Sample records for acute paranoid psychosis

  1. Manganese and acute paranoid psychosis: a case report

    Egger Jos I

    2011-04-01

    Full Text Available Abstract Introduction Manganese regulates many enzymes and is essential for normal development and body function. Chronic manganese intoxication has an insidious and progressive course and usually starts with complaints of headache, fatigue, sleep disturbances, irritability and emotional instability. Later, several organ systems may be affected and, due to neurotoxicity, an atypical parkinsonian syndrome may emerge. With regard to neuropsychiatry, an array of symptoms may develop up to 30 years after intoxication, of which gait and speech abnormalities, cognitive and motor slowing, mood changes and hallucinations are the most common. Psychotic phenomena are rarely reported. Case presentation We describe the case of a 49-year-old Caucasian man working as a welder who was referred to our facility for evaluation of acute paranoid psychotic behavior. Our patient's medical history made no mention of any somatic complaints or psychiatric symptoms, and he had been involved in a professional career as a metalworker. On magnetic resonance imaging scanning of his brain, a bilateral hyperdensity of the globus pallidus, suggestive for manganese intoxication, was found. His manganese serum level was 52 to 97 nmol/L (range: 7 to 20 nmol/L. A diagnosis of organic psychotic disorder due to manganese overexposure was made. His psychotic symptoms disappeared within two weeks of treatment with low-dose risperidone. At three months later, serum manganese was decreased to slightly elevated levels and the magnetic resonance imaging T1 signal intensity was reduced. No signs of Parkinsonism were found and a definite diagnosis of manganese-induced apathy syndrome was made. Conclusion Although neuropsychiatric and neurological symptoms caused by (chronic manganese exposure have been reported frequently in the past, in the present day the disorder is rarely diagnosed. In this report we stress that manganese intoxication can still occur, in our case in a confined

  2. Acute paranoid psychosis as sole clinical presentation of hepatic artery thrombosis after living donor liver transplantation

    Obed Aiman

    2010-02-01

    Full Text Available Abstract Background Hepatic artery thrombosis is a devastating complication after orthotopic liver transplantation often requiring revascularization or re-transplantation. It is associated with considerably increased morbidity and mortality. Acute cognitive dysfunction such as delirium or acute psychosis may occur after major surgery and may be associated with the advent of surgical complications. Case presentation Here we describe a case of hepatic artery thrombosis after living-donor liver transplantation which was not preceded by signs of liver failure but rather by an episode of acute psychosis. After re-transplantation the patient recovered without sequelae. Conclusion This case highlights the need to remain cautious when psychiatric disorders occur in patients after liver transplantation. The diagnostic procedures should not be restricted to medical or neurological causes of psychosis alone but should also focus vascular complications related to orthotopic liver transplantation.

    Aim. To investigate the efficacy of carbamazepine as adjuvant drug therapy in acute paranoid psychosis with associated EEG abnormalities, compared to sole antipsychotic treatment. Methods. Eleven medication-naive patients diagnosed with acute paranoid psychosis with associated EEG abnormalities were divided into two treatment groups: sole fluphenazine group, with flexible dosing of 5-10 mg/day (n=6), and carbamazepine group (n=5) with the addition of carbamazepine (600 mg/day) to fluphenazine...

    Full Text Available Aim. To investigate the efficacy of carbamazepine as adjuvant drug therapy in acute paranoid psychosis with associated EEG abnormalities, compared to sole antipsychotic treatment. Methods. Eleven medication-naive patients diagnosed with acute paranoid psychosis with associated EEG abnormalities were divided into two treatment groups: sole fluphenazine group, with flexible dosing of 5-10 mg/day (n=6, and carbamazepine group (n=5 with the addition of carbamazepine (600 mg/day to fluphenazine treatment. Clinical Global Impression (CGI, Brief Psychiatric Rating Scale (BPRS, Scale for the Assessment of Negative Symptoms (SANS, and EEG were assessed on the baseline and after 6 weeks of treatment. Paired and two-tailed t-tests were used for statistical significance. Results. All the patients showed significant improvement of mental state after 6 weeks of treatment with no significant differences in CGI, BPRS, and total SANS scores in relation to the therapy with carbamazepine. Nevertheless, after 6 weeks of the treatment, EEG findings were significantly better in carbamazepine group, in relation to the findings from the onset of the treatment, as well as in comparison to sole fluphenazine group. Conclusion. Although carbamazepine stabilized abnormal brain electrical activities it seemed that the associated EEG abnormalities were not significant for acute psychosis observed. These preliminary results suggested that there was no convincing evidence that carbamazepine was efficient as the augmentation of antipsychotic treatment for patients with both acute paranoid psychosis and EEG abnormalities.

  8. Psychosis with paranoid delusions after a therapeutic dose of mefloquine: a case report

    Browning Joseph

    2006-08-01

    Full Text Available Abstract Background Convenient once-a-week dosing has made mefloquine a popular choice as malaria prophylaxis for travel to countries with chloroquine-resistant malaria. However, the increased use of mefloquine over the past decade has resulted in reports of rare, but severe, neuropsychiatric adverse reactions, such as anxiety, depression, hallucinations and psychosis. A direct causality between mefloquine and severe reactions among travelers has been partly confounded by factors associated with foreign travel and, in the case of therapeutic doses of mefloquine, the central nervous system manifestations of Plasmodium infection itself. The present case provides a unique natural history of mefloquine-induced neuropsychiatric toxicity and revisits its dose-dependent nature. Case presentation This report describes an acute exacerbation of neuropsychiatric symptoms after an unwarranted therapeutic dose (1250 mg of mefloquine in a 37-year-old male previously on a once-a-week prophylactic regimen. Neuropsychiatric symptoms began as dizziness and insomnia of several days duration, which was followed by one week of escalating anxiety and subtle alterations in behaviour. The patient's anxiety culminated into a panic episode with profound sympathetic activation. One week later, he was hospitalized after developing frank psychosis with psychomotor agitation and paranoid delusions. His psychosis remitted with low-dose quetiapine. Conclusion This report suggests that an overt mefloquine-induced psychosis can be preceded by a prodromal phase of moderate symptoms such as dizziness, insomnia, and generalized anxiety. It is important that physicians advise patients taking mefloquine prophylaxis and their relatives to recognize such symptoms, especially when they are accompanied by abrupt, but subtle, changes in behaviour. Patients with a history of psychiatric illness, however minor, may be at increased risk for a mefloquine-induced neuropsychiatric toxicity

    Rajnish Raj; Raj Kumar

    2014-01-01

    Topiramate (TPM) is a new potent antiepileptic drug (AED) used as add-on therapy for generalized and partial seizures that are resistant to the other AEDs; or as a mood stabilizer, and for reducing weight gain associated with olanzapine and clozapine in patients with bipolar disorder or schizophrenia. However, there is a higher risk of psychosis with TPM in patients with a past history of psychiatric disorder. This case report highlights emergence of psychosis that was related to TPM which re...

    2016-07-01

    Background Measuring patient satisfaction in mental health care potentially provides valuable information, but studies in acutely admitted psychosis patients are scarce. Aims The aims were to assess satisfaction among patients acutely admitted with psychosis, to compare satisfaction in voluntarily versus involuntarily admitted patients, and to assess the influence of symptom load and insight. Methods The UKU Consumer Satisfaction Rating Scale (UKU-ConSat) was used. A total of 104 patients completed the UKU-ConSat at discharge/follow-up (between 6-11 weeks after admittance if not discharged earlier) (mean duration of stay 4 weeks), thus corresponding to the end of the acute treatment phase. Results A total of 88.4% had total scores above zero (satisfied). Only three of the eight single items were statistically significantly different among patients admitted voluntarily versus involuntarily, and only the information item score remained significantly different in adjusted analyses. Insight level at admittance, and an increasing level of insight during the acute phase were positively associated with patient satisfaction, whereas levels and changes in positive and negative psychosis symptoms were indirectly related to satisfaction via this process of insight. Conclusions The vast majority of the acutely admitted patients were satisfied with treatment. There were few differences between the involuntarily and voluntarily admitted patient groups, except that the involuntary care group was clearly less satisfied with the information provided. Poor insight had a major negative impact on treatment satisfaction in psychosis. The provision of sufficient and adequate information is an important target for mental health care service improvement. PMID:26750532

    Full Text Available Primary hyperparathyroidism (PHPT is a disorder of calcium homeostasis. We report the case of a 17-year-old adolescent male, who presented with an acute psychosis coinciding with severe hypercalcemia and markedly elevated intact parathyroid hormone (iPTH level and low vitamin D level. A Sestamibi scan showed a positive signal inferior to the left lobe of the thyroid gland. He had only a partial response to the initial medical and psychiatric management. The enlarged parathyroid gland was resected surgically and postoperatively serum calcium and iPTH levels normalized. The histopathology was compatible with a benign adenoma. Patient’s acute psychotic symptoms resolved gradually after surgery; however he remained under psychiatric care for the behavioral issues for about 6 months after surgery. While psychosis is a rare clinical manifestation of hypercalcemia secondary to PHPT in pediatric population, it should be considered as a clinical clue in an otherwise asymptomatic pediatric patient.

    Full Text Available We report the case of an old man treated with methylprednisolone for chronic lymphoid leukemia. After two months of treatment, he declared an acute steroid psychosis and beat his wife to death. Steroids were stopped and the psychotic symptoms subsided, but his condition declined very quickly. The clinical course was complicated by a major depressive disorder with suicidal ideas, due to the steroid stoppage, the leukemia progressed, and by a sudden onset of a fatal pulmonary embolism. This clinical case highlights the importance of early detection of steroid psychosis and proposes, should treatment not be stopped, a strategy of dose reduction combined with a mood stabilizer or antipsychotic treatment. In addition have been revised the risks of the adverse psychiatric effects of steroids.

  7. Acute Psychosis and Type 2 Diabetes Mellitus:Should Screening Guidelines Be Revised?

    Bauer, Leah K.; Wulsin, Lawson R.; Guadagno, Gina

    2011-01-01

    Although psychosis increases the risk for developing type 2 diabetes, the temporal relationship between the onset of psychosis and the onset of diabetes has not been studied. We present 6 cases of acute psychosis, which led to the new diagnosis of type 2 diabetes during inpatient psychiatric admission within days to weeks of the psychotic episode. The implications of these findings and the efficacy of current diabetes screening guidelines are discussed.

  10. Acute Psychosis as Major Clinical Presentation of Legionnaires’ Disease

    Ricardo Coentre

    2016-01-01

    Full Text Available We report a case of a 61-year-old woman who presented with acute psychosis as a major manifestation of Legionnaires’ disease in the absence of other neuropsychiatric symptoms. Clinical history revealed dry cough and nausea. Observation showed fever and auscultation crackles in the lower lobe of the right lung. Laboratory testing demonstrated elevated C-reactive protein and lung chest radiograph showed patchy peribronchial and right lower lobe consolidation. Soon after admission, she started producing purulent sputum. Epidemiological data suggested Legionella pneumophila as possible cause of the clinical picture that was confirmed by urinary antigen detection and polymerase chain reaction of the sputum. She was treated with levofloxacin 750 mg/day for 10 days with complete remission of pulmonary and psychiatric symptoms. She has not had further psychotic symptoms.

  11. [Categorical and dimensional diagnostic approach to acute psychosis in view of operational diagnostic criteria].

    Sakamoto, Kaoru

    2011-01-01

    "Acute psychosis" is the tentative diagnosis made for the patients presenting acute onset of delusion, hallucination, confusion and emotional instability. "Acute psychosis" was focused in view of operational diagnostic criteria, ie, DSM-IV-TR and ICD-10. The diagnostic categories in the DSM-IV-TR corresponding to "acute psychosis" were brief psychotic disorder, schizophreniform disorder, schizo-affective disorder and mood disorder with psychotic features. Although brief psychotic disorder is representative of "acute psychosis" in the DSM-TR, it lacks in clinical usefulness, because its diagnostic criteria, based on no historical background, lack clinical validity in terms of symptom definition and duration (1 month>). On the other hand, in the ICD-10, a diagnostic category of acute transient psychotic disorder was based on the traditional "acute psychosis" concept that has been bred in the European Psychiatry. Among the acute transient psychotic disorders, acute polymorphic psychotic disorder is the diagnostic category made according to traditional concept of "bouffées délirantes" and cycloid psychosis. It is a clinically useful diagnostic category, because it could predict favorable episode outcome, if a person with fairly good premorbid social adaptation presents acute onset of polymorphic psychotic symptoms. One of the most prominent points of the revision of DSM-IV-TR to DSM-5 is the adoption of dimensional approach evaluation (diagnosis) in a disorder-crossing fashion. In addition to insomnia, depressive mood and anxiety, symptomatic domain such as acute onset, bipolarity, polymorphism of psychotic symptoms, and furthermore such domain as premorbid social adaptation, life event and episode outcome should be evaluated in the course of treatment, contributing to the clinical practice of the patients with acute psychosis.

    We present the case of a 45-year-old female patient who developed an acute polymorphic psychosis after treatment with the antibiotic ciprofloxacin. The patient showed a distinct neuropsychological deficit of the executive function. Comparing the psychopharmacological features of ketamine and ciprofloxacine we hypothesize that ciprofloxacine leads to psychosis similar to a ketamine induced psychosis. Our case report is unique not only because fluorquinolone induced psychosis has a very low ...

  14. Acute psychosis in children: do not miss immune-mediated causes.

    AlHakeem, Afnan S; Mekki, Mohamed S; AlShahwan, Saad M; Tabarki, Brahim M

    2016-07-01

    New-onset psychosis in children represents a complex presenting symptom. Psychosis can be attributable to a combination of factors and etiologies, and all possible causes must be systematically examined. There is growing evidence that a proportion of psychosis/ psychiatric manifestations in children may be immunemediated, and physicians should consider this etiology in each presentation of first-episode psychosis. Immunemediated encephalopathies/encephalitis are increasingly being recognized in children with antibodies to N-methyl-D-aspartate receptor, Leucine-rich gliomainactivated 1 or other central nervous system antigens such as Contactin-associated protein-like 2, glutamic acid decarboxylase, alpha-amino-3-hydroxy-5-methyl-4isoxazolepropionic acid or Gamma-aminobutyric acid B. In this study, we describe 3 cases of immune-mediated encephalopathy/encephalitis with prominent psychiatric symptoms at presentation, and suggest a practical diagnostic and treatment approach for children with acute psychosis of an immune-mediated cause.

  18. Fronto-limbic novelty processing in acute psychosis: disrupted relationship with memory performance and potential implications for delusions

    Björn H Schott

    2015-06-01

    Full Text Available Recent concepts have highlighted the role of the hippocampus and adjacent medial temporal lobe (MTL in positive symptoms like delusions in schizophrenia. In healthy individuals, the MTL is critically involved in the detection and encoding of novel information. Here, we aimed to investigate whether dysfunctional novelty processing by the MTL might constitute a potential neural mechanism contributing to the pathophysiology of delusions, using functional magnetic resonance imaging (fMRI in 16 unmedicated patients with paranoid schizophrenia and 20 age-matched healthy controls. All patients experienced positive symptoms at time of participation. Participants performed a visual target detection task with complex scene stimuli in which novel and familiar rare stimuli were presented randomly intermixed with a standard and a target picture. Presentation of novel relative to familiar images was associated with hippocampal activation in both patients and healthy controls, but only healthy controls showed a positive relationship between novelty-related hippocampal activation and recognition memory performance after 24 hours. Patients, but not controls, showed a robust neural response in the orbitofrontal cortex (OFC during presentation of novel stimuli. Functional connectivity analysis in the patients further revealed a novelty-related increase of functional connectivity of both the hippocampus and the OFC with the rostral anterior cingulate cortex (rACC and the ventral striatum. Notably, delusions correlated positively with the difference of the functional connectivity of the hippocampus versus the OFC with the rACC. Taken together, our results suggest that alterations of fronto-limbic novelty processing may contribute to the pathophysiology of delusions in patients with acute psychosis.

    Introduction Hypothyroidism is one of the most important causes of treatable dementia, and psychosis occasionally associated with it is known as myxedema madness. We report a case of a 90-year-old patient who developed myxedema madness acutely without overt clinical symptoms and signs suggestive of hypothyroidism. Case presentation A 90-year-old Japanese man, a general practitioner, was admitted to our emergency room because of acute-onset lethargy, delusions, and hallucinations. He had been ...

    2014-01-01

    Levetiracetam (LEV) is a relatively newer antiepileptic drug with novel mechanism of action. It was introduced to the market in the year 2000. Pre-marketing clinical trials of the drug reported good tolerability with a wide safety margin. On post-marketing updates, there are few reports of psychosis after treatment with the drug. Here, we report a case of 52-year-old epileptic man who developed acute, reversible psychosis within 3 days of initiation of treatment. The drug was prescribed at a ...

  5. Markers of thrombogenesis are activated in unmedicated patients with acute psychosis: a matched case control study

    2011-01-01

    Full Text Available Abstract Background Antipsychotic treatment has been repeatedly found to be associated with an increased risk for venous thromboembolism in schizophrenia. The extent to which the propensity for venous thromboembolism is linked to antipsychotic medication alone or psychosis itself is unclear. The objective of this study was to determine whether markers of thrombogenesis are increased in psychotic patients who have not yet been treated with antipsychotic medication. Methods We investigated the plasma levels of markers indicating activation of coagulation (D-dimers and Factor VIII and platelets (soluble P-selectin, sP-selectin in an antipsychotic-naive group of fourteen men and eleven women with acute psychosis (age 29.1 ± 8.3 years, body mass index 23.6 ± 4.7, and twenty-five healthy volunteers were matched for age, gender and body mass index. Results D-dimers (median 0.38 versus 0.19 mg/l, mean 1.12 ± 2.38 versus 0.28 ± 0.3 mg/l; P = 0.003 and sP-selectin (median 204.1 versus 112.4 ng/ml, mean 209.9 ± 124 versus 124.1 ± 32; P = 0.0005 plasma levels were significantly increased in the group of patients with acute psychosis as compared with healthy volunteers. We found a trend (median 148% versus 110%, mean 160 ± 72.5 versus 123 ± 62.5; P = 0.062 of increased plasma levels of factor VIII in psychotic patients as compared with healthy volunteers. Conclusions The results suggest that at least a part of venous thromboembolic events in patients with acute psychosis may be induced by pathogenic mechanisms related to psychosis rather than by antipsychotic treatment. Finding an exact cause for venous thromboembolism in psychotic patients is necessary for its effective treatment and prevention.

    1980-01-01

    Haloperidol (Haldol) is useful in the management of acutely psychotic patients who present with excited behavior which threatens their safety and the safety of others. The use of haloperidol allows rapid control of psychotic behavior with minimal risk of hypotension and avoidance of the excessive sedation associated with other antipsychotics. This article summarizes the rationale, indications, goals and treatment techniques of rapid treatment with intramuscular haloperidol. Major side effects...

  12. Acute Psychosis Associated with Subcortical Stroke: Comparison between Basal Ganglia and Mid-Brain Lesions

    Aaron McMurtray

    2014-01-01

    Full Text Available Acute onset of psychosis in an older or elderly individual without history of previous psychiatric disorders should prompt a thorough workup for neurologic causes of psychiatric symptoms. This report compares and contrasts clinical features of new onset of psychotic symptoms between two patients, one with an acute basal ganglia hemorrhagic stroke and another with an acute mid-brain ischemic stroke. Delusions and hallucinations due to basal ganglia lesions are theorized to develop as a result of frontal lobe dysfunction causing impairment of reality checking pathways in the brain, while visual hallucinations due to mid-brain lesions are theorized to develop due to dysregulation of inhibitory control of the ponto-geniculate-occipital system. Psychotic symptoms occurring due to stroke demonstrate varied clinical characteristics that depend on the location of the stroke within the brain. Treatment with antipsychotic medications may provide symptomatic relief.

    2012-07-01

    Full Text Available Abstract Introduction Anti-N-methyl-D-aspartate receptor (anti-NMDAR encephalitis is a rare, newly defined autoimmune clinical entity that presents with atypical clinical manifestations. Most patients with anti-N-methyl-D-aspartate receptor encephalitis develop a progressive illness from psychosis into a state of unresponsiveness, with catatonic features often associated with abnormal movements and autonomic instability. This is the first report of anti-N-methyl-D-aspartate receptor encephalitis in a Greek pediatric hospital. Case presentation An 11-year-old Greek girl presented with clinical manifestations of acute psychosis. The differential diagnosis included viral encephalitis. The presence of a tumor usually an ovarian teratoma, a common clinical finding in many patients, was excluded. Early diagnosis and prompt immunotherapy resulted in full recovery up to one year after the initial diagnosis. Conclusion Acute psychosis is a rare psychiatric presentation in children, diagnosed only after possible organic syndromes that mimic acute psychosis are excluded, including anti-N-methyl-D-aspartate receptor receptor encephalitis. Pediatricians, neurologists and psychiatrists should consider this rare clinical syndrome, in order to make an early diagnosis and instigate appropriate treatment to maximize neurological recovery.

  14. Does amantadine induce acute psychosis? A case report and literature review

    Xu, Wei-juan; Wei, Ning; Xu, Yi; Hu, Shao-hua

    2016-01-01

    Background Over-the-counter cold medicines, which contain amantadine, are widely used in the People’s Republic of China. Clinicians are familiar with the psychosis caused by long-term treatment with amantadine, especially in elderly patients; however, early-onset psychotic complications among healthy young individuals have rarely been reported. Case presentation This article reports the case of a 28-year-old patient who presented with hallucination–delusion syndrome soon after treatment with cold medicine containing amantadine hydrochloride and acetaminophen. The symptoms resolved completely after a 2-week course of paliperidone treatment. Conclusion Clinicians should be sensitive to the acute psychotic complications induced by an interaction between amantadine and acetaminophen. PMID:27103808

  15. Spinocerebellar ataxia-10 with paranoid schizophrenia

    2015-01-01

    Full Text Available Spino-cerebellar ataxia type 10 (SCA10 is an autosomal dominant disorder that is characterized by cerebellar ataxia, seizures and nystagmus with a fragmented pursuit. Schizophrenia has been reported with SCAs 1 and 2 yet in SCA 10, psychiatric manifestations are uncommon. We report a Hispanic family involving a father and his four children with SCA10 genetic mutation. Two of his children, a 20-year-old female and a 23-year-old male, presented with gradually progressive spino-cerebellar ataxia and paranoid schizophrenia. Neurological examination revealed ocular dysmetria, dysdiadokinesia, impaired finger-to-nose exam, gait ataxia and hyperreflexia in both the cases. Additionally, they had a history of psychosis with destructive behavior, depression and paranoid delusions with auditory hallucinations. Serology and CSF studies were unremarkable and MRI brain revealed cerebellar volume loss. Ultimately, a test for ATAXIN-10 mutation was positive thus confirming the diagnosis of SCA10 in father and his four children. We now endeavor to investigate the association between schizophrenia and SCA10.

  16. Attributional style in fist episode of schizophrenia and schizophrenia spectrum disorders with and without paranoid ideation.

    Zaytseva, Yulia; Burova, Vitalina; Garakh, Zanna; Gurovich, Isaac Ya

    2013-09-01

    In the present study we evaluated attributional style which refers to how individuals explain the causes for positive and negative events in their lives in patients with first episode of schizophrenia with and without paranoid ideation. 43 patients with first episode of psychosis and 37 matched normal controls completed Ambiguous Intentions Hostility Questionnaire (AIHQ) (Combs et al. 2007). Between group comparison of AIHQ scores showed a notable tendency to show aggressive response in overall patients group. We obtained significant elevation of hostility and blame biases scores in intentional and accidental situations in patients with paranoid ideation while the patients with non-paranoid ideation showed greater hostility and blame biases only in accidental situations as compared to controls. Correlations with positive and negative symptoms were obtained. Our findings suggest that patients with first episode of psychosis exhibit difficulties of the attribution biases which are interconnected with symptoms and thus indicate a trait-deficit of attributional style.

    Illicit drug use may influence cognition in non-affective psychosis. Previous studies have shown better cognition in psychosis with illicit drug use as compared to psychosis only. Possibly, illicit drug using patients have more transient drug-related cognitive deficits. Thus, the aim of the present study was to examine cognitive change the first weeks after admission to a psychiatric emergency ward, expecting more cognitive improvement at follow-up in the illicit drug group as compared to psy...

  1. Exploring psychotic symptoms: a comparison of motor related neuronal activation during and after acute psychosis

    Sheridan Rains Luke

    2012-08-01

    Full Text Available Abstract Background Delusions and hallucinations are classic positive symptoms of schizophrenia. A contemporary cognitive theory called the ‘forward output model’ suggests that the misattribution of self-generated actions may underlie some of these types of symptoms, such as delusions of control – the experience of self-generated action being controlled by an external agency. In order to examine the validity of this suggestion, we performed a longitudinal functional magnetic resonance imaging (fMRI study examining neuronal activation associated with motor movement during acute psychosis. Methods We studied brain activation using fMRI during a motor task in 11 patients with schizophrenia and 9 healthy controls. The patient group was tested at two time points separated by 6–8 weeks. Results At initial testing, the patient group had a mean Positive and Negative Syndrome Scale score of 56.3, and showed significantly increased activation within the left inferior parietal lobe (IPL compared to controls. Patients reported significantly decreased positive symptoms at 6–8 week followup and IPL activation had returned to normal. Our results demonstrate that first-rank positive symptoms are associated with hyperactivation in the secondary somatosensory cortex (IPL. Conclusions These findings lend further credence to the theory that a dysfunction in the sensory feedback system located in the IPL, and which is thought to underlie our sense of agency, may contribute to the aetiology of delusions of control.

  3. Paranoid Ideation and Violence: Meta-analysis of Individual Subject Data of 7 Population Surveys

    Coid, Jeremy W.; Ullrich, Simone; Bebbington, Paul; Fazel, Seena; Keers, Robert

    2016-01-01

    There is controversy whether associations between psychosis and violence are due to coexisting substance misuse and factors increasing risk in nonpsychotic persons. Recent studies in clinical samples have implicated independent effects of paranoid delusions. Research findings suggest that individual psychotic-like-experiences on the psychosis continuum in the general population are associated with violence; it remains unclear whether this association is due to psychiatric comorbidity. We pooled data from 7 UK general population surveys (n = 23 444) and conducted a meta-analysis of individual subject data. Further meta-analyses were performed to identify heterogeneity. Main exposure variables: 5 psychotic-like-experiences and a categorical measure of psychosis. Comorbidity was established through standardized self-report instruments. Information was collected on violence, severity, victims. Paranoid ideation was associated with violence (AOR 2.26, 95% CI 1.75–2.91), severity and frequency, even when controlling for effects of other psychotic-like-experiences. Associations were not explained by comorbid conditions, including substance dependence. Psychotic disorder was associated with violence and injury to the perpetrator but associations were explained by paranoid ideation. Individual associations between hypomania, thought insertion, hallucinations, and violence were nonsignificant after adjustments, and significantly associated only when comorbid with antisocial personality disorder. Strange experiences were only associated with intimate partner violence. Paranoid ideation on a psychosis-continuum in the general population was associated with violence. All other associations were explained by comorbidity. Further investigation should determine whether paranoid ideation among persons in the community require preventive interventions, similar to those presenting to mental health services. Nevertheless, risks are considerably increased for psychotic

    Full Text Available Abstract Background Cannabis is the most commonly used illegal drug and its therapeutic aspects have a growing interest. Short-term psychotic reactions have been described but not clearly with synthetic oral THC, especially in occasional users. Case presentations We report two cases of healthy subjects who were occasional but regular cannabis users without psychiatric history who developed transient psychotic symptoms (depersonalization, paranoid feelings and derealisation following oral administration of cannabis. In contrast to most other case reports where circumstances and blood concentrations are unknown, the two cases reported here happened under experimental conditions with all subjects negative for cannabis, opiates, amphetamines, cocaine, benzodiazepines and alcohol, and therefore the ingested dose, the time-events of effects on behavior and performance as well as the cannabinoid blood levels were documented. Conclusion While the oral route of administration achieves only limited blood concentrations, significant psychotic reactions may occur.

    2011-12-01

    Full Text Available Limbic encephalitis (LE is rare, presents with memory impairment, seizures and behavioral disorder. We present a 44-year-old female with an agitation-depressive disorder associated with delusions and hallucinations, admitted to our hospital with the diagnosis of psychosis. A computed tomography (CT scan of the brain and lumbar puncture on admission were normal. Because of clinical deterioration and addition of seizures in the clinical picture, further workup with serum and repeat cerebrospinal fluid studies, magnetic resonance imaging (MRI, and electroencephalogram disclosed a lesion in the left medial temporal lobe consistent with LE. The patient was treated symptomatically with antidepressive, antipsychotic and anticonvulsant drugs. Aggressive diagnostic tests for the presence of an occult cancer were negative. An 8-year follow up has not revealed a tumor to support a paraneoplasmatic origin of LE. This case, initially diagnosed and treated as psychosis, is a case of non-paraneoplasmatic, non-infective LE, probably caused by an autoimmune mechanism.

  7. A Rare Case of Mayer-Rokitansky-Kuster-Hauser Syndrome Presenting with Acute Psychosis.

    2016-04-01

    The psychiatric co-morbidities in female population with mullerian agenesis is an area with limited research. This is probably due to the fact that when those patients are diagnosed not much attention or information is given for long term psychiatric follow-up. Owing to their inability to bear children, these subjects often become socially harassed. Thus these constant stressors may lead to development of psychopathology in future. Mayer-Rokitansky-Kuster-Hauser (MRKH) syndrome is a congenital abnormality with absence of uterus, cervix and vagina, but normal secondary sexual characteristics and external genitalia and occurs in every 1 out of 4000-10,000 females. There is also limited literature on the probable common chromosomal aetiology for both psychosis and MRKH patients. We, present here a case of MRKH syndrome, whose initial presentation was psychosis only. In this respect, we also highlight the much neglected need of appropriate psychiatric screening and provision of psychiatric care in this population. PMID:27190929

    2016-05-01

    The clock-drawing test (CDT) is used widely to evaluate cognitive disorders, but its role in the assessment of psychotic disorders has not been studied. We sought to examine whether the CDT plays a role as an indicator of psychosis and to establish its sensitivity to clinical improvement of psychosis. The CDT was administered twice to 53 hospitalized patients without dementia but with psychosis: once at admission and again before discharge. The CDT scores were calculated in a random order by two independent senior psychiatrists who were blinded to the patients' status (admission or discharge). The inter-rater reliability was high (0.89 at admission, 0.85 at discharge, Ppsychosis was assessed by the Positive and Negative Syndrome Scale (PANSS). Patients had significantly lower CDT scores at admission than at discharge (2.87±1.39 vs. 3.91±1.08, respectively, Ppsychosis severity, as reflected by the PANSS-positive symptom subscale at admission (R=-0.279, P<0.05). Our findings suggest that the CDT may aid in the assessment of psychotic states and in their clinical monitoring. PMID:26752620

  16. Acute psychosis due to non-paraneoplastic anti-NMDA-receptor encephalitis in a teenage girl: Case report.

    2015-12-01

    Anti-N-methyl-d-aspartate receptor (NMDAR) encephalitis is a disease occurring when antibodies produced by the body's own immune system attack NMDA-type glutamate receptors in the brain. Most anti-NMDAR encephalitis cases are associated with paraneoplastic syndrome. We analyze the case of a 15-year-old girl who was hospitalized in a child psychiatry clinic in Riga, Latvia, with de novo acute polymorphic psychotic disorder gradually progressing to a catatonic state. The patient received antipsychotic and electroconvulsive therapy with no beneficial effect. The council of doctors discussed differential diagnoses of schizophrenia-induced catatonia and the autoimmune limbic encephalitis-induced catatonic condition. When the diagnosis of anti-NMDAR autoimmune encephalitis was finally confirmed by repeated immunological assays (specific immunoglobulin [Ig] G and IgM in her blood serum and cerebrospinal fluid), and a paraneoplastic process was ruled out, she was started on immunomodulating therapy (methylprednisolone, Ig, plasmapheresis, rituximab), which changed the course of her disease. On immunomodulating treatment, her physical and mental health have gradually improved to almost complete reconvalescence. Psychiatrists should consider anti-NMDAR encephalitis as a differential diagnosis in first-episode psychosis patients presenting with disorientation, disturbed consciousness, pronounced cognitive deficits, movement disorder, dysautonomia, or rapid deterioration, and test for specific IgG NR1 autoantibodies, even if there are no specific findings on routine neuroimaging, electroencephalography (EEG), or cerebrospinal fluid tests.

  17. Amphetamine-induced psychosis - a separate diagnostic entity or primary psychosis triggered in the vulnerable?

    Bramness Jørgen G

    2012-12-01

    Full Text Available Abstract Use of amphetamine and methamphetamine is widespread in the general population and common among patients with psychiatric disorders. Amphetamines may induce symptoms of psychosis very similar to those of acute schizophrenia spectrum psychosis. This has been an argument for using amphetamine-induced psychosis as a model for primary psychotic disorders. To distinguish the two types of psychosis on the basis of acute symptoms is difficult. However, acute psychosis induced by amphetamines seems to have a faster recovery and appears to resolve more completely compared to schizophrenic psychosis. The increased vulnerability for acute amphetamine induced psychosis seen among those with schizophrenia, schizotypal personality and, to a certain degree other psychiatric disorders, is also shared by non-psychiatric individuals who previously have experienced amphetamine-induced psychosis. Schizophrenia spectrum disorder and amphetamine-induced psychosis are further linked together by the finding of several susceptibility genes common to both conditions. These genes probably lower the threshold for becoming psychotic and increase the risk for a poorer clinical course of the disease. The complex relationship between amphetamine use and psychosis has received much attention but is still not adequately explored. Our paper reviews the literature in this field and proposes a stress-vulnerability model for understanding the relationship between amphetamine use and psychosis.

    Rubinstein-Taybi syndrome (RTS) is a rare genetic disorder with characteristic physical anomalies. It is characterized by mental retardation, postnatal growth deficiency, microcephaly, specific facial characteristics, broad thumbs, and big toes. Behavioral problems are common with RTS; they include mental retardation, impulsivity, distractibility, instability of mood, stereotypes, poor coordination, atypical depression, and mania. To date, there is lack of literature on the presence of schizophrenia or non-affective psychosis with RTS. Here, we describe two cases where there is co-morbid psychosis with RTS. One case is diagnosed as paranoid schizophrenia and the other as psychosis possibly schizophrenia. Genetic analysis was not done due to unavailability. The possible etiological factors for the association of psychosis with RTS are discussed. Factors such as regulators of RNA polymerase II and hypoxia-inducible factor 1 alpha (HIF1A) may be some common etiological factors for the association of schizophrenia or non-affective psychosis and RTS. Schizophrenia / non-affective psychosis can be a comorbid psychiatric condition with RTS. PMID:23162199

  20. Acute psychosis followed by fever: Malignant neuroleptic syndrome or viral encephalitis?

    Stojanović Zvezdana

    2014-01-01

    Full Text Available Introduction. Neuroleptic malignant syndrome is rare, but potentially fatal idiosyncratic reaction to antipsychotic medications. It is sometimes difficult to diagnose some clinical cases as neuroleptic malignant syndrome and differentiate it from the acute viral encephalitis. Case report. We reported a patient diagnosed with acute psychotic reaction which appeared for the first time. The treatment started with typical antipsychotic, which led to febrility. The clinical presentation of the patient was characterised by the signs and symptoms that might have indicated the neuroleptic malignant syndrome as well as central nervous system viral disease. In order to make a detailed diagnosis additional procedures were performed: electroencephalogram, magnetic resonance imaging of the head, lumbar puncture and a serological test of the cerebrospinal fluid. Considering that after the tests viral encephalitis was ruled out and the diagnosis of neuroleptic malignant syndrome made, antipsychotic therapy was immediately stopped. The patient was initially treated with symptomatic therapy and after that with atypical antipsychotic and electroconvulsive therapy, which led to complete recovery. Conclusion. We present the difficulties of early diagnosis at the first episode of acute psychotic disorder associated with acute febrile condition. Concerning the differential diagnosis it is necessary to consider both neuroleptic malignant syndrome and viral encephalitis, i.e. it is necessary to make the neuroradiological diagnosis and conduct cerebrospinal fluid analysis and blood test. In neuroleptic malignant syndrome treatment a combined use of electroconvulsive therapy and low doses of atypical antipsychotic are confirmed to be successful.

  2. Cognitive Restructuring and Graded Behavioural Exposure for Delusional Appraisals of Auditory Hallucinations and Comorbid Anxiety in Paranoid Schizophrenia

    Pawel D. Mankiewicz

    2014-01-01

    Full Text Available The prevalence of diagnostic comorbidity between psychosis and anxiety disorders has been found to be considerable. Cognitive models of psychosis suggest that anxiety does not arise directly from positive symptoms of schizophrenia but rather from an individual interpretation of such experiences. In the United Kingdom, cognitive-behavioural therapy for psychosis (CBTp has been recommended within clinical guidelines as a psychological treatment of choice for those diagnosed with schizophrenia. However, despite empirical evidence supporting CBTp, the treatment provision remains infrequent and not routinely available. This case describes a successful implementation of CBTp. Sixteen sessions were delivered to a 40-year-old male with diagnoses of paranoid schizophrenia and comorbid anxiety, focusing primarily on cognitive restructuring of paranoid appraisals of auditory hallucinations and behavioural experiments employed progressively via graded exposure to anxiety-inducing stimuli. Standardised measurements, behavioural frequency sampling, and subjective data indicated a considerable reduction in both paranoia and anxiety. Also, the client’s psychosocial functioning improved substantially. This report indicates that the treatment may help those with experiences of psychosis and comorbid anxiety reach a significant improvement in their quality of life and offers an encouraging and innovative perspective on direct engagement with the content of paranoia and voices at the onset of therapy.

    Lee, K M; Lin, Y Z; Huang, F Y

    2001-01-01

    A 5-year-old girl was admitted due to severe asthmatic attack. She was treated with methylprednisolone (40 mg i.v. q6h), aminophylline (loading with 5 mg/kg and maintained with 0.6 mg/kg/hr i.v. drip), nebulized terbutaline sulphate (5 mg q6h), oral procaterol 12.5 micrograms bid, along with oxygen therapy. Acute psychotic reaction with visual hallucination, delusion, panic reaction and myoclonic movement of hands developed on day 3 of admission. The patient had no previous history of psychiatric problems. The theophylline level was 9.89 micrograms/ml at the moment of psychotic reaction. After the dose of methylprednisolone was reduced from 40 mg to 20 mg i.v. q6h and shifted to other anti-asthma treatment by procaterol metered dose inhaler via spacer, the psychotic reaction disappeared a few hours later. The psychotic reaction was thought to be due to steroid therapy since no other causes could explain the psychotic reaction. PMID:11431864

    For Freud and Lacan psychosis is not a deficiency. Nowadays, Schreber’s text still remains an unequalled paradigmatic treatise. For Freud, paranoid delirium is an attempt at recovery, and for Lacan it is an attempt to analyze severe logic. The thorny question of psychotic transference still remains. Freud does not believe that a psychotic patient is capable of analytical transference. Lacan thinks that at the beginning, the transference is likely to provoke a trigged of, furthermore the psych...

    2013-11-01

    Full Text Available Introduction: How important is the emotional life of persons who manifest psychotic symptoms? Aims: The aim of this paper is to review evidence on a causal role for emotions in psychotic processes. Methods: Selective review of literature on affective symptoms in psychoses, on emotions in the production of psychotic symptoms and on dopaminergic models of psychosis. Results: Affective symptoms are relevant across psychoses. Persons with schizophrenia have high levels of emotional reactivity and the intensification of negative affects not only is associated with but also precedes the intensification of psychotic symptoms, which is evidence that negative emotions drive the course of psychotic symptoms. Negative self‑representations are central in psychotic processes and can be the link between negative emotions and psychosis. Evidence favours the notion that persecutory delusions are consistent with negative affects and self‑representations, while grandiose delusions are consistent with a defensive amplification of positive affects and self‑representations. Shame has been proposed as the core emotional experience of psychosis, one in which the self becomes vulnerable to the external world, which is consistent with persecutory experiences. Assaults on the self, under the form of hostility in the family environment and society, are strong predictors of relapse and development of schizophrenia. Assaults on the self which induce social defeat are also strong stimulants of mesolimbic dopaminergic pathways, whose hyperactivity is associated with acute psychotic episodes and the experience of “aberrant salience”, put forward as a dopaminergic model of psychosis. Conclusions: The “defeat of the self” emerges as a central link that binds the experience of negative emotions to the expression of psychotic symptoms and its psychological and neurobiological correlates. The hypothesis gains support that the emotions related to that defeat control

    2014-03-01

    Full Text Available Postpartum psychosis is the one of the most severe psychiatric disorder that can be seen during postpartum period. It can be seen between 0.1-0.2 % ratios at postpartum period. It is generally seen in the first two weeks after delivery but in almost 80% of the cases can also be seen until the end of the first month. Risk increases for those who have a positive family history of psychiatric disorder. It is seen more often in primipars, young and those who have psychological disorder history before delivery. Abrupt decrease of serum concentrations of estrogen and progesterone after delivery is suggested in its etiology. Early symptoms of postpartum psychosis may be insomnia and fatigue. The patient may give harm to her baby or herself if develops psychotic features including delusions or hallucinations. Suicidal ideas and suicide attempts may be more prominent than they occur in postpartum depression. It should be treated immediately and effectively due to suicide or homicide risks. If it can not be treated with antipsychotic drugs then electroconvulsive therapy (EKT can be an alternative treatment option. Ninety-five percent of the treated patients with postpartum psychosis recover usually in 2-3 months period. Health workers practicing in first step can play important roles in detection and early management of patients with postpartum psychosis.

  15. Psychosis associated with methimazole-induced hypothyroidism: a case report

    Priscila C. F. Lazaro

    2013-06-01

    Full Text Available INTRODUCTION: Thyroid dysfunction has often been associated with several psychiatric manifestations. Previous case reports/series suggest the possible role played by acute alteration of thyroid status in the onset of psychotic symptoms. METHODS: Case report and literature review. RESULTS: A 45-year-old woman with no psychiatric antecedents was brought to the ER with a full-blown psychotic episode, marked by paranoid delusions, which developed gradually over two months. She had been treated elsewhere for hyperthyroidism for five years with methimazole 40 mg/d, with poor compliance. One month before the beginning of the psychotic symptoms, methimazole was raised to 60 mg/d and she started taking it correctly. Five months earlier she had TSH: 0.074 uUI/ml and free T4: 1.3 ng/dl. At admission we found a diffuse thyroid goiter, TSH: 70.9 uUI/ml and free T4: 0.03 ng/dl. Brain CT was normal. We hospitalized her with the diagnosis of a psychosis secondary to hypothyroidism, suspended methimazole, and gave her levothyroxine (up to 75 µg/d and risperidone (2 mg/d. The patient had a quick remission and was discharged after 15 days. Within one month she had TSH: 0.7 uUI/ml and was completely recovered psychiatrically. She has been well since then, with risperidone in the first 8 months, and without it for 10 months now. CONCLUSION: This case report is a reminder of the necessity of checking thyroid status as part of clinical assessment of psychoses. It also supports the hypothesis that antithyroid drugs may have severe psychiatric consequences, especially when they lead to an acute change of thyroid status.

  16. A study of epilepsy-related psychosis

    2003-07-01

    Full Text Available The association of epilepsy and psychosis is studied. Among the 500 patients of epilepsy evaluated, there were 12 patients, 8 males and 4 females with epilepsy-related psychosis. Their average age was 38 years. The interval between the age of onset of epilepsy and psychotic features was 9 years. Complex partial seizures were present in 7 patients and primary generalized tonic-clonic seizure was present in 1 patient. Four patients had post-ictal psychosis, 7 had acute interictal psychosis and 1 patient had chronic psychosis. The inter-ictal and chronic psychoses were schizophreniform whereas the post-ictal psychoses were not. EEG showed a temporal focus in 7 patients with complex partial seizures and an extra-temporal focus was identified in 4 out of the other 5 patients. Imaging (CT scan/MRI revealed abnormalities in 10 patients. This study attempts to define the characteristics of psychoses occurring in epileptics.

  18. Relationships between paranoid thinking, self-esteem and the menstrual cycle.

    Brock, Rosalind; Rowse, Georgina; Slade, Pauline

    2016-04-01

    This study aimed to investigate whether paranoid experiences and levels of self-esteem fluctuate over the menstrual cycle and whether levels of self-esteem are lower when perceived persecution is felt to be deserved. Measures of anxiety, depression, persecution, deservedness and self-esteem were completed on-line by 278 women over their menstrual cycle. Responses were compared at the paramenstrual (3 days before and after menses onset) and mid-cycle phase. At the paramenstrual phase persecution, negative self-esteem, anxiety and depression were higher and positive self-esteem was lower than at mid-cycle. A greater proportion of women experienced persecution as deserved at the paramenstrual phase. This was associated with higher depression and negative self-esteem scores. Increased levels of deservedness significantly strengthened the relationship between persecution and negative, but not positive, self-esteem. These findings suggest that the paramenstrual phase is a time of vulnerability to increased paranoid experiences, an increased likelihood that feelings of persecution will feel deserved and lowered self-esteem. The findings support the view that interpersonal sensitivities may be key to menstrual cycle symptoms and have an impact on relationships. Further, the study illustrated that ideas developed for psychosis could make a valuable contribution to understanding and managing this aspect of menstruation-related distress. PMID:26260035

    2016-07-30

    Despite a consensus that psychosocial adversity plays a role in the onset of psychosis, the nature of this role in relation to persecutory paranoia remains unclear. This study examined the complex relationship between perceived ethnic discrimination and paranoid ideation in individuals at Ultra High Risk (UHR) for psychosis using a virtual reality paradigm to objectively measure paranoia. Data from 64 UHR participants and 43 healthy volunteers were analysed to investigate the relationship between perceived ethnic discrimination and persecutory ideation in a virtual reality environment. Perceived ethnic discrimination was higher in young adults at UHR in comparison to healthy controls. A positive correlation was observed between perceived ethnic discrimination and paranoid persecutory ideation in the whole sample. Perceived ethnic discrimination was not a significant predictor of paranoid persecutory ideation in the VR environment. Elevated levels of perceived ethnic discrimination are present in individuals at UHR and are consistent with current biopsychosocial models in which psychosocial adversity plays a key role in the development of psychosis and attenuated symptomatology.

    1993-01-01

    Zuclopenthixol acetate--a new injectable formulation with a duration of action of 2-3 days--was compared with conventional intramuscular and oral formulations of haloperidol and zuclopenthixol in the initial treatment of acutely disturbed, psychotic patients. The patients were stratified into 3 diagnostic categories: acute psychoses (48 patients), mania (22 patients), and exacerbation of chronic psychoses (73 patients). The patients were rated on the Brief Psychiatric Rating Scale (BPRS), the Bech-Rafaelsen Mania Rating Scale (BRMAS) (only manic patients) and globally on the Clinical Global Impression (CGI). The study was an open, randomized multicentre trial with a 6-day treatment period. The zuclopenthixol acetate patients received 1-4 doses, the haloperidol patients 1-26 and the zuclopenthixol patients 1-22 doses. The assessments on the CGI showed that all 3 treatments caused a clear reduction of the severity of illness scores in all 3 diagnostic categories, with no differences between treatments. The ratings of the acute and chronic psychotic patients on the BPRS also showed significant reductions in scores with no differences between treatments. All 3 treatments caused a rapid remission of symptoms on the BRMAS. Haloperidol induced hypokinesia in significantly more patients than zuclopenthixol acetate after 24 h. Later there were no significant differences between treatments. Zuclopenthixol acetate fulfils many desires for an amended neuroleptic formulation for the initial treatment of acutely disturbed psychotic patients. PMID:8093824

  5. PET findings in patients with chronic paranoid schizophrenia

    The regional cerebral blood flow (rCBF) of chronic schizophrenic patients with auditory hallucinations and paranoid delusions and normal controls was compared. The subjects were 5 male chronic inpatients (average age of 41.4 yrs, BPRS 29.3±15.0). Normal controls (6 males) were matched for age and sex. rCBF was determined by PET, based on the consecutive inhalation of 15O-CO2. rCBF in the paranoid schizophrenics was significantly higher than that in normal controls in the temporal lobe and cerebellum (p<0.05). rCBF in paranoid schizophrenia showed a tendency to be higher in the frontal lobe, parietal lobe, caudate nucleus, parahippocampus and putamen, but not in the thalamus.

  6. Patients with Paranoid Symptoms: Considerations for the Optometrist

    Mark Bampton, MS

    2013-05-01

    Full Text Available Pathological paranoia involves a pervasive style of thinking and relating to others that is unyielding to reason and is independent of transient influences. Paranoia associated with drug abuse, neurodegenerative disease, and mental health issues will be discussed and care strategies explored. Optometrists will undoubtedly encounter patients with varying degrees and forms of paranoid symptoms. In order to provide the best possible vision care for these patients, it is essential that the optometrist be well prepared for the tension and resistance that is likely to occur during the exam. This paper will focus on patients who exhibit problematic paranoid symptoms and the relevant considerations for optometry.

    Although Japanese tourists in Hawaii are infrequently treated for acute psychiatric emergencies, we observed several cases among Japanese honeymooners. To investigate this phenomenon, we retrospectively and prospectively collected such cases of honeymooners. Sixteen cases of acute psychiatric disturbance in Japanese honeymooners in Hawaii are described. This phenomenon occurs more frequently than in other Japanese tourists or non-Japanese honeymooners. The tradition of arranged marriage and other cultural factors may be associated with the potential for "honeymoon psychosis." PMID:9277018

  11. Dealing with feeling: Specific emotion regulation skills predict responses to stress in psychosis.

    Lincoln, Tania M; Hartmann, Maike; Köther, Ulf; Moritz, Steffen

    2015-08-15

    Elevated negative affect is an established link between minor stressors and psychotic symptoms. Less clear is why people with psychosis fail to regulate distressing emotions effectively. This study tests whether subjective, psychophysiological and symptomatic responses to stress can be predicted by specific emotion regulation (ER) difficulties. Participants with psychotic disorders (n=35) and healthy controls (n=28) were assessed for ER-skills at baseline. They were then exposed to a noise versus no stressor on different days, during which self-reported stress responses, state paranoia and skin conductance levels (SCL) were assessed. Participants with psychosis showed a stronger increase in self-reported stress and SCL in response to the stressor than healthy controls. Stronger increases in self-reported stress were predicted by a reduced ability to be aware of and tolerate distressing emotions, whereas increases in SCL were predicted by a reduced ability to be aware of, tolerate, accept and modify them. Although paranoid symptoms were not significantly affected by the stressors, individual variation in paranoid responses was also predicted by a reduced ability to be aware of and tolerate emotions. Differences in stress responses in the samples were no longer significant after controlling for ER skills. Thus, interventions that improve ER-skills could reduce stress-sensitivity in psychosis.

  12. BDNF-Deficient Mice Show Reduced Psychosis-Related Behaviors Following Chronic Methamphetamine

    Manning, Elizabeth E.; Halberstadt, Adam L.; van den Buuse, Maarten

    2015-01-01

    Background: One of the most devastating consequences of methamphetamine abuse is increased risk of psychosis. Brain-derived neurotrophic factor has been implicated in both psychosis and neuronal responses to methamphetamine. We therefore examined persistent psychosis-like behavioral effects of methamphetamine in brain-derived neurotrophic factor heterozygous mice. Methods: Mice were chronically treated with methamphetamine from 6 to 9 weeks of age, and locomotor hyperactivity to an acute D-am...

  14. Apparent hallucinations in monkeys during around-the-clock amphetamine for seven to fourteen days. Possible relevance to amphetamine psychosis.

    Nielsen, E B; Lyon, M; Ellison, G

    1983-04-01

    Schizophrenia-like symptoms have been experimentally produced in humans by a single, large dose of amphetamine or by relatively low level, but continuous administration of the drug. In animal studies of the psychotomimetic properties of amphetamine, high doses and, in particular, repeated daily-injection drug schedules have often been used. However, amphetamine psychosis is not always a prominent effect of repeated intake drug schedules in humans and available clinical evidence suggests that psychosis develops more readily when the drug is taken in a continuous fashion over longer periods. The state produced by single large doses of amphetamine, although clearly abnormal, has been said to bear less resemblance to schizophrenia than the delayed paranoid symptoms developing after longer periods of continuous intake. In the present experiments we have studied the behavioral effects of 7 to 14 days of continuous administration of amphetamine to monkeys (Cercopithecus aethiops) using subcutaneously implanted silicone capsules releasing approximately .7 to 1.5 mg/kg/day of d-amphetamine base. Around-the-clock TV monitoring of the animals revealed a general biphasic sequence of drug effects, although considerable individual variation occurred: a) an "acute" phase dominated by stereotyped movements and/or prolonged staring, lasting for 2 to 5 days; b) a "late" phase peaking during days 5 to 10 after capsule implantation and characterized by highly individual, but striking sequences of: (1) Attack or sudden threat reactions directed at invisible objects; (2) rapid orienting and flight behavior without apparent cause; (3) sudden startle reactions; (4) prolonged vocalization; (5) visual tracking of invisible objects, sometimes involving coordinated patterns of "eating behavior" and (6) prolonged and rapid grooming directed at various parts of the body. These behaviors might be termed "hallucinatory" since no eliciting stimuli could be determined for their occurrence. Motor

    Grover, Sandeep; Das, Partha Pratim

    2009-01-01

    Bupropion is an antidepressant, which has recently been promoted for the treatment of bipolar depression, because of its lower potency to induced switch. However, due to its dopamine enhancing effect, it has been reported to induce psychosis and perceptual changes. Most of the literature, which is available in relation to development of psychosis while receiving bupropion, has been with the use of immediate release formulation. Some of the case report which have reported development of psycho...

    Alcohol and cannabis misuse is currently the most frequent co-morbidity disorder of schizophrenia. The following four issues will be dealt with: 1) the neurobiological basis of the psychosis-inducing, pathogenic effects of THC, the agent contained in cannabis products. 2) Can cannabis use - and for comparison alcohol abuse - prematurely trigger or even cause schizophrenia? 3) Are persons genetically liable to schizophrenia, psychosis-prone individuals or young persons before completion of bra...

    Psychosis is a leading reason for nursing home placement of patients with Parkinson’s disease (PD). It may also be the single greatest stressor for caregivers of PD patients, it is generally persistent, and its presence markedly increases the risk of mortality. For these reasons, it is essential to recognize and appropriately treat psychosis in PD. Treatment of psychotic symptoms should be initiated after potential medical and environmental causes of delirium (eg, infection) have been elimina...

  18. Migraine madness: recurrent psychosis after migraine.

    Fuller, G N; Marshall, A.; Flint, J.; Lewis, S; Wise, R J

    1993-01-01

    A 69 year old man with longstanding migraine with aura had four episodes of psychosis lasting 7-28 days during a 17 year period. During attacks he had formed visual hallucination and delusions, including reduplicative paramnesia. His mother was similarly affected. His EEG showed symmetrical frontal delta waves. The time course and EEG changes are similar to acute confusional migraine. The reduplicative paramnesia suggests a focal non-dominant hemisphere dysfunction.

  20. Homicide during postictal psychosis

    Stephan Eisenschenk

    2014-01-01

    Full Text Available Postictal psychosis is characterized by a fluctuating combination of thought disorder, auditory and visual hallucinations, delusions, paranoia, affective change, and aggression including violent behavior. We present a case of homicide following a cluster of seizures. The patient's history and postictal behavior were his consistent with postictal psychosis. Contributing factors resulting in homicide may have included increased seizure frequency associated with a change in his AED regimen seizure frequency. The AED change to levetiracetam may also have increased impulsiveness with diminished mood regulation following discontinuation of carbamazepine. There is evidence that he had a cluster of seizures immediately prior to the murder which may have resulted in the postictal disinhibition of frontal lobe inhibitory systems. This homicide and other violent behaviors associated with postictal psychosis may be avoided with earlier recognition and treatment.

  2. 1-123 iodoamphetamine SPECT findings in paranoid schizophrenia

    To find out if frontal metabolic and cerebral blood flow differ between normal subjects and patients with paranoid schizophrenia (PAR), the authors have examined regional synaptic amine metabolism. Using [I- 123]iodoamphetamine (IMP), the authors compared 85 subjects (61 PAR patients and 24 normal subjects) with single-head single-photon emission CT (SPECT). Virtually automatic analysis assigned relative tracer uptake to the frontal, anterior temporoparietal (TP), and posterior TP regions. Consistent with the visual inspection of two clinicians familiar with SPECT IMP images, this objective method yielded T-tests that showed higher relative frontal lobe ratios in normal subjects than in PAR patients (P =.03)

  7. Association of Huntington's disease and schizophrenia-like psychosis in a Huntington's disease pedigree

    Guimarães João

    2006-02-01

    Full Text Available Abstract Background Huntington's disease (HD is a dominantly inherited, neurodegenerative disorder due to expansion of a polymorphic trinucleotide repeat in the short arm of chromosome 4. Clinical manifestations consist of a triad of choreic movements, cognitive decline and psychiatric syndromes starting in the fourth to fifth decade. Psychiatric manifestations vary and may precede motor and cognitive changes. Personality changes and depression occur most commonly. Paranoid schizophrenia-like symptoms occur in 6% to 25% of cases. Case report We describe a 55 year-old woman with an 8 yearlong history of behavioural changes, multi-thematic delusions and auditory hallucinations. History and mental state examination were suggestive of paranoid schizophrenia. Neurological examination revealed discrete, involuntary movements affecting her arms and trunk. Genotyping detected an expanded allele (43 trinucleotide repeats. A three-generation-long family history of chorea and schizophrenia-like psychosis was found. Conclusion HD-families have been reported in which schizophrenia-like syndromes emerged in all or most HD-affected members long before they developed extra-pyramidal or cognitive changes. This has been attributed to more than mere coincidence. We hypothesise that in these families the HD gene is transmitted along with a low load of small-effect "psychosis genes" which, in the presence of the severe cognitive changes of HD, manifest as a schizophrenia-like phenotype. Further research is needed in order to clarify the links between genetic loading and the emergence of psychotic symptoms in Huntington's disease.

  8. Severe Psychosis, Drug Dependence, and Hepatitis C Related to Slamming Mephedrone

    Helen Dolengevich-Segal

    2016-01-01

    Full Text Available Background. Synthetic cathinones (SCs, also known as “bath salts,” are β-ketone amphetamine compounds derived from cathinone, a psychoactive substance found in Catha edulis. Mephedrone is the most representative SC. Slamming is the term used for the intravenous injection of these substances in the context of chemsex parties, in order to enhance sex experiences. Using IV mephedrone may lead to diverse medical and psychiatric complications like psychosis, aggressive behavior, and suicide ideation. Case. We report the case of a 25-year-old man admitted into a psychiatric unit, presenting with psychotic symptoms after slamming mephedrone almost every weekend for the last 4 months. He presents paranoid delusions, intense anxiety, and visual and kinesthetic hallucinations. He also shows intense craving, compulsive drug use, general malaise, and weakness. After four weeks of admission and antipsychotic treatment, delusions completely disappear. The patient is reinfected with hepatitis C. Discussion. Psychiatric and medical conditions related to chemsex and slamming have been reported in several European cities, but not in Spain. Psychotic symptoms have been associated with mephedrone and other SCs’ consumption, with the IV route being prone to produce more severe symptomatology and addictive conducts. In the case we report, paranoid psychosis, addiction, and medical complications are described.

  10. Trauma, posttraumatic stress disorder and psychosis: etiopathogenic and nosological implications

    Álvaro Frías Ibáñez

    2014-03-01

    Full Text Available Background and Objectives: The relationship between trauma, post-traumatic stress disorder (PTSD, and psychosis has promoted heterogeneous research lines, in both etiopathogenic and nosological areas. The main aim of this review is to provide a systematic framework that encompasses this theoretical gap in the literature. Methods: A literature research was carried out through PubMed and PsycINFO between 1980 and May 2013. One hundred and thirteen articles were recruited. A first part of this review describes the role of trauma in the development of psychosis. The second part focuses on research about PTSD and psychosis. Results: Longitudinal and cross-sectional studies with clinical and community samples confirm that childhood trauma (CT is a vulnerability factor for schizophrenia and psychotic-like symptoms in adulthood. More empirical research is needed in order to assess the role of trauma as precipitant of acute psychosis. There is also preliminary evidence with cross-sectional samples that suggests that PTSD and psychosis are a risk factor for each other, with studies about post-psychotic PTSD (PP-PTSD being outstanding. Finally, results from different comparative research studies postulate a subtype of PTSD with psychotic features (PTSD-SP. Conclusions: The role of trauma in psychosis is more conclusive as predispositional rather than as trigger factor. Nosological status of acute psychoses remains a focus of controversy unresolved. The association between PTSD and psychosis is complex, requiring more prospective research in order to determine causal relationships between these pathologies. Also, research in nosological status of PTSD-SP must encourage more comparative studies not limited to neurobiological variables.

  11. Multivariate analyses of CT findings in typical schizophrenia and atypical psychosis

    In order to investigate the brain morphological differences between typical schizophrenia and atypical psychosis, the brain CTs of 41 patients with typical schizophrenia, 27 patients with atypical psychosis (ATP), and 20 controls were examined. The schizophrenics had larger values for 9 CT indices, i.e., interhemispheric fissure (IHF) index, VBR, 2 lateral ventricles (L-V) and 3rd venricle (III-V) indices, and 4 sylvian fissure (SF) indices, while the values of ATP patients for 3 SF indices were greater than for the controls. Moreover, the schizophrenics had greater III-V and L-V indices than the ATP patients. The correlation matrix of CT indices indicates that the III-V index correlated well with the other CT indices, whereas the VBR, IHF and right SF indices did not. Therefore, it was speculated that there might be 3 subgroups, each of which has a main focus of alteration in the above-mentioned regions. Therefore, all the cases were divided by means of a cluster analysis into 5 groups. Group I, which contained mainly normal controls, and Group II, which consisted mainly of atypical psychosis patients, had no abnormal CT findings. Group III, which comprised mainly ATP pateints and paranoid type schizophrenics, had right SF enlargement. Group IV, which showed significant IHF enlargement, and the residue group, which had larger VBR and significant left SF enlargement, consisted mostly of schizophrenics. Thus, our results suggest that the classification by CT data corresponds on the whole to our clinical diagnosis, according to which schizophrenic psychosis is divided into typical schizophrenia and atypical psychosis, and that each of the two psychosis groups may be further classified into distinct subgroups.

    Full Text Available "nObjective: Inconsistent results have been reported regarding the symptom dimensions relevant to psychosis in symptoms check list revised (SCL90-R, i.e., "psychoticism" and "paranoid ideation". Therefore, some studies have suggested different factor structures for questions of these two dimensions, and proposed two newly defined dimensions of "schizotypal signs" and "schizophrenia nuclear symptoms". We conducted an exploratory factor analysis on the items of these two dimensions in a general population sample in Iran. "nMethod: A total of 2158 subjects residing in Southern Tehran (capital of Iran were interviewed using the psychoticism and paranoid ideation questions in SCL90-R to assess severity of these symptom dimensions. Factor analysis was done through SAS 9.1.3 PROC FACTOR using Promax rotation (power=3 on the matrix of "polychoric correlations among variables" as the input data. "nResults: Two factors were retained by the proportion criterion. Considering loadings >= 0.5 as minimum criteria for factor loadings, 7 out of 10 questions  from psychoticism ,and 3 out of 6 questions from paranoid ideation were retained, and others were eliminated. The factor labels proposed by the questionnaire suited the extracted factors and were retained. Internal consistency for each of the dimensions was acceptable (Cronbach's alpha 0.7 and 0.74 for paranoid ideation and psychoticism respectively. Composite scores showed a half-normal distribution for both dimensions which is predictable for instruments that detect psychotic symptoms. "nConclusion: Results were in contrast with similar studies, and questioned them by suggesting a different factor structure obtained from a statistically large population. The population in a developing nation (Iran in this study and the socio-cultural differences in developed settings are the potential sources for discrepancies between this analysis and previous reports.

  14. Cycloid psychosis: Perris criteria revisited

    Yadav Devender

    2010-01-01

    Full Text Available Cases presenting with recurrent confusion, alteration of psychomotor activity, and brief psychosis with good inter-episode recovery have many differing etiologies. Only rarely does one diagnose such cases as cycloid psychosis. Even among budding psychiatrists, there seems to be a lack of awareness of this unique disorder. This may be because the present international diagnostic classification systems, ICD10 and DSM IV, do not recognize it as a separate entity. A high index of suspicion is required to diagnose cycloid psychosis. Awareness and recognizing such cases would be helpful clinically as cycloid psychosis entails a distinct prognosis and may require a specific treatment.

  16. Early psychosis symptoms

    Objective: To determine the prodromal symptoms of schizophrenia in the pathways to help-seeking. Study Design: A cross-sectional study. Place and Duration of Study: The Department of Psychiatry, the Aga Khan University, Karachi, from 2008 to 2009. Methodology: A total of 93 patients were interviewed in the pathways to care of schizophrenia. The diagnosis was based on ICD-10 criteria. The pathways to care were assessed through a semi-structured questionnaire. The onset, course and symptoms of psychosis were assessed through Interview for Retrospective Assessment at Age at Onset of Psychosis (IROAS). Results: Fifty five (59%) participants were male while 41% (n=38%) were female. Using IROAS, 108 symptoms were identified as concerning behaviour. Alternatively, 60 (55%) concerning behaviours were reported in the open-ended inquiry of the reasons for help seeking as assessed by the pathways to care questionnaire with a statistically significant difference between most symptoms category. The difference was most pronounced (p < 0.001) for depressed mood (66%), worries (65%), tension (63%), withdrawal/mistrust (54%) and loss of self-confidence (53%). Thought withdrawal (22%) and passivity (15%) were elicited only through structured interview (IROAS). When symptoms were categorized together, about 83% of the subjects presented with affective and non-specific prodromal symptoms. Roughly, 10% of the subjects presented with positive symptoms and 3% presented with the negative symptoms of psychosis. The non-specific, affective symptoms appear to predominate the prodromal phase of the illness. Conclusion: Prodromal symptoms of schizophrenia include non-specific, affective symptoms. Attention needs to be paid on identifying the prodromal symptoms and change in social functioning in order to identify those who are at risk of long term psychosis. (author)

  17. Brain dysfunction in psychosis

    The present investigation focused on the questions whether previously reported functional brain abnormalities in schizophrenia could be related to the clinical state of the patient (i.e. the degree of psychosis) at time of study, and whether similar findings in patients with schizophrenia, could be made in patients with cycloid psychosis. To this effect, patients were investigated with regional cerebral blood flow measurements and clinical rating on repeated occasions during their most extreme fluctuations during a psychotic episode, i.e. while they were in an exacerbated state and during clinical remission. A subgroup of schizophrenic patients were investigated before and after neuroleptic treatment and during mental activation with a word fluency test. The schizophrenic group has a normal mean hemispheric blood flow irrespective of clinical state and treatment. During exacerbation a highly significant positive correlation was seen between the frontal-occipital (F/O) ratio and the degree of psychosis, suggesting that the more psychotic the patients was, the higher was the ratio. During remission, the F/O ratio decreased. Schizophrenic patients did not activate their prefrontal cortex during exacerbation, but showed a normal frontal response to the word fluency test during remission. The regional cerebral blood flow of the cycloid patients differed clearly from that of the schizophrenic patients. During exacerbation they had elevated mean hemispheric flow levels, and a decreased F/O ration, while rCBF was normal during remission. The findings suggest that variability in the degree of psychosis can be an important factor underlying the heterogeneity of rCBF findings in schizophrenia. (au)

  19. Contemporary Perspectives on Lacanian Theories of Psychosis

    Jonathan Douglas Redmond

    2013-06-01

    Full Text Available Abstract:In contemporary Lacanian psychoanalysis, Verhaeghe’s theory of actualpathology / psychopathology in psychosis and the Millerian idea of ordinary psychosis provide diverging conceptual approaches to psychosis. In this paper, the two approaches to psychosis are examined with a particular emphasis on mild psychosis and compensatory mechanisms. Despite the shared focus on similar clinical phenomena, particularly body disturbances, these two theories provide different explanations of psychosis. Verhaeghe’s theory of psychosis is a synthesis of Lacanian theory, Freud’s idea of actual neurosis and psychoanalytic attachment concepts. Moreover, these ideas are situated in the schizophrenia / paranoia dichotomy an important heuristic device utilised in clinical practice with psychosis. In contrast, the Millerian field of ordinary psychosis aims to broaden the idea of psychosis by reviving the idea of mild psychosis and the different forms of stabilisation possible in psychosis. Clinicians adapting the idea of ordinary psychosis aim to rethink pivotal Lacanian concepts - untriggered psychosis and stabilisation - beyond the scope of the schizophrenia / paranoia dichotomy. Although the idea of ordinary psychosis requires further development, it promise greater utility than Verhaeghe’s model, as it provides a broader and more nuanced approach to the complex vicissitudes of triggering and restitution in psychosis.

  4. Assessing and Treating the Patient with Acute Psychotic Disorders.

    Jensen, Lisa; Clough, Rebecca

    2016-06-01

    Patients with acute psychosis often present to emergency departments. Management of acute agitation and psychosis can be a challenge for the staff. Medical stabilization, appropriate assessment, and diagnosis are important. Verbal de-escalation and other psychosocial interventions are helpful in creating a safe and therapeutic environment. Psychiatric and emergency room nurses are poised to treat patients presenting with acute psychosis and must be knowledgeable of evidence-based approaches to treat these complex disorders.

    2015-01-01

    N-methyl-d-aspartate receptor (NMDA-R) autoantibodies have been reported in people with acute psychosis. We hypothesised that their presence may be implicated in the aetiology of treatment-refractory psychosis. We sought to ascertain the point prevalence of NMDA-R antibody positivity in patients referred to services for treatment-refractory psychosis. We found that 3 (7.0%) of 43 individuals had low positive NMDA-R antibody titres. This suggests that NMDA-R autoantibodies are unlikely to acco...

  7. Psychosis and cannabis

    Heinz Häfner

    2005-01-01

    Full Text Available Alcohol and cannabis misuse is currently the most frequent co-morbidity disorder of schizophrenia. The following four issues will be dealt with: 1 the neurobiological basis of the psychosis-inducing, pathogenic effects of THC, the agent contained in cannabis products. 2 Can cannabis use - and for comparison alcohol abuse - prematurely trigger or even cause schizophrenia? 3 Are persons genetically liable to schizophrenia, psychosis-prone individuals or young persons before completion of brain development at an increased risk? 4 What consequences does cannabis use have on the symptomatology and further course of schizophrenia? Results from recent literature and the ABC Schizophrenia Study show that the risk for cannabis use in schizophrenia is about twice the size in healthy controls. In most cases cannabis use starts before first admission, in a third of cases before schizophrenia onset. There is an increased affinity to misuse already at the prodromal stage. Cannabis can prematurely trigger schizophrenia onset - on average eight years earlier than in non-use - and cause the illness partly in interaction with predisposing factors. Cannabis use in the course of schizophrenia increases positive symptoms and reduces affective flattening, thus leading to dysfunctional coping in some cases.

    Recently, social anxiety disorder (SAD) and paranoia have been demonstrated to be closely related. However, data were primarily drawn from adult community samples or patients with schizophrenia. The present study used a cross-sectional design to evaluate a sample of adolescents with SAD (n = 30, mean age 15.3 ± 0.9 years) compared with an age- and sex-matched group of healthy controls (n = 26, mean age 15.9 ± 1.6 years). The SAD group displayed more frequent and intense paranoid thoughts than the control group (t = 4.16, p anxiety disorders, although adjusting for depression slightly reduced the extent and significance of the prediction. A lack of awareness about the association between SAD and paranoia may lead to incorrect diagnoses (e.g. misdiagnosis of psychotic disorders), or it may negatively influence the (psycho)therapeutic process and patient outcomes.

    Unlike the cognitive dimensions, alterations of the affective components of empathy in schizophrenia are less well understood. This study explored cognitive and affective dimensions of empathy in the context of the subjective experience of aspects of emotion processing, including emotion regulation, emotional contagion, and interpersonal distress, in individuals with schizophrenia and healthy controls. In addition, the predictive value of these parameters on psychosocial function was investigated. Fifty-five patients with paranoid schizophrenia and 55 healthy controls were investigated using the Multifaceted Empathy Test and Interpersonal Reactivity Index, as well as the Subjective Experience of Emotions and Emotional Contagion Scales. Individuals with schizophrenia showed impairments of cognitive empathy, but maintained emotional empathy. They reported significantly more negative emotional contagion, overwhelming emotions, lack of emotions, and symbolization of emotions by imagination, but less self-control of emotional expression than healthy persons. Besides cognitive empathy, the experience of a higher extent of overwhelming emotions and of less interpersonal distress predicted psychosocial function in patients. People with schizophrenia and healthy controls showed diverging patterns of how cognitive and emotional empathy related to the subjective aspects of emotion processing. It can be assumed that variables of emotion processing are important moderators of empathic abilities in schizophrenia. PMID:25288043

    We report the case of a 32-year-old male transsexual patient with unipolar mania. Since the onset of his affective psychosis, alternating states of male and female identification were observed. The patient himself behaved as a woman only in manic phases. Possible relations between transsexuality and affective psychosis are discussed, together with a short review of the literature, especially psychodynamic theories on the genesis of transsexuality.

  11. Acute Administration of MK-801 in an Animal Model of Psychosis in Rats Interferes with Cognitively Demanding Forms of Behavioral Flexibility on a Rotating Arena

    Jan eSvoboda

    2015-04-01

    Full Text Available Patients with schizophrenia often manifest deficits in behavioral flexibility. Non-competitive NMDA receptor antagonists such as MK-801 induce schizophrenia-like symptoms in rodents, including cognitive functions. Despite work exploring flexibility has been done employing behavioral paradigms with simple stimuli, much less is known about what kinds of flexibility are affected in an MK-801 model of schizophrenia-like behavior in the spatial domain. We used a rotating arena-based apparatus (Carousel requiring rats to avoid an unmarked sector defined in either the reference frame of the rotating arena (arena frame task, AF or the stationary room (room frame task, RF. We investigated behavioral flexibility in four conditions involving different cognitive loads. Each condition encompassed an initial (five sessions and a test phase (five sessions in which some aspects of the task were changed to test flexibility in which rats were given saline, 0.05 mg/kg or 0.1 mg/kg MK-801 thirty minutes prior to a session. In the first condition, rats acquired avoidance in RF with clockwise rotation of the arena while in the test phase the arena rotated counterclockwise. In the second condition, rats initially acquired avoidance in RF with the sector on the north and then it was reversed to south (spatial reversal. In the third and fourth conditions, rats initially performed an AF (RF, respectively task, followed by an RF (AF, respectively task, testing the ability of cognitive set-shifting. We found no effect of MK-801 either on simple motor adjustment after reversal of arena rotation or on spatial reversal within the RF. In contrast, administration of MK-801 at a dose of 0.1 mg/kg interfered with set-shifting in both conditions. Furthermore, we observed MK-801 0.1 mg/kg elevated locomotion in all cases. These data suggest that blockade of NMDA receptors by acute system administration of MK-801 preferentially affects set-shifting in the cognitive domain rather

  12. Brave new worlds--review and update on virtual reality assessment and treatment in psychosis.

    Veling, Wim; Moritz, Steffen; van der Gaag, Mark

    2014-11-01

    In recent years, virtual reality (VR) research on psychotic disorders has been initiated. Several studies showed that VR can elicit paranoid thoughts about virtual characters (avatars), both in patients with psychotic disorders and healthy individuals. Real life symptoms and VR experiences were correlated, lending further support to its validity. Neurocognitive deficits and difficulties in social behavior were found in schizophrenia patients, not only in abstract tasks but also using naturalistic virtual environments that are more relevant to daily life, such as a city or encounters with avatars. VR treatments are conceivable for most dimensions of psychotic disorders. There is a small but expanding literature on interventions for delusions, hallucinations, neurocognition, social cognition, and social skills; preliminary results are promising. VR applications for assessment and treatment of psychotic disorders are in their infancy, but appear to have a great potential for increasing our understanding of psychosis and expanding the therapeutic toolbox.

    2005-01-01

    The use of complimentary/alternative medicine has become popular as evidenced by grocery store aisles and “infomercials” devoted to herbal products. These products are often misconstrued as safe because of their natural origin. With an increase in the consumption of these products, physicians need to be aware of their potential adverse effects. There are several popular over-the-counter herbal products that can affect one's behavior, especially resulting in acute mania and/or psychosis. This ...

  14. Ziconotide-induced psychosis: a case report.

    Phan, Stephanie V; Waldfogel, Julie M

    2015-01-01

    Ziconotide is used intrathecally in the management of severe chronic pain that contains a warning against neuropsychiatric adverse events. The definition of psychiatric events is broad and management strategies are vague. This case report describes a 49-year-old female who was admitted to the acute psychiatric unit to address auditory hallucinations and paranoid ideation persisting for 3 weeks. Approximately 3 months ago, an intrathecal pump with ziconotide was implanted to treat pain. Upon hospital admission, the pump was infusing at a rate of 4.9 mcg/24 hours. Because the drug could not be immediately discontinued, risperidone 0.5 mg nightly was initiated and subsequently, the pump was drained of ziconotide, rinsed, and refilled with normal saline. The patient reported no hallucinations or apparent delusions several hours later and was eventually discharged with resolution of psychotic symptoms and continuation of risperidone for 10 days. Despite the identification of neuropsychiatric effects, limited information is available to characterize the presentation and guide specific management aside from recommendations to discontinue the infusion and possible use of psychotropic medications or necessity for hospitalization. This case report characterizes one presentation of hallucinations and paranoia associated with ziconotide intrathecal infusion. Clinicians should be aware of the management strategies to mediate these adverse effects, including expected time to adverse effect resolution, removal of ziconotide from the pump, and role for short-term use of antipsychotics.

  17. Caregiver psychoeducation for first-episode psychosis.

    McWilliams, Stephen

    2010-01-01

    International best-practice guidelines for the management of first-episode psychosis have recommended the provision of psychoeducation for multifamily groups. While there is ample evidence of their efficacy in multiepisode psychosis, there is a paucity of evidence supporting this approach specifically for first-episode psychosis. We sought to determine whether a six-week caregiver psychoeducation programme geared specifically at first-episode psychosis improves caregiver knowledge and attitudes.

  20. BIOMETRIC INDICES OF CONSTITUTIONAL RISKS FOR DEVELOPMENT OF PARANOID SCHIZOPHRENIA IN MALE PATIENTS

    Lebedeva Е.A

    2009-09-01

    Full Text Available Aim: the current study examines features and correlations of particular psychodynamic, dermatoglyphic characteristics and body constitution of men with paranoid schizophrenia. Study groups: 25 men having the "paranoid schizophrenia" (F20.0, 27 men having no mental diseases. Methods: psychodiagnostic tests (Hand test, the Big Five Inventory (BFI, anthropometry; dactyloscopy. Results: there were statistically significant differences in such personality factors as: extroversion and openness among two groups. Significantly smaller sizes of the chest and thigh circumferences were found in men with paranoid schizophrenia. The schizophrenic group exhibited higher frequency of "ulnar loop" and "double loop" finger pattern occurrence. Our study found a number of somato-psychic, dermato-psychic and dermato-somatic correlations, as well as correlations between personality factors and age. Conclusion: the examination of personality features correlated with markers of dermatoglyphic and body constitution helped to identify the predictors of risks for developing paranoid schizophrenia. This makes it possible the identification of at-risk groups with their monitoring and focusing on preventive programs

  1. Self psychology as a shift away from the paranoid strain in classical analytic theory.

    Terman, David M

    2014-12-01

    Classical psychoanalytic theory has a paranoid strain. There is, in effect, an "evil other"--the id--within each individual that must be tamed in development and confronted and worked through as resistance in treatment. This last has historically endgendered an adversarial relationship between patient and analyst. This paranoid strain came from a paranoid element in Freud's personality that affected his worldview, his relationships, and his theory. Self psychology offers a different view of development and conflict. It stresses the child's need for responsiveness from and admiration of caretakers in order to develop a well-functioning self. Though severe behavioral and character problems may result from faults in the process of self-construction, the essential need is not instinctual discharge but connection. Hence the long-assumed opposition between individual needs and social institutions or between patient and analyst is no longer inevitable or universal. Rather, an understanding of the primary need for connection creates both a different interpretive stance and a more cooperative ambience. These changes in theory and technique are traced to Kohut's personal struggles to emancipate himself from his paranoid mother. PMID:25339303

    The identification and distinction of the pathological conditions underlying acute psychosis are often challenging. We present the case of a 35-year-old ranger who had no history of acute or chronic infectious disease or any previous neuropsychiatric symptoms. He arrived at the Psychiatry Clinic and was admitted as an emergency case, displaying bizarre behavior, hallucinations, paranoid ideation, and delusional faults. These symptoms had first appeared 7 days earlier. An objective examination revealed abnormalities of behavior, anxiety, visual hallucinations, choreiform, and tic-like facial movements. After the administration of neuroleptic and antidepressant treatment, he showed an initial improvement, but on day 10 entered into a severe catatonic state with signs of meningeal irritation and was transferred to the intensive care unit. An electroencephalogram showed diffuse irritative changes, raising the possibility of encephalitis. Taking into consideration the overt occupational risk, Borrelia antibody tests were prescribed and highly positive immunoglobulin (Ig)M and IgG titers were obtained from serum, along with IgG and antibody index positivity in cerebrospinal fluid. In parallel, anti-N-methyl-D-aspartate receptor antibodies and a whole battery of other autoimmune encephalitis markers showed negative. A complex program of treatment was applied, including antibiotics, beginning with ceftazidime and ciprofloxacin – for suspected aspiration bronchopneumonia – and thereafter with ceftriaxone. A gradual improvement was noticed and the treatment continued at the Infectious Disease Clinic. Finally, the patient was discharged with a doxycycline, antidepressant, and anxiolytic maintenance treatment. On his first and second control (days 44 and 122 from the disease onset), the patient was stable with no major complaints, Borrelia seropositivity was confirmed both for IgM and IgG while the cerebrospinal fluid also showed reactivity for IgG on immunoblot.

  6. An unusual presentation of brief recurrent psychosis: a case report

    Krishnamurthy CN

    2012-12-01

    Full Text Available Background: Although the term "zycloiden psychosen" was first used by Karl Kleist in 1926 to group together disorders, which had presented with sudden onset, brief episodic course, polymorphous psychotic symptoms and good inter-episode recovery, its origin can be traced back to 1880s. Despite its existence in the community, for so long, the diagnosis of cycloid psychosis is only seldom made, making it a unique disorder. Hence, there seems to be lack of awareness of this rare entity even among the psychiatrists.Case description: A middle-aged woman with abrupt onset of recurrent brief episodes of psychotic symptoms, and complete inter-episode recovery, was admitted with history of alleged consumption of poison in a state of confusion. During psychotic episodes, motility disturbances were predominant. The current episode lasted for about two weeks.Discussion: This case doesn't satisfy the criteria for schizophrenia or affective illness. Although ICD-10 describes 'acute polymorphic psychotic disorder' (F23.0, F23.1 it requires the presence of typical schizophrenic symptoms for its diagnosis and is usually not recurrent. The closest this case resembles is cycloid psychosis, meeting three of four Perris criteria.Conclusion: The diagnosis of such unusual cases of psychosis predicts the prognosis and helps in assessment and management of future episodes.

  7. [Young person's first-episode psychosis].

    Mäki, Pirjo; Veijola, Juha

    2012-01-01

    Young person's first-episode psychosis may signify the onset of schizophrenia, psychotic depression or bipolar disorder. It can also be a brief condition resulting in full recovery. The psychosis may be caused by drugs. First-episode psychosis is usually preceded by a long period of nonspecific symptoms. Provision of close and active follow-up is important in the prodromal phase. Treatment of first-episode psychosis is individual. Usually it involves medication, individual discussions, psychotherapy or music therapy as well as family meetings. The therapy helps the young person become independent. PMID:22312825

    2002-12-01

    Through a few clinical case histories stemming from their daily activities at the psychiatric section of the Lantin Prison, the authors propose to revisit the classic concept of Prison psychosis. They broaden its limits to include other psychotic and dissociative phenomena common to the jail population. This requires a strict differential diagnosis, allowing to eliminate some similar pathologies; nevertheless, some difficulties and imperfections persist. The development of the psychosis, the input from the jail architecture and milieu, the predisposing as well as facilitating factors linked to the personality of the inmate, and triggering phenomena are discussed. Finally, the comorbidity between these psychotic/dissociative phenomena and the borderline & histrionic personality disorders is envisaged. PMID:12632838

    2016-01-01

    Synthetic cannabinoids- (SCs-) induced psychosis is a growing public health concern. It leads to significant impairment, including emotional distress, difficulty communicating, and other debilitating symptoms. In this case report, we discuss a patient with no previous history of psychotic symptoms, presenting with first-episode psychosis in the context of progressive, acutely worsening, disorganized, psychotic thoughts and behaviors following prolonged use of SCs. We also discuss relevant literature on SCs-induced psychosis, highlighting its prevalence, presentation, diagnosis, and recommended management. It is important to diagnose and treat SCs-induced psychosis as early and efficiently as possible, in order to alleviate symptoms while limiting functional impairment and emotional distress to the patient.

  16. ADD psychosis as a separate entity.

    Bellak, L

    1985-01-01

    "Attention deficit disorder (ADD) psychosis" merits delineation as a separate entity. It constitutes the end result of the effects of a certain particular neurological deficit (ADD) on personality organization. It is my belief that about 10 percent of psychoses currently diagnosed most often schizophrenic and sometimes affective psychosis must best be considered a separate organic psychosis, i.e., an ADD psychosis. This ADD psychosis, then, is not merely a subgroup of schizophrenia, as I once thought. It merits a separate designation because its etiology, pathogenesis, and life history are different from those of the schizophrenic syndrome. The family histories are also different, as are the psychological findings. The treatment response is so different that it merits urgent consideration. Prognosis, both short range and long range, also seems different from those of the other psychoses. PMID:4081648

    pruning of excitatory synapses. Silent spots are the result of insufficient fill-in mechanisms following a breakdown of circuitry. They may affect the SMA in the case of very late puberty. An acute reduction in excitation and concomitantly a marked increase in silent spots might lead to an acute psychosis. A frontal preference is likely, given that a reduction might occur anywhere in the cortex, but particularly in the areas maturing latest. The varying localisations probably explain the difficulty in accepting schizophrenia as a disease entity. The multifactorial inheritance of the dichotomy implies that the genetics are not fate, a psychotic development might be prevented given enough epigenetic factors: brain food (omega 3). Might the present dietary adversity, with its lack of brain food, be responsible for a rising incidence in psychosis? A psychosis is an understandable and preventable dysfunction of the brain, and its mechanisms are known. Primarily a disorder of reduced excitation in an attenuated CNS, this explains why all the neuroleptics are convulsants, raising excitation, in contrast to all antidepressives, which are anti-epileptic.

    Some of the most compelling evidence supporting an association between cannabinoid agonists and psychosis comes from controlled laboratory studies in humans. Randomized, double-blind, placebo-controlled, crossover laboratory studies demonstrate that cannabinoid agonists, including phytocannabinoids and synthetic cannabinoids, produce a wide range of positive, negative, and cognitive symptoms and psychophysiologic deficits in healthy human subjects that resemble the phenomenology of schizophrenia. These effects are time locked to drug administration, are dose related, and are transient and rarely necessitate intervention. The magnitude of effects is similar to the effects of ketamine but qualitatively distinct from other psychotomimetic drugs, including ketamine, amphetamine, and salvinorin A. Cannabinoid agonists have also been shown to transiently exacerbate symptoms in individuals with schizophrenia in laboratory studies. Patients with schizophrenia are more vulnerable than healthy control subjects to the acute behavioral and cognitive effects of cannabinoid agonists and experience transient exacerbation of symptoms despite treatment with antipsychotic medications. Furthermore, laboratory studies have failed to demonstrate any "beneficial" effects of cannabinoid agonists in individuals with schizophrenia-challenging the cannabis self-medication hypothesis. Emerging evidence suggests that polymorphisms of several genes related to dopamine metabolism (e.g., COMT, DAT1, and AKT1) may moderate the effects of cannabinoid agonists in laboratory studies. Cannabinoid agonists induce dopamine release, although the magnitude of release does not appear to be commensurate to the magnitude and spectrum of their acute psychotomimetic effects. Interactions between the endocannabinoid, gamma-aminobutyric acid, and glutamate systems and their individual and interactive effects on neural oscillations provide a plausible mechanism underlying the psychotomimetic effects of

  19. [Current peculiarities of alcoholic psychosis].

    2011-01-01

    The follow-up study of alcoholic psychoses in male patients admitted to a clinical department of a psychiatric hospital in 2005-2007 was carried out. Patients with alcoholic psychoses made up from 15 to 30% of all patients. The number of psychosis had seasonal variations with the elevations in spring and autumn, peaks in January, lune and October. Alcoholic delirium morbidity made up from 69 to 82% of the total number of alcoholic psychoses, alcoholic hallucinosis varied from 14 to 27%. Other forms were presented by single cases. In alcoholic delirium hallucinations had brighter, sated character. The most specific were visual hallucinations in the form of zoohallucinations, hallucinations of an oral cavity ("sensation of threads, hair etc"). The most often observable characters were "extraneous people, animal, demons". In alcoholic hallucinosis, verbal contrast hallucinations, making comment hallucinations, visual illusions were most frequent. The family history of mental disorders and alcoholism was noted in 30% of patients with alcoholic psychosis. The probability of occurrence of alcoholic psychoses depended on the quality of consumed drinks. The presence of a cranial-brain injury in the anamnesis considerably aggravated the disease forecast and increased the risk of seizure syndrome. PMID:22611692

    Full Text Available Abstract Background There were few studies on the outcome of schizophrenia in developing countries. Whether the outcome is similar to or different from developed world is still a point for research. The main aim of the current study was to know if patients with early onset non affective psychosis can behave and function properly after few years from start of the illness or not. Other aims included investigation of possible predictors and associated factors with remission and outcome. Method The study prospectively investigated a group of 56 patients with onset of psychosis during childhood or adolescence. Diagnosis made according to DSM-IV criteria and included; schizophrenia, psychotic disorder not otherwise specified and acute psychosis. Severity of psychosis was measured by PANSS. Measures of the outcome included; remission criteria of Andreasen et al 2005, the children's global assessment scale and educational level. Results Analysis of data was done for only 37 patients. Thirty patients diagnosed as schizophrenia and 7 with Psychotic disorder not otherwise specified. Mean duration of follow up was 38.4 +/- 16.9 months. At the end of the study, 6 patients (16.2% had one episode, 23(62.1% had multiple episodes and 8 (21.6% continuous course. Nineteen patients (51.4% achieved full remission, and only 11(29.7% achieved their average educational level for their age. Twenty seven percent of the sample had good outcome and 24.3% had poor outcome. Factors associated with non remission and poor outcome included gradual onset, low IQ, poor premorbid adjustment, negative symptoms at onset of the illness and poor adherence to drugs. Moreover, there was tendency of negative symptoms at illness start to predict poor outcome. Conclusion Some patients with early onset non affective psychosis can behave and function properly after few years from the start of the illness. Although remission is a difficult target in childhood psychosis, it is still achievable.

    The prevalence of diagnostic comorbidity between psychosis and anxiety disorders has been found to be considerable. Cognitive models of psychosis suggest that anxiety does not arise directly from positive symptoms of schizophrenia but rather from an individual interpretation of such experiences. In the United Kingdom, cognitive-behavioural therapy for psychosis (CBTp) has been recommended within clinical guidelines as a psychological treatment of choice for those diagnosed with schizophrenia....

  6. Thirty Days without a Bite: Wernicke’s Encephalopathy in a Patient with Paranoid Schizophrenia

    Langlois, Mélanie; Doré, Marie-Claire; Laforce, Robert

    2016-01-01

    Wernicke’s Encephalopathy (WE) is a preventable neurologic condition characterized by altered mental status, ophthalmoplegia, and ataxia. Although historically associated with alcoholism, a few authors have described WE in patients with non-alcohol related psychiatric disorders. We report herein the case of a 36-year-old young man with paranoid schizophrenia who was brought to hospital for confusion and difficulties with his vision. His roommate said he had gone about thirty days without eating ‘…because he was on a slimming cure’. History and physical examination suggested WE as a result of isolation and poor diet leading to nutritional deficiency. This was confirmed by brain magnetic resonance imaging showing classic thalamic, mammillary bodies and brainstem lesions. Of note, his cognitive profile was far more heterogeneous than what had classically been described in the literature and involved both cortical and subcortical pathology, generating memory but also significant executive deficits. Intravenous treatment with thiamine was given and our patient showed mild improvements in visual acuity and nystagmus. However, persistent cognitive and physical disabilities consistent with Korsakoff syndrome remained, and he now lives in a supervised home. This case illustrates the tragic consequences of nutritional deficiencies in a patient with paranoid schizophrenia. The threshold to suspect WE in schizophrenic patients should be lowered and in doubt prophylactic parenteral thiamine should be administered. PMID:27088109

  9. Are Specific Early-Life Adversities Associated With Specific Symptoms of Psychosis?: A Patient Study Considering Just World Beliefs as a Mediator.

    Wickham, Sophie; Bentall, Richard

    2016-08-01

    Epidemiological studies have suggested that there may be associations between specific adversities and specific psychotic symptoms. There is also evidence that beliefs about justice may play a role in paranoid symptoms. In this study, we determined whether these associations could be replicated in a patient sample and whether beliefs about a just world played a specific role in the relationship between adversity and paranoia. We examined associations between childhood trauma, belief in justice, and paranoia and hallucinatory experiences in 144 individuals: 72 individuals with a diagnosis of schizophrenia spectrum disorders and 72 comparison controls. There was a dose-response relationship between cumulative trauma and psychosis. When controlling for comorbidity between symptoms, childhood sexual abuse predicted hallucinatory experiences, and experiences of childhood emotional neglect predicted paranoia. The relationship between neglect and paranoia was mediated by a perception of personal injustice. The findings replicate in a patient sample previous observations from epidemiological research.

  12. Insight dimensions and cognitive function in psychosis: a longitudinal study

    Peralta Victor

    2006-05-01

    Full Text Available Abstract Background It has been reported that lack of insight is significantly associated with cognitive disturbance in schizophrenia. This study examines the longitudinal relationships between insight dimensions and cognitive performance in psychosis. Methods Participants were 75 consecutively admitted inpatients with schizophrenia, affective disorder with psychotic symptoms or schizoaffective disorder. Assessments were conducted at two time points during the study: at the time of hospital discharge after an acute psychotic episode and at a follow-up time that occurred more than 6 months after discharge. A multidimensional approach of insight was chosen and three instruments for its assessment were used: the Scale to Assess Unawareness of Mental Disorder (SUMD, three items concerning insight on the Assessment and Documentation in Psychopathology (AMDP system and the Insight and Treatment Attitudes Questionnaire. The neuropsychological battery included a wide range of tests that assessed global cognitive function, attention, memory, and executive functions. Results After conducting adequate statistical correction to avoid Type I bias, insight dimensions and cognitive performance were not found to be significantly associated at cross-sectional and longitudinal assessments. In addition, baseline cognitive performance did not explain changes in insight dimensions at follow-up. Similar results were found in the subset of patients with schizophrenia (n = 37. The possibility of a Type II error might have increased due to sample attrition at follow-up. Conclusion These results suggest that lack of insight dimensions and cognitive functioning may be unrelated phenomena in psychosis.

  16. Psychosis and violence: stories, fears, and reality.

    Taylor, Pamela J

    2008-10-01

    Individuals with psychosis are often feared. In fact, they are themselves likely to be victims of violence; however, the main aim of this review is to provide an overview of the evidence on relations between psychosis and violence to others. The terms psychosis and violence were used in a literature search limited to the Cochrane Library and PubMed, a manual search of 8 journals, and a follow-up of additional references in the articles found. The overview draws on new empirical data and major reviews. Almost all sound epidemiologic data on psychosis and violence dates from 1990. There is consistency on a small but significant relation between schizophrenia and violent acts. Since then there has also been movement toward understanding the nature of associations and progress on strategies for managing individuals who have psychosis and are violent. Public fears about individuals with psychotic illnesses are largely unfounded, although there would be benefit in greater attention to the safety of those in their close social circle. The task for the next 10 years must be the development and application of knowledge to improve specific treatments-that is, interventions that go beyond holding and caring to bring about substantial change.

    Schizophrenia is a clinically and genetically heterogeneous disorder of unknown etiology. PDLIM5 variants have been linked to schizophrenia and other related neuropsychiatric disorders and upregulated in the brain of schizophrenia patients suggesting a possible pathogenic role in disease progression. The aim of this study is to examine the potential association of schizophrenia in Emirati patients with previously reported variants in PDLIM5, PICK1, NRG3 or DISC1 genes. Consequently, we found a secondary association between PDLIM5 variants and the paranoid subtype of schizophrenia in Emirati Arabs suggesting that PDLIM5 may represent a determinate/marker for schizophrenia subtype specification. However, no associations were found with variants in PICK1, NRG3 or DISC1 genes. PMID:26925374

Each subgroup was further subdivided according to type of treatment into r (risperidone and h (haloperidol. Healthy male subjects (37 were subdivided into healthy khat-chewer as positive controls (HKc, n=17 and healthy non-khat-chewer as negative controls (HNKc, n=20. Plasma dopamine, 3,4-dihydroxyphenylacetic acid (DOPAC, homovanillic acid, 5-hydroxytryptamine (serotonin, 5-hydroxyindoleacetic acid, epinephrine, and norepinephrine were estimated.Results: ANOVA and post hoc analysis showed that dopamine was illustrating significant elevation in all khat chewing groups. DOPAC was illustrating significant decrease in all khat chewing groups with an interesting outcome showing significant increase in DOPAC in SNKcr group due to risperidone effect. Homovanillic acid, serotonin, hydroxyindoleacetic acid, and norepinephrine were illustrating significant elevations in all khat chewing groups. Epinephrine was illustrating significant elevation in all chewers than non-chewers groups. Unexpected significant decrease in epinephrine in the SNKcr group indicated that risperidone drug is decreasing epinephrine through indirect mechanism involving calcium.Conclusion: Khat chewing in schizophrenic patients is contraindicated because it aggravates the disease symptoms, attenuates all used treatment medications, and deteriorates all biochemical markers of the patients.

  20. A study of theory of mind in paranoid schizophrenia: A theory or many theories?

    PeterB.Scherzer

    2012-11-01

    Full Text Available Social cognitive psychologists (Frith, 1992; Hardy-Baylé et al, 2003 sought to explain the social problems and clarify the clinical picture of schizophrenia by proposing a model that relates many of the symptoms to a problem of metarepresentation i.e. theory of mind (ToM. Given the differences in clinical samples and results between studies, and considering the wide range of what is considered to constitute ToM, the question is, is there a core function, or is ToM multifaceted with dissociable facets? If there are dissociable dimensions or facets which are affected in patients with paranoid schizophrenia? To answer these questions, a group of 21 individuals diagnosed with paranoid schizophrenia and 29 non-clinical control subjects, were tested on a battery of five different measures of theory of mind. The results confirmed that there was little difference in specificity of three of the tests in distinguishing between the clinical and non-clinical group, but there were important differences in the shared variance between the tests. Further analyses hint at two dimensions although a single factor with the same variance and the same contributing weights in both groups could explain the results. The deficits related to the attribution of cognitive and affective states to others inferred from available verbal and non-verbal information. Further analyses revealed incorrect attributions of mental states including the attribution of threatening intentions to others non-interpretative responses and incomplete answers, depending on the test of theory of mind.

  1. First Aid Recommendations for Psychosis: Using the Delphi Method to Gain Consensus Between Mental Health Consumers, Carers, and Clinicians

    Langlands, Robyn L.; Jorm, Anthony F.; Kelly, Claire M.; Kitchener, Betty A.

    2008-01-01

    Background: Members of the general public often lack the knowledge and skills to intervene effectively to help someone who may be developing a psychotic illness before appropriate professional help is received. Methods: We used the Delphi method to determine recommendations on first aid for psychosis. An international panel of 157 mental health consumers, carers, and clinicians completed a 146-item questionnaire about how a member of the public could help someone who may be experiencing psychosis. The panel members rated each questionnaire item according to whether they believed the statement should be included in the first aid recommendations. The results were analyzed by comparing consensus rates across the 3 groups. Three rounds of ratings were required to consolidate consensus levels. Results: Eighty-nine items were endorsed by ≥80% of panel members from all 3 groups as essential or important for psychosis first aid. These items were grouped under the following 9 headings: how to know if someone is experiencing psychosis; how to approach someone who may be experiencing psychosis; how to be supportive; how to deal with delusions and hallucinations; how to deal with communication difficulties; whether to encourage the person to seek professional help; what to do if the person does not want help; what to do in a crisis situation when the person has become acutely unwell; what to do if the person becomes aggressive. Conclusions: These recommendations will improve the provision of first aid to individuals who are developing a psychotic disorder by informing the content of training courses. PMID:17768307

One patient exhibited severe psychomotor agitation, heteroaggressiveness, auditory and visual hallucinations as well as severe paranoid and mystic delusions. The other patient had psychomotor agitation, depersonalization, derealization, severe anxiety and deluded that he was losing his memory. Both patients had to be taken to the casualty room. After interruption of TPM in one patient and reduction of dose in the other, a full remission of the psychotic symptoms was obtained without the need of antipsychotic drugs. Clinicians should be aware of the possibility of development of acute psychotic symptoms in patients undergoing TPM treatment.Relatamos dois pacientes epilépticos que manifestaram quadro psicótico agudo induzido por topiramato (TPM.

  3. WELLFOCUS PPT: Modifying positive psychotherapy for psychosis.

    Riches, Simon; Schrank, Beate; Rashid, Tayyab; Slade, Mike

    2016-03-01

    Positive psychotherapy (PPT) is an established psychological intervention initially validated with people experiencing symptoms of depression. PPT is a positive psychology intervention, an academic discipline that has developed somewhat separately from psychotherapy and focuses on amplifying well-being rather than ameliorating deficit. The processes targeted in PPT (e.g., strengths, forgiveness, gratitude, savoring) are not emphasized in traditional psychotherapy approaches to psychosis. The goal in modifying PPT is to develop a new clinical approach to helping people experiencing psychosis. An evidence-based theoretical framework was therefore used to modify 14-session standard PPT into a manualized intervention, called WELLFOCUS PPT, which aims to improve well-being for people with psychosis. Informed by a systematic review and qualitative research, modification was undertaken in 4 stages: qualitative study, expert consultation, manualization, and stake-holder review. The resulting WELLFOCUS PPT is a theory-based 11-session manualized group therapy. PMID:25961372

  4. Does "ICU psychosis" really exist?

    Justic, M

    2000-06-01

    In summary, ICU psychosis does not develop in all patients. Instead, many patients are at risk for hypoactive, hyperactive, or mixed hypoactive and hyperactive delirium. Prevention of delirium should always be foremost, including recognition of patients at high risk, minimal use of causative medications, and treatment of physiological conditions that are often unrelated to a patient's admitting diagnosis. When prevention fails, early diagnosis and treatment can make a marked difference in patients' outcomes. The potential adverse outcomes of delirium are well documented. These include increased mortality; increased length of stay; reduced level of functioning in the elderly, which often leads to placement in a nursing home; and stress response syndrome after hospitalization. The value of nursing in preventing delirium is evident when nurses apply their knowledge of potential causes and develop strategies to avoid these causes in their patients. Nurses provide early detection and coordinate with other members of the healthcare team to initiate a plan of care that includes prompt treatment of delirium to reduce the signs and symptoms, duration, and potential adverse sequelae of this disorder. Nursing interventions are designed to enhance patients' cognitive status, sense of security, safety, and comfort. Nurses are instrumental in providing appropriate choices, doses, and administration of medications and in recognizing side effects. Use of medications ordered to treat delirium is often left to nurses' discretion because the orders specify that the drugs should be given as needed. Finally, nurses are the ones who recognize the need for additional assistance via psychiatric consultations or for more intensive observation and management of patients to ensure quality care.

    Full Text Available Animal models have become indispensible tools for discovering new medicines and in the analysis of multitude of causes, bio-markers and pathophysiological changes, which bring about symptoms characteristics of a specific disorder. One of the biggest challenges in discovering medicines for psychosis is to find an appropriate animal model of this illness possessing fair face validity, construct validity, and predictive validity. We had explained in detail behavioral models of psychosis in our previous article. In the present review article, the authors have described various non-behavioral models such as pharmacological models (administering specific chemicals, genetic models (through genetic manipulation, lesion models (lesion of selected brain parts and neuro-developmental models employed for screening anti-psychotic agents. All these animal models imitate schizophrenic defects in some manner. Traditionally, pharmacological models (drug/chemical-induced psychosis were the most widely used. These models involve the manipulation of dopaminergic, glutamatergic, serotonergic, or GABA-ergic systems. In Lesion models, selected area of an animal's brain is damaged, to induce psychosis-like symptoms. Genetic factors also play a prominent role in many psychiatric disorders and numerous putative candidate genes have been identified. Neurodevelopmental models are based on the fact that schizophrenia can be caused due to prenatal exposure to certain viruses. The animals usually employed for the development of these models include rats, mice, and primates. The specific animal models developed within these frameworks are described in this review article.

  8. Childhood and later life stressors and psychosis

    Leslie J. Roper

    2015-12-01

    Full Text Available The etiology of psychosis consists of a complex integration of several risk factors including genetic vulnerability, adverse life events and trauma, and substance use. This review discusses the current theories of the genesis of psychosis, with an emphasis on the importance of Adverse Childhood Experiences (ACEs and later life events. ACEs in particular have a profound impact on an individual’s health later in life; and specifically, those who have experienced ACEs are at an increased risk for psychosis. In addition, stressful life events later in life may be relevant for onset and relapse of psychotic episodes. Associations between types of life adversity and specific symptomatology of a psychotic episode have also been suggested. A multi-factorial approach is suggested for linking genetic and environmental contributors to the onset of psychosis. This approach may have an advantage over a purely bio-medical model by focusing less on disability and more on underlying contributors that may be responsive to intervention.

  9. Validation of the Excited Component of the Positive and Negative Syndrome Scale (PANSS-EC in a naturalistic sample of 278 patients with acute psychosis and agitation in a psychiatric emergency room

    2011-03-01

    Full Text Available Abstract Background Despite the wide use of the Excited Component of the Positive and Negative Syndrome Scale (PANSS-EC in a clinical setting to assess agitated patients, a validation study to evaluate its psychometric properties was missing. Methods Data from the observational NATURA study were used. This research describes trends in the use of treatments in patients with acute psychotic episodes and agitation seen in emergency departments. Exploratory principal component factor analysis was performed. Spearman's correlation and regression analyses (linear regression model as well as equipercentile linking of Clinical Global Impression of Severity (CGI-S, Agitation and Calmness Evaluation Scale (ACES and PANSS-EC items were conducted to examine the scale's diagnostic validity. Furthermore, reliability (Cronbach's alpha and responsiveness were evaluated. Results Factor analysis resulted in one factor being retained according to eigenvalue ≥1. At admission, the PANSS-EC and CGI-S were found to be linearly related, with an average increase of 3.4 points (p Conclusions The factorial analyses confirm the unifactorial structure of the PANSS-EC subscale. The PANSS-EC showed a strong linear correlation with rating scales such as CGI-S and ACES. PANSS-EC has also shown an excellent capacity to detect real changes in agitated patients.

  11. Unravelling psychosis: psychosocial epidemiology, mechanism, and meaning.

    Bebbington, Paul

    2015-04-25

    This paper reviews a revolution in our understanding of psychosis over the last 20 years. To a major extent, this has resulted from a process of cross-fertilization between psychosocial epidemiology and cognitive behavior therapy for psychosis (CBT-p). This encouraged complementary strategies for the acquisition and analysis of data. These include the use of a range of dependent variables related to psychosis, and the exploitation of data from cross-sectional and longitudinal epidemiological surveys, virtual reality experiments, experience sampling methodology, and treatment trials. The key element is to investigate social and psychological measures in relation to each other. This research has confirmed the role of the external social world in the development and persistence of psychotic disorder. In addition, several psychological drivers of psychotic experiences have been identified. There is now persuasive evidence that the influence of social factors in psychosis is significantly mediated by non-psychotic symptoms, particularly mood symptoms and other attributes of affect such as insomnia. Psychotic symptoms are also driven by reasoning biases such as jumping to conclusions and belief inflexibility, though little is known about social influences on such biases. It is now clear that there are many routes to psychosis and that it takes many forms. Treatment of all kinds should take account of this: the dependence of CBT-p on a detailed initial formulation in terms of psychological processes and social influences is an example of the required flexibility. Individual mediators are now being targeted in specific forms of CBT-p, with good effect. This in turn corroborates the hypothesized role of non-psychotic symptoms in mediation, and attests to the power of the approaches described. PMID:26120255

  12. A case of Hashimoto`s encephalopathy presenting with seizures and psychosis

    Min-Joo Lee

    2012-03-01

    Full Text Available Hashimoto’s encephalopathy (HE is a rare, poorly understood, autoimmune disease characterized by symptoms of acute or subacute encephalopathy associated with increased anti-thyroid antibody levels. Here, we report a case of a 14-year-old girl with HE and briefly review the literature. The patient presented with acute mental changes and seizures, but no evidence of infectious encephalitis. In the acute stage, the seizures did not respond to conventional antiepileptic drugs, including valproic acid, phenytoin, and topiramate. The clinical course was complicated by the development of acute psychosis, including bipolar mood, insomnia, agitation, and hallucinations. The diagnosis of HE was supported by positive results for antithyroperoxidase and antithyroglobulin antibodies. Treatment with methylprednisolone was effective; her psychosis improved and the number of seizures decreased. HE is a serious but curable, condition, which might be underdiagnosed if not suspected. Anti-thyroid antibodies must be measured for the diagnosis. HE should be considered in patients with diverse neuropsychiatric manifestations.

  18. Childhood trauma and psychosis - what is the evidence?

    Schäfer, Ingo; Fisher, Helen L.

    2011-01-01

    In the last decade, a substantial number of population-based studies have suggested that childhood trauma is a risk factor for psychosis. In several studies, the effects held after adjusting for a wide range of potentially confounding variables, including genetic liability for psychosis. Less is known about the mechanisms underlying the association between childhood trauma and psychosis. Possible pathways include relationships between negative perceptions of the self, negative affect, and psy...

  1. The use of videoconferencing with patients with psychosis: a review of the literature

    Kobak Kenneth A

    2011-04-01

    Full Text Available Abstract Videoconferencing has become an increasingly viable tool in psychiatry, with a growing body of literature on its use with a range of patient populations. A number of factors make it particularly well suited for patients with psychosis. For example, patients living in remote or underserved areas can be seen by a specialist without need for travel. However, the hallmark symptoms of psychotic disorders might lead one to question the feasibility of videoconferencing with these patients. For example, does videoconferencing exacerbate delusions, such as paranoia or delusions of reference? Are acutely psychotic patients willing to be interviewed remotely by videoconferencing? To address these and other issues, we conducted an extensive review of Medline, PsychINFO, and the Telemedicine Information Exchange databases for literature on videoconferencing and psychosis. Findings generally indicated that assessment and treatment via videoconferencing is equivalent to in person and is tolerated and well accepted. There is little evidence that patients with psychosis have difficulty with videoconferencing or experience any exacerbation of symptoms; in fact, there is some evidence to suggest that the distance afforded can be a positive factor. The results of two large clinical trials support the reliability and effectiveness of centralized remote assessment of patients with schizophrenia.

  2. [Wernicke encephalopathy and Korsakoff's psychosis: clinical-pathophysiological correlation, diagnostics and treatment].

    Sivolap, Iu P; Damulin, I V

    2013-01-01

    Wernicke's encephalopathy and Korsakoff's psychosis are severe unfavorable forms of alcoholic brain damage with poor prognosis. Thiamine deficiency represents a common cause of both diseases. In many cases, Korsakoff's psychosis develops in the outcome of Wernicke's encephalopathy, which, along with the general etiology, lets talk about a single disease - Wernicke-Korsakoff syndrome, acute (usually reversible) stage of which is Wernicke's encephalopathy and a chronic one (often irreversible) is Korsakoff psychosis. The dramatic paradox of Wernicke's encephalopathy is that in most cases it is difficult to detect, but early diagnosed cases are quite easy to cure. Unrecognized and therefore go untreated Wernicke's encephalopathy is a serious threat to the health and lives of patients, worsens the processes of brain aging and increases the risk of Alzheimer's disease in later life. The basic approach to the treatment of Wernicke-Korsakoff syndrome is long-term parenteral administration of thiamine, often in high doses. As an adjuvant means of therapy memantine is considered.

  3. Gray matter volumetric abnormalities associated with the onset of psychosis

    Wi Hoon eJung

    2012-12-01

    Full Text Available Patients with psychosis display structural brain abnormalities in multiple brain regions. The disorder is characterized by a putative prodromal period called ultra-high-risk (UHR status, which precedes the onset of full-blown psychotic symptoms. Recent studies on psychosis have focused on this period. Neuroimaging studies of UHR individuals for psychosis have revealed that the structural brain changes observed during the established phases of the disorder are already evident prior to the onset of the illness. Moreover, certain brain regions show extremely dynamic changes during the transition to psychosis. These neurobiological features may be used as prognostic and predictive biomarkers for psychosis. With advances in neuroimaging techniques, neuroimaging studies focusing on gray matter abnormalities provide new insights into the pathophysiology of psychosis, as well as new treatment strategies. Some of these novel approaches involve antioxidants administration, because it is suggested that this treatment may delay the progression of UHR to a full-blown psychosis and prevent progressive structural changes. The present review includes an update on the most recent developments in early intervention strategies for psychosis and potential therapeutic treatments for schizophrenia. First, we provide the basic knowledge of the brain regions associated with structural abnormalities in individuals at UHR. Next, we discuss the feasibility on the use of magnetic resonance imaging (MRI-biomarkers in clinical practice. Then, we describe potential etiopathological mechanisms underlying structural brain abnormalities in prodromal psychosis. Finally, we discuss the potentials and limitations related to neuroimaging studies in individuals at UHR.

  4. [Psychosis and grammatical reality. Preliminary to an axiomatic system].

    Schmidt, P

    1981-05-01

    This paper is elaborated in the same order of those who developpe the idea that, Psychosis is pleaded as an alibi of a totalitarian reality (Psychosis alibi). So it may allow to disengage the evolution of the Psychiatry outside of the anti-psychiatry ideologies. The main subject of this work, is to analyse the gap between the Reality which includes the psychosis as a part of herself (Psychosis as disease). On the second hand the Reality of the psychosis from the psycho-pathologic point of view (delirium, hallucinations, autism, etc...). Considering the importance of the formal grammatical functions in the linguistic matter to site the reference to the reality according to the rules of the communication and the oral expression; so we propose a grammatical analysis. Two parts are distinguishable in this work. The first part concerns a review of languages proposed in different psychiatric "theorization" established previously about mental disorder. So it could be considered that the psychosis is the one who "speaks" the psychiatry. The second part concerns an abstract of the "semiotiques" studies by which we can tackle the psychosis with a scientific language: The Psychiatric "speaking" the psychosis not the opposite. This way of analyse allows to realize the modifications in the part of both protagonists in the game. By the same way, it authorizes to introduce the psychiatry from the axiomatic point of view, allowing a self-contained definition as a branch of the medicine, and disengaging his subject: The psychosis; as a syntactic subject.

  5. Pathways from cannabis to psychosis: a review of the evidence

    Jonathan K Burns

    2013-10-01

    Full Text Available The nature of the relationship between cannabis use and psychosis is complex and remains unclear. Researchers and clinicians remain divided regarding key issues such as whether or not cannabis is an independent cause of psychosis and schizophrenia. This paper reviews the field in detail, examining questions of causality, the neurobiological basis for such causality and for differential inter-individual risk, the clinical and cognitive features of psychosis in cannabis users, and patterns of course and outcome of psychosis in the context of cannabis use. The author proposes two major pathways from cannabis to psychosis based on a differentiation between early-initiated lifelong cannabis use and a scenario where vulnerable individuals without a lifelong pattern of use consume cannabis over a relatively brief period of time just prior to psychosis onset. Additional key factors determining the clinical and neurobiological manifestation of psychosis as well as course and outcome in cannabis users include: underlying genetic and developmental vulnerability to schizophrenia-spectrum disorders; and whether or not cannabis use ceases or continues after the onset of psychosis. Finally, methodological guidelines are presented for future research aimed at both elucidating the pathways that lead from cannabis to psychosis and clarifying the long-term outcome of the disorder in those who have a history of using cannabis.

  6. Psychosis in Patients with Systemic Lupus Erythematosus

    Raghavendra B Nayak

    2012-01-01

    Full Text Available Neuropsychiatric manifestations in systemic lupus erythematosus (SLE are common; however, psychosis per se is bit uncommon. They may be cognitive deficit, lupus headache, psychoses, seizures, peripheral neuropathy, and cerebrovascular events. Psychiatric symptoms in SLE can be functionally independent psychiatric disorders. It can be due to drugs (steroids used for SLE or secondary to SLE because of its brain involvement, which is termed as neuropsychiatric systemic lupus erythematosus (NPSLE. No single clinical, laboratory, neuropsychological, and imaging test can be used to differentiate NPSLE from non-NPSLE patients with similar neuropsychiatric manifestations. Presently we are discussing about three cases of SLE with psychosis and which had different clinical presentation. The present reports also depict the approach to case differential diagnosis and management of the same.

  7. Cognitive Behavioral Therapy in Prodromal Psychosis

    Addington, Jean; Marshall, Catherine; French, Paul

    2014-01-01

    There is a strong impetus in the psychosis research field to develop interventions that aim to prevent the onset of psychotic disorders. Over the past 15 years there has been a tremendous development in the work aimed at understanding the pre-psychotic period. More recently there has been a focus on developing and testing treatments both pharmacological and psychological that could potentially prevent or delay the onset of psychosis. One of the psychological treatments that has received the most attention is cognitive behavioral therapy (CBT). Relatively few trials have been completed and this paper reviews the existing trials. Implications of these trials for the treatment of this early phase as well as for designing future studies are discussed. PMID:22239588

  8. Gone to Pot - A Review of the Association between Cannabis and Psychosis

    Rajiv eRadhakrishnan

    2014-05-01

    Full Text Available Cannabis is the most commonly used illicit drug worldwide, with approximately 5 million daily users worldwide. Emerging evidence supports a number of associations between cannabis and psychosis/psychotic disorders, including schizophrenia. These associations based on case-studies, surveys, epidemiological studies, and experimental studies indicate that cannabinoids can produce acute, transient effects; acute, persistent effects as well as delayed, persistent effects that recapitulate the psychopathology and psychophysiology seen in psychotic illness such as schizophrenia. Acute exposure to both cannabis and synthetic cannabinoids (Spice/ K2 can produce a full range of transient psychotomimetic symptoms, cognitive deficits, and psychophysiological abnormalities that bear a striking resemblance to symptoms of schizophrenia. In individuals with an established psychotic disorder, cannabinoids can exacerbate symptoms, trigger relapse, and have negative consequences on the course of the illness. Several factors appear to moderate these associations, including family history, genetic factors, history of childhood abuse, and the age at onset of cannabis use. Exposure to cannabinoids in adolescence confers a higher risk for psychosis outcomes in later life and the risk is dose-related. Individuals with polymorphisms of COMT and AKT1 genes may be at increased risk for psychotic disorders in association with cannabinoids, as are individuals with a family history of psychotic disorders or a history of childhood trauma. The relationship between cannabis and schizophrenia fulfills many but not all of the standard criteria for causality, including temporality, biological gradient, biological plausibility, experimental evidence, consistency, and coherence. At the present time, the evidence indicates that cannabis may be a component cause in the emergence of psychosis, and warrants serious consideration from the point of view of public health policy.

  10. [Adolescent psychosis, can neuroscience improve prediction?].

    Holzer, L; Halfon, O; Jaugey, L

    2008-04-01

    Developments in the field of neuroscience have created a high level of interest in the subject of adolescent psychosis, particularly in relation to prediction and prevention. As the medical practice of adolescent psychosis and its treatment is characterised by a heterogeneity which is both symptomatic and evolutive, the somewhat poor prognosis of chronic development justifies the research performed: apparent indicators of schizophrenic disorders on the one hand and specific endophenotypes on the other are becoming increasingly important. The significant progresses made on the human genome show that the genetic predetermination in current psychiatric pathologies is complex and subject to moderating effects and there is therefore significant potential for nature-nurture interactions (between the environment and the genes). The road to be followed in researching the phenotypic expression of a psychosis gene is long and winding and is susceptible to many external influences at various levels with different effects. Neurobiological, neurophysiological, neuropsychological and neuroanatomical studies help to identify endophenotypes, which allow researchers to create identifying "markers" along this winding road. The endophenotypes could make it possible to redefine the nosological categories and enhance understanding of the physiopathology of schizophrenia. In a predictive approach, large-scale retrospective and prospective studies make it possible to identify risk factors, which are compatible with the neurodevelopmental hypothesis of schizophrenia. However, the predictive value of such markers or risk indicators is not yet sufficiently developed to offer a reliable early-detection method or possible schizophrenia prevention measures. Nonetheless, new developments show promise against the background of a possible future nosographic revolution, based on a paradigm shift. It is perhaps on the basis of homogeneous endophenotypes in particular that we will be able to

    Dhanya Raveendranathan

    2012-01-01

    Full Text Available Obsessive compulsive disorder (OCD is commonly regarded as a disorder with good insight. However, it has now been recognized that insight varies in these patients. Pathological beliefs seem to lie on a continuum of insight, with full insight at one end and delusion at the other. This can indeed pose a considerable challenge, especially in a scenario where the phenomenon is difficult to discern. We report a case of OCD, which was initially diagnosed as psychosis.

    SUMMARY A five-year follow-up study of 38 patients with ‘psychosis not otherwise specified’ revealed that diagnostic change occurred in 34.2% of the patients. 15.8% of the patients developed schizophrenia and 18.4% developed affective disorders. The initial diagnosis was retained in 65.8% of the patients. The onset of the illness was acute in patients from rural background and this is statistically significant. 42% of the patients presented only catatonic signs, of which nearly 70% showed ful...

  16. Psychosis during peginterferon-alpha2a and ribavirin therapy: case report

    Lucas C. Quarantini

    2006-12-01

    Full Text Available Pegylated Interferon-alpha, combined with ribavirin, gives high sustained virological response in patients with hepatitis C virus, an important public health problem and one of the most frequent chronic infectious diseases worldwide. Though it has therapeutic benefits, treatment with IFN-alpha may be complicated by various side effects, especially symptoms of major depression and acute mania. Psychosis is a rare side effect, and its management usually includes discontinuation of IFN-alpha. We report a case of psychotic disorder that occurred during therapy with pegylated Interferon-alpha given associated with ribavirin. After good response to psychiatric treatment, it became possible to finish the anti-viral therapy.

  17. Intrinsic motivation and amotivation in first episode and prolonged psychosis.

    Luther, Lauren; Lysaker, Paul H; Firmin, Ruth L; Breier, Alan; Vohs, Jenifer L

    2015-12-01

    The deleterious functional implications of motivation deficits in psychosis have generated interest in examining dimensions of the construct. However, there remains a paucity of data regarding whether dimensions of motivation differ over the course of psychosis. Therefore, this study examined two motivation dimensions, trait-like intrinsic motivation, and the negative symptom of amotivation, and tested the impact of illness phase on the 1) levels of these dimensions and 2) relationship between these dimensions. Participants with first episode psychosis (FEP; n=40) and prolonged psychosis (n=66) completed clinician-rated measures of intrinsic motivation and amotivation. Analyses revealed that when controlling for group differences in gender and education, the FEP group had significantly more intrinsic motivation and lower amotivation than the prolonged psychosis group. Moreover, intrinsic motivation was negatively correlated with amotivation in both FEP and prolonged psychosis, but the magnitude of the relationship did not statistically differ between groups. These findings suggest that motivation deficits are more severe later in the course of psychosis and that low intrinsic motivation may be partially independent of amotivation in both first episode and prolonged psychosis. Clinically, these results highlight the importance of targeting motivation in early intervention services. PMID:26386901

  3. Citrin deficiency: A treatable cause of acute psychosis in adults

    Sunita Bijarnia-Mahay

    2015-01-01

    Full Text Available Citrin deficiency is an autosomal recessive genetic disorder caused by a defect in the mitochondrial aspartate/glutamate antiporter, citrin. The disorder manifests either as neonatal intra-hepatic cholestasis or occurs in adulthood with recurrent hyperammonemia and neuropsychiatric disturbances. It has a high prevalence in the East Asian population, but is actually pan-ethnic. We report the case of a 26-year-old male patient presenting with episodes of abnormal neuro-psychiatric behavior associated with hyperammonemia, who was diagnosed to be having citrin deficiency. Sequencing of the SLC25A13 gene revealed two novel mutations, a single base pair deletion, c. 650delT (p.Phe217SerfsFNx0133 in exon 7, and a missense mutation, c. 869T>C (p.Ile290Thr in exon 9. Confirmation of the diagnosis allowed establishment of the appropriate management. The latter is an essential pre-requisite for obtaining a good prognosis as well as for family counseling.

Particularly, corpus callosum lesions seem to play a role in the change of patients’ behavior. We present a case of a sudden psychotic attack presumably due to a hemorrhagic cavernous angioma of the corpus callosum, which was surgically removed with complete resolution of symptoms. Although a developmental defect like agenesis or lipoma is present in the majority of these cases, a growing lesion of the corpus callosum can rarely be the primary cause. Since it is potentially possible to cure these patients, clinicians should be aware of this association.

    are largely uninvestigated, but may identify subgroups with different intellectual trajectories. Eighty-nine first-episode psychosis patients were investigated on IQ at baseline and at 10-years follow-up. Total time in psychosis was defined as two separate variables; Duration of psychosis before start...... of treatment (i.e. duration of untreated psychosis: DUP), and duration of psychosis after start of treatment (DAT). The sample was divided in three equal groups based on DUP and DAT, respectively. To investigate if diagnosis could separate IQ-trajectories beyond that of psychotic duration, two...... diagnostic categories were defined: core versus non-core SSDs. No significant change in IQ was found for the total sample. Intellectual course was not related to DUP or stringency of diagnostic category. However, a subgroup with long DAT demonstrated a significant intellectual decline, mainly associated with...

    Anti-NMDA receptor (NMDAR) encephalitis is a recently identified autoimmune disorder with prominent psychiatric symptoms. Patients usually present with acute behavioral change, psychosis, catatonic symptoms, memory deficits, seizures, dyskinesias, and autonomic instability. In female patients an ovarian teratoma is often identified. We describe a 32-year-old woman who presented with acute psychosis. Shortly after admission, she developed generalized seizures and deteriorated into a catatonic ...

    Schizophrenia paranoid is a chronic psychotic disorder which has a relapse. The data from the Medical Research of the Mental Hospital of North Sumatera stated that 65.8% of schizophrenia paranoid patients who were treated in 2013 had a relapse so that they had to be sent again to the hospital. The high rate of relapse is probably related to the medical compliance and family coping. The objective of the research was to analyze the influence of medical compliance and family coping on the preven...

  9. Demographic features and premorbid personality disorder traits in relation to age of onset and sex in paranoid schizophrenia.

    Skokou, Maria; Gourzis, Philippos

    2014-03-30

    Personality disorders in the premorbid period of schizophrenia and particularly in relation to age of onset and sex, seem to be a rather under-researched area. In the present study, 88 patients with paranoid schizophrenia were examined, regarding demographic characteristics and premorbid personality disorder traits, in order to investigate for differences in the premorbid period of the disease, in relation to age of onset and sex. Age cutoff points were set at personality disorder traits were retrospectively assessed by using the Structured Clinical Interview for DSM-IV-Patient Edition for Axis II disorders (SCID-II). Comparisons were performed by applying the two-tailed Wilcoxon rank-sum and the χ(2) statistical tests. Young onset patients were characterized by significantly higher proportion of urban birth, single status, more avoidant premorbid personality disorder traits, and less passive-aggressive premorbid personality disorder traits, than late onset counterparts. Differences were more prominently shown in men. Earlier age of onset seems to be associated to increased social inhibition and worse psychosocial adaptation in the premorbid period of paranoid schizophrenia. PMID:24495576

  10. SNP8NRG433E1006 NEUREGULIN-1 GENETIC VARIATION IN BATAKS ETHNIC WITH SCHIZOPHRENIA PARANOID AND HEALTHY CONTROL

    2014-05-01

    Full Text Available The neuregulin 1 (NRG1 gene which influences the development of white matter connectivity has been associated with schizophrenia. It influences neuronal migration, synaptogenesis, gliogenesis, neuron-glia communication, myelination, and neurotransmission in the brain and others. NRG1 is located in 8p13, and it is frequently replicated in schizphrenia. SNP8NRG433E1006 gene NRG1 is one of core at risk haplotype of schizphrenia. This study looked forward differences SNP8NRG433E1006 neuregulin 1 between Bataks ethnic with schizophrenia paranoid and Bataks ethnic healthy control. Methods: Batak ethnic with schizophrenia paranoid were recruited and interviewed with semi-structured MINI ICD-X to establish the diagnosis. All the eligible subjects were requested their permission for blood sampling. Healthy Batak ethnic were also recruited by mathcing the age and gender. The blood samples went through DNA isolation, Nested PCR, and DNA sequencing. Results: Ninety three subjects were recruited, but only 74 blood samples were succesfully sequenced. We found three types of polymorphisms, i.e. G/A allele at base pair (bp 76, G/T allele at bp 112, and deletion at bp 110 in Batak ethnic with schizophrenia. There were two kind sequences at bp 113-116 in Batak ethnics, and Batak ethnics with ATCG were at higher risk for having schizophrenia. This study support that NRG1 is a schizophrenia-susceptibility gene.

  11. It's All in the Rhythm: The Role of Cannabinoids in Neural Oscillations and Psychosis.

    Skosnik, Patrick D; Cortes-Briones, Jose A; Hajós, Mihály

    2016-04-01

    Evidence has accumulated over the past several decades suggesting that both exocannabinoids and endocannabinoids play a role in the pathophysiology of schizophrenia. The current article presents evidence suggesting that one of the mechanisms whereby cannabinoids induce psychosis is through the alteration in synchronized neural oscillations. Neural oscillations, particularly in the gamma (30-80 Hz) and theta (4-7 Hz) ranges, are disrupted in schizophrenia and are involved in various areas of perceptual and cognitive function. Regarding cannabinoids, preclinical evidence from slice and local field potential recordings has shown that central cannabinoid receptor (cannabinoid receptor type 1) agonists decrease the power of neural oscillations, particularly in the gamma and theta bands. Further, the administration of cannabinoids during critical stages of neural development has been shown to disrupt the brain's ability to generate synchronized neural oscillations in adulthood. In humans, studies examining the effects of chronic cannabis use (utilizing electroencephalography) have shown abnormalities in neural oscillations in a pattern similar to those observed in schizophrenia. Finally, recent studies in humans have also shown disruptions in neural oscillations after the acute administration of delta-9-tetrahydrocannabinol, the primary psychoactive constituent in cannabis. Taken together, these data suggest that both acute and chronic cannabinoids can disrupt the ability of the brain to generate synchronized oscillations at functionally relevant frequencies. Hence, this may represent one of the primary mechanisms whereby cannabinoids induce disruptions in attention, working memory, sensory-motor integration, and many other psychosis-related behavioral effects.

  12. Very Low-Dose Risperidone in First-Episode Psychosis: A Safe and Effective Way to Initiate Treatment

    Patrick D. McGorry

    2011-01-01

    Full Text Available Patients experiencing a first psychotic episode have high rates of extrapyramidal symptoms (EPSs when treated with the doses of neuroleptics used in multiepisode or chronic schizophrenia. There is some evidence that lower doses may be equally, if not more, effective but less toxic in this population. Here, we report the results of a biphasic open label trial designed to assess the efficacy, safety, and tolerability of low-dose (2–4 mg/day risperidone treatment in a group of 96 first-episode nonaffective psychosis patients. At the end of the trial, 62% of patients met the response criteria although approximately 80% had achieved a response at some time during the study. Reports of EPS remained low, and there were no dystonic reactions. We conclude that even at a dose of 2 mg/day, risperidone was highly effective in reducing acute symptomatology in a real world sample of young first-episode psychosis patients.

  13. Retrospective study on structural neuroimaging in first-episode psychosis.

    Coentre, Ricardo; Silva-Dos-Santos, Amilcar; Talina, Miguel Cotrim

    2016-01-01

    Background. No consensus between guidelines exists regarding neuroimaging in first-episode psychosis. The purpose of this study is to assess anomalies found in structural neuroimaging exams (brain computed tomography (CT) and magnetic resonance imaging (MRI)) in the initial medical work-up of patients presenting first-episode psychosis. Methods. The study subjects were 32 patients aged 18-48 years (mean age: 29.6 years), consecutively admitted with first-episode psychosis diagnosis. Socio-demographic and clinical data and neuroimaging exams (CT and MRI) were retrospectively studied. Diagnostic assessments were made using the Operational Criteria Checklist +. Neuroimaging images (CT and MRI) and respective reports were analysed by an experienced consultant psychiatrist. Results. None of the patients had abnormalities in neuroimaging exams responsible for psychotic symptoms. Thirty-seven percent of patients had incidental brain findings not causally related to the psychosis (brain atrophy, arachnoid cyst, asymmetric lateral ventricles, dilated lateral ventricles, plagiocephaly and falx cerebri calcification). No further medical referral was needed for any of these patients. No significant differences regarding gender, age, diagnosis, duration of untreated psychosis, in-stay and cannabis use were found between patients who had neuroimaging abnormalities versus those without. Discussion. This study suggests that structural neuroimaging exams reveal scarce abnormalities in young patients with first-episode psychosis. Structural neuroimaging is especially useful in first-episode psychosis patients with neurological symptoms, atypical clinical picture and old age. PMID:27257547

  14. The future of psychological therapies for psychosis.

    Garety, Philippa A

    2003-10-01

    The need for psychological therapies for psychosis is increasingly recognised. In recent years, two psychological approaches, cognitive behavioural therapy (CBT) and family interventions (FI), have emerged from among a range of psychological approaches as effective therapies with the strongest evidence base. The theoretical basis of these approaches, within a broader biopsychosocial stress-vulnerability framework, is described. The evidence of effectiveness, drawn from the results of recent systematic reviews of CBT and FI, is summarised. CBT is found to reduce symptoms and FI to reduce relapse, with some evidence of improvement in other outcomes for both approaches. Future directions for these therapies are considered, with particular emphasis on their role in early intervention services and relapse prevention. Promising newer applications of these approaches are also discussed, for example in work with people with a dual diagnosis of psychosis and substance misuse disorder. Finally, training and dissemination issues are addressed. It is emphasised that the integration of psychological therapies within comprehensive service provision is important. PMID:16946920

  15. Premorbid multivariate prediction of adult psychosis-spectrum disorder

    Schiffman, Jason; Kline, Emily; Jameson, Nicole D.;

    2015-01-01

    Premorbid prediction of psychosis-spectrum disorders has implications for both understanding etiology and clinical identification. The current study used a longitudinal high-risk for psychosis design that included children of parents with schizophrenia as well as two groups of controls (children...... whose parents had no mental illness, and children with at least one parent with a non-psychotic psychiatric diagnosis). Premorbid neurological factors and an indication of social function, as measured when participants were 10-13years of age, were combined to predict psychosis-spectrum disorders in...

  16. Avoidant Personality Disorder is a Separable Schizophrenia Spectrum Personality Disorder even when Controlling for the Presence of Paranoid and Schizotypal Personality Disorders

    Fogelson, D. L.; Nuechterlein, K. H.; Asarnow, R. A.; Payne, D. L.; Subotnik, K. L.; Jacobson, K.C.; Neale, M. C.; Kendler, K. S.

    2007-01-01

    It is unresolved whether avoidant personality disorder (APD) is an independent schizophrenia (Sz)-spectrum personality disorder (PD). Some studies find APD and social anxiety symptoms (Sxs) to be a separable dimension of psychopathology in relatives (Rels) of schizophrenics while other studies find avoidant Sxs to be correlated with schizotypal and paranoid Sxs.

    Reininghaus, Ulrich; Priebe, Stefan; Bentall, Richard P.

    2012-01-01

    Background: Psychiatric taxonomists have sometimes argued for a unitary psychosis syndrome and sometimes for a pentagonal model, including 5 diagnostic constructs of positive symptoms, negative symptoms, cognitive disorganization, mania, and depression. This continues to be debated in preparation for impending revisions of the Diagnostic and Statistical Manual of Mental Disorders and the International Classification of Diseases. We aimed to identify general and specific dimensions underlying ...

  18. Psychosis and the Control of Lucid Dreaming.

    Mota, Natália B; Resende, Adara; Mota-Rolim, Sérgio A; Copelli, Mauro; Ribeiro, Sidarta

    2016-01-01

    Dreaming and psychosis share important features, such as intrinsic sense perceptions independent of external stimulation, and a general lack of criticism that is associated with reduced frontal cerebral activity. Awareness of dreaming while a dream is happening defines lucid dreaming (LD), a state in which the prefrontal cortex is more active than during regular dreaming. For this reason, LD has been proposed to be potentially therapeutic for psychotic patients. According to this view, psychotic patients would be expected to report LD less frequently, and with lower control ability, than healthy subjects. Furthermore, psychotic patients able to experience LD should present milder psychiatric symptoms, in comparison with psychotic patients unable to experience LD. To test these hypotheses, we investigated LD features (occurrence, control abilities, frequency, and affective valence) and psychiatric symptoms (measure by PANSS, BPRS, and automated speech analysis) in 45 subjects with psychotic symptoms [25 with Schizophrenia (S) and 20 with Bipolar Disorder (B) diagnosis] versus 28 non-psychotic control (C) subjects. Psychotic lucid dreamers reported control of their dreams more frequently (67% of S and 73% of B) than non-psychotic lucid dreamers (only 23% of C; S > C with p = 0.0283, B > C with p = 0.0150). Importantly, there was no clinical advantage for lucid dreamers among psychotic patients, even for the diagnostic question specifically related to lack of judgment and insight. Despite some limitations (e.g., transversal design, large variation of medications), these preliminary results support the notion that LD is associated with psychosis, but falsify the hypotheses that we set out to test. A possible explanation is that psychosis enhances the experience of internal reality in detriment of external reality, and therefore lucid dreamers with psychotic symptoms would be more able to control their internal reality than non-psychotic lucid dreamers.

  1. Dynamic psychiatry and the treatment of anorexia psychosis.

    Silver, Ann-Louise S; White, Janice

    2011-01-01

    Dynamic psychotherapy of psychosis works through gradually diminishing terror, replacing this with a clearer and shared understanding of the patient's life history, its traumas and its strengths. It is diametrically opposed to our current push for efficiency and an assumption of an underlying brain disorder that responds to our current medications. Over the course of a long treatment, this patient became a scholar of psychoanalytic contributions to understanding psychosis and is now a philosopher of this field, developing an understanding of anorexia psychosis. She draws on the writings of Freud, Bion, Lacan, and Julian Jaynes, placing the core of psychosis not in primary process but in a preceding, non-self phase of development. She relates this individual development to the history of human development. PMID:21434743

  2. The Epidemiologic Evidence Linking Autoimmune Diseases and Psychosis

    Benros, Michael E; Eaton, William W; Mortensen, Preben B

    2014-01-01

    This review summarizes the epidemiologic evidence linking autoimmune diseases and psychosis. The associations between autoimmune diseases and psychosis have been studied for more than a half century, but research has intensified within the last decades, since psychosis has been associated with...... genetic markers of the immune system and with excess autoreactivity and other immune alterations. A range of psychiatric disorders, including psychosis, have been observed to occur more frequently in some autoimmune diseases, such as systemic lupus erythematosus and multiple sclerosis. Many autoimmune...... diseases involve multiple organs and general dysfunction of the immune system, which could affect the brain and induce psychiatric symptoms. Most studies have been cross-sectional, observing an increased prevalence of a broad number of autoimmune diseases in people with psychotic disorders. Furthermore...

  3. Complete remission of epileptic psychosis after temporal lobectomy: case report

    Marchetti Renato Luiz

    2001-01-01

    Full Text Available We report a case of a female patient with refractory complex partial seizures since 15 years of age, recurrent postictal psychotic episodes since 35 which evolved to a chronic refractory interictal psychosis and MRI with right mesial temporal sclerosis (MTS. After a comprehensive investigation (video-EEG intensive monitoring, interictal and ictal SPECT, and a neuropsychological evaluation including WADA test she was submitted to a right temporal lobectomy. Since then, she has been seizure-free with remission of psychosis, although with some persistence of personality traits (hiperreligiosity, viscosity which had been present before surgery. This case supports the idea that temporal lobectomy can be a safe and effective therapeutic measure for patients with MTS, refractory epilepsy and recurrent postictal epileptic psychosis or interictal epileptic psychosis with postictal exacerbation.

    Major self-mutilation (MSM) is a rare but catastrophic complication of severe mental illness. Most people who inflict MSM have a psychotic disorder, usually a schizophrenia spectrum psychosis. It is not known when in the course of psychotic illness, MSM is most likely to occur. In this study, the proportion of patients in first episode of psychosis (FEP) was assessed using the results of a systematic review of published case reports. Histories of patients who had removed an eye or a testicle,...

  6. Ten year neurocognitive trajectories in first-episode psychosis

    2013-10-01

    Conclusions: Main findings are long-term stability in neurocognitive functioning in first episode psychosis patients, with the exception of verbal memory in patients with psychotic relapse or non-remission early in the course of illness. We conclude that worsening of specific parts of cognitive function may be expected for patients with on-going psychosis, but that most patients should expect no change in cognitive performance during the first 10 years after being diagnosed.

    Introduction: Recent models of psychosis implicate stressful events in its etiology. However, while evidence has accumulated for childhood trauma, the role of adult life events has received less attention. Therefore, a review of the existing literature on the relationship between life events and onset of psychotic disorder/experiences is timely. Methods: A search was conducted using PsychInfo, Medline, Embase, and Web of Science to identify studies of life events and the onset of psychosis or...

  12. [Awareness of illness in affective psychosis].

    Jarosz, M; Poprawska, I

    1992-01-01

    On the basis of analyzed clinical material several observations were attempted which were related to the patients' awareness of one's own affective psychosis. It was discovered that patients with endogenous depression considered themselves to be ill, but only in relation to depression. They usually do not perceive in themselves any psychotic illness. It was noticed that in depression past achievements appeared to be foreign to the patients. This was described in among other terms as "emotionally empty judgments". Analyzing the clinical picture of hypomanic states, stress was placed on the notion of the coexistence of logical thinking (and in some cases these thinking patterns are concerned with a feeling of heightened cognitive ability) with thinking styles based on logical errors. In all patients hypermnesia appears more important than other factors. The above mentioned phenomena are the subject of further research. PMID:1301600

  13. Schizencephaly and Psychosis: A Rare Association

    Matias Carvalho Aguiar Melo

    2013-01-01

    Full Text Available Schizencephaly is a rare malformation of the central nervous system defined as a gray matter-lined cleft filled with cerebrospinal fluid that extends from the pial surface to the ventricle. Few cases of association with psychosis were reported in the scientific literature. We present a case of a 46-year-old woman, admitted into a psychiatric hospital with crises of psychomotor agitation, disorganized and erotized behavior, persecutory and self-reference delusions, and auditory and visual hallucinations. She also reported seizures since her childhood. A head CT scan revealed a large subarachnoid space communication with the adjacent lateral ventricle in the topography of occipital, temporal, and parietal lobes to the right, suggestive of schizencephaly.

  16. Williams syndrome and psychosis: a case report

    2014-01-01

    Introduction Mental comorbidities, such as phobia, obsessive compulsive symptoms and anxiety disorders, are common in Williams syndrome. However, psychotic symptoms are rare in these patients. We report a case of psychosis in a patient with Williams syndrome. Case presentation A 23-year-old Caucasian woman with Williams syndrome arrived at the emergency room with persecutory delusions, auditory and verbal hallucinations, soliloquies and psychomotor agitation. These symptoms were consistently present for 2 months. No evidence of other medical illnesses or psychoactive substances was found. There was no evidence of prior psychiatric symptoms or family history of psychiatric or neurological disorders. She was treated with antipsychotics and her symptoms were resolved. Conclusion We describe a rare case of a patient with Williams syndrome who experienced a nonorganic psychotic episode. Literature on this topic is scarce and, therefore, this case report intends to add further data about this comorbidity. PMID:24520861

  18. First aid guidelines for psychosis in Asian countries: A Delphi consensus study

    Langlands Robyn L

    2008-02-01

    Full Text Available Abstract Background Guidelines for how a member of the public should give first aid to a person who is becoming psychotic have been developed for English-speaking countries. However, these guidelines may not be appropriate for use in other cultures. A study was therefore carried out to examine whether it was possible to achieve consensus on guidelines that could apply in a range of Asian countries. Methods A Delphi consensus study was carried out with a panel of 28 Asian mental health clinicians drawn from Cambodia, China, Hong Kong, Indonesia, Japan, Malaysia, Mongolia, South Korea, Sri Lanka, Taiwan, Thailand and Vietnam. The panel was given a 211 item questionnaire about possible first aid actions and asked to rate whether they thought these should be included in guidelines. Panel members were invited to propose additional items. Results After three Delphi rounds, there were 128 items that were rated as "essential" or "important" by 80% or more of the panel members. These items covered: recognition of psychosis, encouraging and assisting the person to seek help, how to interact with the person, responding to acute psychosis, responding to aggression, and what to do if the person refuses to get professional help. Conclusion Despite the diversity of the countries involved, there was consensus on a core set of first aid items that were considered as suitable for assisting a psychotic person. Future work is needed to develop guidelines for specific countries.

Methods A Delphi consensus study was carried out with a panel of 28 Asian mental health clinicians drawn from Cambodia, China, Hong Kong, Indonesia, Japan, Malaysia, Mongolia, South Korea, Sri Lanka, Taiwan, Thailand and Vietnam. The panel was given a 211 item questionnaire about possible first aid actions and asked to rate whether they thought these should be included in guidelines. Panel members were invited to propose additional items. Results After three Delphi rounds, there were 128 items that were rated as "essential" or "important" by 80% or more of the panel members. These items covered: recognition of psychosis, encouraging and assisting the person to seek help, how to interact with the person, responding to acute psychosis, responding to aggression, and what to do if the person refuses to get professional help. Conclusion Despite the diversity of the countries involved, there was consensus on a core set of first aid items that were considered as suitable for assisting a psychotic person. Future work is needed to develop guidelines for specific countries. PMID:18291042

  20. Sudden psychotic episode probably due to meningoencephalitis and Chlamydia pneumoniae acute infection

    2005-01-01

    Abstract Background Since 9% to 20% of all cases of acute psychosis presenting to an Emergency Department (ED) are due to a general medical condition, cautious medical workup should be mandatory in such patients. Differential diagnosis must consider conditions as diverse as renal failure or CNS infection. Acute Chlamydia pneumoniae infection usually causes a self-limited respiratory syndrome. Rarely, acute neurological complications occur, with acute meningoencephalitis most frequently report...

    Experimental studies have demonstrated that not only dopaminergic signaling but also glutamatergic/NMDA receptor signaling play indispensable roles in the development of methamphetamine psychosis. Our recent genetic studies provided evidence that genetic variants of glutamate-related genes such as DTNBP1, GLYT1, and G72, which are involved in glutamate release and regulation of co-agonists for NMDA receptors, conferred susceptibility to methamphetamine psychosis. Serine racemase converts l-serine to d-serine, which is an endogenous co-agonist for NMDA receptors. Three single nucleotide polymorphisms (SNPs) in the promoter region of the serine racemase gene (SRR), rs224770, rs3760229, and rs408067, were proven to affect the transcription activity of SRR. Therefore, we examined these SNPs in 225 patients with methamphetamine psychosis and 291 age- and sex-matched controls. There was no significant association between methamphetamine psychosis and any SNP examined or between the disorder and haplotypes comprising the three SNPs. However, rs408067 was significantly associated with the prognosis for methamphetamine psychosis and multi-substance abuse status. The patients with C-positive genotypes (CC or CG) of rs408067 showed better prognosis of psychosis after therapy and less abuse of multiple substances than the patients with GG genotypes. Because the C allele of rs408067 reduces the expression of SRR, a lower d-serine level or reduced NMDA receptor activation may affect the prognosis of methamphetamine psychosis and multiple substance abuse. Our sample size is, however, not large enough to eliminate the possibility of a type I error, our findings must be confirmed by replicate studies with larger samples. PMID:21886585

  3. [First-episodes psychosis: clinical and epidemiological news].

    Tournier, M

    2013-09-01

    In the context of the development of early intervention for first-episode psychosis, this manuscript reviews new data with respect to its incidence, risk factors and evolution. Annual incidence of non-affective psychosis appeared to be between 14 and 30/100,000 in people aged 18-64. Incidence decreases with age and is twice higher in men than in women. There is an interaction between age and gender; the risk of psychosis decreases with age faster in men than in women. Thus, for schizophrenia, incidence rate is twice higher in men under 45 year-old and similar in both genders after. There is evidence that genetic and environmental factors may cause enduring liability to psychotic disorder, and, in addition, that genes and environment may interact synergistically. Some environmental factors have been identified; they concern foetal life, childhood or adolescence and may be conceptualized at the individual or the contextual level. The definition of recent onset psychosis may be based on duration of psychosis, between two and five years. Its development is identified through the occurrence of major psychotic symptoms, such as positive, negative symptomatology or disorganization, and impairment of social functioning. The types and patterns of occurrence and of evolution of psychotic symptoms have a prognostic impact. A long duration of untreated psychosis impacts symptomatology. It is associated with less severe positive symptoms at baseline and more severe after three years, insidious onset, male gender, early onset, and diagnosis of schizophrenia. Recent onset psychosis is often associated with comorbidities, such as depression, anxiety disorders, suicidal behaviours, and addiction. Symptomatic remission rates are found between 25 and 60%. Symptomatic and functional remissions favour each other. A third to half of patients is active, employed or students. Symptoms and evolution are various in studies, probably corresponding to various patho-physiological mechanisms

  4. Facial emotion recognition in first-episode schizophrenia and bipolar disorder with psychosis.

    Daros, Alexander R; Ruocco, Anthony C; Reilly, James L; Harris, Margret S H; Sweeney, John A

    2014-03-01

    Patients with schizophrenia and bipolar disorder have difficulties recognizing facial expressions of emotion. Differences in deficits between these disorders and the effects of treating acute symptoms of illness with antipsychotic medication on these deficits are not well characterized. First-episode patients with schizophrenia (n=24) and psychotic bipolar I disorder (n=16) were compared to a healthy control group (n=32) on the Penn Emotional Acuity Test. Patients were studied during an acute psychotic episode and after seven weeks of treatment with antipsychotic medication. During acute psychosis, bipolar patients showed deficits recognizing subtle facial expressions of happiness and sadness, and this deficit did not resolve with treatment. Schizophrenia patients similarly had difficulty recognizing subtle happy faces during acute illness that also did not resolve with treatment. In addition, problems recognizing subtle expressions of sadness among schizophrenia patients were apparent after treatment. Poorer emotion recognition at follow-up was related to negative symptom severity for schizophrenia patients. These findings highlight the severity and persistence of emotion recognition deficits early in the course of psychotic bipolar disorder and schizophrenia, and demonstrate an association of emotion processing deficits to negative symptoms in schizophrenia during periods of relative clinical stability.

    the dependent variable was a postindex year diagnosis of psychosis. The OR associated with sexual victimization (OR = 10.04; 95% CI 2.50-40.33) indicted an increased likelihood of psychosis while controlling for the other predictors in the model. Conclusions: This study found that sexual victimization...... significantly increased the likelihood of a diagnosis of psychosis and therefore suggests that there may be a role for traumatic experiences in the etiology of psychosis....

  6. Childhood trauma and cognitive function in first-episode affective and non-affective psychosis.

    Aas, Monica

    2011-06-01

    A history of childhood trauma is reportedly more prevalent in people suffering from psychosis than in the general population. Childhood trauma has also been linked to cognitive abnormalities in adulthood, and cognitive abnormalities, in turn, are one of the key clinical features of psychosis. Therefore, this study investigated whether there was a relationship between childhood trauma and cognitive function in patients with first-episode psychosis. The potential impact of diagnosis (schizophrenia or affective psychosis) and gender on this association was also examined.

    Many neuropsychiatric illnesses are associated with psychosis, i.e., hallucinations (perceptions in the absence of causative stimuli) and delusions (irrational, often bizarre beliefs). Current models of brain function view perception as a combination of two distinct sources of information: bottom-up sensory input and top-down influences from prior knowledge. This framework may explain hallucinations and delusions. Here, we characterized the balance between visual bottom-up and top-down processing in people with early psychosis (study 1) and in psychosis-prone, healthy individuals (study 2) to elucidate the mechanisms that might contribute to the emergence of psychotic experiences. Through a specialized mental-health service, we identified unmedicated individuals who experience early psychotic symptoms but fall below the threshold for a categorical diagnosis. We observed that, in early psychosis, there was a shift in information processing favoring prior knowledge over incoming sensory evidence. In the complementary study, we capitalized on subtle variations in perception and belief in the general population that exhibit graded similarity with psychotic experiences (schizotypy). We observed that the degree of psychosis proneness in healthy individuals, and, specifically, the presence of subtle perceptual alterations, is also associated with stronger reliance on prior knowledge. Although, in the current experimental studies, this shift conferred a performance benefit, under most natural viewing situations, it may provoke anomalous perceptual experiences. Overall, we show that early psychosis and psychosis proneness both entail a basic shift in visual information processing, favoring prior knowledge over incoming sensory evidence. The studies provide complementary insights to a mechanism by which psychotic symptoms may emerge. PMID:26460044

    It is essential to recognize and treat psychosis in Parkinson disease (PD) for several reasons. Multiple studies have shown that psychosis in PD patients is a strong risk factor for nursing home placement. Psychosis may be the single greatest stress for caretakers of PD patients, it is often persistent, and its presence markedly increases the risk of mortality.

  15. Psychosis in Later Life: A Review and Update.

    Colijn, Mark A; Nitta, Bradley H; Grossberg, George T

    2015-01-01

    Psychosis is relatively common in later life and can present in a wide variety of contexts, including early-onset and late-onset schizophrenia, delusional disorder, mood disorders, and various dementias. It can also occur as the result of numerous medical and neurological diseases and from the use of certain medications. Although identifying the cause of psychosis in older patients can be challenging, the unique clinical features associated with the different disorders can help in making the diagnosis. Accurate diagnosis of psychosis in older populations is essential, as its treatment varies depending on the context in which it appears. Despite the safety concerns regarding the use of antipsychotics in older patients, certain pharmacological treatments appear to be both efficacious and reasonably safe in treating psychosis in older populations. Additionally, although research is limited, numerous psychosocial therapies appear promising. This review summarizes the literature on the epidemiology, clinical characteristics, neuroimaging, and treatment of psychosis in later life, and serves as an update to past reviews on this topic.

    2015-12-01

    A childhood history of attention deficit hyperactivity disorder (ADHD) is common in psychotic disorders, yet prescription stimulants may interact adversely with the physiology of these disorders. Specifically, exposure to stimulants leads to long-term increases in dopamine release. We therefore hypothesized that individuals with psychotic disorders previously exposed to prescription stimulants will have an earlier onset of psychosis. Age of onset of psychosis (AOP) was compared in individuals with and without prior exposure to prescription stimulants while controlling for potential confounding factors. In a sample of 205 patients recruited from an inpatient psychiatric unit, 40% (n = 82) reported use of stimulants prior to the onset of psychosis. Most participants were prescribed stimulants during childhood or adolescence for a diagnosis of ADHD. AOP was significantly earlier in those exposed to stimulants (20.5 vs. 24.6 years stimulants vs. no stimulants, p history of a cannabis use disorder or other drugs of abuse, and family history of a first-degree relative with psychosis, the association between stimulant exposure and earlier AOP remained significant. There was a significant gender × stimulant interaction with a greater reduction in AOP for females, whereas the smaller effect of stimulant use on AOP in males did not reach statistical significance. In conclusion, individuals with psychotic disorders exposed to prescription stimulants had an earlier onset of psychosis, and this relationship did not appear to be mediated by IQ or cannabis.

  17. Psychosis in Parkinson's Disease: Epidemiology, Pathophysiology, and Management.

    Chang, Anna; Fox, Susan H

    2016-07-01

    Psychotic symptoms are common in Parkinson's disease (PD) and are associated with poorer quality of life and increased caregiver burden. PD psychosis is correlated with several factors, such as more advanced disease, cognitive impairment, depression, and sleep disorders. The underlying causes of psychosis in PD thus involve a complex interplay between exogenous (e.g., drugs, intercurrent illnesses) and endogenous (e.g., PD disease pathology) factors. Current theories of the pathophysiology of PD psychosis have come from several neuropathological and neuroimaging studies that implicate pathways involving visual processing and executive function, including temporo-limbic structures and neocortical gray matter with altered neurotransmitter functioning (e.g., dopamine, serotonin, and acetylcholine). Treatment of PD psychosis requires a step-wise process, including initial careful investigation of treatable triggering conditions and a comprehensive evaluation with adjustment of PD medications and/or initiation of specific antipsychotic therapies. Clozapine remains the only recommended drug for the treatment of PD psychosis; however, because of regular blood monitoring, quetiapine is usually first-line therapy, although less efficacious. Emerging studies have focused on agents involving other neurotransmitters, including the serotonin 5-HT2A receptor inverse agonist pimavanserin, cholinesterase inhibitors, and antidepressants and anxiolytics.

  18. [Acute and transient psychotic disorders].

    Marneros, A; Pillmann, F; Haring, A; Balzuweit, S

    2000-04-01

    Psychotic disorders with acute onset, a dramatic and polymorphous symptomatology and rapid resolution have been described in different countries and by different psychiatric schools. They have been called cycloid psychosis, bouffée délirante, psychogenic psychosis or good prognosis schizophrenia. ICD-10 has given an operational definition under the name "acute and transient psychotic disorders" (F23). Their nosological status is unclear. The Halle-Study of acute and transient psychotic disorders (ATPD) has investigated in a prospective manner clinical, para-clinical features and course of illness in 42 patients with ATPD and matched controls with positive schizophrenia, bipolar schizoaffective disorders as well as mentally healthy patients with acute surgical conditions. First results of our study show that ATPD amount to 4% of psychotic in-patients, prefer female sex, show short prodromi, marked affective disturbances within the episode and much better outcome as schizophrenic psychoses according to psychopathological, social, psychological and biographical criteria. Though ATPD may still be an inhomogeneous group, their clinical delineation from schizophrenia seems justified. PMID:10907609

  1. Epidemiology of psychosis in Parkinson's disease.

    Fénelon, Gilles; Alves, Guido

    2010-02-15

    Psychotic symptoms are frequent and disabling in patients with Parkinson's disease (PD). Methodological issues in the epidemiology of PD associated psychosis (PDP) include differences in the symptoms assessed, the methods of assessment, and the selection of patients. Most studies are prospective clinic-based cross-sectional studies providing point prevalence rates in samples on dopaminergic treatment. Visual hallucinations are present in about one quarter to one third of the patients, auditory in up to 20%. Tactile/somatic, and olfactory hallucinations are usually not systematically sought. Minor phenomena such as sense of presence and visual illusions affect 17 to 72% of the patients, and delusions about 5%. Lifetime prevalence of visual hallucinations reaches approximately 50%. Prospective longitudinal cohort studies suggest that hallucinations persist and worsen in individual patients, and that their prevalence increases with time. A facilitating role of treatment on PDP is demonstrated at least for dopaminergic agonists, but there is no simple dose-effect relationship between dopaminergic treatment and the presence or severity of hallucinations. The main endogenous non-modifiable risk factor is cognitive impairment. Other associated factors include older age/longer duration of PD, disease severity, altered dream phenomena, daytime somnolence, and possibly depression and dysautonomia. PDP reduces quality of life in patients and increases caregiver distress, and is an independent risk factor for nursing home placement and development of dementia. PMID:19740486

    The largest task for psychiatry in Japan today is the deinstitutionalization of patients with psychiatric disorders. In Japan, all citizens are covered by a national health plan, and about 70% of the total cost is covered by the national health insurance scheme. At present, however, there is still no category for early intervention in the national health reimbursement schedule. Recent research has shown that the mean duration of untreated psychosis (DUP) at seven university hospitals in Japan was 17.6 months. We present data using case vignettes suggesting that pharmacotherapy might be overused in prodromal cases. The concept of an At-Risk Mental State (ARMS)/prodromal state might not yet be widely recognized among Japanese psychiatrists. We outline early intervention initiatives in Japan; The Japanese Society for Prevention and Early Intervention in Psychiatry (JSEIP), and a representative early intervention facility for young people is the "Il Bosco" in Tokyo. There are several leading centers for early intervention research and practice in Japan. Most of them are driven by university departments of psychiatry with respect to both research and clinical activities. The development of services for early intervention is expected to reduce stigmatization, prevent suicide among young persons, and promote general knowledge about mental health. There are several common or similar issues among Asian countries, including service systems, community attitudes to psychiatric illness including stigma, and dependence on pharmacotherapy.

  3. Social anxiety and the shame of psychosis: a study in first episode psychosis.

    Birchwood, Max; Trower, Peter; Brunet, Kat; Gilbert, Paul; Iqbal, Zaffer; Jackson, Chris

    2007-05-01

    Social anxiety disorder (SaD) or social phobia is a co-morbid affective disorder in schizophrenia, present in up to one in three individuals. We employ 'social rank' theory to predict that one pathway to social anxiety in schizophrenia is triggered by the anticipation of a catastrophic loss of social status that the stigma of schizophrenia can entail. A group of 79 people with a first episode of psychosis were assessed for social anxiety: hypotheses were tested comparing 23 socially anxious and 56 non-anxious patients on measures of cognitive appraisals of shame/stigma of psychosis and perceived social status, controlling for depression, psychotic symptoms and general psychopathology. Participants with social anxiety experienced greater shame attached to their diagnosis and felt that the diagnosis placed them apart from others, i.e., socially marginalised them and incurred low social status. We propose a stigma model of social anxiety that makes testable predictions about how the shame beliefs may contaminate social interaction and thereby exacerbate and maintain social phobia.

    Objective: To evaluate the therapeutic effect of acupuncture in the treatment of depressive psychosis.Methods: A total of 62 cases of depressive psychosis patients were randomly divided into treatment group (n=32) and control group (n=30). Acupoints used in treatment group were bilateral Hegu (LI 4), bilateral Taichong (LR 3), Baihui (GV 20) and Yintang (EX-HN 3). Patients of control group were asked to take Fluoxertine hydrochloride 20 mg/d.The therapeutic effect was assessed using Hamilton's depression (HAMD) scales. Results: After 8 weeks' treatment,in treatment and control groups, 4 and 3 cases were cured, 8 and 6 experienced marked improvement, 14 and 14 had improvement, 6 and 7 had no effect, with the effective rates being 81.25% and 76. 66% separately, and no significant difference was found between two groups in HAMD scales (P>0.05). Conclusion: Acupuncture therapy is an effective method for treatment of depressive psychosis.

  5. Neural correlates of insight in dreaming and psychosis.

    The idea that dreaming can serve as a model for psychosis has a long and honourable tradition, however it is notoriously speculative. Here we demonstrate that recent research on the phenomenon of lucid dreaming sheds new light on the debate. Lucid dreaming is a rare state of sleep in which the dreamer gains insight into his state of mind during dreaming. Recent electroencephalogram (EEG) and functional magnetic resonance imaging (fMRI) data for the first time allow very specific hypotheses about the dream-psychosis relationship: if dreaming is a reasonable model for psychosis, then insight into the dreaming state and insight into the psychotic state should share similar neural correlates. This indeed seems to be the case: cortical areas activated during lucid dreaming show striking overlap with brain regions that are impaired in psychotic patients who lack insight into their pathological state. This parallel allows for new therapeutic approaches and ways to test antipsychotic medication. PMID:25092021

  6. Fetishistic transvestism in a patient with mental retardation and psychosis

    Rajmohan Velayudhan

    2014-01-01

    Full Text Available Fetishistic transvestism is a disorder of sexual preference associated with fantasies and sexual urges to dress in opposite gender clothing as a means of arousal and as an adjunct to masturbation and coitus. The disorder has been reported in people with learning disabilities. The disorder has been reported in a young male with dull normal intelligence. Transvestism though has been described in schizophrenia and psychosis and fetishism has been described in the course of simple schizophrenia, there are no reports of fetishistic transvestism in a patient with mental retardation and psychosis. A case of fetishistic transvestism in a patient with mental retardation and psychosis with treatment and relevant review of literature is reported.

    Transsexualism is a rare disorder with an uncertain aetiology. Recently, biological factors have been considered to be important in its occurrence. The relationship of transsexualism with psychosis is not known; in most cases no specific relationship exists, though few cases of symptomatic transsexualism have been reported. In the following case, cross dressing and homosexual orientation was present from an early age, but gender dysphoria became manifest only after the onset of an acute psych...

  9. Increased density of DISC1-immunoreactive oligodendroglial cells in fronto-parietal white matter of patients with paranoid schizophrenia.

    Bernstein, Hans-Gert; Jauch, Esther; Dobrowolny, Henrik; Mawrin, Christian; Steiner, Johann; Bogerts, Bernhard

    2016-09-01

    Profound white matter abnormalities have repeatedly been described in schizophrenia, which involve the altered expression of numerous oligodendrocyte-associated genes. Transcripts of the disrupted-in-schizophrenia 1 (DISC1) gene, a key susceptibility factor in schizophrenia, have recently been shown to be expressed by oligodendroglial cells and to negatively regulate oligodendrocyte differentiation and maturation. To learn more about the putative role(s) of oligodendroglia-associated DISC1 in schizophrenia, we analyzed the density of DISC1-immunoreactive oligodendrocytes in the fronto-parietal white matter in postmortem brains of patients with schizophrenia. Compared with controls (N = 12) and cases with undifferentiated/residual schizophrenia (N = 6), there was a significantly increased density of DISC1-expressing glial cells in paranoid schizophrenia (N = 12), which unlikely resulted from neuroleptic treatment. Pathophysiologically, over-expression of DISC1 protein(s) in white matter oligodendrocytes might add to the reduced levels of two myelin markers, 2',3'-cyclic-nucleotide 3'-phosphodiesterase and myelin basic protein in schizophrenia. Moreover, it might significantly contribute to cell cycle abnormalities as well as to deficits in oligodendroglial cell differentiation and maturation found in schizophrenia. PMID:26315603

  10. The cannabis pathway to non-affective psychosis may reflect less neurobiological vulnerability

    Else-Marie eLøberg

    2014-11-01

    Full Text Available There is a high prevalence of cannabis use reported in non-affective psychosis.

    There is a high prevalence of cannabis use reported in non-affective psychosis. Early prospective longitudinal studies conclude that cannabis use is a risk factor for psychosis, and neurochemical studies on cannabis have suggested potential mechanisms for this effect.

    The present study explored the conversion rate in individuals with Attenuated Psychosis Syndrome (APS) and potential predictor for transition in mainland China. Sixty-three participants identified as APS were followed up 6 months later. The results showed that 17% of individuals with APS converted to full-blown psychosis. The converters exhibited significantly poorer emotional experience and expression than the non-converters at baseline. A further binary logistic regression analysis showed that emotional experience could predict the transition (Wald = 4.18, p = 0.041, 95% CI = 1.04~6.82). The present study suggests an important role of emotional processing in the prediction of the development of full-blown psychosis. PMID:27313553

  14. Persistent deficits in hippocampal synaptic plasticity accompany losses of hippocampus-dependent memory in a rodent model of psychosis

    Valentina eWiescholleck

    2013-03-01

    Full Text Available Irreversible N-methyl-D-aspartate receptor (NMDAR antagonism is known to provoke symptoms of psychosis and schizophrenia in healthy humans. NMDAR hypofunction is believed to play a central role in the pathophysiology of both disorders and in an animal model of psychosis, that is based on irreversible antagonism of NMDARs, pronounced deficits in hippocampal synaptic plasticity have been reported shortly after antagonist treatment. Here, we examined the long-term consequences for long-term potentiation (LTP of a single acute treatment with an irreversible antagonist and investigated whether deficits are associated with memory impairments.The ability to express long-term potentiation (LTP at the perforant pathway – dentate gyrus synapse, as well as object recognition memory was assessed 1, 2, 3 and 4 weeks after a single -treatment of the antagonist, MK801. Here, LTP in freely behaving rats was significantly impaired at all time-points compared to control LTP before treatment. Object recognition memory was also significantly poorer in MK801-treated compared to vehicle-treated animals for several weeks after treatment. Histological analysis revealed no changes in brain tissue.Taken together, these data support that acute treatment with an irreversible NMDAR antagonist persistently impairs hippocampal functioning on behavioral, as well as synaptic levels. The long-term deficits in synaptic plasticity may underlie the cognitive impairments that are associated with schizophrenia-spectrum disorders.

  15. Attention in schizophrenia and in epileptic psychosis

    I.C.J Kairalla

    2008-01-01

    Full Text Available The adaptive behavior of human beings is usually supported by rapid monitoring of outstanding events in the environment. Some investigators have suggested that a primary attention deficit might trigger symptoms of schizophrenia. In addition, researchers have long discussed the relationship between schizophrenia and the schizophrenia-like psychosis of epilepsy (SLPE. On the basis of these considerations, the objective of the present study was to investigate attention performance of patients with both disorders. Patient age was 18 to 60 years, and all patients had received formal schooling for at least four years. Patients were excluded if they had any systemic disease with neurologic or psychiatric comorbidity, or a history of brain surgery. The computer-assisted TAVIS-2R test was applied to all patients and to a control group to evaluate and discriminate between selective, alternating and sustained attention. The TAVIS-2R test is divided into three parts: one for selective attention (5 min, the second for alternating attention (5 min, and the third for the evaluation of vigilance or sustained attention (10 min. The same computer software was used for statistical analysis of reaction time, omission errors, and commission errors. The sample consisted of 36 patients with schizophrenia, 28 with interictal SLPE, and 47 healthy controls. The results of the selective attention tests for both patient groups were significantly lower than that for controls. The patients with schizophrenia and SLPE performed differently in the alternating and sustained attention tests: patients with SLPE had alternating attention deficits, whereas patients with schizophrenia showed deficits in sustained attention. These quantitative results confirmed the qualitative clinical observations for both patient groups, that is, that patients with schizophrenia had difficulties in focusing attention, whereas those with epilepsy showed perseveration in attention focus.

    2016-01-01

    In this review article, we outline the evidence linking attachment adversity to psychosis, from the premorbid stages of the disorder to its clinical forms. To better understand the neurobiological mechanisms through which insecure attachment may contribute to psychosis, we identify at least five neurobiological pathways linking attachment to risk for developing psychosis. Besides its well documented influence on the hypothalamic-pituary-adrenal (HPA) axis, insecure attachment may also contribute to neurodevelopmental risk through the dopaminergic and oxytonergic systems, as well as bear influence on neuroinflammation and oxidative stress responses. We further consider the neuroscientific and behavioral studies that underpin mentalization as a suite of processes potentially moderating the risk to transition to psychotic disorders. In particular, mentalization may help the individual compensate for endophenotypical impairments in the integration of sensory and metacognitive information. We propose a model where embodied mentalization would lie at the core of a protective, resilience response mitigating the adverse and potentially pathological influence of the neurodevelopmental cascade of risk for psychosis.

  2. Neurophysiology for Detection of High Risk for Psychosis.

    Pantlin, Lara N; Davalos, Deana

    2016-01-01

    Schizophrenia is a complex and often disabling disorder that is characterized by a wide range of social, emotional, and cognitive deficits. Increasing research suggests that the greatest social and cognitive therapeutic impact comes from early identification. The present study applied a well-established neurophysiological paradigm in the schizophrenia literature, mismatch negativity (MMN), to college students identified as high risk (HR) for psychosis to investigate MMN as a potential biomarker for the onset of psychosis. The hypothesis was that HR would exhibit attenuated MMN amplitudes compared to controls, as has been established in individuals with chronic schizophrenia. Participants (N = 121) were separated into Group 1 (controls) (n 1 = 72) and Group 2 (HR) (n 2 = 49) based on the established cutoff score of the 16-item Prodromal Questionnaire. Participants then completed a time based MMN paradigm during which brain activity was recorded with EEG. For all electrode locations, controls demonstrated significantly more negative amplitudes than HR (Cz: F(1,119) = 8.09, p = .005; Fz: F(1, 119) = 5.74, p = .018; Pz: F(1,119) = 5.88, p = .017). Results suggested that MMN may assist in identifying those who appear high-functioning but may be at risk for later development of psychosis or cognitive and psychological difficulties associated with psychosis.

  5. Incentive motivation in first-episode psychosis: A behavioural study

    Blackwell Andrew D

    2008-05-01

    Full Text Available Abstract Background: It has been proposed that there are abnormalities in incentive motivational processing in psychosis, possibly secondary to subcortical dopamine abnormalities, but few empirical studies have addressed this issue. Methods: We studied incentive motivation in 18 first-episode psychosis patients from the Cambridge early psychosis service CAMEO and 19 control participants using the Cued Reinforcement Reaction Time Task, which measures motivationally driven behaviour. We also gathered information on participants' attentional, executive and spatial working memory function in order to determine whether any incentive motivation deficits were secondary to generalised cognitive impairment. Results: We demonstrated the anticipated "reinforcement-related speeding" effect in controls (17 out of 19 control participants responded faster during an "odd-one-out" task in response to a cue that indicated a high likelihood of a large points reward. Only 4 out of 18 patients showed this effect and there was a significant interaction effect between reinforcement probability and diagnosis on reaction time (F1,35 = 14.2, p = 0.001. This deficit was present in spite of preserved executive and attentional function in patients, and persisted even in antipsychotic medication free patients. Conclusion: There are incentive motivation processing abnormalities in first-episode psychosis; these may be secondary to dopamine dysfunction and are not attributable to generalised cognitive impairment.

  9. Psychosis and Substance Use: Implications for Conditional Release Readiness Evaluations.

    Tabernik, Holly E; Vitacco, Michael J

    2016-03-01

    In Foucha v. Louisiana (1992), the United States Supreme Court ruled that individuals adjudicated not guilty by reason of insanity (NGRI) could not remain in a forensic hospital if they were no longer mentally ill and dangerous. Since this decision, a variety of important questions have arisen related to the insanity defense and what should happen to insanity acquittees post-adjudication. This article provides an analysis of clinical issues confronting forensic examiners when psychosis as a result of substance abuse is the underlying condition supporting an insanity defense. To accomplish this analysis, this article provides the reader with a review of literature showing the complex relationship between psychosis and substance abuse. Second, this article investigates how substance-induced psychosis may impact both insanity opinions and subsequent conditional release decisions. Third, the article aims to provide research-driven information to assist clinicians in conducting conditional release evaluations. Finally, this paper provides a model for evaluating dangerousness in the context of conditional release evaluations. Given the substantial comorbidity between substance abuse and psychosis, it is critical for researchers and clinicians to consider potential effects of substance abuse when evaluating insanity acquittees for conditional release, especially as substance use relates to future dangerousness.

We present the case of a 35-year-old ranger who had no history of acute or chronic infectious disease or any previous neuropsychiatric symptoms. He arrived at the Psychiatry Clinic and was admitted as an emergency case, displaying bizarre behavior, hallucinations, paranoid ideation, and delusional faults. These symptoms had first appeared 7 days earlier. An objective examination revealed abnormalities of behavior, anxiety, visual hallucinations, choreiform, and tic-like facial movements. After the administration of neuroleptic and antidepressant treatment, he showed an initial improvement, but on day 10 entered into a severe catatonic state with signs of meningeal irritation and was transferred to the intensive care unit. An electroencephalogram showed diffuse irritative changes, raising the possibility of encephalitis.

  11. Treatment of Psychosis and Dementia in Parkinson’s Disease

    Goldman, Jennifer G.; Holden, Samantha

    2014-01-01

    Opinion Statement Parkinson’s disease (PD) has been increasingly recognized as having a multitude of non-motor symptoms including psychosis, cognitive impairment and dementia, mood disturbances, fatigue, apathy, and sleep disorders. Psychosis and dementia, in particular, greatly affect quality of life for both patients and caregivers and are associated with poor outcomes. Safe and effective treatment options for psychosis and dementia in PD are much needed. Antipsychotics with dopamine-blocking properties can worsen parkinsonian motor features and have been associated with increased morbidity and mortality in elderly, dementia patients. For treating PD psychosis, a first step would be eliminating confounding variables, such as delirium, infections or toxic-metabolic imbalances, followed by simplifying parkinsonian medications as tolerated. If additional treatment is warranted after such interventions, clozapine or quetiapine can be implemented at the low dose levels typically needed by PD patients. Although quetiapine is easy-to-use in clinical settings, does not require blood count monitoring like clozapine, and is anecdotally beneficial, it remains “investigational” in evidence-based medicine reviews. Though not currently available, the novel 5-HT2a inverse agonist, pimavanserin has shown promise in the treatment of PD psychosis. Current treatments for PD dementia are mostly derived from those utilized in Alzheimer’s disease, focusing mainly on cholinesterase inhibitors and memantine, a NMDA receptor antagonist. Rivastigmine, the only approved medication for PD dementia, is a reasonable first choice. Other cholinesterase inhibitors and memantine have not yet achieved recommendation status in evidence-based medicine reviews but are well tolerated in studies of PD dementia patients. At present, there are no approved treatments for mild cognitive impairment in PD, but rasagiline, a selective MAO-B inhibitor, and atomoxetine, a serotonin norepinephrine

  12. Basic disturbances of information processing in psychosis prediction

    Mitja eBodatsch

    2013-08-01

    Full Text Available The basic symptoms (BS approach provides a valid instrument in predicting psychosis onset and represents moreover a significant heuristic framework for research. The term ‘basic symptoms’ denotes subtle changes of cognition and perception in the earliest and prodromal stages of psychosis development. BS are thought to correspond to disturbances of neural information processing. Following the heuristic implications of the BS approach, the present paper aims at exploring disturbances of information processing, revealed by fMRI and EEG as characteristics of the at-risk state of psychosis. Furthermore, since high-risk studies employing UHR criteria revealed non-conversion rates commonly exceeding 50%, thus warranting approaches that increase specificity, the potential contribution of neural information processing disturbances to psychosis prediction is reviewed. In summary, the at-risk state seems to be associated with information processing disturbances. Moreover, fMRI investigations suggested that disturbances of language processing domains might be a characteristic of the prodromal state. Neurophysiological studies revealed that disturbances of sensory processing may assist psychosis prediction in allowing for a quantification of risk in terms of magnitude and time. The latter finding represents a significant advancement since an estimation of the time to event has not yet been achieved by clinical approaches. Some evidence suggests a close relationship between self-experienced BS and neural information processing. With regard to future research, the relationship between neural information processing disturbances and different clinical risk concepts warrants further investigations. Thereby,a possible time sequence in the prodromal phase might be of particular interest.

Methods: A sample of 36 patients with early-onset schizophrenia spectrum psychosis was compared to a control sample of 36 patients with migraine. We assessed early childhood neurodevelopmental milestones using a modified version of the General Developmental Scale, general intellectual ability using the Wechsler Intelligence Scale for Children–Revised or Leiter International Performance Scale–Revised for patients with speech and language abnormalities, and neurological soft signs with specific regard to subtle motor impairment. Results: Subjects with early-onset psychosis had a higher rate of impaired social development (P=0.001, learning difficulties (P=0.04, enuresis (P=0.0008, a lower intelligence quotient (P<0.001, and subtle motor impairments (P=0.005 than control subjects. Conclusion: We suggest that neurodevelopment in early-onset psychosis is characterized by a global impairment of functional and adaptive skills that manifests from early childhood, rather than a delay or limitation in language and motor development. The current evidence is based on a small sample and should be investigated in larger samples in future research.

Methods Before the treatment, MMPI was administrated to the patient with first-episode paranoid schizophrenia. Analyzed the efficiency of the survey results and compared the results with that of controls of the same number. Results ignificant differences were found between the patients with first-episode paranoid schizophrenia and healthy controls in two validity scales and T-scores of seven clinical sub-scale. For the T-scorcs of the MMPI two point codes types for Pa (paranoid) and Sc (schizophrenia), there was a significant difference between the study and control group. For first-episode paranoid schizophrenia, the MMPI results cannot resolve the contradictions between sensitivity and specificity, the false positive and negative results should be noticed. Conclusion MMPI results were more specific and sensitive compared with the normal controls. However, it cannot replace clinical psychiatric examination for diagnosis of the first-episode paranoid schizophrenia.

    Full Text Available Background and Objectives: Aggressiveness is a common component of manic symptoms. The aim of this study was to determine the clinical characteristics associated with aggressive behaviour in bipolar patients with acute manic episodes. Methods: A study was carried out with 173 patients who met the DSM-IV criteria for manic or mixed bipolar disorder. Clinical and demographic variables were evaluated using the Positive and Negative Symptoms Scale (PANSS, the Young Mania Rating Scale (YMRS, the Brief Psychiatric Rating Scale (BPRS, and the Hamilton Depression Rating Scale (HDRS. Significance and independence of relevant variables were tested with regression models. Results: Forty percent of patients displayed aggressive behaviour. Involuntary nature of admission, positive psychotic symptoms and lack of insight were predictors of aggressive behaviour in manic patients. Conclusions: Aggressive behaviour during acute manic episodes appears to be related with the severity of the psychopathology, and particularly positive psychotic symptoms, involuntary admissions and lack of insight.

  18. Therapeutic Potential of Cannabinoids in Psychosis.

    Leweke, F Markus; Mueller, Juliane K; Lange, Bettina; Rohleder, Cathrin

    2016-04-01

    Over recent years, the interest in the endocannabinoid system (ECS) as a new target for the treatment of schizophrenia has evolved. The ECS represents one of the most relevant neurotransmitter systems in the brain and mainly fulfills a homeostatic role in terms of neurotransmission but also with respect to inflammatory processes. Two main approaches to the modulation of endocannabinoid functioning have been chosen so far. First, the selective blockade or inverse agonism of the type 1 cannabinoid receptor has been tested for the improvement of acute psychotic symptoms, as well as for the improvement of cognitive functions in schizophrenia. This was not effective in either case. Second, the modulation of endocannabinoid levels by use of the phytocannabinoid cannabidiol and selective fatty acid amide hydrolase inhibitors has been proposed, and the antipsychotic properties of cannabidiol are currently being investigated in humans. Unfortunately, for most of these trials that have focused on psychopathological and cognitive effects of cannabidiol, no published data are available. However, there is first evidence that cannabidiol may ameliorate psychotic symptoms with a superior side-effect profile compared with established antipsychotics. In conclusion, several clinical trials targeting the ECS in acute schizophrenia have either been completed or are underway. Although publicly available results are currently limited, preliminary data indicate that selected compounds modulating the ECS may be effective in acute schizophrenia. Nevertheless, so far, sample sizes of patients investigated are not sufficient to come to a final judgment, and no maintenance studies are available to ensure long-term efficacy and safety.

  19. Transient psychosis due to painless thyroiditis in a patient with anxiety disorder: a case report

    Kobayashi Nobuyuki

    2011-10-01

    Full Text Available Abstract Introduction There are few reports on thyrotoxic psychosis caused by diseases other than Graves' disease or toxic nodular goiter. Case presentation A 64-year-old Japanese woman was treated for anxiety disorder in our clinic for 10 years. She had five episodes of transient psychosis during the first five years. When she developed psychosis without neck pain 10 years after her first visit, a laboratory reexamination revealed that she had subclinical hyperthyroidism, and tested positive for antithyroid autoantibodies, negative for thyroid stimulating hormone receptor antibody and had decreased radioactive iodine uptake. She was diagnosed as having painless thyroiditis. The hyperthyroidism disappeared within a month, and the psychosis lasted for three months. Conclusion To the best of our knowledge, this is the first report of psychosis due to painless thyroiditis-induced hyperthyroidism. Physical symptoms of painless thyroiditis are often so mild that careful differential diagnosis is necessary in the cases of transient psychosis.

    2005-01-01

    OBJECTIVES: To investigate whether age at onset of epilepsy, type of epilepsy, family history of psychosis, or family history of epilepsy affect the risk of schizophrenia or schizophrenia-like psychosis among patients with epilepsy. DESIGN: Comparison of population based data. SETTING: Danish...... people with a history of epilepsy. The effect of epilepsy was the same in men and in women and increased with age. Family history of psychosis and a family history of epilepsy were significant risk factors for schizophrenia and schizophrenia-like psychosis, and the effect of epilepsy, both in cases and...... families, was greater among people with no family history of psychosis. In addition, the increased risk for schizophrenia or schizophrenia-like psychosis did not differ by type of epilepsy but increased with increasing number of admissions to hospital and, particularly, was significantly greater for people...

  1. A feasibility study of acceptance and commitment therapy for emotional dysfunction following psychosis

    White, R G; Gumley, A.; McTaggart, J.; Rattrie, L.; McConville, D; Cleare, S.; Mitchell, G

    2011-01-01

    The experience of psychosis can lead to depression, anxiety and fear. Acceptance and Commitment Therapy (ACT) facilitates individuals to accept difficult mental experiences and behave in ways that are consistent with personally held values. This study was a single (rater) blind pilot randomised controlled trial of ACT for emotional dysfunction following psychosis. Twenty-seven participants with psychosis were randomised to either: ten sessions of ACT plus treatment as usual (TAU) or TAU alone...

  2. Postictal psychosis: presymptomatic risk factors and the need for further investigation of genetics and pharmacotherapy

    Bromfield Edward B; Lafayette Jennifer M; Morrow Eric M; Fricchione Gregory

    2006-01-01

    Abstract Background Postictal psychosis (PIP), an episode of psychosis occurring after a cluster of seizures, is common and may be associated with profound morbidity, including chronic psychosis. Symptoms are often pleomorphic, involving a range of psychotic symptoms, including hallucinations and disorders of thought. PIP is treatable and may be averted if presymptomatic risk factors are considered in susceptible patients and treatment is initiated. Case presentation In this report, we presen...

  3. The prevalence of psychosis in epilepsy; a systematic review and meta-analysis

    Clancy, Maurice J.; Clarke, Mary C.; Connor, Dearbhla J; Cannon, Mary; Cotter, David R.

    2014-01-01

    BACKGROUND: Epilepsy has long been considered to be a risk factor for psychosis. However there is a lack of consistency in findings across studies on the effect size of this risk which reflects methodological differences in studies and changing diagnostic classifications within neurology and psychiatry. The aim of this study was to assess the prevalence of psychosis in epilepsy and to estimate the risk of psychosis among individuals with epilepsy compared with controls. METHODS: A systemat...

The main aim of our study was to investigate the ability of these biomarkers to predict treatment response at 12 weeks follow-up in first episode psychosis.METHODS: In a longitudinal study, we collected saliva and blood samples in 68 first episode psychosis patients (and 57 controls) at baseline and assessed response to clinician-led antipsychotic treatment after 12 weeks. Moreover, w...

  6. Impact of Interpersonal Trauma on the Social Functioning of Adults With First-Episode Psychosis

    Stain, H. J.; Brønnick, K.; Hegelstad, W.T.V.; Joa, I.; Johannessen, J.O.; Langeveld, J.; Mawn, L.; Larsen, T.K.

    2013-01-01

    Background: Social functioning is an important treatment outcome for psychosis, and yet, we know little about its relationship to trauma despite high rates of trauma in people with psychosis. Childhood trauma is likely to disrupt the acquisition of interpersonal relatedness skills including the desire for affiliation and thus lead to impaired social functioning in adulthood. Aims: We hypothesized that childhood trauma would be a predictor of poor social functioning for adults with psychosis a...

    Although childhood trauma is generally considered to be a risk factor for later development of psychosis, the influence of trauma on the specific presentation of psychosis symptoms in high-risk and first-episode samples remains unclear. The current study aims to investigate the association of trauma with psychosis and psychosis-risk symptoms among patients with early indications of psychosis as well as in a comparison group receiving mental health services for non-psychosis concerns. Participants (N=125) were assessed for history of exposure to trauma using the KSADS-PL and psychosis-risk symptoms using the Structured Interview for Psychosis-Risk Syndromes (SIPS). Individuals were categorized as "clinical high risk/early psychosis" or "low-risk for psychosis" on the basis of SIPS criteria. The association of traumatic events with specific symptoms was explored within each group. Exposure to one or more traumatic events was more common within the early psychosis group (85%) relative to the low-risk group (65%). Within both groups, trauma significantly correlated with the severity of clinician-rated positive - but not negative, disorganized, or general - symptoms. Within the low-risk group, there was a significant association between violent traumas and heightened suspiciousness. Within the early psychosis group, both violent and non-violent traumas predicted elevated grandiosity. The prevalence of traumatic events within this adolescent and young adult clinical sample was high. Trauma history significantly predicted greater positive symptoms. The apparent influence of trauma exposure on specific symptoms was unique in each group. PMID:27107632

  8. Sudden psychotic episode probably due to meningoencephalitis and Chlamydia pneumoniae acute infection

    Canas Nuno

    2005-09-01

    Full Text Available Abstract Background Since 9% to 20% of all cases of acute psychosis presenting to an Emergency Department (ED are due to a general medical condition, cautious medical workup should be mandatory in such patients. Differential diagnosis must consider conditions as diverse as renal failure or CNS infection. Acute Chlamydia pneumoniae infection usually causes a self-limited respiratory syndrome. Rarely, acute neurological complications occur, with acute meningoencephalitis most frequently reported. Diagnosis requires a high level of suspicion and is difficult to confirm. Case report We describe a 22 year-old female Caucasian who, three days after a mild pharingitis, developed an acute psychosis with exuberant symptoms interspersed with periods of lucidity, in a background of normal consciousness and orientation. Initial medical and imagiological workup were inconclusive. After 20 days of unsuccessful treatment with antipsychotics she developed a high fever and was re-evaluated medically. Lumbar puncture revealed an inflammatory cerebrospinal fluid. MRI showed irregular thickening and nodularity of the lateral ventricles' lining. An anti-Chlamydia pneumoniae IgM antibody titter of 85 IU/ml was detected. All symptoms cleared after treatment with antibiotics and corticosteroids. Conclusion This is, to our knowledge, the first reported case of acute CP-associated meningoencephalitis manifesting as an acute psychotic episode. It illustrates the principle that non-organic psychiatric syndromes must remain a diagnosis of exclusion in first-time acute psychosis.

  10. The association between serum creatine kinase, mood and psychosis in inpatients with schizophrenia, bipolar and schizoaffective disorders.

    Hollander, Sarah; Hochman, Eldar; Shoval, Gal; Taler, Michal; Trommer, Sharon; Hermesh, Haggai; Weizman, Abraham; Krivoy, Amir

    2016-04-30

    Previous studies demonstrated levels of serum CK (sCK) in the majority of patients undergoing acute psychosis. Records of 1054 patients hospitalized in Geha Mental Health Center during the study period were analyzed. Of them, 743 have been diagnosed with schizophrenia (Sz), 170 with schizoaffective disorder (SzA), and 158 with bipolar disorder (BP-I). Baseline sCK and PANSS values were obtained from each patient upon admission. Our results show that LnsCK is higher in patients with BP-I in comparison with patients with SZ, but not significantly different compared to patients with SzA. A multivariate analysis using linear regression model in which LnsCK was predicted by factors such as PANSS-total and sub-scores, IM injection, BMI, gender, and age among patients at each admission, revealed that PANSS-depression was inversely associated with LnsCK level in SzA and BP-I and not in SZ. A positive association was found between PANSS-total and sCK in SzA and BP-I; however, PANSS-positive scores correlated with sCK only in SzA. After controlling for confounders, it seems that sCK level is associated with the both affective and psychotic components. Serum CK may serve as a biomarker for affective exacerbation rather than psychosis. PMID:27086253

  11. Strategies to deal with comorbid physical illness in psychosis.

    Docherty, M; Stubbs, B; Gaughran, F

    2016-06-01

    Individuals with serious mental illnesses such as psychosis still experience higher mortality rates than the general population, decades after data have linked the gap to increased rates of physical illness, delayed diagnosis, low treatment rates and worse outcomes from treatment received. The nature of the relationship between psychosis and comorbid physical illness is complex. Multiple strategies directed at different levels of disease process, health care systems and stakeholder culture are likely required to make sustained progress in reducing the mortality gap. Evidence for strategies that effectively reduce the burden of physical co-morbidity and lead to improved health outcomes are still in their infancy but growing at a reassuringly fast rate. This editorial considers the existing evidence base and makes suggestions for the development and future direction of this urgent research agenda and how this knowledge can be implemented in clinical practice.

  12. Positive and negative caregiver experiences in first-episode psychosis

    Jansen, Jens Einar; Lysaker, Paul H.; Harder, Susanne;

    2014-01-01

    Objectives While caregivers of persons with first-episode psychosis often report a range of negative experiences, little is known about what psychological factors are involved. The aim of this study was to examine how caregivers' general wellbeing, emotional overinvolvement and metacognition...... influenced their reports of both positive and negative caregiving experiences. Design A prospective consecutive cross-sectional study. Methods Forty caregivers of patients with first-episode psychosis were interviewed using semi-structured interview and questionnaires. Results Greater levels of distress...... and overinvolvement were associated with more negative experiences of caregiving while greater metacognitive capacity was associated with more positive experiences of caregiving. Conclusions The experience of positive and negative aspects of caregiving seems to be associated with different variables. Greater...

  13. Empathy in individuals clinically at risk for psychosis

    Derntl, B.; Michel, T. M.; Prempeh, P.;

    2015-01-01

    Background Empathy is a basic human ability, and patients with schizophrenia show dysfunctional empathic abilities on the behavioural and neural level. Aims These dysfunctions may precede the onset of illness; thus, it seems mandatory to examine the empathic abilities in individuals at clinical...... high risk for psychosis. Method Using functional magnetic resonance imaging, we measured 15 individuals at clinical high risk of psychosis (CHR group) and compared their empathy performance with 15 healthy volunteers and 15 patients with schizophrenia. Results Behavioural data analysis indicated no...... significant deficit in the CHR group. Functional data analysis revealed hyperactivation in a frontotemporoparietal network including the amygdala in the CHR group compared with the other two groups. Conclusions Despite normal behavioural performance, the CHR group activated the neural empathy network...

  14. Meditation and psychosis. A trigger or a cure?

    Krzysztof Dyga

    2015-06-01

    Full Text Available The article is a review and an analysis of studies concerning usage of meditation techniques in psychiatry and psychotherapy. A brief history and characteristic of meditation is presented, with emphasis on mindfulness meditation, which is a variation most widely used for health reasons. On the other hand, potential „side effects” of meditational practices are also brought into attention. The authors focus mostly on meditation's links to psychosis, describing both conditions in which meditation may cause decompensation, as well as presenting research on the effects o  modified meditation techniques implementation among psychotic patients. In order to better understand the phenomena described the authors interpret meditation's effects using both psychodynamic and cognitive theories. Presented studies suggest that in certain circumstances meditation may trigger psychosis, but they also show that interventions based on mindfulness may play an important clinical role in the alleviation of symptoms during psychotic episodes.

  15. Suicidal behavior and mortality in first-episode psychosis

    Nordentoft, Merete; Madsen, Trine; Fedyszyn, Izabela

    2015-01-01

    particularly high during the first year of the initial contact with mental health services, being almost twice as high as in the later course of the illness. The most consistently reported risk factor for suicide among people with psychotic disorders is a history of attempted suicide and depression. Suicide...... risk in psychosis in Denmark decreased over time, most likely because of improved quality of inpatient and outpatient services. There is a high proportion of young people with first-episode psychosis who attempted suicide before their first contact with mental health services. This finding suggests...... that the mortality rates associated with psychotic disorders may be underreported because of suicide deaths taking place before first treatment contact. However, currently, no data exist to confirm or refute this hypothesis. Attempted suicide can be an early warning sign of later psychotic disorder...

  19. Mefloquine use, psychosis, and violence: A retinoid toxicity hypothesis

    Mawson, Anthony R

    2013-01-01

    Mefloquine use has been linked to severe gastrointestinal and neuropsychiatric adverse effects, including cognitive disturbances, anxiety, depression, psychosis, and violence. The adverse effects of the drug are thought to result from the secondary consequences of hepatocellular injury; in fact, mefloquine is known to cause a transient, anicteric chemical hepatitis. However, the mechanism of mefloquine-associated liver damage and the associated neuropsychiatric and behavioral effects of the d...

  1. Health beliefs and carer burden in first episode psychosis

    Patel, Maya; Chawla, Rajan; Krynicki, Carl R; Rankin, Philip; Upthegrove, Rachel

    2014-01-01

    Background Carer burden is high during First Episode Psychosis (FEP) and evidence suggests that this is a predictor of poor long-term outcome. However our understanding of factors associated with higher burden is poor. We propose that carers’ cultural backgrounds and health belief models will influence their perceived burden of care, over and above that explained by severity of illness. Methods Patients with FEP and their primary Carers were recruited from the Early Intervention Service. Pati...

    2012-01-01

    Psychotic depression (PD) is classified as a subtype of severe depression in the current diagnostic manuals. Accordingly, it is a common conception among psychiatrists that psychotic features in depression arise as a consequence of depressive severity. The aim of this study was to determine wheth...... the severity of depressive and psychotic symptoms correlate in accordance with this "severity-psychosis" hypothesis and to detect potential differences in the clinical features of PD and non-psychotic depression (non-PD)....

    2016-01-01

    Psychotic disorders such as schizophrenia entail substantial suffering for the affected individuals and their networks. Traditionally, these disorders come as diagnosable entities that you either have or have not. However, recent epidemiological research has shown that symptoms of psychotic disorder, i.e., psychotic experiences, are common in the general population, especially during adolescence, and that these experiences are correlated with the development of psychosis. Thus, the traditiona...

  5. An unusual presentation of brief recurrent psychosis: a case report

    Krishnamurthy CN; Sanivarapu, Sravanti L.

    2012-01-01

    Background: Although the term "zycloiden psychosen" was first used by Karl Kleist in 1926 to group together disorders, which had presented with sudden onset, brief episodic course, polymorphous psychotic symptoms and good inter-episode recovery, its origin can be traced back to 1880s. Despite its existence in the community, for so long, the diagnosis of cycloid psychosis is only seldom made, making it a unique disorder. Hence, there seems to be lack of awareness of this rare entity even among...

    Onset of psychosis may be associated with abnormal adolescent neurodevelopment. Here we examined the neurocognitive profile of first-episode, adolescent onset psychosis (AOP) as compared to typically developing adolescents, and asked whether neurocognitive performance varied differentially as a function of age in the cases compared with controls.…

    Frequency and mechanisms underlying the association between narcolepsy type 1 (NT1) and psychosis remain unclear with potential role for a common immune pathway. We estimated the frequency of psychosis and its characteristics in NT1 at two European sleep centers (France, n = 381; Spain, n = 161) and measured IgG autoantibodies that recognize the GluN1 subunit of the NMDAR in 9 patients with NT1 with psychosis, and 25 NT1 patients without psychosis. Ten NT1 patients (6 in France, 4 in Spain) were diagnosed with comorbid psychosis, a frequency of 1.8%. One patient reported psychotic symptoms few months before narcolepsy onset, two patients few months after onset, and one patient one year after onset but after modafinil introduction. The six remaining patients reported long delays between NT1 and psychosis onset. Half the patients, mostly male adults, reported onset or worsening of psychotic symptoms after medication. We found no IgG antibodies to NR1/NR2B heteromers of the NMDARs in patients with NT1 with or without psychosis. To conclude, psychosis is rare in NT1, with limited evidence for a key impact of stimulants, and no association with anti-NMDAR antibodies. However, dramatic NT1 and schizophrenia exists especially in early onset NT1, which may lead to inappropriate diagnosis and management. PMID:27143278

    Patients with Bipolar disorder smoke more than the general population. Smoking negatively impacts mortality and clinical course in Bipolar disorder patients. Prior studies have shown contradictory results regarding the impact of psychosis on smoking behavior in Bipolar disorder. We analyzed a large sample of Bipolar disorder and Schizoaffective disorder, Bipolar Type patients and predicted those with a history of psychosis would be more likely to be nicotine dependent. Data from subjects and controls were collected from the Genomic Psychiatry Cohort (GPC). Subjects were diagnosed with Bipolar disorder without psychosis (N = 610), Bipolar disorder with psychosis (N = 1544). Participants were classified with or without nicotine dependence. Diagnostic groups were compared to controls (N = 10065) using logistic regression. Among smokers (N = 6157), those with Bipolar disorder had an increased risk of nicotine dependence (OR = 2.5; P Bipolar disorder with psychosis were more likely to be dependent than Bipolar disorder patients without psychosis (OR = 1.3; P = 0.03). Schizoaffective disorder, Bipolar Type patients had more risk of nicotine dependence when compared to Bipolar disorder patients with or without psychosis (OR = 1.2; P = 0.02). Bipolar disorder patients experiencing more severity of psychosis have more risk of nicotine dependence. © 2015 Wiley Periodicals, Inc. PMID:26467098

    2016-04-01

    Synthetic cannabinoid usage has increased in the past decade. Concurrently, emergency management of associated adverse effects due to synthetic cannabinoid usage has also risen. Reported toxicities include psychosis, seizures, cardiotoxicity, acute kidney injury, and death. While cannabis was first described as a cause of acute hyperemesis in 2004, a more recent case series also describes the association between cannabinoid hyperemesis and risk of acute renal failure. Synthetic cannabinoids have also been reported to cause acute hyperemesis and acute renal failure; however, the risk of rhabdomyolysis-induced renal failure has yet to be elucidated. In this article, we report the first known case of synthetic cannabinoid hyperemesis leading to rhabdomyolysis and acute renal failure. PMID:26422191

  8. On the transmethylation hypothesis: stress, N,N-dimethyltryptamine, and positive symptoms of psychosis.

    Grammenos, Dionysios; Barker, Steven A

    2015-06-01

    Past research suggests a relationship between stress and positive symptoms of psychosis. However, the biological substrate of this relationship remains unknown. According to the transmethylation hypothesis, schizophrenia could result from a biochemical disruption in the stress mechanism. This biochemical disruption would lead to the production of a substance that would account for the symptoms of psychosis. Moreover, some studies have tested endogenous N,N-dimethyltryptamine (DMT) in the context of the transmethylation hypothesis. Stress has been found to elevate DMT levels in rodents. Also, elevated DMT levels have been associated with positive features of psychosis in psychiatric patients. Additionally, healthy participants treated with exogenous DMT experience predominantly positive symptoms of psychosis. The present paper examines endogenous DMT as a possible biological mediator of the relationship between stress and positive symptoms of psychosis. PMID:25362533

  9. Late onset radioiodine-induced hypothyroidism presenting with psychosis 14 years after treatment: a rare case

    Er, Chaozer; Sule, Ashish Anil

    2016-01-01

    Radioiodine treatment-induced hypothyroid psychosis is uncommon. Our literature search shows only three cases of hypothyroid psychosis developed within 3 months after the radioiodine treatment. Our case represents the first case of radioiodine-induced hypothyroidism presenting as psychosis much later (14 years) after the radioiodine treatment. A 60-year-old Chinese lady, with long-standing primary hypothyroidism due to the radioiodine treatment performed 14 years ago, presented with a 1-week history of hallucination, delusion and agitation. She was not on thyroid replacement. Thyroid function test done 14 years ago and again upon her admission to our facility was consistent with primary hypothyroidism. General blood tests and brain imaging were unremarkable. Her psychotic features resolved within 1 week with thyroid replacement and 9 days of antipsychotics. No further relapse of psychosis was noted. This emphasizes that radioiodine-induced hypothyroidism can go unnoticed for many years and present much later solely as psychosis. PMID:27099771

    Methamphetamine use is increasing worldwide, and the occurrence of psychosis further complicates treatment. This holds also true for Iran. The aim of the present study was to investigate possible predictors of metamphetamine-induced psychosis. 237 methamphetamine users (70.9% with psychosis; mean age: M=33.41 years) took part in the study. A psychiatric interview was performed covering socio-demographic and illness-related information. Male gender, low education, unemployment, being single, a history of mental disorders, and a higher number of previous hospitalizations predicted the occurrence of psychosis, while age and duration of metamphetamine use were excluded from the equation. Socio-demographic and mental illness-related dimension seemed suitable to predict occurrence of psychosis among metamphetamine abusers. PMID:27172885

    1986-01-01

    Acute porphyria afflicts a large kindred in Chester that stems from a marriage in 1896 that has produced 200 descendants; this is the largest porphyric kindred to be identified in the United Kingdom. Six members aged 51 or under died from the condition over the past eight years. The diagnosis of porphyria was overlooked in some as the symptoms may mimic those of other acute illnesses, so that incomplete or incorrect death certificates have been issued. Psychosis, hypertension, and renal compl...

    Full Text Available INTRODUCCIÓN Los potenciales relacionados a eventos N200 y P300 son herramientas sensibles para evaluar el funcionamiento sensorial y cognitivo. Debido a que, frecuentemente se reporta una prolongación de la latencia y una disminución de la amplitud de los componentes N200 y P300 en pacientes con esquizofrenia, estos potenciales constituyen marcadores biológicos de vulnerabilidad genética para este trastorno mental. OBJETIVO Precisar la asociación de las alteraciones en la latencia, la amplitud y la distribución topográfica de los potenciales N200 y P300 de pacientes con esquizofrenia paranoide y sus familiares sanos de primer grado, pertenecientes a familias con esquizofrenia multiplex. MÉTODOS Se utilizó un paradigma “odd-ball” auditivo para evaluar la latencia, la amplitud y la distribución topográfica de los componentes N200 y P300 en 25 pacientes con esquizofrenia paranoide (probandos, 23 familiares sanos de primer grado y 25 sujetos controles, mediante un estudio de asociación familiar en 60 familias afectadas con esquizofrenia multiplex. RESULTADOS Los probandos y sus familiares mostraron una prolongación significativa de la latencia y una disminución de amplitud de las ondas N200 y P300 cuando se compararon con los sujetos sanos. De igual forma, la amplitud de los potenciales N200 y P300 resultó significativamente disminuida en regiones temporales del hemisferio izquierdo de los probandos y sus familiares con respecto al grupo control. CONCLUSIONES En concordancia con resultados de otros investigadores, este estudio sugiere que, la prolongación de latencia, la disminución de amplitud y las alteraciones en la distribución topográficas detectadas en regiones temporales de los potenciales N200 y P300, pueden constituir por su elevada asociación familiar, marcadores de rasgo para la esquizofrenia paranoide.

  15. Ayahoasca: an experimental psychosis that mirrors the transmethylation hypothesis of schizophrenia.

    1999-04-01

    The experimental psychosis observed after drinking Ayahoasca, a South American hallucinogenic beverage from the Amazon Indians, reproduces the pathologic transmethylation theory of schizophrenia. This theory postulates a decrease in the monoamine oxidase (MAO) activity, which results in the accumulation of methylated indolealkylamines, such as bufotenin (5-hydroxy-N,N-dimethyltryptamine), N,N-dimethyltryptamine (DMT) and 5-methoxy-N,N-dimethyltryptamine. These substances are strong hallucinogens as has been previously confirmed experimentally. On the other hand, it is known that Ayahoasca is a beverage usually prepared by boiling two plants, one of them rich in beta-carbolines, which are naturally occurring strong inhibitors of MAO, and the other with high quantities of DMT. This particular combination reproduces what is supposed to occur under pathologic conditions of different psychoses. The effects of Ayahoasca were studied in subjects, assessing urine levels of DMT by gas chromatography-mass spectrometry (GC-MS) before and after the intake of the beverage. The results of this study confirm that the hallucinogenic compounds detected in the healthy subjects' (post-Hoasca, but not before) urine samples are the same as those found in samples from acute psychotic unmedicated patients. The chemical composition of the Ayahoasca beverage, and of the plant material used for its preparation are also reported as well as psychometric and neuroendocrine subject parameters. PMID:10350367

This condition is known as neuroleptic-induced deficit syndrome (NIDS, which includes apathy, lack of initiative, anhedonia, indifference, blunted affect, and reduced insight into disease. Although this old concept now appears almost forgotten, neuroleptics, whether typical or atypical, can make depression or bipolar disorder resemble other more refractory conditions, readily leading to mistaken diagnosis and inappropriate treatment. The authors describe three cases of NIDS superimposed on depressive phase in bipolar disorder with psychosis, where the attending psychiatrist’s failure to recognize NIDS prevented patients from receiving effective treatment and achieving remission. All cases achieved remission after reduction of neuroleptics and intensive therapy, including electroconvulsive therapy, for bipolar depression. The concept of NIDS was originally introduced for schizophrenia, and it has rarely been highlighted in other diseases. In recent years, however, atypical antipsychotics are being more often administered to patients with bipolar disorder. Psychiatrists, therefore, should also remember and exercise caution regarding NIDS in the pharmacotherapy of bipolar disorder with and without psychosis. The authors believe that the concept of NIDS needs to be reappraised in current psychiatry.

  17. Anti-NMDA receptor encephalitis, autoimmunity, and psychosis.

    Kayser, Matthew S; Dalmau, Josep

    2016-09-01

    Anti-N-methyl-d-aspartate receptor (NMDAR) encephalitis is a recently-discovered synaptic autoimmune disorder in which auto-antibodies target NMDARs in the brain, leading to their removal from the synapse. Patients manifest with prominent psychiatric symptoms - and in particular psychosis - early in the disease course. This presentation converges with long-standing evidence on multiple fronts supporting the glutamatergic model of schizophrenia. We review mechanisms underlying disease in anti-NMDAR encephalitis, and discuss its role in furthering our understanding of neural circuit dysfunction in schizophrenia. PMID:25458857

    Leivada, Evelina

    2016-03-23

    The absence of co-occurrence of schizophrenia with congenital/early blindness (CB) has led to the claim that CB confers protection against schizophrenia. It has recently been shown that the protective effects are particularly reinforced in cases of CB of cortical origin, since cases of CB of peripheral origin and schizophrenia in fact exist. The present work shows that the protection extends to psychosis more broadly and describes the brain basis of the protective mechanism and its relation to the language faculty and the language areas of the brain.

    Full Text Available Psychotic disorders are among the most complex medical conditions. Longitudinal cohort studies may offer further insight into determinants of functional outcome after a psychotic episode. This paper describes the Psychosis Recent Onset in GRoningen Survey (PROGR-S that currently contains data on 1076 early-episode patients with psychosis, including symptoms, personality, cognition, life events and other outcome determinants. Our goal in this report is to give an overview of PROGR-S, as a point of reference for future publications on the effect of cognition, personality and psychosocial functioning on outcomes. PROGR-S contains an extensive, diagnostic battery including anamnesis, biography, socio-demographic characteristics, clinical status, drug use, neuropsychological assessment, personality questionnaires, and physical status tests. Extensive follow-up data is available on psychopathology, physical condition, medication use, and care consumption. Sample characteristics were determined and related to existing literature. PROGR-S (period 1997-2009, n = 718 included the majority of the expected referrals in the catchment area. The average age was 27 (SD = 8.6 and two-thirds were male.

  2. Psychosis, Socioeconomic Disadvantage and Health Service Use in South Australia: Findings from the Second Australian National Survey of Psychosis

    2015-11-01

    Full Text Available The association between mental illness and poor physical health and socioeconomic outcomes has been well established. In the twenty-first century, the challenge of how mental illnesses such as psychosis are managed in the provision of public health services remains complex. Developing effective clinical mental health support and interventions for individuals requires a coordinated and robust mental health system supported by social as well as health policy that places a priority on addressing socioeconomic disadvantage in mental health cohorts. This paper thus examines the complex relationship between socioeconomic disadvantage, family/social supports, physical health and health service utilisation in a community sample of 402 participants diagnosed with psychosis. The paper utilises quantitative data collected from the 2010 Survey of High Impact Psychosis research project conducted in a socioeconomically disadvantaged region of Adelaide, South Australia. Participants (42% female provided information about socio-economic status, education, employment, physical health, contact with family and friends, and health service utilisation. The paper highlights that socio-economic disadvantage is related to increased self-reported use of emergency departments, decreased use of general practitioners for mental health reasons, higher body mass index, less family contact and less social support. In particular, the paper explores the multifaceted relationship between socioeconomic disadvantage and poor health confronting individuals with psychosis, highlighting the complex link between socioeconomic disadvantage and poor health. It emphasizes that mental health service usage for those with higher levels of socioeconomic disadvantage differs from those experiencing lower levels of socioeconomic disadvantage. The paper also stresses that the development of health policy and practice that seeks to redress the socioeconomic and health inequalities created by

  4. Anti-NMDA Receptor Encephalitis Presenting as an Acute Psychotic Episode in a Young Woman: An Underdiagnosed yet Treatable Disorder

    Shikma Keller

    2014-01-01

    Full Text Available Anti-NMDA receptor (NMDAR encephalitis is a recently identified autoimmune disorder with prominent psychiatric symptoms. Patients usually present with acute behavioral change, psychosis, catatonic symptoms, memory deficits, seizures, dyskinesias, and autonomic instability. In female patients an ovarian teratoma is often identified. We describe a 32-year-old woman who presented with acute psychosis. Shortly after admission, she developed generalized seizures and deteriorated into a catatonic state. Although ancillary tests including MRI, electroencephalogram, and cerebrospinal fluid (CSF analysis were unremarkable, the presentation of acute psychosis in combination with recurrent seizures and a relentless course suggested autoimmune encephalitis. The patient underwent pelvic ultrasound which disclosed a dermoid cyst and which led to an urgent cystectomy. Plasmapheresis was then initiated, yielding partial response over the next two weeks. Following the detection of high titers of anti-NMDAR antibodies in the CSF, the patient ultimately received second line immunosuppressive treatment with rituximab. Over several months of cognitive rehabilitation a profound improvement was eventually noted, although minor anterograde memory deficits remained. In this report we call for attention to the inclusion of anti-NMDAR encephalitis in the differential diagnosis of acute psychosis. Prompt diagnosis is critical as early immunotherapy and tumor removal could dramatically affect outcomes.

  5. Cognitive and neural models of threat appraisal in psychosis: A theoretical integration.

    Underwood, Raphael; Kumari, Veena; Peters, Emmanuelle

    2016-05-30

    Cognitive models of psychosis propose that maladaptive appraisals of anomalous experiences contribute to distress and disability in psychosis. Attentional, attributional and reasoning biases are hypothesised to drive these threat-based appraisals. Experimental and self-report data have provided support for the presence of these biases in psychosis populations, but recently there have been calls for neurobiological data to be integrated into these findings. Currently, little investigation has been conducted into the neural correlates of maladaptive appraisals. Experimental and neuroimaging research in social cognition employing threatening stimuli provide the closest equivalent of maladaptive appraisal in psychosis. Consequently, a rapprochement of these two literatures was attempted in order to identify neural networks relevant to threat appraisal in psychosis. This revealed overlapping models of aberrant emotion processing in anxiety and schizophrenia, encompassing the amygdala, insula, hippocampus, anterior cingulate cortex, and prefrontal cortex. These models posit that aberrant activity in these systems relates to altered emotional significance detection and affect regulation, providing a conceptual overlap with threat appraisal in psychosis, specifically attentional and attributional biases towards threat. It remains to be seen if direct examination of these biases using neuroimaging paradigms supports the theoretical integration of extant models of emotion processing and maladaptive appraisals in psychosis.

  6. Psychotic-like experiences in the general population: characterizing a high-risk group for psychosis.

    Kelleher, I

    2011-01-01

    Recent research shows that psychotic symptoms, or psychotic-like experiences (PLEs), are reported not only by psychosis patients but also by healthy members of the general population. Healthy individuals who report these symptoms are considered to represent a non-clinical psychosis phenotype, and have been demonstrated to be at increased risk of schizophrenia-spectrum disorder. Converging research now shows that this non-clinical psychosis phenotype is familial, heritable and covaries with familial schizophrenia-spectrum disorder. A review of the research also shows that the non-clinical phenotype is associated extensively with schizophrenia-related risk factors, including social, environmental, substance use, obstetric, developmental, anatomical, motor, cognitive, linguistic, intellectual and psychopathological risk factors. The criterion and construct validity of the non-clinical psychosis phenotype with schizophrenia demonstrates that it is a valid population in which to study the aetiology of psychosis. Furthermore, it suggests shared genetic variation between the clinical and non-clinical phenotypes. Much remains to be learned about psychosis by broadening the scope of research to include the non-clinical psychosis phenotype.

  7. Increased risk of psychosis in patients with hearing impairment: Review and meta-analyses.

    Linszen, Mascha M J; Brouwer, Rachel M; Heringa, Sophie M; Sommer, Iris E

    2016-03-01

    Several studies suggest hearing impairment as a risk factor for psychosis. Hearing impairment is highly prevalent and potentially reversible, as it can be easily diagnosed and sometimes improved. Insight in the association between hearing impairment and psychosis can therefore contribute to prevention of psychosis. This paper provides meta-analyses of all epidemiologic evidence on the association between hearing impairment and psychosis and summarizes mechanisms that potentially underlie this relationship. Meta-analyses showed an increased risk of hearing impairment on all psychosis outcomes, such as hallucinations (OR 1.40(95%CI 1.18-1.65; n=227,005)), delusions (OR 1.55(95%CI 1.36-1.78; n=250,470)), psychotic symptoms (OR 2.23(95%CI 1.83-2.72; n=229,647) and delirium (OR 2.67(95%CI 2.05-3.48; n=12,432). Early exposure to hearing impairment elevated the risk of later development of schizophrenia (OR 3.15(95%CI 1.25-7.95; n=50,490)). Potential mechanisms underlying this association include loneliness, diminished theory of mind, disturbances of source monitoring and top-down processing and deafferentiation. Early assessment and treatment of hearing impairment in patients with (high risk of) psychosis may be essential in psychosis treatment and prevention. PMID:26743858

Psychiatrists, therefore, should also remember and exercise caution regarding NIDS in the pharmacotherapy of bipolar disorder with and without psychosis. The authors believe that the concept of NIDS needs to be reappraised in current psychiatry. PMID:26893564

  9. How should we intervene in psychosis risk syndromes?

    Jijun WANG; Kaida JIANG; Tianhong ZHANG; Huijun LI; Kristen WOODBERRY; Larry SEIDMAN

    2013-01-01

    Research diagnostic instruments such as the Structured Interview for Prodromal Syndromes (SIPS) are now able to reliably identify individuals with different types of psychosis risk syndromes (PRS). About one-third of individuals with PRS convert to a diagnosable psychotic disorder within three years of the initial assessment. Currently available randomized controlled trials of interventions aimed at reducing the rate of psychotic conversion of PRS are promising, but they are too small and too short in duration to provide definitive conclusions about effectiveness. Given the high level of false positives (i.e., most individuals with PRS do not progress to frank psychosis) and the lack of definitive evidence about effectiveness, we recommend a staged approach to intervention in PRS that only uses antipsychotic medication after other, more benign approaches have been tried. At present the best approach appears to be to develop high-quality casemanagement systems for individuals with PRS that provide close follow-up, psychoeducation and psychosocial support to patients and family members, and, possibly, psychotherapeutic and pharmacological treatments (with antipsychotic medications or neuroprotective agents). The effectiveness of these proposed interventions needs to be tested in large randomized controlled trials that follow up subjects for at least three years.

    2007-01-01

    The Palau Early Psychosis Study (PEPS) was designed to examine the pathogenesis of early psychosis in a high-risk population isolate. This paper describes the characteristics of our community-based, non-help seeking sample of 404 Palauan adolescents and quantifies the presence of early psychosis by level of genetic risk. The sample included 53 offspring of a schizophrenic parent designated as "Genetically Highest Risk" (GHR+) and 68 nieces/nephews of sib-pairs/trios, designated as "Genetically High Risk" (GHR). The remaining subjects were recruited through a high school survey that identified 62 "Genetically Moderate Risk" (GMR) adolescents with an affected second or third degree relative and 221 "Genetically Low Risk" (GLR) subjects with no close affected relatives. The GLR adolescents included 117 symptomatic or "Clinically High Risk" (CHR) adolescents and 104 asymptomatic normal controls. Based on a modified K-SADS-PL assessment, we identified 221 adolescents with early psychosis, 62 or 28% of whom had already transitioned to a psychotic disorder. Together, the two highest risk groups contributed 31% of the adolescent-onset psychosis cases and 27% of the prodromals. More than half of the early psychosis cases (53%) were GLR adolescents. The mean age of onset for DSM-IV psychosis was 12.9 years, and males transitioned at an earlier age than females. Our results indicate that Palauan adolescents, even GLR adolescents with no close affected relatives, have elevated rates of early psychosis. These young subjects can contribute valuable information about the familial transmission of schizophrenia, the developmental course of the illness, and rates of transition to frank psychosis.

    2008-06-01

    Recent interest has focused on the association between cannabis use and risk of psychosis. In the largest unselected, population-based study on this topic to date, we examined cannabis use and prodromal symptoms of psychosis at age 15-16 years among 6330 adolescents. Those who had tried cannabis (n=352; 5.6% of the total sample) were more likely to present three or more prodromal symptoms even after controlling for confounders including previous behavioural symptoms (OR=2.23; 95% CI 1.70-2.94). A dose-response effect was seen. We conclude that cannabis use is associated with prodromal symptoms of psychosis in adolescence. PMID:18515902

    2013-01-01

    Recently, shortening of the duration of untreated psychosis (DUP) and intensive treatment within the critical period are taken as determinants of a favorable prognosis, and various service systems and treatment approaches for early intervention in schizophrenia have been proposed in the world. At the Toho University Omori Medical Center, Early Psychosis Unit "Il Bosco" was established as an intervention service from the viewpoint of preventing full-blown psychosis at the prodromal stage, where cognitive training for a direct therapeutic approach to brain function and psychosocial treatment for patients at puberty and adolescence are administered. In this article, we introduce the practice at "Il Bosco" and consider future prospects. PMID:23691804

  14. Impact of childhood trauma on risk of relapse requiring psychiatric hospital admission for psychosis.

    Petros, N; Foglia, E; Klamerus, E; Beards, S; Murray, R M; Bhattacharyya, S

    2016-08-01

    Relapse in psychosis typically necessitates admission to hospital placing a significant financial burden on the health service. Exposure to childhood trauma is associated with an increased risk of psychosis, however, the extent to which this influences relapse is unclear. This report summarises current research investigating the influence of childhood trauma on relapse requiring psychiatric hospital admission for psychosis. Seven studies were included; two revealed a positive association between childhood trauma and relapse admission, two studies found a negative relationship and three found no significant difference. Inconsistent current evidence suggests a need for further research in this area. PMID:27151070

  15. Infantile autism: a chronic psychosis since infancy due to synaptic pruning of the supplementary motor area.

    Saugstad, Letten F

    2011-01-01

    The rise in infantile autism, learning problems, cognitive decline with age, Alzheimer's, Parkinson's diseases and the SIDS epidemic, has a common cause in the rising dietary deficit in Omega-3 brain-food. This paper suggests that aside from the wider concept of autism spectrum disorders (ASD) and pervasive developmental disorders (PDD), the rise in infantile autism (IA) in the last decade is the effect of deficient brain-food (Omega-3). The consequent delay of development, prolongs the 2nd regressive event in infancy to pruning of the centre in the Medial Frontal Lobe System that connects hippocampus and singulum. With a consequently defective supplementary motor area (SMA), the Delayed Response Function is affected leading to persistent psychosis. Post-pubertal episodic psychoses are associated with acute reduction of excitation, a risk of breakdown of circuitry, insufficient fill-in mechanisms, and silent spots. An acute psychosis occurs if the silent spots compromise SMA. Only two brain areas have continuous neurogenesis, indicating their important functions: the Hippocampus and Olfactory Bulb that belongs to the lateral frontal lobe system essential to survival. Concerned with necessity of action in response to the environment, it relies upon short-term memory and acute feedback mechanisms influenced by emotion and motivation from the external world. In contrast, the medial frontal lobe network is controlled by feed-forward predictive mechanisms related to storage of information The Delayed Response Function is mastered at 7 months, when 2nd event occurs with pruning of axons and dendrites. An abolished or defective delayed response function seriously incapacitates an individual: a defective "social brain" with an inability for conscious action and to communicate, predominates in IA. There is a near lack of speech, despite normal vision and hearing in the minority without marked adversity in pregnancy, at delivery or in infancy. The recent rise in IA despite

    Full Text Available Aim. Amphetamine and its derivates can induce, usually after many intoxications, schizophrenia-like psychosis. These disorders appeared only in part patients with amphetamine dependence. Aim of the study was to establish prevalence of selective risk factors of schizophrenia development in amphetamine users: 1 with amphetamine – induced schizophrenia – like psychosis, 2 with schizophrenia, and 2 without psychotic symptoms. Material. In the study 3 groups of subjects were included: 30 amphetamine users with amphetamine induced schizophrenia – like psychosis, 30 amphetamine users with schizophrenia and 30 amphetamine users without psychotic symptoms (37 female and 53 male in mean age=17.78 years . Methods. Amphetamine dependence, schizophrenia and schizophrenia-like psychosis induced amphetamine were diagnosed according to ICD-10 criteria after at least 1 year of amphetamine abstinence. The next procedure was used: 1 Structured interview with subjects and their mothers/caregivers regarding: a amphetamines use (duration of abuse, doses of psychoactive substance b family history of psychosis (especially schizophrenia 2 The Questionnaire of Child Development for assessment of prevalence of selected risk factors of schizophrenia development 3 The Premorbid Adjustment Scale (Cannon – Spoor for assessment of premorbid psychosocial functioning in thelast year before psychosis. Conclusions. Amphetamines users with amphetamine-induced psychosis were more similar in prevalence of selective risk factors of schizophrenia development to subjects with schizophrenia and amphetamine dependence than to amphetamine users without psychosis. Amphetamine-induced psychosis developed more frequently in amphetamine users who used higher amphetamine doses and with familial history of psychosis.

  19. Attachment relationships of preschool-aged children of mothers with HIV and HIV-related psychosis.

    Spies, R; Sterkenburg, P S; van Rensburg, E; Schuengel, C

    2016-10-01

    Children from mothers with HIV-related psychosis are frequently raised in challenging contexts, yet the extent to which these children grow up in insecure or disordered attachment relationships is unknown. Using the Strange Situation Procedure the distribution of attachment relationships of children from mothers with HIV and psychosis (n = 45) was compared with children from mothers with HIV without psychosis (n = 41). No significant differences in the distributions were found between the two groups and attachment was not associated with specific psychotic symptomatology. Security of attachment was associated with more people providing the mother with emotional support, but only in the psychosis group. Disordered attachment (24%) was more often found in the total sample than in studies with other normal and high risk populations. Recommendations were made for future research about factors facilitating resilience in the children and on interventions increasing emotional support for affected mothers. PMID:27219712

  3. Psychosis, Delusions and the "Jumping to Conclusions" Reasoning Bias: A Systematic Review and Meta-analysis.

    Dudley, Robert; Taylor, Peter; Wickham, Sophie; Hutton, Paul

    2016-05-01

    We did a systematic review and meta-analysis to investigate the magnitude and specificity of the "jumping to conclusions" (JTC) bias in psychosis and delusions. We examined the extent to which people with psychosis, and people with delusions specifically, required less information before making decisions. We examined (1) the average amount of information required to make a decision and (2) numbers who demonstrated an extreme JTC bias, as assessed by the "beads task." We compared people with psychosis to people with and without nonpsychotic mental health problems, and people with psychosis with and without delusions. We examined whether reduced data-gathering was associated with increased delusion severity. We identified 55 relevant studies, and acquired previously unpublished data from 16 authors. People with psychosis required significantly less information to make decisions than healthy individuals (k= 33,N= 1935,g= -0.53, 95% CI -0.69, -0.36) and those with nonpsychotic mental health problems (k= 13,N= 667,g= -0.58, 95% CI -0.80, -0.35). The odds of extreme responding in psychosis were between 4 and 6 times higher than the odds of extreme responding by healthy participants and participants with nonpsychotic mental health problems. The JTC bias was linked to a greater probability of delusion occurrence in psychosis (k= 14,N= 770, OR 1.52, 95% CI 1.12, 2.05). There was a trend-level inverse association between data-gathering and delusion severity (k= 18;N= 794;r= -.09, 95% CI -0.21, 0.03). Hence, nonaffective psychosis is characterized by a hasty decision-making style, which is linked to an increased probability of delusions. PMID:26519952

  4. Early Prodromal Symptoms Can Predict Future Psychosis in Familial High-Risk Youth

    Tandon, Neeraj; Montrose, Debra; Shah, Jai; Rajarethinam, RP; Diwadkar, Vaibhav A.; Keshavan, Matcheri S.

    2011-01-01

    Background Efforts to predict psychosis in individuals at high risk for schizophrenia have focused on the identification of sub-threshold clinical criteria and neurobiological markers, including neuropsychological assessment, structural and functional brain imaging, and psychophysiological testing. We sought to evaluate the relative utility of psychosis proneness measures for prospective prediction of psychotic disorders in a group of young relatives at familial risk for schizophrenia. Methods We examined the receiver operating characteristics of sub-threshold symptoms in predicting conversion to psychosis in a group of 97 young first- and second-degree relatives of persons with schizophrenia over a 2-year period. Towards this end, we utilized the Structured Interview of Prodromal Symptoms to derive measures of two of the four Scale of Prodromal Symptoms subscales (positive and disorganized) and the Chapman Magical Ideation and Perceptual Aberration scales. These four measures were, together, taken to reflect a putative index of psychosis proneness. Results Eleven of the 97 subjects developed a psychotic disorder over 2 years of follow-up. Seventeen of the 97 subjects tested positive on this index of psychosis proneness at baseline and of these 10 converted to psychosis. The sensitivity and specificity of the test were 91 percent and 92 percent respectively. The positive predictive value of the test was 59 percent and its negative predictive value was 99 percent. Addition of measures of cognitive or social function to the index decreased its predictive ability, reducing its specificity and/or sensitivity. Conclusions A relatively simple set of clinical measures can be utilized to prospectively identify familial high-risk individuals who convert to psychosis with high specificity and sensitivity. Implications for the proposed addition of an “Attenuated Psychosis Syndrome” in DSM-5 are discussed. PMID:22056319

    Background. Help-seeking is a concept of growing interest in the context of psychosis and the move towards early intervention and community-based service models. Despite a preponderance of first episode studies in this field, help-seeking is also of clinical relevance to adults with more chronic psychosis in the face of spiralling patterns of relapse and diminished recovery. Recent research into attachment theory opens up new avenues for exploring aspects of relating in psyc...

    Self-determination theory (SDT) posits that human well-being depends on the satisfaction of three basic psychological needs: autonomy, competence, and relatedness. Although many scholars have suggested that SDT may be relevant to psychotic disorders, only one empirical study of SDT in individuals with psychosis has been completed to date by Breitborde and colleagues (2012). This study revealed that individuals with first-episode psychosis reported lower satisfaction of the three basic psychol...

    Depression following psychosis is common and can impact negatively on individuals’ quality of life. This study conducted post-hoc analyses on 14 participants with psychosis from a larger randomised controlled trial who presented with clinically important levels of depression at baseline. Eight of the participants received Acceptance and Commitment Therapy (ACT), whilst the remaining six individuals received treatment as usual (TAU). The focus was on investigating clinically significant change...

  11. The relationship between insight and neurological dysfunction in first-episode psychosis.

    Hill, M

    2012-04-01

    Impaired insight is commonly seen in psychosis and some studies have proposed that is a biologically based deficit. Support for this view comes from the excess of neurological soft signs (NSS) observed in patients with psychoses and their neural correlates which demonstrate a degree of overlap with the regions of interest implicated in neuroimaging studies of insight. The aim was to examine the relationship between NSS and insight in a sample of 241 first-episode psychosis patients.

  12. Cognitive, Emotional, and Social Processes in Psychosis: Refining Cognitive Behavioral Therapy for Persistent Positive Symptoms

    Kuipers, Elizabeth; Garety, Philippa; Fowler, David; Freeman, Daniel; Dunn, Graham; Bebbington, Paul

    2006-01-01

    Psychosis used to be thought of as essentially a biological condition unamenable to psychological interventions. However, more recent research has shown that positive symptoms such as delusions and hallucinations are on a continuum with normality and therefore might also be susceptible to adaptations of the cognitive behavioral therapies found useful for anxiety and depression. In the context of a model of cognitive, emotional, and social processes in psychosis, the latest evidence for the pu...

    2015-12-01

    Full Text Available A young patient who presented with headache followed by positive and negative symptoms of psychosis and mutism was sent for the MRI of brain. MRI revealed a lipoma in the quardrigeminal area. We hypothesized that the neuro-vascular encasement of structures located at the upper dorsal midbrain by the lipoma caused the symptoms. A review of the current literature of quadrigeminal lipoma cases with presenting symptoms is provided. Lipoma in quardrigeminal area could give rise to symptoms of psychosis.

  17. Dimensional assessment of behavioral changes in the cuprizone short-term exposure model for psychosis.

    Kondo, Mari A; Fukudome, Daisuke; Smith, Dani R; Gallagher, Michela; Kamiya, Atsushi; Sawa, Akira

    2016-06-01

    Recent clinical studies have suggested a role for immune/inflammatory responses in the pathophysiology of psychosis. However, a mechanistic understanding of this process and its application for drug discovery is underdeveloped. Here we assessed our recently developed cuprizone short-term exposure (CSE) mouse model across behavioral domains targeting neurocognitive and neuroaffective systems. We propose that the CSE model may be useful for understanding the mechanism associating inflammation and psychosis, with applications for drug discovery in that context. PMID:26869217

  20. Esse est percipi: a neurophilosophical model of psychosis.

    Perogamvros, Lampros

    2014-01-01

    Philosophers, psychiatrists and neuroscientists have all expressed interest in and formulated hypotheses on the nature of hallucinations, but no sufficient integration of these models exists to this date. The objective of this article is to present a neurophilosophical model of psychosis linking the neurobiology with the phenomenology of hallucinations and delusions. It is proposed that psychotic hallucinations could be regarded as 'intrusions' of subjective idealism, a condition where reality is mind dependent, into realism, a condition where reality is mind independent. Furthermore, delusions would be an attempt by the person to make sense of these intrusions. This approach is supported by phenomenological evidence of increased self-relatedness in hallucinations and delusions, and by current neurobiological evidence on the role of the reward system, default mode network and corollary discharge circuit in positive symptomatology. This model has clinical, research and therapeutic implications, and also demonstrates how scientific results can be informed and enhanced by philosophical theories and vice versa. PMID:25060543

  1. Cognitive alexithymia is associated with the degree of risk for psychosis.

    Jorien van der Velde

    Full Text Available Alexithymia is a personality construct denoting emotion processing problems. It has been suggested to encompass two dimensions: a cognitive and affective dimension. The cognitive dimension is characterized by difficulties in identifying, verbalizing and analyzing emotions, while the affective dimension reflects the level of emotional arousal and imagination. Alexithymia has been previously proposed as a risk factor for developing psychosis. More specifically, the two alexithymia dimensions might be differentially related to the vulnerability for psychosis. Therefore, we examined the two dimensions of alexithymia, measured with the BVAQ in 94 siblings of patients with schizophrenia, 52 subjects at ultra-high risk (UHR for developing psychosis, 38 patients with schizophrenia and 109 healthy controls. The results revealed that siblings and patients had higher levels of cognitive alexithymia compared to controls. In addition, subjects at UHR for psychosis had even higher levels of cognitive alexithymia compared to the siblings. The levels of affective alexithymia in siblings and patients were equal to controls. However, UHR individuals had significantly lower levels of affective alexithymia (i.e. higher levels of emotional arousal and fantasizing compared to controls. Alexithymia was further related to subclinical levels of negative and depressive symptoms. These findings indicate that alexithymia varies parametrically with the degree of risk for psychosis. More specifically, a type-II alexithymia pattern, with high levels of cognitive alexithymia and normal or low levels of affective alexithymia, might be a vulnerability factor for psychosis.

  2. Social Adversity in the Etiology of Psychosis: A Review of the Evidence.

    Longden, Eleanor; Read, John

    2016-01-01

    Despite increasing evidence for the role of psychosocial factors in the onset and continuance of psychosis, the experiences involved are still largely considered the result of a biogenetic anomaly for which medication is the first-line treatment response. This review summarizes the extensive literature demonstrating that adverse events involving trauma, loss, stress, and disempowerment have a central etiological role in psychosis. Evidence is further presented to show that many neurological changes traditionally considered indicative of a disease process can in fact be accounted for as secondary effects to the physiology of stress or the residual of long-term neuroleptic prescription. Particular emphasis is given to the traumagenic neurodevelopmental model of psychosis, which illustrates how many of the structural and functional cerebral anomalies observed in adult patients with psychosis (including dopamine dysregulation, atrophy, hippocampal damage, and overactivity of the hypothalamic-adrenal-pituitary axis) closely correspond to those in the brains of abused children. Finally, research is discussed that demonstrates how trauma may manifest in characteristic symptoms of psychosis, particularly hallucinations and delusions. It is suggested that if social adversities are of central importance in psychosis, then psychotherapy that addresses the long term sequelae of those adversities should be considered an essential aspect of treatment.

    Cognitive control, a set of functions that develop throughout adolescence, is important in the pathogenesis of psychotic disorders. Whether cognitive control has a role in conferring vulnerability for the development of psychotic illness is still unknown. The aim of this study was to investigate the neural systems supporting cognitive control in individuals deemed to be potentially prodromal for psychotic illness. We recruited 56 participants at clinical high-risk (CHR) for psychosis based on the Structured Interview for Psychosis-Risk Syndromes (SIPS) and 49 healthy controls. Twelve of the CHR participants eventually developed psychosis. We compared functional magnetic resonance imaging (fMRI) BOLD signal during the performance of the Simon task. We tested for differences between CHR individuals and controls in conflict-related functional activity. In the CHR group when compared with controls, we detected smaller conflict-related activations in several cortical areas, including the Dorsolateral Prefrontal Cortex (DLPFC). Furthermore, conflict-related activations in the DLPFC of those CHR individuals who ultimately developed psychosis (CHR converters) were smaller than in non-converters (CHR non-converters). Higher levels of conflict-related activation were associated with better social and role outcome. Risk for psychosis was associated at the neural level with reduced conflict-related brain activity. This neural phenotype appears correlated within the DLPFC with the development of psychosis and with functional outcome. PMID:26354046

  4. Hodological resonance, hodological variance, psychosis and schizophrenia: A hypothetical model

    Paul Brian eLawrie Birkett

    2011-07-01

    Full Text Available Schizophrenia is a disorder with a large number of clinical, neurobiological, and cognitive manifestations, none of which is invariably present. However it appears to be a single nosological entity. This article considers the likely characteristics of a pathology capable of such diverse consequences. It is argued that both deficit and psychotic symptoms can be manifestations of a single pathology. A general model of psychosis is proposed in which the informational sensitivity or responsivity of a network ("hodological resonance" becomes so high that it activates spontaneously, to produce a hallucination, if it is in sensory cortex, or another psychotic symptom if it is elsewhere. It is argued that this can come about because of high levels of modulation such as those assumed present in affective psychosis, or because of high levels of baseline resonance, such as those expected in deafferentation syndromes associated with hallucinations, for example, Charles Bonnet. It is further proposed that schizophrenia results from a process (probably neurodevelopmental causing widespread increases of variance in baseline resonance; consequently some networks possess high baseline resonance and become susceptible to spontaneous activation. Deficit symptoms might result from the presence of networks with increased activation thresholds. This hodological variance model is explored in terms of schizo-affective disorder, transient psychotic symptoms, diathesis-stress models, mechanisms of antipsychotic pharmacotherapy and persistence of genes predisposing to schizophrenia. Predictions and implications of the model are discussed. In particular it suggests a need for more research into psychotic states and for more single case-based studies in schizophrenia.

  5. Biomarker Investigations Related to Pathophysiological Pathways in Schizophrenia and Psychosis

    Gursharan eChana

    2013-06-01

    Full Text Available Post-mortem brain investigations of schizophrenia have generated swathes of data in the last few decades implicating candidate genes and proteins, the relation of these findings to peripheral biomarker indicators and symptomatology remain to be elucidated. While biomarkers for disease do not have to be involved with underlying pathophysiology and may be largely indicative of diagnosis or prognosis, the ideal may be a biomarker that is involved in underlying disease processes and which is therefore more likely to change with progression of the illness as well as potentially being more responsive to treatment. One of the main difficulties in conducting biomarker investigations for major psychiatric disorders is the relative inconsistency in clinical diagnoses between disorders such as bipolar and schizophrenia. This has led some researchers to investigate biomarkers associated with core symptoms of these disorders, such as psychosis. The aim of this review is to evaluate the contribution of post-mortem brain investigations to elucidating the pathophysiology pathways involved in schizophrenia and psychosis, with an emphasis on major neurotransmitter systems that have been implicated. This data will then be compared to functional neuroimaging findings as well as findings from blood based gene expression investigations in schizophrenia in order to highlight the relative overlap in pathological processes between these different modalities used to elucidate pathogenesis of schizophrenia. In addition we will cover some recent and exciting findings demonstrating microRNA dysregulation in both the blood and the brain in patients with schizophrenia. These changes are pertinent to the topic due to their known role in post-transcriptional modification of gene expression with the potential to contribute or underlie gene expression changes observed in schizophrenia. Finally, we will discuss how post-mortem studies may aid future biomarker investigations.

  10. Satisfaction with inpatient treatment for first-episode psychosis among different ethnic groups: A report from the UK AeSOP study.

    Boydell, Jane

    2010-09-17

    BACKGROUND: There is concern about the level of satisfaction with mental healthcare among minority ethnic patients in the UK, particularly as black patients have more compulsory admissions to hospital. AIMS: To determine and compare levels of satisfaction with mental healthcare between patients from different ethnic groups in a three-centre study of first-onset psychosis. METHOD: Data were collected from 216 patients with first-episode psychosis and 101 caregivers from South London, Nottingham and Bristol, using the Acute Services Study Questionnaire (Patient and Relative Version) and measures of sociodemographic variables and insight. RESULTS: No differences were found between ethnic groups in most domains of satisfaction tested individually, including items relating to treatment by ward staff and number of domains rated as satisfactory. However, logistic regression modelling (adjusting for age, gender, social class, diagnostic category and compulsion) showed that black Caribbean patients did not believe that they were receiving the right treatment and were less satisfied with medication than white patients. Black African patients were less satisfied with non-pharmacological treatments than white patients. These findings were not explained by lack of insight or compulsory treatment. CONCLUSIONS: The study found that black patients were less satisfied with specific aspects of treatment, particularly medication, but were equally satisfied with nursing and social care. Understanding the reasons behind this may improve the acceptability of psychiatric care to black minority ethnic groups.

  12. Boredom, dopamine, and the thrill of psychosis: psychiatry in a new key.

    Branković, Saša

    2015-06-01

    Medication non-adherence is a great challenge in the treatment of psychotic disorders. Several factors leading to medication non-adherence in schizophrenia have been identified: drug side-effects, lack of illness insight, negative attitude of the patient and friends/relatives toward medication, stigma of mental illness and taking medication, poor therapeutic alliance, substance abuse, and role of the illness in maintaining the family system. In this work I propose a new vista on the phenomenon of medication non-adherence in psychosis. Rather rule than exception, non-adherence is to be expected in psychosis, it can be considered as a symptom of psychosis similarly as substance craving and use are symptoms of the substance use disorders. Relying on the last refinements of the concepts of boredom, anticipatory anhedonia, intrinsic motivation, and thrill I assume that there is a lure of psychotic episode. In order to escape an extremely unpleasant and distressing experience of boredom and to experience the thrill of psychosis, the patients are prone to quit antipsychotic therapy. The phenomena of boredom and the thrill of psychosis are evident but unexploited for strengthening the therapeutic adherence. Making the lure of psychosis an explicit reason for medication non-adherence would bring to the awareness a personal choice between short-term pleasure of the psychotic thrill and prevention of long-term losses due to a psychotic episode. Neurobiological and psychobiological underpinning of the psychotic thrill has been suggested. An explanation of the pleasure of psychosis and substance use, which overcomes the circular explanation of reward in which dopamine appears as the cause and consequence of reward, has been proposed. The present synthesis can be regarded as a contribution to the field of theoretical psychiatry. It points to a chance for psychiatry to do more for patients' wellbeing and treatment adherence performing in a new key - dealing with boredom and

    Despite the biological plausibility of an association between obstetric mode of delivery and psychosis in later life, studies to date have been inconclusive. We assessed the association between mode of delivery and later onset of psychosis in the offspring. A population-based cohort including data from the Swedish National Registers was used. All singleton live births between 1982 and 1995 were identified (n= 1,345,210) and followed-up to diagnosis at age 16 or later. Mode of delivery was categorized as: unassisted vaginal delivery (VD), assisted VD, elective Caesarean section (CS) (before onset of labor), and emergency CS (after onset of labor). Outcomes included any psychosis; nonaffective psychoses (including schizophrenia only) and affective psychoses (including bipolar disorder only and depression with psychosis only). Cox regression analysis was used reporting partially and fully adjusted hazard ratios (HR) with 95% confidence intervals (CI). Sibling-matched Cox regression was performed to adjust for familial confounding factors. In the fully adjusted analyses, elective CS was significantly associated with any psychosis (HR 1.13, 95% CI 1.03, 1.24). Similar findings were found for nonaffective psychoses (HR 1.13, 95% CI 0.99, 1.29) and affective psychoses (HR 1.17, 95% CI 1.05, 1.31) (χ(2)for heterogeneityP= .69). In the sibling-matched Cox regression, this association disappeared (HR 1.03, 95% CI 0.78, 1.37). No association was found between assisted VD or emergency CS and psychosis. This study found that elective CS is associated with an increase in offspring psychosis. However, the association did not persist in the sibling-matched analysis, implying the association is likely due to familial confounding by unmeasured factors such as genetics or environment.

  14. Ethnic identity, perceptions of disadvantage, and psychosis: findings from the ÆSOP study.

    Reininghaus, Ulrich

    2010-12-01

    Many studies have shown that rates of psychosis are elevated in the Black and minority ethnic (BME) population in the UK. One important, but relatively less researched explanation of these high rates may be social adversity associated with acculturation processes. Strong identification with an ethnic minority group subjected to social disadvantage may exert adverse effects on individuals from BME groups. Using data from a large epidemiological case-control study of first-episode psychosis, we aimed to investigate whether strong ethnic identification is a factor contributing to the excess of psychosis in BME groups compared with the White British, after adjustment for perceptions of disadvantage. All cases with a first episode of psychosis presenting to specialist mental health services within tightly defined catchment areas in London and Nottingham, UK, and geographically matched community controls were included in the study. Data were collected on socio-demographic and clinical characteristics, perceptions of disadvantage, and identification with one\\'s own ethnic group. Analysis was performed on data from 139 cases and 234 controls. There was evidence that, as levels of ethnic identification increased, the odds of psychosis increased in the BME but not in the White British group, independent of potential confounders. However, the association between strong ethnic identity and psychosis in BME individuals was attenuated and non-significant when controlled for perceived disadvantage. Strong identification with an ethnic minority group may be a potential contributory factor of the high rates of psychosis in the BME population, the effects of which may be explained by perceptions of disadvantage.

  17. Identifying persistent negative symptoms in first episode psychosis

    Hovington Cindy L

    2012-12-01

    Full Text Available Abstract Background Although persistent negative symptoms (PNS are known to contribute significantly to poor functional outcome, they remain poorly understood. We examined the heuristic value of various PNS definitions and their respective prevalence in patients with first episode psychosis (FEP. We also contrasted those definitions to the Proxy for the Deficit Syndrome (PDS to identify deficit syndrome (DS in the same FEP cohort. Methods One hundred and fifty-eight FEP patients were separated into PNS and non-PNS groups based on ratings from the Scale for Assessment of Negative Symptoms (SANS. PNS was defined in the following ways: 1 having a score of 3 or greater on at least 1 global subscale of the SANS (PNS_1; 2 having a score of 3 or more on at least 2 global subscales of the SANS (PNS_2; and 3 having a score of 3 or more on a combination of specific SANS subscales and items (PNS_H. For all three definitions, symptoms had to be present for a minimum of six consecutive months. Negative symptoms were measured upon entry to the program and subsequently at 1,2,3,6,9 and 12 months. Functional outcome was quantified at first assessment and month 12. Results PNS prevalence: PNS_1 (27%; PNS_2 (13.2%; PNS_H (13.2%. The prevalence of DS was found to be 3% when applying the PDS. Regardless of the definition being applied, when compared to non-PNS, patients in the PNS group were shown to have significantly worse functioning at month 12. All three PNS definitions showed similar associations with functional outcome at month 12. Conclusion Persistent negative symptoms are present in about 27% of FEP patients with both affective and non-affective psychosis. Although there has previously been doubt as to whether PNS represents a separate subdomain of negative symptoms, the current study suggests that PNS may be more applicable to FEP when compared to DS. Although all three PNS definitions were comparable in predicting functional outcome, we suggest that the

    Background Hallucinations are a core diagnostic criterion for psychotic disorders and have been investigated with regard to its association with childhood trauma in first-episode psychosis samples. Research has largely focused on auditory hallucinations, while specific investigations of visual hallucinations in first-episode psychosis remain scarce. Objectives The aims of this study were to describe the prevalence of visual hallucinations, and to explore the association between visual hallucination and childhood trauma in a first-episode psychosis sample. Methods Subjects were included from TIPS-2, a first episode psychosis study in south Rogaland, Norway. Based on the medical journal descriptions of the Positive and Negative Symptoms Scale (PANSS), a separate score for visual and auditory hallucinations was created (N = 204). Patients were grouped according to hallucination severity (none, mild, and psychotic hallucinations) and multinomial logistic regression was performed to identify factors associated with visual hallucination group. Results Visual hallucinations of a psychotic nature were reported by 26.5% of patients. The experience of childhood interpersonal trauma increased the likelihood of having psychotic visual hallucinations. Conclusion Visual hallucinations are common in first-episode psychosis, and are related to childhood interpersonal trauma. PMID:27144681

  4. Revisiting the Basic Symptom Concept: Towards Translating Risk Symptoms for Psychosis into Neurobiological Targets

    Frauke eSchultze-Lutter

    2016-01-01

    Full Text Available In its initial formulation, the concept of basic symptoms (BSs integrated findings on the early symptomatic course of schizophrenia and first in vivo evidence of accompanying brain aberrations. It argued that the subtle subclinical disturbances in mental processes described as BSs were the most direct self-experienced expression of the underlying neurobiological aberrations of the disease. Other characteristic symptoms of psychosis (e.g., delusions, hallucinations were conceptualized as secondary phenomena, resulting from dysfunctional beliefs and suboptimal coping styles with emerging BSs and/or concomitant stressors. While BSs can occur in many mental disorders, in particular affective disorders, a subset of perceptive and cognitive BSs appear to be specific to psychosis and are currently employed in two alternative risk criteria. However, despite their clinical recognition in the early detection of psychosis, neurobiological research on the aetiopathology of psychosis with neuroimaging methods has only just begun to consider the neural correlate of BSs. This perspective paper reviews the emerging evidence of an association between BSs and aberrant brain activation, connectivity patterns, and metabolism, and outlines promising routes for the use of BSs in aetiopathological research on psychosis.

    2012-01-01

    Over the past years a growing research effort has investigated the relation between cannabis use and schizophrenia at a neurobiological, epidemiological and clinical level. A number of systematic reviews and meta analyses have summarized the available evidence in the field. Conversely the patient's perception of the link between cannabis use and psychosis has been under investigation. Since patient's beliefs and attitudes strongly correlate with adherence to all forms of treatment, we conducted a systematic PUBMED database search for any English and German-language articles published until January 2012 that addressed patient's perception of a cannabis psychosis link. Six studies including psychotic subjects met inclusion criteria yielding a total sample of 97. The vast majority of patients with either schizophrenia or a recent psychosis disagreed with a causal link between cannabis use and their mental illness. We qualitatively reviewed the explanatory models underlying their views, which were multi-factorial, psychological, social, biological, esoteric and irrational factors. Most patient's believed that the temporal sequence of events did not clearly indicate a causal relationship for them. They thus discarded the hypothesis of a causal link between cannabis use and psychosis. Despite the heterogeneity of the included studies, findings are comparable and support the robustness of this review. Limitations and implications for clinicians and psychosis research are discussed.

  6. Bias against disconfirmatory evidence in the 'at-risk mental state' and during psychosis.

    Eisenacher, Sarah; Rausch, Franziska; Mier, Daniela; Fenske, Sabrina; Veckenstedt, Ruth; Englisch, Susanne; Becker, Anna; Andreou, Christina; Moritz, Steffen; Meyer-Lindenberg, Andreas; Kirsch, Peter; Zink, Mathias

    2016-04-30

    Prior studies have confirmed a bias against disconfirmatory evidence (BADE) in schizophrenia which has been associated with delusions. However, its role in the pathogenesis of psychosis is yet unclear. The objective was to investigate BADE for the first time in subjects with an at-risk-mental-state for psychosis (ARMS), patients with a first episode of psychosis without antipsychotic treatment (FEP) and healthy controls (HC). A standard BADE test presenting written scenarios was employed. In addition, psychometric rating scales and a neuropsychological test battery were applied. A three-staged image was revealed. FEP-patients showed a significant BADE compared to the other groups. The performance of ARMS-patients lay in between HC and FEP-patients. A trend towards significance became evident for a bias against confirmatory evidence (BACE) in FEP-patients. Results were not attributable to antipsychotic or other medication or depressive symptoms. Correlations with delusions reached medium effect sizes but failed significance after Bonferroni-corrections. These results provide evidence for aberrations in evidence integration in the pathogenesis of psychosis and contribute to our knowledge of metacognitive functioning which can be used for (meta-)cognitive intervention in psychosis.

    2016-05-30

    The role of protective factors in symptom formation and prognosis in schizophrenia has been shown in many studies, but research in the early phases of psychosis is limited, particularly among the nonclinical subjects. Protective factors associated with the severity of symptoms and clinical outcomes might be meaningful to the establishment of prevention systems and to the development of optimal psychosocial interventions prior to the onset of psychosis. The present study compares self-reported levels of self-esteem, social support and resilience of 32 university students at clinical high risk for psychosis (CHR) and 32 healthy controls in a longitudinal study design. Associations between protective factors with symptoms of psychosis were assessed in the CHR group. Individuals at CHR showed significantly lower self-esteem, social support and resilience compared to healthy controls. In the CHR group, lower social support and lower self-esteem were associated with more severe positive, negative and depressive symptoms. Multiple regression analyses revealed that self-esteem was the only significant determinant for negative, depressive symptoms and global functioning. In addition, we found that subjects who were fully recovered at a 6-month follow-up survey were greater resilient and showed lower depressive symptoms at baseline. The result implied that resilience intervention could be effective on early prevention of the onset of psychosis. Moreover, implications and limitations of this study will be discussed.

    Early intervention for psychosis in Japan has lagged behind that in western countries, but has rapidly begun to attract attention in recent years. As part of a worldwide trend, a multi-dimensional treatment centre for early psychosis consisting of a Youth Clinic, which specialises in young individuals with an at-risk mental state for psychosis, and Il Bosco, a special day-care service for individuals with early psychosis, was initiated at the Toho University Omori Medical Center in Japan in 2007. The treatment centre aims to provide early intervention to prevent the development of full-blown psychosis in patients with an at-risk mental state and intensive rehabilitation to enable first-episode schizophrenia patients to return to the community. We presently provide the same programmes for both groups at Il Bosco. However, different approaches may need to be considered for patients with an at-risk mental state and for those with first-episode schizophrenia. More phase-specific and need-specific services will be indispensable for early psychiatric interventions in the future. PMID:23019284

    2016-09-30

    Suicidality is common among individuals at risk of psychosis. Emerging findings suggest that mental illness stigma contributes to suicidality. However, it is unclear whether stigma variables are associated with suicidality among young people at risk of psychosis. This longitudinal study assessed perceived public stigma and the cognitive appraisal of stigma as a stressor (stigma stress) as predictors of suicidal ideation among individuals at risk of psychosis over the period of one year. One hundred and seventy-two participants between 13 and 35 years of age were included who were at high or ultra-high risk of psychosis or at risk of bipolar disorder. At one-year follow-up, data were available from 73 completers. In multiple logistic regressions an increase of stigma stress (but not of perceived stigma) over one year was significantly associated with suicidal ideation at one-year follow-up, controlling for age, gender, symptoms, comorbid depression and suicidal ideation at baseline. Interventions to reduce public stigma and stigma stress could therefore improve suicide prevention among young people at risk of psychosis. PMID:27419651

Patients were grouped according to hallucination severity (none, mild, and psychotic hallucinations and multinomial logistic regression was performed to identify factors associated with visual hallucination group.Visual hallucinations of a psychotic nature were reported by 26.5% of patients. The experience of childhood interpersonal trauma increased the likelihood of having psychotic visual hallucinations.Visual hallucinations are common in first-episode psychosis, and are related to childhood interpersonal trauma.

    Objective To detect the patterns of cognitive impairment between patients with paranoid schizophrenia and patients with bipolar mania by using the Cambridge Neuropsychological Test Automated Battery (CANTAB) ,and to explore research clues for finding of cognitive endophenotype in patients with paranoid schizophrenia or bipolar mania. Methods Six CANTAB subtests and the seven subtests of the Wechsler Abbreviated Scale of Intelligence (WAIS short form) were administered to 35 patients with paranoid schizophrenia and 33 patients with bipolar mania who were drug naive experiencing an acute episode, as well as 30 healthy controls. Results Patients with paranoid schizophrenia and bipolar mania demonstrated impairments in 13 of the 15 cognitive indicators in CANTAB. After controlling IQ, both patient groups remained as significantly different from normal controls in terms of search strategy(36. 8 ±3.56,37.24 ±4. 21,30. 33 ±6.24) ,between-search errors(40. 86 ± 19.97,40.24 ± 18.92,15.4 ±17.22) on the SWM test,the proportion of hits(0.54 ±0. 18,0.56 ±0.15,0.78 ± 0.17) on the RVIP test,total errors(45.26 ±36.36,46.61 ±33.32,14 ± 11.7) and EDS errors (12.43 ±9.96, 13.18 ±8.98,4.97 ±6.09)on the IED test. Between search error in the SWM test was positively correlation with YMRS scores ( r=0.38, P=0.039) in bipolar patients. Conclusion Both patient groups demonstrated a comparable profile of cognitive impairments during active periods of their condition. The cognitive impairment index may be a discreet cognitive endophenotype overlapping the disorders.%目的 使用剑桥神经心理自动化成套测试(CANTAB)对偏执型精神分裂症与双相躁狂患者认知功能进行比较研究,为寻找认知内表型指标提供线索.方法 采用韦氏智力测试7项简版和CANTAB中的6项分测验对35例未服药、急性期偏执型精神分裂症患者、35例双相躁狂患者和30例正常对照进行测试,通过控制或不控制IQ对认知

  14. Social Stress and Psychosis Risk: Common Neurochemical Substrates?

    Mizrahi, Romina

    2016-02-01

    Environmental risk factors have been implicated in the etiology of psychotic disorders, with growing evidence showing the adverse effects of migration, social marginalization, urbanicity, childhood trauma, social defeat, and other adverse experiences on mental health in vulnerable populations. Collectively, social stress may be one mechanism that could link these environmental risk factors. The exact mechanism(s) by which social stress can affect brain function, and in particular the molecular targets involved in psychosis (such as the dopaminergic (DA) system), is (are) not fully understood. In this review, we will discuss the interplay between social environmental risk factors and molecular changes in the human brain; in particular, we will highlight the impact of social stress on three specific neurochemical systems: DA, neuroinflammation/immune, and endocannabinoid (eCB) signaling. We have chosen the latter two molecular pathways based on emerging evidence linking schizophrenia to altered neuroinflammatory processes and cannabis use. We further identify key developmental periods in which social stress interacts with these pathways, suggesting window(s) of opportunities for novel interventions. Taken together, we suggest that they may have a key role in the pathogenesis and disease progression, possibly provide novel treatment options for schizophrenia, and perhaps even prevent it.

  15. Depression, psychosis, and dementia: impact on the family.

    Ellgring, J H

    1999-01-01

    Similar to the setting of other chronic, debilitating diseases, considerable psychoeducational support of the patient's family and other caregivers represents an often-overlooked component of appropriately thorough care. Nearly three of four persons caring for an individual with PD report psychological stress and anxiety, which are exacerbated by concerns about progression of the disease. Counseling for PD caregivers can be dispensed particularly effectively through individual psychological counseling as well as PD support and community self-help groups that assist caregivers in sharing concerns and promote a sense they are understood by others. Through such measures, which may be delivered effectively by nurse practitioners, PD caregivers can develop effective coping strategies for disease related stressors. Empirical results show the most common stressors are: anxiety, concern about the future, impatience or intolerance, loss of autonomy, sleep disturbances, diminished time and opportunity for recreation and social contact, and anger. These sequelae often ensue when the PD patient evidences depression, advanced dementia, or psychosis, each of which can severely constrain communication. Caregivers often must also contend with two other adverse psychological phenomena: cognitive dissonance surrounding placement of the patient in a nursing home and learned helplessness, which may predispose to depressive states. Other often unmet needs of the "hidden victims" of PD include compromised immune function, social stigmata, and financial difficulties. Respite care may be useful in reducing the stress associated with these and other problems frequently affecting caregivers. PMID:10227606

  16. COMT-by-Sex Interaction Effect on Psychosis Proneness

    Marta de Castro-Catala

    2015-01-01

    Full Text Available Schizotypy phenotypes in the general population share etiopathogenic mechanisms and risk factors with schizophrenia, supporting the notion of psychosis as a continuum ranging from nonclinical to clinical deviance. Catechol-O-methyltransferase (COMT is a candidate susceptibility gene for schizophrenia that is involved in the regulation of dopamine in the prefrontal cortex. Several recent studies have reported a sex difference in the impact of COMT genotype on psychiatric and cognitive phenotypes and personality traits. The present study investigated the association of COMT Val158Met (rs4680 with psychometric positive and negative schizotypy and psychotic experiences in a sample of 808 nonclinical young adults. The main finding was that sex moderates the association of COMT genotype with the negative dimension of both schizotypy and psychotic experiences. Male subjects carrying the Val allele tended to score higher on the negative dimension of both trait and symptom-like measures. The results from the present study are consistent with recent work suggesting an association between negative schizotypy and diminished prefrontal dopamine availability. They support the idea that a biological differentiation underlies the positive and negative schizotypy dimensions. Additionally, these findings contribute to the growing literature on sex-specific effects of COMT on the predisposition to psychiatric disorders and personality traits.

    2016-04-01

    Full Text Available Introduction One of the problems that people with schizophrenia face is the inability to understand and interpret the sensory input from the environment. This report aims to describe the effects of the sensory integration approach on non-paranoid schizophrenia. The treatment involved eight sessions held 3 days a week and lasting 45 minutes each. The patient had a defined Iranians form social relationships schizophrenia evaluated and treatment. Sensory integration therapy in these patients focused on the following elements: vestibular and proprioceptive senses, exercises to improve walking, improving upper extremity coordination and movement, writing activities, cognitive skills, activities of daily living, and family therapy. Case Presentation The subject (A.H. was a 32-year-old male graduate student with no history of previous hospitalization. His diagnosis was schizophrenia. The reason for his hospitalization was that he was angry and violent toward his family. In addition, the patient had limited verbal and nonverbal skills, issues with self-control, and restricted community involvement. The results of the patient’s treatment for schizophrenia was assessed via a questionnaire on social skills. Conclusions After eight sessions, increased awareness of the environment, improved posture and gait pattern, improved motivation and enjoyment, improved patient tolerance, improved appearance and personal hygiene, loss of purposeful behavior, a realistic plan of action every day, improved attention span, improved decision-making skills, and improved community involvement and coping skills were achieved. The environment is rich in sensory stimuli. The integration and processing of each individual senses creates different behavioral responses. The results showed that a sensory integration approach combined with drug therapy is an effective treatment for patients with schizophrenia.

  19. An Introduction to Using the Method of Levels (MOL) Therapy to Work with People Experiencing Psychosis.

    Tai, Sara J

    2016-01-01

    This paper provides a basic introduction to using method of levels (MOL) therapy with people experiencing psychosis. As MOL is a direct application of perceptual control theory (PCT), a brief overview of the three main theoretical principles of this theory--control, conflict, and reorganization will be outlined in relation to understanding psychosis. In particular, how these principles form the basis of problem conceptualisation and determine what an MOL therapist is required to do during therapy will be illustrated. A practical description of MOL will be given, using case examples and short excerpts of therapeutic interactions. Some direct contrasts will also be made with cognitive behaviour therapy for psychosis (CBTp) and psychodynamic approaches (PA) in order to help illustrate the theory and practice of MOL.

  20. Synthetic Cannabinoids-Further Evidence Supporting the Relationship Between Cannabinoids and Psychosis.

    Fattore, Liana

    2016-04-01

    Consumption of synthetic mind-altering compounds, also known as "new psychoactive substances," is increasing globally at an alarming rate. Synthetic cannabinoids (SCs) are among the most commonly used new psychoactive substances. They are usually purchased as marijuana-like drugs, marketed as herbal blends and perceived as risk-free by inexperienced users. Yet, contrary to Δ(9)-tetrahydrocannabinol, SCs may lead to severe health consequences, including anxiety, tachycardia, hallucinations, violent behavior, and psychosis. This review focuses on the latest (2010-2015) evidence of psychotic symptoms induced by ingestion of products containing SCs. Reports suggesting that SCs may either exacerbate previously stable psychotic symptoms (in vulnerable individuals) or trigger new-onset psychosis (in individuals with no previous history of psychosis) are reviewed. Pharmacology and toxicology of these compounds are discussed, with particular reference to their psychoactive effects. PMID:26970364

    OBJECTIVE: Identifying patients at risk of poor outcome at an early stage of illness can aid in treatment planning. This study sought to create a best-fit statistical model of known baseline and early-course risk factors to predict time in psychosis during a ten-year follow-up period after a first...... psychotic episode. METHODS: Between 1997 and 2000, 301 patients with DSM-IV nonorganic, nonaffective first-episode psychosis were recruited consecutively from catchment area-based sectors in Norway and Denmark. Specialized mental health personnel evaluated patients at baseline, three months, and one, two......, five, and ten years (N=186 at ten years). Time in psychosis was defined as time with scores ≥4 on any of the Positive and Negative Syndrome Scale items P1, P3, P5, P6, and G9. Evaluations were retrospective, based on clinical interviews and all available clinical information. During the first two years...

  3. Plasma brain-derived neurotrophic factor levels, learning capacity and cognition in patients with first episode psychosis

    de Azua Sonia Ruiz

    2013-01-01

    Full Text Available Abstract Background Cognitive impairments are seen in first psychotic episode (FEP patients. The neurobiological underpinnings that might underlie these changes remain unknown. The aim of this study is to investigate whether Brain Derived Neurotrophic Factor (BDNF levels are associated with cognitive impairment in FEP patients compared with healthy controls. Methods 45 FEP patients and 45 healthy controls matched by age, gender and educational level were selected from the Basque Country area of Spain. Plasma BDNF levels were assessed in healthy controls and in patients. A battery of cognitive tests was applied to both groups, with the patients being assessed at 6 months after the acute episode and only in those with a clinical response to treatment. Results Plasma BDNF levels were altered in patients compared with the control group. In FEP patients, we observed a positive association between BDNF levels at six months and five cognitive domains (learning ability, immediate and delayed memory, abstract thinking and processing speed which persisted after controlling for medications prescribed, drug use, intelligence quotient (IQ and negative symptoms. In the healthy control group, BDNF levels were not associated with cognitive test scores. Conclusion Our results suggest that BDNF is associated with the cognitive impairment seen after a FEP. Further investigations of the role of this neurotrophin in the symptoms associated with psychosis onset are warranted.

  4. Epigenomic profiling reveals DNA-methylation changes associated with major psychosis.

    Epigenetic misregulation is consistent with various non-Mendelian features of schizophrenia and bipolar disorder. To date, however, few studies have investigated the role of DNA methylation in major psychosis, and none have taken a genome-wide epigenomic approach. In this study we used CpG-island microarrays to identify DNA-methylation changes in the frontal cortex and germline associated with schizophrenia and bipolar disorder. In the frontal cortex we find evidence for psychosis-associated DNA-methylation differences in numerous loci, including several involved in glutamatergic and GABAergic neurotransmission, brain development, and other processes functionally linked to disease etiology. DNA-methylation changes in a significant proportion of these loci correspond to reported changes of steady-state mRNA level associated with psychosis. Gene-ontology analysis highlighted epigenetic disruption to loci involved in mitochondrial function, brain development, and stress response. Methylome network analysis uncovered decreased epigenetic modularity in both the brain and the germline of affected individuals, suggesting that systemic epigenetic dysfunction may be associated with major psychosis. We also report evidence for a strong correlation between DNA methylation in the MEK1 gene promoter region and lifetime antipsychotic use in schizophrenia patients. Finally, we observe that frontal-cortex DNA methylation in the BDNF gene is correlated with genotype at a nearby nonsynonymous SNP that has been previously associated with major psychosis. Our data are consistent with the epigenetic theory of major psychosis and suggest that DNA-methylation changes are important to the etiology of schizophrenia and bipolar disorder. PMID:18319075

  5. Further Evidence That Cannabis Moderates Familial Correlation of Psychosis-Related Experiences.

    Ruud van Winkel

    Full Text Available Familial correlations underlie heritability estimates of psychosis. If gene-environment interactions are important, familial correlation will vary as a function of environmental exposure.Associations between sibling and parental schizotypy (n = 669 pairs, n = 1222 observations, and between sibling schizotypy and patient CAPE psychosis (n = 978 pairs, n = 1723 observations were examined as a function of sibling cannabis use. This design is based on the prediction that in unaffected siblings who are not exposed, vulnerability for psychosis will remain latent, whereas in case of exposure, latent psychosis vulnerability may become expressed, at the level of schizotypal symptoms, causing the phenotypic correlation between relatives to become "visible" under the influence of cannabis.Siblings exposed to recent cannabis use resembled their patient-relative more closely in terms of positive schizotypy (urinalysis(+:B = 0.30, P<.001; urinalysis(-:B = 0.10, p<0.001; p-interaction = 0.0135. Similarly, the familial correlation in positive schizotypy between parent and sibling was significantly greater in siblings recently exposed to cannabis (urinalysis(+:B = 0.78, P<.001; urinalysis(-:B = 0.43, p<0.001; p interaction = 0.0017. Results were comparable when using lifetime cannabis frequency of use as exposure instead of recent use. Parental schizotypy did not predict cannabis use in the healthy sibling, nor in the patient. Similarly, parental cannabis use was not associated with level of schizotypy in the sibling, nor with psychotic symptoms in the patient, making gene-environment correlation unlikely.Familial correlation of psychosis-related experiences varies considerably as a function of exposure to cannabis, confirming the importance of gene-cannabis interaction in shifts of expression of psychosis-related experiences.

    Utilizing postmortem data (Breese et al. [2000] Neuropsychopharmacology 23:351-364), we hypothesized that the densities of high-affinity neuronal α4β2 nicotinic acetylcholine receptors (nAChRs) in the brain exist in a continuum from highest to lowest as follows: smokers without schizophrenia > smokers with schizophrenia > nonsmokers without schizophrenia > nonsmokers with schizophrenia. Application of the Kruskal-Wallis Test (Statacorp, 2003) to the postmortem data (Breese et al. [2000] Neuropsychopharmacology 23:351-364) confirmed the hypothesized order in the cortex and the hippocampus and attained significance in the caudate and the thalamus. Positron emission tomography (PET) was performed for 60 min at 6 h after the intravenous administration of 444 megabequerels [MBq] (12 mCi) 2-[¹⁸F]fluoro-3-(2(S)-azetidinylmethoxy)pyridine (2-[¹⁸F]FA), a radiotracer for high-affinity neuronal α4β2 nAChRs, as a bolus plus continuous infusion to 10 adults (seven men and three women) (six smokers including five with paranoid schizophrenia and four nonsmokers) ranging in age from 22 to 56 years (mean 40.1, standard deviation 13.6). The thalamic nondisplaceable binding potential (BP(ND) ) was 1.32 ± 0.19 (mean ± standard deviation) for healthy control nonsmokers; 0.50 ± 0.19 for smokers with paranoid schizophrenia; and 0.51 for the single smoker without paranoid schizophrenia. The thalamic BP(ND) s of nonsmokers were significantly higher than those of smokers who smoked cigarettes a few hours before the scans (P = 0.0105) (StataCorp, 2003), which was likely due to occupancy of nAChRs by inhaled nicotine in smokers. Further research is needed to rule out the effects of confounding variables. PMID:22169936

It is necessary for us to analyze the criminal suspects' personality, which may show us the criminal's psychology mechanism and can reduce the potential with personality defect change to the offender. Qiu Xinghua belongs to the typical paranoid personality which mainly results from his experience: early loss of love made him emotional dysplasia; lack of self-reflection leads to negative mental deposition; and vanity of self-esteem makes him sensitive and jealous, which finally results in his paranoid delusions. The article here tries to put forward some suggestions to prevent paranoid personality, improve people's psychological health, and reduce similar social tragedy.

    Fenton, Kelly; Larkin, Michael; Boden, Zoë V R; Thompson, Jessica; Hickman, Gareth; Newton, Elizabeth

    2014-11-01

    Early Intervention in Psychosis services aim to keep young people out of hospital, but this is not always possible. This research used in-depth interviews to explore the experience of hospitalisation amongst young people with psychosis. Findings describe fear and confusion at admission, conflicting experiences of the inpatient unit as both safe and containing, and unsafe and chaotic, and the difficult process of maintaining identity in light of the admission. We discuss the need to move from construing psychiatric hospitals as places for 'passive seclusion', to developing more permeable and welcoming environments that can play an active role in recovery.

  16. Psychiatric Disease and Post-Acute Traumatic Brain Injury.

    Zgaljardic, Dennis J; Seale, Gary S; Schaefer, Lynn A; Temple, Richard O; Foreman, Jack; Elliott, Timothy R

    2015-12-01

    Psychiatric disorders are common following traumatic brain injury (TBI) and can include depression, anxiety, and psychosis, as well as other maladaptive behaviors and personality changes. The epidemiologic data of psychiatric disorders post-TBI vary widely, although the incidence and prevalence rates typically are higher than in the general population. Although the experience of psychiatric symptoms may be temporary and may resolve in the acute period, many patients with TBI can experience psychopathology that is persistent or that develops in the post-acute period. Long-term psychiatric disorder, along with cognitive and physical sequelae and greater risk for substance use disorders, can pose a number of life-long challenges for patients and their caregivers, as they can interfere with participation in rehabilitation as well as limit functional independence in the community. The current review of the literature considers the common psychiatric problems affecting individuals with TBI in the post-acute period, including personality changes, psychosis, executive dysfunction, depression, anxiety, and substance misuse. Although treatment considerations (pharmacological and nonpharmacological) are referred to, an extensive description of such protocols is beyond the scope of the current review. The impact of persistent psychiatric symptoms on perceived caregiver burden and distress is also discussed. PMID:25629222

  17. Internet Addiction, Hikikomori Syndrome, and the Prodromal Phase of Psychosis

    Stip, Emmanuel; Thibault, Alexis; Beauchamp-Chatel, Alexis; Kisely, Steve

    2016-01-01

    Computers, video games, and technological devices are part of young people’s everyday lives. Hikikomori is a Japanese word describing a condition that mainly affects adolescents or young adults who live isolated from the world, cloistered within their parents’ homes, locked in their bedrooms for days, months, or even years on end, and refusing to communicate even with their family. These patients use the Internet profusely, and only venture out to deal with their most imperative bodily needs. Although first described in Japan, cases have been described from around the world. This is the first published report from Canada. The disorder shares characteristics with prodromal psychosis, negative symptoms of schizophrenia, or Internet addiction, which are common differential or comorbid diagnoses. However, certain cases are not accompanied by a mental disorder. Psychotherapy is the treatment of choice although many cases are reluctant to present. The exact place of hikikomori in psychiatric nosology has yet to be determined. We searched Medline up to 12th May, 2015 supplemented by a hand search of the bibliographies of all retrieved articles. We used the following search terms: Hikikomori OR (prolonged AND social AND withdrawal). We found 97 potential papers. Of these 42 were in Japanese, and 1 in Korean. However, many of these were cited by subsequent English language papers that were included in the review. Following scrutiny of the titles and abstracts, 29 were judged to be relevant. Further research is needed to distinguish between primary and secondary hikikomori and establish whether this is a new diagnostic entity, or particular cultural or societal manifestations of established diagnoses.

  18. Computerized tomography findings on schizophrenia and atypical psychosis

    The brain CTs of 54 endogenous psychotics (27 males, 27 females) who were less than 40 years of age and were first adimitted in Aichi Medical University from 1982 to 1986, and 20 controls (10 males, 10 females) were examined. Using Mitsuda's classification, we devided all the cases into 29 schizophrenics (18 males, 11 females) and 25 atypical psychotics (9 males, 16 females). In order to investigate the differences of CT findings between the two patient groups, the 3rd ventricle index (the ratio of 3rd ventricle width to the internal diameter of the skull), Evans'ratio, lateral ventricle brain ratio (VBR), Sylvian fissure to brain ratio, 4th ventricle to cerebellum ratio were determined. Schizophrenics had larger 3rd and lateral ventricles as well as Sylvian fissures when compared to controls, but atypical psychotics had not. Moreover, schizophrenics had larger 3rd and lateral ventricle than atypical psychotics. But in widths of Sylvian fissures there was no statistical significant difference between the two groups. Ventricle enlargements of schizophrenics did not correlate with duration of illness as well as age, and were not results of prior psychiatric treatment such as medication and EST. Therefore the following is suggested that, this abnormal CT findings predate the onset of schizophrenic psychoses. In atypical psychotics the changes of Sylvian fissures correlated with duration of illness, but not with age. Such observations may possibly suggest that recurrence of the illness might finally attain irreversible changes even in atypical psychotics.

    Full Text Available Computers, video games and technological devices are part of young people's everyday lives. Hikikomori, a Japanese word describing a condition that mainly affects adolescents or young adults who live isolated from the world, cloistered within their parents’ homes, locked in their bedrooms for days, months or even years on end, refusing to communicate even with their family, using internet profusely and only venturing out to deal with their most imperative bodily needs. Although first described in Japan, cases have been described from around the world, this is the first published report from Canada. The disorder sharescharacteristics with prodromal psychosis, negative symptoms of schizophrenia or internet addiction, which are common differential or comorbid diagnoses. Certain cases, however, are not accompanied by a mental disorder. Psychotherapy is the treatment of choice although many cases are reluctant to present. The exact place of hikikomori in psychiatric nosology has yet to be determined. We searched Medline up to 12th May, 2015 supplemented by a hand search of the bibliographies of all retrieved articles. We used the following search terms: Hikikomori OR (prolonged AND social AND withdrawal. We found 97 potential papers. Of these 42, were in Japanese, and one in Korean. However, many of these were cited by subsequent English-language papers that were included in the review. Following scrutiny of the titles and abstracts, 29 were judged to be relevant. Further research is needed to distinguish between primary and secondary hikikomori and establish whether this is a new diagnostic entity, or particular cultural or societal manifestations of established diagnoses.
