    Dementia is foremost a clinical diagnosis. However, in diagnosing dementia, it is advocated to perform at least one neuroimaging study. This has two purposes: to rule out potential reversible dementia (PRD), and to help determine the dementia subtype. Our first goal was to establish if MRI combined with visual rating scales changes the clinical diagnosis. The second goal was to demonstrate if MRI contributes to a geriatrician's confidence in the diagnosis. The dementia subtype was determined prior to and after MRI. Scoring scales used were: global cortical atrophy (GCA), medial temporal atrophy (MTA), and white matter hyperintensity measured according to the Fazekas scale. The confidence level of the geriatrician was determined using a visual analogue scale. One hundred and thirty-five patients were included. After MRI, the diagnosis changed in 23.7 % (CI 17.0 %-31.1 %) of patients. Change was due to vascular aetiology in 13.3 % of patients. PRD was found in 2.2 % of all patients. The confidence level in the diagnosis increased significantly after MRI (p = 0.001). MRI, combined with visual rating scales, has a significant impact on dementia subtype diagnosis and on a geriatrician's confidence in the final diagnosis. (orig.)

    Full Text Available Background: The Clinical Dementia Rating (CDR scale is widely used to assess cognitive impairment in Alzheimer's disease. It requires collateral information from a reliable informant who is not available in many instances. We adapted the original CDR scale for use with elderly subjects without an informant (CDR-NI and evaluated its reliability and validity for assessing mild cognitive impairment (MCI and dementia among community-dwelling elderly subjects. Method: At two consecutive visits 1 week apart, nurses trained in CDR assessment interviewed, observed and rated cognitive and functional performance according to a protocol in 90 elderly subjects with suboptimal cognitive performance [Mini-Mental State Examination (MMSE Results: The CDR-NI scores (0, 0.5, 1 showed good internal consistency (Crohnbach's a 0.83-0.84, inter-rater reliability (κ 0.77-1.00 for six domains and 0.95 for global rating and test-retest reliability (κ 0.75-1.00 for six domains and 0.80 for global rating, good agreement (κ 0.79 with the clinical assessment status of MCI (n = 37 and dementia (n = 4 and significant differences in the mean scores for MMSE, MOCA and Instrumental Activities of Daily Living (ANOVA global p Conclusion: Owing to the protocol of the interviews, assessments and structured observations gathered during the two visits, CDR-NI provides valid and reliable assessment of MCI and dementia in community-living elderly subjects without an informant.

    Decline of the cognitive functions necessary for activities of daily living results in a spectrum ranging from benign forgetfulness and minimal cognitive impairment to dementia. The latter is characterized by personality and behavioral changes. Alzheimer's disease is the most frequent cause of dementia affecting almost one of two people older than 80 years. Lewy body and cerebrovascular disease are also frequent causes of cognitive decline. Recent studies have revealed genetic aspects of Alzheimer's disease and the role of certain enzymes in the pathophysiology of fibrillary amyloid deposition. The aim in cognitive disease is an early diagnosis to initiate therapy and adapting measures in the patient's daily routines. The diagnosis is basically clinical with neuroimaging and neuropsychological tests' support. The EEG, SPECT, LP and other studies are only useful in a few specific scenarios. At present, a few promising therapies are being evaluated. Family support is of vital importance.

    Full Text Available Dementia is characterized by progressive decline in an alert individual, leading to loss of independence in day-to-day functioning. It is a generic term for a condition that has various causes and hence myriad clinical presentations. It has to be distinguished from age-related cognitive decline, depression and delirium all of which are common in the elderly population. Detailed history and mental status examination are necessary to identify dementia, fit it into one of the various bedside classifications and pursue the differential diagnosis. This teaching review summarizes current information on definition, differential diagnosis and classification of dementia and presents a brief elaboration of bedside cognitive testing pertaining to dementia. A bird′s eye view of the profiles of various dementia subtypes is also provided so that after reading this article the reader will able to recognize dementia, conduct clinical examination to identify the characteristic cognitive profile and formulate the differential diagnosis with confidence.

    In this review, we present an overview of clinical studies that addressed the relationship between depression and dementia or cognitive decline. Cross-sectional studies and meta-analyses have repeatedly shown an association between late-life depression (LLD) and dementia, particularly Alzheimer's disease (AD) and vascular dementia; however, the findings of cohort studies have been inconsistent. Furthermore, studies on the association between depression with a younger age of onset and dementia have yielded inconsistent results. Regarding cognitive decline associated with LLD, several studies have reported an association between LLD and mild cognitive impairment, suggesting that depression itself can cause persistent cognitive impairment. Other studies have compared the cognitive profile between LLD and depression with a younger age of onset, but their results have been inconclusive, especially regarding the association between memory impairment and the age of onset of depression. LLD is associated with vascular change and white matter degeneration of the brain, as shown by magnetic resonance imaging (MRI). Recently, several studies reported an association between gray matter change and LLD. Studies currently in progress employ functional brain imaging methods such as single-photon emission computed tomography, functional MRI, and positron emission tomography. Clinically, it is important to understand how subtypes of depression can be defined in terms of risk of developing dementia, and to devise effective treatments. One paper explored the possibility of detecting depression associated with AD by measuring the blood Aβ40/Aβ42 levels, and other studies have suggested that symptoms of apathy and loss of interest are associated with conversion of depression to AD. Unfortunately, current antidepressants may have limited efficacy on depression with dementia; therefore, further investigation for devising methods of predicting conversion of depression to dementia and

    Full Text Available Jacob HG Grand¹, Sienna Caspar², Stuart WS MacDonald11Department of Psychology, University of Victoria, Victoria, BC, Canada; 2Interdisciplinary Graduate Studies, University of British Columbia, Vancouver, BC, CanadaAbstract: Dementia is a clinical syndrome of widespread progressive deterioration of cognitive abilities and normal daily functioning. These cognitive and behavioral impairments pose considerable challenges to individuals with dementia, along with their family members and caregivers. Four primary dementia classifications have been defined according to clinical and research criteria: 1 Alzheimer’s disease; 2 vascular dementias; 3 frontotemporal dementias; and 4 dementia with Lewy bodies/Parkinson’s disease dementia. The cumulative efforts of multidisciplinary healthcare teams have advanced our understanding of dementia beyond basic descriptions, towards a more complete elucidation of risk factors, clinical symptoms, and neuropathological correlates. The characterization of disease subtypes has facilitated targeted management strategies, advanced treatments, and symptomatic care for individuals affected by dementia. This review briefly summarizes the current state of knowledge and directions of dementia research and clinical practice. We provide a description of the risk factors, clinical presentation, and differential diagnosis of dementia. A summary of multidisciplinary team approaches to dementia care is outlined, including management strategies for the treatment of cognitive impairments, functional deficits, and behavioral and psychological symptoms of dementia. The needs of individuals with dementia are extensive, often requiring care beyond traditional bounds of medical practice, including pharmacologic and non-pharmacologic management interventions. Finally, advanced research on the early prodromal phase of dementia is reviewed, with a focus on change-point models, trajectories of cognitive change, and threshold models of

  11. Using dementia rating scales in the diagnosis of Alzheimer's disease

    2006-01-01

    Objective: To study the significance of dementia rating scales in the diagnosis of Alzheimer' s disease (AD).Methods: Probable AD patients(118 cases) diagnosed according to NINCDS-ADRDA criteria and the normal controls(100 cases) were examined with a battery of neuropsychological tests and the dementia severity of AD patients was determined with clinical dementia rating(CDR). Changed neuropsychological characteristics of different AD dementia severities were analyzed. The discriminant analysis and ROC curve analysis were performed to analyze the specificity, the sensitivity, and the general accuracy of various dementia rating scales in the diagnosis of AD, and the area under the ROC curve. Results: The total cognition function in mild (CDR = 1), moderate(CDR = 2) and severe stages(CDR=3) of AD had an obvious trend of continuous decline, with the MMSE values 17.44 ± 2.64, 13.90 ± 4.32, and5.50± 3.90 respectively. The trend of decline of the verbal fluency function in AD was same as that of total cognition function. The visuospatial function was reduced in early stage of AD (CDR = 1 ) and completely lost in moderate and severe AD. Delay memory function began to show decline in the early stage of AD, and the decline turned apparent in moderate and severe AD. Immediate memory function showed unchanged in early stage of AD, while showed decline in moderate AD, and the decline became very quick in severe AD. The impairment of daily living ability and social activity function developed with the severity degree of AD. But the decline of social activity function was very quick in moderate stage of AD. In general, the leading scale to diagnose AD was FOM, followed by RVR, POD, MMSE, BD,ADL and DS. When MMSE was combined with one or more of FOM, RVR, BD, DS, the general accuracy in distinguishing AD from the normal controls was improved. Conclusion: Neuropsychological test is useful in the diagnosis of AD, especially in the early stage. The validity is improved when

    Objective This study aimed to develop a pathway to bring together current UK legislation, good clinical practice and appropriate management strategies that could be applied across a range of healthcare settings. Methods The pathway was constructed by a multidisciplinary clinical team based in a busy Memory Assessment Service. A process of successive iteration was used to develop the pathway, with input and refinement provided via survey and small group meetings with individuals from a wide range of regional clinical networks and diverse clinical backgrounds as well as discussion with mobility centres and Forum of Mobility Centres, UK. Results We present a succinct clinical pathway for patients with dementia, which provides a decision-making framework for how health professionals across a range of disciplines deal with patients with dementia who drive. Conclusions By integrating the latest guidance from diverse roles within older people's health services and key experts in the field, the resulting pathway reflects up-to-date policy and encompasses differing perspectives and good practice. It is potentially a generalisable pathway that can be easily adaptable for use internationally, by replacing UK legislation for local regulations. A limitation of this pathway is that it does not address the concern of mild cognitive impairment and how this condition relates to driving safety. © 2014 The Authors.

    Every day, patients with dementia, their families, and their physicians face the enormous challenges of this pervasive life-changing condition. Seeking help, often grasping at straws, victims, and their care providers are confronted with misinformation and myths when they search the internet or other sources. When Persons with Dementia (PWD) and their caregivers believe and/or act on false information, proper treatment may be delayed, and ultimately damage can be done. In this paper, we review commonly misunderstood issues encountered in caring for PWD. Our goal is to equip Primary Care Practitioners (PCPs) with accurate information to share with patients and families, to improve the outcomes of PWD to the greatest extent possible. While there are innumerable myths about dementia and its causes and treatments, we are going to focus on the most common false claims or misunderstandings which we hear in our Internal Medicine practice at Marshall Health. We offer suggestions for busy practitioners approaching some of the more common issues with patients and families in a clinic setting.

    Full Text Available The endocannabinoid system has been shown to be associated with neurodegenerative diseases and dementia. We review the preclinical and clinical data on cannabinoids and four neurodegenerative diseases: Alzheimer’s disease (AD, Huntington’s disease (HD, Parkinson’s disease (PD and vascular dementia (VD. Numerous studies have demonstrated an involvement of the cannabinoid system in neurotransmission, neuropathology and neurobiology of dementias. In addition, several candidate compounds have demonstrated efficacy in vitro. However, some of the substances produced inconclusive results in vivo. Therefore, only few trials have aimed to replicate the effects seen in animal studies in patients. Indeed, the literature on cannabinoid administration in patients is scarce. While preclinical findings suggest causal treatment strategies involving cannabinoids, clinical trials have only assessed the suitability of cannabinoid receptor agonists, antagonists and cannabidiol for the symptomatic treatment of dementia. Further research is needed, including in vivo models of dementia and human studies.

    The importance of evaluating effort in neuropsychological assessments has been widely acknowledged, but measuring effort in the context of dementia remains challenging due to the impact of dementia severity on effort measure scores. Two embedded measures have been developed for the repeatable battery for the assessment of neuropsychological status (RBANS; Randolph, C., Tierney, M. C., Mohr, E., & Chase, T. N. (1998). The repeatable battery for the assessment of neuropsychological status (RBANS): Preliminary clinical validity. Journal of Clinical and Experimental Neuropsychology, 20 (3), 310-319): the Effort Index (EI; Silverberg, N. D., Wertheimer, J. C., & Fichtenberg, N. L. (2007). An effort index for the repeatable battery for the assessment of neuropsychological status (RBANS). Clinical Neuropsychologist, 21 (5), 841-854) and the Effort Scale (ES; Novitski, J., Steele, S., Karantzoulis, S., & Randolph, C. (2012). The repeatable battery for the assessment of neuropsychological status effort scale. Archives of Clinical Neuropsychology, 27 (2), 190-195). We explored failure rates on these effort measures in a non-litigating mixed dementia sample (N = 145). Failure rate on the EI was high (48%) and associated with dementia severity. In contrast, failure on the ES was 14% but differed based on type of dementia. ES failure was low (4%) when dementia was due to Alzheimer disease (AD), but high (31%) for non-AD dementias. These data raise concerns about use of the RBANS embedded effort measures in dementia evaluations.

    Full Text Available An enhanced life expectancy in developed countries has been accompanied by an increased number of people suffering from age-associated dementia. Senile dementia is a syndrome due to disease of the brain, usually of a chronic or progressive nature, in which there is disturbance of multiple higher cortical functions, without any impairment in consciousness. Prevalence rates for senile dementia increase essentially with advancing age. The prevalence rate rises to 54.8% in individuals above 95 years of age. So far, efforts to find a cure for Alzheimer Disease (AD have been disappointing, and the drugs currently available to treat the disease address only its symptoms and with limited effectiveness. Present study was design to see the efficacy of Saraswata ghrita along with Shirobasti on Senile dementia. A total number of 34 patient of Senile dementia were recruited by using ICD-10 criteria of Dementia and MMSE scores and randomly divided in to two groups. Alzheimer’s disease assessment scale (cognitive subscale has been used to evaluate the clinical condition of the patients of Senile dementia. After completion of treatment Saraswata ghrita along with Shirobasti shows statistically significant results on clinical and neuro-cognitive parameters.

    Full Text Available Abstract Dementia with Parkinson's disease represents a controversial issue in the complex group of alpha-synucleinopathies. The author acknowledges the concept of a "continuum" between Parkinson disease's (PD, Lewy body dementia (LBD, and dementia in Parkinson's disease (PDD. However, the practicing neurologist needs to identify the phenotypic signs of each dementia. The treatment and prognosis are different in spite of the overlaps between them. The main aim of this review was to characterize the clinical diagnoses of dementia associated with Parkinson's disease (PDD. Secondarily, the review discussed some epidemiological and neuropsychological issues. Selection of articles was not systematic and reflects the author's opinion, where the main text selected was the recommendations from the Movement Disorder Society Task Force for PDD diagnosis. The Pub Med, OVID, and Proquest data bases were used for the search.

    Alzheimer's disease pathology frequently coexists with Lewy body disease at autopsy in patients with probable dementia with Lewy bodies. More than half of patients with probable dementia with Lewy bodies have high amyloid-β deposition as measured with (11)C-Pittsburgh compound B binding on positron emission tomography. Biomarkers of amyloid-β deposition precede neurodegeneration on magnetic resonance imaging during the progression of Alzheimer's disease, but little is known about how amyloid-β deposition relates to longitudinal progression of atrophy in patients with probable dementia with Lewy bodies. We investigated the associations between baseline (11)C-Pittsburgh compound B binding on positron emission tomography and the longitudinal rates of grey matter atrophy in a cohort of clinically diagnosed patients with dementia with Lewy bodies (n = 20), who were consecutively recruited to the Mayo Clinic Alzheimer's Disease Research Centre. All patients underwent (11)C-Pittsburgh compound B positron emission tomography and magnetic resonance imaging examinations at baseline. Follow-up magnetic resonance imaging was performed after a mean (standard deviation) interval of 2.5 (1.1) years. Regional grey matter loss was determined on three-dimensional T1-weighted magnetic resonance imaging with the tensor-based morphometry-symmetric normalization technique. Linear regression was performed between baseline (11)C-Pittsburgh compound B standard unit value ratio and longitudinal change in regional grey matter volumes from an in-house modified atlas. We identified significant associations between greater baseline (11)C-Pittsburgh compound B standard unit value ratio and greater grey matter loss over time in the posterior cingulate gyrus, lateral and medial temporal lobe, and occipital lobe as well as caudate and putamen nuclei, after adjusting for age (P < 0.05). Greater baseline (11)C-Pittsburgh compound B standard unit value ratio was also associated with greater

METHODS: Procedures provided for diagnosis included physical and neurological examination, laboratory tests, neuroimaging and DSM-IV. The functional capacity and level of cognitive deficit were assessed by Pfeffer Functional Activities Questionnaire (Pfeffer-FAQ and Mini-Mental State Examination (MMSE, respectively. RESULTS: Eighty patients met the criteria for dementia. The mean age was 63.48 (± 16.85 years old, the schooling was 3.30 (± 3.59 years old, the MMSE was 13.89 (± 7.79 and Pfeffer 17.73 (± 9.76. The Vascular Dementia (VD; 17.5% was the most frequent cause of dementia, followed by Lewy body dementia (LBD and Alzheimer's disease (AD (12.25%. CONCLUSION: Considering entire sample and only the elderly over 60 years, VD, AD and LBD are the most common subtypes observed at both groups. Further epidemiological studies are necessary to confirm such rates, which may have a considerable impact on the organization and planning of healthcare services in our country.

    63 patients with senile vascular dementia were randomly divided into the treatment group (treated by acupuncture) and the control group (treated with piracetam). The authors observed the changes in the score of Hasegawa's dementia scale (HDS), p300, rheoencephalogram, topographic EEG, superoxide dismutase (SOD) activity in erythrocytes, and lipid peroxide (LPO) level in plasma before and after treatment. The statistical data showed that the total effective rate in the treatment group (80.6%) was significantly higher than that in the control group (25%), and the differences in the observed indexes before and after treatment were significant (P0.05), indicating that the acupuncture treatment was superior in immediate therapeutic effect on senile vascular dementia to drug treatment.

    Dementia is common in the elderly, but there are currently no effective therapies available to prevent or treat this syndrome. In the last decade, polyphenols (particularly curcumin, resveratrol and tea catechins) have been under very close scrutiny as potential therapeutic agents for neurodegenerative diseases, diabetes, inflammatory diseases and aging. Data were collected from Web of Science (ISI Web of Knowledge), Pubmed and Medline (from 2000 to 2015), by searching for the keywords "dementia" AND "curcumin", "resveratrol", "EGCG", "tea catechins". The same keywords were used to investigate the current state of clinical trials recorded in the NIH clinicaltrials.gov registry. Starting from the intrinsic properties of the compounds, we explain their specific action in patients with AD and the most common types of dementia. The pharmacological actions of curcumin, resveratrol and tea catechins have mainly been attributed to their antioxidant activity, interaction with cell signaling pathways, anti-inflammatory effect, chelation of metal ions, and neuroprotection. Evidence from in vitro and in vivo studies on polyphenols have demonstrated that they may play an integral role in preventing and treating diseases associated with neurodegeneration. Furthermore, we critically analyze the clinical trials that we found, which investigate the real pharmacological actions and the possible side effects of these compounds. This review highlights the potential role of polyphenols in the prevention/treatment of dementia and describes the current limitations of research in this field.

    Thais Bento Lima-Silva

    Full Text Available ABSTRACT Background: Staging scales for dementia have been devised for grading Alzheimer's disease (AD but do not include the specific symptoms of frontotemporal lobar degeneration (FTLD. Objective: To translate and adapt the Frontotemporal Dementia Rating Scale (FTD-FRS to Brazilian Portuguese. Methods: The cross-cultural adaptation process consisted of the following steps: translation, back-translation (prepared by independent translators, discussion with specialists, and development of a final version after minor adjustments. A pilot application was carried out with 12 patients diagnosed with bvFTD and 11 with AD, matched for disease severity (CDR=1.0. The evaluation protocol included: Addenbrooke's Cognitive Examination-Revised (ACE-R, Mini-Mental State Examination (MMSE, Executive Interview (EXIT-25, Neuropsychiatric Inventory (NPI, Frontotemporal Dementia Rating Scale (FTD-FRS and Clinical Dementia Rating scale (CDR. Results: The Brazilian version of the FTD-FRS seemed appropriate for use in this country. Preliminary results revealed greater levels of disability in bvFTD than in AD patients (bvFTD: 25% mild, 50% moderate and 25% severe; AD: 36.36% mild, 63.64% moderate. It appears that the CDR underrates disease severity in bvFTD since a relevant proportion of patients rated as having mild dementia (CDR=1.0 in fact had moderate or severe levels of disability according to the FTD-FRS. Conclusion: The Brazilian version of the FTD-FRS seems suitable to aid staging and determining disease progression.

    In the prospect of improved disease management and future clinical trials in Frontotemporal Dementia, it is desirable to share common diagnostic procedures. To this aim, the Italian FTD Network, under the aegis of the Italian Neurological Society for Dementia, has been established. Currently, 85 Italian Centers involved in dementia care are part of the network. Each Center completed a questionnaire on the local clinical procedures, focused on (1) clinical assessment, (2) use of neuroimaging and genetics; (3) support for patients and caregivers; (4) an opinion about the prevalence of FTD. The analyses of the results documented a comprehensive clinical and instrumental approach to FTD patients and their caregivers in Italy, with about 1,000 newly diagnosed cases per year and 2,500 patients currently followed by the participating Centers. In analogy to other European FTD consortia, future aims will be devoted to collect data on epidemiology of FTD and its subtypes and to provide harmonization of procedures among Centers.

    Full Text Available Caring for a demented family member has been associated with burden. Studies concerning health self-perception of family caregivers are still scarce. OBJECTIVE: To investigate caregivers perceived health and to look into relationships with patients and caregivers' sociodemographic and clinical data. METHOD: Dyads of dementia outpatients and family caregivers (n=137 were assessed with Mini Mental State Examination, Functional Activities Questionnaire, Neuropsychiatric Inventory and Clinical Dementia Rating. Caregivers answered Sociodemographic Questionnaire, Beck Depression and Anxiety Inventories, Zarit Burden Interview and Maslach Burnout Inventory. RESULTS: Caregivers poor perceived health was associated with emotional exhaustion, burden, depression and anxiety. Logistic regression analyses revealed caregivers' age, anxiety and physical problem as the main predictors of health self-perception. CONCLUSION: Aged family caregivers with anxiety who also report physical problem characterize a group at risk for poor self-perceived health. Evaluation of health self-perception may be useful for designing interventions to improve anxiety and physical health.

    University students in speech-language pathology and nursing were involved in a community service learning project with residents of a long-term care facility who had dementia. Nursing students were asked to interact and converse with residents to the best of their ability (control group, n = 28). Speech-language pathology students were instructed to design a personalized, multi-modality "connection kit" for residents based on the tenets of cognitive linguistic stimulation and facilitative styles of interaction, which were included within course content (experimental group, n = 25). Post-project surveys were administered in an attempt to answer the following research question: Do students perceive benefits from participating in a service learning project involving long-term care residents with dementia? Results revealed that the experimental/trained group of speech-language pathology students reported greater academic and clinical benefits compared to the control group of nursing students. Overall implications were that students benefited from a service learning project, especially when explicit instruction was provided.

  12. Cognitive reserve in granulin-related frontotemporal dementia: from preclinical to clinical stages.

    Directory of Open Access Journals (Sweden)

    Enrico Premi

    Full Text Available OBJECTIVE: Consistent with the cognitive reserve hypothesis, higher education and occupation attainments may help persons with neurodegenerative dementias to better withstand neuropathology before developing cognitive impairment. We tested here the cognitive reserve hypothesis in patients with frontotemporal dementia (FTD, with or without pathogenetic granulin mutations (GRN+ and GRN-, and in presymptomatic GRN mutation carriers (aGRN+. METHODS: Education and occupation attainments were assessed and combined to define Reserve Index (RI in 32 FTD patients, i.e. 12 GRN+ and 20 GRN-, and in 17 aGRN+. Changes in functional connectivity were estimated by resting state fMRI, focusing on the salience network (SN, executive network (EN and bilateral frontoparietal networks (FPNs. Cognitive status was measured by FTD-modified Clinical Dementia Rating Scale. RESULTS: In FTD patients higher level of premorbid cognitive reserve was associated with reduced connectivity within the SN and the EN. EN was more involved in FTD patients without GRN mutations, while SN was more affected in GRN pathology. In aGRN+, cognitive reserve was associated with reduced SN. CONCLUSIONS: This study suggests that cognitive reserve modulates functional connectivity in patients with FTD, even in monogenic disease. In GRN inherited FTD, cognitive reserve mechanisms operate even in presymptomatic to clinical stages.

    Full Text Available Background. Anti-neuronal autoimmunity may cause cognitive impairment that meets the criteria for dementia. Objective. Our aim was to detect the incidence and clinical features of autoimmune encephalitis imitating clinical findings of primary dementia disorders and to delineate the validity of anti-neuronal antibody screening in dementia patients. Methods. Fifty consecutive patients fulfilling the clinical criteria for primary dementia, 130 control patients, and 50 healthy controls were included. Their sera were investigated for several ion channel and glutamic acid decarboxylase (GAD antibodies by a cell-based assay, radioimmunoassay, and ELISA, as required. Results. Sixteen patients satisfying dementia criteria had atypical findings or findings suggestive of autoimmune encephalitis. N-methyl-D-aspartate receptor (NMDAR antibody was detected in a patient with dementia, Parkinsonism, and REM sleep behavior disorder (RBD fulfilling the criteria for dementia with Lewy bodies (DLB. One control patient with bipolar disease displayed low anti-GAD antibody levels. Conclusions. Our study showed for the first time the presence of parkinsonism and RBD in an anti-NMDAR encephalitis patient mimicking DLB. Although autoimmune encephalitis patients may occasionally present with cognitive decline, most dementia patients do not exhibit anti-neuronal antibodies, suggesting that routine analysis of these antibodies in dementia is not mandatory, even though they display atypical features.

    Preparations based on special extracts of the Ginkgo biloba tree are popular in various European countries. Previous studies have suggested the clinical efficacy of Ginkgo in patients with dementia, cerebral insufficiency, or related cognitive decline. However, most of these studies did not fulfill the current methodologic requirements. We assessed the efficacy of the G. biloba special extract EGb 761 in patients with dementia and age-associated memory impairment in relation to dose and duration of treatment. Our study was a 24-week, randomized, double-blind, placebo-controlled, parallel-group, multicenter trial. Study participants were elderly patients with dementia (Alzheimer disease or vascular dementia) or age-associated memory impairment (AAMI). A total of 214 participants, recruited from 39 homes for the elderly in the Netherlands, were randomly allocated to Ginkgo (either 240 mg/d or 160 mg/d) or placebo (0 mg/d). After 12 weeks, the subjects in the two Ginkgo groups were randomized to continued Ginkgo treatment or placebo treatment. Primary outcome measures in this study were the Syndrome Kurz Test (SKT; psychometric functioning), the Clinical Global Impression of change (CGI-2; psychopathology, assessed by nursing staff), and the Nuremberg Gerontopsychological Rating Scale for Activities of Daily Living (NAI-NAA; behavioral functioning). One hundred twenty-three patients received Ginkgo (n=79, 240 and 160 mg/d combined) or placebo (n=44) during the 24-week intervention period. We found no statistically significant differences in mean change of scores between Ginkgo and placebo. The differences were SKT: +0.4 (90% confidence interval [CI] -0.9-1.7); CGI-2: +0.1 (90% CI -0.3-0.4), and NAI-NAA: -0.4 (90% CI -1.9-1.2). A positive difference is in favor of Ginkgo. Neither the dementia subgroup (n=36) nor the AAMI subgroup (n=87) experienced a significant effect of Ginkgo treatment. There was no dose-effect relationship and no effect of prolonged Ginkgo

    Dementia is a clinical syndrome with abnormal degree of memory loss and impaired ability to recall events from the past often characterized by Alzheimer's disease. The various strategies to treat dementia need validation of novel compounds in suitable animal models for testing their safety and efficacy. These may include novel anti-amnesic drugs derived from synthetic chemistry or those derived from traditional herbal sources. Multiple approaches have been adopted to create reliable animal models ranging from rodents to non-human primates, where the animals are exposed to a predetermined injury or causing genetic ablation across specific regions of brain suspected to affect learning functions. In this review various animal models for Alzheimer's disease and treatment strategies in development of anti dementia drugs are discussed and an attempt has been made to provide a comprehensive report of the latest developments in the field.

    Hospitalized patients with advanced dementia often receive care that is of limited clinical benefit and inconsistent with preferences. We designed an Advanced Dementia Consult Service and conducted a pre and post pilot study to evaluate it in a Boston hospital. Consults were conducted by geriatricians and palliative care nurse practitioner. They consisted of structured consultation, counseling and provision of an information booklet to the family, and post-discharge follow-up with the family and primary care providers. Patients > 65 admitted with advanced dementia were identified and consults were solicited using pop-ups programmed into the computerized provider order entry (POE) system. In the initial 3-month period, patients received usual care (N=24). In the subsequent 3-month period, consults were provided to patients for whom it was requested (N=5). Data were obtained from the electronic medical record and proxies interviews (admission, 1-month post-discharge). The patients’ mean age in the combined sample (N=29) was 85.4, 58.6% were from nursing homes, and 86.2% of their proxies stated comfort was the goal of care. Nonetheless, their hospitalizations were characterized by high rates of intravenous antibiotics (86.2%), > 5 venipunctures (44.8%), and radiological exams (96.6%). Acknowledging the small sample size, there were trends towards better outcomes in the intervention group including: higher proxy knowledge of the disease, greater communication between proxies and providers, more advance care planning, lower re-hospitalization rates, and fewer feeding tube insertions after discharge. Targeted consultation for advanced dementia is feasible and may promote greater engagement of proxies and goal-directed care for patients after discharge. PMID:24219202

    2015-11-01

    Neurologists often struggle to interpret the results of neuropsychological testing, even though cognitive assessments are an integral component of the diagnostic process in dementia syndromes. This article reviews the principles underlying clinical neuropsychology, background on common neuropsychological tests, and tips on how to interpret the results when assessing patients with dementia. General cognitive screening tools, appropriate for use by general neurologists and psychiatrists, as well as specific cognitive tests examining the main cognitive domains (attention and orientation, memory, visuospatial function, language and executive function) in patients with dementia are considered. Finally, the pattern of deficits, helpful in defining clinical dementia phenotypes and sometimes in predicting the underlying molecular pathology, are outlined. Such clinicopathological associations will become invaluable as disease-modifying treatments for dementia are developed and implemented.

    Background: mortality statistics are a frequently used source of information on deaths in dementia but are limited by concerns over accuracy. Objective: to investigate the frequency with which clinically diagnosed dementia is recorded on death certificates, including predictive factors. Methods: a retrospective cohort study assembled using a large mental healthcare database in South London, linked to Office for National Statistics mortality data. People with a clinical diagnosis of dementia, aged 65 or older, who died between 2006 and 2013 were included. The main outcome was death certificate recording of dementia. Results: in total, 7,115 people were identified. Dementia was recorded on 3,815 (53.6%) death certificates. Frequency of dementia recording increased from 39.9% (2006) to 63.0% (2013) (odds ratio (OR) per year increment 1.11, 95% CI 1.07–1.15). Recording of dementia was more likely if people were older (OR per year increment 1.02, 95% CI 1.01–1.03), and for those who died in care homes (OR 1.89, 95% CI 1.50–2.40) or hospitals (OR 1.14, 95% CI 1.03–1.46) compared with home, and less likely for people with less severe cognitive impairment (OR 0.95, 95% CI 0.94–0.96), and if the diagnosis was Lewy body (OR 0.30, 95% CI 0.15–0.62) or vascular dementia (OR 0.79, 95% CI 0.68–0.93) compared with Alzheimer's disease. Conclusions: changes in certification practices may have contributed to the rise in recorded prevalence of dementia from mortality data. However, mortality data still considerably underestimate the population burden of dementia. Potential biases affecting recording of dementia need to be taken into account when interpreting mortality data. PMID:27146301

    2003-01-01

    Full Text Available Frontotemporal dementia (FTD is the third-leading cause of cortical dementia after Alzheimer's disease and Lewy body dementia, and is characterized by a dementia where behavioral disturbances are prominent and appear early in the course of the disease. We report the case of a 58 year-old man affected by dementia with behavioral disturbances, in addition to rigid-hypokinetic and a lower motor neuron syndrome that were present at later stages of the illness. Neuroimaging studies showed frontotemporal atrophy. Neuropathological studies revealed intense thalamic neuronal loss and astrocytic gliosis, as well as moderate frontotemporal neuronal loss, astrocytosis and spongiform degeneration. Thalamic degeneration has previously been described among the wide group of neuropathological features of FTD. The aim of the present study is to show the clinical and neuropathological aspects of thalamic degeneration in FTD, along with its role in behavioral disturbances, a common finding in this condition.

    The aim of this study was to evaluate the supportive role of molecular and structural biomarkers (CSF protein levels, FDG PET and MRI) in the early differential diagnosis of dementia in a large sample of patients with neurodegenerative dementia, and in determining the risk of disease progression in subjects with mild cognitive impairment (MCI). We evaluated the supportive role of CSF Aβ{sub 42}, t-Tau, p-Tau levels, conventional brain MRI and visual assessment of FDG PET SPM t-maps in the early diagnosis of dementia and the evaluation of MCI progression. Diagnosis based on molecular biomarkers showed the best fit with the final diagnosis at a long follow-up. FDG PET SPM t-maps had the highest diagnostic accuracy in Alzheimer's disease and in the differential diagnosis of non-Alzheimer's disease dementias. The p-tau/Aβ{sub 42} ratio was the only CSF biomarker providing a significant classification rate for Alzheimer's disease. An Alzheimer's disease-positive metabolic pattern as shown by FDG PET SPM in MCI was the best predictor of conversion to Alzheimer's disease. In this clinical setting, FDG PET SPM t-maps and the p-tau/Aβ{sub 42} ratio improved clinical diagnostic accuracy, supporting the importance of these biomarkers in the emerging diagnostic criteria for Alzheimer's disease dementia. FDG PET using SPM t-maps had the highest predictive value by identifying hypometabolic patterns in different neurodegenerative dementias and normal brain metabolism in MCI, confirming its additional crucial exclusionary role.

    Alcohol-related dementia (ARD) is one of the most common dementing disorders in middle-aged people and occurs in heavy drinkers who are estimated to be 10 - 15 % of the adult men in a community. While the concept of ARD is multifactorial and includes all cognitive deficits in alcoholics, the central clinical manifestations are exemplified by Korsakoff's syndrome (KS), a persistent neuropsychiatric syndrome, characterized by amnesia and disorientation that is caused by thiamine deficiency along with excessive alcohol consumption. Antemortem detection of intracranial changes has been made possible by MRI and many studies have revealed that alcoholics have atrophic changes in frontal lobe, cerebellum, medial temporal lobe and hippocampus. However, these brain regions are vulnerable to excessive alcohol and seem to be independent of cognitive deficits in alcoholics. This review shows the regional differences in gray matter volumes between cognitively normal alcoholics and patients with KS. By employing a 3-dimensional MRI method for voxel-based morphometry that enables an automated, unbiased, comprehensive assessment, we demonstrate that parahippocampal/hippocampal atrophy is specific to KS and thalamic atrophy and the third ventricle enlargement are more severe in patients with KS than in cognitively normal alcoholics.

    In a population-based study of dementia, the cost of care for 245 demented elderly and 490 controls matched by age and gender was estimated. Dementia of Alzheimer's type was diagnosed according to the NINCDS-ADRDA criteria, and vascular dementia and other types of dementia were diagnosed according...... to the DSM-IIIR criteria. Severity of dementia was determined by the Clinical Dementia Rating scale. The annual cost of medical care, domestic care, home help, nursing home and special equipment for nondemented patients was DKK 22,000 per person while the cost for very mildly, mildly, moderately and severely...... demented patients was DKK 49,000, DKK 93,000, DKK 138,000 and DKK 206,000, respectively. Except for very mild dementia the cost did not differ between elderly who suffer from Alzheimer's disease and those with other types of dementia.

    Conclusions: AD showed a faster rate of global brain atrophy compared to DLB, which had similar rates of atrophy to HC. Among dementia subjects, younger age was associated with accelerated atrophy, reflecting more aggressive disease in younger people. PBVC could aid in differentiating between DLB and AD, however its utility as an outcome marker in DLB is limited.

  9. Is drug treatment for dementia followed up in primary care? A Swedish study of dementia clinics and referring primary care centres.

    Lars Sonde

    Full Text Available PURPOSE: It is largely unknown how the medical treatment of patients diagnosed with dementia is followed up in primary care. Therefore, we studied patient medical records from two dementia clinics and from the referring primary care centres. METHODS: A retrospective study of 241 patients was conducted from April to October 2011 in north west Stockholm, Sweden. Over half (51.5% of the patients had Alzheimer's disease (AD, the remainder had mixed AD/vascular dementia (VaD. Eighty-four medical reports from primary care (35% of the study group were analysed at follow-up 18 months after diagnosis. RESULTS: All four dementia drugs available on the Swedish market (three cholinesterase inhibitors [donepezil, rivastigmine and galantamine] and memantine were prescribed at the two dementia clinics. The most commonly used dementia drug was galantamine. There were differences between the two dementia clinics in preference and combination of drugs and of treatment given to male and female patients. At follow-up, 84% were still on dementia medication. Drug use was followed up by the general practitioners (GPs in two-thirds of the cases. Eighteen per cent of the GPs' medical records made no reference to the patient's dementia or treatment even though dementia drugs were included in the list of medications prescribed. CONCLUSIONS: The results indicate that the Swedish guidelines for treatment of cognitive symptoms in AD are being followed in primary care. However, documentation of follow-up of drug treatment was sometimes insufficient, which calls for development of guidelines for complete medical records and medication lists.

    Full Text Available Background: The purpose of this study was to summarize published estimates for conversion from mild cognitive impairment or amnestic mild cognitive impairment to Alzheimer's dementia. We carried out a systematic review of English language publications to identify cohort studies published since January 2006 that reported the risk or rate of conversion. Summary: Thirty-two cohort studies were identified, of which 14 reported annualized conversion rates (ACRs. Conversions over 1 year ranged from 10.2 to 33.6% (5 studies, median: 19.0%, and over 2 years from 9.8 to 36.3% (7 studies, median: 18.6%. ACRs ranged from 7.5 to 16.5% (7 studies, median: 11.0% per person-year for studies recruiting from clinics, and from 5.4 to 11.5% (7 studies, median: 7.1% for community samples. Key Message: Extensive variation was observed in conversion rates due to the population sampled, diagnostic criteria, and duration, and because many studies did not account for loss to follow-up.

    The burden on those caring for a person with dementia is substantial. Although quality research assists in addressing the needs of these caregivers, recruiting caregivers into clinical studies is often problematic. This investigation explores the difficulties and successes in recruiting dementia caregivers into community-based clinical research by reporting the findings of a mixed-method substudy of a multicenter randomized controlled trial involving 40 community-dwelling dementia caregivers living in Adelaide, South Australia. Data for the substudy were derived from standardized trial monitoring documentation and structured telephone interviews. From a total of 16 distinct methods used across a 12-month recruitment campaign, the most cost-effective strategy was the distribution of flyers through a single study site. This approach generated the greatest number of enrollments of all methods used, achieving a 67% recruitment yield. The least cost-effective strategy, with a 0% recruitment yield, was the publication of a newspaper advertisement. Themes that emerged from the interviews pointed toward 5 key facilitators and 3 barriers to future trial recruitment. This study has generated new insights into the effective recruitment of dementia caregivers into clinical trials. We anticipate that these lessons learnt will assist in shaping the recruitment strategies of future studies of dementia caregivers.

    IMPORTANCE Late-onset Alzheimer disease (LOAD), defined as onset of symptoms after age 65 years, is the most common form of dementia. Few reports investigate incidence rates in large family-based studies in which the participants were selected for family history of LOAD. OBJECTIVE To determine the incidence rates of dementia and LOAD in unaffected members in the National Institute on Aging Genetics Initiative for Late-Onset Alzheimer Disease/National Cell Repository for Alzheimer Disease (NIA-LOAD/NCRAD) and Estudio Familiar de Influencia Genetica en Alzheimer (EFIGA) family studies. DESIGN, SETTING, AND PARTICIPANTS Families with 2 or more affected siblings who had a clinical or pathological diagnosis of LOAD were recruited as a part of the NIA-LOAD/NCRAD Family Study. A cohort of Caribbean Hispanics with familial LOAD was recruited in a different study at the Taub Institute for Research on Alzheimer’s Disease and the Aging Brain in New York and from clinics in the Dominican Republic as part of the EFIGA study. MAIN OUTCOMES AND MEASURES Age-specific incidence rates of LOAD were estimated in the unaffected family members in the NIA-LOAD/NCRAD and EFIGA data sets. We restricted analyses to families with follow-up and complete phenotype information, including 396 NIA-LOAD/NCRAD and 242 EFIGA families. Among the 943 at-risk family members in the NIA-LOAD/NCRAD families, 126 (13.4%) developed dementia, of whom 109 (86.5%) met criteria for LOAD. Among 683 at-risk family members in the EFIGA families, 174 (25.5%) developed dementia during the study period, of whom 145 (83.3%) had LOAD. RESULTS The annual incidence rates of dementia and LOAD in the NIA-LOAD/NCRAD families per person-year were 0.03 and 0.03, respectively, in participants aged 65 to 74 years; 0.07 and 0.06, respectively, in those aged 75 to 84 years; and 0.08 and 0.07, respectively, in those 85 years or older. Incidence rates in the EFIGA families were slightly higher, at 0.03 and 0.02, 0.06 and 0.05, 0

    Full Text Available Background: Dementia due to potentially reversible etiologies is an important group of dementias to be identified not only because of the number of such Patients encountered but also due to the potential for substantial improvement with treatment. Aims : To prospectively investigate the frequency and causes of dementias with potentially reversible etiologies; to examine the clinical features of this subgroup with a view to identifying a signature profile and to determine if this potential reversibility translates into actual reversibility with appropriate treatment. Setting and design : A prospective longitudinal study of patients with dementia presenting to the outpatient services of a tertiary referral hospital. Methods : All Patients above 40 years referred for evaluation of cognitive complaints were serially enrolled and underwent clinical examination, various laboratory tests and neuroimaging. Patients were followed-up for one year. Statistical analysis : One way analysis of variance for continuous variables followed by post hoc comparisons using Scheffe′s procedure. Results: A total of 129 patients met Diagnostic and Statistical Manual of Mental Disorders edition 4 (DSM IV criteria for dementia and qualified for inclusion into the study. Twenty-four patients (18%, all with moderately severe cognitive [mean mini mental state examination (MMSE score ± SD = 17.9 ± 4.8] and neuropsychiatric [mean neuropsychiatric inventory (NPI score ± SD = 30.7 ± 8.7] dysfunction were diagnosed to have reversible causes - neuroinfections in 11 patients, normal pressure hydrocephalus in 8 patients and vitamin B12 deficiency in 5 patients. The majority of these patients had gait and urinary dysfunction reminiscent of subcortical dementias. These reversible causes were clinically suspected in only 58% of patients. In 20/24 patients in whom follow up was possible mean MMSE score had improved to 22.2 and mean NPI score had improved to 8.0, following 6 months

    Dementia with Lewy bodies (DLB) is characterized by preserved whole brain and medial temporal lobe volumes compared with Alzheimer's disease dementia (AD) on magnetic resonance imaging. However, frequently coexistent AD-type pathology may influence the pattern of regional brain atrophy rates in DLB patients. We investigated the pattern and magnitude of the atrophy rates from 2 serial MRIs in autopsy-confirmed DLB patients (n = 20) and mixed DLB/AD patients (n = 22), compared with AD (n = 30) and elderly nondemented control subjects (n = 15), followed antemortem. DLB patients without significant AD-type pathology were characterized by lower global and regional rates of atrophy, similar to control subjects. The mixed DLB/AD patients displayed greater atrophy rates in the whole brain, temporoparietal cortices, hippocampus and amygdala, and ventricle expansion, similar to AD patients. In the DLB and DLB/AD patients, the atrophy rates correlated with Braak neurofibrillary tangle stage, cognitive decline, and progression of motor symptoms. Global and regional atrophy rates are associated with AD-type pathology in DLB, and these rates can be used as biomarkers of AD progression in patients with LB pathology.

    Frontotemporal dementia (FTD) is the second most common cause of young onset dementia. It is increasingly recognized that there is a clinical continuum between FTD and amyotrophic lateral sclerosis (ALS). At a clinical, pathological and genetic level there is much heterogeneity in FTD, meaning that our understanding of this condition, pathophysiology and development of treatments has been limited. A number of mouse models focusing predominantly on recapitulating neuropathological and molecular changes of disease have been developed, with most transgenic lines expressing a single specific protein or genetic mutation. Together with the species-typical presentation of functional deficits, this makes the direct translation of results from these models to humans difficult. However, understanding the phenotypical presentations in mice and how they relate to clinical symptomology in humans is essential for advancing translation. Here we review current mouse models in FTD and compare their phenotype to the clinical presentation in patients.

    The AIDS dementia complex (ADC, also referred to as HIV-associated cognitive impairment) is a common disorder among HIV-infected patients associated with both inflammatory and neurodegenerative processes. This review describes recent advances in the clinical and basic neurosciences of HIV infection and discusses the multivariable nature of what has become a chronic disorder in the context of highly active antiretroviral therapies (HAART). Since its initial description twenty years ago, advances in cell and molecular biology along with those in neuroimaging have furthered our understanding of the underlying pathogenic mechanisms. The clinical and neuropsychological profile of ADC is generally consistent with a "frontal-subcortical" pattern of injury. Neuropathogenesis is largely driven by indirect mechanisms mediated by infected, or more commonly, immune activated macrophages, which secrete viral and host-derived factors. Magnetic resonance spectroscopy (MRS) provides a robust in vivo method to measure the inflammatory and neurotoxic events triggered by these factors and their associated signals. Although the use of combined or highly active antiretroviral therapies (HAART) has significantly improved survival rates, cerebral injury and cognitive impairment remain common events. Factors such as aging and chronic infection will likely impact the course of this disease, its pathogenesis, and treatment. The combined observations presented in this review suggest a number of critical areas for future inquiry.

    Full Text Available Abstract Background Although extensive research exists on informal long-term care, little work has examined the clinical significance of transitions in family caregiving due to a lack of established clinical cut-points on key measures. The objectives of this study were to determine whether clinically significant changes in symptoms of burden and depression occur among caregivers within 12 months of nursing home admission (NHA of their relatives with dementia, and to identify key predictors of clinically persistent burden and depression in the first year after institutionalization. Methods Secondary longitudinal analysis of dementia caregivers were recruited from eight catchment areas in the United States with 6- and 12-month post-placement follow-up data. The sample included data on 1,610 dementia caregivers with pre- and six-month post-placement data and 1,116 with pre-placement, six-month, and 12-month post-placement data. Burden was measured with a modified version of the Zarit Burden Inventory. Depressive symptoms were assessed with the Geriatric Depression Scale. Results Chi-square analyses found significant (P Conclusions In addition to suggesting that clinically significant decreases in caregiver burden and depression are likely to occur following institutionalization, the results reveal particular subsets of caregivers who are at continued risk of distress. Such findings can facilitate development of screening processes to identify families at-risk following institutionalization.

    Full Text Available Introduction. Cognitive dysfunction as a core feature in the course of bipolar affective disorder (BPD is a current subject of debate and represents an important source of psychosocial and functional burden. Objectives. To stand out the connection and clinical implications between cognitive dysfunction, dementia, and BPD. Methods. A nonsystematic review of all English language PubMed articles published between 1995 and 2011 using the terms “bipolar disorder,” “cognitive dysfunction,” and “dementia”. Discussion. As a manifestation of an affective trait or stage, both in the acute phases and in remission, the domains affected include attention, executive function, and verbal memory. The likely evolution or overlap with the behavioural symptoms of an organic dementia allows it to be considered as a dementia specific to BPD. This is named by some authors, as BPD type VI, but others consider it a form of frontotemporal dementia. It is still not known if this process is neurodevelopmental or neurodegenerative in nature, or both simultaneously. The assessment should consider the iatrogenic effects of medication, the affective symptoms, and a neurocognitive evaluation. Conclusion. More specific neuropsychological tests and functional imaging studies are needed and will assume an important role in the near future for diagnosis and treatment.

    Full Text Available Abstract The aging of the population is a worldwide phenomenon, where 60% of elders live in developing areas of the world such as Brazil, regions in which few studies have been carried out. Objectives: The goal of this study was to evaluate the clinical and demographic profile of patients with dementing disorders seen at a specialized outpatient clinic in South Brazil. Methods: A sample of 105 demented patients seen at the Dementia Outpatient Clinic from Hospital de Clínicas de Porto Alegre (HCPA, Brazil between June 2004 and June 2008. Evaluation of patients consisted of medical history, cognitive testing, assessment of functional status (Activities of Daily Living Scale - ADL; Instrumental Activities Daily Living - IADL and application of the Neuropsychiatry Inventory (NPI for behavioral symptoms. Severity of dementia was evaluated based on the CDR scale. All patients underwent laboratory screening tests and brain imaging exams to define etiology of dementia. Results: Of the whole sample, 71% were female. Age was 79±8 years (mean±SD. Educational level was 4±3 years (mean±SD. Sixty-four patients (60% presented the diagnosis of Alzheimer's disease. Of the whole sample, 26.7% were classified as CDR=1, 44% as CDR=2 and 29. 3% as CDR=3. A significant difference on the Mini Mental State Examination (MMSE and functional status scores was observed among the CDR categories (severity. No significant association was found between severity and impairment on memory tests and behavioral symptoms. Conclusions: Alzheimer's disease was the most common etiology, followed by vascular dementia. At diagnosis, most patients presented mild to moderate severity of dementia, independent of cause.

    Thirty patients with degenerative dementia underwent clinical evaluation, neuropsychological testing, and single photon emission computed tomography (SPECT) with the blood flow tracer ({sup 123}I)-N-isopropyl-p-iodoamphetamine. Five of these patients were clinically and psychologically different from the others, demonstrating predominant behavioral disturbances with relative preservation of memory function. These five patients, who were felt to have a frontal lobe dementia (FLD), showed SPECT perfusion patterns which differed from the remaining 25 patients, who were diagnosed as having Alzheimer's disease (AD), and from 16 healthy control subjects. The FLD patients showed diminished perfusion in orbitofrontal, dorsolateral frontal, and temporal cortex relative to controls, while the AD patients showed lower perfusion in temporal and parietal cortex than controls. The FLD patients also showed hypoperfusion in both frontal cortical regions relative to AD patients. The pattern of performance on neuropsychological testing paralleled these differences in regional perfusion. These results suggest that clinical evaluation and physiological imaging may enable the differentiation of groups of degenerative dementia patients during life.

    2016-01-01

    Full Text Available Objectives: To determine changes over time in self and caregiver ratings of quality of life (QoL in people with dementia (PwD and to identify factors associated with changes in QoL ratings. Methods: In this longitudinal study, 69 people with mild Alzheimer’s disease and their caregivers were assessed at baseline and after 1 year. We examined the association of QoL ratings with the following variables at the two time points: awareness of disease, cognitive status, mood, functionality, neuropsychiatric symptoms, and caregiver burden. Multivariate regression analyses were conducted to examine the contribution of co-factors. Results: At baseline, PwD self-ratings of QoL were associated with caregiver ratings of PwD QoL (p = 0.001. Caregiver ratings were associated with PwD mood (p = 0.001 and self-rated QoL (p = 0.001. After 1 year, caregiver ratings of PwD QoL changed significantly (p = 0.049, d = -0.27, whereas PwD self-ratings did not (p = 0.89, d = 0.09. PwD awareness of disease changed significantly (p = 0.001 at 1 year, having declined in 25.4% and improved in 12.3% of participants. PwD QoL self-ratings were associated with caregiver ratings (p = 0.001. Caregiver ratings of PwD QoL after 1 year were associated with PwD mood (p = 0.029, self-reported QoL (p = 0.001, and awareness of disease (p = 0.033. Conclusions: The association between self and caregiver ratings of PwD QoL was maintained over 1 year. The primary factors accounting for the change in caregiver ratings were PwD mood and awareness of disease. QoL and cognitive impairment seem to be relatively independent in mild dementia.

    Full Text Available Some studies have tried to assess the Mattis Dementia Rating Scale (MDRS capability to detect incipient dementia or Mild Cognitive Impairment (MCI, but the results are not clear. The aim of this research was to evaluate the sensitivity and specificity of the MDRS, and to localize the optimal cutoff score for MCI. Methodology. A neuropsychological battery that included the MDRS was administered to 60 older adults of both genders (Mean age=68.38, SD=6.80 in Cór- doba, Argentina, who were then classified as “Control” (34 cases or “MCI” (26 cases according to performance in the neuropsychological evaluation, excluding the MDRS. The criteria used were those stated by the Sociedad Española de Neurología. We performed mean comparisons in order to evaluate if the MDRS was able to detect the group differences. Then, a logistic regression with the MDRS total score as the predictor variable and the group as the criterion variable was performed to determine the cutoff score. Results. Even though the mean comparisons showed a significant difference in the MDRS (p=.004, the diagnostic accuracy was only 63% with a 133 points cutoff score. The sensitivity was 42% and the specificity was 79%. Conclusions. The MDRS does not seem to be a useful tool to detect MCI since it generates numerous misclassified cases. The development of more accurate tools becomes fundamental in order to detect MCI.

    Dementia is the progressive loss of intellectual functions due to involvement of cortical or subcortical areas. Specific involvement of certain brain areas in the different diseases leads to impairment of different functions, e. g., memory, language, visuospatial abilities, and behavior. Magnetic resonance imaging and other neuroradiological studies may indicate which structures are mainly or selectively involved in a demented patient, thus allowing clinical-radiological correlations. Clinical presentation and evolution of the disease, supported by imaging studies, may lead to a highly probable diagnosis. The most common disorders, or the most relevant from the neuroradiological point of view, such as Alzheimer's disease, frontotemporal dementia, vascular dementias, dementia associated with parkinsonism, Huntington's disease, Creutzfeldt-Jakob disease, and normal-pressure hydrocephalus, are briefly discussed.

    Full Text Available Current dementia medications have small effect sizes, many adverse effects and do not change the disease course. Therefore, it is critically important to study alternative treatment strategies. The goal of this study was to pilot-test a novel, integrative group exercise program for individuals with mild-to-moderate dementia called Preventing Loss of Independence through Exercise (PLIÉ, which focuses on training procedural memory for basic functional movements (e.g., sit-to-stand while increasing mindful body awareness and facilitating social connection.We performed a 36-week cross-over pilot clinical trial to compare PLIÉ with usual care (UC at an adult day program for individuals with dementia in San Francisco, CA. Assessments of physical performance, cognitive function, physical function, dementia-related behaviors, quality of life and caregiver burden were performed by blinded assessors at baseline, 18 weeks (cross-over and 36 weeks.

    Intimacy and sexuality expressed by nursing home residents with dementia remains an ethically sensitive issue for care facilities, nursing staff and family members. Dealing with residents' sexual longings and behaviour is extremely difficult, putting a burden on the caregivers as well as on the residents themselves and their relatives. The parties in question often do not know how to react when residents express themselves sexually. The overall aim of this article is to provide a number of clinical-ethical considerations addressing the following question: 'How can expressions of intimacy and sexuality by residents with dementia be dealt with in an ethically responsible way?' The considerations formulated are based on two cornerstones: (1) the current literature on older peoples' experiences regarding intimacy and sexuality after the onset of dementia, and (2) an anthropological-ethical framework addressing four fundamental pillars of human existence namely the decentred self, human embodiment, being-in-the-world and being-with-others. The resulting considerations are oriented toward the individual sphere, the partnership sphere, and the institutional sphere. The continuous interaction between these spheres leads to orientations that both empower the residents in question and respect the complex network of relationships that surrounds them.

    Full Text Available Objective: To critically review and evaluate existing knowledge on the conceptual limits and clinical usefulness of the diagnosis of mild cognitive impairment (MCI and the neuropsychological assessment and short- and long-term prognosis thereof. Methods: We conducted a systematic search of the PubMed and Web of Science electronic databases, limited to articles published in English between 1999 and 2012. Based on the search terms mild cognitive impairment or MCI and epidemiology or diagnosis, we retrieved 1,698 articles, of which 248 were critically eligible (cross-sectional and longitudinal studies; the abstracts of the remaining 1,450 articles were also reviewed. Results: A critical review on the MCI construct is provided, including conceptual and diagnostic aspects; epidemiological relevance; clinical assessment; prognosis; and outcome. The distinct definitions of cognitive impairment, MCI included, yield clinically heterogeneous groups of individuals. Those who will eventually progress to dementia may present with symptoms consistent with the definition of MCI; conversely, individuals with MCI may remain stable or return to normal cognitive function. Conclusion: On clinical grounds, the cross-sectional diagnosis of MCI has limited prognostic relevance. The characterization of persistent and/or progressive cognitive deficits over time is a better approach for identification of cases at the pre-dementia stages, particularly if these cognitive abnormalities are consistent with the natural history of incipient Alzheimer's disease.

    Full Text Available Objective: The aim of this study was to determine which characteristics could better distinguish dementia with Lewy bodies (DLB from Alzheimer's disease (AD at the mild cognitive impairment (MCI stage, with particular emphasis on visual space and object perception abilities. Methods: Fifty-three patients with mild cognitive deficits that were eventually diagnosed with probable DLB (MCI-DLB: n = 25 and AD (MCI-AD: n = 28 at a 3-year follow-up were retrospectively studied. At the first visit, the patients underwent cognitive assessment including the Qualitative Scoring Mini Mental State Examination Pentagon Test and the Visual Object and Space Perception Battery. The Neuropsychiatric Inventory Questionnaire, Unified Parkinson's Disease Rating Scale (UPDRS and questionnaires for cognitive fluctuations and sleep disorders were also administered. Results: The best clinical predictor of DLB was the presence of soft extrapyramidal signs (mean UPDRS score: 4.04 ± 5.9 detected in 72% of patients, followed by REM sleep behavior disorder (60% and fluctuations (60%. Wrong performances in the pentagon's number of angles were obtained in 44% of DLB and 3.7% of AD patients and correlated with speed of visual attention. Executive functions, visual attention and visuospatial abilities were worse in DLB, while verbal episodic memory impairment was greater in AD. Deficits in the visual-perceptual domain were present in both MCI-DLB and AD. Conclusions: Poor performance in the pentagon's number of angles is specific of DLB and correlates with speed of visual attention. The dorsal visual stream seems specifically more impaired in MCI-DLB with respect to the ventral visual stream, the latter being involved in both DLB and AD. These cognitive features, associated with subtle extrapyramidal signs, should alert clinicians to a diagnostic hypothesis of DLB.

    BACKGROUND: Cognitive impairment and dementia has been reported in autosomal dominant hereditary spastic paraparesis (HSP) linked to the SPG4 locus. There has only been one postmortem examination described; not all accept that progressive cognitive decline is a feature of this disorder. OBJECTIVE: A family with SPG4-HSP known to have a deletion of exon 17 in the spastin gene (SPG4delEx17) was cognitively assessed over a 7-year period. The index family member died and a postmortem examination was performed. METHODS: Thirteen family members older than 40 years were clinically and cognitively assessed using the Cambridge Cognitive Assessment over a 7-year period. The presence of SPG4delEx17 was assessed; a neuropathologic examination of the brain of the index family member was performed. RESULTS: Cognitive decline occurred in 6 of the 13 family members and in all 4 older than 60 years. Two genetic deletions were identified: SPG4delEx17 in 12 of the 13 family members and a deletion of SPG6 (SPG6del) in 5. Eight individuals had the SPG4delEx17 deletion only; 4 had evidence of progressive cognitive impairment. Four family members had both SPG4delEx17 and SPG6del; 2 of these had cognitive impairment. One family member with the SPG6del alone had neither HSP nor cognitive impairment. The index case with both deletions died with dementia; the brain showed widespread ubiquitin positivity within the neocortex and white matter. CONCLUSION: Cognitive decline and dementia is a feature of SPG4-HSP due to a deletion of exon 17 of the spastin gene.

    Full Text Available A 61-year-old ex-boxer presented with a three-year history of progressive memory decline. During a seven-year follow-up period, there was a continuous cognitive decline, very similar to that usually observed in Alzheimer's disease. Parkinsonian, pyramidal or cerebellar signs were conspicuously absent. Neuropathological examination revealed the typical features of dementia pugilistica: cavum septi pellucidi with multiple fenestrations, numerous neurofibrillary tangles in the cerebral isocortex and hippocampus (and rare senile plaques. Immunohistochemistry disclosed a high number of tau protein deposits and scarce beta-amyloid staining. This case shows that dementia pugilistica may present with clinical features practically undistinguishable from Alzheimer's disease.Um ex-boxeador de 61 anos apresentou-se com história de três anos de perda progressiva de memória e evoluiu com declínio cognitivo lentamente progressivo, sugestivo de doença de Alzheimer, durante seguimento de sete anos.

    To elucidate clinical significance of white matter hyperintensities (WMH) in MRI, fifty patients with senile dementia of the Alzheimer type (SDAT) and twenty normal controls were studied. Twenty nine patients with SDAT (58.0%) had periventricular hyperintensities (PVH) and twenty three patients with SDAT (46.0%) had deep white matter hyperintensities (DWMH). Eight controls (40.0%) had PVH and ten controls (50.0%) had DWMH. There were no significant differences in frequency of WMH between patients with SDAT and normal controls. Past history of hypertension was more frequent in patients with PVH or DWMH than in patients without them. Serum cholesterol level was higher in patients with DWMH than in patients without them. However there were no significant differences in the other clinical features between patients with WMH and patients without them. The results of present study suggest that DWMH in patients with SDAT is associated with cerebrovascular risk factors such as hypertension and hyperlipidemia. (author)

    Decreased striatal dopamine transporter (DAT) binding on SPECT imaging is a strong biomarker for the diagnosis of dementia with Lewy bodies (DLB). There is still a lot of uncertainty about patients meeting the clinical criteria for probable DLB who have a normal DAT SPECT scan (DLB/S-). The aim of this study was to describe the clinical and imaging follow-up in these patients, and compare them to DLB patients with abnormal baseline scans (DLB/S+). DLB patients who underwent DAT imaging ([{sup 123}I]FP-CIT SPECT) were selected from the Amsterdam Dementia Cohort. All [{sup 123}I]FP-CIT SPECT scans were evaluated independently by two nuclear medicine physicians and in patients with normal scans follow-up imaging was obtained. We matched DLB/S- patients for age and disease duration to DLB/S+ patients and compared their clinical characteristics. Of 67 [{sup 123}I]FP-CIT SPECT scans, 7 (10.4 %) were rated as normal. In five DLB/S- patients, a second [{sup 123}I]FP-CIT SPECT was performed (after on average 1.5 years) and these scans were all abnormal. No significant differences in clinical characteristics were found at baseline. DLB/S- patients could be expected to have a better MMSE score after 1 year. This study was the first to investigate DLB patients with the initial [{sup 123}I]FP-CIT SPECT scan rated as normal and subsequent scans during disease progression rated as abnormal. We hypothesize that DLB/S- scans could represent a relatively rare DLB subtype with possibly a different severity or spread of alpha-synuclein pathology (''neocortical predominant subtype''). In clinical practice, if an alternative diagnosis is not imminent in a DLB/S- patient, repeating [{sup 123}I]FP-CIT SPECT should be considered. (orig.)

    Objective: To observe the therapeutic effect and mechanism of Naohuandan (脑还丹, NHD)in treating senile dementia (SD). Methods: Clinical study: Fifty-eight patients with SD, whose diagnosis conforms to the Diagnostic Standard of DSM-Ⅳ issued by American Association of Psychiatry, were enrolled and randomly assigned into two groups. The 30 patients in the treated group were treated with NHD, 4 capsules each time, 3 times daily. The 28 patients in the control group were treated with Piracetam, 1.6 g each time, 3 times daily. The therapeutic course for both groups was 3 months. The therapeutic efficacy was estimated and compared by comprehensive scores of memory and cognition, scores of Mini-mental State Examination (MMSE) and Activities of Daily Living (ADL). Experimental study: Rats were divided into the control group,the model group and the high-dosage and Iow-dosage NHD treated groups. The protective effect of NHD on the per-oxidative damage of hippocampal neurons in β-amyloid protein induced SD model was observed and the related criteria were determined. Results: Clinical study showed that both NHD and Piracetam could improve the clinical symptoms of patients, the two medicines showing insignificant difference in total effective rate. But NHD was better in elevating MMSE score and lowering ADL score in patients than Piracetam ( P<0.05 and P<0.01). Experimental study showed that (1) 24 and 72 hrs after modeling, the activity of SOD and GSH were lower and the level of MDA higher in the model group than those in the control group ( P<0.05or P<0.01). Compared with the model group at the corresponding time points, in the high-dosage NHD group, SOD and GSH were higher, MDA was lower ( P<0.05 or P<0.01); but in the Iow-dosage NHD group, SOD at the 72th hr was higher (P<0.05) and MDA at 24th and 72th hrs was lower ( P<0.01). And most of the criteria in the high-dosage NHD group was improved better than that in the Iow-dosage NHD group. ( 2) The

    Full Text Available Abstract Dementia is a clinical state characterized by loss of function in multiple cognitive domains. It is a costly disease in terms of both personal suffering and economic loss. Frontotemporal dementia (FTD is the term now preferred over Picks disease to describe the spectrum of non-Alzheimers dementias characterized by focal atrophy of the frontal and anterior temporal regions of the brain. The prevalence of FTD is considerable, though specific figures vary among different studies. It occurs usually in an age range of 35–75 and it is more common in individuals with a positive family history of dementia. The risk factors associated with this disorder include head injury and family history of FTD. Although there is some controversy regarding the further syndromatic subdivision of the different types of FTD, the three major clinical presentations of FTD include: 1 a frontal or behavioral variant (FvFTD, 2 a temporal, aphasic variant, also called Semantic dementia (SD, and 3 a progressive aphasia (PA. These different variants differ in their clinical presentation, cognitive deficits, and affected brain regions. Patients with FTD should have a neuropsychiatric assessment, neuropsychological testing and neuroimaging studies to confirm and clarify the diagnosis. Treatment for this entity consists of behavioral and pharmacological approaches. Medications such as serotonin reuptake inhibitors, antipsychotics, mood stabilizer and other novel treatments have been used in FTD with different rates of success. Further research should be directed at understanding and developing new diagnostic and therapeutic modalities to improve the patients' prognosis and quality of life.

    The apolipoprotein E epsilon 4 allele (ApoE-ε4) is the strongest known genetic risk factor for late onset Alzheimer's disease. Expansion of the lateral ventricles occurs with normal aging, but dementia accelerates this process. Brain structure and function depend on ApoE genotype not just for Alzheimer's disease patients but also in healthy elderly individuals, and even in asymptomatic young individuals. Therefore, we hypothesized that the ApoE-ε4 allele is associated with altered patterns of longitudinal ventricular expansion, in dementia and normal aging. We tested this hypothesis in a large sample of elderly participants, using a linear discriminant analysis-based approach. Carrying more ApoE-ε4 alleles was associated with faster ventricular expansion bilaterally and with regional patterns of lateral ventricle morphology at 1- and 2-year follow up, after controlling for sex, age, and dementia status. ApoE genotyping is considered critical in clinical trials of Alzheimer's disease. These findings, combined with earlier investigations showing that ApoE is also directly implicated in other conditions, suggest that the selective enrollment of ApoE-ε4 carriers may empower clinical trials of other neurological disorders.

    Full Text Available In cortical Lewy body dementia the distribution of Lewy bodies in the nervous system follows that of Parkinson's disease, except for their greater profusion in the cerebral cortex. The cortical tangles and plaques of Alzheimer pathology are often present, the likely explanation being that Alzheimer pathology provokes dementia in many patients. Pure cortical Lewy body dementia without Alzheimer pathology is uncommon. The age of onset reflects that of Parkinson's disease, and clinical features, though not diagnostic, include aphasias, apraxias, agnosias, paranoid delusions and visual hallucinations. Parkinsonism may present before or after the dementia, and survival duration is approximately half that seen in Parkinson's disease without dementia.

    Introduction Classic chronic inflammatory demyelinating polyneuropathy (CIDP), an acquired demyelination of peripheral nerves and nerve roots presents with symmetric motor and sensory involvement, weakness in proximal and distal muscles, globally diminished or absent reflexes, painful dysesthesias, and back pain with no brain involvement. In this case, a highly functional lawyer presents with reversible dementia and motor and sensory symptoms consistent with CIDP. This case may represent a new clinical entity of CIDP with reversible dementia. Case Report A 60-year-old man presented with progressive weakness, and cognitive dysfunction in the form of dementia over the last 8 weeks. Sensory and motor weakness continued to progress affecting upper and lower extremities with both proximal and distal muscle groups to the point where the patient was unable to move without assistance. The patient had word finding difficulty, short-term memory impairment, and was disoriented, despite his comprehension being intact. Initial Montreal Cognitive Assessment (MoCA) was 12/30. Initial neurologic exam was notable for muscle strength 3/5, globally depressed deep tendon reflexes. Lumbar puncture revealed elevated protein with no pleocytosis and no serum paraprotein. EMG/NCS demonstrated mixed sensorimotor axonal and demyelination peripheral polyneuropathy. CIDP was diagnosed based on clinical history according to Koski criteria. He was started on a 5-day treatment of IVIG, after which he had marked cognitive improvement after just one dose and improvement in weakness after the second dose of IVIG. Three weeks after IVIG treatment, the patient's cognitive function was back at baseline with MoCA score 29/30; no further word finding difficulty, and no short term memory impairment. At discharge, the patient's weakness had significantly improved to the point where he was able to walk with only the aid of a walker. His neurologic exam had improved as well as his muscle strength 4/5 and 2

    We assessed the effects of music therapy (MT) on behavioral and psychological symptoms (BPSD) in dementia associated with changes in physiological parameters, as heart rate (HR) and heart rate variability (HRV). Twenty subjects were randomly assigned to MT treatment or standard care; all patients underwent neuropsychological assessment and ECG Holter recordings before and after the 15-week treatment. The treatment included 30 MT sessions. Depression significantly decreased (p=0.021) in the MT group. PNN50 improved in 50% patients of the MT group, but in none of the control group (p=0.013). MT may improve symptoms of depression and increase HRV in demented patients.

    Huntington's disease is an incurable, adult-onset, autosomal dominant inherited disorder caused by an expanded trinucleotide repeat (CAG). In this study, we describe a Huntington's disease patient displaying clinical symptoms of the behavioural variant of frontotemporal dementia in the absence of tremor and ataxia. The clinical onset was at the age of 36 years and the disease progressed slowly (18 years). Genetic testing revealed expanded trinucleotide CAG repeats in the Huntingtin gene, together with a Glu318Gly polymorphism in presenilin 1. Neuropathological assessment revealed extensive amyloid β (Aβ) aggregates in all cortical regions. No inclusions displaying hyperphosphorylated tau or phosphorylated transactive response DNA-binding protein 43 (TDP43) were found. A high number of p62 (sequestosome 1) immunopositive intranuclear inclusions were seen mainly in the cortex, while subcortical areas were affected to a lesser extent. Confocal microscopy revealed that the majority of p62 intranuclear lesions co-localised with the fused-in-sarcoma protein (FUS) immunostaining.

    Mutations in the progranulin gene (GRN) were recently identified as an important cause of familial frontotemporal dementia (FTD). More than 60 pathogenic mutations have been reported up to now and prominent phenotypic variability within and among affected kindreds has been described. We have studied an Italian family with clinical evidence of dementia, and here we report detailed clinical records, imaging, sequential neurological examinations, cognitive assessments, and genetic analysis of three affected members of the same generation. Genetic analysis revealed the presence of the null mutation IVS6 + 5_8delGTGA in GRN, leading to haploinsufficiency, as documented by mRNA analysis. The mutation is associated with wide variation of the clinical phenotype, ranging from FTD to Alzheimer's disease and to a rapidly-progressive dementia. In summary, the patients of this kindred showed highly variable clinical features that do not have a close correspondence with the pattern of the cerebral atrophy. Our data extend the phenotypic spectrum and the complexity of neurodegenerative diseases linked to GRN mutations.

    Full Text Available Background: Nicotine dependence is an important public health issue. Nicotine dependence is a risk factor for vascular diseases like myocardial infarction and vascular dementia. The rate of nicotine dependence in Indian subjects with vascular dementia is not known. Hence we decided to assess nicotine dependence in subjects with vascular dementia. Methods: Nicotine dependence in subjects with vascular dementia was assessed among subjects presenting to memory clinic of a tertiary care hospital over a period of 16 months. Data regarding sociodemographic profile and severity of nicotine dependence as per Fagerstrom nicotine dependence scale for smoking and smokeless tobacco was analysed using SPSS version 17. Results: Our study shows that in 159 subjects with vascular dementia continuing nicotine dependence was seen in nearly 12% of the subjects. Though the rates are less than the population prevalence for India, it is still relevant as nicotine is not just a risk factor for development of vascular dementia but severe nicotine dependence and longer duration of nicotine use were found to be poor prognostic factors associated with severe dementia. Further as all subjects continued to be nicotine dependent despite having been advised to quit tobacco, suggesting the need for a more comprehensive tobacco cessation intervention be offered to subjects with vascular dementia to improve outcomes. Conclusion: In subjects with vascular dementia continuing nicotine dependence is an important risk factor which must be addressed. [Int J Res Med Sci 2015; 3(3.000: 711-714

    BACKGROUND: It has been suggested that antidepressants may have neuroprotective abilities but it has newer been investigated lately whether treatment with antidepressants reduces the risk of dementia. METHOD: Linkage of registers of all prescribed antidepressants and diagnoses of dementia...... in Denmark during a period from 1995 to 2005. RESULTS: Persons who purchased antidepressants once (N=687,552) had an increased rate of dementia compared to persons unexposed to antidepressants (N=779,831). Nevertheless, the rate of dementia changed over time; thus during the initial prescription periods...... the rate increased with the number of prescriptions but continued long-term antidepressants treatment was associated with a reduction in the rate of dementia, however, not to the same level as the rate for the general population. This pattern was found for all classes of antidepressants (SSRIs, newer non...

  10. Atrial Fibrillation, Cognitive Decline And Dementia

    Science.gov (United States)

    Alonso, Alvaro; Arenas de Larriva, Antonio P.

    2016-01-01

    Atrial fibrillation (AF) is a common cardiac arrhythmia. Growing evidence supports a role for AF as a risk factor for cognitive decline and dementia. In this review, we summarize epidemiologic observations linking AF with cognitive outcomes, describe potential mechanisms, and explore the impact of AF treatments on cognitive decline and dementia. Community-based, observational studies show a consistent higher rate of cognitive decline and risk of dementia in persons with AF. These associations are partly due to the increased risk of clinical stroke in AF, but other mechanisms, including incidence of silent cerebral infarcts, microbleeds, and cerebral hypoperfusion, are likely additional contributors. Adequate oral anticoagulation and improved management of the overall cardiovascular risk profile in persons with AF offer the promise of reducing the impact of AF on cognitive decline and dementia.

    Directory of Open Access Journals (Sweden)

    Leandro Boson Gambogi

    Full Text Available ABSTRACT Chronic mania is an under-investigated condition and few reports have associated this disorder with an organic background. The present work examines Kraepelin’s reliable description of chronic mania from a current behavioral neurology viewpoint. Kraepelin had described a cluster of symptoms that are now recognized as core manifestations of the behavioral variant frontotemporal dementia (bvFTD clinical phenotype. We also carried out additional reviews of original manuscripts from Kraepelin’s peers, in order to find any case reports that might fulfill the current diagnostic proposal for bvFTD. Even though we failed to find an ideal case, we found some scholars who seemed to agree that chronic mania should be considered a special form of dementia. The present work highlights, through historical data, the possible overlapping features between primary psychiatric disorders and neuropsychiatric symptoms secondary to neurodegenerative conditions.

    Aim: To observe the therapeutic effect of electroacupuncture (EA) in the treatment of vascular dementia. Methods: A total of 46 cases of vascular dementia (VD) patients were divided into 3 classes according to the scores of the revised Hasegawa dementia scale (HDS), and then randomized into EA group (n=23) and medication (Nimodipine) group (n=23). The acupoints used were "Zhisanzhen" [Shenting (GV 24) and bilateral Benshen (GB 13)] and Sishenchong (EX-HN 1) etc.. Scores of HDS, ability of daily life (ADL), neurofunctional defect and main symptoms were used as the indexes for assessing the therapeutic effect. Results: Following treatment, scores of HDS and ADL of two groups increased significantly, while those of neurofunctional defect and main symptoms decreased evidently (P<0.01), and the therapeutic effect of EA was obviously superior to that of medication (P<0.01). Conclusion: EA of "Zhisanzhen" and Sishenchong (EX-HN 1) is a good approach for treatment of VD.

    Dementia with Lewy bodies (DLB) is widely recognized as the second commonest form of degenerative dementia. Its core clinical features include persistent visual hallucinosis, fluctuating cognitive impairment and parkinsonism. We evaluated the brain perfusion of dementia with Lewy bodies by SPM analysis and correlated the findings with clinical symptom. Twelve DLB patients (mean age ; 68.88.3 yrs, K-MMSE ; 17.36) and 30 control subjects (mean age ; 60.17.7 yrs) were included. Control subjects were selected by 28 items of exclusion criteria and checked by brain CT or MRI except 3 subjects. Tc-99m HMPAO brain perfusion SPECT was performed and the image data were analyzed by visual interpretation and SPM99 as routine protocol. In visual analysis, 7 patients showed hypoperfusion in both frontal, temporal, parietal and occipital lobe, 2 patients in both frontal, temporal and parietal lobe, 2 patients in both temporal, parietal and occipital lobe, 1 patients in left temporal, parietal and occipital lobe. In SPM analysis (uncorrected p<0.01), significant hypoperfusion was shown in Lt inf. frontal gyrus (B no.47), both inf. parietal lobule (Rt B no.40), Rt parietal lobe (precuneus), both sup. temporal gyrus (Rt B no.42), Rt mid temporal gyrus, Lt transverse temporal gyrus (B no.41), both para hippocampal gyrus, Rt thalamus (pulvinar), both cingulate gyrus (Lt B no.24, Lt B no.25, Rt B no.23, Rt B no.24, Rt B no.33), Rt caudate body, both occipital lobe (cuneus, Lt B no.17, Rt B no.18). All patients had fluctuating cognition and parkinsonism, and 9 patients had visual hallucination. The result of SPM analysis was well correlated with visual interpretation and may be helpful to specify location to correlate with clinical symptom. Significant perfusion deficits in occipital region including visual cortex and visual association area are characteristic findings in DLB. Abnormalities in these areas may be important in understanding symptoms of visual hallucination and

It includes information about the diagnostic work-up, medical treatment and community support (www.svedem.se. The patients are diagnosed and followed-up yearly in specialist units, primary care centres or in nursing homes.The database was initiated in May 2007 and covers almost all of Sweden. There were 28 722 patients registered with a mean age of 79.3 years during 2007-2012. Each participating unit obtains continuous online statistics from its own registrations and they can be compared with regional and national data. A report from SveDem is published yearly to inform medical and care professionals as well as political and administrative decision-makers about the current quality of diagnostics, treatment and care of patients with dementia disorders in Sweden.SveDem provides knowledge about current dementia care in Sweden and serves as a framework for ensuring the quality of diagnostics, treatment and care across the country. It also reflects changes in quality dementia care over time. Data from SveDem can be used to further develop the national guidelines for dementia and to generate new research hypotheses.

    The burden of chronic disease is greater in individuals with dementia, a patient group that is growing as the population is aging. The cornerstone of optimal management of chronic disease requires effective patient self-management. However, this is particularly challenging in older persons with a comorbid diagnosis of dementia. The impact of dementia on a person’s ability to self-manage his/her chronic disease (eg, diabetes mellitus or heart failure) varies according to the cognitive domain(s) affected, severity of impairment and complexity of self-care tasks. A framework is presented that describes how impairment in cognitive domains (attention and information processing, language, visuospatial ability and praxis, learning and memory and executive function) impacts on the five key processes of chronic disease self-management. Recognizing the presence of dementia in a patient with chronic disease may lead to better outcomes. Patients with dementia require individually tailored strategies that accommodate and adjust to the individual and the cognitive domains that are impaired, to optimize their capacity for self-management. Management strategies for clinicians to counter poor self-management due to differentially impaired cognitive domains are also detailed in the presented framework. Clinicians should work in collaboration with patients and care givers to assess a patient’s current capabilities, identify potential barriers to successful self-management and make efforts to adjust the provision of information according to the patient’s skill set. The increasing prevalence of age-related chronic illness along with a decline in the availability of informal caregivers calls for innovative programs to support self-management at a primary care level.

  1. Treatment of dementia with neurotransmission modulation.

    Doggrell, Sheila A; Evans, Suzanne

    2003-10-01

    The prevalence of dementia is growing in developed countries where elderly patients are increasing in numbers. Neurotransmission modulation is one approach to the treatment of dementia. Cholinergic precursors, anticholinesterases, nicotine receptor agonists and muscarinic M(2) receptor antagonists are agents that enhance cholinergic neurotransmission and that depend on having some intact cholinergic innervation to be effective in the treatment of dementia. The cholinergic precursor choline alfoscerate may be emerging as a potential useful drug in the treatment of dementia, with few adverse effects. Of the anticholinesterases, donepezil, in addition to having a similar efficacy to tacrine in mild-to-moderate Alzheimer's disease (AD), appears to have major advantages; its use is associated with lower drop-out rates in clinical trials, a lower incidence of cholinergic-like side effects and no liver toxicity. Rivastigmine is efficacious in the treatment in dementia with Lewy bodies, a condition in which the other anticholinesterases have not been tested extensively to date. Galantamine is an anticholinesterase and also acts as an allosteric potentiating modulator at nicotinic receptors to increase the release of acetylcholine. Pooled data from clinical trials of patients with mild-to-moderate AD suggest that the benefits and safety profile of galantamine are similar to those of the anticholinesterases. Selective nicotine receptor agonists are being developed that enhance cognitive performance without influencing autonomic and skeletal muscle function, but these have not yet entered clinical trial for dementia. Unlike the cholinergic enhancers, the M(1) receptor agonists do not depend upon intact cholinergic nerves but on intact M(1) receptors for their action, which are mainly preserved in AD and dementia with Lewy bodies. The M(1) receptor-selective agonists developed to date have shown limited efficacy in clinical trials and have a high incidence of side effects. A

    Full Text Available The proportion of male caregivers is rapidly increasing. However, there are few large scale studies exploring gender differences in the burden or coping with caregiving. We investigated this among caregivers of patients with dementia. The study cohort consisted of 335 dyads of wife-husband couples from two studies including dementia patients and their spousal caregivers. Baseline mini-mental state examination (MMSE, clinical dementia rating scale (CDR, neuropsychiatric inventory (NPI, cornell depression scale and charlson comorbidity index (CCI were used to describe patients with dementia, Zarit burden scale and geriatric depression scale were used to measure experienced burden and depression of caregivers. Mean age of caregivers was 78 years. There were no differences in depression, satisfaction with life, or loneliness according to caregivers' gender. Male caregivers had more comorbidities than females (CCI 1.9 versus 1.1, P<0.001, and the wives of male caregivers had a more severe stage of dementia than husbands of female caregivers (CDR, P=0.048; MMSE14.0 versus 17.7, P<0.001. However, the mean Zarit burden scale was significantly lower among male than female caregivers (31.5 versus 37.5; P<0.001. Lower education of male caregivers tended to be associated with less experienced burden. In conclusion, male caregivers of dementia experienced lower burden than female caregivers despite care recipients' more severe disease.

    The segment of older adults who present to the emergency department (ED) with cognitive impairment ranges from 21% to 40%. Difficulties inherent in the chaotic ED setting combined with dementia may result in a number of unwanted clinical outcomes, but strategies to minimize these outcomes are lacking. A review of the literature was conducted to examine the practices undertaken in the care of persons with dementia (PWD) specific to the ED setting. PubMed and Cumulative Index to Nursing and Allied Health Literature were searched for published articles specific to the care of PWD provided in the ED. All English-language articles were reviewed; editorials and reflective journals were excluded. Seven articles ultimately met inclusion criteria; all provided Level 7 evidence: narrative review or opinions from authorities. The articles recommended clinical practices that can be categorized into five themes: assessment of cognitive impairment, dementia communication strategies, avoidance of adverse events, alterations to the physical environment, and education of ED staff. Many recommendations are extrapolated from residential care settings. Review results indicate that there is minimal guidance for the care of PWD specific to the ED setting. There are no empirical studies of the care (assessment, interventions) of PWD in the ED. The existing (Level 7) recommendations lack a research base to support their effectiveness or adoption as evidence-based practice. There is a significant opportunity for research to identify and test ways to meet the needs of PWD in the ED to ensure a safe visit, accurate diagnosis, and prudent transfer to the most appropriate level of care.

    ABSTRACT Background: The Brief Cognitive Status Exam (BCSE) is a new, optional subtest of the Wechsler Memory Scale-IV (WMS-IV) developed for rapid detection of cognitive deficits. We examined the clinical validation of the Dutch version of the BCSE in older adults with mild cognitive impairment (MCI) or dementia, comparing it to the Mini-Mental State Examination (MMSE). Method: BCSE and MMSE were administered in 39 older adults with MCI, 51 with dementia and 96 matched healthy controls. Results: Our results show that the BCSE is a valid screening instrument, with psychometric properties similar to the widely used MMSE. High correlations were found between the BCSE and MMSE (r = 0.79, n = 183, p < 0.001). Furthermore, a BCSE cut-off score ≤ 42 revealed a sensitivity of 96% a specificity of 92%, a positive predictive value of 86% and a negative predictive value of 97%, whereas the MMSE cut-off score of ≤ 24 showed values of 84%, 96%, 91%, and 92%, respectively. Sensitivity, specificity, positive and negative predictive values to detect MCI compared to controls was 81%, 80%, 61%, and 92%, respectively, on the BCSE, with a cut-off score of ≤ 46, and 84%, 76%, 57%, and 92%, respectively, on the MMSE, with a cut-off score of ≤ 27. Conclusions: The Dutch version of the BCSE is a clinically valid screening instrument for the detection of cognitive impairment in patients with dementia. Nevertheless, for distinguishing older adults with MCI from healthy controls both the BCSE and MMSE have limitations.

    Prevention and treatment of dementia has turned into a major public health challenge. Several epidemiological studies have indicated a significant association between the presence of hypertension and the onset of dementia (vascular or Alzheimer's type) several years later. Cognitive disorder may be related to focal cerebral lesions of vascular origin (infarctus, lacunae) and/or chronic ischemia of the white matter (white matter lesions) related to arteriosclerosis and/or lipohyalinosis of small perforating arteries high blood pressure in mid-life to later cognitive decline and dementia. Moreover, disorders of cerebral microcirculation and endothelial dysfunction may be associated to blood brain barrier dysfunction and amyloid plaques formation leading to Alzheimer's process. Few randomized clinical trials have included a cognitive assessment and dementia as outcome in their design. They all raise some major criticisms: cognitive assessment was never the main outcome, too short follow-up to study dementia; incomplete assessment of cognition, lost of follow-up and a small proportion of subjects at risk for dementia at inclusion. However, the results of therapeutic trials (SYST-EUR, PROGRESS) open the way to the prevention of dementia (vascular or Alzheimer's type) or cognitive decline by antihypertensive treatments. A meta-analysis including randomized controlled studies, suggests a significant decrease in the risk of dementia with antihypertensive treatment compared to placebo.

    Full Text Available Diagnostic accuracy in FDG-PET imaging highly depends on the operating procedures. In this clinical study on dementia, we compared the diagnostic accuracy at a single-subject level of a Clinical Scenarios, b Standard FDG Images and c Statistical Parametrical (SPM Maps generated via a new optimized SPM procedure. We evaluated the added value of FDG-PET, either Standard FDG Images or SPM Maps, to Clinical Scenarios. In 88 patients with neurodegenerative diseases (Alzheimer's Disease—AD, Frontotemporal Lobar Degeneration—FTLD, Dementia with Lewy bodies—DLB and Mild Cognitive Impairment—MCI, 9 neuroimaging experts made a forced diagnostic decision on the basis of the evaluation of the three types of information. There was also the possibility of a decision of normality on the FDG-PET images. The clinical diagnosis confirmed at a long-term follow-up was used as the gold standard. SPM Maps showed higher sensitivity and specificity (96% and 84%, and better diagnostic positive (6.8 and negative (0.05 likelihood ratios compared to Clinical Scenarios and Standard FDG Images. SPM Maps increased diagnostic accuracy for differential diagnosis (AD vs. FTD; beta 1.414, p = 0.019. The AUC of the ROC curve was 0.67 for SPM Maps, 0.57 for Clinical Scenarios and 0.50 for Standard FDG Images. In the MCI group, SPM Maps showed the highest predictive prognostic value (mean LOC = 2.46, by identifying either normal brain metabolism (exclusionary role or hypometabolic patterns typical of different neurodegenerative conditions.

  7. Identifying risk for dementia across populations: A study on the prevalence of dementia in tribal elderly population of Himalayan region in Northern India

    Full Text Available Introduction: Studies have suggested that dementia is differentially distributed across populations with a lower prevalence in developing regions than the developed ones. A comparison in the prevalence of dementia across populations may provide an insight into its risk factors. Keeping this in view, a study was planned to evaluate the prevalence of dementia in tribal elderly population. Materials and Methods: A cross-sectional comprehensive two-phase survey of all residents aged 60 years and older was conducted. Phase one involved screening of all individuals aged 60 and above with the help of a cognitive screen specifically developed for the tribal population. Phase two involved clinical examination of individuals who were suspected of dementia as per the developed cognitive screening test. Results: The results revealed that no individual above 60 years of age in the studied population was diagnosed as a case of dementia. Thereby, pointing out at some unknown factors, which are responsible for prevention of dementia. Discussion: The differences between the prevalence rate in this study and other studies in India appear to be a function of a valid regional difference. Environmental, phenotypic and genetic factors may contribute to regional and racial variations in dementia. Societies living in isolated hilly and tribal areas seem less predisposed to dementia, particularly age related neurodegenerative and vascular dementia, which are the most common causes for dementia in elderly. This may be because some environmental risk factors are much less prevalent in these settings.

    Full Text Available Objective: To determine whether learning and serial position effect (SPE differs qualitatively and quantitatively among different types of dementia and between dementia patients and controls; we also wished to find out whether interference affects it. Materials and Methods: We administered the Malayalam version of the Rey Auditory Verbal Learning Test (RAVLT to 30 cognitively unimpaired controls and 80 dementia patients [30 with Alzheimer′s disease (AD, 30 with vascular dementia (VaD, and 20 with frontotemporal dementia (FTD] with mild severity on the Clinical Dementia Rating Scale. Results: All groups were comparable on education and age, except the FTD group, who were younger. Qualitatively, the learning pattern and SPE (with primacy and recency being superior to intermediate was retained in the AD, VaD, and control groups. On SPE in free recall, recency was superior to intermediate in the FTD group (P < 0.01 using Bonferroni correction. On recognition, the AD and VaD groups had more misses (P < 0.01, while the FTD group had more false positives (P < 0.01. Conclusion: Quantitative learning is affected by dementia. The pattern of qualitative learning remains unaltered in dementia in the early stages.

    Hearing deficits associated with cognitive impairment have attracted much recent interest, motivated by emerging evidence that impaired hearing is a risk factor for cognitive decline. However, dementia and hearing impairment present immense challenges in their own right, and their intersection in the auditory brain remains poorly understood and difficult to assess. Here, we outline a clinically oriented, symptom-based approach to the assessment of hearing in dementias, informed by recent prog...

    Our objective was to compare the clinical and pathological characteristics of frontotemporal dementia patients with MAPT, GRN and C9orf72 gene mutations. We carried out a cross-sectional comparative study of 74 gene-positive patients (15 MAPT, 17 GRN and 42 C9orf72). Thirty had post mortem pathological data permitting clinico-pathological correlation. MAPT patients were younger than other groups, and showed more frequent behavioural disinhibition, repetitive and stereotyped behaviours, semantic impairment and temporal predominance of atrophy. GRN patients were older at death and more likely to present with non-fluent aphasia. C9orf72 patients alone showed a co-occurrence of ALS. They showed more psychotic symptoms and irrational behaviour, yet were more often reported clinically as socially appropriate and warm. They showed less dietary change than other groups. C9orf72 patients with and without ALS differed only in frequency of psychosis. Greater clinical overlap was observed between GRN and C9orf72 compared to MAPT cases. MAPT cases had tau and GRN and C9orf72, with one exception, TDP-43 pathology. Non-fluent aphasia was linked to TDP subtype A in both GRN and C9orf72 cases and ALS with subtype B. In conclusion, the findings reinforce clinical heterogeneity in FTD and strengthen evidence that genotype influences clinical presentation. Clinical features may inform targeted genetic testing.

    Cognitive and physical aspects of functionality are closely related. However, whether physical decline differs by dementia type and progression rate is debatable. To address these issues, we conducted a longitudinal study of 766 older adults whose physical performance and cognitive status were assessed annually with standard assessment tools [eg, Physical Performance Test, Clinical Dementia Rate (CDR)] for 8 years. Compared with participants who remained cognitively normal, those progressing to later-stage dementia (CDR=1) declined in their mobility by a factor of 2.82 (Pdementia (slope=-1.20, Pdementia (slope=-0.39, P=0.038) suggesting a steeper physical decline with dementia progression, particularly in those with the fastest disease progression. Although all types of dementia experienced mobility decline, those progressing to non-Alzheimer disease (AD) dementias, especially vascular dementia declined faster than those who remained normal (slope=-2.70, Pdementia patients particularly those with non-AD subtypes should be targeted for interventions to maintain or improve gait/balance and prevent functional decline and disability although AD patients may also benefit.

    Full Text Available Abstract The 7th International Symposium on Neuroprotection and Neurorepair was held from May 2nd to May 5th, 2012 in Potsdam, Germany. The symposium, which directly continues the successful Magdeburg meeting series, attracted over 330 colleagues from 29 countries to discuss recent findings and advances in the field. The focus of the 2012 symposium was widened from stroke and traumatic brain injury to neurodegenerative diseases, notably dementia, and more generally the ageing brain. Thereby, emphasis was given on neurovascular aspects of neurodegeneration and stroke including the blood–brain barrier, recent findings regarding the pathomechanism of Alzheimer’s disease, and brain imaging approaches. In addition, neurobiochemical aspects of neuroprotection, the role of astrogliosis, the clinical progress of cell-based approaches as well as translational hurdles and opportunities were discussed in-depth. This review summarizes some of the most stimulating discussions and reports from the meeting.

    2016-09-01

    Dementia is a frequent complication of Parkinson disease (PD) with a yearly incidence of around 10% of patients with PD. Lewy body pathology is the most important factor in the development of Parkinson disease dementia (PDD) and there is evidence for a synergistic effect with β-amyloid. The clinical phenotype in PDD extends beyond the dysexecutive syndrome that is often present in early PD and encompasses deficits in recognition memory, attention, and visual perception. Sleep disturbances, hallucinations, neuroleptic sensitivity, and fluctuations are often present. This review provides an update on current knowledge of PDD including aspects of epidemiology, pathology, clinical presentation, management, and prognosis.

    Full Text Available To further our understanding of the association between self-reported childhood learning disabilities (LDs and atypical dementia phenotypes (Atypical Dementia, including logopenic primary progressive aphasia (L-PPA, Posterior Cortical Atrophy (PCA, and Dysexecutive-type Alzheimer's Disease (AD.This retrospective case series analysis of 678 comprehensive neuropsychological assessments compared rates of self-reported LD between dementia patients diagnosed with Typical AD and those diagnosed with Atypical Dementia. 105 cases with neuroimaging or CSF data available and at least one neurology follow-up were identified as having been diagnosed by the neuropsychologist with any form of neurodegenerative dementia. These cases were subject to a consensus diagnostic process among three dementia experts using validated clinical criteria for AD and PPA. LD was considered Probable if two or more statements consistent with prior LD were documented within the Social & Developmental History of the initial neuropsychological evaluation.85 subjects (Typical AD n=68, Atypical AD n=17 were included in the final analysis.

    Recent evidence suggests that music-based interventions can be beneficial in maintaining cognitive, emotional, and social functioning in persons with dementia (PWDs). Our aim was to determine how clinical, demographic, and musical background factors influence the cognitive and emotional efficacy of caregiver-implemented musical activities in PWDs. In a randomized controlled trial, 89 PWD-caregiver dyads received a 10-week music coaching intervention involving either singing or music listening or standard care. Extensive neuropsychological testing and mood and quality of life (QoL) measures were performed before and after the intervention (n = 84) and six months later (n = 74). The potential effects of six key background variables (dementia etiology and severity, age, care situation, singing/instrument playing background) on the outcome of the intervention were assessed. Singing was beneficial especially in improving working memory in PWDs with mild dementia and in maintaining executive function and orientation in younger PWDs. Music listening was beneficial in supporting general cognition, working memory, and QoL especially in PWDs with moderate dementia not caused by Alzheimer's disease (AD) who were in institutional care. Both music interventions alleviated depression especially in PWDs with mild dementia and AD. The musical background of the PWD did not influence the efficacy of the music interventions. Our findings suggest that clinical and demographic factors can influence the cognitive and emotional efficacy of caregiver-implemented musical activities and are, therefore, recommended to take into account when applying and developing the intervention to achieve the greatest benefit.

    No drug to treat vascular dementia (VaD) has yet been approved by the American or European authorities, leaving a large population of patients without effective therapy. Cerebrolysin has a long record of safety and might be efficacious in this condition. We conducted a large, multicenter, double-blind, placebo-controlled study in 242 patients meeting the criteria for VaD. The primary endpoint was the combined outcome of cognition (based on Alzheimer's Disease Assessment Scale Cognitive Subpart, Extended Version [ADAS-cog+] score) and overall clinical functioning (based on Clinician's Interview-Based Impression of Change plus Caregiver Input [CIBIC+] score) assessed after 24 weeks of treatment. Intravenous Cerebrolysin 20 mL was administered once daily over the course of 2 treatment cycles as add-on therapy to basic treatment with acetylsalicylic acid. The addition of Cerebrolysin was associated with significant improvement in both primary parameters. At week 24, ADAS-cog+ score improved by 10.6 points in the Cerebrolysin group, compared with 4.4 points in the placebo group (least squares mean difference, -6.17; P Cerebrolysin group (ADAS-cog+ improvement of ≥4 points from baseline, 82.1% vs 52.2%; CIBIC+ score of Cerebrolysin, the odds ratio for achieving a favorable CIBIC+ response was 5.08 (P Cerebrolysin significantly improved clinical outcome, and that the benefits persisted for at least 24 weeks. Cerebrolysin was safe and well tolerated.

    In our study we analysed clinical and neuropsychological data in a cohort of 57 Sardinian patients with FTD (55 apparently unrelated and two belonging to the same family), who underwent genetic screening for the C9orf72 mutation. Eight out of 56 patients were found positive for the C9orf72 mutation representing 14% of the entire cohort and 31.6% of the familial cases (6/19). C9orf72 mutated patients differed from the other FTD cases of the cohort for a younger age of onset, higher frequency of familial history for FTD and higher prevalence of delusional psychotic symptoms and hallucinations. In the neuropsychological assessment, C9orf72 mutated patients differed from non-mutated for the high frequency of visuospatial dysfunction regarding constructional apraxia (p = 0.02). In conclusion, our study confirms that Sardinian FTD patients have peculiar genetic characteristics and that C9orf72 mutated patients have a distinctive clinical and neuropsychological profile that could help differentiate them from other FTD patients. In our cohort we found that constructional apraxia, rarely reported in FTD, can properly discriminate between C9orf72 mutated and non-mutated patients and contribute to broaden the neuropsychological profile in frontotemporal dementia associated with this mutation.

    Background Mild cognitive impairment (MCI) is a transitional state between normal ageing and dementia, at least for some patients. Behavioral symptoms in MCI are associated with a higher risk of dementia, but their association with dementia risk in patients without MCI is unknown. Mild Behavioral Impairment (MBI) refers to a late life syndrome with prominent psychiatric and related behavioral symptoms in the absence of prominent cognitive symptoms, which may also be a dementia prodrome. Objective To compare MCI and MBI patients and to estimate the risk of dementia development in these two groups. Method A consecutive series of 358 patients (239 with MCI; and 119 with MBI) presenting to an outpatient general hospital specialty clinic were followed for up to 5 years until conversion to dementia or censoring. Results 34% of MCI patients and over 70% of patients with MBI developed dementia (Logrank p=0.011). MBI patients without cognitive symptoms were more likely to develop dementia (Logrank p<0.001). MBI patients were more likely to develop dementia due to frontotemporal degeneration (FTD) as opposed to Alzheimer’s dementia (AD). Conclusion MBI appears to be a transitional state between normal ageing and dementia. MBI (specifically those without cognitive symptoms) may confer a higher risk for dementia than MCI and is likely an FTD prodrome in many cases. These findings have implications for the early detection, prevention, and treatment of patients with dementia in late life, by focusing on the emergence of new behavioral symptoms. PMID:19323967

    2001-01-01

    BACKGROUND—DNA ("did not attend") at outpatient clinics is an important problem costing the NHS an estimated £266 million annually. The national DNA rate for 1996-1997 for all clinics was 12%. The DNA rate at Hammersmith Hospital for the same year in the care of the elderly specialty was 21%. The aim of this study was to establish why this was so, and to test the efficacy of a reminder call in increasing attendance rates at care of the elderly clinics.
METHODS—23 DNAs from seven clinics were contacted to ascertain the reasons for non-attendance (group I). For seven further clinics, 84 patients were contacted in advance to reconfirm their appointment (group II).
RESULTS—From group II 12 patients were identified who were unaware of their appointment (14%), six of whom agreed to attend; thus six potential DNAs were prevented. Eleven vacant appointments were identified in advance. The unexpected DNA rate was reduced to 5% from a potential 21% as a result of this exercise. The DNA rate for all patients with dementia (both groups) was 44%, whereas the DNA rate for all patients without this diagnosis (both groups) was 16% (p < 0.001).
CONCLUSIONS—A preclinic phone call reminder to elderly patients is feasible, increases attendance rates, and identifies vacant appointments. Patients with dementia are more likely to miss clinic appointments; therefore they and their carers need specific reminders about appointment dates.

  4. Dementia worry and its relationship to dementia exposure, psychological factors, and subjective memory concerns.

    2016-01-01

    With increased societal awareness of dementia, older adults show increased concern about developing dementia, leading to misidentification of aging-related cognitive glitches as signs of dementia. While some researchers have suggested self-reported cognitive concerns accurately identify older adults with early signs of dementia, there is evidence that subjective cognitive decline is not associated with objective cognitive performance and instead reflects psychological factors consistent with models of health anxiety, including dementia worry. We examined the construct of dementia worry and its relationship to subjective memory concerns in 100 older adults (Mage = 69 years) without signs of dementia, using a recently developed measure of dementia worry. Consistent with hypotheses, dementia worry was related to exposure to dementia, having a high number of depressive or general worry symptoms, and having more memory concerns. Exposure to dementia moderated the relationship of dementia worry to depression and general worry. Furthermore, dementia worry moderated the relationship of objective memory impairment to subjective memory ratings. The results provide further evidence of the role of psychological factors such as dementia worry in subjective memory report and emphasize the need for objective cognitive testing before making determinations about dementia in older adults expressing memory concerns.

    The relative contributions of Alzheimer disease (AD) and vascular lesion burden to the occurrence of cognitive decline are more difficult to define in the oldest-old than they are in younger cohorts. To address this issue, we examined 93 prospectively documented autopsy cases from 90 to 103 years with various degrees of AD lesions, lacunes, and microvascular pathology. Cognitive assessment was performed prospectively using the Clinical Dementia Rating scale. Neuropathologic evaluation included the Braak neurofibrillary tangle (NFT) and β-amyloid (Aβ) protein deposition staging and bilateral semiquantitative assessment of vascular lesions. Statistics included regression models and receiver operating characteristic analyses. Braak NFTs, Aβ deposition, and cortical microinfarcts (CMIs) predicted 30% of Clinical Dementia Rating variability and 49% of the presence of dementia. Braak NFT and CMI thresholds yielded 0.82 sensitivity, 0.91 specificity, and 0.84 correct classification rates for dementia. Using these threshold values, we could distinguish 3 groups of demented cases and propose criteria for neuropathologic definition of mixed dementia, pure vascular dementia, and AD in very old age. Braak NFT staging and severity of CMI allow for defining most of demented cases in the oldest-old. Most importantly, single cutoff scores for these variables that could be used in the future to formulate neuropathologic criteria for mixed dementia in this age group were identified.

    The safety of Cerebrolysin has been shown through many years of clinical use, observations from postmarketing surveillance studies, and safety data from randomized, controlled clinical trials. The reported events showed that adverse reactions to Cerebrolysin were generally mild and transient. Most common adverse events included vertigo, agitation and feeling hot. In the controlled clinical trials analyzed for this report, the incidence of adverse events was similar in Cerebrolysin- and placebo-treated groups. Cerebrolysin seems to be safe when used in combination with recombinant tissue-type plasminogen activator or cholinesterase inhibitors such as donepezil or rivastigmine. To our knowledge, Cerebrolysin was not associated with major changes in vital signs or laboratory parameters.

    Objective: To assess the efficacy of Xianlong Capsule (XLC) in treating senile vascular dementia (VD). Methods: Forty-six patients of VD were randomly divided into two groups. The patients in XLC group (n=24) were treated with XLC and the patients in the control group (n=22) were treated with Hydergine. The therapeutic effect on dementia, TCM Syndrome, neurofunction deficit score, activities of daily living (ADL) score, Hasegawa Dementia Score (HDS) and mini-mental state examination (MMSE), etc. were examined and compared before and after treatment.Results: XLC could markedly increase MMSE scores and HDS of VD patients. It showed effect in ameliorating the TCM Syndromes and neurofunction deficit score significantly and could markedly improve the daily living activity of patients. The effect of XLC was better than that of Hydergine.Conclusion: XLC has definite effect in treating senile vascular dementia.

    Full Text Available Background: We investigated the demographic, clinical, and neuropsychological characteristics of frontotemporal dementia (FTD from the Clinical Research Center for Dementia of South Korea (CREDOS-FTD registry. Methods: A total of 200 consecutive patients with FTD recruited from 16 neurological clinics in Korea were evaluated by cognitive and functional assessments, a screening test for aphasia, behavioral questionnaires, motor assessments, and brain MRI or PET. Results: In our registry, 78 patients were classified as having been diagnosed with behavioral-variant FTD (bvFTD, 70 with semantic dementia (SD, 33 with progressive nonfluent aphasia (PNFA, and 8 with motor neuron disease plus syndrome (MND-plus. The patients with language variants of dementia were older than those with bvFTD. There were no differences in sex ratio, duration of illness, or level of education among the four subgroups. Overall, the patients with bvFTD showed a significantly better performance in cognitive tests. A higher frequency of motor symptoms and a lower frequency of behavioral symptoms were found in PNFA than in bvFTD and SD. The Global Language Index was significantly lower in SD than in bvFTD and PNFA. The MND-plus group had a poorer performance than all the others in all cognitive domains. Conclusion: The neuropsychological, behavioral, motor, and language characteristics of the four subtypes are comparable with those from other series. However, the proportion of SD (37.0%, which was similar to that of bvFTD (41.3%, was higher in our registry than in other series.

    Conclusions: This study underlines the need to consider and assess for psychotic symptoms in the frontotemporal dementia-amyotrophic lateral sclerosis continuum particularly in those with C9orf72 gene expansions. The network of brain regions identified in this study is strikingly similar to that identified in other psychotic disorders such as schizophrenia, which suggests that treatment strategies in psychiatry may be beneficial for the management of psychotic symptoms in frontotemporal dementia.

    Full Text Available Mahesh N Samtani, Nandini Raghavan, Gerald Novak, Partha Nandy, Vaibhav A Narayan On behalf of the Alzheimer’s disease Neuroimaging Initiative Janssen Research and Development, LLC, Raritan, New Jersey, USA Background: The objective of this analysis was to develop a nonlinear disease progression model, using an expanded set of covariates that captures the longitudinal Clinical Dementia Rating Scale–Sum of Boxes (CDR–SB scores. These were derived from the Alzheimer’s disease Neuroimaging Initiative ADNI-1 study, of 301 Alzheimer’s disease and mild cognitive impairment patients who were followed for 2–3 years. Methods: The model describes progression rate and baseline disease score as a function of covariates. The covariates that were tested fell into five groups: a hippocampal volume; b serum and cerebrospinal fluid (CSF biomarkers; c demographics and apolipoprotein Epsilon 4 (ApoE4 allele status; d baseline cognitive tests; and e disease state and comedications. Results: Covariates associated with baseline disease severity were disease state, hippocampal volume, and comedication use. Disease progression rate was influenced by baseline CSF biomarkers, Trail-Making Test part A score, delayed logical memory test score, and current level of impairment as measured by CDR–SB. The rate of disease progression was dependent on disease severity, with intermediate scores around the inflection point score of 10 exhibiting high disease progression rate. The CDR–SB disease progression rate in a typical patient, with late mild cognitive impairment and mild Alzheimer’s disease, was estimated to be approximately 0.5 and 1.4 points/year, respectively. Conclusions: In conclusion, this model describes disease progression in terms of CDR–SB changes in patients and its dependency on novel covariates. The CSF biomarkers included in the model discriminate mild cognitive impairment subjects as progressors and nonprogressors. Therefore, the model may

    Full Text Available Background: We have previously reported the prevalence of dementia in older adults living in the rural Hai district of Tanzania according to the Diagnostic and Statistical Manual of Mental Disorders, 4th edition (DSM-IV criteria. The aim of this study was to compare prevalence rates using the DSM-IV criteria with those obtained using the 10/66 diagnostic criteria, which is specifically designed for use in low- and middle-income countries. Methods: In phase I, 1,198 people aged 70 and older were screened for dementia. A stratified sample of 296 was then clinically assessed for dementia according to the DSM-IV criteria. In addition, data were collected according to the protocol of the 10/66 Dementia Research Group, which allowed a separate diagnosis of dementia according to these criteria to be established. Results: The age-standardised prevalence of clinical DSM-IV dementia was 6.4% (95% confidence interval [CI] 4.9–7.9% and of ‘10/66 dementia’ was 21.6% (95% CI 17.5–25.7%. Education was a significant predictor of ‘10/66 dementia’, but not of DSM-IV dementia. Conclusions: There are large discrepancies in dementia prevalence rates depending on which diagnostic system is used. In rural sub-Saharan Africa, it is not clear whether the association between education and dementia using the 10/66 criteria is a genuine effect or the result of an educational bias within the diagnostic instrument. Despite its possible flaws, the DSM-IV criteria represent an international standard for dementia diagnosis. The 10/66 diagnostic criteria may be more appropriate when identification of early and mild cognitive impairment is required.

  15. Neurobiology of Vascular Dementia

    Full Text Available Vascular dementia is, in its current conceptual form, a distinct type of dementia with a spectrum of specific clinical and pathophysiological features. However, in a very large majority of cases, these alterations occur in an already aged brain, characterized by a milieu of cellular and molecular events common for different neurodegenerative diseases. The cell signaling defects and molecular dyshomeostasis might lead to neuronal malfunction prior to the death of neurons and the alteration of neuronal networks. In the present paper, we explore some of the molecular mechanisms underlying brain malfunction triggered by cerebrovascular disease and risk factors. We suggest that, in the age of genetic investigation and molecular diagnosis, the concept of vascular dementia needs a new approach.

    Spouse caregivers of people with dementia (PwD) report relatively poor marital relationship quality (RQ), but few studies have obtained the perspective of the PwD, examined discrepancies between spouses, or considered changes in RQ over time. This study explored caregiver and PwD perceptions of RQ, identified associated factors, and examined changes over an 18-month period. Participants were 54 couples where one spouse had early-stage dementia and 54 were control couples. RQ was assessed with the Positive Affect Index. Measures of mood, stress, and quality of life (QoL) were also administered. The clinical couples were followed up after 9 and 18 months. Caregivers gave significantly lower RQ ratings than controls. PwD ratings did not differ significantly from those of caregivers or controls. Dyadic discrepancies were significantly greater in the clinical than in the control group. Caregiver ratings were associated with stress, whereas PwD ratings were associated with depression and QoL. Discrepancies were associated with caregiver stress and with PwD mood, QoL, and age. Caregiver ratings declined significantly over time; PwD ratings did not decline significantly, but showed different trends for men and women. It is important to consider RQ when considering how to support couples where one partner has early-stage dementia.

    Against a background of an ever-increasing number of patients, new management options, and novel imaging modalities, neuroimaging is playing an increasingly important role in the diagnosis of dementia. This up-to-date, superbly illustrated book aims to provide a practical guide to the effective use of neuroimaging in the patient with cognitive decline. It sets out the key clinical and imaging features of the wide range of causes of dementia and directs the reader from clinical presentation to neuroimaging and on to an accurate diagnosis whenever possible. After an introductory chapter on the clinical background, the available ''toolbox'' of structural and functional neuroimaging techniques is reviewed in detail, including CT, MRI and advanced MR techniques, SPECT and PET, and image analysis methods. The imaging findings in normal ageing are then discussed, followed by a series of chapters that carefully present and analyze the key imaging findings in patients with dementias. A structured path of analysis follows the main presenting feature: disorders associated with primary gray matter loss, with white matter changes, with brain swelling, etc. Throughout, a practical approach is adopted, geared specifically to the needs of clinicians (neurologists, radiologists, psychiatrists, geriatricians) working in the field of dementia, for whom this book should prove an invaluable resource.

    Background Recent reports have suggested declining age-specific incidence rates of dementia in high-income countries over time. Improved education and cardiovascular health in early age have been suggested to be bringing about this effect. The aim of this study was to estimate the age-specific dementia incidence trend in primary care records from a large population in the Netherlands. Methods and findings A dynamic cohort representative of the Dutch population was composed using primary care records from general practice registration networks (GPRNs) across the country. Data regarding dementia incidence were obtained using general-practitioner-recorded diagnosis of dementia within the electronic health records. Age-specific dementia incidence rates were calculated for all persons aged 60 y and over; negative binomial regression analysis was used to estimate the time trend. Nine out of eleven GPRNs provided data on more than 800,000 older people for the years 1992 to 2014, corresponding to over 4 million person-years and 23,186 incident dementia cases. The annual growth in dementia incidence rate was estimated to be 2.1% (95% CI 0.5% to 3.8%), and incidence rates were 1.08 (95% CI 1.04 to 1.13) times higher for women compared to men. Despite their relatively low numbers of person-years, the highest age groups contributed most to the increasing trend. There was no significant overall change in incidence rates since the start of a national dementia program in 2003 (−0.025; 95% CI −0.062 to 0.011). Increased awareness of dementia by patients and doctors in more recent years may have influenced dementia diagnosis by general practitioners in electronic health records, and needs to be taken into account when interpreting the data. Conclusions Within the clinical records of a large, representative sample of the Dutch population, we found no evidence for a declining incidence trend of dementia in the Netherlands. This could indicate true stability in incidence rates, or

    Dementia--a syndrome of acquired intellectual deterioration--is an etiologically non-specific condition which is permanent, progressive, or reversible. In the evaluation of demented patients, a careful exposure history will determine the possible role of drugs, metals, or toxins. The physical examination may reveal focal deficits in cases of intracranial mass lesions and spasticity or ataxia of the lower limbs if hydrocephalus is present. Coexistance of dementia and peripheral neuropathy usually indicates a toxic or metabolic disorder. Asterixis, myoclonus, and postural tremor are common in toxic-metabolic dementias, while resting tremor, choreoathetosis, and rigidity occur in progressive extrapyramidal disorders. EEG is focally abnormal in cases of cerebral mass lesions and exhibits generalized slowing in toxic-metabolic encephalopathies. CT will aid in the identification of hydrocephalus, subdural hematomas, and intracranial mass lesions. A thorough laboratory evaluation including complete blood count, erythrocyte sedimentation rate, electrolytes, blood urea nitrogen and blood sugar, liver and thyroid tests, calcium and phosphorus levels, B12 and folate levels, serum copper and ceruloplasmin, VDRL, chest X-ray, electrocardiogram, and lumbar puncture may demonstrate treatable disorders that are adversely affecting intellectual function. Elderly individuals are particularly susceptible to the effects of toxic or metabolic disorders, and a mild dementia might be exaggerated by relatively minor fluctuations in metabolic status. Treatable causes of dementia should be considered in all demented patients.

    Errorless learning (EL) is an instructional procedure involving error reduction during learning. Errorless learning is mostly examined by counting correctly executed task steps or by rating them using a Task Performance Scale (TPS). Here, we explore the validity and reliability of a new assessment procedure, the core elements method (CEM), which rates essential building blocks of activities rather than individual steps. Task performance was assessed in 35 patients with Alzheimer's dementia recruited from the Relearning methods on Daily Living task performance of persons with Dementia (REDALI-DEM) study using TPS and CEM independently. Results showed excellent interrater reliabilities for both measure methods (CEM: intraclass coefficient [ICC] = .85; TPS: ICC = .97). Also, both methods showed a high agreement (CEM: mean of measurement difference [MD] = -3.44, standard deviation [SD] = 14.72; TPS: MD = -0.41, SD = 7.89) and correlated highly (>.75). Based on these results, TPS and CEM are both valid for assessing task performance. However, since TPS is more complicated and time consuming, CEM may be the preferred method for future research projects.

    The objective was to summarize recent findings about the clinical features, diagnosis and investigation of dementia with Lewy (DLB) bodies, together with its neuropathology, neurochemistry and genetics. Dementia with Lewy bodies (DLB) is a primary, neurodegenerative dementia sharing clinical and pathological characteristics with both Parkinson's disease (PD) and Alzheimer's disease (AD). Antiubiquitin immunocytochemical staining, developed in the early 1990s, allowed the frequency and distribution of cortical LBs to be defined. More recently, alpha-synuclein antibodies have revealed extensive neuritic pathology in DLB demonstrating a neurobiological link with other "synucleinopathies" including PD and multiple system atrophy (MSA). The most significant correlates of cognitive failure in DLB appear to be with cortical LB and Lewy neurites (LNs) rather than Alzheimer type pathology. Clinical diagnostic criteria for DLB, published in 1996, have been subjected to several validation studies against autopsy findings. These conclude that although diagnostic specificity is high (range 79- 100%, mean 92%), sensitivity is lower (range 0- 83 %, mean, 49%). Improved methods of case detection are therefore required. Fluctuating impairments in attention, visual recognition and construction are more indicative of DLB than AD. Relative preservation of medial temporal lobe volume on structural MRI and the use of SPECT tracers for regional blood flow and the dopamine transporter are the most reliable current biomarkers for DLB. There are no genetic or CSF tests recommended for the diagnosis of DLB at present. Between 15 and 20% of all elderly demented cases reaching autopsy have DLB, making it the most common cause of degenerative dementia after AD. Exquisite, not infrequently fatal, sensitivity to neuroleptic drugs and encouraging reports of the effects of cholinesterase inhibitors on cognitive, psychiatric and neurological features, mean that an accurate diagnosis of DLB is more

    The population of oldest old, or people aged 85 and older, is growing rapidly. A better understanding of dementia in this population is thus of increasing national and global importance. In this review, we describe the major epidemiological studies, prevalence, clinical presentation, neuropathological and imaging features, risk factors, and treatment of dementia in the oldest old. Prevalence estimates for dementia among those aged 85+ ranges from 18 to 38%. The most common clinical syndromes are Alzheimer's dementia, vascular dementia, and mixed dementia from multiple etiologies. The rate of progression appears to be slower than in the younger old. Single neuropathological entities such as Alzheimer's dementia and Lewy body pathology appear to have declining relevance to cognitive decline, while mixed pathology with Alzheimer's disease, vascular disease (especially cortical microinfarcts), and hippocampal sclerosis appear to have increasing relevance. Neuroimaging data are sparse. Risk factors for dementia in the oldest old include a low level of education, poor mid-life general health, low level of physical activity, depression, and delirium, whereas apolipoprotein E genotype, late-life hypertension, hyperlipidemia, and elevated peripheral inflammatory markers appear to have less relevance. Treatment approaches require further study, but the oldest old may be more prone to negative side effects compared with younger patients and targeted therapies may be less efficacious since single pathologies are less frequent. We also highlight the limitations and challenges of research in this area, including the difficulty of defining functional decline, a necessary component for a dementia diagnosis, the lack of normative neuropsychological data, and other shortcomings inherent in existing diagnostic criteria. In summary, our understanding of dementia in the oldest old has advanced dramatically in recent years, but more research is needed, particularly among varied racial

    Anxiety is common in dementia and is associated with decreased independence and increased risk of nursing home placement. However, little is known about the treatment of anxiety in dementia. This article reports results from two patients who were treated with a modified version of cognitive-behavioral therapy for anxiety in dementia (CBT-AD). Modifications were made in the content, structure, and learning strategies of CBT to adapt skills to the cognitive limitations of these patients and include collaterals (i.e., family members, friends, or other caregivers) in the treatment process. The patients received education and awareness training and were taught the skills of diaphragmatic breathing, coping self-statements, exposure, and behavioral activation. The Clinical Dementia Rating (CDR) Scale was used to characterize dementia severity and determine eligibility for treatment (a CDR score of 0.5 to 2.0 was required for participation). Other measures included the Rating Anxiety in Dementia scale, the Neuropsychiatric Inventory Anxiety subscale, and the Mini International Neuropsychiatric Interview. Outcome data showed improvement in anxiety as measured by standardized rating scales. We conclude that CBT-AD is potentially useful in treating anxiety in dementia patients and that this technique merits further study.

    Frontotemporal dementia (FTD) is a clinical phenotype of dementia, characterized by complex of clinical symptoms, including disinhibition, character change, increased appetite, sexual misconduct and language problems. Frontotemporal lobar degeneration (FTLD) is a pathological classification of neurodegenerative disorder and its core consists of Pick's disease (PiD). Historically, PiD was morphologically subclassified into three types, but recent immunocytochemical investigations defined type I as PiD with Pick bodies (three repeat tauopathy), type II as corticobasal degeneration (CBD, four repeat tauopathy) and type III as FTLD with ubiquitinated inclusions (FTLD-U). The recent progress provided an evidence that the majority of FTLD-U represented primary TDP 43 proteionopathy. Three major clinical phenotypes of FTLD consist of FTD, semantic dementia (SD) and progressive non-fluent aphasia (PNFA). Clinical and pathological correlative studies demonstrated that majority of the background pathology of FTD is PiD with Pick bodies, that of SD is FTLD-U and that of PNFA is CBD, although there are too many exceptions. Although FTD is one of the major clinical manifestations of FTLD, the most frequent pathological background of FTD is Alzheimer disease (AD). The degenerative processes causing FTD symptoms include dementia with Lewy bodies (DLB), progressive supranuclear palsy (PSP) and argyrophilic grain disease. Moreover, vascular process such as Binswanger disease and inflammatory process such as neurosyphilis could also present with FTD symptoms. Since FTD requires special clinical care distinct from AD, clinical diagnosis of FTD is quite important. But for the fundamental treatment based on background pathological processes, surrogate biomarkers, including structural and functional neuroimages and findings of cerebrospinal fluid, blood and urine, should be pursued for future progress in FTD research.

    We investigated the prevalence of dementia and mild cognitive impairment (MCI) and the factors associate with risk of dementia from a representative nationwide sample of Korean elders. 8,199 randomly-sampled Koreans aged 65 years or older were invited to participate in the Phase I screening assessment using Mini-Mental State Examination by door-to-door home visit, and 6,141 subjects (response rate = 74.9%) responded. Among them, 2,336 subjects were invited to participate in the Phase II diagnostic assessment for dementia and MCI, and 1,673 subjects responded (response rate = 71.6%). Diagnostic assessments were administered using the Korean version of the Consortium to Establish a Registry for Alzheimer's Disease Assessment Packet (CERAD-K) Clinical Assessment Battery. The CERAD-K Neuropsychological Assessment Battery was used for diagnosing MCI. Age-, gender-, education-, and urbanicity-standardized prevalence of dementia was estimated to be 8.1% (95% CI = 6.9-9.2) for overall dementia and 24.1% (95% CI = 21.0-27.2) for MCI. Alzheimer's disease (AD) was the most prevalent type (5.7%) followed by vascular dementia (2.0%). Amnestic subtype (20.1%) was much more prevalent than nonamnestic subtype in MCI (4.0%). Older age, being male, lower education level, illiteracy, smoking, and histories of head trauma or depression were associated with increased dementia risk, and alcohol use and moderately intense exercise were associated with decreased dementia risk. We expect numbers of dementia patients to double every 20 years until 2050 in Korea and expect AD to account for progressively more dementia cases in the future.

    We report a case of a 46-year-old man presenting with a progressive cognitive decline, ataxic gait, urinary incontinence for 4 months and neuroimaging consistent with normal pressure hydrocephalus. The atypical presentation of a progressively worsening dysphasia and a right hemiparesis dismissed as a vascular event 1 month earlier associated with normal pressure hydrocephalus prompted further investigations confirming neurosyphilis also manifesting as dementia paralytica. Treatment using consensus guidelines led to resumption of activities of daily living. Neurosyphilis, considered rare in the neuroimaging era, must still be considered a reversible cause of dementia and other neurological manifestations in contemporary neurological practice.

    Full Text Available Previous publications have shown a high diagnostic sensitivity and specificity of three short clinical rating scales for Alzheimer's disease (AD, frontotemporal dementia (FTD, and vascular dementia (VaD validated against neuropathological (NP diagnoses. In this study, the aim was to perform an exploratory factor analysis of the items in these clinical rating scales. The study included 190 patients with postmortem diagnoses of AD (n=74, VaD (n=33, mixed AD/VaD (n=31, or FTD (n=52. The factor analysis produced three strong factors. Factor 1 contained items describing cerebrovascular disease, similar to the Hachinski Ischemic Score. Factor 2 enclosed major clinical characteristics of FTD, and factor 3 showed a striking similarity to the AD scale. A fourth symptom cluster was described by perception and expression of emotions. The factor analyses strongly support the construct validity of the diagnostic rating scales.

    Outpatient dementia healthcare is predominantly fragmented, and dementia networks (DNs) represent an integrated care concept to overcome this problem. Little is known about the patients of these networks with regard to utilisation of physicians and associated factors. We interviewed 560 caregivers of people with dementia in 13 different DNs in Germany in 2013 and assessed socio-demographics, clinical data and physician utilisation. Networks were categorised in predominantly medical DNs and community-oriented DNs. Descriptive and multivariate statistical models were used to identify associated factors between DNs and users' data. Overall, the users of networks received high rates of physician care; 93% of the sample stated at least one contact with a primary care physician within the last 6 months, and 74% had been treated by a specialist (neurology/psychiatry physician). Only 5% of the sample had no contact with a physician in the 6 months preceding the interview. Females showed a lower odds for physician specialist consultations (OR = 0.641). Users of medical DNs receive greater specialist consultations overall (OR = 8.370). Compared to the German general population and people with dementia in other settings, users of DNs receive physician care more regularly, especially with regard to the consultations of neurologist/psychiatrists. Therefore, DNs seem to perform a supportive role within the integration of physician healthcare. More research is needed on the appropriate relationship between the needs of the people with dementia and utilisation behaviour.

    Many European countries test cars, but not their drivers, as they age. There is evidence to suggest that human factors are more important than vehicular factors as causes of motor crashes. The elderly also are involved in more accidents per distance travelled than middle-aged drivers. As the UK relies on self-certification of health by drivers over the age of 70 years, we examined the driving practices of patients with dementia attending a Memory Clinic. Nearly one-fifth of 329 patients with documented dementia continued to drive after the onset of dementia, and impaired driving ability was noted in two-thirds of these. Their families experienced great difficulty in persuading patients to stop driving, and had to invoke outside help in many cases. Neuropsychological tests did not help to identify those who drove badly while activity of daily living scores were related to driving ability. These findings suggest that many patients with dementia drive in an unsafe fashion after the onset of the illness. The present system of self-certification of health by the elderly for driver-licensing purposes needs to be reassessed.

  1. The relationship between cognitive impairment and in vivo metabolite ratios in patients with clinical Alzheimer's disease and vascular dementia: a proton magnetic resonance spectroscopy study

    Previous magnetic resonance spectroscopy (MRS) studies have shown increased myo-inositol (MI) and decreased N-acetyl aspartate (NAA) levels in the parieto-occipital lobes of patients with Alzheimer's disease (AD) compared to those with other dementias and normal subjects. This study aimed to establish the quantitative relationship between metabolite ratios and degree of cognitive impairment in patients with mild to moderate AD and sub-cortical ischaemic vascular dementia (SIVD). Forty-four older people with clinical dementia were recruited from a memory clinic and followed up for 2.0-3.5 years; 20 cases were finally classified as probable AD, 18 as SIVD and 6 as mixed type. Mini Mental State Examination (MMSE) and short echo time single voxel automated MRS from the mesial parieto-occipital lobes were performed at the time of initial referral. Spearman rank correlation coefficients were calculated for MMSE scores and measured metabolite ratios MI/Cr, NAA/Cr, Cho/Cr and NAA/MI. The AD group showed a significant correlation between MMSE and NAA/MI (r=0.54, P=0.014) and NAA/Cr (r=0.48, P=0.033), and a negative, non-significant association with MI/Cr (r=-0.41, P=0.072). MI/Cr was negatively correlated with NAA/Cr (r=-0.51, P=0.021). Neither Cho/Cr ratios nor age correlated with cognitive function. The SIVD group showed no correlation between any of the measured metabolite ratios and MMSE score. This study reinforces the specific association between reduced NAA and increased MI levels in the parieto-occipital region and cognitive impairment in AD. MRS may have a role in evaluating disease progression and therapeutic monitoring in AD, as new treatments become available. (orig.)

    2012-03-01

    In 2010, approximately 500,000 Canadians suffered from a dementia-related illness. The number of sufferers is estimated to double in about 25 years. Due to this growing demographic, dementia (most frequently caused by Alzheimer's disease) will increasingly have a significant impact on our aging community and their caregivers. Dementia is associated with challenging behaviours such as agitation, wandering, and aggression. Care providers must find innovative strategies that facilitate the quality of life for this population; moreover, such strategies must value the individual person. Social commitment robots - designed specifically with communication and therapeutic purposes - provide one means towards attaining this goal. This paper describes a study in which Paro (a robotic baby harp seal) was used as part of a summer training program for students. Preliminary conclusions suggest that the integration of social commitment robots may be clinically valuable for older, agitated persons living with dementia in long-term care settings.

    Nutritional status may be a modifiable factor in the progression of dementia. We examined the association of nutritional status and rate of cognitive and functional decline in a U.S. population-based sample. Study design was an observational longitudinal study with annual follow-ups up to 6 years of 292 persons with dementia (72% Alzheimer's disease, 56% female) in Cache County, UT using the Mini-Mental State Exam (MMSE), Clinical Dementia Rating Sum of Boxes (CDR-sb), and modified Mini Nutritional Assessment (mMNA). mMNA scores declined by approximately 0.50 points/year, suggesting increasing risk for malnutrition. Lower mMNA score predicted faster rate of decline on the MMSE at earlier follow-up times, but slower decline at later follow-up times, whereas higher mMNA scores had the opposite pattern (mMNA by time β= 0.22, p = 0.017; mMNA by time2 β= -0.04, p = 0.04). Lower mMNA score was associated with greater impairment on the CDR-sb over the course of dementia (β= 0.35, p <  0.001). Assessment of malnutrition may be useful in predicting rates of progression in dementia and may provide a target for clinical intervention.

    2011-01-01

    Introduction. The purpose of this study was to examine the success rate and find factors affecting the clinical success of microimplants used as orthodontic anchorage. Methods. Seventy-three consecutive patients (25 male, 48 female; mean age, 22.45 years) with a total of 139 screw implants of 2 types were examined. Success rate was determined according to 18 clinical variables. Results. The overall success rate was 87.8%. The clinical variables of microimplant factors (type), patient factors (sex, skeletal and dental relationships, overbite, jaw involved, side involved and site involved), and treatment factors (type of insertion, time of loading, purpose of microimplant insertion, mode of loading, type of anchorage used, direction of forces applied) did not show any statistical difference in success rates. Mandibular angle, vertical position of implant placement, oral hygiene status, and inflammation showed significant difference in success rates. Conclusions. Proper case selection and following the recommended protocol are extremely essential to minimise failures.

  7. Assessment of neuropsychiatric symptoms in dementia: Toward improving accuracy

    Directory of Open Access Journals (Sweden)

    Florindo Stella

    Full Text Available ABSTRACT The issue of this article concerned the discussion about tools frequently used tools for assessing neuropsychiatric symptoms of patients with dementia, particularly Alzheimer's disease. The aims were to discuss the main tools for evaluating behavioral disturbances, and particularly the accuracy of the Neuropsychiatric Inventory - Clinician Rating Scale (NPI-C. The clinical approach to and diagnosis of neuropsychiatric syndromes in dementia require suitable accuracy. Advances in the recognition and early accurate diagnosis of psychopathological symptoms help guide appropriate pharmacological and non-pharmacological interventions. In addition, recommended standardized and validated measurements contribute to both scientific research and clinical practice. Emotional distress, caregiver burden, and cognitive impairment often experienced by elderly caregivers, may affect the quality of caregiver reports. The clinician rating approach helps attenuate these misinterpretations. In this scenario, the NPI-C is a promising and versatile tool for assessing neuropsychiatric syndromes in dementia, offering good accuracy and high reliability, mainly based on the diagnostic impression of the clinician. This tool can provide both strategies: a comprehensive assessment of neuropsychiatric symptoms in dementia or the investigation of specific psychopathological syndromes such as agitation, depression, anxiety, apathy, sleep disorders, and aberrant motor disorders, among others.

    2017-01-01

    Pain is still a neglected clinical issue in elderly people with dementia and/or communicative disorders, with an unacceptable higher rate of under diagnosis and under treatment. Cognitive deficit and emotional and psychological disturbances entangle pain symptoms, affecting patient self-report. So far, observational pain tools do not have fully adequate clinimetric properties and quality requirements for easy-to-use daily rating. Older patients with dementia represent a clinical challenge. The assessment of pain is important for improving clinical outcomes, such as functional status, frailty trajectories, comorbidity, and quality of life. The PAINAID scale appears to be the most accurate pain tool in people with dementia along with the Algoplus® scale, a recently developed tool to rapidly assess acute pain in hospitals settings. The present study aimed to assess the clinimetric properties of the Algoplus®, as compared to PAINAID, for detecting acute pain in a real-world cohort of hospitalized older patients with dementia.

  19. Sleep, Cognition and Dementia.

    Science.gov (United States)

    Porter, Verna R; Buxton, William G; Avidan, Alon Y

    2015-12-01

    The older patient population is growing rapidly around the world and in the USA. Almost half of seniors over age 65 who live at home are dissatisfied with their sleep, and nearly two-thirds of those residing in nursing home facilities suffer from sleep disorders. Chronic and pervasive sleep complaints and disturbances are frequently associated with excessive daytime sleepiness and may result in impaired cognition, diminished intellect, poor memory, confusion, and psychomotor retardation all of which may be misinterpreted as dementia. The key sleep disorders impacting patients with dementia include insomnia, hypersomnolence, circadian rhythm misalignment, sleep disordered breathing, motor disturbances of sleep such as periodic leg movement disorder of sleep and restless leg syndrome, and parasomnias, mostly in the form of rapid eye movement (REM) sleep behavior disorder (RBD). RBD is a pre-clinical marker for a class of neurodegenerative diseases, the "synucleinopathies", and requires formal polysomnographic evaluation. Untreated sleep disorders may exacerbate cognitive and behavioral symptoms in patients with dementia and are a source of considerable stress for bed partners and family members. When left untreated, sleep disturbances may also increase the risk of injury at night, compromise health-related quality of life, and precipitate and accelerate social and economic burdens for caregivers.

  20. Diagnosing young onset dementia can be challenging.

    Ahmed, Samrah; Baker, Ian; Butler, Christopher R

    2016-05-01

    Although the risk of developing dementia increases with age, onset can be as early as the third or fourth decade of life. Genetic influences play a more important role in younger than in older people with dementia, so young onset dementia may cluster in families. Diagnosing young onset dementia is challenging. The range of possible presenting features is broad, encompassing behavioural, cognitive, psychiatric and neurological domains, and symptoms are often subtle initially. Frequently the complaints are misattributed to stress or depression, and the patient is falsely reassured that they are too young to have dementia. The most common causes of young onset dementia are early onset forms of adult neurodegenerative conditions and alcohol. Vascular dementia is the second most common cause of young onset dementia after Alzheimer's disease. Conventional vascular risk factors may be absent and diagnosis relies on imaging evidence of cerebrovascular disease. Obtaining a detailed history remains the most important part of the workup and usually requires corroboration by a third party. Undertaking a basic neurological examination is also important. Those with suspected young onset dementia should be referred to a neurology-led cognitive disorders clinic where available as the differenti diagnosis is considerably broader tha in older adults and requires specialist investigation.

    A hexanucleotide repeat expansion in the first intron of C9ORF72 has been shown to be responsible for a high number of familial cases of amyotrophic lateral sclerosis or frontotemporal lobar degeneration with or without concomitant motor neuron disease phenotype and TDP-43 based pathology. Here, we report on three cases carrying the hexanucleotide repeat expansion with an atypical presentation consisting in the development of psychiatric symptoms. Patient #1, a 53 year old man with positive family history for dementia, presented with mood deflection, characterized by apathy, social withdraw, and irritability in the last two years. He was diagnosed with "mild cognitive impairment due to depressive syndrome" six months later and subsequently with Alzheimer's disease. Patient #2, a woman with positive family history for dementia, developed behavioral disturbances, aggressiveness, and swearing at 57 years of age. Patient #3 presented, in the absence of brain atrophy, with mystical delirium with auditory hallucinations at 44 years of age, and did not present neurological symptoms over a 7-year follow up. The description of these cases underlines that the hexanucleotide repeat expansion in chromosome 9 could be associated with early onset psychiatric presentations.

    Previous studies have highlighted that decreased hippocampal volume, an early neural correlate of dementia, is commonly observed in patients with mild cognitive impairment (MCI). However, it is unclear whether neurodegenerative and resultant clinical trajectories are accelerated in MCI patients with concomitant depressive symptoms, leading to a faster conversion to dementia stages than those who are not depressed. No longitudinal study has investigated whether depressed amnestic MCI (DEP+aMCI) patients show an earlier onset of progression to dementia than non-depressed amnestic MCI (DEP-aMCI) patients and whether progressive hippocampal volume reductions are related in the conversion process. Using data from Alzheimer's Disease Neuroimaging Initiative, we examined 2-year follow-up data from 38 DEP+aMCI patients and 38 matched DEP-aMCI patients and compared their ages of conversion from aMCI to AD and trajectories of progressive hippocampal volume changes. DEP+ and DEP- patients were defined as having baseline Geriatric Depression Scale scores of 5 or above and 0, respectively. DEP+ converters showed earlier ages of conversion to dementia (p = 0.009) and greater left hippocampal volume loss than both DEP- converters and DEP+ non-converters over the 2-year period (p = 0.003, p = 0.001, respectively). These findings could not be explained by changes in total brain volume, differences in their clinical symptoms of dementia, daily functioning, or apolipoprotein E4 genotypes. No difference in conversion rate to dementia or progressive hippocampal volume change was found between DEP+ patients and DEP-patients, which suggested depressive symptoms themselves may not lead to progression of dementia from MCI. In conclusion, there is a synergistic effect of depressive symptoms and smaller left hippocampal volume in MCI patients that accelerates conversion to dementia.

    Dementia is a complex clinical condition characterized by several cognitive impairments that interfere with patient independence in executing everyday tasks. Various neurodegenerative disorders have dementia in common among their clinical manifestations. In addition, these diseases, such as Alzheimer's disease, Parkinson's disease, dementia with Lewy bodies and frontotemporal dementia, share molecular alterations at the neuropathological level. In recent years, the field of neuroepigenetics has expanded massively and it is now clear that epigenetic processes, such as DNA methylation, are mechanisms involved in both normal and pathological brain function. Despite the persistent methodological and conceptual caveats, it has been reported that several genes fundamental to the development of neurodegenerative disorders are deregulated by aberrant methylation patterns of their promoters, and even common epigenetic signatures for some dementia-associated pathologies have been identified. Therefore, understanding the epigenetic mechanisms that are altered in dementia, especially those associated with the initial phases, will allow us not only to understand the etiopathology of dementia and its progression but also to design effective therapies to reduce this global public health problem. This review provides an in-depth summary of our current knowledge about DNA methylation in dementia, focusing exclusively on the analyses performed in human brain.Molecular Psychiatry advance online publication, 3 January 2017; doi:10.1038/mp.2016.242.

    Full Text Available The association between primary headaches, including tension-type headache (TTH as one of the most common primary headache disorders, and dementia remains controversial. In this nationwide, population-based, retrospective, cohort study, we explored the potential association between TTH and dementia and examined sex, age, and comorbidities as risk factors for dementia.Using the Taiwan National Health Insurance Research Database (NHIRD claims data, the sample included 13908 subjects aged ≥20 years with newly-diagnosed TTH in 2000-2006. The non-TTH group included 55632 randomly selected sex- and age-matched TTH-free individuals. All subjects were followed until dementia diagnosis, death, or the end of 2011. Patients with dementia, including vascular and non-vascular (including Alzheimer's subtypes, were identified using International Classification of Diseases Ninth Revision, Clinical Modification codes. Multivariate Cox proportional hazards regression models were used to assess the risk of dementia and dementia-associated risk factors, such as migraine and other medical comorbidities.During the average follow-up of 8.14 years, the incidence density rates of dementia were 5.30 and 3.68/1,000 person-years in the TTH and non-TTH groups, respectively. Compared with the non-TTH group, the risks of dementia were 1.25 (95% confidence interval [CI], 1.11-1.42 and 1.13 (95% CI, 1.01-1.27 times higher in the women and >65-year-old TTH group, respectively. TTH patients with comorbidities had a higher risk of dementia. TTH patients had a greater risk of non-vascular dementia (hazard ratio, 1.21; 95% CI, 1.09-1.34 than the non-TTH group.TTH patients have a future risk of dementia, indicating a potentially linked disease pathophysiology that warrants further study. The association between TTH and dementia is greater in women, older adults, and with comorbidities. Clinicians should be aware of potential dementia comorbidity in TTH patients.

    Dementia associated with cerebrovascular disease is common. It has been reported that ∼30% of elderly patients who survive stroke develop delayed dementia (post-stroke dementia), with most cases being diagnosed as vascular dementia. The pathological substrates associated with post-stroke or vascular dementia are poorly understood, particularly those associated with executive dysfunction. Three separate yet interconnecting circuits control executive function within the frontal lobe involving the dorsolateral prefrontal cortex, anterior cingulate cortex and the orbitofrontal cortex. We used stereological methods, along with immunohistological and related cell morphometric analysis, to examine densities and volumes of pyramidal neurons of the dorsolateral prefrontal cortex, anterior cingulate cortex and orbitofrontal cortex in the frontal lobe from a total of 90 elderly subjects (age range 71-98 years). Post-mortem brain tissues from post-stroke dementia and post-stroke patients with no dementia were derived from our prospective Cognitive Function After Stroke study. We also examined, in parallel, samples from ageing controls and similar age subjects pathologically diagnosed with Alzheimer's disease, mixed Alzheimer's disease and vascular dementia, and vascular dementia. We found pyramidal cell volumes in layers III and V in the dorsolateral prefrontal cortex of post-stroke and vascular dementia and, of mixed and Alzheimer's disease subjects to be reduced by 30-40% compared to post-stroke patients with no dementia and controls. There were no significant changes in neuronal volumes in either the anterior cingulate or orbitofrontal cortices. Remarkably, pyramidal neurons within the orbitofrontal cortex were also found to be smaller in size when compared to those in the other two neocortical regions. To relate the cell changes to cognitive function, we noted significant correlations between neuronal volumes and total CAMCOG, orientation and memory scores and clinical

  8. Clinical pearls: factors affecting reported contraceptive efficacy rates in clinical studies.

    Current combination oral contraceptives (OCs) are among the most popular, safe, and effective methods of reversible contraception. There are, however, many factors that can affect contraceptive failure rates as reported in clinical trials, including subject characteristics, factors related to study methodology and data analysis, and publication biases. The variability of these factors among clinical trials makes meaningful comparisons of contraceptive efficacy data across studies difficult, if not misleading or erroneous. It is even more difficult to reconcile the differences between clinical trial efficacy rates and everyday use rates; for instance, the National Survey of Family Growth reported that the rate of OC failure is close to 8% in the United States, which is higher than rates reported in clinical trials. Thus, it is important for the clinician to consider the many factors that can influence reporting of contraceptive failure rates in clinical trials and be aware of the limitations in differentiating OCs on the basis of contraceptive efficacy derived from clinical trial data. Furthermore, clinical trial data may not accurately predict contraceptive efficacy in everyday use.

    Objective To evaluate the clinical efficacy of Donepezil in the treatment of senile dementia. Methods A total of 106 senile dementia patients admitted to our hospital were randomly divided into treatment group ( n = 53 ) and control group ( n =53 ). The two groups were both given primary treatment, and the treatment group was given additional Donepezil treatment. Clinical symptoms, physical signs, MMSE score and ADL score were compared between the two groups before treatment, three months and two years after treatment. Results Among the 106 senile dementia patients, 44 cases were male ( 41. 5% ) and 62 cases were female ( 58. 5% ); the patients were aged from 60 to 90, and 82 cases were from 60 to 75 ( 77. 3% ) and 24 cases were from 76 to 90 ( 22.7% ); 73 cases were under college degree ( 68. 87% ) and 33 cases were college degree or above ( 31. 13% ); 72 cases had Alzheimer's disease ( AD ) ( 67. 9% ), 23 cases had vascular dementia ( VaD ) ( 21. 7% ) and 11 cases had other dementia ( 10. 4% ). 92 cases were followed up and 14 cases lost following up during the two - year follow up. The MMSE score and ADL score before treatment and on three - month following up between the two groups showed no statistically significant difference ( P > 0. 05 ), but showed statistically significant differences on two - year following up ( P 0. 05 ). Conclusion Donepezil is safe and effective treatment for senile dementia with little adverse reaction. Donepezil may be regarded as one of best treatments for senile dementia.%目的 探讨盐酸多奈哌齐治疗老年痴呆患者的临床疗效.方法 选择2009年1月-2010年9月106例本院就诊的老年痴呆患者,随机分为治疗组53例及对照组53例,两组均给予基础治疗,治疗组在此基础上给予盐酸多奈哌齐治疗.选择治疗前、随访3个月时及2年时患者的临床症状、体征及简易精神状况检查表(MMSE)评分、日常生活能力量表(ADL)评分进行分析比较.结果 106

    Dementia is a major burden for many countries including South Korea, where life expectancy is continuously growing and the proportion of aged people is rapidly growing. Neurodegenerative disorders, such as, Alzheimer disease, dementia with Lewy bodies, frontotemporal dementia. Parkinson disease, progressive supranuclear palsy, corticobasal degeneration, Huntington disease, can cause dementia, and cerebrovascular disease also can cause dementia. Depression or hypothyroidism also can cause cognitive deficits, but they are reversible by management of underlying cause unlike the forementioned dementias. Therefore these are called pseudodementia. We are entering an era of dementia care that will be based upon the identification of potentially modifiable risk factors and early disease markers, and the application of new drugs postpone progression of dementias or target specific proteins that cause dementia. Efficient pharmacologic treatment of dementia needs not only to distinguish underlying causes of dementia but also to be installed as soon as possible. Therefore, differential diagnosis and early diagnosis of dementia are utmost importance. F-18 FDG PET is useful for clarifying dementing diseases and is also useful for early detection of the disease. Purpose of this article is to review the current value of FDG PET for dementing diseases including differential diagnosis of dementia and prediction of evolving dementia.

    2015-04-01

    Novel diagnostic methods, such as cerebrospinal fluid-based neurochemical dementia diagnostics (CSF-NDD) and [18F] amyloid positron emission tomography (PET) are meanwhile recommended for specific indications by international guidelines for the improved early and differential diagnostics of multigenic (sporadic) Alzheimer's dementia (AD). In the case of CSF-NDD the German neuropsychiatric guidelines have already been validated on the S3 level of evidence (http://www.DGPPN.de) and the additional consideration of [18F] amyloid-PET in the current update of the guidelines is to be expected. By means of CSF-NDD and/or [18F] amyloid-PET a predictive diagnosis of incipient (preclinical) AD is also possible for patients at high risk for AD who are in prodromal stages, such as mild cognitive impairment (MCI). As accompanying (secondary) preventive therapy of AD cannot be offered a predictive molecular dementia diagnostics is not recommended by the German neuropsychiatric dementia guidelines (http://www.DGPPN.de). However, novel diagnostic approaches, which offer molecular positive diagnostics of AD have already gained high relevance in therapy research as they allow promising preventive treatment avenues to be validated directly in the clinical trial. Moreover, future blood-based dementia diagnostics by means of multiplex assays is becoming increasingly more feasible; however, so far corresponding proteomic or epigenetic assays could not be consistently validated in independent studies.

    2015-03-01

    Full Text Available Background: Watching television is a common leisure activity, not least among older people. However, watching television may become difficult when it is disturbed by symptoms of dementia. Method: A total of 284 questionnaires were handed out to relatives of people with dementia in Iceland, in the Memory Clinic of the University Hospital and in specialized units for people with dementia (6 day-care units and 8 units within nursing homes. The response rate was just below 58%. Results: Watching television was shown to play a less important role in the course of the daily life of people with dementia as soon as the symptoms of the disease became evident, and it increasingly became less relevant. So, this previous leisure activity left an ever-growing void of time to fill. However, watching television may provide an important social context for contact and togetherness during the progress of the disease, as watching television with someone close to them was important for the individuals with dementia. Conclusion: It is not a viable option for people with dementia to watch television on their own, but they may enjoy watching television while sharing this activity with a person close to them. This may even provide quality time.

    Human immunodeficiency virus (HIV)-infected women are at increased risk of invasive cervical cancer; however, screening rates remain low. The objectives of this study were to analyze a quality improvement intervention to increase cervical cancer screening rates in an urban academic HIV clinic and to identify factors associated with inadequate screening. Barriers to screening were identified by a multidisciplinary quality improvement committee at the Washington University Infectious Diseases clinic. Several strategies were developed to address these barriers. The years pre- and post-implementation were analyzed to examine the clinical impact of the intervention. A total of 422 women were seen in both the pre-implementation and post-implementation periods. In the pre-implementation period, 222 women (53%) underwent cervical cancer screening in the form of Papanicolaou (Pap) testing. In the post-implementation period, 318 women (75.3%) underwent cervical cancer screening (p screening included fewer visits attended (pre: 4.2 ± 1.5; post: 3.4 ± 1.4; p screening rates in an urban academic HIV clinic.

    Full Text Available The dementia concept has been reformulated through its history and the 19th century was remarkable in the construction of this concept as we understand it today. Like other syndromes, much of the history of the dementia concept comes from the attempt to separate it from other nosological conditions, giving it a unique identity. The fundamental elements for the arising of the dementia modern concept were: a correlation of the observed syndrome with organic-cerebral lesions; b understanding of the irreversibility of the dementia evolution; c its relation with human ageing; and d the choice of the cognitive dysfunction as a clinical marker of the dementia concept.

    Full Text Available Aims: In order to determine the prevalence of dementia and mild cognitive impairment (MCI, we conducted a population-based study in Japan. Methods: Participants included 924 subjects aged 65 years or older who resided in the town of Ama-cho. In phase 1 of the study, the Mini-Mental State Examination and Clinical Dementia Rating were administered for screening purposes. In phase 2 of the study, the subjects who screened positive were further examined by neurologists. Dementia and MCI were diagnosed by means of DSM-IV and International Working Group on MCI criteria, respectively. Results: By the prevalence date of June 1, 2010, 24 subjects had deceased or lived outside the town. In total, 723 of the remaining 900 subjects received a phase 1 test. In phase 2, 98 subjects were diagnosed with amnestic MCI, 113 subjects with non-amnestic MCI, and 82 subjects with dementia. Of the subjects who did not receive the phase 1 test, 66 subjects were diagnosed as having dementia according to data from their town medical card or the Long-term Care Insurance System. The crude prevalence of amnestic MCI, non-amnestic MCI, and dementia were 10.9, 12.6, and 16.4%, respectively. Conclusion: Consistent with the striking increase in the number of elderly individuals, we report higher prevalence of MCI and dementia in Japan than previously described.

    Several studies have shown that acute psychosocial stress and chronic psychosocial stress reduce heart rate variability (HRV). It is likely that individuals suffering from burnout have reduced HRV, as a consequence of the long-term stress exposure. This study investigated HRV in 54 patients with clinical burnout (40 women and 14 men) and in 55 individuals reporting low burnout scores (healthy; 24 women and 31 men) and 52 individuals reporting high burnout scores (non-clinical burnout; 33 women and 19 men). The participants underwent a 300s ECG recording in the supine position. Standard deviation of normal R-R intervals (SDNN) and the root mean square of successive normal interval differences (RMSSD) were derived from time domain HRV analysis. Frequency domain HRV measures; total power (TP), low frequency power (LF), high frequency power (HF), and LF/HF ratio were calculated. All HRV measures, except LF/HF ratio, were lower in the clinical burnout patients compared to both the non-clinical burnout group and the healthy group. The difference was larger between the patients and the healthy group than between the patients and the non-clinical burnout group. HRV did not differ significantly between the non-clinical burnout group and the healthy group. Low HRV in burnout patients may constitute one of the links to associated adverse health, since low HRV reflects low parasympathetic activity - and accordingly low anabolic/regenerative activity.

    Full Text Available Elizabeth C Hersch, Sharon FalzgrafVA Puget Sound Health Care System, Tacoma, Washington, USAAbstract: More than 50% of people with dementia experience behavioral and psychological symptoms of dementia (BPSD. BPSD are distressing for patients and their caregivers, and are often the reason for placement into residential care. The development of BPSD is associated with a more rapid rate of cognitive decline, greater impairment in activities of daily living, and diminished quality of life (QOL. Evaluation of BPSD includes a thorough diagnostic investigation, consideration of the etiology of the dementia, and the exclusion of other causes, such as drug-induced delirium, pain, or infection. Care of patients with BPSD involves psychosocial treatments for both the patient and family. BPSD may respond to those environmental and psychosocial interventions, however, drug therapy is often required for more severe presentations. There are multiple classes of drugs used for BPSD, including antipsychotics, anticonvulsants, antidepressants, anxiolytics, cholinesterase inhibitors and NMDA modulators, but the evidence base for pharmacological management is poor, there is no clear standard of care, and treatment is often based on local pharmacotherapy customs. Clinicians should discuss the potential risks and benefits of treatment with patients and their surrogate decision makers, and must ensure a balance between side effects and tolerability compared with clinical benefit and QOL.Keywords: dementia, management, behavioral symptoms, psychological symptoms

    Stephan Seiler

    Full Text Available OBJECTIVE: To assess the influence of cognitive, functional and behavioral factors, co-morbidities as well as caregiver characteristics on driving cessation in dementia patients. METHODS: The study cohort consists of those 240 dementia cases of the ongoing prospective registry on dementia in Austria (PRODEM who were former or current car-drivers (mean age 74.2 (±8.8 years, 39.6% females, 80.8% Alzheimer's disease. Reasons for driving cessation were assessed with the patients' caregivers. Standardized questionnaires were used to evaluate patient- and caregiver characteristics. Cognitive functioning was determined by Mini-Mental State Examination (MMSE, the CERAD neuropsychological test battery and Clinical Dementia Rating (CDR, activities of daily living (ADL by the Disability Assessment for Dementia, behavior by the Neuropsychiatric Inventory (NPI and caregiver burden by the Zarit burden scale. RESULTS: Among subjects who had ceased driving, 136 (93.8% did so because of "Unacceptable risk" according to caregiver's judgment. Car accidents and revocation of the driving license were responsible in 8 (5.5% and 1(0.7% participant, respectively. Female gender (OR 5.057; 95%CI 1.803-14.180; p = 0.002, constructional abilities (OR 0.611; 95%CI 0.445-0.839; p = 0.002 and impairment in Activities of Daily Living (OR 0.941; 95%CI 0.911-0.973; p<0.001 were the only significant and independent associates of driving cessation. In multivariate analysis none of the currently proposed screening tools for assessment of fitness to drive in elderly subjects including the MMSE and CDR were significantly associated with driving cessation. CONCLUSION: The risk-estimate of caregivers, but not car accidents or revocation of the driving license determines if dementia patients cease driving. Female gender and increasing impairment in constructional abilities and ADL raise the probability for driving cessation. If any of these factors also relates to undesired

  2. Linear and Nonlinear Heart Rate Variability Indexes in Clinical Practice

    2012-01-01

    Full Text Available Biological organisms have intrinsic control systems that act in response to internal and external stimuli maintaining homeostasis. Human heart rate is not regular and varies in time and such variability, also known as heart rate variability (HRV, is not random. HRV depends upon organism's physiologic and/or pathologic state. Physicians are always interested in predicting patient's risk of developing major and life-threatening complications. Understanding biological signals behavior helps to characterize patient's state and might represent a step toward a better care. The main advantage of signals such as HRV indexes is that it can be calculated in real time in noninvasive manner, while all current biomarkers used in clinical practice are discrete and imply blood sample analysis. In this paper HRV linear and nonlinear indexes are reviewed and data from real patients are provided to show how these indexes might be used in clinical practice.

    The dementia prevention consists of three steps, primary prevention of dementia is to prevent from normal and mild cognitive impairment to dementia, secondary prevention is early detection and early treatment of dementia, and tertiary prevention is three stages of progress prevention of dementia. Primary prevention of dementia had been considered impossible until recently, but potential scientific evidence has been shown recently. The fact that 4.62 million people are person with dementia and 400 million people are person with mild cognitive impairment are considered to be urgent problem and we must intend to perform dementia prevention from primary to tertiary prevention thoroughly. We perform dementia screening using touch panel type computer and we recommend person with mild cognitive impairment to join dementia prevention classroom. Therefore, we can prevent progression from mild cognitive impairment to dementia (primary prevention). Early diagnosis and introduction to the specialized medical institution are needed if you find early stage of dementia and treat early (secondary prevention). To prevent progression by the appropriate drug treatment and care for dementia is required (tertiary prevention).

    Curiati, Jose A. E.; Jacob-Filho, Wilson

    2017-01-01

    Background Hospitalized older adults with preexisting dementia have increased risk of having delirium, but little is known regarding the effect of delirium superimposed on dementia (DSD) on the outcomes of these patients. Our aim was to investigate the association between DSD and hospital mortality and 12-mo mortality in hospitalized older adults. Methods and findings This was a prospective cohort study completed in the geriatric ward of a university hospital in São Paulo, Brazil. We included 1,409 hospitalizations of acutely ill patients aged 60 y and over from January 2009 to June 2015. Main variables and measures included dementia and dementia severity (Informant Questionnaire on Cognitive Decline in the Elderly, Clinical Dementia Rating) and delirium (Confusion Assessment Method). Primary outcomes were time to death in the hospital and time to death in 12 mo (for the discharged sample). Comprehensive geriatric assessment was performed at admission, and additional clinical data were documented upon death or discharge. Cases were categorized into four groups (no delirium or dementia, dementia alone, delirium alone, and DSD). The no delirium/dementia group was defined as the referent category for comparisons, and multivariate analyses were performed using Cox proportional hazards models adjusted for possible confounders (sociodemographic information, medical history and physical examination data, functional and nutritional status, polypharmacy, and laboratory covariates). Overall, 61% were women and 39% had dementia, with a mean age of 80 y. Dementia alone was observed in 13% of the cases, with delirium alone in 21% and DSD in 26% of the cases. In-hospital mortality was 8% for patients without delirium or dementia, 12% for patients with dementia alone, 29% for patients with delirium alone, and 32% for DSD patients (Pearson Chi-square = 112, p < 0.001). DSD and delirium alone were independently associated with in-hospital mortality, with respective hazard ratios

    Alzheimer's disease (AD) is the most prevalent neurodegenerative disease in the world. Most AD patients become dependent on their relatives, i.e. family caregivers. Providing care to a person with AD influences caregiver's life and leads to feelings of grief, which often precede caregiver depression. The purpose of the article was to evaluate the Meuser and Marwit Caregiver Grief Inventory (MM-CGI-50) for use in Polish family caregivers and to find out determinants of grief of family caregivers of AD individuals living in Poland. A sample of 151 spouse and adult child caregivers of community-dwelling AD patients (95 females and 56 males) was interviewed to determine the influence of such factors as caregiver's age, gender, family relation to the care recipient (CR) and caregiving-related changes in caregiver's working time, leisure time and material status to find out the impact of caregiving role on intensity of caregiver grief. Caregiver grief was measured by means of MM-CGI-50. Additionally, carers were administered a questionnaire including patient's and caregiver's demographics. Also, CR's dementia assessment was informant-based and determined with investigator-administered clinical dementia rating (CDR) scale. Of all analyzed factors, only caregiver's informant dementia rating significantly influenced caregiver grief. To conclude, the effect of caregiver's age, gender, family relation to the CR and caregiving-related changes in caregiver's working time; leisure time and material status could not be found. To add, MM-CGI-50 can be effectively used to assess grief in Polish family caregivers of AD patients.

    2008-01-01

    Full Text Available Amyotrophic lateral sclerosis (ALS with dementia (ALS-D is known to exhibit characteristics of frontotemporal dementia. However, in clinical situations, it is often difficult to evaluate their cognitive functions because of impaired voluntary speech and physical disabilities. In order to identify characteristic and diagnostic cognitive symptoms of relatively advanced ALS-D patients, we retrospectively reviewed the clinical features of seven cases of clinically definitive ALS who had dementia, impaired voluntary speech, and physical disability. Their medical records showed that six out of seven patients made writing errors, and all of the patients demonstrated anosognosia. The writing errors consisted of paragraphia such as substitution, omission, or syntactic errors with individual differences in error types. Dissociation between kana and kanji were also observed. Anosognosia was evaluated by a self-rating scale with which the patients and the medical staff evaluated the patient's physical ability; the results indicated a large discrepancy between the evaluation by the patients and the medical staff. We emphasize that aphasic writing errors have been underestimated, particularly in ALS-D patients with impaired voluntary speech. We also reported that anosognosia was the most important and quantifiable symptom in ALS-D. The relationship between writing errors and anosognosia should be investigated further.

    Background: Potentially inappropriate medication (PIM) in older people is a risk factor for adverse drug effects. This risk is even higher in older people with dementia (PWD). Objective: Our study aimed to determine (1) the prevalence of PIM among primary care patients who were screened positive for dementia and (2) the sociodemographic and clinical variables associated with the use of PIM. Methods: DelpHi-MV (Dementia: life- and person-centered help in Mecklenburg–Western Pomerania) is a general practitioner-based, cluster-randomized, controlled intervention study to implement and evaluate an innovative concept of collaborative dementia care management in Germany. The comprehensive baseline assessment includes a home medication review. The present analyses are based on the data from 448 study participants (age 70+, DemTect benzodiazepines, and analgetics. The most frequently prescribed PIMs were amitriptyline, etoricoxib, and doxazosin. (2) Use of a PIM was significantly associated with a diagnosis of a mental or behavioral disorder. Conclusions: The prescription rate of PIMs for community-dwelling PWD was comparable with the rates found for the general population of older people in Germany (20–29%). Antidepressants with anticholinergic properties and long-acting benzodiazepines were the most prescribed PIMs, despite having an unfavorable benefit-risk ratio. This high prevalence of PIM prescriptions in a vulnerable population of PWD indicates that standard care for dementia should include careful medication review and management. PMID:27716668

    2005-01-01

    The integration of research into clinical practice to conduct effectiveness studies faces multiple obstacles. One obstacle is the burden of completing research measures of outcome. A simple, reliable, and valid measure that could be rated at every visit, incorporated into a clinician's progress note, and reflect the DSM-IV definition of a major depressive episode (including partial and full remission from the episode) would enhance the ability to conduct effectiveness research. The goal of the present study was to examine the reliability and validity of such a measure. Three hundred and three psychiatric outpatients who were being treated for a DSM-IV major depressive episode were rated on the Standardized Clinical Outcome Rating for Depression (SCOR-D), 17-item Hamilton Rating Scale for Depression, Montgomery-Asberg Depression Rating Scale, and the Global Assessment of Functioning. We examined the correlation between the SCOR-D and the other measures, and conducted an analyses of variance to compare mean values on these measures for each rating point on the SCOR-D. The inter-rater reliability of the SCOR-D dimensional ratings and categorical determination of remission were high. The SCOR-D was highly correlated with the other scales, and there were significant differences on the other measures of depression severity between each adjacent rating level of the SCOR-D. The SCOR-D is a brief standardized outcome measure linked to the DSM-IV approach toward defining remission that can be incorporated into routine clinical practice without adding undue burden to the treating clinician with some evidence of reliability and validity. This measure could make it more feasible to conduct effectiveness studies in clinical practice.

    Full Text Available Steven F Werder1,21Kansas University School of Medicine – Wichita, Wichita, KS, USA; 2Community Health Center of Southeast Kansas, Pittsburg, KS, USAIntroduction: Although consensus guidelines recommend checking serum B12 in patients with dementia, clinicians are often faced with various questions: (1 Which patients should be tested? (2 What test should be ordered? (3 How are inferences made from such testing? (4 In addition to serum B12, should other tests be ordered? (5 Is B12 deficiency compatible with dementia of the Alzheimer’s type? (6 What is to be expected from treatment? (7 How is B12 deficiency treated?Methods: On January 31st, 2009, a Medline search was performed revealing 1,627 citations related to cobalamin deficiency, hyperhomocysteinemia, and dementia. After limiting the search terms, all abstracts and/or articles and other references were categorized into six major groups (general, biochemistry, manifestations, associations and risks, evaluation, and treatment and then reviewed in answering the above questions.Results: The six major groups above are described in detail. Seventy-five key studies, series, and clinical trials were identified. Evidence-based suggestions for patient management were developed.Discussion: Evidence is convincing that hyperhomocysteinemia, with or without hypovitaminosis B12, is a risk factor for dementia. In the absence of hyperhomocysteinemia, evidence is less convincing that hypovitaminosis B12 is a risk factor for dementia. B12 deficiency manifestations are variable and include abnormal psychiatric, neurological, gastrointestinal, and hematological findings. Radiological images of individuals with hyperhomocysteinemia frequently demonstrate leukoaraiosis. Assessing serum B12 and treatment of B12 deficiency is crucial for those cases in which pernicious anemia is suspected and may be useful for mild cognitive impairment and mild to moderate dementia. The serum B12 level is the standard initial test

    Given that there may well be no significant advances in drug development before 2025, prevention of dementia-Alzheimer's disease through the management of vascular and lifestyle-related risk factors may be a more realistic goal than treatment. Level of education and cognitive reserve assessment in neuropsychological testing deserve attention, as well as cultural, social, and economic aspects of caregiving. Assistive technologies for dementia care remain complex. Serious games are emerging as virtual educational and pleasurable tools, designed for individual and cooperative skill building. Public policies are likely to pursue improving awareness and understanding of dementia; providing good quality early diagnosis and intervention for all; improving quality of care from diagnosis to the end of life, using clinical and economic end points; delivering dementia strategies quicker, with an impact on more people. Dementia should remain presented as a stand-alone concept, distinct from frailty or loss of autonomy. The basic science of sensory impairment and social engagement in people with dementia needs to be developed. E-learning and serious games programs may enhance public and professional education. Faced with funding shortage, new professional dynamics and economic models may emerge through coordinated, flexible research networks. Psychosocial research could be viewed as an investment in quality of care, rather than an academic achievement in a few centers of excellence. This would help provide a competitive advantage to the best operators. Stemming from care needs, a logical, systems approach to dementia care environment through organizational, architectural, and psychosocial interventions may be developed, to help reduce symptoms in people with dementia and enhance quality of life. Dementia-friendly environments, culture, and domesticity are key factors for such interventions.

  7. Music and dementia.

    Baird, Amee; Samson, Séverine

    2015-01-01

    There is an increasing incidence of dementia in our aging population, and consequently an urgent need to develop treatments and activities that may alleviate the symptoms of dementia. Accumulating evidence shows that persons with dementia enjoy music, and their ability to respond to music is potentially preserved even in the late or severe stages of dementia when verbal communication may have ceased. Media interest in this topic has contributed to the public perception that music abilities are an "island of preservation" in an otherwise cognitively impaired person with dementia. In this chapter, we review the current literature on music cognition in dementia and show that there has been very scarce rigorous scientific investigation of this issue, and that various types of music memory exist and are differentially impaired in the different types of dementia. Furthermore, we discuss the recent development of music activities as a nonpharmacological treatment for dementia and highlight the methodological limitations of the current literature on this topic. While it has been reported that music activities can improve behavior, (particularly agitation), mood, and cognition in persons with dementia, recent large-scale randomized control studies have questioned the specificity of the effect of music and found that it is no more beneficial than other pleasant activities. Nevertheless, music is unique in its powerful ability to elicit both memories and emotions. This can provide an important link to individual's past and a means of nonverbal communication with carers, which make it an ideal stimulus for persons with dementia.

    Full Text Available Down syndrome is an intellectual disability disorder in which language and, specifically, verbal fluency are strongly impaired domains; nearly all adults show neuropathology of Alzheimer’s disease, including amyloid deposition by their fifth decade of life. In the general population, verbal fluency deficits are considered a strong Alzheimer’s disease predictor being the Semantic Verbal Fluency Task (SVFT a useful tool for enhancing early diagnostic. However, there is a lack of information about the association between the semantic verbal fluency pattern (SVFP and the biological amyloidosis markers in Down syndrome. In the current study, we used the SVFT in young adults with Down syndrome to characterize their SVFP, assessing total generated words, clustering, and switching. We then explored its association with early indicators of dementia, adaptive behavior and amyloidosis biomarkers, using the Dementia Questionnaire for Persons with Intellectual Disability (DMR, the Adaptive Behavior Assessment System-Second Edition (ABAS-II, and plasma levels of Aβ peptides (Aβ40 and Aβ42, as a potent biomarker of Alzheimer's disease. In Down syndrome, worse performance in SVFT and poorer communication skills were associated with higher plasma Aβ42 concentrations, a higher DMR score and impaired communication skills (ABAS–II. The total word production and switching ability in SVFT were good indicators of plasma Aβ42 concentration. In conclusion, we propose the SVFT as a good screening test for early detection of dementia and amyloidosis in young adults with Down syndrome.

However, there is a lack of information about the association between the semantic verbal fluency pattern (SVFP) and the biological amyloidosis markers in DS. In the current study, we used the SVFT in young adults with DS to characterize their SVFP, assessing total generated words, clustering, and switching. We then explored its association with early indicators of dementia, adaptive behavior and amyloidosis biomarkers, using the Dementia Questionnaire for Persons with Intellectual Disability (DMR), the Adaptive Behavior Assessment System-Second Edition (ABAS-II), and plasma levels of Aβ peptides (Aβ40 and Aβ42), as a potent biomarker of AD. In DS, worse performance in SVFT and poorer communication skills were associated with higher plasma Aβ42 concentrations, a higher DMR score and impaired communication skills (ABAS–II). The total word production and switching ability in SVFT were good indicators of plasma Aβ42 concentration. In conclusion, we propose the SVFT as a good screening test for early detection of dementia and amyloidosis in young adults with DS. PMID:26635555

  10. Economic Impact of Dementia by Disease Severity: Exploring the Relationship between Stage of Dementia and Cost of Care in Taiwan.

    Directory of Open Access Journals (Sweden)

    Li-Jung Elizabeth Ku

    Full Text Available Given the shortage of cost-of-illness studies in dementia outside of the Western population, the current study estimated the annual cost of dementia in Taiwan and assessed whether different categories of care costs vary by severity using multiple disease-severity measures.This study included 231 dementia patient-caregiver dyads in a dementia clinic at a national university hospital in southern Taiwan. Three disease measures including cognitive, functional, and behavioral disturbances were obtained from patients based on medical history. A societal perspective was used to estimate the total costs of dementia according to three cost sub-categories. The association between dementia severity and cost of care was examined through bivariate and multivariate analyses.Total costs of care for moderate dementia patient were 1.4 times the costs for mild dementia and doubled from mild to severe dementia among our community-dwelling dementia sample. Multivariate analysis indicated that functional declines had a greater impact on all cost outcomes as compared to behavioral disturbance, which showed no impact on any costs. Informal care costs accounted for the greatest share in total cost of care for both mild (42% and severe (43% dementia patients.Since the total costs of dementia increased with severity, providing care to delay disease progression, with a focus on maintaining patient physical function, may reduce the overall cost of dementia. The greater contribution of informal care to total costs as opposed to social care also suggests a need for more publicly-funded long-term care services to assist family caregivers of dementia patients in Taiwan.

    Full Text Available BACKGROUND: Clinical practice guidelines (CPGs aim to improve professionalism in health care. However, current CPG development manuals fail to address how to include ethical issues in a systematic and transparent manner. The objective of this study was to assess the representation of ethical issues in general CPGs on dementia care. METHODS AND FINDINGS: To identify national CPGs on dementia care, five databases of guidelines were searched and national psychiatric associations were contacted in August 2011 and in June 2013. A framework for the assessment of the identified CPGs' ethical content was developed on the basis of a prior systematic review of ethical issues in dementia care. Thematic text analysis and a 4-point rating score were employed to assess how ethical issues were addressed in the identified CPGs. Twelve national CPGs were included. Thirty-one ethical issues in dementia care were identified by the prior systematic review. The proportion of these 31 ethical issues that were explicitly addressed by each CPG ranged from 22% to 77%, with a median of 49.5%. National guidelines differed substantially with respect to (a which ethical issues were represented, (b whether ethical recommendations were included, (c whether justifications or citations were provided to support recommendations, and (d to what extent the ethical issues were explained. CONCLUSIONS: Ethical issues were inconsistently addressed in national dementia guidelines, with some guidelines including most and some including few ethical issues. Guidelines should address ethical issues and how to deal with them to help the medical profession understand how to approach care of patients with dementia, and for patients, their relatives, and the general public, all of whom might seek information and advice in national guidelines. There is a need for further research to specify how detailed ethical issues and their respective recommendations can and should be addressed in dementia

    Nineteen cases with verified Hereditary Cystatin C Amyloid Angiopathy are presented. All of the cases had one or more cerebrovascular insults starting at the age of 20-41 years and survived from 10 days to 23 years after the first insult. Progressive dementia was a prominent clinical feature...... in seventeen cases of whom two presented with dementia. At the last examination the majority had severe dementia and severely abnormal EEG. Anti-cystatin C positive amyloid vascular and perivascular infiltrates were found. The resulting damage to the microvasculature of the brain and secondary hemorrhages...... and infarctions were considered to be an adequate explanation for the dementia in these cases. Skin biopsies can now probably be used to demonstrate cystatin C positive amyloid deposits conclusively in the tissues of these patients....

    As life expectancy continues to increase over time, dementia is becoming an increasingly more common problem and a major cause of disability in older persons. It is now more important than ever to identify and manage common causes of dementia given variations in disease course, treatments and the possibility for modification of risk factors. Dementia with Lewy bodies (DLB) is a dementia syndrome characterized by progressive cognitive decline, with fluctuating cognition, recurrent detailed and well-formed hallucinations, and parkinsonism. This article aims to provide an overview of current concepts of DLB, including a description of the key clinical features and neuropathology, neurochemistry, and genetics of DLB, then a discussion of the relationship of DLB with Alzheimer's disease and Parkinson's disease, and, finally, a summary of current management strategies available for this disorder.

    Full Text Available Introduction: The aims of this study were to describe the quality of life (QoL of nursing-home residents with dementia and their balance, mobility, muscle strength and daily life activity, as well as to examine the associations between QoL and levels of balance, mobility, muscle strength and daily life activity. Methods: The study is cross sectional, and 170 nursing-home residents with dementia were included. Tests: “The quality of life in late-stage dementia scale” (QUALID, Berg Balance Scale, comfortable walking speed, maximum walking speed, 30-s sit-to-stand, Barthel Index, Clinical Dementia Rating Scale, the Clock Drawing Test and the Mini-Mental State Examination (MMSE were used. Results: Our study showed that nursing-home residents with dementia are a heterogeneous group regarding registrations of QUALID and physical function measures. The scores on the QUALID ranged from 11 to 41 points. Higher scores on the 30-s sit-to-stand and Berg Balance Scale were associated with a better QUALID. For comfortable, as well as maximum, walking speed there was a trend towards better QUALID results for those participants with higher walking speed. Conclusions: Good muscle strength and balance were the most important physical performance variables significantly associated with a good QUALID score.

    Behavioral and psychological symptoms of dementia are very common in patients affected by dementia, and are associated with high rates of institutionalization. Behavioral and psychological symptoms of dementia consist of aggressive behavior, delusions, hallucinations, depression, apathy, wandering, stereotyped and inappropriate sexual behavior. Interestingly, the latter has been reported to be relatively uncommon, but causing immense distress to patients and their caregivers. The genesis of inappropriate behavior is considered a combination of neurological, psychological and social factors. Although assessment is mainly carried out by clinical observation and interviews with caregivers, the most appropriate management of behavioral and psychological symptoms of dementia, including hypersexuality, is a combination of pharmacological and non-pharmacological interventions, according to specific symptoms, degree of cognitive dysfunction and subtype of dementia. The present narrative review will mainly focus on aggressiveness, disinhibition, aberrant motor, and sexually inappropriate behavior diagnostic work-up and treatment, in an attempt to provide both the patients and their caregivers with useful information to better manage these symptoms and improve their quality of life. Space is particularly dedicated to inappropriate sexual behavior, which is still considered a neglected issue. Geriatr Gerontol Int 2016; ••: ••-••.

    We studied clinical significance of [sup 99m]Tc-L,L,-ethyl cysteine dimer ([sup 99m]Tc-ECD) SPECT study in dementia and aphasia, and compared it with [sup 99m]Tc-HMPAO SPECT study. The subjects consisted of 13 patients, including 10 patients with dementia and 3 patients with aphasia. Hypoperfusion areas were detected in 5 out of 10 patients with dementia and 2 out of 3 patients with aphasia in [sup 99m]Tc-ECD SPECT, and in 4 out of 10 patients with dementia and all of 3 patients with aphasia in [sup 99m]Tc-HMPAO SPECT. The count rate ratios in [sup 99m]Tc-ECD and [sup 99m]Tc-HMPAO SPECT were correlated well with each other, and the contrast of the [sup 99m]Tc-ECD SPECT image was equivalent or slightly higher as compared with [sup 99m]Tc-HMPAO. Therefore, [sup 99m]Tc-ECD SPECT study was considered to be useful for the evaluation of cerebral perfusion in dementia and aphasia. (author).

    Although persons with dementia are frequently hospitalized, relatively little is known about the health profile, patterns of health care use, and mortality rates for patients with dementia who access care in the emergency department (ED). We linked data from our hospital system with Medicare and Medicaid claims, Minimum Data Set, and Outcome and Assessment Information Set data to evaluate 175,652 ED visits made by 10,354 individuals with dementia and 15,020 individuals without dementia over 11 years. Survival rates after ED visits and associated charges were examined. Patients with dementia visited the ED more frequently, were hospitalized more often than patients without dementia, and had an increased odds of returning to the ED within 30 days of an index ED visit compared with persons who never had a dementia diagnosis (odds ratio, 2.29; Pdementia status (Pdementia. These results show that older adults with dementia are frequent ED visitors who have greater comorbidity, incur higher charges, are admitted to hospitals at higher rates, return to EDs at higher rates, and have higher mortality after an ED visit than patients without dementia.

    Dementia and its side effects often leave individuals unable to tell their stories or experiences. Consequently, nurses must rely strictly on clinical observations as a basis for understanding dementia--an understanding that is necessary to provide the best possible care. Relying on clinical observations leads to challenges in fully understanding the experience of living with dementia. Fictional literature gives authors license to write about individuals with dementia rather than the clinical aspects of the disease, which provides insight into the patient and family experience and illustrates their needs. The current article explores dementia through an analysis of eight literary works and insights that may help expand the quality of geriatric nursing care.

    To describe inappropriate sexual behaviour (ISB) observed in patients with dementia, we conducted searches using the Cochrane Library, PubMed, and Web of Science to find relevant articles, chapters, and books published from 1950 to 2014. Search terms used included 'hypersexuality', 'inappropriate sexual behaviors', and 'dementia'. Publications found through this indexed search were reviewed for further relevant references. Sexuality is a human's need to express intimacy, but persons with dementia may not know how to appropriately meet their needs for closeness and intimacy due to their decline in cognition. Generally, the interaction among brain, physical, psychological, and environmental factors can create what we call ISB. The most likely change in the sexual behaviour of a person with dementia is indifference. However, ISB in dementia appear to be of two types--intimacy-seeking and disinhibited--that differ in their association with dementia type, dementia severity and, possibly, other concurrent behavioural disorder. Tensions develop from uncertainties regarding which, or when, behaviours are to be considered 'inappropriate' (i.e. improper) or abnormal. While most ISB occur in the moderate to severe stages of Alzheimer's dementia, they may also be seen in early stages of frontotemporal dementia because of the lack of insight and disinhibition. ISB are often better managed by non-pharmacological means, as patients may be less responsive to psychoactive therapies, but non-pharmacological interventions do not always stop the behaviour.

    While dementia is an umbrella term for a range of degenerative brain disorders, many share similar presentations. Nurses are ideally placed to identify those at risk and empower them to access treatment and plan and prepare for their future needs--as such, they need up-to-date knowledge of the signs and symptoms of the different types of dementia to identify risk factors and make an informed diagnosis. This article, the third in a four-part series on dementia, examines the risk factors, signs, symptoms and diagnosis of dementia, as well as outlining lifestyle factors such as diet and exercise that may help to prevent the development of the condition.

    Modern imaging techniques undoubtedly are of value when applied to the study of dementia. This value, however, varies with the technique utilized, and one must distinguish between acquired and potential knowledge. Morphological imaging with computerized tomography or magnetic resonance detects or confirms certain causes of dementia (tumours, lacunae, hydrocephalus with normal CSF pressure), but it is still not sensitive and specific enough to be very useful in primary dementias. Functional imaging (essentially with emission tomography) has already provided interesting data in the study of degenerative dementia (correlations with neuropsychology, subtyping), but what is most promising is its possibilities in the physiopathological approach of the disease.

  3. The influence of primary care quality on hospital admissions for people with dementia in England: a regression analysis.

    Full Text Available To test the impact of a UK pay-for-performance indicator, the Quality and Outcomes Framework (QOF dementia review, on three types of hospital admission for people with dementia: emergency admissions where dementia was the primary diagnosis; emergency admissions for ambulatory care sensitive conditions (ACSCs; and elective admissions for cataract, hip replacement, hernia, prostate disease, or hearing loss.Count data regression analyses of hospital admissions from 8,304 English general practices from 2006/7 to 2010/11. We identified relevant admissions from national Hospital Episode Statistics and aggregated them to practice level. We merged these with practice-level data on the QOF dementia review. In the base case, the exposure measure was the reported QOF register. As dementia is commonly under-diagnosed, we tested a predicted practice register based on consensus estimates. We adjusted for practice characteristics including measures of deprivation and uptake of a social benefit to purchase care services (Attendance Allowance.In the base case analysis, higher QOF achievement had no significant effect on any type of hospital admission. However, when the predicted register was used to account for under-diagnosis, a one-percentage point improvement in QOF achievement was associated with a small reduction in emergency admissions for both dementia (-0.1%; P=0.011 and ACSCs (-0.1%; P=0.001. In areas of greater deprivation, uptake of Attendance Allowance was consistently associated with significantly lower emergency admissions. In all analyses, practices with a higher proportion of nursing home patients had significantly lower admission rates for elective and emergency care.In one of three analyses at practice level, the QOF review for dementia was associated with a small but significant reduction in unplanned hospital admissions. Given the rising prevalence of dementia, increasing pressures on acute hospital beds and poor outcomes associated with

    The objective of this study was to estimate the prevalence of antipsychotic use and investigate their association with behavioural and psychological symptoms of dementia (BPSD) and other clinical predictors. Patients with dementia, aged 65 and above and resident in 35 Alzheimer special care units were sequentially enrolled into a 18-month prospective observational study. Data on sociodemographic, cognitive, functional, behavioural and clinical characteristics and drug exposure were collected at baseline and at 6-month intervals up to 18 months. The prevalence of antipsychotic use and the association with BPSD and clinical predictors were analysed. Of the 349 patients with dementia enrolled in the study, 209 (60%) were taking at least one antipsychotic. Risperidone and promazine were the most frequently prescribed antipsychotic; 40.7% simultaneously received a benzodiazepine, 20% an antidepressant. More than 50% were still taking antipsychotics at 18 months of follow-up. No associations were found between antipsychotic use and level of cognitive impairment, basal activity of daily living disability and comorbidity. Multivariate analysis showed that the use of antipsychotics was highest in patients in the highest quartiles of Neuropsychiatric Inventory Scale score (III quartile, odds ratio: 1.63; 95% confidence interval: 1.19-2.23; IV quartile, odds ratio: 2.27; 95% confidence interval: 1.61-3.26). This study found high rate of use of antipsychotics in patients with dementia resident in Alzheimer special care units, frequent associations with other psychotropic medications and a strong correlation with BPSD.

  5. What can imaging tell us about cognitive impairment and dementia?

    Dementia is a contemporary global health issue with far reaching consequences, not only for affected individuals and their families, but for national and global socioeconomic conditions. The hallmark feature of dementia is that of irreversible cognitive decline, usually affecting memory, and impaired activities of daily living. Advances in healthcare worldwide have facilitated longer life spans, increasing the risks of developing cognitive decline and dementia in late life. Dementia remains a clinical diagnosis. The role of structural and molecular neuroimaging in patients with dementia is primarily supportive role rather than diagnostic, American and European guidelines recommending imaging to exclude treatable causes of dementia, such as tumor, hydrocephalus or intracranial haemorrhage, but also to distinguish between different dementia subtypes, the commonest of which is Alzheimer’s disease. However, this depends on the availability of these imaging techniques at individual centres. Advanced magnetic resonance imaging(MRI) techniques, such as functional connectivity MRI, diffusion tensor imaging and magnetic resonance spectroscopy, and molecular imaging techniques, such as 18 F fluoro-deoxy glucose positron emission tomography(PET), amyloid PET, tau PET, are currently within the realm of dementia research but are available for clinical use. Increasingly the research focus is on earlier identification of at risk preclinical individuals, for example due to family history. Intervention at the preclinical stages before irreversible brain damage occurs is currently the best hope of reducing the impact of dementia.

    Vascular dementia (VaD)--secondary to cerebrovascular disease (CVD)--has been traditionally distinguished from Alzheimer's disease (AD), which is a purely neurodegenerative form of dementia. However, CVDs such as lacunes and white matter lesions are common in patients with AD, whereas certain pathological changes of AD, including senile plaques and tangles, are observed in elderly patients with VaD. These findings indicate that mixed vascular-degenerative dementia (MD) is the most common cause of dementia in the elderly. In the treatment and prevention of dementia, the accurate diagnosis of each individual type of dementia is vital. However, recognizing the distinction between these diseases can be difficult in clinical practice. This article provides an overview of MD, including the incidence, diagnosis, and treatment. In particular, we emphasize that functional brain imaging, including perfusion single photon emission computed tomography and benzodiazepine receptor binding measurement, in combination with morphological imaging (such as magnetic resonance imaging) is useful for distinguishing AD, VaD and MD. In addition to antiplatelet medications, cholinesterase inhibitors and N-methyl-D-aspartic acid antagonists may be effective in treating MD. Moreover the vascular risk factors also should be treated appropriately. The article describes the need for further studies to develop a better understanding of MD.

    BACKGROUND: The number of dementia patients ceaselessly increases with the extension of the life expectancy and the ageing of the population; hence the survival rate of patients with post-stroke dementia(PSD) has become an important issue of public health. Although it is generally believed that dementia could shorten human life expectancy, there is rare report regarding the impact of PSD on the survival rate of the patients in developing countries.OBJECTIVE: To investigate the impacts of ischemic dementia on the survival rate of the patients to explore the risk factors that would affect the survival rate of patients after cerebral infarction(CI).DESIGN: A prospective randomized controlled study based on patients.SETTING: The second department of neurology of a field surgery institute in a military university hospital of Chinese PLA.PARTICIPANTS: Totally 619 cases of acute CI including 313 males and 306 females aged between 55 and 85 years old[mean of (70. 3 ±9.5) years old] were selected form the Department of Neurology of the Daping Hospital of the Third Military Medical University of Chinese PLA between 1st May 1998 and 28th December 1999.INTERVENTIONS: Data including human factor, vascular factor and CI characters of 619 cases of ischemic cerebral stroke were collected and they also received neuropsychological test. Dementia was diagnosed in CI patients at admission and 3 months after CI according to DSM-Ⅳ criteria. Two-year follow up was conducted for the analysis of survival rate in PSD patients and survival-correlated predicting factors.and survival rate in CI patientsRESULTS: Totally 146 total patients(23.6% ) were diagnosed as PSD at 3 month after CI, of which 39 cases were pre-stroke dementia and 107 cases were CI-correlated dementia. The survival rate of PSD patients was 49.3%after(19.4 ±8.3) months of follow-up. The survival rate of patients with CI-correlated dementia was 53.7% while the non-dementia patients was 92.0% after(21.3 ± 9.1 ) months of

    Stereotypies are simple or complex involuntary/unvoluntary behaviors, common in fronto-temporal dementia (FTD), but not studied in other types of degenerative dementias. The aim was to investigate stereotypy frequency and type in patients with FTD, Alzheimer's disease (AD), progressive supranuclear palsy (PSP) and Parkinson's disease with dementia (PDD) in a multicenter observational study; and to investigate the relation of stereotypies to cognitive, behavioral and motor impairment. One hundred fifty-five consecutive outpatients (45 AD, 40 FTD, 35 PSP and 35 PDD) were studied in four hospitals in northern Italy. Stereotypies were examined by the five-domain Stereotypy Rating Inventory. Cognition was examined by the Mini Mental State and Frontal Assessment Battery, neuropsychiatric symptoms by the Neuropsychiatric Inventory, and motor impairment and invalidity by the Unified Parkinson's Disease Rating Scale part III, and activities of daily living. Stereotypies were present in all groups. FTD and PDD had the greatest frequency of one-domain stereotypies; FTD also had the greatest frequency of two-or-more domain stereotypies; movement stereotypies were the most common stereotypies in all groups. AD patients had fewer stereotypies than the other groups. Stereotypies are not exclusive to FTD, but are also fairly common in PSP and PDD, though less so in AD. Stereotypies may be underpinned by dysfunctional striato-frontal circuits, known to be damaged in PSP and PDD, as well as FTD.

  13. Dementias show differential physiological responses to salient sounds

    Full Text Available Abnormal responsiveness to salient sensory signals is often a prominent feature of dementia diseases, particularly the frontotemporal lobar degenerations, but has been little studied. Here we assessed processing of one important class of salient signals, looming sounds, in canonical dementia syndromes. We manipulated tones using intensity cues to create percepts of salient approaching (‘looming’ or less salient withdrawing sounds. Pupil dilatation responses and behavioural rating responses to these stimuli were compared in patients fulfilling consensus criteria for dementia syndromes (semantic dementia, n=10; behavioural variant frontotemporal dementia, n=16, progressive non-fluent aphasia, n=12; amnestic Alzheimer’s disease, n=10 and a cohort of 26 healthy age-matched individuals. Approaching sounds were rated as more salient than withdrawing sounds by healthy older individuals but this behavioural response to salience did not differentiate healthy individuals from patients with dementia syndromes. Pupil responses to approaching sounds were greater than responses to withdrawing sounds in healthy older individuals and in patients with semantic dementia: this differential pupil response was reduced in patients with progressive nonfluent aphasia and Alzheimer’s disease relative both to the healthy control and semantic dementia groups, and did not correlate with nonverbal auditory semantic function. Autonomic responses to auditory salience are differentially affected by dementias and may constitute a novel biomarker of these diseases.

    Cerebrolysin is a parenterally administered, porcine brain-derived peptide preparation that has pharmacodynamic properties similar to those of endogenous neurotrophic factors. In several randomized, double-blind trials of up to 28 weeks' duration in patients with Alzheimer's disease, Cerebrolysin was superior to placebo in improving global outcome measures and cognitive ability. A large, randomized comparison of Cerebrolysin, donepezil or combination therapy showed beneficial effects on global measures and cognition for all three treatment groups compared with baseline. Although not as extensively studied in patients with vascular dementia, Cerebrolysin has also shown beneficial effects on global measures and cognition in this patient population. Cerebrolysin was generally well tolerated in clinical trials, with dizziness (or vertigo) being the most frequently reported adverse event. Although further studies with Cerebrolysin, including longer term trials and further exploration of its use in combination with cholinesterase inhibitors, are needed to more clearly determine its place in the management of Alzheimer's disease and vascular dementia, available data suggest that Cerebrolysin is a useful addition to the treatment options available for dementia.

    The authors examined the association of incident dementia and subtypes with age, sex, and geographic area in Europe. Incidence data from eight population-based studies carried out in seven European countries were compared and pooled. The pooled data included 835 mild to severe dementia cases and 42......,996 person-years of follow-up. In all studies a higher proportion of cases were diagnosed with AD (60 to 70% of all demented cases) than vascular dementia (VaD). The incidence of dementia and AD continued to increase with age up to age 85 years, after which rates increased in women but not men....... There was a large variation in VaD incidence across studies. In the pooled analysis, the incidence rates increased with age without any substantial difference between men and women. Surprisingly, higher incidence rates of dementia and AD were found in the very old in northwest countries than in southern countries...

    Full Text Available This study explores whether the Mini-Mental State Examination (MMSE could reliably exclude definite dementia and dementia-free cases from requiring more extensive neuropsychological investigations in memory clinic settings in Singapore. Patients with memory complaints referred for possible dementia underwent the MMSE, followed by standardized neuropsychological and clinical assessments which led to a consensus diagnosis. MMSE cut-off points were derived stratified for education (less and equal/above primary level. Results show that after education stratification, using an optimal Positive Likelihood Ratio (PLR and optimal Negative Likelihood Ratio (NLR, a higher percentage of patients were correctly identified as having dementia or dementia-free, with minimal misclassification rate. The finding suggests the MMSE can be used to exclude patients not requiring full neuropsychological assessments in a memory clinic.

    Despite considerable recent interest, the biological basis and clinical diagnosis of behavioural variant frontotemporal dementia (bvFTD) pose unresolved problems. Mentalising (the cognitive capacity to interpret the behaviour of oneself and others in terms of mental states) is impaired as a prominent feature of bvFTD, consistent with involvement of brain regions including ventro-medial prefrontal cortex (PFC), orbitofrontal cortex and anterior temporal lobes. Here, we investigated mentalising ability in a cohort of patients with bvFTD using a novel modality: music. We constructed a novel neuropsychological battery requiring attribution of affective mental or non-mental associations to musical stimuli. Mentalising performance of patients with bvFTD (n = 20) was assessed in relation to matched healthy control subjects (n = 20); patients also had a comprehensive assessment of behaviour and general neuropsychological functions. Neuroanatomical correlates of performance on the experimental tasks were investigated using voxel-based morphometry of patients' brain magnetic resonance imaging (MRI) scans. Compared to healthy control subjects, patients showed impaired ability to attribute mental states but not non-mental characteristics to music, and this deficit correlated with performance on a standard test of social inference and with carer ratings of patients' empathic capacity, but not with other potentially relevant measures of general neuropsychological function. Mentalising performance in the bvFTD group was associated with grey matter changes in anterior temporal lobe and ventro-medial PFC. These findings suggest that music can represent surrogate mental states and the ability to construct such mental representations is impaired in bvFTD, with potential implications for our understanding of the biology of bvFTD and human social cognition more broadly.

    A series of our studies on the development of the Dementia Assessment Sheet for Community-based Integrated Care System 21-items (DASC-21) were reviewed. Study 1: to examine the distribution of scores and internal reliability of DASC-21, trained nurses and researchers visited the homes of 1341 participants aged 65 years and older and living in the community. The nurses interviewed the participants and, when possible, their family members, to complete the DASC-21. Then, the Mini-Mental State Examination was carried out to select the participants of study 2. Study 2: to examine the concurrent and discriminant validity, experienced psychiatrists and psychologists, who were blind to the findings of study 1, visited the homes of 131 subjects who were selected from the participants of study 1 and completed the Clinical Dementia Rating (CDR), the Mini-Mental State Examination and the Frontal Assessment Battery (FAB). Cronbach's coefficient alpha of the DASC-21 was 0.808-0.950. Scores of the DASC-21 significantly correlated with CDR total and box scores, Mini-Mental State Examination and Frontal Assessment Battery. In an analysis of variance, CDR had the main effect on the score of the DASC-21. Receiver operating characteristic analysis showed that the DASC-21 had sufficient discriminatory ability between dementia (CDR1+) and non-dementia (CDR0 or CDR0.5; area under the curve = 0.804-0.895). When using a cut-off point of 30/31, sensitivity was 83.3-94.1% and specificity was 77.3-86.4%. The DASC-21 has sufficient reliability and validity as a tool to evaluate impairments in daily functioning and in cognitive functions, to detect dementia, and to assess the severity of dementia in the community.

    Jean Etienne Dominique Esquirol (1772-1840), after Pinel (1745-1826), stated precisely the symptoms of dementia according to the new medical definition of the word: a disease including all the states of intellectual weakness for various reasons. For example Esquirol clearly distinguished dementia from mania--that is to say our present psychoses--, and also from mental deficiency. In the same time Esquirol became more and more conscious, from 1814 (cf. his contributions to the Dictionnaire des sciences médicales, in 58 volumes, dir. Panckoucke) and 1838 (his famous work Des maladies mentales), of the very nature of senile insanity compared with other kinds of dementia.

    Background The criterion for dementia implicit in DSM-IV is widely used in research but not fully operationalised. The 10/66 Dementia Research Group sought to do this using assessments from their one phase dementia diagnostic research interview, and to validate the resulting algorithm in a population-based study in Cuba. Methods The criterion was operationalised as a computerised algorithm, applying clinical principles, based upon the 10/66 cognitive tests, clinical interview and informant reports; the Community Screening Instrument for Dementia, the CERAD 10 word list learning and animal naming tests, the Geriatric Mental State, and the History and Aetiology Schedule – Dementia Diagnosis and Subtype. This was validated in Cuba against a local clinician DSM-IV diagnosis and the 10/66 dementia diagnosis (originally calibrated probabilistically against clinician DSM-IV diagnoses in the 10/66 pilot study). Results The DSM-IV sub-criteria were plausibly distributed among clinically diagnosed dementia cases and controls. The clinician diagnoses agreed better with 10/66 dementia diagnosis than with the more conservative computerized DSM-IV algorithm. The DSM-IV algorithm was particularly likely to miss less severe dementia cases. Those with a 10/66 dementia diagnosis who did not meet the DSM-IV criterion were less cognitively and functionally impaired compared with the DSMIV confirmed cases, but still grossly impaired compared with those free of dementia. Conclusion The DSM-IV criterion, strictly applied, defines a narrow category of unambiguous dementia characterized by marked impairment. It may be specific but incompletely sensitive to clinically relevant cases. The 10/66 dementia diagnosis defines a broader category that may be more sensitive, identifying genuine cases beyond those defined by our DSM-IV algorithm, with relevance to the estimation of the population burden of this disorder.

    The age-specific prevalence rates of dementia vary widely. Studies focusing on specific age groups are needed to provide reliable estimates for healthcare providers and policy makers. We estimated the prevalence of dementia, dementia subtypes and cognitive impairment in "InveCe.Ab" (ClinicalTrials.gov, NCT01345110), a single-step multidimensional population-based study of 70-74-year olds living in Abbiategrasso (Milan, Italy). We also looked for associations with socio-demographic factors and the presence of the apolipoprotein E-ɛ4 allele. The overall dementia prevalence was 3% (95%CI: 2.1-4.1%) [Alzheimer's disease (AD): 1.2% (95%CI 0.6-1.9%); vascular dementia (VD): 1.4% (95%CI: 0.8-2.2%)]. Being single was found to be a risk factor for vascular dementia; subjects born in southern Italy were shown to be at greater risk both of overall dementia and of vascular dementia. The prevalence of cognitive impairment, with or without subjective cognitive complaints (cognitive impairment, no dementia, CIND) was 7.8% (95%CI: 6.4-9.4%). As regards the CIND subgroups, the prevalence of subjects with subjective cognitive complaints (mild cognitive impairment, MCI) was 5.0% (95%CI 3.9-6.3%), while the prevalence of those without MCI (CIND-other) was 2.8% (95%CI: 1.9-3.8). The males had a higher risk of MCI and CIND-other; the older subjects were more likely to have MCI, and those born in north-eastern Italy to have CIND-other. The prevalence of AD was higher among the apolipoprotein E-ɛ4 carriers. Our data highlight the importance of dementia and cognitive impairment in the transitional period from adulthood to old age, and reveal the presence of different associations with socio-demographic and genetic factors.

    Background and Purpose Few studies of dementia in Parkinson's disease (PD) have had long-term follow-ups. Moreover, information on the duration from the onset to the development of dementia in patients with PD is lacking. The aim of this study was to determine the median dementia-free survival time from the onset of PD to the development of dementia. Methods In total, 1,193 Korean patients with PD were recruited and assessed at regular intervals of 3–6 months. We interviewed the patients and other informants to identify impairments in the activities of daily living. The Hoehn and Yahr stage and scores on the Unified Parkinson's Disease Rating Scale and Mini Mental State Examination were evaluated annually. We used Kaplan-Meier survival analysis to estimate the cumulative proportion of dementia-free patients over time. Risk factors predicting dementia were also evaluated using Cox proportional-hazards regression models. Results The median dementia-free survival time in the Korean PD population was 19.9 years. Among the 119 patients who subsequently developed dementia, the mean duration from the onset of PD to the development of dementia was 10.6 years. A multivariate analysis identified age at onset and education period as the significant predictors of dementia. Conclusions This is the first report on dementia-free survival in patients with PD based on longitudinal data analysis from the disease onset. The median dementia-free survival time in Korean PD patients was found to be longer than expected. PMID:27730764

    This review summarises the findings and applications from neuroimaging studies in dementia with Lewy bodies (DLB), highlighting key differences between DLB and other subtypes of dementia. We also discuss the increasingly important role of imaging biomarkers in differential diagnosis and outline promising areas for future research in DLB. DLB shares common clinical, neuropsychological and pathological features with Parkinson's disease dementia and other dementia subtypes, such as Alzheimer's disease. Despite the development of consensus diagnostic criteria, the sensitivity for differential diagnosis of DLB in clinical practice remains low and many DLB patients will be misdiagnosed. The importance of developing accurate imaging markers in dementia is highlighted by the potential for treatments targeting specific molecular abnormalities as well as the responsiveness to cholinesterase inhibitors and marked neuroleptic sensitivity of DLB. We review various brain imaging techniques that have been applied to investigate DLB, including the characteristic nigrostriatal degeneration in DLB using positron emission tomography (PET) and single-photon emission computed tomography (SPECT) tracers. Dopamine transporter loss has proven to reliably differentiate DLB from other dementias and has been incorporated into the revised clinical diagnostic criteria for DLB. To date, this remains the 'gold standard' for diagnostic imaging of DLB. Regional cerebral blood flow, 18 F-fluorodeoxygluclose-PET and SPECT have also identified marked deficits in the occipital regions with relative sparing of the medial temporal lobe when compared to Alzheimer's disease. In addition, structural, diffusion, and functional magnetic resonance imaging techniques have shown alterations in structure, white matter integrity, and functional activity in DLB. We argue that the multimodal identification of DLB-specific biomarkers has the potential to improve ante-mortem diagnosis and contribute to our

    2012-09-01

    Full Text Available Abstract Background Index measures for health-related quality of life (HRQoL quantify the desirability (utility of a certain health state. The commonly used generic index measure, e.g. EuroQol: EQ-5D, may underestimate relevant areas of specific diseases, resulting in lower validity. Disease-specific index measures on the other hand combine disease-specificity and quantification of perceived quality on several health domains of a certain disease into one single figure. These instruments have been developed for several diseases, but a dementia-specific HRQoL index instrument was not yet available. Facing the increasing individual and societal burden of dementia, specific HRQoL values with metric characteristics are especially useful because they will provide vital information for health outcome research and economic evaluations. Aims of the study To develop and validate the prototype of a dementia-specific HRQoL index measure: Dementia Quality of life Instrument (DQI, as the first step towards valuation of the dementia health state. Methods For development of the DQI we created a conceptual framework based on a review of the literature, qualitative interviews with people with dementia and their carers, expert opinion and team discussion. To assess validity we undertook a survey under 241 dementia professionals. Measurements consisted of ranking (1–5 and rating (1–10 of 5 dementia-specific DQI domains (memory, orientation, independence, social activities and mood and simultaneously rating of 9 DQI-derived health states on a visual analogue scale (VAS. We also performed a cross-sectional study in a large sample of people with very mild to moderate dementia and their caregivers (N = 145 to assess feasibility and concurrent validity. In addition, caregivers valued 10 DQI and 10 EQ-5D + C derived health states of the patient simultaneously on the same VAS. Setting: outpatient clinics, nursing homes and patient residences.

All patients developed progressive word-finding difficulty and anomic speech.Ten patients complained significant memory impairment and 14 experienced behavioral disturbance.Five patients were previously diagnosed as Alzheimer' s disease (AD) and 1 as schizophrenia.All patients developed marked semantic memory impairment both for living things and nonliving things.The mean score on MMSE was 10.94 ± 8.86,with 16 cases performed incorrectly on naming.Mean score on CDT copy was 4.61 ±0.85,with 14 cases scored normally.Mean score on ADL was 29.72 ± 8.75.Cases with a 5-year course showed a significant overall decline.Fourteen cases presented behavior symptoms and scored 8.00 ± 7.22 on NPI.All patients scored worst on language domain among all the domains evaluated in FTLD-CDR.Atrophy,typically involving the left anterior temporal was shown on MRI scans.However,predominantly right temporal atrophy was observed in one patient.Atrophy confined to the temporal lobe in patients with early stage and extended to the contralateral temporal,frontal lobe,and parietal lobe as disease progression. Conclusions Current study suggested that SD tend to develop in presenile age.However,about 1/3 cases develop the disease after 65 years. Deficit in language is the earliest and

    Neurochemical research in dementia needs to move beyond descriptive inventories of neurotransmitter systems affected in the specific disorders and to link to molecular studies of mechanism and clinical studies of cognition. New advances in Alzheimer's Disease (AD), Huntington's Disease (HD), and Parkinson's Disease (PD) are being guided by models of how nerve cells die in these disorders. Theories of pathophysiology which address the cellular level need to explain the selective vulnerability of neuronal populations in the different diseases. Clinically, the importance of neurochemical studies will be increased by understanding the bridges between neural and cognitive processes. Clinicians are concerned about the nosology of dementias, diagnostic tests, and more effective therapies. The value of neurochemical studies will be enhanced to the extent that they can contribute to understanding and modifying the clinical phenomenology of these disorders. In this paper, we will briefly review what is known about the neurochemistry of dementia but focus most of our attention on establishing the linkage between this level of description and the levels of description which are either "downstream" (molecular biology) or "upstream" (cognition) in terms of a reductionistic conception of understanding the disease process. We will explore how understanding neurochemistry relates to our understanding of disease mechanism and what constraints neurochemical studies place on understanding clinical aspects of disease. We will conclude by briefly discussing some of the problems with our current understanding of the neurochemistry of dementia and how we can address those problems in the future.

    The ALS/parkinsonism-dementia complex (PDC) of Kii is an endemic disease with a diverse phenotypic expression characteristic of classical ALS, parkinsonism and dementia. Its clinical and neuropathological manifestations are similar to a syndrome found in Guam, sharing classical ALS pathology together with many neurofibrillary tangles in the brain. The incidence rates of ALS declined dramatically between the 1950s and 1980s. In the 1990 s, Kuzuhara found a high incidence of PDC with abundant neurofibrillary tangles, similar to Guamanian PDC. The incidence rates of PDC dramatically rose during the 1980s and 1990 s, and PDC replaced ALS. More than 70% of patients in the endemic region had a family history of ALS or PDC. We recently found a new gene OPTN causing ALS, and have extended its clinical survey in Japan. Two autopsied cases showed involvement of basal ganglia and/or cerebral cortex with neurofibrillary tangles. A few family members also showed dementia and parkinsonism without evidence of motor neuron disease. Moreover the penetrance seems to be incomplete. Despite these similarities, OPTN mutations were not found in the Kii patients. We speculate that the Kii/ALS-PDC could primarily be a genetic disease, and its clinical manifestation is modified by other genes or environmental factors.

    The multifaceted nature of the pathology of dementia spectrum disorders has complicated their management and the development of effective treatments. This is despite the fact that they are far from uncommon, with Alzheimer's disease (AD) alone affecting 35 million people worldwide. The cholinergic system has been found to be crucially involved in cognitive function, with cholinergic dysfunction playing a pivotal role in the pathophysiology of dementia. The use of molecular imaging such as SPECT and PET for tagging targets within the cholinergic system has shown promise for elucidating key aspects of underlying pathology in dementia spectrum disorders, including AD or parkinsonian dementias. SPECT and PET studies using selective radioligands for cholinergic markers, such as [{sup 11}C]MP4A and [{sup 11}C]PMP PET for acetylcholinesterase (AChE), [{sup 123}I]5IA SPECT for the α{sub 4}β{sub 2} nicotinic acetylcholine receptor and [{sup 123}I]IBVM SPECT for the vesicular acetylcholine transporter, have been developed in an attempt to clarify those aspects of the diseases that remain unclear. This has led to a variety of findings, such as cortical AChE being significantly reduced in Parkinson's disease (PD), PD with dementia (PDD) and AD, as well as correlating with certain aspects of cognitive function such as attention and working memory. Thalamic AChE is significantly reduced in progressive supranuclear palsy (PSP) and multiple system atrophy, whilst it is not affected in PD. Some of these findings have brought about suggestions for the improvement of clinical practice, such as the use of a thalamic/cortical AChE ratio to differentiate between PD and PSP, two diseases that could overlap in terms of initial clinical presentation. Here, we review the findings from molecular imaging studies that have investigated the role of the cholinergic system in dementia spectrum disorders. (orig.)

    Full Text Available Objective: The objective of this study was to compare the occurrence and severity of behavioral and psychological symptoms of dementia (BPSD between vascular dementia (VaD and vascular cognitive impairment-no dementia (VCI-ND. Materials and Methods: Consecutive patients presenting with cognitive impairment at least 3 months after an ischemic stroke and with a Hachinski Ischemic Score ≥4 were included. VaD was diagnosed as per National Institute of Neurological Disorders and Stroke - Association Internationale pour la Recherche et l′Enseignement en Neurosciences criteria for probable VaD and VCI-ND on the lines of the Canadian study of health and aging. The severity of cognitive impairment and the behavioral/psychological symptoms were studied by means of the clinical dementia rating scale and the neuropsychiatric inventory (NPI respectively. Results: All patients with VaD and 89% of those with VCI-ND had at least one BPSD. The mean no. of symptoms per patient and the total NPI scores were higher in VaD than in VCI-ND. Apathy and night-time behavior disturbances were significantly more common and severe in VaD. Conclusions: BPSD are very common both in VCI-ND and in VaD. The profile of BPSD is similar in both groups, albeit more severe in VaD. The net burden of BPSD is higher in VaD as compared to VCI-ND.

    2012-03-01

    Full Text Available Objectives: To explore the relationship between white matter hyperintensities (WMH and the prevalence and course of depressive symptoms in mild Alzheimer’s disease (AD and Lewy body dementia. Design: This is a prospective cohort study conducted in secondary care outpatient clinics in western Norway. Subjects: The study population consisted of 77 elderly people with mild dementia diagnosed according to standardised criteria. Methods: Structured clinical interviews and physical, neurological, psychiatric, and neuropsychological examinations were performed and routine blood tests were taken. Depression was assessed using the depression subitem of the Neuropsychiatric Inventory and the Montgomery-Åsberg Depression Rating Scale (MADRS. A standardised protocol for magnetic resonance imaging scan was used, and the volumes of WMH were quantified using an automated method, followed by manual editing. Results: The volumes of total and frontal deep WMH were significantly and positively correlated with baseline severity of depressive symptoms, and depressed patients had significantly higher volumes of total and frontal deep WMH than non-depressed patients. Higher volumes of WMH were also associated with having a high MADRS score and incident and persistent depression at follow-up. After adjustment for potential confounders, frontal deep WMH, in addition to prior depression and non-AD dementia, were still significantly associated with baseline depressive symptoms (p = 0.015, OR 3.703, 95% CI 1.294–10.593. Similar results emerged for total WMH. Conclusion: In elderly people with mild dementia, volumes of WMH, in particular frontal deep WMH, were positively correlated with baseline severity of depressive symptoms, and seemed to be associated with persistent and incident depression at follow-up. Further studies of the mechanisms that determine the course of depression in mild dementia are needed.

    2012-10-01

    In addition to diagnostically decisive cognitive problems, behavioural and psychological symptoms (BPSD) are frequent among people with dementia, including sexually related behavioural problems. This paper provides an overview on the state of knowledge about these problems. Research on this topic is hampered by the absence of unanimous definitions, aetiological classifications, and diagnostic instruments. The wide range of prevalence rates reported (1.8 - 18 %) originate from the heterogenity of study samples as well as in the variety of definitions and instruments employed. Regarding aetiology, dysfunctions in various cortical regions are being discussed. Sexually related behavioural problems are more prevalent in men and among patients with vascular, frontotemporal and Parkinson-associated forms of dementia, as compared with dementias of the Alzheimer type. The pharmacological and non-pharmacological treatment strategies published to date have not been sufficiently studied.

    The Montessori method was initially applied to children, but now it has also been applied to people with dementia. The purpose of this study is to systematically review the research on the effectiveness of this method using Medical Literature Analysis and Retrieval System Online (Medline) with the keywords dementia and Montessori method. We selected lo studies, in which there were significant improvements in participation and constructive engagement, and reduction of negative affects and passive engagement. Nevertheless, systematic reviews about this non-pharmacological intervention in dementia rate this method as weak in terms of effectiveness. This apparent discrepancy can be explained because the Montessori method may have, in fact, a small influence on dimensions such as behavioral problems, or because there is no research about this method with high levels of control, such as the presence of several control groups or a double-blind study.

    通过既往对血管性痴呆(VaD)病情及证候的系统观察发现,其病情演变存在平台期、波动期和下滑期,各期证候特点不同、病情演化趋势不同。在此基础上,本文提出分期辨证、各期采取不同治疗原则的观点:平台期,充分发挥中医药整体调节的作用,延缓病程进展;波动下滑期,采取中医急救措施或中西医结合治疗,有效控制和防止阶梯样下滑。VaD又是多因素性疾病,涉及生物社会心理范畴,控制多种VaD相关危险因素并结合各种康复措施的综合治疗,对改善患者生活质量、稳定病情同样具有重要意义。%It was found by the authors through a systematical analysis of the past cases that there were 3 stages in the development of vascular dementia, namely the plateau, undulation and staircase-descent, which showed different characteristic symptoms and developing tendencies. For diagnosing and treating vascular dementia, the authors raised the viewpoint of adopting TCM differentiation of clinical stages and using different treatments at different stages. According to the authors, when vascular dementia reaches a plateau, TCM therapies for regulating the whole function of the body should be fully used to delay its development; when it reaches the stages of undulation and staircase-descent, TCM emergency treatment or combined therapies of TCM and modern medicine should be adopted in order to effectively control and prevent the staircase-descent of the disease. The authors hold that vascular dementia is a multifactor disease involving biological, sociological and psychological fields; and it is important for improving the living quality and stabilizing the state of illness of the patients to control the various relative risk factors and to adopt the combined treatments involving various rehabilitating measures.

  13. Behavioral and Psychological Symptoms of Dementia

    Directory of Open Access Journals (Sweden)

    Joaquim eCerejeira

    2012-05-01

    Full Text Available Behavioral and psychological symptoms of dementia (BPSD, also known as neuropsychiatric symptoms, represent a heterogeneous group of non-cognitive symptoms and behaviors occurring in subjects with dementia. BPSD constitute a major component of the dementia syndrome irrespective of its subtype. They are as clinically relevant as cognitive symptoms as they strongly correlate with the degree of functional and cognitive impairment. BPSD include agitation, aberrant motor behavior, anxiety, elation, irritability, depression, apathy, disinhibition, delusions, hallucinations, and sleep or appetite changes. It is estimated that BPSD affect up to 90% of all dementia subjects over the course of their illness, and is independently associated with poor outcomes, including distress among patients and caregivers, long term hospitalization, misuse of medication and increased health care costs. Although these symptoms can be present individually it is more common that various psychopathological features co-occur simultaneously in the same patient. Thus, categorization of BPSD in clusters taking into account their natural course, prognosis and treatment response may be useful in the clinical practice. The pathogenesis of BPSD has not been clearly delineated but it is probably the result of a complex interplay of psychological, social and biological factors. Recent studies have emphasized the role of neurochemical, neuropathological and genetic factors underlying the clinical manifestations of BPSD. A high degree of clinical expertise is crucial to appropriately recognize and manage the neuropsychiatric symptoms in a patient with dementia. Combination of non-pharmacological and careful use of pharmacological interventions is the recommended therapeutic for managing BPSD. Given the modest efficacy of current strategies, there is an urgent need to identify novel pharmacological targets and develop new non-pharmacological approaches to improve the adverse outcomes

Picture pairs of three unfamiliar faces with liked, disliked, or neutral faces, that were rated prior to the presentation, were presented 10 times each to a group of dementia patients (N = 15 and healthy controls (N = 14 in random order. Valence ratings of all faces were assessed before and after presentation. In contrast to controls, dementia patients changed their valence ratings of unfamiliar faces according to their pairing with either a liked or disliked face, although they were not able to explicitly assign the picture pairs after the presentation. Our finding suggests preserved evaluative conditioning in dementia patients. However, the result has to be considered preliminary, as it is unclear which factors prevented the predicted rating changes in the expected direction in the control group.

    Markers of cardiac dysfunction such as amino terminal pro-brain natriuretic peptide (NTpro-BNP) and high sensitivity cardiac troponin T (hs-cTnT) may be associated with dementia. However, limited data exist on their association with either pre-dementia stages, that is, cognitive impairment no dementia (CIND), or the burden of cerebrovascular diseases (CeVD).We therefore, examined the association of these biomarkers of cardiac dysfunction with CeVD in both CIND and dementia.A case-control study, with cases recruited from memory clinics and controls from memory clinics and community. All subjects underwent collection of blood samples, neuropsychological assessment, and neuroimaging. Subjects were classified as CIND and dementia based on clinical criteria whilst significant CeVD was defined as the presence of cortical infarcts and/or more than 2 lacunes and/or confluent white matter lesions in two regions of brain on Age-Related White Matter Changes Scale.We included a total of 35 controls (mean age: 65.9 years), 78 CIND (mean age: 70.2 years) and 80 cases with dementia (mean age: 75.6 years). Plasma concentrations of hs-cTnT were associated significantly with CeVD in both CIND (odds ratios [OR]: 9.05; 95% confidence interval [CI]: 1.64-49.79) and dementia (OR: 16.89; 95%CI: 2.02-142.67). In addition, NTpro-BNP was associated with dementia with CeVD (OR: 7.74; 95%CI: 1.23-48.58). These associations were independent of other vascular risk factors.In this study, we showed that plasma NTproBNP and hs-cTnT are associated with dementia and CIND, only when accompanied by presence of CeVD.

    2017-01-01

    Background The majority of people with dementia have other long-term diseases, the presence of which may affect the progression and management of dementia. This study aimed to identify subgroups with higher healthcare needs, by analysing how primary care consultations, number of prescriptions and hospital admissions by people with dementia varies with having additional long-term diseases (comorbidity). Methods A retrospective cohort study based on health data from the Clinical Practice Research Datalink (CPRD) was conducted. Incident cases of dementia diagnosed in the year starting 1/3/2008 were selected and followed for up to 5 years. The number of comorbidities was obtained from a set of 34 chronic health conditions. Service usage (primary care consultations, hospitalisations and prescriptions) and time-to-death were determined during follow-up. Multilevel negative binomial regression and Cox regression, adjusted for age and gender, were used to model differences in service usage and death between differing numbers of comorbidities. Results Data from 4999 people (14 866 person-years of follow-up) were analysed. Overall, 91.7% of people had 1 or more additional comorbidities. Compared with those with 2 or 3 comorbidities, people with ≥6 comorbidities had higher rates of primary care consultations (rate ratio (RR) 1.31, 95% CI 1.25 to 1.36), prescriptions (RR 1.68, 95% CI 1.57 to 1.81), and hospitalisation (RR 1.62, 95% CI 1.44 to 1.83), and higher risk of death (HR 1.56, 95% CI 1.37 to 1.78). Discussion In the UK, people with dementia with higher numbers of comorbidities die earlier and have considerably higher health service usage in terms of primary care consultations, hospital admissions and prescribing. This study provides strong evidence that comorbidity is a key factor that should be considered when allocating resources and planning care for people with dementia. PMID:28279992

    Zeilig, Hannah

    2014-04-01

    This article contributes to debates about the category "dementia," which until recently has been dominated by biomedical models. The perspectives of critical gerontology are pertinent for extending knowledge about dementia and guiding this analysis. These perspectives encourage examination of cultural and historical influences and thus question how societies have constructed and defined dementia. This article queries the stories told about dementia and the language that we use to tell these stories. Central to the article is an analysis of some of the stories about dementia that are contained within and framed by contemporary culture. A number of films, TV documentaries, news reports, theatre, memoirs, novels, and poems that portray some of the experiences associated with dementia are interrogated. These representations are examined as they either perpetrate or challenge stereotypes about living with dementia. Analysis of these representations demonstrates the sociocultural construction of dementia and the extent to which dementia is a diachronic phenomenon. Above all, the article considers (a) the social and political dimensions of dementia, (b) the ways in which the metaphors persistently used to explain dementia shape our consciousness about this condition, and (c) the extent to which dementia is an inherent part of contemporary life.

    The study of psychiatric manifestations in dementia has long been overshadowed by the more classical manifestations of the disease, such as memory loss and other cognitive deficits. In recent years, however, psychiatric symptoms as part of the demential process have attracted interest and research has become more specific. Clinicians are faced with diagnostic, treatment and management difficulties related to affective or psychotic symptoms, which account for much distress and morbidity. Several studies indicate that the prevalence of psychiatric manifestations in clinical populations of patients suffering from dementia is high: 15% to 30% for hallucinations, 15% to 30% for delusions, ten percent to 20% for major depression and 40% to 50% for depressed mood. These figures tend to confirm the hypothesis that psychiatric features in dementia are neither infrequent nor atypical. Thus, researchers have sought to link psychotic or depressive symptomatology with several clinical characteristics of dementia, namely stage, severity, prognosis or cognitive dysfunction. Some recent studies involving extensive neuropsychological evaluations indicate that subgroups of patients can be defined according to psychiatric criteria, as well as cognitive or neurological criteria. Unfortunately, results are inconsistent. Some of the contradictions in the literature are related to poorly defined terms and symptoms, a lack of reliable operational criteria, absence of validation of instruments and scales and heterogeneity of the populations studied. Ambiguous syndromes, such as pseudodementia, while illustrative of certain clinical situations, have not been helpful in categorizing demented patients. The author suggests that research focused on specific and clearly defined psychiatric symptoms in dementia will better serve our comprehension of mixed syndromes.

    Full Text Available Vascular dementia (VaD is the second most frequent dementia after Alzheimer’s disease, and is diagnosed during lifetime in 20% of demented patients. Five­year survival rate in VaD is 39%, while it is estimated to be 75% in healthy persons of the same age. It is therefore important to make correct diagnosis of VaD early in the course of the disease. Risk factors for VaD are identical to stroke risk factors, and there are significant possibilities for the prevention of vascular cognitive decline. Cognitive decline develops acutely or step­by­step within three months after stroke, but more gradual progression of intellectual decline is also possible. Neurological examination can reveal pyramidal and extrapyramidal signs, pseudobulbar palsy, gait disturbance and urinary incontinence. Neuropsychological profile comprises the loss of cognitive set shifting, decline in word fluency, verbal learning difficulties, perseverations, difficulties in complex figure copying, and in patients with cortically located lesions also problems with speech and praxia. The basis of the diagnosis is, besides history, neurological examination and neuropsychological assessment, computed tomography and/ or magnetic resonance brain imaging. Vascular risk factors control is the most important measure in VaD prevention. Modern guidelines for the treatment of cognitive decline in VaD emphasize that donepezil can be useful in the improvement of cognitive status at the level of Class IIa recommendation at the level of evidence A, while memantine may be useful in patients with mixed VaD and Alzheimer’s disease dementia.

    There are multiple diagnostic criteria for vascular dementia (VaD) that may define different populations. Utilizing the criteria of the National Institute of Neurological Disorders and Stroke and Association Internationale pour la Recherche et l'Enseignement en Neurosciences (NINDS-AIREN) has provided improved consistency in the diagnosis of VaD. The criteria include a table listing brain imaging lesions associated with VaD. The different neuroradiological aspects of the criteria are reviewed based on the imaging data from an ongoing large-scale clinical trial testing a new treatment for VaD. The NINDS-AIREN criteria were applied by a centralized imaging rater to determine eligibility for enrollment in 1,202 patients using brain CT or MRI. Based on the above data set, the neuroradiological features that are associated with VaD and that can result from cerebral small-vessel disease with extensive leukoencephalopathy or lacunae (basal ganglia or frontal white matter), or may be the consequence of single strategically located infarcts or multiple infarcts in large-vessel territories, are illustrated. These features may also be the consequence of global cerebral hypoperfusion, intracerebral hemorrhage, or other mechanisms such as genetically determined arteriopathies. Neuroimaging confirmation of cerebrovascular disease in VaD provides information about the topography and severity of vascular lesions. Neuroimaging may also assist with the differential diagnosis of dementia associated with normal pressure hydrocephalus, chronic subdural hematoma, arteriovenous malformation or tumoral diseases.

    Interest of brain single-photon emission computed tomography to support clinical diagnosis of Alzheimer-type dementia is now established. Numerous studies have reported a decreased perfusion in the association cortex of the parietal lobe and the posterior temporal regions. In patients with mild cognitive complaints, the presence of focal hypoperfusion may increase substantially the probability of the disease. In addition, emission tomography emerges as a helpful tool in situation in which there is diagnostic doubt. In this case, the presence of temporo-parietal perfusion deficit associated with hippocampal atrophy on MRI or X-ray computed tomography contributes to diagnostic accuracy. However, some studies suggest that emission tomography may be useful for preclinical prediction of Alzheimer's disease and to predict cognitive decline. (author)

    As the aging society with low birth rate progresses, the burden of care for the dementia elderly increases. Thus, an increasing attention has been paid to the epidemiology of dementia in Japan. This phenomenon is also observed in many developing countries all over the world. In this paper, the author reports the prevalence of dementia among the elderly people aged 65 years and older in Japan using the data from a recent nation-wide survey. According to the results of this survey which was conducted at seven sites in Japan, the prevalence rate was estimated to be 15.75% (95% CI: 12.4-22.2%) which was much higher than that had been estimated before. Alzheimer disease is the most common illness that causes dementia, and followed by vascular dementia and Lewy body dementia. As the limitation of this nation-wide survey, no study was conducted in urban area with low percentage of elderly in a population. Thus, additional studies are ongoing into the prevalence of dementia in urban areas.

    Several cognitive impairment/dementia diagnostic methods were examined concerning their results: (a) in the differentiation of accidental and pathological ability changes; (b) in the demonstration/exclusion of cognitive impairment; and (c) the degree of dementia. Sixty-five patients suffering from brain damage were examined with five accepted methods of diagnosing dementia (Syndrom-kurztest, KAI-MWT-Methode, Demenz-Test, Mini-Mental-Status-Test, Wurzer-Methode) and a comprehensive performance test battery as an external criterion for valid determination of the degree of dementia and definite differentiation of accidental and pathological performance changes. The five methods of diagnosing dementia differ appreciably in determining the degree of severity (r = 0.44). They are effective in registering accidental performance changes in comparison with the outer criterion, but pathological changes are inaccurately registered (hit rate 88%/53%); the results concerning the degree of cognitive impairment are identical: between 25 and 43% (r = 0.43). High rates (58%) of false-negative diagnoses are especially apparent in the range of slight and intermediate cognitive impairment. The methods examined are only useful for the demonstration and not for the exclusion of severe cognitive impairment (dementia) and in no circumstances for the registration of slight/intermediate cognitive impairment. Valid diagnosis of cognitive impairment/dementia necessitates the use of test batteries that differentiate functions including the premorbid performance level.

    Montessori-based Dementia Care is an approach used in Alzheimer's care that does not involve chemical or physical restraints. This program works by giving the elder with Alzheimer/Dementia a purpose by getting them involved. When staff/families care for a confused Alzheimer/Dementia patient, who is having behaviors, the Montessori program teaches them to look at what is causing the behavior. When assessing the elder to determine what is causing the behavior, the goal is to find the answer, but the answer cannot be dementia. The goal of the program is to bring meaning to the life of an Alzheimer/Dementia elder.

    A decade of genetic counseling of frontotemporal dementia (FTD) affected families has generated two important observations. First, the uptake rate for presymptomatic testing for FTD is low in our department of Clinical Genetics at the Erasmus Medical Center in the Netherlands. Second, FTD at-risk counselees reported substantial familial opposition to genetic testing, which is distinct from the attitude in Huntington Disease affected families. We hypothesize that the low acceptance for FTD gen...

We aimed to investigate the difference between AD, subcortical vascular dementia (SVaD and mild cognitive impairment (MCI patients by means of ideomotor limb apraxia frequency and severity. Ninety-six AD, 72 SVaD, and 84 MCI patients were assessed with the mini-mental status examination (MMSE, clinical dementia rating (CDR and the apraxia screening test of TULIA (AST. Apraxia was significantly more frequent in the AD patients (32.3% than in both of the SVaD (16.7% and MCI (4.8% patients. The frequency of apraxia was also significantly higher in SVaD patients than in MCI patients. AD patients had significantly lower apraxia scores than both SVaD and MCI patients. In addition, a significant difference was found between SVaD and MCI patients in terms of apraxia scores. These results suggest that the widespread belief of the association between apraxia and cortical dementias is not exactly correct. The significant difference between both of the dementia groups and the MCI patients suggests that the absence of apraxia can be an indicator for MCI diagnosis.Keywords: apraxia, Alzheimer’s disease, subcortical vascular dementia, mild cognitive impairment

    2012-08-01

    In these last years, creativity was found to play an important role for dementia patients in terms of diagnosis and rehabilitation strategies. This led us to explore the relationships between dementia and creativity. At the aim, artistic creativity and divergent thinking are considered both in non-artists and artists affected by different types of dementia. In general, artistic creativity can be expressed in exceptional cases both in Alzheimer's disease and Frontotemporal dementia, whereas divergent thinking decreases in dementia. The creation of paintings or music is anyway important for expressing emotions and well-being. Yet, creativity seems to emerge when the right prefrontal cortex, posterior temporal, and parietal areas are relatively intact, whereas it declines when these areas are damaged. However, enhanced creativity in dementia is not confirmed by controlled studies conducted in non-artists, and whether artists with dementia can show creativity has to be fully addressed. Future research directions are suggested.

    Managing patients with dementia requires a practitioner to exercise diverse skills. Communicating with the patient (as their dementia allows), relatives, caregivers and medical personnel are essential elements in the care process. Diagnosis of oral health problems may not be straightforward, clinical examination and treatment planning may be hampered by poor cooperation from the person with dementia. Practitioners must view any treatment from the patient's perspective and balance this with the requirements for sound clinical care. The consent process must be approached in a manner that fulfils the ethical responsibilities that acknowledge patient rights. This can be difficult when managing a patient with dementia. This paper will explore issues surrounding the consent process and the provision of oral health care to people suffering from dementia. It is hoped that readers will be stimulated to review their practice; especially related to informed consent, whether they routinely manage patients with dementia or not. Such practice evaluation should consider the wants and needs of patients and families on a broader than clinical basis and thus enhance the care that is brought to this group of interesting and often challenging patients.

    2013-01-01

    Dementia and bipolar disorder have been traditionally considered two separate clinical entities. However, recent preclinical and clinical data in elderly people suggest that they are in fact related. Several theories have been put forward to interpret their relationship which could be summed up as follows: (1) Dementia could increase the risk for the emergence of bipolar symptoms, or (2) conversely, bipolar disorder might be associated with heightened risk for developing pseudodementia or dementia. (3) Alternatively, dementia, other brain diseases or drugs affecting brain function could lead to the combination of symptoms of dementia and bipolar disorder in elderly individuals. The two disorders demonstrate similarities with respect to their clinical expression (agitation, psychotic, mood and cognitive symptoms) and structural brain neuroimaging (enlarged lateral ventricles and white matter hyperintensities using magnetic resonance imaging-MRI). Despite the above similarities, the two disorders also have important differences. As expected, cognitive symptoms prevail in dementia and mood symptoms in bipolar disorder. In dementia but not in bipolar disorder there is evidence that brain structural abnormalities are diffuse and hippocampal volumes are smaller. Dementia and bipolar disorder present different abnormalities in functional brain neuroimaging. The pattern of "ventral" hyperactivity and "dorsal" hypoactivity in brain emotional circuits at rest is revealed in bipolar disorder but not dementia. With respect to their treatment, acetylcholinesterase inhibitors and memantine are indicated against cognitive symptoms in dementia and also improve behavioural and psychological symptoms appearing during the course of dementia. Lithium, anticonvulsants, antipsychotics and antidepressants are effective in the management of the acute episodes of bipolar disorder of younger adults, but there are not yet evidence-based data in elderly bipolar patients. It is likely that the

    2011-03-01

    The use of nonliteral language in clinical assessment, especially testing the patients' ability to interpret proverbs, has a long tradition in psychiatry. However, its diagnostic sensitivity and specificity in dementias is not yet clear. The aim of this review article is to examine the current evidence on nonliteral/figurative language (proverb, metaphor, metonymy, idiom, irony, sarcasm) comprehension in Alzheimer's disease and related disorders. A comprehensive literature search identified 25 studies (16 proverb, 3 metaphor, 0 metonymy, 5 idiom, 3 sarcasm) on nonliteral language comprehension in dementia. Studies predominantly indicate a deficit. Most studies investigated Alzheimer's dementia. Applied correctly, nonliteral language is a worthwhile diagnostic tool to evaluate language and abstract thinking in dementias. During assessment, familiarity testing (e.g., by asking "are you familiar with the proverb XY") is obligatory. Still, future research is needed in several areas: evidence on decline of nonliteral language over the course of the illness is limited. So far, almost no studies delineated proverb comprehension in high risk populations such as patients with mild cognitive impairment. Currently, there is a lack of studies addressing performance in direct comparison to relevant differential diagnosis like older-age depression, delirium, brain lesion, or other psychiatric conditions.

    Full Text Available Abstract Aim To describe the development of a dementia research registry, outlining the conceptual, practical and ethical challenges, and to report initial experiences of recruiting people with dementia to it from primary and secondary care. Background Women, the oldest old and ethnic minorities have been under-represented in clinical trials in dementia. Such under-representation biases estimates of absolute effect, absolute harm and cost-effectiveness. Research on dementia should include patient populations that more exactly reflect the population at risk. One of the impediments to this is the lack of a suitable tool for identification of patients suitable for studies. Construction & contents A technology development methodology was used to develop a registry of people with dementia and their carers. This involved phases of modelling and prototype creation, 'bench testing' the prototype with experts and then 'field testing' the refined prototype in exemplar sites. The evaluation of the field testing described here is based on a case study methodology. Utility This case study suggests that construction and population of a dementia research registry is feasible, but initial development is complex because of the ethical and organisational difficulties. Recruitment from primary care is particularly costly in terms of staff time and only identifies a very small number of people with dementia who were not already known to specialist services. Recruiting people with dementia through secondary care is a resource intensive process that takes up to six months to complete. Identifying the components of a minimum dataset was easy but its usefulness for pre-screening potential research populations has yet to be established. Acceptance rates are very high in the first clinic to recruit to the registry, but this may reflect the efforts of registry 'champions'. Discussion and Conclusions Easier recruitment may perpetuate potential selection biases and we are

However, the included trials were generally low in quality. More well-designed, high-quality trials are needed to provide better evidence for the assessment of the efficacy and safety of Chinese medicines for vascular dementia.

    2016-03-01

    Full Text Available Objective: In 2015, the Centers for Medicare and Medicaid Services (CMS released new summary star ratings for US hospitals based on patient experience. We aimed to test the association between CMS patient experience star ratings and clinical outcomes. Methods: We analyzed risk-adjusted data for more than 3000 US hospitals from CMS Hospital Compare using linear regression. Results: We found that better patient experience was associated with favorable clinical outcomes. Specifically, a higher number of stars for patient experience had a statistically significant association with lower rates of many in-hospital complications. A higher patient experience star rating also had a statistically significant association with lower rates of unplanned readmissions to the hospital within 30 days. Conclusion: Better patient experience according to the CMS star ratings is associated with favorable clinical outcomes. These results support the inclusion of patient experience data in the framework of how hospitals are paid for services.

    Full Text Available Dementia and Diabetes mellitus (DM are major health problems nowadays. DM leads to a significant cognitive decline and increases the risk of dementia, mostly Alzheimer's Disease (AD and vascular dementia (VaD by 50-100% and 100-150%, respectively. Amyloid beta (Abeta, the main pathogenic factor in AD development, is eliminated by advanced glycation end products (AGEs and degraded by insulin degrading enzyme (IDE for which it competes with insulin. Insulin stimulates secretion of Abeta and promotes brain inflammation. DM I and II cause slowing down of mental speed, lowering of mental flexibility and DM II learning and memory disturbances. DM acts both directly by hyperglycaemia and hyperinsulinaemia and by the blood vessel changes. Hyperglycaemia changes synapse plasticity and leads to cognitive decline. AGEs disrupt the neuron function and bonding to Abeta increases its aggregability. Glycation of tau protein promotes production of neurofibrillary tangles (NFT, the main intracellular pathogenic factor in AD. AGE2 in DM causes pathological angiogenesis and apoptosis of neurons. AGE receptor (RAGE is also the specific Abeta receptor with which it produces reactive oxygen species that has, as a result, disruption of mitochondrial function and reduction of neuronal energy resources. Insulinoresistance is linked with the dysexecutive syndrome, and hyperinsulinaemia increases the risk of AD especially by enhancing phosphorylation of tau protein and formation of NFT. Application of insulin showed improvement of memory, behaviour and affect in AD patients. Good glycoregulation emerged as an important factor in dementia prevention, and a better insight in relations of DM and brain function will lead to new potential dementia therapies. .

Breakdown in default networking is one of the early dysfunction in cortical dementias and result in perplexity, awkwardness, omission, substitution errors, toying behavior and unrecognizable gestures in response to command with voluntary reflex dissociation where, when unobserved patient will carry out reflex movements normally. Awareness into the organicity of these phenomenas will help in early diagnosis, which will help in initiating appropriate treatment and slowing down the progression of the disease. Aims and Objectives: The aim was to look for the various kinds of apraxias in patients with dementia using appropriate simple tests. Patients and Methods: Three hundred patients satisfying Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition criteria for dementia were evaluated in detail with mandatory investigations for dementia followed by testing for ideational, ideomotor, limb-kinetic, buccopharyngeal, dressing apraxia, constructional apraxia and gait apraxias in addition to recording of rare apraxias when present. Results: Alzheimer′s disease showed maximum association with apraxias in all the phases of the disease ideational, ideomotor, dressing and constructional apraxias early and buccopharyngeal and gait apraxia late. Frontotemporal lobe dementia showed buccopharyngeal and gait apraxias late into the disease. Cortical basal ganglionic degeneration showed limb apraxias and diffuse Lewy body disease showed more agnosias and less apraxias common apraxias seen was Ideational and Ideomotor. Conclusion: Recognition of the apraxias help in establishing organicity, categorization, caregiver education, early strategies for treatment, avoiding anti-psychotics and introducing disease modifying pharmacotherapeutic agents and also prognosticating.

    Despite much recent interest in music and dementia, music perception has not been widely studied across dementia syndromes using an information processing approach. Here we addressed this issue in a cohort of 30 patients representing major dementia syndromes of typical Alzheimer’s disease (AD, n=16), logopenic aphasia (LPA, an Alzheimer variant syndrome; n=5) and progressive nonfluent aphasia (PNFA; n=9) in relation to 19 healthy age-matched individuals. We designed a novel neuropsychological battery to assess perception of musical patterns in the dimensions of pitch and temporal information (requiring detection of notes that deviated from the established pattern based on local or global sequence features) and musical scene analysis (requiring detection of a familiar tune within polyphonic harmony). Performance on these tests was referenced to generic auditory (timbral) deviance detection and recognition of familiar tunes and adjusted for general auditory working memory performance. Relative to healthy controls, patients with AD and LPA had group-level deficits of global pitch (melody contour) processing while patients with PNFA as a group had deficits of local (interval) as well as global pitch processing. There was substantial individual variation within syndromic groups. No specific deficits of musical temporal processing, timbre processing, musical scene analysis or tune recognition were identified. The findings suggest that particular aspects of music perception such as pitch pattern analysis may open a window on the processing of information streams in major dementia syndromes. The potential selectivity of musical deficits for particular dementia syndromes and particular dimensions of processing warrants further systematic investigation. PMID:27802226

    Full Text Available Abstract Background and purpose Placebo response rates in clinical trials vary considerably and are observed frequently. For new drugs it can be difficult to prove effectiveness superior to placebo. It is unclear what contributes to improvement in the placebo groups. We wanted to clarify, what elements of clinical trials determine placebo variability. Methods We analysed a representative sample of 141 published long-term trials (randomized, double-blind, placebo-controlled; duration > 12 weeks to find out what study characteristics predict placebo response rates in various diseases. Correlational and regression analyses with study characteristics and placebo response rates were carried out. Results We found a high and significant correlation between placebo and treatment response rate across diseases (r = .78; p Conclusion Medication response rates and placebo response rates in clinical trials are highly correlated. Trial characteristics can explain some portion of the variance in placebo healing rates in RCTs. Placebo response in trials is only partially due to methodological artefacts and only partially dependent on the diagnoses treated.

  3. A Review of Behavioural Gerontology and Dementia Related Interventions

    Directory of Open Access Journals (Sweden)

    Josling, Megan

    2015-12-01

    Full Text Available Behavioural Gerontology is concerned with the interaction of the aging individual and their environment. One aspect of behavioural gerontology has focussed on the use of behaviourist methods to improve the functioning and quality of life of individuals with dementia. Positive reinforcement techniques have shown to have an effect on dementia related behavioural excesses (wandering, disruptive vocalisations, behavioural deficits (incontinence, self feeding and mood changes (depression. One of the major concerns of using reinforcement techniques in the case of dementia is maintenance of the behavioural changes with the continual implementation of the intervention. Research has indicated that individuals with dementia meet behavioural extinction criteria at an advanced rate in comparison with individuals without dementia. Thus for a behavioural change to be successfully maintained it requires diligence on the part of the caregiver and/or nursing home staff. In the case of dementia care centres and nursing homes, when using behavioural interventions to modify the behavioural symptoms of dementia, there needs to be a considerable overlap between Behavioural Gerontology and Organisational Behavioural Management to ensure the successful maintenance of behavioural change.

  4. Rising midlife obesity will worsen future prevalence of dementia.

    Binod Nepal

    Full Text Available Midlife body weight status has been found to affect late life dementia outcomes. A cohort projections model was developed to assess the impact of midlife body mass index (BMI profile on dementia in older Australians.A baseline projection using age-sex specific dementia prevalence rates was constructed and the results of scenarios that took account of midlife BMI were compared with those from population ageing only.This modelling predicts that if the rising trend in midlife obesity and declining trend in midlife normal weight in Australia are to be taken into account in projecting future numbers of Australians with dementia then the number of people aged 65 or more years with dementia, by 2050, would be 14% higher than that expected from demographic ageing only. If midlife obesity prevalence was decreased to 20% and normal weight increased to 40% over the period of 2015-2025, then dementia cases among persons aged 65-69 years would be lower by about 10% in 2050 compared with the "doing nothing to stop current trends in obesity" projection.The rising tide of obesity in Australian adults will increase the dementia epidemic expected in future years.

    Background. GPs and patients are frequently asked to evaluate mental health care, but studies including evaluations from both groups are rare. Objective. To assess the association between GPs' and patients' assessment of mental health outpatient clinic in Norway and identify important health care predictors for patient and GP satisfaction with the clinics. Methods. Two cross-sectional national surveys were carried out: survey of GPs in 2006 and patients in 2007 evaluating outpatient clinics at 69 community mental health centres in Norway. A total of 2009 GPs and 9001 outpatients assessed the clinics by means of a postal questionnaire. Main outcome measures were correlations between GP and patient ratings of the outpatient clinics at the clinic level and health care predictors for patient satisfaction and GP satisfaction with the clinics. Results. Clinic scores for GPs' and patients' assessment of waiting time were moderate to highly correlated (0.65), while clinic scores for GP and patient satisfaction had a lower but significant positive association (0.37). Significant positive correlations between clinic scores for GP and patients ratings were found for 38 of the 48 associations tested. The most important predictors for patient satisfaction with the clinics were interaction with the clinician (beta: 0.23) and being met with politeness and respect at the clinic (beta: 0.19), while the most important predictors for GP satisfaction with the clinics were perceived competence (beta: 0.25), rejection of referrals (beta: −0.17) and waiting time for patients (beta: −0.16). Conclusions. A consistent positive association between GP and patient ratings at the clinic level was identified. Mental health services aiming at improving GP and patient satisfaction should be sensitive to the fact that the two groups prioritize different health care factors. PMID:19584122

    Although several surveys have been conducted around the world, few surveys have investigated the prevalence of dementia in Latin America. The aim of this study was to estimate dementia prevalence in a community sample in Ribeirão Preto, Brazil, and to evaluate its distribution across several socio-demographic and clinical characteristics and habits. The population was aged 60 years and older and a representative sample from three different social regions. The screening instruments used in the first phase were the Mini-Mental State Examination, the Fuld Object-Memory Evaluation, the Informant Questionnaire on Cognitive Decline in the Elderly, and the Bayer Activities of Daily Living Scale. In the second phase, the Cambridge Examination was employed to diagnose dementia according to the DSM-IV criteria. The estimate of dementia prevalence was adjusted for screening instrument performance, using the positive and negative predictive values. The data were weighted to compare frequencies, considering the sampling and the non-response effect, and subjected to multivariate analysis. In all, 1.145 elderly subjects were evaluated (mean age: 70.9 years), of whom 63.4% were female and 52.8% had up to 4 years of schooling (participation rates at the first and the second phases were 62.6 and 60%, respectively). The observed and estimated prevalences of dementia were 5.9% and 12.5%, respectively (n = 68). Alzheimer's disease was the main cause (60.3%). Dementia was associated with old age, low education, stroke, absence of arthritis, and not reading books. The estimated prevalence of dementia was higher than the prevalence previously found. Associated factors confirmed the importance of intellectual activities in prevention.

    Patients with dementias commonly experience neuropsychiatric symptoms that diminish their quality of life. Pharmacologic treatments for these symptoms are limited in their efficacy. In the absence of near-future prospects for a cure for degenerative dementias, treatments that improve neuropsychiatric symptoms and quality of life are needed. We explore the hypothesis that art therapy is useful in dementia by reviewing the extant literature. With appropriate structure, patients with dementia can produce and appreciate visual art. Case studies and several small trials suggest that art therapy engages attention, provides pleasure, and improves neuropsychiatric symptoms, social behavior, and self-esteem. Whether these benefits generalize beyond the studio remains unknown. We offer a theoretical framework that motivates the use of art therapy and propose that clinical enquiry to establish methods, assess efficacy, and define optimal conditions for the use of art therapy in Alzheimer's and other dementing disorders is timely.

    The legal competency or capability to exercise rights is level of judgment and decision-making ability needed to manage one's own affairs and to sign official documents. With some exceptions, the person entitles this right in age of majority. It is acquired without legal procedures, however the annulment of legal capacity requires a juristic process. This resolution may not be final and could be revoked thorough the procedure of reverting legal capacity - fully or partially. Given the increasing number of persons with dementia, they are often subjects of legal expertise concerning their legal capacity. On the other part, emphasis on the civil rights of mentally ill also demands their maximal protection. Therefore such distinctive issue is approached with particular attention. The approach in determination of legal competency is more focused on gradation of it's particular aspects instead of existing dual concept: legally capable - legally incapable. The main assumption represents how person with dementia is legally capable and should enjoy all the rights, privileges and obligations as other citizens do. The aspects of legal competency for which person with dementia is going to be deprived, due to protection of one's rights and interests, are determined in legal procedure and then passed over to the guardian decided by court. Partial annulment of legal competency is measure applied when there is even one existing aspect of preserved legal capability (pension disposition, salary or pension disposition, ability of concluding contract, making testament, concluding marriage, divorce, choosing whereabouts, independent living, right to vote, right to decide course of treatment ect.). This measure is most often in favour of the patient and rarely for protection of other persons and their interests. Physicians are expected to precisely describe early dementia symptoms which may influence assessment of specific aspects involved in legal capacity (memory loss, impaired task

    Mark E Larsen

    Full Text Available Identifying cognitively healthy people at high risk of developing dementia is an ever-increasing focus. These individuals are essential for inclusion in observational studies into the natural history of the prodromal and early disease stages and for interventional studies aimed at prevention or disease modification. The success of this research is dependent on having access to a well characterised, representative and sufficiently large population of individuals. Access to such a population remains challenging as clinical research has, historically, focussed on patients with dementia referred to secondary and tertiary services. The primary care system in the United Kingdom allows access to a true prodromal population prior to symptoms emerging and specialist referral. We report the development and recruitment rates of the CHARIOT register, a primary care-based recruitment register for research into the prevention of dementia. The CHARIOT register was designed specifically to support recruitment into observational natural history studies of pre-symptomatic or prodromal dementia stages, and primary or secondary prevention pharmaceutical trials or other prevention strategies for dementia and other cognitive problems associated with ageing.Participants were recruited through searches of general practice lists across the west and central London regions. Invitations were posted to individuals aged between 60 and 85 years, without a diagnosis of dementia. Upon consent, a minimum data set of demographic and contact details was extracted from the patient's electronic health record.To date, 123 surgeries participated in the register, recruiting a total of 24,509 participants-a response rate of 22.3%. The age, gender and ethnicity profiles of participants closely match that of the overall eligible population. Higher response rates tended to be associated with larger practices (r = 0.34, practices with a larger older population (r = 0.27, less

    We report results of Iotrolan CT-cisternography on 41 demented patients (13 males and 28 females) to find 'occult normal pressure hydrocephalus'. These patients were suspected to have CSF flow disturbance from clinical symptoms and simple brain CT scan findings. Their average age, duration of dementia, and score of Hasegawa's dementia scale (HDS) were 76.2 years, 5.9 years, 9.5/32.5,respectively. Before performing CT-cisternography, clinical diagnosis for their dementia were vascular dementia in 18 patients. Alzheimer type dementia in 12, suspect of NPH in 5, and other diagnoses in 6. From the results of cisternography, we found 13 patients with CSF flow disturbance (contrast material remained in the ventricle more than 48 hours after injection), and 17 patients with normal CSF flow. The former showed lower scores of HDS, higher urinary incontinence scores and smaller areas of the interhemispheric fissure on CT scan than the latter. But the former showed no significant difference from the latter in the average age, duration of dementia and width of the ventricles. (author).

    Aging associated brain decline often result in some kind of dementia. Even when this is a complex brain disorder a physical model can be used in order to describe its general behavior. A probabilistic model for the development of dementia is obtained and fitted to some experimental data obtained from the Alzheimer's Disease Neuroimaging Initiative. It is explained how dementia appears as a consequence of aging and why it is irreversible.

    2006-01-01

    OBJECTTVE: To explain the association between vascular dementia and the cranial MRI manifestations, and recognize the value of cranial MRI in the early diagnosis of vascular dementia and the assessment of disease conditions.DATA SOURCES: Pubmed database was searched to identify articles about the cranial MRI manifestations of patients with vascular dementia published in English from January 1992 to June 2006 by using the key words of "MRI, vascular dementia". Others were collected by searching the name of journals and title of articles in the Chinese full-text journal database.STUDY SELECTTON: The collected articles were primarily checked, those correlated with the cranial MRI manifestations of patients with vascular dementia were selected, while the obviously irrelative ones were excluded, and the rest were retrieved manually, the full-texts were searched.DATA EXTRACTION: Totally 255 articles were collected, 41 of them were involved, and the other 214 were excluded.DATA SYNTHESIS: MRI can be taken as one of the effective methods for the early diagnosis and disease evaluation of vascular dementia. White matter lesions are the important risk factors of vascular dementia.Vascular dementia is accompanied by the atrophy of related brain sites, but further confirmation is needed to investigate whether there is significant difference. MRI can be used to quantitatively investigate the infarcted sites and sizes of patients with vascular dementia after infarction, but there is still lack of systematic investigation on the association of the infarcted sites and sizes with the cognitive function of patients with vascular dementia.CONCLUSTON: Cranial MRI can detect the symptoms of vascular dementia at early period, so that corresponding measures can be adopted to prevent and treat vascular dementia in time.

    Full Text Available Background/Aims: The purpose of our study was to evaluate vascular risk factors and other clinical variables as predictors of cognitive and functional decline in elderly patients with mild to moderate dementia. Methods: The clinical characteristics of 82 elderly patients (mean age 79.0 ± 5.9 years; 67.1% females with mild to moderate dementia were obtained at baseline, including years of education, Framingham Coronary Heart Disease Risk score, Hachinski Ischemic Score (HIS, Clinical Dementia Rating (CDR, Mini-Mental State Examination (MMSE score, Functional Activities Questionnaire (FAQ score, Burden Interview Scale score, and Neuropsychiatric Inventory (NPI score. Changes in MMSE and FAQ scores over time were assessed annually. The association between baseline clinical variables and cognitive and functional decline was investigated during 3 years of follow-up through the use of generalized linear mixed effects models. Results: A trend was found towards steeper cognitive decline in patients with less vascular burden according to the HIS (β = 0.056, p = 0.09, better cognitive performance according to the CDR score (β = 0.313, p = 0.06 and worse caregiver burden according to the Burden Interview Scale score (β = -0.012, p = 0.07 at baseline. Conclusion: Further studies with larger samples are necessary to confirm and expand our findings.

    Patients suffering from dementia are nevertheless still able to render exceptional musical performances. For example, they can recognize music from childhood and reproduce lyrics and melodies of songs with four verses. Furthermore, behavioural symptoms such as psycho- motor agitation and crying, but also aggressive behaviour can be positively influenced by music and motivation and positive emotions can be increased. A variety of physiological and psychological changes occur when patients are listening to music. Previous research could show that music activated different parts of the brain especially in the temporal cortex, but also motoric areas in the frontal cortex, thalamus and cerebellum were essential for rhythm, melody and harmony perception and processing. Music therapy is an interpersonal process in which music is used within a therapeutic relationship to address physical, emotional, cognitive, and social needs of individuals with various psychiatric or medical conditions. However, until now only little research has been directed towards non-pharmacological treatments like music therapy in dementia patients. Further research is warranted to investigate the long term influence of music therapy on patients suffering from dementia.

  4. Does wine prevent dementia?

    Full Text Available Roger M PinderPharma Consultant, York, UKAbstract: There is substantial evidence that moderate consumption of alcohol reduces significantly the risks of coronary heart disease, stroke and type 2 diabetes. Furthermore, the incidence of dementia, both of the Alzheimer’s type (AD and the vascular variety (VaD, is lower in societies which consume a Mediterranean diet of mainly fish, fruit, vegetables, olive oil, and wine. In particular, extensive evidence from both population-based cohort and case control studies in different areas of the world and across genders and racial groups suggests that regular consumption of moderate amounts of alcohol, especially in the form of wine, is associated with a lower risk of developing AD and VaD compared with abstention and heavy drinking. Carriers of the APOE ε4 allele seem to gain less benefit. Age-related cognitive decline, particularly in women, is lower in regular drinkers, while older drinkers with Mild Cognitive Impairment (MCI progress less frequently to AD than their abstaining counterparts. Plausible biological mechanisms for the neuroprotective effects of wine include its glucose-modifying, antioxidant and inflammatory properties, but it additionally seems to modify the neuropathology of AD, particularly the deposition of amyloid plaque. Indeed, some of these mechanisms are already targets for the development of new therapeutic agents for the treatment of dementia.Keywords: alcohol, Alzheimer’s disease, dementia, epidemiology, polyphenols, wine

    Sleep disturbance is prevalent in older adults, particularly so in those at a greater risk of dementia. However, so far the clinical, medical and neuropsychological correlates of daytime sleep have not been examined. The aims of this study were to investigate the characteristics and effects of napping using actigraphy in older people, particularly in those 'at risk' of dementia. The study used actigraphy and sleep diaries to measure napping habits in 133 older adults 'at risk' of dementia (mean age = 65.5 years, SD = 8.4 years), who also underwent comprehensive medical, psychiatric and neuropsychological assessment. When defined by actigraphy, napping was present in 83.5% (111/133) of participants; however, duration and timing varied significantly among subjects. Nappers had significantly greater medical burden and body mass index, and higher rates of mild cognitive impairment. Longer and more frequent naps were associated with poorer cognitive functioning, as well as higher levels of depressive symptoms, while the timing of naps was associated with poorer nocturnal sleep quality (i.e. sleep latency and wake after sleep onset). This study highlights that in older adults 'at risk' of dementia, napping is associated with underlying neurobiological changes such as depression and cognition. Napping characteristics should be more routinely monitored in older individuals to elucidate their relationship with psychological and cognitive outcomes.

    Full Text Available Aims: The objective is to propose a brief method to evaluate anosognosia in Alzheimer's disease (AD using the Symptoms of Early Dementia-11 Questionnaire (SED-11Q, a short informant-based screening questionnaire for identifying dementia. Methods: The participants were 107 elderly individuals: 13 with a Clinical Dementia Rating (CDR of 0.5, 73 with mild AD of CDR 1, and 21 with moderate AD of CDR 2. The patients and caregivers answered the SED-11Q independently, and the degree of discrepancy indicated the severity of anosognosia. Results: The scores were as follows: caregiver scores were 2.46 ± 1.85 (mean ± SD in CDR 0.5, 6.36 ± 3.02 in CDR 1, and 9.00 ± 1.14 in CDR 2; patient scores were 2.00 ± 1.78, 2.55 ± 2.33, and 1.33 ± 2.46, respectively. Discrepancy was 0.46 ± 1.61, 3.81 ± 3.95, and 7.67 ± 2.87, respectively, and the caregiver assessments were significantly higher than the patient assessments in CDR 1 and CDR 2 (p Conclusion: The SED-11Q serves a dual purpose: caregiver assessment is useful for the screening of dementia, and any discrepancy between the patient and the caregiver assessment is considered as an indication of the severity of anosognosia; this can be informative for caregivers and essential for successful care.

    Full Text Available Abstract Background The benefit of Ginkgo biloba has been discussed controversially. The aim of this review was to assess the effects of Ginkgo biloba in Alzheimer's disease as well as vascular and mixed dementia covering a variety of outcome domains. Methods We searched MEDLINE, EMBASE, the Cochrane databases, CINAHL and PsycINFO for controlled trials of ginkgo for Alzheimer's, vascular or mixed dementia. Studies had to be of a minimum of 12 weeks duration with at least ten participants per group. Clinical characteristics and outcomes were extracted. Meta-analysis results were expressed as risk ratios or standardized mean differences (SMD in scores. Results Nine trials using the standardized extract EGb761® met our inclusion criteria. Trials were of 12 to 52 weeks duration and included 2372 patients in total. In the meta-analysis, the SMDs in change scores for cognition were in favor of ginkgo compared to placebo (-0.58, 95% confidence interval [CI] -1.14; -0.01, p = 0.04, but did not show a statistically significant difference from placebo for activities in daily living (ADLs (SMD = -0.32, 95% CI -0.66; 0.03, p = 0.08. Heterogeneity among studies was high. For the Alzheimer subgroup, the SMDs for ADLs and cognition outcomes were larger than for the whole group of dementias with statistical superiority for ginkgo also for ADL outcomes (SMD = -0.44, 95% CI -0.77; -0.12, p = 0.008. Drop-out rates and side effects did not differ between ginkgo and placebo. No consistent results were available for quality of life and neuropsychiatric symptoms, possibly due to the heterogeneity of the study populations. Conclusions Ginkgo biloba appears more effective than placebo. Effect sizes were moderate, while clinical relevance is, similar to other dementia drugs, difficult to determine.

    Full Text Available OBJECTIVES: To assess the distribution of dementia subtypes in Brazil using a population-based clinicopathological study. METHOD: Brains from deceased individuals aged ≥50 years old were collected after the next of kin signed an informed consent form and provided information through standardized questionnaires. Post-mortem clinical diagnoses were established in consensus meetings, and only cases with moderate or severe dementia or without cognitive impairment were included in the analysis. Immunohistochemical neuropathological examinations were performed following the universally accepted guidelines. A diagnosis of Alzheimer's disease was made when there were at least both a moderate density of neuritic plaques (Consortium to Establish a Register for Alzheimer's disease B or C and Braak stage III for neurofibrillary tangle distribution. For the diagnosis of vascular dementia, at least three zones or strategic areas had to be affected by infarcts, lacunae, or microinfarcts. RESULTS: From 1,291 subjects, 113 cases were classified as having moderate or severe dementia, and 972 cases were free of cognitive impairment. The neuropathological diagnoses of the dementia sub-group were Alzheimer's disease (35.4%, vascular dementia (21.2%, Alzheimer's disease plus vascular dementia (13.3%, and other causes of dementia (30.1%. Small-vessel disease, which alone was not considered sufficient for a vascular dementia diagnosis, was present in 38.9% of all of the dementia cases and in 16.8% of the group without cognitive impairment (odds ratio = 2.91; 95% confidence interval, 1.53-5.51, adjusted for age, sex, and education. CONCLUSIONS: The relatively high frequencies of vascular dementia and small-vessel disease in the dementia sub-group constitute relevant findings for public health initiatives because control of vascular risk factors could decrease the prevalence of dementia in developing countries.

    Full Text Available Abstract The Semantic Verbal Fluency (SVF test entails the generation of words from a given category within a pre-set time of 60 seconds. Objectives: To verify whether socio-demographic and clinical data of individuals with dementia correlate with the performance on the SVF test and to ascertain whether differences among the criteria of number of answers, clusters and data spread over the intervals, predict clinical results. Methods: This was a retrospective study of 49 charts of demented patients classified according to the Clinical Dementia Rating (CDR scale. We correlated education, age and gender, as well as CDR and Mini-Mental State Exam (MMSE scores with the number of answers, clustering and switching distributed over four 15-second intervals on the SVF test. Results: The correlation between number of answers and quartiles was weak (r=0.407, p=0.004; r=0.484, p<0.001 but correlation between the number of clusters and responses was strong (r=0.883, p<0.001. The number of items on the SVF was statistically significant with MMSE score (p=0.01 and there was a tendency for significance on the CDR (p=0.06. The results indicated little activity regarding what we propose to call cluster recalling in the two groups. Discussion: The SVF test, using number of items generated, was found to be more effective than classic screening tests in terms of speed and ease of application in patients with CDR 2 and 3.

    Mansah, Martha; Coulon, Lyn; Brown, Peter

    2008-06-01

    Aim and objective.  This paper explores reflection stemming from a Dementia Care Mapper's own learning and development concerning person-centred care with older residents living in a dementia specific nursing home. Background.  Dementia Care Mapping has been employed in few Australian residential care facilities to promote person-centred care and the well-being of residents. Reflection has also been used selectively in some practices to improve and evaluate the care process. However, contemporary nursing literature has failed to highlight the usefulness of applying reflection following Dementia Care Mapping with older residents. Method.  The mapper's reflections arose from the Dementia Care Mapping observation of five older residents and writing a daily reflective journal. Findings.  From the reflection, a dominant major theme emerged named as the Learning Experience from Mapping Residents with two sub-themes entitled Mapper's Identification of Resident's Unique Needs and Mapper's Empowerment of Clinicians. Dementia Care Mapping recommendations from the mapper's experience highlighted effective approaches to conducting Dementia Care Mapping in residential care facilities. Conclusions.  The valuable process of reflection to Dementia Care Mapping provided the mapper with clinical insights. Further from the mapper's final reflection, a poem entitled Come Back Mind, Come Back to Me was conceived and penned. Relevance to clinical practice.  The mapper's engagement in ongoing reflection incorporated with Dementia Care Mapping has the potential to promote best practice for the care of older people living in aged care facilities.

  14. Cognitive training for dementia

    Konta, Brigitte

    2005-12-01

    Full Text Available The aim of the HTA report is to evaluate the effectiveness of cognitive training methods to treat cognitive disorders of dementia and other diseases with cognitive deficits. For this purpose, a systematic literature search was carried out first based on the DIMDI superbase retrieval. The identified publications were judged and selected by two independent, methodically competent experts. 33 publications were included in the report. Based on the studies for a normal cognitive development in old age a theory that healthy older people have a considerable capacity reserve for an improved performance in abstract abilities of thinking can be assumed. The first symptoms for older people at risk for dementia are a reduced cognitive capacity reserve. Cognitive training methods therefore focus abilities of abstract memory. Apart from types of dementia another two groups of diseases with cognitive deficits were included in the HTA report: cerebral lesions and schizophrenic psychoses. Studies with mild as well as forms of dementia heavy forms including the Alzheimer disease were included. The described training methods were very heterogeneous with regard to their contents, the temporal sequence and the outcome parameter. The studies were methodically partly contestable. Approximately a third of the studies of all publications could show improvements in the cognitive achievements by the training. Three studies concerning cognitive training methods in case of cerebral lesions were included. All three studies demonstrated a significant improvement in the training group in some outcome parameters. Special cognitive training methods were used for the treatment of cognitive deficits at schizophrenic psychoses. The neurocognitive training (NET, the "Cognitive Remediation Therapy" as well as the strategic training with coaching proved to be effective. The studies, however, were hardly comparable and very heterogeneous in detail. Summarising the cognitive training

  17. Joint modeling for cognitive trajectory and risk of dementia in the presence of death.

    Science.gov (United States)

    Yu, Binbing; Ghosh, Pulak

    2010-03-01

    Dementia is characterized by accelerated cognitive decline before and after diagnosis as compared to normal aging. It has been known that cognitive impairment occurs long before the diagnosis of dementia. For individuals who develop dementia, it is important to determine the time when the rate of cognitive decline begins to accelerate and the subsequent gap time to dementia diagnosis. For normal aging individuals, it is also useful to understand the trajectory of cognitive function until their death. A Bayesian change-point model is proposed to fit the trajectory of cognitive function for individuals who develop dementia. In real life, people in older ages are subject to two competing risks, e.g., dementia and dementia-free death. Because the majority of people do not develop dementia, a mixture model is used for survival data with competing risks, which consists of dementia onset time after the change point of cognitive function decline for demented individuals and death time for nondemented individuals. The cognitive trajectories and the survival process are modeled jointly and the parameters are estimated using the Markov chain Monte Carlo method. Using data from the Honolulu Asia Aging Study, we show the trajectories of cognitive function and the effect of education, apolipoprotein E 4 genotype, and hypertension on cognitive decline and the risk of dementia.

    Voltage gated potassium channel antibodies (VGKC Abs) are known to cause three rare neurological syndromes- neuromyotonia, Morvan's syndrome and limbic encephalitis although an increasing array of other associated neurological symptoms are becoming recognised. The authors describe the case of a 60-year-old female who presented to the neurology clinic with an apparent early onset dementing process. She was noted to have both extrapyramidal and frontal release signs on examination and was admitted for further evaluation. Her dementia investigation including a neoplastic screen was negative except for VGKC antibody positivity. Her symptoms dramatically improved with commencement of immunosuppression. A non-paraneoplastic VGKC antibody associated dementia-like syndrome has rarely been described. The authors add to the few existing reports of what represents an important reversible cause of cognitive impairment.

    2015-05-01

    Bilingualism has been reported to delay the age of retrospective report of first symptom in dementia. This study determined if the age of clinically diagnosed Alzheimer's disease and vascular dementia occurred later for bilingual than monolingual, immigrant and U.S. born, Hispanic Americans. It involved a secondary analysis of the subset of 81 bi/monolingual dementia cases identified at yearly follow-up (1998 through 2008) using neuropsychological test results and objective diagnostic criteria from the Sacramento Area Latino Study on Aging that involved a random sampling of community dwelling Hispanic Americans (N = 1789). Age of dementia diagnosis was analyzed in a 2 × 2 (bi/monolingualism × immigrant/U.S. born) ANOVA that space revealed both main effects and the interaction were non-significant. Mean age of dementia diagnosis was descriptively (but not significantly) higher in the monolingual (M = 81.10 years) than the bilingual (M = 79.31) group. Overall, bilingual dementia cases were significantly better educated than monolinguals, but U.S. born bilinguals and monolinguals did not differ significantly in education. Delays in dementia symptomatology pertaining to bilingualism are less likely to be found in studies: (a) that use age of clinical diagnosis vs. retrospective report of first dementia symptom as the dependent variable; and (b) involve clinical cases derived from community samples rather than referrals to specialist memory clinics.

    Music is an important resource for achieving psychological, cognitive, and social goals in the field of dementia. This paper describes the different types of evidence-based music interventions that can be found in literature and proposes a structured intervention model (global music approach to persons with dementia, GMA-D). The literature concerning music and dementia was considered and analyzed. The reported studies included more recent studies and/or studies with relevant scientific characteristics. From this background, a global music approach was proposed using music and sound-music elements according to the needs, clinical characteristics, and therapeutic-rehabilitation goals that emerge in the care of persons with dementia. From the literature analysis the following evidence-based interventions emerged: active music therapy (psychological and rehabilitative approaches), active music therapy with family caregivers and persons with dementia, music-based interventions, caregivers singing, individualized listening to music, and background music. Characteristics of each type of intervention are described and discussed. Standardizing the operational methods and evaluation of the single activities and a joint practice can contribute to achieve the validation of the application model. The proposed model can be considered a low-cost nonpharmacological intervention and a therapeutic-rehabilitation method for the reduction of behavioral disturbances, for stimulation of cognitive functions, and for increasing the overall quality of life of persons with dementia.

    Full Text Available Background/Aims: To examine the association between self-reported sleep problems and incidence of dementia in community-dwelling elderly people. Methods: 1,041 nondemented participants over 65 years old were examined longitudinally. Sleep problems were estimated using the RAND Medical Outcomes Study Sleep Scale examining sleep disturbance, snoring, sleep short of breath or with a headache, sleep adequacy, and sleep somnolence. Cox regression analysis was used to examine the association between sleep problems and risk for incident dementia. Age, gender, education, ethnicity, APOE-ε4, stroke, heart disease, hypertension, diabetes, and depression were included as covariates. Results: Over 3 years of follow-up, 966 (92.8% participants remained nondemented, while 78 (7.2% developed dementia. In unadjusted models, sleep inadequacy (‘Get the amount of sleep you need' at the initial visit was associated with increased risk of incident dementia (HR = 1.20; 95% CI 1.02-1.42; p = 0.027. Adjusting for all the covariates, increased risk of incident dementia was still associated with sleep inadequacy (HR = 1.20; 95% CI 1.01-1.42; p = 0.040, as well as with increased daytime sleepiness (‘Have trouble staying awake during the day' (HR = 1.24; 95% CI 1.00-1.54; p = 0.047. Conclusion: Our results suggest that sleep inadequacy and increased daytime sleepiness are risk factors for dementia in older adults, independent of demographic and clinical factors.

    Full Text Available Aim. Autoimmune rheumatic diseases (ARD are characterized by systemic inflammation and may affect multiple organs and cause vascular events such as ischemic stroke and acute myocardial infarction. However, the association between ARD and increased risk of dementia is uncertain. This is a retrospective cohort study to investigate and compare the risk of dementia between patients clinically diagnosed with ARD and non-ARD patients during a 5-year follow-up period. Methods. Data were obtained from the Longitudinal Health Insurance Database 2000 (LHID2000. We included 1221 patients receiving ambulatory or hospitalization care and 6105 non-ARD patients; patients were matched by sex, age, and the year of index use of health care. Each patient was studied for 5 years to identify the subsequent manifestation of dementia. The data obtained were analyzed by Cox proportional hazard regression. Results. During the 5-year follow-up period, 30 ARD (2.48% and 141 non-ARD patients (2.31% developed dementia. During the 5-year follow-up period, there were no significant differences in the risks of any type of dementia (adjusted hazard ratio (HR, 1.18; 95% CI, 0.79–1.76 in the ARD group after adjusting for demographics and comorbidities. Conclusions. Within the 5-year period, patients with and without ARD were found to have similar risks of developing dementia.

    Prevention and treatment of dementia has turned into a major public health challenge. Recent epidemiological studies have shown a significant association between the presence of hypertension and the occurrence of cognitive decline or dementia (including Alzheimer's disease). Indeed, the summation of vascular brain damage and degenerative changes may contribute to an early expression of a still subclinical Alzheimer's disease, causing the threshold of dementia to be reached earlier. Some recent randomized controlled trials (SYST-EUR, PROGRESS, HOPE, SCOPE, HYVET) included cognition as secondary endpoint. Their results open the way for prevention of dementia by antihypertensive treatments. It is therefore necessary that further randomized trials are conducted with the primary objective to assess the impact of antihypertensive treatment on cognitive decline or dementia. In clinical practice, it is important to identify, among hypertensive patients, the subjects at risk for dementia, i.e those who already have mild cognitive impairment or extensive cerebral white matter lesions, in order to optimize blood pressure control and monitor cognitive function (regular cognitive assessment, drugs adherence).

    Full Text Available Abstract Background Crisis is a term frequently used in dementia care lacking a standardized definition. This article systematically reviews existing definitions of crisis in dementia care literature to create a standardized definition that can be utilized for research, policy and clinical practice. Methods We systematically searched for articles containing definitions of crisis in the context of dementia care. We created an operational framework of crisis based on retrieved definitions. Recommendations to address crisis situations were reviewed and classified according to care settings. Results Abstracts and titles of 1,113 articles, screened from PubMed and EMBASE, were narrowed down to 27 articles. After review, crisis in dementia was defined as a process where a stressor causes an imbalance requiring an immediate decision to be made which leads to a desired outcome and therefore a resolution of the crisis. If the crisis is not resolved, the cycle continues. Recommendations for resolving crisis involving persons with dementia and their caregivers include awareness therapy after diagnosis and increased contact with general practitioners, case manager consultations, caregiver support and education. Furthermore, nursing home staff should be attuned to the environmental, physical and psychological needs of persons with dementia. Conclusions This is the first article to review the definition of crisis in the context of dementia care. A review of the literature indicated that the definition of a crisis is idiosyncratic. Therefore, it is difficult to prevent or plan for all crises. We used an operational framework to compile types of crisis stressors and recommendations from the crisis literature based on three different perspectives; the person with the dementia, the caregiver and the healthcare providers.

    The study explored whether apathy and depressive mood symptoms (DMS) are related to cognitive and functional features of dementia in 63 nursing home (NH) residents with early-onset dementia (EOD). All EOD residents from one NH (n = 41) and a random sample from another NH were assessed for depressive symptoms (Montgomery Asberg Depression Rating Scale [MADRS]), apathy (Neuropsychiatric Inventory [NPI]), global cognitive functions (Mini-Mental State Examination [MMSE]), activities of daily living (ADL, Minimum Data Set-Resident Assessment Instrument [MDS-RAI]), and overall dementia severity (Global Deterioration Scale [GDS]). DMS were not associated with apathy and dementia severity. Regression analyses adjusted for age, gender, the type of dementia, and DMS revealed that dementia severity measures accounted, respectively, for 14% (ADL), 13% (GDS), and 9% (MMSE) of the variance in apathy. In line with previous research in older patients, the higher apathy scores were associated with more cognitive and functional problems in EOD.

    Lars Frings

    Full Text Available Behavioural variant frontotemporal dementia (bvFTD and Alzheimer's disease (AD dementia are characterised by progressive brain atrophy. Longitudinal MRI volumetry may help to characterise ongoing structural degeneration and support the differential diagnosis of dementia subtypes. Automated, observer-independent atlas-based MRI volumetry was applied to analyse 102 MRI data sets from 15 bvFTD, 14 AD, and 10 healthy elderly control participants with consecutive scans over at least 12 months. Anatomically defined targets were chosen a priori as brain structures of interest. Groups were compared regarding volumes at clinic presentation and annual change rates. Baseline volumes, especially of grey matter compartments, were significantly reduced in bvFTD and AD patients. Grey matter volumes of the caudate and the gyrus rectus were significantly smaller in bvFTD than AD. The bvFTD group could be separated from AD on the basis of caudate volume with high accuracy (79% cases correct. Annual volume decline was markedly larger in bvFTD and AD than controls, predominantly in white matter of temporal structures. Decline in grey matter volume of the lateral orbitofrontal gyrus separated bvFTD from AD and controls. Automated longitudinal MRI volumetry discriminates bvFTD from AD. In particular, greater reduction of orbitofrontal grey matter and temporal white matter structures after 12 months is indicative of bvFTD.

    Caregiver burden is greater in frontotemporal dementia (FTD) than in Alzheimer disease (AD). However, little is known of the impact of the 3 main clinical variants of FTD- behavioral-variant frontotemporal dementia (bvFTD), semantic dementia (SemDem), and progressive nonfluent aphasia (PNFA)-or the role of disease severity in caregiver burden. The Zarit Burden Inventory was used to measure caregiver burden of bvFTD (n=17), SemDem (n=20), PNFA (n=20), and AD (n=19) patients. Symptom duration, caregiver age, and relationship type were matched across groups. Moreover, a number of caregiver (mood, social network) and patient variables (functional disability, behavioral changes, relationship with caregiver, and dementia stage) were addressed to investigate their impact on caregiver burden. Caregivers of bvFTD patients reported the highest burden, whereas SemDem and PNFA caregivers reported burden similar to AD. A regression analysis revealed that caregiver burden in FTD, regardless of subtype, was explained by a model combining disease staging, relationship changes, and caregiver depression. Burden increased with disease severity in FTD. This study is the first to show that caregivers of SemDem, PNFA, and AD patients show similar burden, while confirming that bvFTD caregivers show higher burden than AD caregivers. More importantly, this study demonstrates that burden worsens with disease progression in FTD.

    Objective Our study aims were to establish whether subjects enrolled in current obstetric clinical trials proportionately reflects the contemporary representation of Hispanic ethnicities and their birth rates in the United States. Methods Using comprehensive source data over a defined interval (January 2011-September 2015) on birth rates by ethnicity from the Centers for Disease Control and Prevention (CDC), we evaluated the proportional rate by ethnicity, then analyzed the observed to expected relative ratio of enrolled subjects. Results Hispanic women comprise a significant contribution to births in the United States (23% of all births). Systematic analysis of 90 published obstetric clinical trials showed a correlation between inclusion of Hispanic gravidae and the corresponding state's birth rates (r = 0.501, p < 0.001). While the mean was strongly correlated, individual clinical trials may have relatively over-enrolled (n = 31, or 34%) or under-enrolled (n = 33, or 37%) relative to their regional population. In 48% of obstetric clinical trials the Hispanic proportion of the study population was not reported. Conclusion Hispanic gravidae represent a significant number of contemporary U.S. births, and are generally adequately represented as obstetric subjects in clinical trials. However, this is trial-dependent, with significant trial-specific under- and over-enrollment of Hispanic subjects relative to the regional birth population.

    Heart rate variability (HRV) has been conventionally analysed with time- and frequency-domain methods, which measure the overall magnitude of RR interval fluctuations around its mean value or the magnitude of fluctuations in some predetermined frequencies. Analysis of heart rate dynamics by novel methods, such as heart rate turbulence after ventricular premature beats, deceleration capacity of heart rate and methods based on chaos theory and nonlinear system theory, have gained recent interest. Recent observational studies have suggested that some indices describing nonlinear heart rate dynamics, such as fractal scaling exponents, heart rate turbulence and deceleration capacity, may provide useful prognostic information in various clinical settings and their reproducibility may be better than that of traditional indices. For example, the short-term fractal scaling exponent measured by the detrended fluctuation analysis method has been shown to predict fatal cardiovascular events in various populations. Similarly, heart rate turbulence and deceleration capacity have performed better than traditional HRV measures in predicting mortality in post-infarction patients. Approximate entropy, a nonlinear index of heart rate dynamics, which describes the complexity of RR interval behaviour, has provided information on the vulnerability to atrial fibrillation. There are many other nonlinear indices which also give information on the characteristics of heart rate dynamics, but their clinical usefulness is not as well established. Although the concepts of nonlinear dynamics, fractal mathematics and complexity measures of heart rate behaviour, heart rate turbulence, deceleration capacity in relation to cardiovascular physiology or various cardiovascular events are still far away from clinical medicine, they are a fruitful area for research to expand our knowledge concerning the behaviour of cardiovascular oscillations in normal healthy conditions as well as in disease states.

    @@ Dementia is becoming a major concern worldwide because its prevalence and incidence rise exponentially with increasing age. The prevalence rates double with every 5 years of age, from about 5% (4-12%depending on the studies) in those aged 65 and older to about 40% over 90[1], and up to 58% in those 95 and older[2]. The annual incidence rate of dementia is 2.2% per year over age 65[3]. According to 1996 United Nations projections, the number of individuals ~ed 65 and older in the more developed countries will increase from 169 million (14.2% of the population) to 287 million (24. 7% of the population)[3]. Besides the huge human and social costs, the economic burden of dementia is enormous in countries with a long lifeexpectancy[3], both from direct costs, i.e., those that result in actual monetary expenditures, such as hospital care, physician visits, medications, home health care workers or institutional care and indirect costs, i.e.,those that do not result in actual monetary expenditures, such as time spouses or other caregivers spend helping and caring.

    Endocrine diseases affecting various organs, such as the pituitary gland, the thyroid, the parathyroid, the adrenal glands and the pancreas, occasionally cause dementia. While Alzheimer's disease (AD) is the main cause of dementia in the elderly and is untreatable, dementia caused by endocrine diseases is treatable in most cases. However, patients with dementia associated with endocrine diseases show memory impairments similar to those found in AD, often leading to misdiagnoses. Patients with endocrine diseases often present with other characteristic systemic and neuropsychiatric symptoms caused by altered hormone levels. Such neuropsychiatric symptoms include involuntary movements, depression, seizures, and muscle weakness. In these cases, abnormalities in imaging and blood or urine tests are helpful in making a differential diagnosis. As delays in the diagnosis and treatment of these patients may cause irreversible brain damage, it is imperative for clinicians to carefully exclude the possibility of latent endocrine diseases when treating patients with dementia.

    Full Text Available Background/Aims: Prior studies have consistently found a higher risk of dementia in individuals with schizophrenia, but whether this is due to a common etiology between the disorders remains obscure. We wanted to elucidate this association by investigating whether schizophrenia in offspring increases the risk of Alzheimer's dementia. Methods: All individuals born between 1930 and 1953 were identified through national registers and followed from their 50th birthday until the date of Alzheimer's dementia, death or end of the study. Regressions were performed to evaluate the association between offspring with schizophrenia and Alzheimer's dementia. Results: Individuals with offspring with schizophrenia did not have an increased risk of Alzheimer's dementia [incidence rate ratio (IRR, 0.97; 95% CI, 0.88-1.07] compared to individuals with offspring without psychiatric contact. This finding remained stable when evaluating early-onset (IRR, 1.10; 95% CI, 0.91-1.31 and late-onset Alzheimer's dementia (IRR, 0.92; 95% CI, 0.88-1.07. Similar findings were made for vascular and unspecified dementia. Conclusion: The finding of no familial coaggregation between schizophrenia and Alzheimer's dementia may suggest that no common etiology between the disorders exists. This may indicate that the excess risk of dementia in individuals with schizophrenia is a by-product of the higher rates of somatic comorbidity and adverse health risk factors among these individuals.

    Photoacoustic tomography, a hybrid imaging modality combining optical and ultrasound imaging, is gaining attention in the field of medical imaging. Typically, a Q-switched Nd:YAG laser is used to excite the tissue and generate photoacoustic signals. But, such photoacoustic imaging systems are difficult to translate into clinical applications owing to their high cost, bulky size often requiring an optical table to house such lasers. Moreover, the low pulse repetition rate of few tens of hertz prevents them from being used in high frame rate photoacoustic imaging. In this work, we have demonstrated up to 7000 Hz photoacoustic imaging (B-mode) and measured the flow rate of a fast moving object. We used a ~140 nanosecond pulsed laser diode as an excitation source and a clinical ultrasound imaging system to capture and display the photoacoustic images. The excitation laser is ~803 nm in wavelength with ~1.4 mJ energy per pulse. So far, the reported 2-dimensional photoacoustic B-scan imaging is only a few tens of frames per second using a clinical ultrasound system. Therefore, this is the first report on 2-dimensional photoacoustic B-scan imaging with 7000 frames per second. We have demonstrated phantom imaging to view and measure the flow rate of ink solution inside a tube. This fast photoacoustic imaging can be useful for various clinical applications including cardiac related problems, where the blood flow rate is quite high, or other dynamic studies.

    2016-01-01

    Interest in palliative care for people with dementia has been around for over two decades. There are clinical and ethical challenges and practical problems around the implementation of good quality palliative care in dementia. This narrative review of the literature focuses on the rationale or basis for services, some of the ethical issues that arise (particularly to do with artificial nutrition and hydration) and on the provision and implementation of services. We focus on the most recent literature. The rationale for palliative care for people with dementia is based on research and on an identified need for better clinical care. But the research largely demonstrates a paucity of good quality evidence, albeit particular interventions (and non-interventions) can be justified in certain circumstances. Numerous specific clinical challenges in end-of-life care for people with dementia are ethical in nature. We focus on literature around artificial nutrition and hydration and conclude that good communication, attention to the evidence and keeping the well-being of the person with dementia firmly in mind will guide ethical decision-making. Numerous challenges surround the provision of palliative care for people with dementia. Palliative care in dementia has been given definition, but can still be contested. Different professionals provide services in different locations. More research and education are required. No single service can provide palliative care for people with dementia.

The Family Caregiving Inventory was used to assess family caregivers for caregiving activities, role strain, role preparation, and help from others at different stages of care receivers’ dementia.Results: Family caregivers’ caregiving activities were related to patients’ stages of dementia. For patients with mild dementia, caregivers provided more assistance in transportation and housekeeping. In addition to these two activities, family caregivers of patients with moderate dementia provided more assistance with mobility and protection. For patients with severe dementia, family caregivers provided more assistance with personal care, mobility and protection, transportation, and housekeeping. Overall, family caregivers reported having some preparation to provide care; the most difficult caregiving activity was identified as managing behavioral problems.Conclusion: This study’s results provide a knowledge base

    Full Text Available Howard S KirshnerDepartment of Neurology, Vanderbilt University Medical Center, Nashville, TN, USAAbstract: Frontotemporal dementias are neurodegenerative diseases in which symptoms of frontal and/or temporal lobe disease are the first signs of the illness, and as the diseases progress, they resemble a focal left hemisphere process such as stroke or traumatic brain injury, even more than a neurodegenerative disease. Over time, some patients develop a more generalized dementia. Four clinical subtypes characterize the predominant presentations of this illness: behavioral or frontal variant FTD, progressive nonfluent aphasia, semantic dementia, and logopenic primary progressive aphasia. These clinical variants correlate with regional patterns of atrophy on brain imaging studies such as MRI and PET scanning, as well as with biochemical and molecular genetic variants of the disorder. The treatment is as yet only symptomatic, but advances in molecular genetics promise new therapies.Keywords: FTD, behavior variant or frontal variant FTD, pick's disease, PPA, progressive nonfluent aphasia

    Full Text Available Abstract Background The independent effects of stress on the health of primary care patients might be different for different types of clinic populations. This study examines these relationships in a low-income female population of patients attending a family planning clinic. Methods This study investigated the relevance of different sources of personal stress and social support to self-rated health, adjusting for mental health, health behavior and demographic characteristics of subjects. Five hundred women who attended family planning clinics were surveyed and 345 completed the form for a response rate of 72 percent. Results Multiple logistic regression analysis revealed that liking oneself was related to good self-rated health (Odds ratio = 7.11, but stress or support from children, parents, friends, churches or spouses were not significant. White non-Hispanic and non-white non-Hispanic respondents had lower odds of reporting good self-rated health than Hispanic respondents (odds ratios were 2.87 and 2.81, respectively. Exercising five or more days per week also was related to good self-rated health. Smoking 20 or more cigarettes per day, and obese III were negatively related to good self-rated health (odds ratios were .19 and .22, respectively with corresponding p-values equal to .0043 and .0332. Conclusions Among younger low-income women, addressing low self-esteem might improve health status.

    Full Text Available Aim: This study aims to provide a brief questionnaire form of the Neuropsychiatric Inventory (NPI-Q in Korean translated from the original NPI-Q that is intended for the evaluation of behavioral and psychological symptoms of dementia in routine clinical practice. Patients and Methods: We developed a Korean version of the NPI-Q (KNPI-Q and compared subitems with those of the Korean version of the NPI (KNPI in 63 dementia patients; 47 patients had been diagnosed with Alzheimer's disease with dementia, 8 with vascular dementia, and 8 with dementia with Lewy body disease. The diagnosis was based on the National Institute of Neurological and Communicative Disorders and Stroke - Alzheimer's Disease and Related Disorders Association criteria for possible and probable Alzheimer's disease and the International Statistical Classification of Diseases and Related Health Problems, 10th revision, criteria for vascular dementia and other dementing diseases. All patients received the Korean version of the Mini-Mental State Examination and the Clinical Dementia Rating within 1 month of the KNPI-Q. Results: Test-retest reliability of the KNPI-Q using a Pearson correlation index was r = 0.89 for the total symptom scale and r = 0.90 for the distress scale. The prevalence of analogous symptom ratings differed by less than 6.7%. Convergent validity between the KNPI-Q and the NPI using a Pearson correlation index was r = 0.879 for the total symptom scale and r = 0.92 for the distress scale. Conclusions: The KNPI-Q is a reliable and brief instrument that can be employed for screening in the evaluation of neuropsychiatric symptoms of dementia and associated caregiver distress. It may be suitable for use in general clinical practice and could be administered as a brief neuropsychiatric interview.

    Three cases of manic-depressive illness are presented which, with various manifestations of pseudodementia, end in dementia. The relationship of cyclothymia to dementia is discussed, and the need for diagnosis with the aid of equipment is stressed. Notwithstanding the absence of systematic theories, it seems most probable that senile dementia (Alzheimer dementia) may be associated with cyclothymia.

    This study was intended to, meta-analytically, review whether the subtests of the Wechsler Adult Intelligence Scale are useful in differentiating between vascular dementia and Alzheimer's disease. We expected the Alzheimer's disease group to outperform the vascular dementia group on those subtests that require executive functions, whereas inferior performance of the Alzheimer's disease patients was expected on memory tests. Two steps in the analysis were undertaken in an attempt to clarify this issue. The first step consisted of including all studies examining Wechsler Adult Intelligence Scale subtest performance in vascular dementia and Alzheimer's disease patients. Secondly, a subcortical vascular dementia subgroup was distinguished and performance of this subgroup was compared to that of the Alzheimer's disease group.Overall, the analyses showed that both the vascular dementia and, more strongly, the subcortical vascular dementia group revealed decreased executive functions on several subtests compared to the Alzheimer's disease group. The Alzheimer's disease group showed inferior performance on a single semantic memory test only compared to both the vascular dementia and the subcortical vascular dementia groups. These results indicate that several subtests of the Wechsler Adult Intelligence Scale can differentiate between these two clinical groups, and that most of these tests reveal more impaired performance in the vascular dementia group.

    Full Text Available Behavioral disturbances and psychosis associated with dementia are becoming an increasingly common cause of morbidity in patients with dementia. Approximately 70% of individuals with dementia will experience agitation, and 75% will experience symptoms of psychosis such as delusions or hallucinations. The goal of this article is to review the pharmacologic treatment options for behavioral disturbances and psychosis associated with dementia. A literature review was conducted on PubMed/Medline using key words of “dementia” and “interventions.” The results were filtered for meta-analysis, clinical trials, and systematic reviews. The results were then reviewed. At this time, the most evidence exists for the use of a second generation antipsychotics (SGAs, but consideration should be given to their collective boxed warning of morbidity/mortality. The evidence for second line treatments are limited. There is limited evidence to support the use of first generation antipsychotics (FGAs, antidepressants, anticonvulsants, cognitive enhancers, and analgesics. Additional randomized control trials are needed to guide clinical decision making regarding the behavioral disturbances and psychosis associated with dementia.

    Progressive cognitive decline in combination with a cerebrospinal fluid biomarker pattern of low levels of amyloid-β1-42 and high levels of total tau and phosphorylated tau is typical of Alzheimer's disease. However, several neurodegenerative disorders may overlap with Alzheimer's disease both in regards to clinical symptoms and neuropathology. In a uniquely large cohort of dementia patients, we examined the associations of cerebrospinal fluid biomarkers for Alzheimer's disease molecular pathology with clinical dementia diagnoses and disease severity. We cross-referenced the Swedish Dementia Registry with the clinical laboratory database at the Sahlgrenska University Hospital. The final data set consisted of 5676 unique subjects with a clinical dementia diagnosis and a complete set of measurements for cerebrospinal fluid amyloid-β1-42, total tau and phosphorylated tau. In cluster analysis, disregarding clinical diagnosis, the optimal natural separation of this data set was into two clusters, with the majority of patients with early onset Alzheimer's disease (75%) and late onset Alzheimer's disease (73%) assigned to one cluster and the patients with vascular dementia (91%), frontotemporal dementia (94%), Parkinson's disease dementia (94%) and dementia with Lewy bodies (87%) to the other cluster. Frontotemporal dementia had the highest cerebrospinal fluid levels of amyloid-β1-42 and the lowest levels of total tau and phosphorylated tau. The highest levels of total tau and phosphorylated tau and the lowest levels of amyloid-β1-42 and amyloid-β1-42:phosphorylated tau ratios were found in Alzheimer's disease. Low amyloid-β1-42, high total tau and high phosphorylated tau correlated with low Mini-Mental State Examination scores in Alzheimer's disease. In Parkinson's disease dementia and vascular dementia low cerebrospinal fluid amyloid-β1-42 was associated with low Mini-Mental State Examination score. In the vascular dementia, frontotemporal dementia, dementia with

    Case rate payments combined with utilization monitoring may have the potential to improve the quality of care by reducing over and under-treatment. Thus, a national managed care organization introduced case rate payments at one multi-site radiation oncology provider while maintaining only fee-for-service payments at others. This study examined whether the introduction of the payment method had an effect on radiation fractions administered when compared to clinical guidelines. The number of fractions of radiation therapy delivered to patients with bone metastases, breast, lung, prostate, and skin cancer was assessed for concordance with clinical guidelines. The proportion of guideline-based care ascertained from the payer's claims database was compared before (2011) and after (2013) the payment method introduction using relative risks (RR). After the introduction of case rates, there were no significant changes in guideline-based care in breast, lung, and skin cancer; however, patients with bone metastases and prostate cancer were significantly more likely to have received guideline-based care (RR = 2.0 and 1.1, respectively, pcase rate payments, while the over-treatment rate remained steady at 9%, with no significant change (p = 0.20). These findings suggest that the introduction of case rate payments did not adversely affect the rate of guideline-based care at the provider examined. Additional research is needed to isolate the effect of the payment model and assess implications in other populations.

    Pulsed dose rate (PDR) brachytherapy is a treatment modality that combines physical advantages of high dose rate (HDR) brachytherapy with the radiobiological advantages of low dose rate brachytherapy. The aim of this review was to describe the effective clinical use of PDR brachytherapy worldwide in different tumour locations. We found 66 articles reporting on clinical PDR brachytherapy including the treatment procedure and outcome. Moreover, PDR brachytherapy has been applied in almost all tumour sites for which brachytherapy is indicated and with good local control and low toxicity. The main advantage of PDR is, because of the small pulse sizes used, the ability to spare normal tissue. In certain cases, HDR resembles PDR brachytherapy by the use of multifractionated low-fraction dose.

    We developed and evaluated the effect of Multimodal Cognitive Enhancement Therapy (MCET) consisting of cognitive training, cognitive stimulations, reality orientation, physical therapy, reminiscence therapy, and music therapy in combination in older people with mild cognitive impairment (MCI) or mild dementia. This study was a multi-center, double-blind, randomized, placebo-controlled, two-period cross-over study (two 8-week treatment phases separated by a 4-week wash-out period). Sixty-four participants with MCI or dementia whose Clinical Dementia Rating was 0.5 or 1 were randomized to the MCET group or the mock-therapy (placebo) group. Outcomes were measured at baseline, week 9, and week 21. Fifty-five patients completed the study. Mini-Mental State Examination (effect size = 0.47, p = 0.013) and Alzheimer's Disease Assessment Scale-Cognitive Subscale (effect size = 0.35, p = 0.045) scores were significantly improved in the MCET compared with mock-therapy group. Revised Memory and Behavior Problems Checklist frequency (effect size = 0.38, p = 0.046) and self-rated Quality of Life - Alzheimer's Disease (effect size = 0.39, p = 0.047) scores were significantly improved in the MCET compared with mock-therapy. MCET improved cognition, behavior, and quality of life in people with MCI or mild dementia more effectively than conventional cognitive enhancing activities did.

    Full Text Available Frontotemporal dementia (FTD syndromes comprise a heterogeneous group of neurodegenerative conditions characterized by atrophy in the frontal and temporal lobes. Three main clinical variants are recognized: Behavioral variant (bv-FTD, Semantic dementia (SD, and Progressive nonfluent aphasia (PNFA. However, logopenic/phonological (LPA variant has been recently described, showing a distinctive pattern of brain atrophy and often associated to Alzheimer′s disease pathology. The diagnosis of FTD is challenging, since there is clinical, pathological, and genetic overlap between the variants and other neurodegenerative diseases, such as motoneuron disease (MND and corticobasal degeneration (CBD. In addition, patients with gene mutations (tau and progranulin display an inconsistent clinical phenotype and the correspondence between the clinical variant and its pathology is unpredictable. New cognitive tests based on social cognition and emotional recognition together with advances in molecular pathology and genetics have contributed to an improved understanding. There is now a real possibility of accurate biomarkers for early diagnosis. The present review concentrates on new insights and debates in FTD.

  7. Dementia and the Power of Music Therapy.

    2015-10-01

    Dementia is now a leading cause of both mortality and morbidity, particularly in western nations, and current projections for rates of dementia suggest this will worsen. More than ever, cost effective and creative non-pharmacological therapies are needed to ensure we have an adequate system of care and supervision. Music therapy is one such measure, yet to date statements of what music therapy is supposed to bring about in ethical terms have been limited to fairly vague and under-developed claims about an improvement in well-being. This article identifies the relevant sense of wellbeing at stake in the question of dementia therapies of this type. In broad terms the idea is that this kind of therapy has a restorative effect on social agency. To the extent that music arouses a person through its rhythms and memory-inducing effects, particularly in communal settings, it may give rise to the recovery of one's narrative agency, and in turn allow for both carer and patient to participate in a more meaningful and mutually engaging social connection.

METHODOLOGY AND PRINCIPAL FINDINGS: This was a randomised controlled trial in which the person with dementia-caregiver dyad was randomly allocated either to receive the intervention immediately or to a waiting list group which received the intervention after 6 months. It was carried out in communities based in two talukas (administrative blocks in Goa, India. Mild to moderate cases with dementia (diagnosed using the DSM IV criteria and graded using the Clinical Dementia Rating scale and their caregivers were included in the trial. Community based intervention provided by a team consisting of Home Care Advisors who were supervised by a counselor and a psychiatrist, focusing on supporting the caregiver through information on dementia, guidance on behaviour management, a single psychiatric assessment and psychotropic medication if needed. We measured caregiver mental health (General Health Questionnaire, caregiver burden (Zarit Burden Score, distress due to behavioural disturbances (NPI-D, behavioural problems in the subject (NPI-S and activities of daily living in the elder with dementia (EASI. Outcome evaluations were masked to the allocation status. We analysed each outcome with a mixed effects model. 81 families enrolled in the trial; 41 were randomly allocated to the intervention. 59 completed the trial and 18 died during the trial. The intervention led to a significant reduction of GHQ (-1.12, 95% CI -2.07 to -0.17 and NPI-D scores (-1.96, 95%CI -3.51 to -0.41 and non-significant reductions in the ZBS, EASI and NPI-S scores.

    We aimed to examine whether total intracranial volume (TICV), a marker of premorbid brain size, modified the impact of the apolipoprotein E (apoE) e4 phenotype and ischemic white matter lesions (WMLs) on odds for dementia. The study comprised a population-based sample of 104 demented and 135 nondemented 85-year-olds, and included physical and neuropsychiatric examinations, and head computerized tomography (CT). Dementia disorders were defined according to standard criteria. TICV and WMLs were rated on computerized tomography. Using the highest group as reference, the risk for dementia, Alzheimer's disease (AD), and vascular dementia (VaD) was increased in those with the smallest half, tertile, and quartile of TICV. Smaller TICV increased the odds of dementia, Alzheimer's disease, and vascular dementia in participants with WMLs. WMLs were not associated with increased odds of dementia in those with the largest TICV. The interaction term WMLs*TICV was also significant. TICV did not modify the odds of dementia in those with the apolipoprotein e4 phenotype. Our results suggest that the impact of brain pathology on the risk of dementia is modified by premorbid brain size.

    Professional and advocacy organizations have long urged that dementia should be recognized and properly diagnosed. With the passage of the National Alzheimer's Project Act in 2011, an Advisory Council for Alzheimer's Research, Care, and Services was convened to advise the Department of Health and Human Services. In May 2012, the Council produced the first National Plan to address Alzheimer's disease, and prominent in its recommendations is a call for quality measures suitable for evaluating and tracking dementia care in clinical settings. Although other efforts have been made to set dementia care quality standards, such as those pioneered by RAND in its series Assessing Care of Vulnerable Elders (ACOVE), practitioners, healthcare systems, and insurers have not widely embraced implementation. This executive summary (full manuscript available at www.neurology.org) reports on a new measurement set for dementia management developed by an interdisciplinary Dementia Measures Work Group (DWG) representing the major national organizations and advocacy organizations concerned with the care of individuals with dementia. The American Academy of Neurology (AAN), the American Geriatrics Society, the American Medical Directors Association, the American Psychiatric Association, and the American Medical Association-convened Physician Consortium for Performance Improvement led this effort. The ACOVE measures and the measurement set described here apply to individuals whose dementia has already been identified and properly diagnosed. Although similar in concept to ACOVE, the DWG measurement set differs in several important ways; it includes all stages of dementia in a single measure set, calls for the use of functional staging in planning care, prompts the use of validated instruments in patient and caregiver assessment and intervention, highlights the relevance of using palliative care concepts to guide care before the advanced stages of illness, and provides evidence-based support

    In addition to increased risks of macrovascular and microvascular complications, patients with type 2 diabetes mellitus (T2DM) usually also are at increased risk for cognitive impairment and dementia. Hypoglycemia, a common consequence of diabetes treatment, is considered an independent risk factor for dementia in patients with T2DM. Hypoglycemia and dementia are clinically underestimated and are related to poor outcomes; thus, they may compromise the life expectancy of patients with T2DM. Epidemiological evidence of hypoglycemia-associated cognitive decline and dementia is highly varied. Acute, severe hypoglycemic episodes induce chronic subclinical brain damage, cognitive decline, and subsequent dementia. However, the effects of recurrent moderate hypoglycemia on cognitive decline and dementia remain largely uninvestigated. Poor glycemic control (including fluctuation of hemoglobin A1C [HbA1c] and glucose values) and the viscous circle of bidirectional associations between dementia and hypoglycemia may be clinically relevant. The possible pathophysiological hypotheses include post-hypoglycemic neuronal damage, inflammatory processes, coagulation defects, endothelial abnormalities, and synaptic dysfunction of hippocampal neurons during hypoglycemia episodes. This article reviews previous findings, provides insight into the detection of groups at high risk of hypoglycemia-associated dementia, and proposes specific strategies to minimize the potential burdens associated with hypoglycemia-related neurocognitive disorders in patients with T2DM.

    Heart rate variability is a physiological feature indicating the influence of the autonomic nervous system on the heart rate. Association of the reduced heart rate variability due to myocardial infarction and the increased postinfarction mortality was first described more than thirty years ago. Many studies have unequivocally demonstrated that coronary artery bypass grafting surgery generally leads to significant reduction in heart rate variability, which is even more pronounced than after myocardial infarction. Pathophysiologically, however, the mechanisms of heart rate variability reduction associated with acute myocardial infarction and coronary artery bypass grafting are different. Generally, heart rate variability gradually recovers to the preoperative values within six months of the procedure. Unlike the reduced heart rate variability in patients having sustained myocardial infarction, a finding of reduced heart rate variability after coronary artery bypass surgery is not considered relevant in predicting mortality. Current knowledge about changes in heart rate variability in coronary patients and clinical relevance of such a finding in patients undergoing coronary artery bypass grafting are presented.

    Full Text Available OBJECTIVE: To determine if older men who use computers have lower risk of developing dementia. METHODS: Cohort study of 5506 community-dwelling men aged 69 to 87 years followed for up to 8.5 years. Use of computers measured as daily, weekly, less than weekly and never. Participants also reported their use of email, internet, word processors, games or other computer activities. The primary outcome was the incidence of ICD-10 diagnosis of dementia as recorded by the Western Australian Data Linkage System. RESULTS: 1857/5506 (33.7% men reported using computers and 347 (6.3% received a diagnosis of dementia during an average follow up of 6.0 years (range: 6 months to 8.5 years. The hazard ratio (HR of dementia was lower among computer users than non-users (HR = 0.62, 95%CI = 0.47-0.81, after adjustment for age, educational attainment, size of social network, and presence of depression or of significant clinical morbidity. The HR of dementia appeared to decrease with increasing frequency of computer use: 0.68 (95%CI = 0.41-1.13, 0.61 (95%CI = 0.39-0.94 and 0.59 (95%CI = 0.40-0.87 for less than weekly, at least weekly and daily. The HR of dementia was 0.66 (95%CI = 0.50-0.86 after the analysis was further adjusted for baseline cognitive function, as measured by the Mini-Mental State Examination. CONCLUSION: Older men who use computers have lower risk of receiving a diagnosis of dementia up to 8.5 years later. Randomised trials are required to determine if the observed associations are causal.

    Full Text Available Abstract Background In patients with very severe dementia self-rating of quality of life usually is not possible and appropriate instruments for proxy-ratings are not available. The aim of this project is to develop an instrument of clinical proxy-ratings for this population. Methods Using electronic instruments, physicians and nurses recorded patient behaviour and changes of behaviour over a period of one year. Based on these data a list of 65 items was generated and subsequently allocated to 14 categories. This list was tested in 217 patients (61–105 yrs with dementia diagnosed according to ICD-10 by both physicians and nurses. The severity of dementia was assessed by means of the Global Deterioration Scale (GDS and the Brief Cognitive Rating Scale (BCRS. The Spitzer-Index (proxy-rating was used as a global quality of life measure. Activity of daily living was rated using the Barthel Index. Results A factor analysis of the original 65 items revealed 5 factors (communication, negative affect, bodily contact, aggression, and mobility. By stepwise removing items we obtained satisfactory internal consistencies of the factors both for nurses' and physicians' ratings. The factors were generally unrelated. The validity of the instrument was proven by correlations of the factors communication and mobility with the Brief Cognitive Rating Scale (BCRS and the Barthel-Index. Conclusion The results demonstrate the reliability and validity of the Vienna List as a proxy rating measurement of quality of life in patients with severe dementia. The psychometric properties of the scale have to be proved in further studies.

    Dementia is a public health priority and its importance is projected to increase in coming decades, particularly in low-to middle-income countries. A description of the methodological challenges of observational studies and the limitations of previous attempts to combine the published literature leads me to discuss ascertainment of dementia cases and the suitability of dementia mortality as an outcome. I report the findings of a memory clinic study where 71.5% of 502 deceased individuals with...

    Background and Purpose: It has been suggested that the actual dose rate of an irradiating source may be a distinct influencing factor for the biological effect after brachytherapy with ruthenium-106 for uveal melanoma. The purpose of this study was to investigate a hypothesized impact of the dose rate on the clinical and echographic course after brachytherapy. Patients and Methods: In total, 45 patients were included in this retrospective study. According to the actual dose rate, two groups were defined: group 1 with a dose rate < 4 Gy/h and group 2 with a dose rate {>=} 4 Gy/h. Regarding age, tumor height, basal diameter, scleral and apical dose, differences between the groups were not significant. Clinical parameters, including early and late side effects, and echographic courses were compared. Results: A significantly lower metastatic rate was found in group 2. Using univariate Cox proportional hazards regression, only dose rate predicted metastatic spread significantly (p < 0.05), while in a multivariate analysis, using age at the time of treatment, greatest tumor height and greatest basal diameter as covariates, the variable dose rate was of borderline significance (p = 0.077). Patients in group 2 had more early side effects and more pronounced visual decline, but these differences were of borderline significance with p-values of 0.072 and 0.064, respectively. Conclusion: These data suggest that a higher dose rate may confer a lower risk for metastatic spread, but may be associated with more side effects and more pronounced visual decline. (orig.)

  18. Parsing the recognition memory components of the WMS-III face memory subtest: normative data and clinical findings in dementia groups.

    The WMS-III face memory subtest was developed as a quick, reliable, measure of non-verbal recognition memory. While the face memory subtest has demonstrated clinical sensitivity, the test has been criticized for low correlation with other WMS-III visual memory subtests and for failing to differentiate performance between clinical groups. One possible reason for these findings may be due to the impact of response bias associated with recognition memory tests. Four studies were conducted to evaluate the utility of applying signal detection measures to the face memory subtests. The first two studies used the WMS-III standardization data set to determine age and education effects and to present normative and reliability data for hits, false positives, discriminability and response bias. The third study tested the hypothesis that using response components and signal detection measures would enhance the correlation between face memory and the other WMS-III visual memory subtests. The fourth study compared performance of patients with Alzheimer's disease, Huntington's disease, Korsakoff's syndrome and demographically matched controls on the new face memory scores. The new measures did not have higher correlation with other WMS-III visual memory measures than the standard scoring of the test. Analysis of the clinical samples indicated that the discriminability index best differentiated patients from controls. The response components, particularly delayed false positives, differentiated performance among the clinical groups. Normative and reliability data are presented.

    Full Text Available ABSTRACT Objective: To describe characteristics of hippocampal sclerosis dementia. Methods: Convenience sample of Hippocampal sclerosis dementia (HSD recruited from the Johns Hopkins University Brain Resource Center. Twenty-four cases with post-mortem pathological diagnosis of hippocampal sclerosis dementia were reviewed for clinical characterization. Results: The cases showed atrophy and neuronal loss localized to the hippocampus, amygdala and entorrhinal cortex. The majority (79.2% had amnesia at illness onset, and many (54.2% showed abnormal conduct and psychiatric disorder. Nearly 42% presented with an amnesic state, and 37.5% presented with amnesia plus abnormal conduct and psychiatric disorder. All eventually developed a behavioral or psychiatric disorder. Disorientation, executive dysfunction, aphasia, agnosia and apraxia were uncommon at onset. Alzheimer disease (AD was the initial clinical diagnosis in 89% and the final clinical diagnosis in 75%. Diagnosis of frontotemporal dementia (FTD was uncommon (seen in 8%. Conclusion: HSD shows pathological characteristics of FTD and clinical features that mimic AD and overlap with FTD. The findings, placed in the context of earlier work, support the proposition that HSD belongs to the FTD family, where it may be identified as an amnesic variant.

    Purpose: The purpose of this work is to determine the statistical correlation between per-beam, planar IMRT QA passing rates and several clinically relevant, anatomy-based dose errors for per-patient IMRT QA. The intent is to assess the predictive power of a common conventional IMRT QA performance metric, the Gamma passing rate per beam. Methods: Ninety-six unique data sets were created by inducing four types of dose errors in 24 clinical head and neck IMRT plans, each planned with 6 MV Varian 120-leaf MLC linear accelerators using a commercial treatment planning system and step-and-shoot delivery. The error-free beams/plans were used as ''simulated measurements'' (for generating the IMRT QA dose planes and the anatomy dose metrics) to compare to the corresponding data calculated by the error-induced plans. The degree of the induced errors was tuned to mimic IMRT QA passing rates that are commonly achieved using conventional methods. Results: Analysis of clinical metrics (parotid mean doses, spinal cord max and D1cc, CTV D95, and larynx mean) vs IMRT QA Gamma analysis (3%/3 mm, 2/2, 1/1) showed that in all cases, there were only weak to moderate correlations (range of Pearson's r-values: -0.295 to 0.653). Moreover, the moderate correlations actually had positive Pearson's r-values (i.e., clinically relevant metric differences increased with increasing IMRT QA passing rate), indicating that some of the largest anatomy-based dose differences occurred in the cases of high IMRT QA passing rates, which may be called ''false negatives.'' The results also show numerous instances of false positives or cases where low IMRT QA passing rates do not imply large errors in anatomy dose metrics. In none of the cases was there correlation consistent with high predictive power of planar IMRT passing rates, i.e., in none of the cases did high IMRT QA Gamma passing rates predict low errors in anatomy dose metrics or vice versa

    Full Text Available Humanoids have increasingly become the focus of attention in robotics research in recent years, especially in service and personal assistance robotics. This paper presents the application developed for humanoid robots in the therapy of dementia patients as a cognitive stimulation tool. The behaviour of the robot during the therapy sessions is visually programmed in a session script that allows music to play, physical movements (dancing, exercises, etc., speech synthesis and interaction with the human monitor. The application includes the control software on board the robot and some tools like the visual script generator or a monitor to supervise the robot behaviour during the sessions. The robot applicationʹs impact on the patientʹs health has been studied. Experiments with real patients have been performed in collaboration with a centre of research in neurodegenerative diseases. Initial results show a slight or mild improvement in neuropsychiatric symptoms over other traditional therapy methods.

    Few vascular dementias are diagnosed in memory clinic consultations. One type, a rare etiology, Sneddon syndrome, can lead patients to consult for an isolated memory complaint. We report the cases of two patients, aged 63 and 66 years, who presented frontocortical cognitive profile and behavior disorders. Seronegative Sneddon syndrome, complicated with dementia, was diagnosed in each case by noticing an association between, on MRI, an atrophy and several ischemic cerebrovascular accident aftermaths, and a livedo racemosa. Management of vascular risks factors improves the prognosis.

    2013-12-01

    According to a recently published population study conducted in France, exposure to benzodiazepines may be associated with an approximately 50% increase in the risk of dementia in the elderly. However, the clinical interpretation of this finding raised some concerns. A causal link between benzodiazepine use and diagnosis of dementia may be real, but it is nevertheless possible that the increased risk might be due to other confounding factors. In this article, the main strengths and weaknesses of this study are briefly analysed, including the possibility of reverse causation. Implications for research and current practice are discussed.

  10. Self-experience in Dementia

    2015-08-01

    Full Text Available This paper develops a phenomenological analysis of the disturbances of self-experience in dementia. After considering the lack of conceptual clarity regarding the notions of self and person in current research on dementia, we develop a phenomenological theory of the structure of self-experience in the first section. Within this complex structure, we distinguish between the basic level of pre-reflective self-awareness, the episodic sense of self, and the narrative constitution of the self. In the second section, we focus on dementia and argue that, despite the impairment of narrative self-understanding, more basic moments of self-experience are preserved. In accordance with the theory developed in the first part, we argue that, at least until the final stages of the illness, these self-experience in dementia goes beyond the pure minimal self, and rather entail forms of self-reference and an episodic sense of self.

    Bryan A Loy

    Full Text Available Case rate payments combined with utilization monitoring may have the potential to improve the quality of care by reducing over and under-treatment. Thus, a national managed care organization introduced case rate payments at one multi-site radiation oncology provider while maintaining only fee-for-service payments at others. This study examined whether the introduction of the payment method had an effect on radiation fractions administered when compared to clinical guidelines. The number of fractions of radiation therapy delivered to patients with bone metastases, breast, lung, prostate, and skin cancer was assessed for concordance with clinical guidelines. The proportion of guideline-based care ascertained from the payer's claims database was compared before (2011 and after (2013 the payment method introduction using relative risks (RR. After the introduction of case rates, there were no significant changes in guideline-based care in breast, lung, and skin cancer; however, patients with bone metastases and prostate cancer were significantly more likely to have received guideline-based care (RR = 2.0 and 1.1, respectively, p<0.05. For the aggregate of all cancers, the under-treatment rate significantly declined (p = 0.008 from 4% to 0% after the introduction of case rate payments, while the over-treatment rate remained steady at 9%, with no significant change (p = 0.20. These findings suggest that the introduction of case rate payments did not adversely affect the rate of guideline-based care at the provider examined. Additional research is needed to isolate the effect of the payment model and assess implications in other populations.

    Dementia, depression, and Parkinson's disease are in themselves challenging problems in old age. Recognition and diagnosis are often suboptimal. In dementia, many contributing factors must be considered, including nutrition, but in all these conditions the effects of the cognitive, attitudinal, and motor changes can produce permanent and severe nutritional compromise. Yet many simple steps can be taken to prevent poor nutrition in these diseases, and the primary care practitioner is central to this process of recognition and intervention.

    In 2011, about 1.1-1.4 million patients with dementia were living in Germany, a number expected to rise to three million by 2050. Dementia poses a major challenge to the healthcare system and neuropharmacological service provision. The aim of this study was to determine prescription rates for anti-dementia drugs as well as for neuroleptics, sedative-hypnotics and antidepressants in dementia using the complete nationwide outpatient claims data pertaining to the services of statutory health insurance. We controlled for gender, age, dementia diagnosis, physician specialty (general practitioner GP versus neuropsychiatry specialist physician NPSP), and rural and urban living area. In about one million prevalent dementia patients (N=1,014,710) in 2011, the prescription prevalence rate of anti-dementia drugs was 24.6%; it varied with gender, age, and diagnosis (highest in Alzheimer's disease; 42%), and was higher in patients treated by NPSPs (48% vs. 25% in GPs). At the same time, we found an alarmingly high rate of treatment with neuroleptics in dementia patients (35%), with an only slightly decreased risk in patients treated exclusively by NPSPs (OR=0.86). We found marginal differences between rural and urban areas. Our results show that the majority of anti-dementia drug prescriptions appear guideline-oriented, yet prescription rates are overall comparatively low. On the other hand, neuroleptic drugs, which are associated with excess morbidity and mortality in dementia, were prescribed very frequently, suggesting excess use given current guidelines. We therefore suggest that guideline implementation measures and increasing quality control procedures are needed with respect to the pharmacotherapy of this vulnerable population.

    Taiwan has the highest prevalence of chronic kidney disease (CKD) worldwide. CKD, a manifestation of vascular diseases, is associated with a high risk of dementia. Here, we estimated the association between influenza vaccination and dementia risk in patients with CKD. Data from the National Health Insurance Research Database of Taiwan were used in this study. The study cohort included all patients diagnosed with CKD (according to International Classification of Disease, Ninth Revision, Clinical Modification codes) at healthcare facilities in Taiwan (n = 32,844) from January 1, 2000, to December 31, 2007. Each patient was followed up to assess dementia risk or protective factors: demographic characteristics of age and sex; comorbidities of diabetes, hypertension, dyslipidemia, cerebrovascular diseases, parkinsonism, epilepsy, substance and alcohol use disorders, mood disorder, anxiety disorder, psychotic disorder, and sleep disorder; urbanization level; monthly income; and statin, metformin, aspirin, and angiotensin-converting enzyme inhibitor (ACEI) use. A propensity score was derived using a logistic regression model for estimating the effect of vaccination by accounting for covariates that predict receiving the intervention (vaccine). A time-dependent Cox proportional hazard model was used to calculate the hazard ratios (HRs) of dementia among vaccinated and unvaccinated CKD patients. The study population comprised 11,943 eligible patients with CKD; 5745 (48%) received influenza vaccination and the remaining 6198 (52%) did not. The adjusted HRs (aHRs) of dementia decreased in vaccinated patients compared with those in unvaccinated patients (influenza season, noninfluenza season, and all seasons: aHRs = 0.68, 0.58, and 0.64; P dementia in various models. A stronger protective effect against dementia risk was demonstrated during the noninfluenza season. Regardless of comorbidities or drug use, influenza vaccination was an independent protective factor and

    The typical presentation of semantic dementia is associated with marked, left predominant anterior temporal lobe atrophy and with changes in language. About 30% of individuals, however, present with predominant right anterior temporal lobe atrophy, usually accompanied by behavioural changes and prosopagnosia. Here, we aimed to establish whether these initially distinct clinical presentations evolve into a similar syndrome at the neural and behavioural level. Thirty-one patients who presented with predominant anterior temporal lobe atrophy were included. Based on imaging, patients were categorized as either predominant left (n = 22) or right (n = 9) semantic dementia. Thirty-three Alzheimer's disease patients and 25 healthy controls were included for comparison. Participants completed the Addenbrooke's Cognitive Examination, a Face and Emotion Processing Battery and the Cambridge Behavioural Inventory, and underwent magnetic resonance imaging annually. Longitudinal neuroimaging analyses showed greater right temporal pole atrophy in left semantic dementia than Alzheimer's disease, whereas right semantic dementia showed greater orbitofrontal and left temporal lobe atrophy than Alzheimer's disease. Importantly, direct comparisons between semantic dementia groups revealed that over time, left semantic dementia showed progressive thinning in the right temporal pole, whereas right semantic dementia showed thinning in the orbitofrontal cortex and anterior cingulate. Behaviourally, longitudinal analyses revealed that general cognition declined in all patients. In contrast, patients with left and right semantic dementia showed greater emotion recognition decline than Alzheimer's disease. In addition, left semantic dementia showed greater motivation loss than Alzheimer's disease. Correlational analyses revealed that emotion recognition was associated with right temporal pole, right medial orbitofrontal and right fusiform integrity, while changes in motivation were associated

    Using a time-budget method in a 3 year longitudinal study with a control group design, substantial reductions in the engagement of nonobligatory instrumental, social, and leisure activities could be found in a group of mildly to moderately demented patients. Controlling these changes for differences in baseline parameters, the dementia-specific reduction was about 1 1/2 hours compared to a non-psychiatric control group. These clinically relevant changes in activity levels underscore the importance of these activity domains with regard to the development of diagnostically useful indicators at the early stages of dementia. Time-budget methods seem to be particularly useful to close the diagnostic gap with regard to the assessment of everyday competence indicators especially at early stages of the dementia illness.

  20. Reversible dementia as a presenting manifestation of racemose neurocysticercosis

    2013-01-01

    Full Text Available Racemose cysticercosis is a less frequent presentation of neurocysticercosis (NCC. It′s presentation and management is quite different from cerebral parenchymal NCC. Diagnosis of racemose cysticercosis is based on the combination of clinical, epidemiologic, radiographic, and immunologic information. Compared with cysticercus cellulose, which most commonly presents as seizures, racemose NCC due to its extraaxial location presents with raised intracranial pressure and meningitis, and frequently requires neurosurgical intervention. Dementia as a sole presenting feature of NCC is rare. We report a case of racemose NCC with dementia as the presenting manifestation. The outcome of dementia patients with NCC seems favorable in most cases therefore a high index of suspicion for NCC should be kept especially in endemic areas.

    Declines in adaptive behavior were examined in a study of dementia in adults with Down syndrome and other forms of mental retardation. No significant differences were found between adults under 50 years of age with and without Down syndrome. In contrast, individuals over 50 who had Down syndrome were more likely to be classified as having dementia over a range of quantitative decision criteria; nevertheless, prevalence estimates of dementia were substantially below the presumed 100% prevalence of neuropathological markers of Alzheimer disease. This apparent discrepancy between functional and neuropathological findings may be associated with variations in risk associated with Down syndrome genotypes and/or a true lack of correspondence between classical neuropathological hallmarks of Alzheimer disease in this population and clinical expression.

    Objective Rosacea is a common chronic inflammatory skin disorder where upregulation of matrix metalloproteinases (MMPs) and antimicrobial peptides (AMPs) is observed. Notably, inflammation, MMPs, and AMPs are also involved in the etiopathogenesis of neurodegenerative disorders including certain...... forms of dementia such as Alzheimer disease (AD). Based on several clinical observations, we investigated the association between rosacea and dementia, including AD in Danish registers. Methods All Danish citizens aged ≥18 years between January 1, 1997 and December 31, 2012 were linked at the individual...... level through administrative registers. Cox regression was used to calculate unadjusted and adjusted hazard ratios (HRs). Results The study comprised a total of 5,591,718 individuals, including 82,439 patients with rosacea. A total of 99,040 individuals developed dementia (any form) in the study period...

    This is designed to analyze and summarize medication rules for treating senile dementia with Chinese medicine in CNKI according to the traditional Chinese medicine (TCM) inheritance auxiliary system. Collect documents in CNKI that account treating senile dementia with Chinese formula; filter and establish a formula database, and then to search for medication rules on the TCM inheritance auxiliary system. It is filtered that 104 formulas are used for treating senile dementia screening treat senile dementia, involving 147 kinds of Chinese medicine. Tonic medicine are most frequently used, followed by the medicine of activating blood circulation and resuscitating; medicine pair most used is Ligusticum chuanxiong Hort-Acorus tatarinowii, accounting for 27.9% of all formula. And then 8 core pairs and 4 new formulas are evolved. Analysis on formulas for treating senile dementia filtered form CNKI by TCM inheritance auxiliary system shows prescription is mainly tonifying, activating blood circulation and resuscitating, that reveals prescription rules, to provide a reference for clinical treatment.

    Providing information about the latest research via educational sessions to health professionals caring for people with dementia may be insufficient to drive change. This project explored self-reported impacts on practice change of adding information about knowledge translation (KT) to a national dementia education program. Six national workshop days were held. Each provided the option of participating in a Principles of KT and innovation implementation seminar in addition to a clinical topic update (sexualities and dementia, or managing behavioral and psychological symptoms of dementia). Six months postworkshop, 321 participants were invited to complete a research utilization survey. Seventy-five responded. KT seminar participants were more likely to report instrumental outcomes (e.g. changed policies, procedures) than those who did not participate in the KT seminar. Including KT information in educational sessions for health professionals may increase the likelihood of practice change in the field of dementia care and warrants further research.

  6. Dementia: sociological and philosophical constructions.

    Science.gov (United States)

    Davis, Daniel H J

    2004-01-01

    This analysis presents a challenge to the biomedical view of dementia as a disease. This view is critiqued from two perspectives: those of sociology and philosophy. Because these domains inform the creation of the medical discourse, their analysis provides an important refinement to the apprehension of the phenomenon of dementia. From the work of Foucault, and in particular his analysis of the historical origins of modern medicine, the sociological construction of dementia is considered. Following this, the philosophical question of Being is discussed, considering particularly the positions of Heidegger and Merleau-Ponty. Lastly aspects of dementia nursing that are damaging to those relatives forced to take on the role of primary carer are isolated, in the context of Kitwood's view that it is possible to maintain personhood at the extremes of this condition. It is suggested that this critique of sociological and philosophical foundations of dementia might offer a way of approaching the dismantling of the self and revise current conceptions of dementia care for the better.

    An escalating "epidemic" of diseases like Alzheimer's has not yet been met by effective symptomatic treatments or preventative strategies. Among a few current prescription drugs are cholinesterase inhibitors including galantamine, originating from the snowdrop. Research into ethnobotanicals for memory or cognition has burgeoned in recent years. Based on a multi-faceted review of medicinal plants or phytochemicals, including traditional uses, relevant bioactivities, psychological and clinical evidence on efficacy and safety, this overview focuses on those for which there is promising clinical trial evidence in people with dementia, together with at least one other of these lines of supporting evidence. With respect to cognitive function, such plants reviewed include sage, Ginkgo biloba, and complex mixtures of other traditional remedies. Behavioral and psychological symptoms of dementia (BPSD) challenge carers and lead to institutionalization. Symptoms can be alleviated by some plant species (e.g., lemon balm and lavender alleviate agitation in people with dementia; St John's wort treats depression in the normal population). The ultimate goal of disease prevention is considered from the perspective of limited epidemiological and clinical trial evidence to date. The potential value of numerous plant extracts or chemicals (e.g., curcumin) with neuroprotective but as yet no clinical data are reviewed. Given intense clinical need and carer concerns, which lead to exploration of such alternatives as herbal medicines, the following research priorities are indicated: investigating botanical agents which enhance cognition in populations with mild memory impairment or at earliest disease stages, and those for BPSD in people with dementia at more advanced stages; establishing an ongoing authoritative database on herbal medicine for dementia; and further epidemiological and follow up studies of promising phytopharmaceuticals or related nutraceuticals for disease prevention.

    IMPORTANCE In advanced dementia, goals of care decisions are challenging and medical care is often more intensive than desired. OBJECTIVE To test a goals of care (GOC) decision aid intervention to improve quality of communication and palliative care for nursing home residents with advanced dementia. DESIGN, SETTING, AND PARTICIPANTS A single-blind cluster randomized clinical trial, including 302 residents with advanced dementia and their family decision makers in 22 nursing homes. INTERVENTIONS A GOC video decision aid plus a structured discussion with nursing home health care providers; attention control with an informational video and usual care planning. MAIN OUTCOMES AND MEASURES Primary outcomes at 3 months were quality of communication (QOC, questionnaire scored 0–10 with higher ratings indicating better quality), family report of concordance with clinicians on the primary goal of care (endorsing same goal as the “best goal to guide care and medical treatment,” and clinicians’ “top priority for care and medical treatment”), and treatment consistent with preferences (Advance Care Planning Problem score). Secondary outcomes at 9 months were family ratings of symptom management and care, palliative care domains in care plans, Medical Orders for Scope of Treatment (MOST) completion, and hospital transfers. Resident-family dyads were the primary unit of analysis, and all analyses used intention-to-treat assignment. RESULTS Residents’ mean age was 86.5 years, 39 (12.9%) were African American, and 246 (81.5%) were women. With the GOC intervention, family decision makers reported better quality of communication (QOC, 6.0 vs 5.6; P = .05) and better end-of-life communication (QOC end-of-life subscale, 3.7 vs 3.0; P = .02). Goal concordance did not differ at 3 months, but family decision makers with the intervention reported greater concordance by 9 months or death (133 [88.4%] vs 108 [71.2%], P = .001). Family ratings of treatment consistent with

    Evaluation of dementia in patients with early symptoms of cognitive decline is clinically challenging, but the need for early, accurate diagnosis has become more crucial, since several medication for the treatment of mild to moderate Alzheimer' disease are available. Many neurodegenerative diseases produce significant brain function alteration even when structural imaging (CT of MRI) reveal no specific abnormalities. The role of PET and SPECT brain imaging in the initial assessment and differential diagnosis of dementia is beginning to evolve rapidly and growing evidence indicates that appropriate incorporation of PET into the clinical work up can improve diagnostic and prognostic accuracy with respect to Alzheimer's disease, the most common cause of dementia in the geriatric population. In the fast few years, studies comparing neuropathologic examination with PET have established reliable and consistent accuracy for diagnostic evaluations using PET - accuracies substantially exceeding those of comparable studies of diagnostic value of SPECT or of both modalities assessed side by side, or of clinical evaluations done without nuclear imaging. This review deals the role of functional brian imaging techniques in the evaluation of dementias and the role of nuclear neuroimaging in the early detection and diagnosis of Alzheimer's disease.

    Dementia is one of the most important public health problems as a result of the rapid increase in the number of elderly persons worldwide. Improvement of prevention strategies and caring for people with dementia should be undertaken. We performed a door-to-door study to screen all subjects aged 50 years and older (n=4,329 of 33,285 inhabitants) in Al-Quseir city. The screening was performed by 3 neuropsychiatrists, using a modified form of the Mini-Mental State Examination. Suspected cases were subjected to case ascertainment according to Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition, Text Revision, diagnostic criteria for dementia; full clinical assessment; psychometric assessment using Cognitive Abilities Screening Instruments, Hachinski Ischaemic Score, Instrumental Activities of Daily Living Scale and the Geriatric Depression Scale; neuroimaging (computed tomography and/or magnetic resonance imaging); and laboratory investigations for selected patients when indicated. The prevalence of dementia was 2.01% for participants aged 50 years or older and 3.83% for those aged 60 years or older. It increased steeply with increasing age to a maximum of 13.5% for those aged 80 years or older. Alzheimer's dementia (48.3%) was the most common subtype, followed by vascular dementia (36.8%), dementia resulting from general medical conditions (11.5%), and last, dementia resulting from multiple etiologies (3.4%).

    Full Text Available Inderpal Singh,1 Sharan Ramakrishna,1 Kathryn Williamson21Department of Geriatric Medicine, 2Department of Old Age Psychiatry, Ysbyty Ystrad Fawr, Ystrad Mynach, Caerphilly, United KingdomAbstract: The rising prevalence of dementia will have an effect on acute care hospitals around the world. At present, around 40% of patients older than 70 years with acute medical admissions have dementia, but only half of these patients have been diagnosed. Patients with dementia have poorer health outcomes, longer hospital stays, and higher rates of readmissions and institutionalization. Worldwide, health care budgets are severely constrained. National Institute for Health and Care Excellence (NICE has listed ten quality standards for supporting people in living well with dementia. NICE resource implications and commissioning support to implement these guidelines and improve dementia services have been recently published. Although most of the frail elderly patients with dementia are cared for by geriatricians, obstacles to making a diagnosis and to the management of dementia have been recognized. To provide a timely diagnosis of dementia, better care in acute hospital settings, and continuity of care in the community, services integrating all these elements are warranted. Extra resources also will be required for intermediate, palliative care, and mental health liaison services for people with dementia. The Birmingham Rapid Assessment Interface and Discharge service model uses a multiskilled team that provides comprehensive assessment of a person's physical and psychological well-being in a general hospital setting. It has been shown to be an effective model in terms of reducing both length of stay and avoiding readmission. The aim of this review is to discuss the implications of the Rapid Assessment Interface and Discharge model in people with dementia and to critically compare this model with similar published service provisions.Keywords: comorbidity, aged

    Full Text Available Background/Aims: Alzheimer's disease (AD is the most common form of dementia. Neuropsychological assessment of individuals with AD primarily focuses on tests of cortical functioning. However, in clinical practice, the underlying pathologies of dementia are unknown, and a focus on cortical functioning may neglect other domains of cognition, including subcortical and executive functioning. The current study aimed to improve the diagnostic discrimination ability of the Consortium to Establish a Registry for Alzheimer's Disease - Neuropsychological Assessment Battery (CERAD-NAB by adding three tests of executive functioning and mental speed (Trail Making Tests A and B,
