt treatment of a bleeding diathesis is crucial for full neurological recovery.

    Neuropsychiatric symptoms may represent an atypical manifestation of celiac disease that occur before a gastroenterological diagnosis is made. Some studies suggest that a gluten-free diet is effective in treating the depression, anxiety, and neurological complications associated with celiac disease. The article describes the case of a patient suffering from chronic, treatment-resistant symptoms of depression and anxiety. The diagnosis of celiac disease and introduction of an elimination diet caused a significant improvement in mental state and everyday functioning in the presenting patient. The presence of persistent anxiety and depressive symptoms, with a poor reaction to pharmacological treatment, indicates a need to identify somatic reasons for the underlying condition. It is important to remember that celiac disease can occur at any age, not only in childhood. The presence of this somatic cause of persistent depressive and anxiety symptoms should be considered in the diagnostic process in adults.

    Full Text Available Background: World Health Organization declared pandemic phase of human infection with novel influenza A (H1N1 in April 2009. There are very few reports about the neurological complications of H1N1 virus infection in the literature. Occasionally, these complications are severe and even fatal in some individuals. The aims of this study were to report neurological complaints and/or complications associated with H1N1 virus infection. Methods: The medical files of all patients with H1N1 influenza infection admitted to a specified hospital in the city of Shiraz, Iran from October through November 2009 were reviewed. More information about the patients were obtained by phone calls to the patients or their care givers. All patients had confirmed H1N1 virus infection with real-time PCR assay. Results: Fifty-five patients with H1N1 infection were studied. Twenty-three patients had neurological signs and/or symptoms. Mild neurological complaints may be reported in up to 42% of patients infected by H1N1 virus. Severe neurological complications occurred in 9% of the patients. The most common neurological manifestations were headache, numbness and paresthesia, drowsiness and coma. One patient had a Guillain-Barre syndrome-like illness, and died in a few days. Another patient had focal status epilepticus and encephalopathy. Conclusions: The H1N1 infection seems to have been quite mild with a self-limited course in much of the world, yet there appears to be a subset, which is severely affected. We recommend performing diagnostic tests for H1N1influenza virus in all patients with respiratory illness and neurological signs/symptoms. We also recommend initiating treatment with appropriate antiviral drugs as soon as possible in those with any significant neurological presentation accompanied with respiratory illness and flu-like symptoms

    Background. Magnetic resonance imaging (MRI) is the recommended primary investigation method for metastatic spinal cord compression (MSCC). Initiating treatment before the development of motor deficits is essential to preserve neurological function. However, the relationship between MRI-assessed grades of spinal metastatic disease and neurological status has not been widely investigated. Purpose. To analyze the association between neurological function and MRI-based assessment of the extent of spinal metastases using two different grading systems. Material and Methods. A total of 284 patients admitted to our institution for initial radiotherapy or surgery for symptomatic spinal metastases were included in the study. Motor and sensory deficits were categorized according to the Frankel classification system. Pre-treatment MRI evaluations of the entire spine were scored for the extent of spinal metastases, presence and severity of spinal cord compression, and nerve root compression. Two MRI-based scales were used to evaluate the degree of cord compression and spinal canal narrowing and relate these findings to neurological function. Results. Of the patients included in the study, 28 were non-ambulatory, 49 were ambulatory with minor motor deficits, and 207 had normal motor function. Spinal cord compression was present in all patients with Frankel scores of B or C, 23 of 35 patients with a Frankel score of D (66%), and 48 of 152 patients with a Frankel score of E (32%). The percentage of patients with severe spinal canal narrowing increased with increasing Frankel grades. The grading according to the scales showed a significant association with the symptoms according to the Frankel scale (P < 0.001). Conclusion. In patients with neurological dysfunction, the presence and severity of impairment was associated with the epidural tumor burden. A significant number of patients had radiological spinal cord compression and normal motor function (occult MSCC)

    Autoimmune neurological syndrome is a group of disorders caused by cancer affecting nervous system by different immunological mechanisms. In this study, we aim to study the clinical symptoms, cerebrospinal fluid (CSF) findings, autoantibody tests, computed tomography (CT), magnetic resonance imaging (MRI) signs and treatment outcome of patients with autoimmune syndromes. In this study, 7 patients (4 male, 3 female) diagnosed with autoimmune neurological syndrome were retrospectively examined. Five of patients were diagnosed with limbic encephalitis, two of them were paraneoplastic cerebellar degeneration. Confusion and seizure were the most seen symptoms. Two patients had psychiatric disturbances (28,5%) followed by seizure. Headache was seen in 2 patients (% 28,5), disartria in 1 patient (% 14,2), and gait disorder in 2 patients (28,5%). The duration of symptoms was 46 (3-150) days on average. CSF abnormalities were detected in 2 patients. CT and MRI of the brain was available in all patients. Five patients had involvement of mesiotemporal region, two patients had diffuse cerebellar atrophy. One of patients had anti-GABAR B1 positivity. Tumors were detected in 2 patients while investigation for paraneoplasia screening. Remission is only possible with the detection and treatment of the malignancy. Early diagnosis and treatment are of paramount importance. Copyright © 2016 Elsevier Ireland Ltd. All rights reserved.

  10. Telomere Shortening in Neurological Disorders: An Abundance of Unanswered Questions

    OpenAIRE

    Eitan, Erez; Hutchison, Emmette R.; Mattson, Mark P.

    2014-01-01

    Telomeres, ribonucleoprotein complexes that cap eukaryotic chromosomes, typically shorten in leukocytes with aging. Aging is a primary risk factor for neurodegenerative disease (ND), and a common assumption has arisen that leukocyte telomere length (LTL) can serve as a predictor of neurological disease. However, the evidence for shorter LTL in Alzheimer’s and Parkinson’s patients is inconsistent. The diverse causes of telomere shortening may explain variability in LTL between studies and indi...

    Full Text Available This state-of-the art paper focuses on the poorly explored issue of foreign language aptitude, attempting to present the latest developments in this field and reconceptualizations of the construct from the perspective of neuroscience. In accordance with this goal, it first discusses general directions in neurolinguistic research on foreign language aptitude, starting with the earliest attempts to define the neurological substrate for talent, sources of difficulties in the neurolinguistic research on foreign language aptitude and modern research methods. This is followed by the discussion of the research on the phonology of foreign language aptitude with emphasis on functional and structural studies as well as their consequences for the knowledge of the concept. The subsequent section presents the studies which focus on lexical and morphosyntactic aspects of foreign language aptitude. The paper ends with a discussion of the limitations of contemporary research, the future directions of such research and selec ed methodological issues.

    The exploration of brain epigenomes, which consist of various types of DNA methylation and covalent histone modifications, is providing new and unprecedented insights into the mechanisms of neural development, neurological disease and aging. Traditionally, chromatin defects in the brain were considered static lesions of early development that occurred in the context of rare genetic syndromes, but it is now clear that mutations and maladaptations of the epigenetic machinery cover a much wider continuum that includes adult-onset neurodegenerative disease. Here, we describe how recent advances in neuroepigenetics have contributed to an improved mechanistic understanding of developmental and degenerative brain disorders, and we discuss how they could influence the development of future therapies for these conditions.

    A variety of neurological problems have affected the lives of giants in the jazz genre. Cole Porter courageously remained prolific after severe leg injuries secondary to an equestrian accident, until he succumbed to osteomyelitis, amputations, depression, and phantom limb pain. George Gershwin resisted explanations for uncinate seizures and personality change and herniated from a right temporal lobe brain tumor, which was a benign cystic glioma. Thelonious Monk had erratic moods, reflected in his pianism, and was ultimately mute and withdrawn, succumbing to cerebrovascular events. Charlie Parker dealt with mood lability and drug dependence, the latter emanating from analgesics following an accident, and ultimately lived as hard as he played his famous bebop saxophone lines and arpeggios. Charles Mingus hummed his last compositions into a tape recorder as he died with motor neuron disease. Bud Powell had severe posttraumatic headaches after being struck by a police stick defending Thelonious Monk during a Harlem club raid.

    Paraneoplastic neurological syndromes (PNS) are caused by immune responses against neuronal antigens expressed by the tumor. Based on the immunological pathomechanisms and responsiveness of treatments, onconeuronal antibodies are divided into two categories: 1) antibodies against neural intracellular antigens and 2) antibodies against neuronal surface or synaptic antigens. The recent discovery of onconeuronal antibodies have radically changed concepts of CNS autoimmunity, including PNS. The recognition of PNS provides a foundation for the early detection of underlying tumors and initiations of prompt treatments, which can result in substantial improvement. We here review the characteristic onconeuronal antibodies, including anti-Hu, anti-Ma2, and anti-N-methyl-D-aspartate receptor, and discuss the algorithm for the diagnosis of PNS.

    To identify and describe late neurological complications in a Danish testis cancer cohort treated by radiotherapy. Clinical retrospective material of 94 consecutive patients with malignant testicular tumours treated at Aarhus County Hospital from 1964 to 1973. The irradiated dose in the paraaortic field varied from 27 to 55 Gy given 5 or 6 days a week, from the back and front alternately. The biological equivalent dose of the spinal cord was calculated using the linear-quadratic model. Median follow-up was 25 years, range 7 to 33 years. Seven patients were identified with late neurological complications after irradiation. One developed symptoms 9 months after treatment, but in the six other cases we found a latency period between 10 and 20 years from radiotherapy until the initial neurological symptoms began. The clinical picture in all seven patients was dominated by muscle atrophy, flaccid paresis in the lower limbs and absence of sphincter disturbances or sensory symptoms. High spinal cord dose was related to increased risk of neurological damage. During follow-up 19 patients developed another primary cancer in the radiation field; nine patients were diagnosed with severe arteriosclerosis and 13 patients with long-term gastrointestinal morbidity. Seven patients were identified with late neurological complications, and a clear dose-incidence relationship was shown. The latency period, from irradiation to the initial neurological symptoms began, ranged from 9 months to 20 years with progression of symptoms beyond 25 years. Furthermore many patients in the cohort suffered from solid tumours in the radiation field, severe arteriosclerosis and long-term gastrointestinal morbidity

    The correlations between neurological soft signs (NSS) in children with attention deficit hyperactivity disorder (ADHD) and their executive function, symptoms of inattention, and hyperactivity-impulsivity and the NSS of their parents remain unclear. This study aimed to examine: (1) the prevalence of NSS in children with ADHD and their parents; (2) the correlation between the NSS of children with ADHD and the NSS of their parents; and (3) the correlation between the NSS of children with ADHD and their executive function and symptoms. NSS were assessed with the Cambridge Neurological Inventory (CNI) in 57 children with ADHD (and 80 parents) and 60 healthy children (and 75 parents). Executive function was measured with the Behavioral Rating Inventory of Executive Function (BRIEF). Children with ADHD and their parents had significantly higher NSS than normal children and their parents, respectively, and the NSS of children with ADHD were correlated more strongly with the NSS of their fathers than their mothers. No correlation was found between NSS and BRIEF executive function, but Disinhibition in children with ADHD was significantly correlated with hyperactivity-impulsivity symptoms. Paternal and maternal NSS provided different predictions for child NSS. It may be that NSS are more likely to be genetically transmitted by fathers. Copyright © 2015 Elsevier Ireland Ltd.

    Evidence-based guidelines for the management of neurological disease and lower urinary tract dysfunction have been produced by the International Consultations on Incontinence (ICI). These are comprehensive guidelines, and were developed to have world-wide relevance. To update clinical management of neurogenic bladder dysfunction from the recommendations of the fourth ICI, 2009. A series of evidence reviews and updates were performed by members of the working group. The resulting guidelines were presented at the 2012 meeting of the European Association of Urology for consultation, and consequently amended to deliver evidence-based conclusions and recommendations in 2013. The current review is a synthesis of the conclusions and recommendations, including the algorithms for initial and specialized management of neurogenic lower urinary tract dysfunction. The pathophysiology is categorized according to the nature of onset of neurological disease and the part(s) of the nervous system affected. Assessment requires clinical evaluation, general investigations, and specialized testing. Treatment primarily focuses on ensuring safety of the patient and optimizing quality of life. Symptom management covers conservative and interventional measures to aid urine storage and bladder emptying, along with containment of incontinence. A multidisciplinary approach to management is essential. The review offers a pragmatic review of management in the context of complex pathophysiology and varied evidence base. Neurourol.

    Disorders of mineral metabolism may cause neurologic manifestations of the central and peripheral nervous systems. This is because plasma calcium stabilizes excitable membranes in the nerve and muscle tissue, magnesium is predominantly intracellular and is required for activation of many intracellular enzymes, and extracellular magnesium affects synaptic transmission. This chapter reviews abnormalities in electrolytes and minerals which can be associated with several neuromuscular symptoms including neuromuscular irritability, mental status changes, cardiac and smooth muscle changes, etc. © 2014 Elsevier B.V.

    Polycythemia vera, a clonal stem cell disorder, produces neurologic problems in 50-80% of patients. Some symptoms, such as headache and dizziness, are related to hyperviscosity, and respond immediately to reduction of cell counts. Others seem to result from an associated coagulopathy. Patients with polycythemia tend to develop both arterial and venous thrombosis and are prone to hemorrhages. Treatments for polycythemia include phlebotomy, chlorambucil supplemented with phlebotomy, and 32 P plus phlebotomy. Whatever treatment is chosen, the aim of therapy should be to reduce the hematocrit to approximately 40-45%.37 references

    Frontotemporal degeneration (FTD) in its behavioral variant (bvFTD) is probably one of the conditions that best illustrates the links between psychiatry and neurology. It is indeed admitted that between a third and half of patients with this condition, especially in early-onset forms, receive an initial diagnosis of psychiatric disorder (depression, schizophrenia, bipolar disorder) and are then referred to a psychiatric ward. BvFTD can thus be considered a neurological disorder with a psychiatric presentation. Among psychiatric symptoms reported in this disease, psychotic symptoms (hallucinations, delusions, especially of persecution), which have long been underestimated in bvFTD and are not part of the current diagnostic criteria, are present in about 20% of cases and may be inaugural. They are particularly common in the genetic forms related to a mutation in the C9orf72 gene (up to 50%), and to a lesser extent in the GRN gene (up to 25%). C9orf72 gene mutation is often associated with a family history of dementia or motor neuron disease but also of psychiatric disorders. It has also been described in sporadic presentation forms. Sometimes, the moderate degree of brain atrophy on MRI described in patients carrying this mutation may complicate the differential diagnosis with late-onset psychiatric diseases. In the present article, we underline the importance of considering that psychiatric - especially psychotic - symptoms are not rare in bvFTD, which should lead to a revision of the diagnostic criteria of this disease by taking greater account of this fact. We also propose a diagnostic chart, based on concerted evaluation by neurologists and psychiatrists for cases of atypical psychiatric symptoms (late-onset or pharmacoresistant troubles) leading to consider the possibility of a neurological disorder, in order to shed a new light on these difficult clinical situations. In the field of research, bvFTD may constitute a model to explore the neural basis of certain

    The course-heterogeneity of Major Depressive Disorder (MDD) hampers development of better prognostic models. Although latent class growth analyses (LCGA) have been used to explain course-heterogeneity, such analyses have failed to also account for symptom-heterogeneity of depressive symptoms. Therefore, the aim was to identify more specific data-driven subgroups based on patterns of course-trajectories on different depressive symptom domains. In primary care MDD patients (n=205), the presence of the MDD criterion symptoms was determined for each week during a year. Weekly 'mood/cognition' (MC) and 'somatic' (SOM) scores were computed and parallel processes-LCGA (PP-LCGA) was used to identify subgroups based on the course on these domains. The classes׳ associations with baseline predictors and 2-/3-year outcomes were investigated. PP-LCGA identified four classes: quick recovery, persisting SOM, persisting MC, and persisting SOM+MC (chronic). Persisting SOM was specifically predicted by higher baseline somatic symptomatology and somatization, and was associated with more somatic depressive symptomatology at long-term follow-up. Persisting MC was specifically predicted by higher depressive severity, thinking insufficiencies, neuroticism, loneliness and lower self-esteem, and was associated with lower mental health related quality of life and more mood/cognitive depressive symptomatology at follow-up. The sample was small and contained only primary care MDD patients. The weekly depression assessments were collected retrospectively at 3-month intervals. The results indicate that there are two specific prototypes of depression, characterized by either persisting MC or persisting SOM, which have different sets of associated prognostic factors and long-term outcomes, and could have different etiological mechanisms.

    Interpersonal psychotherapy (IPT) has demonstrated efficacy for the treatment of depression, yet little is known about its therapeutic mechanisms. As a specific treatment, IPT has been shown to directly reduce depressive symptoms, although it is unclear whether these reductions occur via interpersonal changes. Within IPT, the potential role of the working alliance, a common factor, as a predictor of depression and interpersonal changes is also unclear. Participants were 147 depressed persons living with HIV in rural communities of 28 U.S. states enrolled in a randomized clinical trial. Seventy-five patients received up to 9 sessions of telephone-administered IPT (tele-IPT) plus standard care and 72 patients received standard care only. Two models were tested; one included treatment condition (tele-IPT vs. control) and another included the working alliance as independent variables. The first model found an indirect effect whereby tele-IPT reduced depression via decreased social avoidance. There was a direct effect between tele-IPT and reduced depression. In the second model, the working alliance influenced depressive symptom relief via reductions in social avoidance. Both goal and task working alliance subscales were indirectly associated with reductions in depressive symptoms, also through reductions in social avoidance. There were no direct effects involving the working alliance. Tele-IPT's influence on depressive symptom reduction was primarily through a direct effect, whereas the influence of working alliance depression was almost entirely via an indirect effect through interpersonal problems. Study findings have implications for IPT when intervening with depressed rural people living with HIV/AIDS over the telephone. © 2017 Wiley Periodicals, Inc.

    Full Text Available HTLV-1 is the causal agent of HTLV-1-associated myelopathy/tropical spastic paraparesis (HAM/TSP, a disease observed in up to 5% of individuals infected with HTLV-1. However, infected individuals without the disease can present neurological complaints relating to sensory, motor or urinary manifestations. The aim of this study was to investigate the incidence of neurological manifestations among patients with HTLV-1. Method HTLV-1 patients in Salvador, Bahia, Brazil, were enrolled into a cohort study. Results Among 414 subjects, 76 had definite and 87 had possible or probable HAM/TSP at the baseline, whereas 251 subjects had no neurological signs or symptoms. Definite HAM/TSP developed in 5 patients (1.74%. The asymptomatic subjects were selected for analysis. The incidence rate expressed per 1,000 persons-year was calculated. It was 206 for hand numbness, 129 for nocturia and 126 for urinary urgency. In the neurological examination, leg hyperreflexia presented an average incidence rate of 76; leg paraparesis, 52; and Babinski sign, 36. Kaplan-Meyer curves categorized according to gender and proviral load showed that females and patients with proviral load of more than 100,000 copies per 106 peripheral blood mononuclear cells (PBMCs presented higher risk. Conclusion Development of neurological symptoms or signs occurred in up to 30% of asymptomatic subjects during 8 years of follow-up. Female gender and high proviral load were risk factors for neurological disease.

    Endocrine disruptors such as phenolic compounds and parabens may be involved in chronic non-infective disease. While products incorporating these compounds are extensively utilized in consumer and personal products, little is known about their effect on bowel health. Inflammatory bowel disease (IBD) - consisting of the diseases ulcerative colitis and Crohn's disease - and irritable bowel syndrome are common chronic non-infectious diarrheal diseases. Despite limited knowledge on the etiology of IBD, these diseases have increased prevalence in industrialized countries and cause significant impairment to quality of life. In the present study we examine relationships between urinary environmental phenolic compounds, chronic diarrhea and inflammatory bowel disease. Data was obtained from the 2005–2010 US National Health and Nutrition Examination Survey (NHANES) including demographics, lifestyle factors, self-reported health conditions, inflammatory markers and urinary phenolic chemical concentrations. Only participants with complete environmental phenols & parabens component were included in our analysis. Chronic diarrheal symptoms were determined by using the 2009–2010 NHANES questionnaire which included questions pertaining to bowel health. We utilized chronic bowel leakage symptoms as a surrogate marker for chronic diarrhea. The presence of IBD was also analyzed from 2009 to 2010 NHANES data, as a sub-analysis for arthropathy directly querying the presence or absence of IBD. Among the subset of 5218 American adults aged 20–80 years in the NHANES study period who completed environmental phenols & parabens component, 25.5% reported chronic diarrheal symptoms. Abnormal markers of inflammation were present in 2200 (42.2%) of respondents. For IBD, 19 individuals with arthropathy confirmed a diagnosis of ulcerative colitis, and 1 person confirmed a Crohn's diagnosis.

    The metabolic syndrome is a cluster of common pathologies: abdominal obesity linked to an excess of visceral fat, insulin resistance, dyslipidemia and hypertension. At the molecular level, metabolic syndrome is accompanied not only by dysregulation in the expression of adipokines (cytokines and chemokines), but also by alterations in levels of leptin, a peptide hormone released by white adipose tissue. These changes modulate immune response and inflammation that lead to alterations in the hypothalamic 'bodyweight/appetite/satiety set point,' resulting in the initiation and development of metabolic syndrome. Metabolic syndrome is a risk factor for neurological disorders such as stroke, depression and Alzheimer's disease. The molecular mechanism underlying the mirror relationship between metabolic syndrome and neurological disorders is not fully understood. However, it is becoming increasingly evident that all cellular and biochemical alterations observed in metabolic syndrome like impairment of endothelial cell function, abnormality in essential fatty acid metabolism and alterations in lipid mediators along with abnormal insulin/leptin signaling may represent a pathological bridge between metabolic syndrome and neurological disorders such as stroke, Alzheimer's disease and depression. The purpose of this review is not only to describe the involvement of brain in the pathogenesis of metabolic syndrome, but also to link the pathogenesis of metabolic syndrome with neurochemical changes in stroke, Alzheimer's disease and depression to a wider audience of neuroscientists with the hope that this discussion will initiate more studies on the relationship between metabolic syndrome and neurological disorders. © Springer Basel AG 2011

  7. Neurologic long term outcome after drowning in children

    2012-08-01

    Full Text Available Abstract Drowning is a major source of mortality and morbidity in children worldwide. Neurocognitive outcome of children after drowning incidents cannot be accurately predicted in the early course of treatment. Therefore, aggressive out-of-hospital and in-hospital treatment is emphasized. There are "miracle" cases after long submersion times that have been reported in the medical literature, which mostly concern small children. However, many of the survivors will remain severely neurologically compromised after remarkably shorter submersion times and will consequently be a great burden to their family and society for the rest of their lives. The duration of submersion, the need of advanced life support at the site of the accident, the duration of cardiopulmonary resuscitation, whether spontaneous breathing and circulation are present on arrival at the emergency room are important factors related to survival with mild neurological deficits or intact function in drowned children. Data on long-term outcome are scarce. The used outcome measurement methods and the duration of follow-up have not been optimal in most of the existing studies. Proper neurological and neurophysiological examinations for drowned children are superior to outcome scales based chart reviews. There is evidence that gross neurological examination at the time of discharge from the hospital in young children does not reveal all the possible sequelae related to hypoxic brain injury and thus long-term follow-up of drowned resuscitated children is strongly recommended.

    To evaluate the effects of a government insurance programme covering tertiary care for the poor in Karnataka, India--Vajpayee Arogyashree Scheme (VAS)--on treatment seeking and postoperative outcomes. Geographic regression discontinuity. 572 villages in Karnataka, India. 3478 households in 300 villages where VAS was implemented and 3486 households in 272 neighbouring matched villages ineligible for VAS. A government insurance programme that provided free tertiary care to households below the poverty line in half of villages in Karnataka from February 2010 to August 2012. Seeking treatment for symptoms, posthospitalisation well-being, occurrence of infections during hospitalisation and need for rehospitalisation. The prevalence of symptoms was nearly identical for households in VAS-eligible villages compared with households in VAS-ineligible villages. However, households eligible for VAS were 4.96 percentage points (95% CI 1 to 8.9; p=0.014) more likely to seek treatment for their symptoms. The increase in treatment seeking was more pronounced for symptoms of cardiac conditions, the condition most frequently covered by VAS. Respondents from VAS-eligible villages reported greater improvements in well-being after a hospitalisation in all categories assessed and they were statistically significant in 3 of the 6 categories (walking ability, pain and anxiety). Respondents eligible for VAS were 9.4 percentage points less likely to report any infection after their hospitalisation (95% CI -20.2 to 1.4; p=0.087) and 16.5 percentage points less likely to have to be rehospitalised after the initial hospitalisation (95% CI -28.7 to -4.3; p<0.01). Insurance for tertiary care increased treatment seeking among eligible households. Moreover, insured patients experienced better posthospitalisation outcomes, suggesting better quality of care received. These results suggest that there are several pathways through which tertiary care insurance could improve health, aside from

    Children with social dysfunction and a first-degree relative with schizophrenia are at elevated risk for schizophrenia; however, the nature of this dysfunction is unclear. It was hypothesized that familial high-risk (HR) children and adolescents (n=17) would have social skill deficits relative to healthy controls (HC; n=35). HR participants had a bimodal distribution of social skill scores (47% excellent; 53% poor). HR participants had worse social skills, assertion and empathy scores, suggesting possible developmental precursors to the social amotivation domain of negative symptoms. Characterizing HR children's social deficits could assist identification of those at risk for schizophrenia. Copyright © 2014 Elsevier B.V. All rights reserved.

    Full Text Available Neurological soft signs (NSS comprise subtle deficits in sensory integration, motor coordination, and sequencing of complex motor acts which are typically observed in the majority of schizophrenia patients, including chronic cases and neuroleptic-naïve first-episode patients. However, recent studies clearly demonstrate that NSS are not a static feature of schizophrenia but vary in the clinical course of the disorder. This effect was investigated in a meta-analysis based on 17 longitudinal studies published between 1992 and 2012. Studies included between 10 and 93 patients with schizophrenia spectrum disorders (total number 787 with follow-up periods between 2 and 208 weeks. Beside the Neurological Examination Scale, the Cambridge Neurological Inventory and the Heidelberg NSS Scale were used to assess NSS. All but three studies found NSS to decrease in parallel with remission of psychopathological symptoms. This effect was more pronounced in patients with a remitting compared to a non-remitting, chronic course (Cohen´s d 0.81 vs. 0.15 and was significantly correlated with length of the follow-up period (r=-0.64 but not with age (r=0.28. NSS scores did not decrease to the level typically observed in healthy controls. From a clinical perspective, NSS may therefore be used to identify subjects at risk to develop schizophrenia and to monitor disease progression.

  13. The neurological legacy of John Russell Reynolds (1828-1896).

    2007-04-01

    Sir John Russell Reynolds was an eminent and highly influential physician in the Victorian era who held the Presidencies of the Royal College of Physicians of London, and of the British Medical Association. He was the protégée of the great experimental physiologist, Marshall Hall, who discovered the reflex arc, and succeeded to Hall's clinical practice in London. Reynolds' thought and clinical activities linked the emerging British neurology of the first half of the 19th century with its blossoming, particularly in London, from 1860 onwards. In his writings Reynolds was the first English author to apply the approach to classification of neurological disorders that is still often used, though now in modified form. He was also the first to enunciate the notion of positive and negative symptoms arising from neurological disease and to suggest their pathogenesis, and was arguably the originator of the influential concept that an idiopathic disease, epilepsy, existed, one to be distinguished from 'epileptiform' seizures due to brain pathology.

    The rapidly increasing elderly population poses a major challenge for future health-care systems. Neurological diseases in older persons are particularly common and coexist with other clinical conditions. This is not surprising given that, for example, even patients with Alzheimer Disease (AD) could have relevant extrapyramidal signs at the moment of the diagnosis with motor signs having more negative prognostic value. Longitudinal studies conducted on Parkinson Disease (PD) showed that, after 20 years, dementia is not only present in almost all survivors but is also the main factor influencing nursing home admission. Recently, it has been reported the importance of Comprehensive Geriatric Assessment (CGA: comprehensive evaluation of cognition, depressive symptoms, mobility and functional assessment) as a tool reducing morbidity in frail older patients admitted to any acute hospital unit. The CGA should be considered as a technological device, for physicians who take care of older persons affected by overlapping neurological diseases. CGA is an extraordinary and cost effective instrument even in patients with advanced neurological diseases where allows to collect valuable information for an effective plan of management.

    We explored the possibility that neurologic and neuropsychological changes constitute the earliest detectable manifestations of human immunodeficiency virus (HIV) infection. Without knowledge of HIV status, we assessed neurologic signs and symptoms and administered a battery of neuropsychological tests to 208 homosexual men, of whom 84 were HIV negative, 49 were HIV positive and asymptomatic, 29 were mildly symptomatic, and 46 had significant medical symptoms but not the acquired immunodeficiency syndrome. There was no difference between the HIV-negative and HIV-positive men in the frequency of neurologic signs or of defective or borderline performance on any neuropsychological test. However, HIV-positive men performed slightly but significantly worse than HIV-negative men on tests of verbal memory, executive function, and language. Similar results were obtained when comparisons were limited to HIV-positive medically asymptomatic and HIV-negative men. There was no degradation of neurologic status or neuropsychological performance across stages of HIV severity, but neurologic and neuropsychological summary scores correlated with CD4/CD8 ratios in the HIV-positive group. Ratings of neurologic signs and symptoms correlated with neuropsychological summary scores in the HIV-positive group only. Cognitive complaints were more frequent in the HIV-positive men; they correlated with actual test performance in the HIV-positive but not HIV-negative men. The constellation of subjective and objective neuropsychological and neurologic findings suggests the possibility of a definable syndrome associated with HIV infection in asymptomatic individuals.

    Full Text Available Creutzfeldt-Jakob disease (CJD is a rare, fatal neurodegenerative disease caused by an infectious protein called prion and is characterized by spongiform changes, neuronal loss, reactive astrocytic proliferation, and accumulation of pathologic cellular protein. Clinical presentation of CJD is characterized by rapidly progressive dementia, neurologic symptoms and visual impairment, and the development of akinetic mutism, which can mimic many neurological conditions. The diagnosis is based on clinical presentation, electroencephalogram, and typical cerebrospinal fluid and magnetic resonance imaging (MRI findings. Literature on the incidence and prevalence of CJD is lacking in South India. We report the case of a 57-year-old woman with progressive dementia and typical neurologic symptoms, myoclonic jerks, and MRI findings of CJD. This case highlights the need for a high index of suspicion to diagnose CJD.

    2014-10-01

    Homocysteine (Hcy) is a sulfur-containing amino acid that is generated during methionine metabolism. It has a physiologic role in DNA metabolism via methylation, a process governed by the presentation of folate, and vitamins B6 and B12. Physiologic Hcy levels are determined primarily by dietary intake and vitamin status. Elevated plasma levels of Hcy (eHcy) can be caused by deficiency of either vitamin B12 or folate, or a combination thereof. Certain genetic factors also cause eHcy, such as C667T substitution of the gene encoding methylenetetrahydrofolate reductase. eHcy has been observed in several medical conditions, such as cardiovascular disorders, atherosclerosis, myocardial infarction, stroke, minimal cognitive impairment, dementia, Parkinson's disease, multiple sclerosis, epilepsy, and eclampsia. There is evidence from laboratory and clinical studies that Hcy, and especially eHcy, exerts direct toxic effects on both the vascular and nervous systems. This article provides a review of the current literature on the possible roles of eHcy relevant to various neurologic disorders.

  16. Ketogenic diets, mitochondria, and neurological diseases

    Science.gov (United States)

    Gano, Lindsey B.; Patel, Manisha; Rho, Jong M.

    2014-01-01

    The ketogenic diet (KD) is a broad-spectrum therapy for medically intractable epilepsy and is receiving growing attention as a potential treatment for neurological disorders arising in part from bioenergetic dysregulation. The high-fat/low-carbohydrate “classic KD”, as well as dietary variations such as the medium-chain triglyceride diet, the modified Atkins diet, the low-glycemic index treatment, and caloric restriction, enhance cellular metabolic and mitochondrial function. Hence, the broad neuroprotective properties of such therapies may stem from improved cellular metabolism. Data from clinical and preclinical studies indicate that these diets restrict glycolysis and increase fatty acid oxidation, actions which result in ketosis, replenishment of the TCA cycle (i.e., anaplerosis), restoration of neurotransmitter and ion channel function, and enhanced mitochondrial respiration. Further, there is mounting evidence that the KD and its variants can impact key signaling pathways that evolved to sense the energetic state of the cell, and that help maintain cellular homeostasis. These pathways, which include PPARs, AMP-activated kinase, mammalian target of rapamycin, and the sirtuins, have all been recently implicated in the neuroprotective effects of the KD. Further research in this area may lead to future therapeutic strategies aimed at mimicking the pleiotropic neuroprotective effects of the KD. PMID:24847102

    Evidence suggests that many coeliac disease patients suffer from persistent clinical symptoms and reduced health-related quality of life despite a strict gluten-free diet. We aimed to find predictors for these continuous health concerns in long-term treated adult coeliac patients. In a nationwide study, 596 patients filled validated Gastrointestinal Symptom Rating Scale and Psychological General Well-Being questionnaires and were interviewed regarding demographic data, clinical presentation and treatment of coeliac disease, time and place of diagnosis and presence of coeliac disease-associated or other co-morbidities. Dietary adherence was assessed by a combination of self-reported adherence and serological tests. Odds ratios and 95% confidence intervals were calculated by binary logistic regression. Diagnosis at working age, long duration and severity of symptoms before diagnosis and presence of thyroidal disease, non-coeliac food intolerance or gastrointestinal co-morbidity increased the risk of persistent symptoms. Patients with extraintestinal presentation at diagnosis had fewer current symptoms than subjects with gastrointestinal manifestations. Impaired quality of life was seen in patients with long duration of symptoms before diagnosis and in those with psychiatric, neurologic or gastrointestinal co-morbidities. Patients with persistent symptoms were more likely to have reduced quality of life. There were a variety of factors predisposing to increased symptoms and impaired quality of life in coeliac disease. Based on our results, early diagnosis of the condition and consideration of co-morbidities may help in resolving long-lasting health problems in coeliac disease.

    2017-03-01

    The aim of this study was to evaluate whether the current state of child neurology education during pediatric residency provides adequate preparation for pediatric practice. A survey was sent to recent graduates from 3 pediatric residency programs to assess graduate experience, perceived level of competence, and desire for further education in child neurology. Responses from generalists versus subspecialists were compared. The response rate was 32%, half in general pediatric practice. Only 22% feel very confident in approaching patients with neurologic problems. This may represent the best-case scenario as graduates from these programs had required neurology experiences, whereas review of Accreditation Council of Graduate Medical Education-accredited residency curricula revealed that the majority of residencies do not. Pediatric neurologic problems are common, and pediatric residency graduates do encounter such problems in practice. The majority of pediatricians report some degree of confidence; however, some clear areas for improvement are apparent.

  19. Neurological Effects of Acute Carbon Monoxide Poisoning in Children

    2009-11-01

    Full Text Available Carbon monoxide poisoning (COP is one of the most common causes of mortality and morbidity due to poisoning in all over the world. Although the incidence of COP has not been known exactly in the childhood, almost one-third of CO exposures occurred in children. The data regarding COP in children are inconclusive. Children may be more vulnerable to CO exposure than adults as a result of their high respiration and metabolic rates, high oxygen metabolism, and immature central nervous system. Recent researches proposed new theories about neurological effects of CO toxicity. The clinical presentations associated acute COP may be various and nonspecific. Unrecognized CO exposure may lead to significant morbidity and mortality. CO exposed children often become symptomatic earlier, and recover more rapidly, than similarly CO exposed adults. Mild clinical signs and symptoms associated with COP are headache, dizziness, weakness, lethargy, and myalgia; however, severe signs and symptoms such as blurred vision, syncope, convulsion, coma, cardiopulmonary arrest and death can also accompany with COP. Neurologic manifestations can include altered mental status at different degrees, neck stiffness, tremor, ataxia, and positive Babinski's sign. Delayed neurologic sequels (DNS of COP might be seen in children like adults. DNS symptoms and signs in children include memory problems, mental retardation, mutism, fecal and urinary incontinence, motor deficits, facial palsy, psychosis, chronic headache, seizures, and epilepsy. After CO exposure children must be cared to detect and treat DNS. Although hyperbaric oxygen therapy (HBOT is reported to prevent development of DNS, its indications, application duration and procedures are controversial in both of the children and adults. Although their predictive values are limited, exposing to CO more than eight hours and suffering from CO-induced coma, cardiac arrest, lactic acidosis, high COHb levels, and pathologic findings

  20. A new perspective on delusional states: Evidence for claustrum involvement

    Cristina Maria Patru

    2015-11-01

    Full Text Available Delusions are a hallmark positive symptom of schizophrenia, although they are also associated with a wide variety of other psychiatric and neurological disorders. The heterogeneity of clinical presentation and underlying disease, along with a lack of experimental animal models, make delusions exceptionally difficult to study in isolation, either in schizophrenia or other diseases. To date, no detailed studies have focused specifically on the neural mechanisms of delusion, although some studies have reported characteristic activation of specific brain areas or networks associated with them. Here we present a novel hypothesis and extant supporting evidence implicating the claustrum, a relatively poorly understood forebrain nucleus, as a potential common center for delusional states.

    Feinsod, Moshe

    2010-01-01

    The Bible, a major pillar of Western Civilization consists of Hebrew Scriptures, assembled over a millennium and accepted as of divine origin. The Talmud is a compendium of Jewish laws, covering every possible aspect of life, analyzed in depth from 200 BCE to 600 CE, becoming the foundation of Jewish existence. The all-encompassing character of the books provides numerous medical problems and observations that appear in various connotations. When in need to clarify various legal dilemmas, the Talmudic sages displayed astoundingly accurate anatomical knowledge and were pioneers in clinical-pathological correlations. The descriptions of "neurological" events in the Bible are very precise but show no evidence of neurological knowledge. Those reported in the various tractates of the Talmud are evidence of a substantial medical knowledge, marked by Hellenistic influence. Subjects such as head and spinal injuries, epilepsy, handedness neuralgias aphasia tinnitus and tremor were discussed in depth. This chapter is an updated collection of the studies, extracting observations and discussions of neurological manifestations from the ancient texts.

  2. Complementary and alternative medicine in chronic neurological pain

    Directory of Open Access Journals (Sweden)

    Shri Kant Mishra

    2015-01-01

    Full Text Available Background: There is a growing trend towards opting for complementary and alternative medicine (CAM in the therapeutic management of various medical disorders. We try to evaluate the current recommendations for CAM therapies in key neurological disorders. Materials and Methods: Sources like PubMed, Embase, UCLA libraries, USC libraries, and National Center for Complementary and Alternative Medicine (NCCAM books were searched to gather data for this review. Results: We discuss the current recommendations for CAM therapies in headaches, neck pains, lower back pains, neuropathic pains, and cancer-related pains. The CAM therapies discussed include natural therapies, mind and body therapies, and several other modalities. Conclusion: We conclude that in spite of vast literature available on the CAM therapies for neurological disorders; there is little evidence for the most beneficial CAM remedies that target common neurological disorders. Although new CAM modalities are brought to light in addition to those that have existed for centuries, further scientific data from evidence-based studies is needed to accurately compare the CAM therapies amongst each other and allopathic treatments.

    We aimed to investigate anxiety level of caregivers of neurological patients with dysphagia, and the relationship of patient-related factors to anxiety level of dysphagia caregivers. A total of 103 adult neurological patients with dysphagia (study group), 30 without dysphagia (control group), and their primary caregivers were included. Types of feeding, condition of dependency in eating and drinking, dysphagia duration, and history of previous dysphagia treatment were recorded for study group. In study group, the Turkish version of the Eating Assessment Tool-10 (T-EAT-10) was used to determine dysphagia symptom severity. Penetration and aspiration severity was determined with the penetration-aspiration scale (PAS). The Spielberger State-Trait Anxiety Inventory (STAI) that has two subscales including state anxiety (S-STAI) and trait anxiety (T-STAI) was used to determine anxiety level of caregivers. There was no difference between groups in terms of age, gender, weight, and height. The mean S-STAI was 42.56 ± 10.10 for the study group and 29.20 ± 6.64 for the control group (p dysphagia treatment (p = 0.01, r = 0.25). No correlation was found between STAI (in terms of both S-STAI and T-STAI) and T-EAT-10, PAS, types of feeding, condition of dependency in eating and drinking, dysphagia duration (p > 0.05). Caregivers of neurological patients with dysphagia have greater anxiety level than caregivers of neurological patients without dysphagia.

  4. [Neurological evaluation of the leper king Baldwin IV of Jerusalem].

    Science.gov (United States)

    Guerrero-Peral, A L

    In the medieval period, physicians became more aware of leprosy symptoms and differentiated it from other similar diseases. Baldwin, the leper king of Jerusalem (1161-1185), probably contributed to an increasing interest and tolerance to this disease in medieval Christian states. We review historical descriptions of the neurological manifestations he developed. William of Tyre gives us a description of first symptoms experienced by the prince when aged nine. He notices that half of his right arm and hand were partially numb. No skin or nervous lesions are described. By his early twenties, muscle weakness makes him unable to walk. He gets blinded, probably due to keratopathy related to facial nerves involvement. Repeated attacks of fever lead to progressive worsening of his disease. He finally dies in Jerusalem, aged twenty-five, probably due to a septicaemia from infected sores. The earliest sign of Baldwin's disease is anaesthesia. Though skin lesions are not described, it is likely that at this point he had a tuberculoid form of leprosy. As his disease finally takes a lepromatous form, we suspect that it began as a borderline, immunologically unstable form. Leper king Baldwin biography gives us interesting descriptions of neurological clinical features of leprosy. Besides, it helps us to discover twelfth century medicine knowledge about this disease.

    Women who carry fragile X mental retardation 1 (FMR1)gene premutation expansions frequently report neurological or endocrine symptoms and prior studies have predominantly focused on questionnaire report of medical issues. Premutation carrier (PMC) women (n = 33) and non-carrier controls (n = 13) were recruited and evaluated by a neurologist, neuropsychologist, and endocrinologist. Blood and skin biopsies were collected for molecular measures. Scales for movement disorders, neuropathy, cognitive function, psychiatric symptoms, sleep, and quality of life were completed. The average age of the women was 51 years (n = 46) and average CGG repeat size was 91 ± 24.9 in the FMR1 PMC women. Seventy percent of the PMC women had an abnormal neurological examination. PMC women had significantly higher scores on the Fragile X-Associated Tremor Ataxia Syn
