    Studies have found conflicting evidence regarding the association of hypoglycemia with dementia. We evaluated an association of hypoglycemia with subsequent dementia in patients with type 2 diabetes. This retrospective longitudinal cohort study used the Clinical Practice Research Datalink, an electronic medical records data from the United Kingdom, from 2003 to 2012. We included patients aged >65 years diagnosed with type 2 diabetes, with no prior diagnosis of dementia. Dementia was defined using diagnosis codes from medical records. All patients were followed from the date of initial diabetes diagnosis. To account for competing risk of death, we used Fine and Gray's competing risk model to determine the association of hypoglycemia with dementia while adjusting for potential confounders. Hypoglycemia was modeled as a time-dependent covariate. Of 53,055 patients, 5.7% (n = 3,018) had at least one hypoglycemia episodes. The overall incidence rate of dementia was 12.7 per 1,000 person-years. In the fully adjusted model that controlled for all confounders, the occurrence of at least one hypoglycemia episode was associated with 27% higher odds of subsequent dementia (hazard ratio = 1.27; 95% confidence interval = 1.06-1.51). The risk increased with the number of hypoglycemia episodes: one episode (hazard ratio = 1.26; 95% confidence interval = 1.03-1.54); two or more episodes (hazard ratio = 1.50; 95% confidence interval = 1.09-2.08). Hypoglycemia is associated with a higher risk of dementia and may be responsible in part for the higher risk of dementia in patients with diabetes. Alternatively, hypoglycemia may be a marker for undiagnosed cognitive impairment, and we cannot rule out the possibility of reverse causation between hypoglycemia and dementia. © The Author 2016.

    Potentially inappropriate medication (PIM) is associated with an increased risk for detrimental health outcomes in elderly patients. Some antidepressant drugs are considered as PIM, but previous research on the association between antidepressants and subsequent dementia has been inconclusive. Therefore, we investigated whether the intake of antidepressants, particularly of those considered as PIM according to the Priscus list, would predict incident dementia. We used data of a prospective cohort study of non-demented primary care patients (n = 3239, mean age = 79.62) to compute Cox proportional hazards models. The risk for subsequent dementia was estimated over eight follow-ups up to 12 years depending on antidepressant intake and covariates. The intake of antidepressants was associated with an increased risk for subsequent dementia (HR = 1.53, 95% CI: 1.16-2.02, p = .003; age-, sex-, education-adjusted). PIM antidepressants (HR = 1.49, 95% CI: 1.06-2.10, p = .021), but not other antidepressants (HR = 1.04, 95% CI: 0.66-1.66, p = .863), were associated with an increased risk for subsequent dementia (in age-, sex-, education-, and depressive symptoms adjusted models). Significant associations disappeared after global cognition at baseline was controlled for. Methodological limitations such as selection biases and self-reported drug assessments might have influenced the results. Only antidepressants considered as PIM were associated with an increased subsequent dementia risk. Anticholinergic effects might explain this relationship. The association disappeared after the statistical control for global cognition at baseline. Nonetheless, physicians should avoid the prescription of PIM antidepressants in elderly patients whenever possible. Copyright © 2017 Elsevier B.V. All rights reserved.

    Full Text Available Abstract Background In the primary care setting, dementia is often diagnosed relatively late in the disease process. Case finding and proactive collaborative care may have beneficial effects on both patient and informal caregiver by clarifying the cause of cognitive decline and changed behaviour and by enabling support, care planning and access to services. We aim to improve the recognition and diagnosis of individuals with dementia in general practice. In addition to this diagnostic aim, the effects of case finding and subsequent care on the mental health of individuals with dementia and the mental health of their informal carers are explored. Methods and design Design: cluster randomised controlled trial with process evaluation. Participants: 162 individuals ≥ 65 years, in 15 primary care practices, in whom GPs suspect cognitive impairment, but without a dementia diagnosis. Intervention; case finding and collaborative care: 2 trained practice nurses (PNs invite all patients with suspected cognitive impairment for a brief functional and cognitive screening. If the cognitive tests are supportive of cognitive impairment, individuals are referred to their GP for further evaluation. If dementia is diagnosed, a comprehensive geriatric assessment takes place to identify other relevant geriatric problems that need to be addressed. Furthermore, the team of GP and PN provide information and support. Control: GPs provide care and diagnosis as usual. Main study parameters: after 12 months both groups are compared on: 1 incident dementia (and MCI diagnoses and 2 patient and caregiver quality of life (QoL-AD; EQ5D and mental health (MH5; GHQ 12 and caregiver competence to care (SSCQ. The process evaluation concerns facilitating and impeding factors to the implementation of this intervention. These factors are assessed on the care provider level, the care recipient level and on the organisational level. Discussion This study will provide insight

    To discuss the methodological and ethical review challenges encountered by researchers who want to enable people with dementia to be involved in research. There has been increasing recognition of the importance of involving people with dementia in research. However, an argument has centred on the protection of these vulnerable clients versus their freedom to be involved as participants in research. People with dementia do have the right to have their experiences explored. Involving this client group in research is essential to gain a true understanding of their needs. The lead author's experience of conducting a study in which people newly diagnosed with dementia were recruited as research participants. An interpretive phenomenological approach was adopted during this qualitative study, with data collected by means of one to one interviews with people newly diagnosed with dementia. This study was completed within the set timeframe, but a large part of the work was spent gaining ethical approval. This meant that the timeframe of the study period was reduced and as a result, it was only possible to recruit three participants. However, people with dementia are perhaps one of the most vulnerable client groups and it is only right that they should not be subjected to harm. Ethical review is an important part of research. Meeting the ethical requirements of research involving people with dementia requires time and careful preparation to ensure that researchers safeguard the interests of this vulnerable client group, while also allowing the participants the opportunity to exercise their autonomy to their fullest potential. Conducting research that involves people with dementia may be time consuming, but it is only fair that this client group are afforded the freedom to be involved in research. This small time-limited study points to the need for larger pilot studies to hear from individuals what needs they have following a diagnosis of dementia.

  12. Diagnosing dementia: Ethnography, interactional ethics and everyday moral reasoning.

    Hillman, Alexandra

    2017-02-01

    This article highlights the contribution of ethnography and qualitative sociology to the ethical challenges that frame the diagnosis of dementia. To illustrate this contribution, the paper draws on an ethnographic study of UK memory clinics carried out between 2012 and 2014. The ethnographic data, set alongside other studies and sociological theory, contest the promotion of a traditional view of autonomy; the limiting of the point of ethical interest to a distinct moment of diagnosis disclosure; and the failure to recognise risk and uncertainty in the building of clinical 'facts' and their communication. In addressing these specific concerns, this article contributes to the wider debate over the relationship between sociology and bioethics (medical ethics). At the heart of these debates lies more fundamental questions: how can we best understand and shape moral decision-making and ethics that guide behaviour in medical practice, and what should be the guiding ideas, concepts and methods to inform ethics in the clinic? Using the case of dementia diagnosis, this article illustrates the benefits of an ethnographic approach, not just for understanding this ethical problem but also for exploring if and how a more empirically informed ethics can help shape healthcare practices for the better.

    Neuroleptic treatment of psychotic symptoms or agitated behavior in elderly patients diagnosed with dementia is associated with reduced efficacy and increased rates of neuroleptic-induced parkinsonism in comparison to younger patients with schizophrenia. We report the first study to examine the relationship between an in vivo measure of dopaminergic function, plasma homovanillic acid (pHVA), and ratings of psychosis, agitation, and parkinsonism before and after neuroleptic treatment in dementia patients. Pretreatment pHVA was significantly correlated with parkinsonian rigidity, with a trend observed with agitation and hostility. Though mean pHVA did not change during perphenazine treatment, intraindividual change in pHVA at day 15 was correlated with improvement in hostility, with a similar trend for improvement in agitation. These preliminary findings are consistent with reports associating dopaminergic function with agitated, but not psychotic, symptoms in patients diagnosed with dementia, and with a reduced responsivity of dopaminergic systems to neuroleptic treatment in these patients.

  15. Diagnosing, monitoring and managing behavioural variant frontotemporal dementia.

    2017-09-02

    Behavioural variant frontotemporal dementia is characterised by insidious changes in personality and interpersonal conduct that reflect progressive disintegration of the neural circuits involved in social cognition, emotion regulation, motivation and decision making. The underlying pathology is heterogeneous and classified according to the presence of intraneuronal inclusions of tau, TDP-43 or, occasionally, fused in sarcoma proteins. Biomarkers to detect these histopathological changes in life are increasingly important with the development of disease-modifying drugs. A number of gene abnormalities have been identified, the most common being an expansion in the C9orf72 gene, which together account for most familial cases. The 2011 international consensus criteria propose three levels of diagnostic certainty: possible, probable and definite. Detailed history taking from family members to elicit behavioural features underpins the diagnostic process, with support from neuropsychological testing designed to detect impairment in decision making, emotion processing and social cognition. Brain imaging is important for increasing the level of diagnosis certainty over time. Carer education and support remain of paramount importance.

    ABSTRACTBackground:Longitudinal studies of older adults are characterized by high dropout rates, multimorbid conditions, and multiple medication use, especially proximal to death. We studied the association between multiple medication use and incident dementia diagnoses including Alzheimer's disease (AD), vascular dementia (VD), and Lewy-body dementia (LBD), simultaneously accounting for dropout. Using the National Alzheimer's Coordinating Center data with three years of follow-up, a set of covariate-adjusted models that ignore dropout was fit to complete-case data, and to the whole-cohort data. Additionally, covariate-adjusted joint models with shared random effects accounting for dropout were fit to the whole-cohort data. Multiple medication use was defined as polypharmacy (⩾ five medications), hyperpolypharmacy (⩾ ten medications), and total number of medications. Incident diagnoses were 2,032 for AD, 135 for VD, and 139 for LBD. Percentages of dropout at the end of follow-up were as follows: 71.8% for AD, 81.5% for VD, and 77.7% for LBD. The odds ratio (OR) estimate for hyperpolypharmacy among those with LBD versus AD was 2.19 (0.78, 6.15) when estimated using complete-case data and 3.00 (1.66, 5.40) using whole-cohort data. The OR reduced to 1.41 (0.76, 2.64) when estimated from the joint model accounting for dropout. The OR for polypharmacy using complete-case data differed from the estimates using whole-cohort data. The OR for dementia diagnoses on total number of medications was similar, but non-significant when estimated using complete-case data. Reasons for dropout should be investigated and appropriate statistical methods should be applied to reduce bias in longitudinal studies among high-risk dementia cohorts.

    Addenbrooke's Cognitive Examination is a screening test used to diagnose dementia. The third edition of this test (ACE-III) was recently developed. The aim of this study was to translate and validate the ACE-III in Spanish. The ACE-III was translated and adapted to Spanish. It was then administered to a group of healthy subjects as well as a group of patients with different types of mild dementia treated in 2 hospitals in Spain. Internal reliability (Cronbach's alpha = 0.927), inter-rater reliability (intraclass correlation coefficient = 0.976) and test-retest reliability (kappa 0.995) were excellent. Age (r = -0.512) and education (r = 0.659) showed a significant correlation with total test scores. The diagnostic accuracy of ACE-III was higher than that of the Mini-Mental State Examination, particularly for the group with the highest educational level. Researchers obtained normative data and cut-off points for the diagnosis of dementia. The Spanish version of the ACE-III is a reliable and valid test for diagnosing dementia. Its diagnostic accuracy is high, especially in patients with a higher level of education. Copyright © 2014 Sociedad Española de Neurología. Published by Elsevier España, S.L.U. All rights reserved.

    The present study examined the relationship between self-reported physical health, depressive symptoms, and the occurrence of depression diagnosis in Hispanic female dementia caregivers. Participants were 89 Hispanic female dementia caregivers. This study used a cross-sectional design. Baseline depression and physical health data were collected from participants enrolled in the 'Reducing Stress in Hispanic Anglo Dementia Caregivers' study sponsored by the National Institute on Aging. Physical health was assessed using the Medical Outcome Study Short Form-36 (SF-36), a one-item self-report health rating, body mass index, and the presence or history of self-reported physical illness. Depressive symptoms were assessed using the Center for Epidemiologic Studies-Depression Scale (CES-D). The occurrence of depression diagnosis was assessed using the Clinical Interview for DSM-IV Axis I Disorders (SCID). Multiple linear and logistic regression analysis was used to examine the extent to which indices of physical health and depressive symptoms accounted for variance in participants' depressive symptoms and depressive diagnoses. Self-reported indices of health (e.g., SF-36) accounted for a significant portion of variance in both CES-D scores and SCID diagnoses. Caregivers who reported worsened health tended to report increased symptoms of depression on the CES-D and increased likelihood of an SCID diagnosis of a depressive disorder. Self-reported health indices are helpful in identifying Hispanic dementia caregivers at risk for clinical levels of depression.

    In a background of revision of criteria for states of increased risk for progression to dementia, we compare the conversion rate to dementia and Alzheimer's disease (AD) of mild cognitive impairment (MCI) as diagnosed using DSM-5 (DSM-5-MCI) and Petersen's (P-MCI) criteria. A population representative cohort of 4057 dementia-free individuals 55+ years of age was followed up at 2.5 and 4.5 years in Zaragoza, Spain (ZARADEMP). Using the Geriatric Mental State- AGECAT for assessment, research psychiatrists diagnosed DSM-5-MCI and P-MCI following operationalized criteria. 'Conversion rate' (CR), 'annual conversion rate' (ACR), and incidence rate (IR) were calculated along with incidence rate ratio (IRR) to compare the performance of the intermediate cognitive definitions. At 4.5-year follow-up, in individuals aged 65+ years, ACRs for non-cases, P-MCI, and DSM-5-MCI were 0.8, 1.9 and 3.4, respectively, for global dementia. The IRRs were 2.9 and 5.3 for P-MCI and DSM5-MCI, respectively, being the non-cases the reference category. The corresponding values were slightly lower for AD. Conversion rate to dementia and AD was higher using DSM-5-MCI criteria than using Petersen's criteria. However, prediction of the construct still has some way to go, as most MCI individuals did not convert at 4.5-year follow-up. © 2015 John Wiley & Sons A/S. Published by John Wiley & Sons Ltd.

    Dementia is characterised by cognitive deterioration and the manifestation of psychological and behavioural symptoms, especially changes in perception, thought content, mood, and conduct. In addition to drug therapy, non-pharmacological treatments are used to manage these symptoms, and one of these latter treatments is music therapy. Since this novel technique in non-verbal, it can be used to treat patients with dementia at any stage, even when cognitive deterioration is very severe. Patients' responses to music are conserved even in the most advanced stages of the disease DEVELOPMENT: A literature research was carried out using the following databases: Academic Search Complete, PubMed, Science Direct y Dialnet. The period of publication was 2003 to 2013 and the search keywords were 'Music Therapy, Dementia, Behaviour, Behaviour Disorders y Behavioural Disturbances'. Out of the 2188 studies that were identified, 11 studies met inclusion criteria for the systematic review. Music therapy is beneficial and improves behavior disorders, anxiety and agitation in subjects diagnosed with dementia. Copyright © 2014 Sociedad Española de Neurología.

    Nursing home quality measures include the proportion of residents who receive antipsychotics. Residents with bipolar disorder are included even though antipsychotics are FDA-approved for this indication. We evaluated how including residents with bipolar disorder impacted the antipsychotic use quality measure for long-stay residents. We evaluated the agreement of minimum data set (MDS) bipolar disorder diagnoses with Medicare data, whether dementia was diagnosed before bipolar disorder, and how less-specific bipolar disorder diagnoses impacted findings. Cross-sectional study. Nursing homes in Iowa. 21,955 long-stay nursing home residents in the first quarter of 2014. We identified antipsychotic use and bipolar disorder using MDS data. We compared MDS bipolar disorder diagnoses with Chronic Conditions Warehouse (CCW) "ever" bipolar disorder indicators, and prior year claims. We compared CCW condition onset dates to identify bipolar disorder diagnosed after dementia. The mean (SD) proportion receiving antipsychotics was 19.6% (11.1%) with bipolar disorder and 18.3% (10.8%) without. The positive predictive value (PPV) of MDS bipolar disorder diagnoses was 80.2% versus CCW lifetime indicators, and 74.6% versus claims. PPV decreased by 27.1% when "bipolar disorder, unspecified" and "other bipolar disorders" diagnoses were excluded. Nearly three-quarters of residents with bipolar disorder had dementia. Over half of those with dementia had dementia first per CCW records. This proportion was lower among those with more specific bipolar disorder diagnoses or MDS bipolar disorder indicators. Bipolar disorder in nursing home residents is often first diagnosed after dementia using nonspecific diagnoses. This practice deserves further evaluation.

    Both major depression and bipolar disorder are associated with an increased risk of developing dementia. However, the differential risk of dementia between major depression and bipolar disorder is rarely investigated. Using the Taiwan National Health Insurance Research Database, a total of 2291 patients aged ≥ 55 years (major depression: 1946 and bipolar disorder: 345) and 2291 age-and sex-matched controls were enrolled between 1998 and 2008, and followed to the end of 2011. Participants who developed dementia during the follow-up were identified. Both patients with bipolar disorder [hazard ratio (HR) 5.58, 95% confidence interval (CI) 4.26-7.32] and those with major depression (HR 3.02, 95% CI 2.46-3.70) had an increased risk of developing dementia in later life, after adjusting for demographic data and medical comorbidities. The sensitivity tests after excluding the 1-year (bipolar disorder: HR 4.73, 95% CI 3.50-6.35; major depression: HR 2.62, 95% CI 2.11-3.25) and 3-year (HR 3.92, 95% CI 2.78-5.54; HR 2.21, 95% CI 1.73-2.83, respectively) follow-up duration also revealed consistent findings. Furthermore, patients with bipolar disorder were associated with an 87% increased risk (HR 1.87, 95% CI 1.48-2.37) of subsequent dementia compared with patients with major depression. Midlife individuals with bipolar disorder or major depression were associated with an elevated risk of developing dementia in later life. Further studies may be required to clarify the underlying mechanisms among major depression, bipolar disorder, and dementia, and to investigate whether prompt intervention may decrease this risk.

    Anxiety disorders and anorexia nervosa are frequently acknowledged to be highly comorbid conditions, but still, little is known about the clinical and aetiological cohesion of specific anxiety diagnoses and anorexia nervosa. Using the comprehensive Danish population registers, we aimed to determine the risk of anorexia nervosa in patients with register-detected severe anxiety disorders. We also explored whether parental psychopathology was associated with offspring's anorexia nervosa. Anxiety disorders increased the risk of subsequent anorexia nervosa, with the highest risk observed in obsessive-compulsive disorder. Especially, male anxiety patients were at an increased risk for anorexia nervosa. Furthermore, an increased risk was observed in offspring of fathers with panic disorder. A diagnosis of an anxiety disorder, specifically obsessive-compulsive disorder, constitutes a risk factor for subsequent diagnosis of anorexia nervosa. These observations support the notion that anxiety disorders and anorexia nervosa share etiological mechanisms and/or that anxiety represents one developmental pathway to anorexia nervosa.

    Full Text Available Emotional content typically facilitates subsequent memory, known as the emotional enhancement effect. We investigated whether emotional content facilitates spatial and item memory in patients with Alzheimer's dementia (AD. Twenty-three AD patients, twenty-three healthy elderly, and twenty-three young adults performed a picture relocation task and a delayed recognition task with positive, negative, and neutral stimuli. AD patients showed a benefit in immediate spatial memory for positive pictures, while healthy young and older participants did not benefit from emotional content. No emotional enhancement effects on delayed item recognition were seen. We conclude that AD patients may have a memory bias for positive information in spatial memory. Discrepancies between our findings and earlier studies are discussed.

    Transcranial magnetic stimulation (TMS) has been used extensively to characterize motor system pathophysiology in Alzheimer's disease (AD) and other forms of dementia, as well to monitor the effects of certain pharmacological agents. Among the studies focusing on motor cortical excitability measures, the most consistent finding is a significant reduction of short-latency afferent inhibition (SAI) in AD and other forms of dementia in which the cholinergic system is affected, such as dementia with Lewy bodies. SAI evaluation may thus provide a reliable biomarker of cortical cholinergic dysfunction in dementias. Moreover, most TMS studies have demonstrated cortical hyperexcitability and asymptomatic motor cortex functional reorganization in the early stages of the disease. Integrated approaches utilizing TMS together with high-density EEG have indicated impaired cortical plasticity and functional connectivity across different neural networks in AD. Paired associative stimulation-induced plasticity has also been found to be abnormal in patients with AD. The development of novel noninvasive methods of brain stimulation, in particular repetitive TMS (rTMS) and transcranial direct current stimulation (tDCS), has increased the interest in neuromodulatory techniques as potential therapeutic tools for cognitive rehabilitation in AD. Preliminary studies have revealed that rTMS and tDCS can induce beneficial effects on specific cognitive functions in AD. Future studies are warranted to replicate and extend the initial findings. © 2013 Elsevier B.V. All rights reserved.

    During the late 20 th century numerical rating scales became central to the diagnosis of dementia and helped transform attitudes about its causes and prevalence. Concentrating largely on the development and use of the Blessed Dementia Scale, I argue that rating scales served professional ends during the 1960s and 1970s. They helped old age psychiatrists establish jurisdiction over conditions such as dementia and present their field as a vital component of the welfare state, where they argued that 'reliable modes of diagnosis' were vital to the allocation of resources. I show how these arguments appealed to politicians, funding bodies and patient groups, who agreed that dementia was a distinct disease and claimed research on its causes and prevention should be designated 'top priority'. But I also show that worries about the replacement of clinical acumen with technical and depersonalized methods, which could conceivably be applied by anyone, led psychiatrists to stress that rating scales had their limits and could be used only by trained experts.

    The aim of this study was to validate the reliability of the Chinese version of Addenbrooke's Cognitive Examination III (ACE-III) for detecting dementia. Furthermore, the present study compares the diagnostic accuracy of ACE-III with that of mini-mental state examination (MMSE). One hundred seventy-seven patients with dementia and 180 healthy controls were included in the study. The reliability of ACE-III was very good (α-coefficient = 0.888). There was a significant negative correlation between Clinical Dementia Rating Scale score and total ACE-III score. Further, there was a positive correlation between MMSE score and total ACE-III score. Age exerted a significant effect on total ACE-III score, memory score, and language score. In the present study, the cutoff score of 83 showed a sensitivity of 91.1% and a specificity of 83.1%. The present findings support that the Chinese version of ACE-III is a reliable assessment tool for dementia. Copyright © 2017 John Wiley & Sons, Ltd. Copyright © 2017 John Wiley & Sons, Ltd.

    Dementia is characterised by chronic, global, non-reversible deterioration in memory, executive function, and personality. Speech and motor function may also be impaired. We conducted a systematic review and aimed to answer the following clinical questions: What are the effects of treatments on cognitive symptoms of dementia (Alzheimer's, Lewy body, or vascular)? What are the effects of treatments on behavioural and psychological symptoms of dementia (Alzheimer's, Lewy body, or vascular)? We searched: Medline, Embase, The Cochrane Library, and other important databases up to July 2011 (Clinical Evidence reviews are updated periodically; please check our website for the most up-to-date version of this review). We included harms alerts from relevant organisations such as the US Food and Drug Administration (FDA) and the UK Medicines and Healthcare products Regulatory Agency (MHRA). We found 49 systematic reviews, RCTs, or observational studies that met our inclusion criteria. We performed a GRADE evaluation of the quality of evidence for interventions. In this systematic review, we present information relating to the effectiveness and safety of the following interventions: acetylcholinesterase inhibitors (donepezil, galantamine, rivastigmine), antidepressants (clomipramine, fluoxetine, imipramine, sertraline), antipsychotics (haloperidol, olanzapine, quetiapine, risperidone), aromatherapy, benzodiazepines (diazepam, lorazepam), cognitive behavioural therapy (CBT), cognitive stimulation, exercise, ginkgo biloba, memantine, mood stabilisers (carbamazepine, sodium valproate/valproic acid), music therapy, non-steroidal anti-inflammatory drugs (NSAIDs), omega 3 (fish oil), reminiscence therapy, and statins.

    Brain tissue analysis is necessary to confirm prion diseases. Clinically unsuspected cases may be identified through neuropathologic testing. National Alzheimer's Coordinating Center (NACC) Minimum and Neuropathologic Data Set for 1984 to 2005 were reviewed. Eligible patients had dementia, underwent autopsy, had available neuropathologic data, belonged to a currently funded Alzheimer's Disease Center (ADC), and were coded as having an Alzheimer's disease clinical diagnosis or a nonprion disease etiology. For the eligible patients with neuropathology indicating prion disease, further clinical information, collected from the reporting ADC, determined whether prion disease was considered before autopsy. Of 6000 eligible patients in the NACC database, 7 (0.12%) were clinically unsuspected but autopsy-confirmed prion disease cases. The proportion of patients with dementia with clinically unrecognized but autopsy-confirmed prion disease was small. Besides confirming clinically suspected cases, neuropathology is useful to identify unsuspected clinically atypical cases of prion disease. © The Author(s) 2015.

    Whether late-onset depression is a risk factor for or a prodrome of dementia remains unclear. We investigated the impact of depressive symptoms and early- v. late-onset depression on subsequent dementia in a cohort of elderly general-practitioner patients (n = 2663, mean age = 81.2 years). Risk for subsequent dementia was estimated over three follow-ups (each 18 months apart) depending on history of depression, particularly age of depression onset, and current depressive symptoms using proportional hazard models. We also examined the additive prediction of incident dementia by depression beyond cognitive impairment. An increase of dementia risk for higher age cut-offs of late-onset depression was found. In analyses controlling for age, sex, education, and apolipoprotein E4 genotype, we found that very late-onset depression (aged ≥ 70 years) and current depressive symptoms separately predicted all-cause dementia. Combined very late-onset depression with current depressive symptoms was specifically predictive for later Alzheimer's disease (AD; adjusted hazard ratio 5.48, 95% confidence interval 2.41-12.46, p < 0.001). This association was still significant after controlling for cognitive measures, but further analyses suggested that it was mediated by subjective memory impairment with worries. Depression might be a prodrome of AD but not of dementia of other aetiology as very late-onset depression in combination with current depressive symptoms, possibly emerging as a consequence of subjectively perceived worrisome cognitive deterioration, was most predictive. As depression parameters and subjective memory impairment predicted AD independently of objective cognition, clinicians should take this into account.

    Background Most clinical practice guidelines recommend screening for HCC in patients with cirrhosis. However, patients with compensated cirrhosis are often asymptomatic and may remain unrecognized for years. Aims To determine the extent to which cirrhosis is unrecognized in a US Veteran population with HCC and to evaluate the association between lack of cirrhosis recognition and stage of HCC at diagnosis. Methods We reviewed the electronic medical records of a random sample of HCC cases diagnosed in the national Veterans Affairs system between 2005 and 2011. We conducted multivariable analyses adjusting for patients’ demographics, comorbidity, etiology of underlying disease, and healthcare utilization including HCC surveillance. Results Of 1201 patients with HCC and cirrhosis, 24.6% had unrecognized cirrhosis prior to HCC diagnosis. Older patients (>65yr, odds ratio [OR] 2.32), African Americans (OR 1.93), patients with alcoholic or NAFLD liver disease (OR 1.69 and 4.77 respectively), HIV (OR 3.02), and fewer comorbidities (Deyo 0 vs. 3, OR 2.42) had significantly higher odds of having unrecognized cirrhosis than comparison groups. Furthermore, patients with unrecognized cirrhosis were 6.5 times more likely to have advanced stage HCC at diagnosis. The effect of cirrhosis recognition on HCC stage remained significant after adjusting for pre-specified covariates (OR 3.37). Conclusions In one fourth of patients, cirrhosis was unrecognized prior to HCC diagnosis, and this group was significantly more likely to have advanced stage HCC. These findings emphasize the importance of timely evaluation for cirrhosis in at-risk populations as a critical step to improving outcomes for HCC patients. PMID:26784271

    Many older adults continue to drive following dementia diagnosis, with medical providers increasingly likely to be involved in addressing such safety concerns. This study examined electronic medical record (EMR) documentation of driving safety for veterans with dementia (N = 118) seen in Veterans Affairs primary care and interdisciplinary geriatrics clinics in one geographic region over a 10-year period. Qualitative directed content analysis of retrospective EMR data. Assessment of known risk factors or subjective concerns for unsafe driving were documented in fewer than half of observed cases; specific recommendations for driving safety were evident for a minority of patients, with formal driving evaluation the most frequently documented recommendation by providers. Utilizing data from actual clinical encounters provides a unique snapshot of how driving risk and safety concerns are addressed for veterans with dementia. This information provides a meaningful frame of reference for understanding potential strengths and possible gaps in how this important topic area is being addressed in the course of clinical care. The EMR is an important forum for interprofessional communication, with documentation of driving risk and safety concerns an essential element for continuity of care and ensuring consistency of information delivered to patients and caregivers.

As such, and considering the substantial challenges EOD presents to the patient, caregivers, and health care providers, this study sought to investigate the mechanism of care delivered to these patients. A medical record chart review was conducted for 85 patients attending a memory disorder unit who initially presented to rule out EOD as a working diagnosis. The results suggest that while the majority of these patients received an extensive work-up and were heavily medicated, they remained at home, where they lacked adequate age-related services and could not be placed, despite the crippling caregiver burden. This manuscript is a platform to discuss our current system limitations in the care of these patients with an eye on new opportunities for this challenging group.Keywords: early onset dementia, social work, services, caregiving

    This study aims to examine what types of home care services and housing are granted to people with a dementia diagnosis and how these types are associated with socio-demographic factors (sex, age, marital status, native or foreign born, and regional area). A cross-sectional study of all people diagnosed with dementia in three Swedish counties was conducted from the medical records in 2012. Logistic regression analysis was carried out to investigate associations between home care services and housing and socio-demographic variables. In total, 17,405 people had a dementia diagnosis, and the majority were women, aged 80+ years, and unmarried. Some 72% were living in ordinary housing and 28% lived in special housing. Of those who lived in ordinary housing, 50% did not receive any home care service. Not receiving any type of home care services was less common for older people and was also associated with being married and living in rural municipalities. The most common home care services granted were home help and personal care. Special housing was more common for older people, unmarried persons, and those living in rural municipalities. Most people with a dementia diagnosis were living in ordinary housing, and, surprisingly, half of those did not receive any type of home care service. This knowledge is essential for making the living conditions and needs of people living with dementia more visible and to provide good home care services for people with dementia and their families.

    Full Text Available Aims: To pilot a neuropsychological battery for diagnosing dementia and provide normative scores in an elderly Sri Lankan sample. Materials and Methods: Consecutive subjects over the age of 60 yrs were administered tests assessing the individual domains of language, verbal episodic memory, visual perceptuospatial skills and executive functions in the Sinhala language. Results: There were a total of 230 subjects in the final sample. The mean age of the entire sample was 69 years, mean education level was 12 years and the sample comprised 53% female. One-month test-retest reliability ranged from 0.71 to 0.85 for the various tests. Most tests were significantly influenced by age and education level but not gender. The exceptions to this were some language subtests (repetition, grammar comprehension and word picture matching and two tests of executive functioning (maze completion and alternate target cancellation, which were uninfluenced by age. The subtests where ceiling performance was attained by almost all subjects were repetition, grammar comprehension and word picture matching from the language domain, dot position discrimination from the visuospatial domain and maze completion test from the executive function domain. Scores for various tests after stratifying subjects by age and educational level are given. Conclusions: The tests were well received and could provide a basis for cognitive profiling in similar settings elsewhere.

    Among the non-motor features of Parkinson's disease (PD), cognitive impairment is one of the most troublesome problems. Highly sensitive and specific screening instruments for detecting dementia in PD (PDD) are required in the clinical practice. In our study we evaluated the sensitivity and specificity of different neuropsychological tests (Addenbrooke's Cognitive Examination, ACE; Frontal Assessment Battery, FAB and Mattis Dementia Rating Scale, MDRS) in 73 Parkinson's disease patients without depression. By receiver operating characteristic curve analysis, these screening instruments were tested against the recently established clinical diagnostic criteria of PDD. Best cut-off score for ACE to identify PDD was 80 points (sensitivity = 74.0%, specificity = 78.1%). For FAB the most optimal cut-off value was 12 points (sensitivity = 66.3%, specificity = 72.2%); whereas for MDRS it was 125 points (sensitivity = 89.8%, specificity = 98.3%). Among the examined test batteries, MDRS had the best clinicometric profile for detecting PDD. Although the types of applied screening instruments might differ from movement disorder clinic to clinic within a country, determination of the most specific and sensitive test for the given population remains to be an important task. Our results demonstrated that the specificity and sensitivity of MDRS was better than those of ACE, FAB and MMSE in Hungary. However, further studies with larger sample size and more uniform criteria for participation are required to determine the most suitable screening instrument for cognitive impairment.

    The Addenbrooke's Cognitive Examination (ACE) is a valid dementia-screening test that is a simple and effective instrument. We aimed to assess the diagnostic accuracy of the Korean version of the ACE (K-ACE) in a Korean population. A total of 115 subjects (50 with Alzheimer's dementia [AD], 26 with mild cognitive impairment [MCI], and 39 controls) who visited the Neurology Outpatient Clinic of Seoul Medical Center were included. The ACE was translated and modified to create the K-ACE. The sensitivity, specificity, area under the curve, reliability, and Verbal-Language/Orientation-Memory ratio were evaluated. The receiver-operating characteristic (ROC) curve was used to determine the optimal cutoff score in screening for dementia. The ROC curves showed the superiority of the K-ACE over the Korean Mini-Mental Status Examination in the diagnosis of AD and MCI. The optimal cutoff of the K-ACE for the identification of AD was 68/69, which had a sensitivity of 90% and a specificity of 84%. The K-ACE is a short, reliable, and valid neuropsychological test battery used to screen for dementia in the Korean elderly.

    Full Text Available The main objective of the present study was to evaluate the diagnostic value (clinical application of brain measures and cognitive function. Alzheimer and multiinfarct patients (N = 30 and normal subjects over the age of 50 (N = 40 were submitted to a medical, neurological and cognitive investigation. The cognitive tests applied were Mini-Mental, word span, digit span, logical memory, spatial recognition span, Boston naming test, praxis, and calculation tests. The brain ratios calculated were the ventricle-brain, bifrontal, bicaudate, third ventricle, and suprasellar cistern measures. These data were obtained from a brain computer tomography scan, and the cutoff values from receiver operating characteristic curves. We analyzed the diagnostic parameters provided by these ratios and compared them to those obtained by cognitive evaluation. The sensitivity and specificity of cognitive tests were higher than brain measures, although dementia patients presented higher ratios, showing poorer cognitive performances than normal individuals. Normal controls over the age of 70 presented higher measures than younger groups, but similar cognitive performance. We found diffuse losses of tissue from the central nervous system related to distribution of cerebrospinal fluid in dementia patients. The likelihood of case identification by functional impairment was higher than when changes of the structure of the central nervous system were used. Cognitive evaluation still seems to be the best method to screen individuals from the community, especially for developing countries, where the cost of brain imaging precludes its use for screening and initial assessment of dementia.

    The Addenbrooke's Cognitive Examination III (ACE-III), an adaptation of the ACE cognitive screening test, has been demonstrated to have high sensitivity and specificity in detecting cognitive impairment in patients with dementia and other neurological and psychiatric disorders. Although the Spanish-language version of the ACE-III has already been validated in Spain, it is yet to be validated in Latin America. The aim of this study was to validate the ACE-III test in an Argentinean and Chilean population. ACE-III was administered to 70 patients with Alzheimer disease, 31 patients with behavioural variant frontotemporal dementia, and a control group of 139 healthy volunteers. Participants were recruited at centres in both countries. The Spanish-language version of ACE-III was found to have good internal consistency (Cronbach's alpha=0.87).

    Full Text Available Introduction: Neurocognitive dysfunction is a detrimental complication of HIV infection. In this study we attempt to characterize the pattern of cognitive dysfunction in a sample of Nigerian patients with newly diagnosed HIV infection. Methods: We conducted a prospective study in which 50 patients with newly diagnosed HIV infection were studied along with 50 normal control subjects. The participants were evaluated with the medical history, general, physical and neurological examination. Laboratory evaluation and chest X-Ray were done for all patients. The Community Screening Interview for Dementia (CSID questionnaire was administered to all the study participants. Results: About 70% of the patients were in advanced disease stage. The mean age (SD of the patients and controls in years were 36.44±8.22 and 35.40±11.53 respectively. More than half (56% of the patients had secondary level of education (12years of education. About 20% of the patients had severe neurocognitive impairment while 48% had minor neurocognitive disorder. The patients with HIV infection performed poorly in the domains of language, memory, orientation, attention/calculation and praxis relative to controls (p0.05 but the presence of opportunistic infections had negative impact on the performances on orientation and total CSID scores in the patients with HIV infection (p<0.05. Conclusion: Patients with newly diagnosed HIV infection have poor cognitive functions when compared to normal controls and some presence of opportunistic infections in the patient is a significant risk factor for cognitive impairment.

    We aimed to analyze the construct and concurrent validity of the Rapid Visual Information Processing (RVP), Paired Associates Learning (PAL), Reaction Time (RTI), and Spatial Working Memory (SWM) tests from the Cambridge Neuropsychological Test Automated Battery (CANTAB®). Inclusion criteria were checked in a first session. The CANTAB and additional pencil-and-paper tests were administered within 1 week. The participants (aged 69-96 years) were 137 Portuguese adults without neuropsychiatric diagnoses and 37 adults with mild-to-moderate Alzheimer's disease dementia. Comparisons were made between the CANTAB tests and between these tests and the Rey Complex Figure Test (RCFT), Verbal Fluency (VF) test, and some Wechsler Memory Scale-III and Wechsler Adult Intelligence Scale-III subtests. Most intra-test correlations were stronger than the CANTAB inter-test correlations. The RVP correlated more with VF animals (.44), the PAL with RCFT immediate recall (-.52), the RTI with RVP mean latency (.42), and the SWM with Spatial Span backward (-.39).

    Effective management for type 2 diabetes mellitus (DM) can slow the progression of kidney outcomes and reduce hospital admissions. Better continuity of care (COC) was found to improve patients' adherence and self-management. This study examined the associations between COC, hospitalization, and end-stage renal disease (ESRD) in DM patients. In the cohort study, data from 1996 to 2012 were retrieved from the Longitudinal Health Insurance Database, using inverse probability weighted analysis. A total of 26,063 patients with newly diagnosed type 2 DM who had been treated with antihyperglycemic agents were included. COC is to assess the extent to which a DM patient visited the same physician during the study period. This study categorized COC into 3 groups - low, intermediate, and high, - according to the distribution of scores in our sample. The number of ESRD patients in the high, intermediate, and low COC groups were 92 (22.33%), 130 (31.55%), and 190 (46.12%), respectively, and the mean follow-up periods for the 3 groups were 7.13, 7.12, and 7.27 years, respectively. After using inverse probability weighting, the intermediate and low COC groups were significantly associated with an increased risk of ESRD compared with the high COC group (adjusted hazard ratio (aHR) 1.36 [95% CI, 1.03-1.80] and aHR 1.76 [95% CI, 1.35-2.30], respectively). The intermediate and low COC groups were also significantly associated with the subsequent hospitalization compared with the high COC group (aHR 1.15 [95% CI, 0.99-1.33] and aHR 1.72 [95% CI, 1.50-1.97], respectively). COC is related to ESRD onset and subsequent hospitalization among patients with DM. This study suggested that when DM patients keep visiting the same physician for managing their diseases, the progression of renal disease can be prevented.

    Premorbid personality characteristics could have a pathoplastic effect on behavioral symptoms and personality changes related to neurodegenerative diseases. Patients with personality disorders, in particular of the dramatic cluster, may present functional frontolimbic abnormalities. May these neurobiological vulnerabilities linked to a premorbid personality disorder predispose or represent a risk factor to subsequently develop a neurodegenerative disorder? Are subjects with personality disorders more at risk to develop a dementia than mentally healthy subjects? This topic is discussed presenting the clinical case of a patient who suffered of a probable Narcissistic Personality Disorder and subsequently developed a clinically diagnosed Frontotemporal Dementia.

    BACKGROUND: Early-onset dementia (EOD) is a rare condition, with an often atypical clinical presentation, and it may therefore be challenging to diagnose. Specialized memory clinics vary in the type of patients seen, diagnostic procedures applied, and the pharmacological treatment given. The aim...... of this study was to investigate quality-of-care indicators in subjects with EOD from 3 tertiary memory clinics in 3 European countries. METHODS: We included 1325 newly diagnosed EOD patients, ages 65 years or younger, between January 1, 2007 and December 31, 2013, from the Danish Dementia Registry...... (Rigshospitalet, Copenhagen), the Swedish Dementia Registry ("SveDem", Karolinska University Hospital, Stockholm), and the Amsterdam Dementia Cohort (VU University Medical Center). RESULTS: The frequency of EOD among all dementia patients was significantly lower in Copenhagen (410, 20%) and Stockholm (284, 21...

    To determine if serum magnesium levels are associated with the risk of all-cause dementia and Alzheimer disease. Within the prospective population-based Rotterdam Study, we measured serum magnesium levels in 9,569 participants, free from dementia at baseline (1997-2008). Participants were subsequently followed up for incident dementia, determined according to the DSM-III-R criteria, until January 1, 2015. We used Cox proportional hazard regression models to associate quintiles of serum magnesium with incident all-cause dementia. We used the third quintile as a reference group and adjusted for age, sex, Rotterdam Study cohort, educational level, cardiovascular risk factors, kidney function, comorbidities, other electrolytes, and diuretic use. Our study population had a mean age of 64.9 years and 56.6% were women. During a median follow-up of 7.8 years, 823 participants were diagnosed with all-cause dementia. Both low serum magnesium levels (≤0.79 mmol/L) and high serum magnesium levels (≥0.90 mmol/L) were associated with an increased risk of dementia (hazard ratio [HR] 1.32, 95% confidence interval [CI] 1.02-1.69, and HR 1.30, 95% CI 1.02-1.67, respectively). Both low and high serum magnesium levels are associated with an increased risk of all-cause dementia. Our results warrant replication in other population-based studies. © 2017 American Academy of Neurology.

    Most approaches to the detection of presymptomatic or prodromal Alzheimer's disease require the costly collection and analysis of biological samples or neuroimaging measurements. The Dementia Risk Assessment (DRA) was developed to facilitate this detection by collecting self-report and proxy-report of dementia risk variables and episodic memory performance on a free Internet website. We now report two validation studies. In Study 1, 130 community-residing older adults seeking memory screening at senior health fairs were tested using the Mini-Cog, and were then observed while taking the DRA. They were compared to a demographically-matched subsample from our anonymous Internet sample. Participants seeking memory screening had more dementia risk factors and obtained lower scores on the DRA's recognition memory test (RMT) than their Internet controls. In addition, those who failed the Mini-Cog obtained much lower scores on the RMT than those who passed the Mini-Cog. In Study 2, 160 older adults seeking evaluation of cognitive difficulties took the DRA prior to diagnostic evaluations at outpatient dementia clinics. Patients who ultimately received the diagnosis of a dementia syndrome scored significantly lower on the RMT than those diagnosed with other conditions or deemed normal. Lower education, family history of dementia, presence of hypercholesterolemia and diabetes, and memory test score distinguished the dementia and no-dementia groups with around 82% accuracy. In addition, score on the RMT correlated highly with scores on other instruments widely used to detect cognitive decline. These findings support the concurrent validity of the DRA for detecting prevalent cognitive impairment. Prospective studies of cognitively normal persons who subsequently develop dementia will be necessary to establish its predictive validity.

    Cosmetic breast implants may impair the ability to detect breast cancers. The aims of this study were to examine whether implants and implant characteristics are associated with more advanced breast tumors at diagnosis and poorer survival. Study population includes all invasive breast cancer cases diagnosed during follow-up of the large Canadian Breast Implant Cohort. A total of 409 women with cosmetic breast implants and 444 women with other cosmetic surgery were diagnosed with breast cancer. These women were compared for stage at diagnosis using multinomial logistic regression models. Cox proportional hazards regression models were used for breast cancer-specific mortality analyses. Comparisons were also conducted according to implant characteristics. Compared with women with other cosmetic surgery, those with cosmetic breast implants had at later stage breast cancer diagnosis (OR of having stage III/IV vs. stage I at diagnosis: 3.04, 95% confidence interval (CI): 1.81-5.10; P breast cancer-specific mortality rate for women with breast implants relative to surgical controls was observed (HR = 1.32, 95% CI: 0.94-1.83, P = 0.11). No statistically significant differences in stage and breast cancer mortality were observed according to implant characteristics. At diagnosis, breast cancers tended to be at more advanced stages among women with cosmetic breast implants. Breast cancer-specific survival was lower in these women although the reduction did not reach statistical significance. Further investigations of the effect of breast implants on breast cancer prognosis are warranted. 2012 AACR

  20. Do continued antidepressants protect against dementia in patients with severe depressive disorder?

    2011-11-01

    Studies on humans show that depressive disorder is associated with an increased risk of developing cognitive dysfunction, and animal studies suggest that antidepressants may have neuroprotective abilities. On the basis of these observations, it was hypothesized that treatment with antidepressants may decrease the risk of developing dementia in patients with depression. We investigated whether continued treatment with antidepressants is associated with a decreased rate of dementia in a population of patients discharged from psychiatric healthcare service with a diagnosis of depression. We used register data on all prescribed antidepressants in all patients discharged from psychiatric healthcare service with a diagnosis of depression and with subsequent diagnoses of dementia in Denmark from 1995 to 2005. A total of 37 658 patients with a diagnosis of depression at their first psychiatric contact and who were exposed to antidepressants after discharge were included in the study. A total of 2007 patients (5.3%) were subsequently diagnosed with dementia of any kind. The rate of dementia decreased during periods of two or more prescriptions of older antidepressants compared with the period of only one prescription of older antidepressants [relative risk (RR)=0.83 (95% confidence interval (CI)=0.70-0.98)]. This finding was replicated with Alzheimer's disease as the outcome [RR=0.66 (95% CI=0.47-0.94)] but not with dementia of other kinds as the outcome [RR=0.88 (95% CI=0.73-1.06)]. In contrast, during periods of continued use of selective serotonin reuptake inhibitors or newer nonselective serotonin reuptake inhibitors, the rate of dementia was not decreased, regardless of the subtype of dementia. It was concluded that continued long-term treatment with older antidepressants is associated with a reduced rate of dementia in patients treated in psychiatric healthcare settings, whereas continued treatment with other kinds of antidepressants is not.

      We report three cases of Landau-Kleffner syndrome (LKS) in children (two females, one male) in whom diagnosis was delayed because the sleep electroencephalography (EEG) was initially normal.   Case histories including EEG, positron emission tomography findings, and long-term outcome were reviewed.   Auditory agnosia occurred between the age of 2 years and 3 years 6 months, after a period of normal language development. Initial awake and sleep EEG, recorded weeks to months after the onset of language regression, during a nap period in two cases and during a full night of sleep in the third case, was normal. Repeat EEG between 2 months and 2 years later showed epileptiform discharges during wakefulness and strongly activated by sleep, with a pattern of continuous spike-waves during slow-wave sleep in two patients. Patients were diagnosed with LKS and treated with various antiepileptic regimens, including corticosteroids. One patient in whom EEG became normal on hydrocortisone is making significant recovery. The other two patients did not exhibit a sustained response to treatment and remained severely impaired.   Sleep EEG may be normal in the early phase of acquired auditory agnosia. EEG should be repeated frequently in individuals in whom a firm clinical diagnosis is made to facilitate early treatment. © The Authors.

    To investigate whether greater cardiovascular fitness in midlife is associated with decreased dementia risk in women followed up for 44 years. A population-based sample of 1,462 women 38 to 60 years of age was examined in 1968. Of these, a systematic subsample comprising 191 women completed a stepwise-increased maximal ergometer cycling test to evaluate cardiovascular fitness. Subsequent examinations of dementia incidence were done in 1974, 1980, 1992, 2000, 2005, and 2009. Dementia was diagnosed according to DSM-III-R criteria on the basis of information from neuropsychiatric examinations, informant interviews, hospital records, and registry data up to 2012. Cox regressions were performed with adjustment for socioeconomic, lifestyle, and medical confounders. Compared with medium fitness, the adjusted hazard ratio for all-cause dementia during the 44-year follow-up was 0.12 (95% confidence interval [CI] 0.03-0.54) among those with high fitness and 1.41 (95% CI 0.72-2.79) among those with low fitness. High fitness delayed age at dementia onset by 9.5 years and time to dementia onset by 5 years compared to medium fitness. Among Swedish women, a high cardiovascular fitness in midlife was associated with a decreased risk of subsequent dementia. Promotion of a high cardiovascular fitness may be included in strategies to mitigate or prevent dementia. Findings are not causal, and future research needs to focus on whether improved fitness could have positive effects on dementia risk and when during the life course a high cardiovascular fitness is most important.

    This study examined how awareness of diagnostic label impacted self-reported quality of life (QOL) in persons with varying degrees of cognitive impairment. Older adults (n = 259) with normal cognition, Mild Cognitive Impairment (MCI), or mild Alzheimer's disease dementia (AD) completed tests of cognition and self-report questionnaires that assessed diagnosis awareness and multiple domains of QOL: cognitive problems, activities of daily living, physical functioning, mental wellbeing, and perceptions of one's daily life. We compared measures of QOL by cognitive performance, diagnosis awareness, and diagnostic group. Persons with MCI or AD who were aware of their diagnosis reported lower average satisfaction with daily life (QOL-AD), basic functioning (BADL Scale), and physical wellbeing (SF-12 PCS), and more difficulties in daily life (DEM-QOL) than those who were unaware (all p ≤ .007). Controlling for gender, those expecting their condition to worsen over time reported greater depression (GDS), higher stress (PSS), lower quality of daily life (QOL-AD, DEM-QOL), and more cognitive difficulties (CDS) compared to others (all p cognitive impairment. © The Author 2017.

    Patients with late-onset depression (LOD) have been reported to run a higher risk of subsequent dementia. The present study was conducted to assess whether statins can reduce the risk of dementia in these patients. We used the data from National Health Insurance of Taiwan during 1996-2009. Standardized Incidence Ratios (SIRs) were calculated for LOD and subsequent dementia. The criteria for LOD diagnoses included age ≥65 years, diagnosis of depression after 65 years of age, at least three service claims, and treatment with antidepressants. The time-dependent Cox proportional hazards model was applied for multivariate analyses. Propensity scores with the one-to-one nearest-neighbor matching model were used to select matching patients for validation studies. Kaplan-Meier curve estimate was used to measure the group of patients with dementia living after diagnosis of LOD. Totally 45,973 patients aged ≥65 years were enrolled. The prevalence of LOD was 12.9% (5,952/45,973). Patients with LOD showed to have a higher incidence of subsequent dementia compared with those without LOD (Odds Ratio: 2.785; 95% CI 2.619-2.958). Among patients with LOD, lipid lowering agent (LLA) users (for at least 3 months) had lower incidence of subsequent dementia than non-users (Hazard Ratio = 0.781, 95% CI 0.685-0.891). Nevertheless, only statins users showed to have reduced risk of dementia (Hazard Ratio = 0.674, 95% CI 0.547-0.832) while other LLAs did not, which was further validated by Kaplan-Meier estimates after we used the propensity scores with the one-to-one nearest-neighbor matching model to control the confounding factors. Statins may reduce the risk of subsequent dementia in patients with LOD.

    Increased prevalence of lifestyle risk factors or shared etiology may underlie the association between schizophrenia and the subsequent risk of dementia. We explored the association between having a spouse with schizophrenia and the risk of dementia. We found a positive relationship between having a spouse with schizophrenia and vascular dementia in individuals without a mental disorder themselves but no association between having a spouse with schizophrenia and Alzheimer's dementia. As spouses share environmental risk factors and lifestyle, this might suggest that the excess risk of dementia in probands with schizophrenia could be ascribed to the unhealthy living environment among individuals with schizophrenia.

    To examine level of and change in cognitive status using the Mini-Mental State Examination (MMSE) in relation to dementia, mortality, education, and sex in late nonagenarians. Three-year longitudinal study with examinations at ages 97, 99, and 100. Trained psychiatric research nurses examined participants at their place of living. A representative population-based sample of 97-year-old Swedes (N = 591; 107 men, 484 women) living in Gothenburg, Sweden. A Swedish version of the MMSE was used to measure cognitive status. Geriatric psychiatrists diagnosed dementia according to the Diagnostic and Statistical Manual of Mental Disorders, Third Edition, Revised. Mixed models were fitted to the data to model the longitudinal relationship between MMSE score and explanatory variables. Individuals with dementia between age 97 and 100 had lower mean MMSE scores than those without dementia. Those who died during the 3-year follow-up had lower MMSE scores than those who survived. MMSE scores at baseline did not differ between those without dementia and those who developed dementia during the 3-year follow-up. Participants with more education had higher MMSE scores, but there was no association between education and linear change. MMSE score is associated with dementia and subsequent mortality even in very old individuals, although the preclinical phase of dementia may be short in older age. Level of education is positively associated with MMSE score but not rate of decline in individuals approaching age 100. © 2017, Copyright the Authors Journal compilation © 2017, The American Geriatrics Society.

    This study examined the effect of lifelong bilingualism on maintaining cognitive functioning and delaying the onset of symptoms of dementia in old age. The sample was selected from the records of 228 patients referred to a Memory Clinic with cognitive complaints. The final sample consisted of 184 patients diagnosed with dementia, 51% of whom were bilingual. The bilinguals showed symptoms of dementia 4 years later than monolinguals, all other measures being equivalent. Additionally, the rate of decline in Mini-Mental State Examination (MMSE) scores over the 4 years subsequent to the diagnosis was the same for a subset of patients in the two groups, suggesting a shift in onset age with no change in rate of progression.

    We sought to determine the type-specific prevalence of dementia and its risk factors in elderly persons from the Japanese community of Hisayama. We studied the prevalence of dementia in 887 Hisayama residents (353 men and 534 women) aged 65 years or older (screening rate, 94.6%) using various items of clinical information, neurological examination, and dementia scales. We also studied brain morphology in 50 of 59 determined to have dementia by computed tomography or autopsy during the subsequent 54-month period. Factors relevant to dementia were compared between 27 patients with vascular dementia and 789 control subjects without dementia in a retrospective fashion. The prevalence rate of dementia among Hisayama residents aged 65 or older was estimated at 6.7%, with a females to males ratio of 1:2. Among 50 cases of dementia in which brain morphology was examined, the frequency of vascular dementia was 56%; this rate was 2.2 times higher than that for senile dementia of the Alzheimer type. Aging, hypertension, electrocardiographic abnormalities, and high hematocrit were significantly (p less than 0.05) and independently associated with the occurrence of vascular dementia. Prevalence of dementia among the Hisayama residents was relatively identical to that previously reported, but vascular dementia was more predominant. Risk factors for vascular dementia were similar to those for lacunar infarcts. Control of hypertension may be a key to reducing dementia among the Japanese population.

    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: With increasing life expectancy across the world, the number of elderly people at risk of developing dementia is growing rapidly. Thus, progressive neurodegenerative disorders such as dementia represent a growing public health concern. These diseases are characterized by a progressive loss in most of the cognitive functions. The promise, possibly in a near future, of disease-modifying therapies has made the characterization of the early stages of dementia a topic of major interest. The assessment of these early stages is a challenge for neuroimaging studies. In order to conceive prevention trials; it is of major outcome to fully understand the mechanisms of the cognitive system impairment and its evolution, with a particular reference to the symptomatic pre-dementia stage, when subjects just begin to depart from normality. In this article we review recent progress in neuroimaging, and their potentiality for increasing a diagnostic accuracy. (author)

    Many cardiovascular risk factors are shown to increase the risk of dementia and Alzheimer's disease (AD), but the impact of heart disease on later development of dementia is still unclear. The aim of the study was to investigate the long-term risk of dementia and Alzheimer's disease (AD) related to midlife and late-life atrial fibrillation (AF), heart failure (HF), and coronary artery disease (CAD) in a population-based study with a follow-up of over 25 years. Cardiovascular Risk Factors, Aging and Dementia (CAIDE) study includes 2000 participants who were randomly selected from four separate, population-based samples originally studied in midlife (1972, 1977, 1982, or 1987). Re-examinations were carried out in 1998 and 2005-2008. Altogether 1,510 (75.5%) persons participated in at least one re-examination, and 127 (8.4%) persons were diagnosed with dementia (of which 102 had AD). AF in late-life was an independent risk factor for dementia (HR 2.61, 95% CI 1.05-6.47; p = 0.039) and AD (HR 2.54, 95% CI 1.04-6.16; p = 0.040) in the fully adjusted analyses. The association was even stronger among the apolipoprotein E (APOE) ε4 non-carriers. Late-life HF, but not CAD, tended to increase the risks as well. Heart diseases diagnosed at midlife did not increase the risk of later dementia and AD. Late-life heart diseases increase the subsequent risk of dementia and AD. Prevention and effective treatment of heart diseases may be important also from the perspective of brain health and cognitive functioning.

    Depression is associated with increased risk of subsequent development of dementia; however, the nature of the association is still poorly understood. The purpose of the review was based on recent studies to discuss whether depression is a prodromal state of dementia or an independent risk factor for dementia, as well as to discuss how the type of depression, the type of dementia, and antidepressant treatment influence the association. Findings from recent studies suggest that some forms of depressive illness, for example early-onset depression before age 65 years and recurrent depression, may constitute long-term risk factors for development of dementia, whereas the onset of more recent depressive symptoms may reflect a prodromal phase of dementia. It is not clear whether specific subtypes of depression correspond to specific types of dementia. Recent studies suggest that long-term treatment with antidepressants may decrease the risk of developing some types of dementia, depending on the type of depressive disorder. This review has shown that the type of depression and dementia, as well as the effect of drug treatment, has to be considered to improve knowledge on the association between depression and dementia.

    1999-01-01

    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. The net cost of dementia is the difference in cost between those with dementia and the matched controls and amounts on average to DKK 77,000 per person per year. However, priority setting cannot be based on the cost of dementia per se, but only on the cost of a specific dementia intervention compared to its health benefit.

    The Dementia Risk Assessment (DRA) is an online tool consisting of questions about known risk factors for dementia, a novel verbal memory test, and an informant report of cognitive decline. Its primary goal is to educate the public about dementia risk factors and encourage clinical evaluation where appropriate. In Study 1, more than 3,000 anonymous persons over age 50 completed the DRA about themselves; 1,000 people also completed proxy reports about another person. Advanced age, lower education, male sex, complaints of severe memory impairment, and histories of cerebrovascular disease, Parkinson's disease, and brain tumor all contributed significantly to poor memory performance. A high correlation was obtained between proxy-reported decline and actual memory test performance. In Study 2, 52 persons seeking first-time evaluation at dementia clinics completed the DRA prior to their visits. Their responses (and those of their proxy informants) were compared to the results of independent evaluation by geriatric neuropsychiatrists. The 30 patients found to meet criteria for probable Alzheimer's disease, vascular dementia, or frontotemporal dementia differed on the DRA from the 22 patients without dementia (most other neuropsychiatric conditions). Scoring below criterion on the DRA's memory test had moderately high predictive validity for clinically diagnosed dementia. Although additional studies of larger clinical samples are needed, the DRA holds promise for wide-scale screening for dementia risk.

    Due to a significant overlap of the two syndromes, differentiation of degenerative dementia of the Alzheimer-type from vascular dementia may be difficult even when imaging studies are available. White matter changes occur in many patients suffering from Alzheimer's disease. Little is known about the impact of white matter changes on the course and clinical presentation of Alzheimer's disease. High sensitivity of MRI in the detection of white matter alterations may account for over-diagnosing vascular dementia. The clinical significance of white matter alterations in dementia is still a matter of debate. The article reviews current concepts about the role of white matter alterations in dementia. (orig.)

    With an increasingly aging population we are faced with the problem of an increasing number of dementia patients. In addition to clinical, neuropsychological and laboratory procedures, MRI plays an important role in the early diagnosis of dementia. In addition to various morphological changes functional changes can also help in the diagnosis and differential diagnosis of dementia. Overall the diagnosis of dementia can be improved by using parameters from MR spectroscopy. This article focuses on MR spectroscopic changes in the physiological aging process as well as on changes in mild cognitive impairment a precursor of Alzheimer's dementia, in Alzheimer's dementia, frontotemporal dementia, vascular dementia and Lewy body dementia.

    Although numerous studies have assessed cognitive dysfunction in patients with schizophrenia, very few have focused on the diagnosis of dementia. Our objectives were to accurately diagnose dementia in a cohort of middle-aged patients with schizophrenia and to assess the type of dementia. 96 patients with schizophrenia (46 inpatients and 50 outpatients), aged 50 to 70 years, underwent a psychiatric, neurological, and neuropsychological evaluation at baseline and after a 20-month follow-up. We established a 3-step procedure: 1) diagnose dementia according to the DSM-IV criteria, using the Mattis Dementia Rating and Activities of Daily Living scales; 2) characterize dementia using brain imaging, perfusion by 99mTc-ECD-SPECT and laboratory tests including Alzheimer's disease cerebrospinal fluid biomarkers; and 3) search for genetic determinants. Fourteen patients fulfilled the diagnostic criteria of dementia. Four were diagnosed with possible or probable behavioral-variant frontotemporal dementia (bvFTD), two with probable Alzheimer's disease, two with probable vascular dementia (including one due to CADASIL), one with CNS inflammatory disease, and six could not be fully characterized. The diagnosis of dementia in middle-aged patients with schizophrenia is challenging but possible, using a multistep procedure. The most frequent condition, bvFTD, could reflect the presence of an evolutive neurodegenerative process in some patients.

    Dementia is a chronic loss of neurocognitive function that is progressive and irreversible. Although rare, dural arteriovenous fistulas (DAVFs) could present with a rapid decline in neurocognitive function with or without Parkinson-like symptoms. DAVFs represent a potentially treatable and reversible cause of dementia. Here, we report the case of an elderly woman diagnosed with a DAVF after presenting with new-onset seizures, deteriorating neurocognitive function, and Parkinson-like symptoms.

    Full Text Available Background: Social relations and depressive symptoms are intertwined. They both predict subsequent dementia, but only few studies on the association between social life aspects and subsequent dementia exist. Methods: The risk of subsequent dementia was estimated over 2 follow-up assessments, each 18 months apart, depending on leisure activity, social support (general scale and the 3 factors emotional support, practical support, and social integration, and depressive symptoms, using proportional hazard models in a cohort of elderly patients (n = 2,300, with a mean age of 82.45 years recruited for the study by their general practitioners. Results: Higher depressive symptoms and lower cognitive and physical activity were associated with an increased risk of subsequent all-cause dementia and Alzheimer's dementia (AD. While neither social engagement nor the general social support scale was associated with subsequent dementia, a higher level of social integration was associated with a lower dementia risk. In combined models, the results for activity variables remained similar, but the strength of the association between depressive symptoms and the subsequent risk of dementia decreased, and the association with social integration disappeared. Conclusions: Depressive symptoms increased and activity variables decreased the risk of subsequent dementia; however, activity variables, namely cognitive and physical activity, partly mediated the effect of depressive symptoms on the subsequent risk of all-cause dementia and AD. In many cases, social support was not associated with a risk of subsequent dementia.

    Determinants for undetected dementia and late-life depression have been not well studied. To investigate risk factors for undetected dementia and depression in older communities. Using the method of the 10/66 algorithm, we interviewed a random sample of 7072 participants aged ≥60 years in six provinces of China during 2007-2011. We documented doctor-diagnosed dementia and depression in the interview. Using the validated 10/66 algorithm we diagnosed dementia (n = 359) and depression (n = 328). We found that 93.1% of dementia and 92.5% of depression was undetected. Both undetected dementia and depression were significantly associated with low levels of education and occupation, and living in a rural area. The risk of undetected dementia was also associated with 'help available when needed', and inversely, with a family history of mental illness and having functional impairment. Undetected depression was significantly related to female gender, low income, having more children and inversely with having heart disease. Older adults in China have high levels of undetected dementia and depression. General socioeconomic improvement, associated with mental health education, targeting high-risk populations are likely to increase detection of dementia and depression in older adults, providing a backdrop for culturally acceptable service development.

    Full Text Available Abstract Background This study describes the prevalence of dementia and major dementia subtypes in Spanish elderly. Methods We identified screening surveys, both published and unpublished, in Spanish populations, which fulfilled specific quality criteria and targeted prevalence of dementia in populations aged 70 years and above. Surveys covering 13 geographically different populations were selected (prevalence period: 1990-2008. Authors of original surveys provided methodological details of their studies through a systematic questionnaire and also raw age-specific data. Prevalence data were compared using direct adjustment and logistic regression. Results The reanalyzed study population (aged 70 year and above was composed of Central and North-Eastern Spanish sub-populations obtained from 9 surveys and totaled 12,232 persons and 1,194 cases of dementia (707 of Alzheimer's disease, 238 of vascular dementia. Results showed high variation in age- and sex-specific prevalence across studies. The reanalyzed prevalence of dementia was significantly higher in women; increased with age, particularly for Alzheimer's disease; and displayed a significant geographical variation among men. Prevalence was lowest in surveys reporting participation below 85%, studies referred to urban-mixed populations and populations diagnosed by psychiatrists. Conclusion Prevalence of dementia and Alzheimer's disease in Central and North-Eastern Spain is higher in females, increases with age, and displays considerable geographic variation that may be method-related. People suffering from dementia and Alzheimer's disease in Spain may approach 600,000 and 400,000 respectively. However, existing studies may not be completely appropriate to infer prevalence of dementia and its subtypes in Spain until surveys in Southern Spain are conducted.

    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.

    Background Delirium commonly occurs in patients with dementia. Though several tools for detecting delirium exist, it is unclear which are valid in patients with delirium superimposed on dementia. Objectives Identify valid tools to diagnose delirium superimposed on dementia Design We performed a systematic review of studies of delirium tools, which explicitly included patients with dementia. Setting In-hospital patients Participants Studies were included if delirium assessment tools were validated against standard criteria, and the presence of dementia was assessed according to standard criteria that used validated instruments. Measurements PubMed, Embase, and Web of Science databases were searched for articles in English published between January 1960 and January 2012. Results Nine studies fulfilled the selection criteria. Of the total of 1569 patients, 401 had dementia, and 50 had delirium superimposed on dementia. Six delirium tools were evaluated. One studyusing the Confusion Assessment Method (CAM) with 85% patients with dementia showed a high specificity (96–100%) and moderate sensitivity (77%).Two intensive care unit studies that used the CAM for the Intensive Care Unit (CAM-ICU) ICU reported 100% sensitivity and specificity for delirium among 23 dementia patients. One study using electroencephalography reported a sensitivity of 67% and a specificity of 91% among a population with 100% prevalence of dementia. No studies examined potential effects of dementia severity or subtype upon diagnostic accuracy. Conclusions The evidence base on tools for detection of delirium superimposed on dementia is limited, although some existing tools show promise. Further studies of existing or refined tools with larger samples and more detailed characterization of dementia are now required to address the identification of delirium superimposed on dementia.

Patients suffered on average from 4.5 (standard deviation ± 1.8) somatic diagnoses as well as 1.8 (standard deviation ± 0.5) psychiatric diagnoses. A diagnosis of dementia was ascertained according to ICD-10 criteria in 14%. Vascular dementia (66%) dominated over Alzheimer's dementia (23%) and other subtypes (11%).

    Full Text Available Dementia is a syndrome of progressive dysfunction of two or more cognitive domains associated with impairment of activities of daily living. An understanding of the pathophysiology of dementia and its early diagnosis is important in the pursuit of possible disease modifying therapy for dementia. Neuroimaging has greatly transformed this field of research as its function has changed from a mere tool for diagnosing treatable causes of dementia to an instrument for pre-symptomatic diagnosis of dementia. This review focuses on the diagnostic utility of neuroimaging in the management of progressive dementias. Structural imaging techniques like computerized tomography scan and magnetic resonance imaging highlights the anatomical, structural and volumetric details of the brain; while functional imaging techniques such as positron emission tomography, arterial spin labeling, single photon emission computerized tomography and blood oxygen level-dependent functional magnetic resonance imaging focuses on chemistry, circulatory status and physiology of the different brain structures and regions.

    Dementia is one of the main non-motor symptoms of Parkinson's disease (PD) and it is diagnosed in about 30% of cases. Its aetiology remains unclear and contributing factors are controversial. Dementia may be more common in old patients with severe motor symptoms and mild cognitive impairment. Clinico-pathological studies show the association between dementia in PD and the age-related group of dementias, such as AD and VaD. A valuable aid in the assessment of dementia in PD is cerebral blood flow (CBF) brain SPECT scanning. It shows three different patterns of rCBF reduction, including frontal lobe hypoperfusion, iu Alzheimer-likel type of hypoperfusion and multiple, vascular defects. The heterogeneity of rCBF reduction may reflect the multifactorial pathophysiology of dementia in PD. It may result from concomitant AD pathology, cerebrovascular disease, destruction of nigro-striato-frontal projection or may be a distinct disease of different aetiology. (author)

    2016-03-01

    The movement and music associated with dance plays an important role in many individuals' lives and can become imprinted upon the body and mind. Dance is thus closely associated with memory because of these deep connections. Without conscious thought, dance has the potential to be initiated as individuals age. In the current article, the authors share narrative reflections about their experiences with, and the potential of, dance as an intervention for aging populations diagnosed with dementia-related diseases. They draw upon their experiences in working with the aging population and a dance program currently being developed by Canada's National Ballet School and Baycrest Health Sciences for individuals with dementia-related diseases in long-term care. The current article is structured as dialogue between the authors because it mimics dance as a dialogical encounter between movement and music, and/or between individuals.

    To compare the prevalence of diagnosed depressive disorders, depressive symptoms and use of antidepressant medication between nursing home residents with and without dementia. This cross-sectional study used Minimal Data Set of the Resident Assessment Instrument 2.1 data collected in seven nursing homes located in an urbanized region in the Netherlands. Trained nurse assistants recorded all medical diagnoses made by a medical specialist, including dementia and depressive disorder, and medication use. Depressive symptoms were measured with the Depression Rating Scale. Multivariate logistic regression analysis was used to compare data between residents with and without dementia. Included in the study were 1885 nursing home residents (aged 65 years or older), of which 837 had dementia. There was no significant difference in the prevalence of diagnosed depressive disorder between residents with (9.6%) and without dementia (9.8%). Residents with dementia (46.4%) had more depressive symptoms than residents without dementia (22.6%). Among those with depressive symptoms, residents with dementia had the same likelihood of being diagnosed with a depressive disorder as residents without dementia. Among residents with a diagnosed depressive disorder, antidepressant use did not differ significantly between residents with dementia (58.8%) and without dementia (57.3%). The same holds true for residents with depressive symptoms, where antidepressant use was 25.3% in residents with dementia and 24.6% in residents without dementia. Regarding the prevalence rates of diagnosed depressive disorder and antidepressant use found in this study, our findings demonstrate that there is room for improvement not only for the detection of depression but also with regard to its treatment.

    Cerebral microbleeds are thought to represent cerebral amyloid angiopathy when in lobar regions of the brain and hypertensive arteriopathy when in deep and infratentorial locations. By studying cerebral microbleeds, their topography, and risk factors, we aimed to gain an insight into the vascular and amyloid pathology of dementia diagnoses and increase the understanding of cerebral microbleeds in dementia. We analyzed 1504 patients (53% women; mean age, 63 ± 10 years; 10 different dementia diagnoses) in this study. All patients underwent MR imaging as part of the dementia investigation, and all their clinical parameters were recorded. Among the 1504 patients with dementia, 22% had cerebral microbleeds. Cerebral microbleed topography was predominantly lobar (P = .01) and occipital (P = .007) in Alzheimer disease. Patients with cerebral microbleeds were significantly older (P < .001), were more frequently male (P < .001), had lower cognitive scores (P = .006), and more often had hypertension (P < .001). Risk factors for cerebral microbleeds varied depending on the dementia diagnosis. Odds ratios for having cerebral microbleeds increased with the number of risk factors (hypertension, hyperlipidemia, diabetes, male sex, and age 65 and older) in the whole patient group and increased differently in the separate dementia diagnoses. Prevalence, topography, and risk factors of cerebral microbleeds vary depending on the dementia diagnosis and reflect the inherent pathology of different dementia diagnoses. Because cerebral microbleeds are seen as possible predictors of intracerebral hemorrhage, their increasing prevalence with an increasing number of risk factors, as shown in our study, may require taking the number of risk factors into account when deciding on anticoagulant therapy in dementia. © 2015 by American Journal of Neuroradiology.

    : 200 picograms per milliliter or less is low, and 201 to 350 picograms per milliliter is borderline low. Other tests may be indicated, including plasma homocysteine, serum methylmalonic acid, antiparietal cell and anti-intrinsic factor antibodies, and serum gastrin level. In B12 deficiency dementia with versus without pernicious anemia, there appear to be different manifestations, need for further workup, and responses to treatment. Dementia of the Alzheimer’s type is a compatible diagnosis when B12 deficiency is found, unless it is caused by pernicious anemia. Patients with pernicious anemia generally respond favorably to supplemental B12 treatment, especially if pernicious anemia is diagnosed early in the course of the disease. Some patients without pernicious anemia, but with B12 deficiency and either mild cognitive impairment or mild to moderate dementia, might show some degree of cognitive improvement with supplemental B12 treatment. Evidence that supplemental B12 treatment is beneficial for patients without pernicious anemia, but with B12 deficiency and moderately-severe to severe dementia is scarce. Oral cyanocobalamin is generally favored over intramuscular cyanocobalamin.Keywords: Alzheimer, dementia, cognitive impairment, cognitive dysfunction, cobalamin, cyanocobalamin, B12, homocysteine, hyperhomocysteinemia, homocystinuria

    To examine whether imitation of gestures provided useful information to diagnose early dementia in elderly patients. Imitation of finger and hand gestures was evaluated in patients with mild dementia; 74 patients had dementia with Lewy bodies (DLB), 100 with Alzheimer's disease (AD) and 52 with subcortical vascular dementia (SVaD). Significantly, more patients with DLB (32.4%) compared with patients with AD (5%) or SVaD (11.5%) had an impaired ability to imitate finger gestures bilaterally. Also, significantly, more patients with DLB (36.5%) compared with patients with AD (5%) or SVaD (15.4%) had lower mean scores of both hands. In contrast, impairment of the imitation of bimanual gestures was comparable among the three patient groups (DLB 50%, AD 42%, SVaD 42.3%). Our study revealed that imitation of bimanual gestures was impaired non-specifically in about half of the patients with mild dementia, whereas imitation of finger gestures was significantly more impaired in patients with early DLB than in those with AD or SVaD. Although the sensitivity was not high, the imitation tasks may provide additional information for diagnosis of mild dementia, especially for DLB. Published by the BMJ Publishing Group Limited.

    Numerous studies have linked dementia to the subsequent deterioration of oral health. Few investigators, however, have examined oral disease as a potential risk factor in the development of dementia. The authors conducted a study to investigate a potential association between a history of oral disease and the development of dementia. Longitudinal dental records supplemented data collected from 10 annual cognitive assessments of 144 Milwaukee participants in the Nun Study, a longitudinal study of aging and Alzheimer disease, who were 75 to 98 years old. Neuropathologic findings at autopsy were available for 118 participants who died. A low number of teeth increased the risk of higher prevalence and incidence of dementia. Participants with the fewest teeth had the highest risk of prevalence and incidence of dementia. Edentulism or very few (one to nine) teeth may be predictors of dementia late in life.

    of a specific disease type such as Parkinson's disease or specific settings such as nursing homes. We extracted dementia study prevalence and dichotomised test positive/test negative results with thresholds used to diagnose dementia. This allowed calculation of sensitivity and specificity if not already reported in the study. Study authors were contacted where there was insufficient information to complete the 2x2 tables. We performed quality assessment according to the QUADAS-2 criteria.Methodological variation in selected studies precluded quantitative meta-analysis, therefore results from individual studies were presented with a narrative synthesis. Seven studies were selected: three in memory clinics, two in hospital clinics, none in primary care and two in population-derived samples. There were 9422 participants in total, but most of studies recruited only small samples, with only one having more than 350 participants. The prevalence of dementia was 22% to 54% in the clinic-based studies, and 5% to 10% in population samples. In the four studies that used the recommended threshold score of 26 or over indicating normal cognition, the MoCA had high sensitivity of 0.94 or more but low specificity of 0.60 or less. The overall quality and quantity of information is insufficient to make recommendations on the clinical utility of MoCA for detecting dementia in different settings. Further studies that do not recruit participants based on diagnoses already present (case-control design) but apply diagnostic tests and reference standards prospectively are required. Methodological clarity could be improved in subsequent DTA studies of MoCA by reporting findings using recommended guidelines (e.g. STARDdem). Thresholds lower than 26 are likely to be more useful for optimal diagnostic accuracy of MoCA in dementia, but this requires confirmation in further studies.

    MRI findings and risk factors for vascular dementia were evaluated with multi-variate analysis in 96 multi-infarct patients without dementia and 40 multi-infarct patients with dementia (MID). Only subjects with small infarcts in the territory of the perforator artery or deep white matter were studied. The diagnosis of MID was diagnosed according to DMS-III criteria and Hachinski's ischemia score. Location and area of patchy high-intensity areas including small infarcts, the degree of periventricular high intensity (PVH), and the degree of brain atrophy were examined with MR images. Independent variables were: history of hypertension, diabetes mellitus, other complications; systolic and diastolic blood pressure, atherosclerotic index, hematocrit, history of smoking, level of education, and activities of daily life (ADL). Hayashi's quantification method II was used to analyze the data. The most significant correlation was found between history of hypertension and dementia (partial correlation coefficient: 0.39). Significant correlations were also found between ADL and dementia (0.32), between thalamic infarction and dementia (0.31), and between PVH and dementia (0.27). Age, brain atrophy index, and history of diabetes mellitus contributed little to dementia. The contribution to dementia did not differ significantly between right and left patchy high-intensity areas on MR images. Location of infarcts, except for bilateral thalamic infarcts and large PVH, contributed little to dementia. Thus it would be difficult to base a prediction of the prevalence of vascular dementia on MRI findings. However, both hypertention and ADL contribute to vascular dementia and both are treatable, which may be significant for the prevention of dementia. (author)

    Despite guidelines stating the vaccine benefit in this population, older adults with dementia may be less likely to receive influenza vaccine than cognitively intact older adults. But no study has yet reported on vaccine uptake in patients newly diagnosed with dementia or whether years since dementia diagnosis influences vaccine uptake. We conducted a cohort study in the French Health Insurance database (Echantillon Généraliste de Bénéficiaires) which contains hospital data and claims for a 1/97th random sample of the French population. Diseased subjects were ≥65 years and had a new record of dementia diagnosis between September 1, 2007, and August 31, 2008. Vaccine receipt was measured via influenza vaccine dispensing in community pharmacies. We described influenza vaccination rates up to 2011-2012 and estimated adjusted relative risks (aRR) for vaccine receipt each year using multivariate modified Poisson models controlling for sociodemographics, comorbidities, and health resources use. Four hundred and seven subjects with dementia (mean age 81.8 years, 69.3% females) and 4862 subjects (mean age 75.2 years, 61.3% females) without dementia were included. In 2008-2009, influenza vaccination prevalence was 70.0% (95% CI = [65.3-74.4]) and 70.2% (95% CI = [68.9-71.4]) in subjects with and without dementia, respectively (aRR = 0.93; 95% CI = [0.87-1.00]). In 2009-2010, the aRR was of the same magnitude (aRR = 0.96, 95% CI = [0.90-1.03]), but in 2010-2011 and 2011-2012, the aRR was 1.02 (95% CI = [0.94-1.11]) and 1.05 (95% CI = [0.96-1.14]), respectively. Subjects with dementia had a slightly nonsignificant lower receipt of influenza vaccine in the year following dementia diagnosis than subjects without dementia. In subsequent years, divergent trends were observed in vaccine uptake according to dementia status. © 2017 Société Française de Pharmacologie et de Thérapeutique.

    Dementia is the leading cause of disability worldwide in the elderly individuals. Although prior studies have examined psychiatric symptoms in dementia caregivers, few studies have examined physician-diagnosed depression in the family caregiver of a patient with dementia. We used data from 457 864 respondents from the Korea Community Health Survey. We used logistic regression to examine the relationship between physician-diagnosed depression and cohabitation with a patient with dementia. Cohabitation with a patient with dementia (1.2% of the Korean population) was significantly associated with physician-diagnosed depression. The significance remained in females when the data were stratified by sex. A significant association also occurred among males with low family income. To reduce the burden of dementia, we need a management policy that includes the caregiver as well as the patient with dementia. In particular, political management for the vulnerable population, male caregiver in low-income family and female caregiver in high-income family, should be prepared. © The Author(s) 2016.

  9. The 10/66 Dementia Research Group's fully operationalised DSM-IV dementia computerized diagnostic algorithm, compared with the 10/66 dementia algorithm and a clinician diagnosis: a population validation study

    2008-06-01

    Full Text Available Abstract 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.

    Differential dementia diagnosis remains a challenge due to overlap of clinical profiles, which often results in diagnostic doubt. Determine the added diagnostic value of cerebrospinal fluid (CSF) biomarkers for differential dementia diagnosis as compared to autopsy-confirmed diagnosis. Seventy-one dementia patients with autopsy-confirmed diagnoses were included in this study. All neuropathological diagnoses were established according to standard neuropathological criteria and consisted of Alzheimer's disease (AD) or other dementias (NONAD). CSF levels of Aβ1 - 42, T-tau, and P-tau181 were determined and interpreted based on the IWG-2 and NIA-AA criteria, separately. A panel of three neurologists experienced with dementia made clinical consensus dementia diagnoses. Clinical and CSF biomarker diagnoses were compared to the autopsy-confirmed diagnoses. Forty-two patients (59%) had autopsy-confirmed AD, whereas 29 patients (41%) had autopsy-confirmed NONAD. Of the 24 patients with an ambiguous clinical dementia diagnosis, a correct diagnosis would have been established in 67% of the cases applying CSF biomarkers in the context of the IWG-2 or the NIA-AA criteria respectively. AD CSF biomarkers have an added diagnostic value in differential dementia diagnosis and can help establishing a correct dementia diagnosis in case of ambiguous clinical dementia diagnoses.

    To determine whether observed hearing loss (OHL) is associated with incident dementia in a multiethnic population. Prospective epidemiological cohort study. Community in northern Manhattan. Participants in the Washington Heights-Inwood Columbia Aging Project, a longitudinal study on aging and dementia in an ethnically diverse community (n = 1,881). OHL was defined when the examiner observed it or according to self-reported hearing aid use. A consensus panel diagnosed dementia using standard research criteria. A Cox proportional hazards model was used to examine the relationship between OHL at baseline and risk of incident dementia (mean 7.3 ± 4.4 years of longitudinal followup, range 0.9-20 years). OHL was associated with 1.69 (95% confidence interval (CI) = 1.3-2.3, P < .010) times the risk of incident dementia, adjusting for demographic characteristics, cardiovascular risk factors, apolipoprotein E4 genotype, and stroke. When stratified according to race, the association between OHL and incident dementia was high in all groups but was statistically significant only in blacks (hazard ratio = 2.62, 95% CI = 1.5-4.5, P < .010). OHL was associated with greater risk of incident dementia in a multiethnic cohort. More study is needed to determine whether HL contributes to dementia and whether treating HL can reduce the risk of dementia. © 2017, Copyright the Authors Journal compilation © 2017, The American Geriatrics Society.

  12. Which Stratum of Urban Elderly Is Most Vulnerable for Dementia?

    2016-01-01

    Many factors associated with a patient's lifestyle may disrupt timely access to dementia diagnosis and management. The aim of this study was to compare characteristics of lifestyle factors at the time of initial evaluation for dementia across degrees of dementia, and to identify risk factors relating to late detection of dementia, in order to understand the various lifestyle barriers to timely recognition of the disease. We reviewed medical records of 1,409 subjects who were diagnosed as dementia among 35,723 inhabitants of Gwangjin-gu. Dementia severity was divided into three degrees. Age, sex, education, income, smoking, heavy drinking, physical activity, religion, and living conditions were evaluated. There was a significantly greater proportion of individuals who were old age, female, less educated, who had never smoked or drank heavily, without physical activity, with no religious activity and living with family other than spouse in the severe dementia group. The lifestyle risks of late detection were old age, lower education, less social interactions, less physical activity or living with family. We can define this group of patients as the vulnerable stratum to dementia evaluation. Health policy or community health services might find ways to better engage patients in this vulnerable stratum to dementia. PMID:27550494

    2018-02-01

    The anticipated number of persons with dementia continues to grow, and the US has insufficiently planned to provide and pay for care for this large population. A number of significant clinical trials aiming to prevent or cure dementia, including Alzheimer's disease, have not demonstrated success. Because of the lack of efficacious treatments, and the fact that brain changes associated with dementia may begin decades before symptoms, we can predict that efforts to cure or prevent dementia will not succeed in time for millions of people in the baby boomer generation. Because of the anticipated increase in people suffering with dementia in the coming years, US health policy must address major gaps in how to provide and pay for dementia care. Reliance on Medicaid and Medicare as currently structured will not sustain the necessary care, nor can families alone provide all necessary dementia care. Innovative forms of providing long-term care and paying for it are crucially needed.

    To estimate the cost of dementia and the extra cost of caring for someone with dementia over the cost of caring for someone without dementia. We developed an evidence-based mathematical model to simulate disease progression for newly diagnosed individuals with dementia. Data-driven trajectories of cognition, function, and behavioral and psychological symptoms were used to model disease progression and predict costs. Using modeling, we evaluated lifetime and annual costs of individuals with dementia, compared costs of those with and without clinical features of dementia, and evaluated the effect of reducing functional decline or behavioral and psychological symptoms by 10% for 12 months (implemented when Mini-Mental State Examination score ≤21). Mathematical model. Representative simulated U.S. incident dementia cases. Value of informal care, out-of-pocket expenditures, Medicaid expenditures, and Medicare expenditures. From time of diagnosis (mean age 83), discounted total lifetime cost of care for a person with dementia was $321,780 (2015 dollars). Families incurred 70% of the total cost burden ($225,140), Medicaid accounted for 14% ($44,090), and Medicare accounted for 16% ($52,540). Costs for a person with dementia over a lifetime were $184,500 greater (86% incurred by families) than for someone without dementia. Total annual cost peaked at $89,000, and net cost peaked at $72,400. Reducing functional decline or behavioral and psychological symptoms by 10% resulted in $3,880 and $680 lower lifetime costs than natural disease progression. Dementia substantially increases lifetime costs of care. Long-lasting, effective interventions are needed to support families because they incur the most dementia cost. © 2017, Copyright the Authors Journal compilation © 2017, The American Geriatrics Society.

  15. Augmented Input Reveals Word Deafness in a Man with Frontotemporal Dementia

    Full Text Available We describe a 57 year old, right handed, English speaking man initially diagnosed with progressive aphasia. Language assessment revealed inconsistent performance in key areas. Expressive language was reduced to a few short, perseverative phrases. Speech was severely apraxic. Primary modes of communication included gesture, pointing, gaze, physical touch and leading. Responses were 100% accurate when he was provided with written words, with random or inaccurate responses for strictly auditory/verbal input. When instructions to subsequent neuropsychological tests were written instead of spoken, performance improved markedly. A comprehensive audiology assessment revealed no hearing impairment. Neuroimaging was unremarkable. Neurobehavioral evaluation utilizing written input led to diagnoses of word deafness and frontotemporal dementia, resulting in very different management. We highlight the need for alternative modes of language input for assessment and treatment of patients with language comprehension symptoms.

    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...

    This work investigates the possibility of predicting future onset of dementia in subjects who are cognitively normal, using hippocampal shape and volume information extracted from MRI scans. A group of 47 subjects who were non-demented normal at the time of the MRI acquisition, but were diagnosed...... with dementia during a 9 year follow-up period, was selected from a large population based cohort study. 47 Age and gender matched subjects who stayed cognitively intact were selected from the same cohort study as a control group. The hippocampi were automatically segmented and all segmentations were inspected...... and, if necessary, manually corrected by a trained observer. From this data a statistical model of hippocampal shape was constructed, using an entropy-based particle system. This shape model provided the input for a Support Vector Machine classifier to predict dementia. Cross validation experiments...

    Similarities in presentation of Dementia of Alzheimer's Type, Vascular Dementia, Frontotemporal Dementia, and Major Depressive Disorder, pose differential diagnosis challenges. The current study identifies specific neuropsychological patterns of scores for Dementia of Alzheimer's Type, Vascular Dementia, Frontotemporal Dementia, and Major Depressive Disorder. Neuropsychological domains directly assessed in the study included: immediate memory, delayed memory, confrontational naming, verbal fluency, attention, concentration, and executive functioning. The results reveal specific neuropsychological comparative profiles for Dementia of Alzheimer's Type, Vascular Dementia, Frontotemporal Dementia, and Major Depressive Disorder. The identification of these profiles will assist in the differential diagnosis of these disorders and aid in patient treatment.

    Poor gait performance predicts risk of developing dementia. No structured critical evaluation has been conducted to study this association yet. The aim of this meta-analysis was to systematically examine the association of poor gait performance with incidence of dementia. An English and French Medline search was conducted in June 2015, with no limit of date, using the medical subject headings terms "Gait" OR "Gait Disorders, Neurologic" OR "Gait Apraxia" OR "Gait Ataxia" AND "Dementia" OR "Frontotemporal Dementia" OR "Dementia, Multi-Infarct" OR "Dementia, Vascular" OR "Alzheimer Disease" OR "Lewy Body Disease" OR "Frontotemporal Dementia With Motor Neuron Disease" (Supplementary Concept). Poor gait performance was defined by standardized tests of walking, and dementia was diagnosed according to international consensus criteria. Four etiologies of dementia were identified: any dementia, Alzheimer disease (AD), vascular dementia (VaD), and non-AD (ie, pooling VaD, mixed dementias, and other dementias). Fixed effects meta-analyses were performed on the estimates in order to generate summary values. Of the 796 identified abstracts, 12 (1.5%) were included in this systematic review and meta-analysis. Poor gait performance predicted dementia [pooled hazard ratio (HR) combined with relative risk and odds ratio = 1.53 with P analysis provides evidence that poor gait performance predicts dementia. This association depends on the type of dementia; poor gait performance is a stronger predictor of non-AD dementias than AD.

    Full text: This presentation will focus on the role of MRI in the diagnosis of dementia and related diseases. We will discuss the following subjects: 1. Systematic assessment of MR in dementia 2. MR protocol for dementia 3. Typical findings in the most common dementia syndrome Alzheimer's disease (AD), Vascular Dementia (VaD), Frontotemporal lobe dementia (FTLD) 4. Short overview of neurodegenerative disorders which may be associated with dementia. The role of neuroimaging in dementia nowadays extends to support the diagnosis of specific neurodegenerative disorders. It is a challenge to the early diagnosis of neurodegenerative diseases such as Alzheimer's disease. Early diagnosis includes recognition of predementia conditions, such as mild cognitive impairment (MCI). Neuroimaging may also be used to assess disease progression and is adopted in current trials investigating MCI and AD. An MR-study of a patient suspected of having dementia must be assessed in a standardized way. First of all, treatable diseases like subdural hematomas, tumors and hydrocephalus need to be excluded. Next we should look for signs of specific dementias such as: Alzheimer's disease (AD): medial temporal lobe atrophy (MTA) and parietal atrophy. Frontotemporal Lobar Degeneration (FTLD): (asymmetric) frontal lobe atrophy and atrophy of the temporal pole. Vascular Dementia (VaD): global atrophy, diffuse white matter lesions, lacunas and 'strategic infarcts' (infarcts in regions that are involved in cognitive function). Dementia with Lewy bodies (DLB): in contrast to other forms of dementia usually no specific abnormalities. So when we study the MR images we should score in a systematic way for global atrophy, focal atrophy and for vascular disease (i.e. infarcts, white matter lesions, lacunas)

    Full Text Available Background The AD8 plays an important role in the early diagnosis of dementia. However, because of cultural and language difference, it is difficult for Chinese subjects to understand and answer questions in AD8. This paper aims to make a new dementia self-rating questionnaire for Chinese people based on the AD8, and to determine its value for dementia screening.  Methods According to early symptoms of dementia and life style of old Chinese people, a dementia self-rating questionnaire was made based on the AD8. The new questionnaire includes 10 questions, and can be finished in 3 min. The reliability and validity was validated by a questionnaire survey in senior citizens older than 50 years in urban Xi'an. All patients were screened by Mini-Mental State Examination (MMSE and dementia was diagnosed according to Diagnostic and Statistical Manual of Mental Disorders Forth Edition (DSM-Ⅳ criteria.  Results A total of 620 patients finished the new questionnaire, and among them 17 patients (2.74% were diagnosed as dementia. The score of each question in the questionnaire was positively correlated with the total score (rs = 0.300-0.709; P = 0.000, for all. The Cronbach α was 0.795, indicating that the questionnaire got good internal consistency reliability. Two principal components were extracted, and the cumulative variance contribution ratio was 49.771%. Factor loading of each subitem was > 0.500, indicating a good construct validity. According to receiver operating characteristic (ROC curve, the critical value was 2, with the sensitivity 94.10% and specificity 82.10%. Youden index was 0.762.  Conclusions The new dementia self-rating questionnaire can detect dementia patients sensitively and correctly, and is very useful for early screening of dementia. DOI: 10.3969/j.issn.1672-6731.2015.07.009

  5. Depression associated with dementia.

    2015-06-01

    Depression and cognitive disorders, including dementia and mild cognitive impairment, are common disorders in old age. Depression is frequent in dementia, causing distress, reducing the quality of life, exacerbating cognitive and functional impairment and increasing caregiver stress. Even mild levels of depression can significantly add to the functional impairment of dementia patients and the severity of psychopathological and neurological impairments increases with increasing severity of depression. Depressive symptoms may be both a risk factor for, as well as a prodrome of dementia. Major depressive syndrome of Alzheimer's disease may be among the most common mood disorders of older adults. Treating depression is therefore a key clinical priority to improve the quality of life both of people with dementia as well as their carergivers. Nonpharmacological approaches and watchful waiting should be attempted first in patients who present with mild to moderate depression and dementia. In cases of severe depression or depression not able to be managed through nonpharmacological means, antidepressant therapy should be considered.

    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)

    Dementia is the major public health problem among the elderly in developed countries and a growing problem in the underdeveloped countries. There are no published data on dementia in any of the Arab countries. The aim of this study was to determine the different subtypes of dementia among Qataris. A retrospective and prospective ongoing hospital based study in which all medical records of the patients with diagnosis of dementia seen at the Hamad General Hospital, Doha, Qatar, between June 1997 and June 2003, whether inpatient and outpatient were reviewed. Dementia was defined according to diagnostic and statistical manual (DSM) IV criteria. Those who had dementia were evaluated by a psychologist, psychiatrist, neurologist and a geriatrician. All had brain computerized tomography, magnetic resonance imaging or both and routine blood test. Finally, they were classified into sub-types according to the cause of dementia. One of 300 patients, 134 fulfilled the inclusion criteria, most of them were illiterate, married and non-smokers. Among those dementia sub-types were: Alzheimer disease (AD) 39 (29%), vascular dementia (VaD) 30 (22%), mixed AD and VaD 20 (15%) and Parkinson's disease with dementia due to other medical conditions. Our stidy showed that AD is more prevalent than VaD. It also showed that patients and their families seek medical help late due to to the general belief among the public that forgetfulness and other associated cognitive impairment are part of normal aging process. The emergence of new drugs and advancement in prevention of cerebrovascular diseases make early diagnosis of dementia sub-type important. A community based study to show the real prevalence and incidence of sub-types of dementia is highly indicated. These data are necessory for planning and setting up community services and health care programs for demented patients. (author)

    The historical events in the evolution of Alzheimer's disease are reviewed, including the initial description by Alois Alzheimer and the subsequent controversy regarding the nosological specificity of this entity. The similarity of senile dementia and Alzheimer's disease is emphasized. The basis for the modern concept of Alzheimer's disease as premature or accelerated aging is included in the review. The pathological correlates of the major categories of adult dementia have been described. The traditional criteria of neurofibrillary tangles and senile plaques have been re-evaluated using the current insight into these changes afforded by electron microscopy and biochemistry. The significance of amyloid has been described because it occurs within the senile plaque and also as the essential component of congophilic angiopathy. The new information regarding neuronal cell counts and the loss of choline acetyltransferase has been evaluated in terms of an indication of a pathogenic mechanism of Alzheimer's disease. The current understanding of normal pressure hydrocephalus, Creutzfeldt-Jakob disease, and multi-infarct dementia has been described. Brain biopsy in dementia has been described as having diagnostic, research, pathogenic, and prognostic value. The precautions involving the performance and handling of the biopsy have been stressed, particularly because these procedures involve conditions of possible slow virus etiology. The polemic for Alzheimer's disease as aging or slow virus infection has been summarized. At this time a consideration seems justified that Alzheimer's disease is an age-related, slow virus disease due to a hitherto unknown immune defect. Aging as an etiological agent must be clarified before Alzheimer's disease, in any form, can be considered to be an inevitable consequence of longevity.

    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.

    The causes of death in dementia are not established, particularly in rarer dementias. The aim of this study is to calculate risk of death from specific causes for a broader spectrum of dementia diagnoses. Cohort study. Swedish Dementia Registry (SveDem), 2007-2012. Individuals with incident dementia registered in SveDem (N = 28,609); median follow-up 741 days. Observed deaths were 5,368 (19%). Information on number of deaths and causes of mortality was obtained from death certificates. Odds ratios for the presence of dementia on death certificates were calculated. Hazard ratios (HRs) and 95% confidence intervals (CIs) were calculated using Cox hazards regression for cause-specific mortality, using Alzheimer's dementia (AD) as reference. Hazard ratios for death for each specific cause of death were compared with hazard ratios of death from all causes (P-values from t-tests). The most frequent underlying cause of death in this cohort was cardiovascular (37%), followed by dementia (30%). Dementia and cardiovascular causes appeared as main or contributory causes on 63% of certificates, followed by respiratory (26%). Dementia was mentioned less in vascular dementia (VaD; 57%). Compared to AD, cardiovascular mortality was higher in individuals with VaD than in those with AD (HR = 1.82, 95% CI = 1.64-2.02). Respiratory death was higher in individuals with Lewy body dementia (LBD, including Parkinson's disease dementia and dementia with Lewy bodies, HR = 2.16, 95% CI = 1.71-2.71), and the risk of respiratory death was higher than expected from the risk for all-cause mortality. Participants with frontotemporal dementia were more likely to die from external causes of death than those with AD (HR = 2.86, 95% CI = 1.53-5.32). Dementia is underreported on death certificates as main and contributory causes. Individuals with LBD had a higher risk of respiratory death than those with AD. © 2016 The Authors.

    Clinical applications of PET studies for dementia are reviewed in this paper. At the mild and moderate stages of Alzheimer's disease (AD), glucose metabolism is reduced not only in the parietotemporal region but also in the posterior cingulate and precuneus. At the advanced stage of AD, there is also a metabolic reduction in the frontal region. In AD patients, glucose metabolism is relatively preserved in the pons, sensorimotor cortices, primary visual cortices, basal ganglia, thalamus and cerebellum. In patients with dementia with Lewy bodies, glucose metabolism in the primary visual cortices is reduced, and this reduction appears to be associated with the reduction pattern in AD patients. In patients with frontotemporal dementia, reduced metabolism in the frontotemporal region is the main feature of this disease, but reduced metabolism in the basal ganglia, and/or parietal metabolic reduction can be associated with the frontotemporal reduction. When corticobasal degeneration is associated with dementia, the reduction pattern of dementia is similar to the reduction pattern in AD and the hallmarks of diagnosing corticobasal degeneration associated with dementia are a reduced metabolism in the primary sensorimotor region and/or basal ganglia and an asymmetric reduction in the two hemispheres. FDG-PET is a very useful tool for the diagnosis of early AD and for the differential diagnosis of dementia. I also describe clinical applications of PET for the diagnosis of dementia in Japan.

    This study aimed to determine the prevalence of dementia in collaboration with urban/regional Aboriginal communities. A census of Aboriginal and Torres Strait Islander men and women aged 60 years and above in the target communities identified 546 potential participants, with 336 (61.5%) participating in this cross-sectional study. Participants completed a structured interview and cognitive screening tests. One hundred fifty-three participants also completed a detailed medical assessment. Assessment data were reviewed by a panel of clinicians who determined a diagnosis of dementia or mild cognitive impairment (MCI) according to standard criteria. Crude prevalence of dementia was 13.4%, and age-standardized prevalence was 21.0%. The most common types of dementia were Alzheimer's dementia (44%) and mixed dementia diagnoses (29%). Estimated prevalence of MCI was 17.7%. Consistent with previous findings in a remote population, urban and regional Aboriginal Australians face high rates of dementia at younger ages, most commonly Alzheimer's dementia.

  16. The Interface of Delirium and Dementia in Older Persons

    Delirium and dementia are two of the most common causes of cognitive impairment in older populations, yet their interrelationship remains poorly understood. Previous studies have documented that dementia is the leading risk factor for delirium; and delirium is an independent risk factor for subsequent dementia. However, a major area of controversy is whether delirium is simply a marker of vulnerability to dementia, whether the impact of delirium is solely related to its precipitating factors, or whether delirium itself can cause permanent neuronal damage and lead to dementia. Ultimately, it is likely that all of these hypotheses are true. Emerging evidence from epidemiological, clinicopathological, neuroimaging, biomarker, and experimental studies provide support for a strong interrelationship and for both shared and distinct pathological mechanisms. Targeting delirium for new preventive and therapeutic approaches may offer the sought-after opportunity for early intervention, preservation of cognitive reserve, and prevention of irreversible cognitive decline in ageing.

    To identify distinct behavioral patterns of diet, exercise, social interaction, church attendance, alcohol consumption, and smoking and to examine their association with subsequent dementia risk. Longitudinal, population-based dementia study. Rural county in northern Utah, at-home evaluations. Two thousand four hundred ninety-one participants without dementia (51% male, average age 73.0 ± 5,7; average education 13.7 ± 4.1 years) initially reported no problems in activities of daily living and no stroke or head injury within the past 5 years. Six dichotomized lifestyle behaviors were examined (diet: high ≥ median on the Dietary Approaches to Stop Hypertension scale; exercise: ≥5 h/wk of light activity and at least occasional moderate to vigorous activity; church attendance: attending church services at least weekly; social Interaction: spending time with family and friends at least twice weekly; alcohol: currently drinking alcoholic beverages ≥ 2 times/wk; nonsmoker: no current use or fewer than 100 cigarettes ever). Latent class analysis (LCA) was used to identify patterns among these behaviors. Proportional hazards regression modeled time to dementia onset as a function of behavioral class, age, sex, education, and apolipoprotein E status. Follow-up averaged 6.3 ± 5.3 years, during which 278 cases of incident dementia (200 Alzheimer's disease (AD)) were diagnosed. LCA identified four distinct lifestyle classes. Unhealthy-religious (UH-R; 11.5%), unhealthy-nonreligious (UH-NR; 10.5%), healthy-moderately religious (H-MR; 38.5%), and healthy-very religious (H-VR; 39.5%). UH-NR (hazard ratio (HR) = 0.54, P = .028), H-MR (HR = 0.56, P = .003), and H-VR (HR = 0.58, P = .005) had significantly lower dementia risk than UH-R. Results were comparable for AD, except that UH-NR was less definitive. Functionally independent older adults appear to cluster into subpopulations with distinct patterns of lifestyle behaviors with different levels of risk for subsequent

    Sporadic Creutzfeldt-Jakob disease is a rare neurodegenerative disorder of unknown etiology that causes rapidly progressive dementia. This disease is uniformly fatal and most patients die within 12 months. Clinical findings include myoclonus, visual disturbances, and cerebellar and pyramidal/extrapyramidal signs in addition to rapidly progressive cognitive and functional impairment. These findings are all non-specific and it is often difficult and challenging to diagnose premortem because of low awareness and clinical suspicion. We present a 66-year-old woman with a 5-month history of rapidly progressive dementia. After a series of extensive diagnostic examinations and continuous follow-up, she was diagnosed with probable sporadic Creutzfeldt-Jakob disease based on Centers for Disease Control and Prevention (CDC) criteria, with key findings of rapidly progressive dementia, blurry vision, extrapyramidal signs (cogwheel rigidity), and abnormal hyperintensity signals on diffusion-weighted MRI. Her symptoms progressively worsened and she died 7 months after the onset. The postmortem brain autopsy demonstrated the presence of abnormal protease-resistant prion protein by Western Blot analysis. A literature review was performed on differential diagnoses that present with rapidly progressive dementia and thereby mimic sporadic Creutzfeldt-Jakob disease. These include Alzheimer's disease, dementia with Lewy Bodies, frontotemporal dementia, meningoencephalitis, corticobasal degeneration, progressive supranuclear palsy, CADASIL, and paraneoplastic encephalomyelitis.

    Introduction In early stages of Alzheimer’s dementia, some patients are still fit to drive, but others are not (Ernst et al., 2010). Therefore, fitness to drive should be evaluated when people have been diagnosed with dementia. The gold standard to determine fitness to drive is an on-road assessment

    Improving dementia care is a policy priority nationally and internationally; there is a 'diagnosis gap' with less than half of the cases of dementia ever diagnosed. The English Health Department's Quality and Outcomes Framework (QOF) encourages primary care recognition and recording of dementia. The codes for dementia are complex with the possibility of underidentification through miscoding. We developed guidance on coding of dementia; we report the impact of applying this to 'clean up' dementia coding and records at a practice level. The guidance had five elements: (1) identify Read Codes for dementia; (2) access QOF dementia register; (3) generate lists of patients who may have dementia; (4) compare search with QOF data and (5) review cases. In each practice, one general practitioner conducted the exercise. The number of dementia QOF registers before and after the exercise was recorded with the hours taken to complete the exercise. London primary care. 23 (85%) of 27 practices participated, covering 79 312 (19 562 over 65 s) participants. The number on dementia QOF registers; time taken. The number of people with dementia on QOF registers increased from 1007 to 1139 (χ(2)=8.17, p=0.004), raising identification rates by 8.8%. It took 4.7 h per practice, on an average. These data demonstrate the potential of a simple primary care coding exercise, requiring no specific training, to increase the dementia identification rate. An improvement of 8.8% between 2011 and 2012 is equivalent to that of the fourth most improved primary care trust in the UK. In absolute terms, if this effects were mirrored across the UK primary care, the number of cases with dementia identified would rise by over 70 000 from 364 329 to 434 488 raising the recognition rate from 46% to 54.8%. Implementing this exercise appears to be a simple and effective way to improve recognition rates in primary care.

    Electroconvulsive therapy (ECT) is the most effective treatment for severe episodes of mood disorders. Temporary memory loss is a common side-effect, but ongoing discussions exist regarding potential long-term adverse cognitive outcomes. Only a few studies have examined the frequency of dementia in patients after ECT. The aim of this study was to examine the association between ECT and risk of subsequent dementia in patients with a first-time hospital diagnosis of affective disorder. We did a cohort study of patients aged 10 years and older in Denmark with a first-time hospital contact for an affective disorder from Jan 1, 2005, through Dec 31, 2015, identified in the Danish National Patient Registry with ICD-10 codes F30.0 to F39.9. From the registry we retrieved information on all ECTs registered for patients and followed up patients for incidental dementia (defined by hospital discharge diagnoses or acetylcholinesterase inhibitor use) until Oct 31, 2016. We examined the association between ECT and dementia using Cox regression analyses with multiple adjustments and propensity-score matching on sociodemographic and clinical variables. Of 168 015 patients included in the study, 5901 (3·5%) patients had at least one ECT. During the median follow-up of 4·9 years (IQR 2·4-7·8) and 872 874 person years, the number of patients who developed dementia was 111 (0·1%) of 99 045 patients aged 10-49 years, 965 (2·7%) of 35 945 aged 50-69 years, and 4128 (12·5%) of 33 025 aged 70-108 years. 217 (3·6%) of the 5901 patients treated with ECT developed dementia, whereas of 162 114 patients not treated with ECT 4987 (3·1%) developed dementia. The corresponding incidences were 70·4 cases per 10 000 person-years (95% CI 61·6-80·5) and 59·2 per 10 000 person-years (57·6-60·8). In patients younger than 50 years and 50-69 years, ECT was not associated with a risk of dementia compared with age-matched patients who were not given ECT (age-adjusted hazard

    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. © 2015 Elsevier B.V.

    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.

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

    2013-01-01

    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.

  11. Early dementia diagnosis and the risk of suicide and euthanasia.

    2010-01-01

    Diagnosis of dementia is occurring earlier, and much research concerns the identification of predementia states and the hunt for biomarkers of Alzheimer's disease. Reports of suicidal behavior and requests for euthanasia in persons with dementia may be increasing. We performed a selective literature review of suicide risk in persons with dementia and the ethical issues associated with euthanasia in this population. In the absence of any effective treatments for Alzheimer's disease or other types of dementia, there is already evidence that persons with mild cognitive change and early dementia are at risk of suicidal behavior, often in the context of comorbid depression. The ensuing clinical, ethical, and legal dilemmas associated with physician-assisted suicide and euthanasia in the context of dementia are a subject of intense debate. By analogy, the preclinical and early diagnoses of Huntington's disease are associated with an increased risk of suicidal behavior. Thus there is the potential for a preclinical and early diagnosis of Alzheimer's disease (through biomarkers, neuroimaging, and clinical assessment) to result in increased suicide risk and requests for physician-assisted suicide. Although dementia specialists have long recognized the importance of a sensitive approach to conveying bad news to patients and families and the possibility of depressive reactions, suicidal behavior has not been regarded as a likely outcome. Such preconceptions will need to change, and protocols to monitor and manage suicide risk will need to be developed for this population. 2010 The Alzheimer's Association. Published by Elsevier Inc.

    Nursing theory, research, and best practice guidelines contribute substantially to the field of dementia care. Interventional plans are challenged most by those dementias considered progressive and deteriorative in nature, requiring ongoing reassessment and modification of care practices as the clinical course changes. The purpose of this article is to provide guidelines for case managers in the development of effective, individualized care plans for clients with progressive dementia residing in a home setting. The application of these guidelines is illustrated through the presentation of an actual case. The practice setting is a private home in the Pacific Northwest. Geriatric case management is provided by an RN case manager. Progressive dementia presents challenges to home care. Professional case management using comprehensive, holistic assessment, collaborative approaches, and best practice fundamentals serve to create an effective, individualized plan of care. The increasing geriatric population presents great opportunities for case managers in strategic management for creating successful home care models in clients with progressive dementia. Use of nursing diagnoses, dementia research, and collaborative approaches with families and other medical providers creates a viable alternative for clients with progressive dementia.

    Brain perfusion SPECT is a functional and noninvasive neuroimaging technique that allow the investigation of physiological and physiopathologic events in the human brain, including cerebral perfusion and function. Interventional rCBF imaging can also evaluate cerebrovascular reserve. In clinically, rCBF imaging play an important role in the diagnosis and differential diagnosis of dementias, especially vascular and Alzheimer's dementia. If etiology of some types of dementias is determined so that it can be early diagnosed, treated and taken prevention; the partial patients with dementia can get recovery or remission

    Differentiation of delirium and dementia is a key diagnostic challenge but there has been limited study of features that distinguish these conditions. We examined neuropsychiatric and neuropsychological symptoms in elderly medical inpatients to identify features that distinguish major neurocognitive disorders. University teaching hospital in Ireland. 176 consecutive elderly medical inpatients (mean age 80.6 ± 7.0 years (range 60-96); 85 males (48%)) referred to a psychiatry for later life consultation-liaison service with Diagnostic and Statistical Manual of Mental Disorders (DSM) IV delirium, dementia, comorbid delirium-dementia and cognitively intact controls. Participants were assessed cross-sectionally with comparison of scores (including individual items) for the Revised Delirium Rating Scale (DRS-R98), Cognitive Test for Delirium (CTD) and Neuropsychiatric Inventory (NPI-Q). The frequency of neurocognitive diagnoses was delirium (n=50), dementia (n=32), comorbid delirium-dementia (n=62) and cognitively intact patients (n=32). Both delirium and comorbid delirium-dementia groups scored higher than the dementia group for DRS-R98 and CTD total scores, but all three neurocognitively impaired groups scored similarly in respect of total NPI-Q scores. For individual DRS-R98 items, delirium groups were distinguished from dementia groups by a range of non-cognitive symptoms, but only for impaired attention of the cognitive items. For the CTD, attention (p=0.002) and vigilance (p=0.01) distinguished between delirium and dementia. No individual CTD item distinguished between comorbid delirium-dementia and delirium. For the NPI-Q, there were no differences between the three neurocognitively impaired groups for any individual item severity. The neurocognitive profile of delirium is similar with or without comorbid dementia and differs from dementia without delirium. Simple tests of attention and vigilance can help to distinguish between delirium and other presentations

    We compared the proportion of ischemic heart disease (IHD) patients newly diagnosed with dementia and depression across three treatment groups: percutaneous coronary intervention (PCI), coronary artery bypass grafting (CABG) and medical management alone (IHD-medical). De-identified, individual-level administrative records of health service use for the population of Manitoba, Canada (approximately 1.1 million) were examined. From April 1, 1993 to March 31, 1998, patients were identified with a diagnosis of IHD (ICD-9-CM codes). Index events of CABG or PCI were identified from April 1, 1998 to March 31, 2003. Outcomes were depression or dementia after the index event. Patients were followed forward to March 31, 2006 or until censored. Proportional hazards regression analysis was undertaken. Independent variables examined were age, sex, diabetes, hypertension and income quintile, medical management alone for IHD, or intervention by PCI or CABG. Age, sex, diabetes, and presence of hypertension were all strongly associated with the diagnosis of depression and dementia. There was no association with income quintile. Dementia was less frequent with PCI compared to medical management; (HR = 0.65; p = 0.017). CABG did not provide the same protective effect compared to medical management (HR = 0.90; p = 0.372). New diagnosis depression was more frequent with interventional approaches: PCI (n = 626; hazard ratio = 1.25; p = 0.028) and CABG (n = 1124, HR = 1.32; p = 0.0001) than non-interventional patients (n = 34,508). Subsequent CABG was nearly 16-fold higher (pdementia-only 65% of the risk for medical management alone. Both interventional approaches were associated with a higher risk of new diagnosed depression compared to medical management. Long-term myocardial revascularization was superior with CABG. These findings suggest that PCI may confer a long-term protective effect from dementia. The mechanism(s) of dementia protection

    With an ageing population, the number of people with dementia is rising. The economic impact on the health care system is considerable and new treatment methods and approaches to dementia care must be cost effective. Economic evaluation requires valid patient reported outcome measures, and this study aims to develop a dementia-specific health state classification system based on the Quality of Life for Alzheimer's disease (QOL-AD) instrument (nursing home version). This classification system will subsequently be valued to generate a preference-based measure for use in the economic evaluation of interventions for people with dementia. We assessed the dimensionality of the QOL-AD to develop a new classification system. This was done using exploratory and confirmatory factor analysis and further assessment of the structure of the measure to ensure coverage of the key areas of quality of life. Secondly, we used Rasch analysis to test the psychometric performance of the items, and select item(s) to describe each dimension. This was done on 13 items of the QOL-AD (excluding two general health items) using a sample of 284 residents living in long-term care facilities in Australia who had a diagnosis of dementia. A five dimension classification system is proposed resulting from the three factor structure (defined as 'interpersonal environment', 'physical health' and 'self-functioning') derived from the factor analysis and two factors ('memory' and 'mood') from the accompanying review. For the first three dimensions, Rasch analysis selected three questions of the QOL-AD ('living situation', 'physical health', and 'do fun things') with memory and mood questions representing their own dimensions. The resulting classification system (AD-5D) includes many of the health-related quality of life dimensions considered important to people with dementia, including mood, global function and skill in daily living. The development of the AD-5D classification system is an important step

    A connection between dementias and blood-brain barrier (BBB) dysfunction has been suggested, but previous studies have yielded conflicting results. We examined cerebrospinal fluid (CSF)/serum albumin ratio in a large cohort of patients diagnosed with Alzheimer's disease (AD, early onset [EAD, n = 130], late onset AD [LAD, n = 666]), vascular dementia (VaD, n = 255), mixed AD and VaD (MIX, n = 362), Lewy body dementia (DLB, n = 50), frontotemporal dementia (FTD, n = 56), Parkinson's disease dementia (PDD, n = 23), other dementias (other, n = 48), and dementia not otherwise specified (NOS, n = 271). We compared CSF/serum albumin ratio to 2 healthy control groups (n = 292, n = 20), between dementia diagnoses, and tested biomarker associations. Patients in DLB, LAD, VaD, MIX, other, and NOS groups had higher CSF/serum albumin ratio than controls. CSF/serum albumin ratio correlated with CSF neurofilament light in LAD, MIX, VaD, and other groups but not with AD biomarkers. Our data show that BBB leakage is common in dementias. The lack of association between CSF/serum albumin ratio and AD biomarkers suggests that BBB dysfunction is not inherent to AD but might represent concomitant cerebrovascular pathology.

    Delirium occurring in patients with dementia is referred to as delirium superimposed on dementia (DSD). People who are older with dementia and who are institutionalized are at increased risk of developing delirium when hospitalized. In addition, their prior cognitive impairment makes detecting their delirium a challenge. The Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition and the International Statistical Classification of Diseases and Related Health Problems, 10th Revision are considered the standard reference for the diagnosis of delirium and include criteria of impairments in cognitive processes such as attention, additional cognitive disturbances, or altered level of arousal. The Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition and the International Statistical Classification of Diseases and Related Health Problems, 10th Revision does not provide guidance regarding specific tests for assessment of the cognitive process impaired in delirium. Importantly, the assessment or inclusion of preexisting cognitive impairment is also not addressed by these standards. The challenge of DSD gets more complex as types of dementia, particularly dementia with Lewy bodies, which has features of both delirium and dementia, are considered. The objective of this article is to critically review key elements for the diagnosis of DSD, including the challenge of neuropsychological assessment in patients with dementia and the influence of particular tests used to diagnose DSD. To address the challenges of DSD diagnosis, we present a framework for guiding the focus of future research efforts to develop a reliable reference standard to diagnose DSD. A key feature of a reliable reference standard will improve the ability to clinically diagnose DSD in facility-based patients and research studies. PMID:27650668

In addition, we searched Google Scholar and OpenSIGLE for grey literature. We intended to review randomised controlled trials (RCTs) and clustered randomised trials with blinded assessment of outcomes that evaluated an electronic assistive device used with the single aim of supporting memory function in people diagnosed with dementia. The control interventions could either be 'care (or treatment) as usual' or non-technological psychosocial interventions (including interventions that use non-electronic assistive devices) also specifically aimed at supporting memory. Outcome measures included activities of daily living, level of dependency, clinical and care-related outcomes (for example admission to long-term care), perceived quality of life and well-being, and adverse events resulting from the use of AT; as well as the effects of AT on carers. Two review authors independently screened all titles and abstracts identified by the search. We identified no studies which met the inclusion criteria. This review highlights the current lack of high-quality evidence to determine

    Full Text Available In the absence of biological markers, dementia classification remains complex both in terms of characterization as well as early detection of the presence or absence of dementing symptoms, particularly in diseases with possible secondary dementia. An empirical, statistical approach using neuropsychological measures was therefore developed to distinguish demented from non-demented patients and to identify differential patterns of cognitive dysfunction in neurodegenerative disease. Age-scaled neurobehavioral test results (Wechsler Adult Intelligence Scale—Revised and Wechsler Memory Scale from Alzheimer's (AD and Huntington's (HD patients, matched for intellectual disability, as well as normal controls were used to derive a classification formula. Stepwise discriminant analysis accurately (99% correct distinguished controls from demented patients, and separated the two patient groups (79% correct. Variables discriminating between HD and AD patient groups consisted of complex psychomotor tasks, visuospatial function, attention and memory. The reliability of the classification formula was demonstrated with a new, independent sample of AD and HD patients which yielded virtually identical results (classification accuracy for dementia: 96%; AD versus HD: 78%. To validate the formula, the discriminant function was applied to Parkinson's (PD patients, 38% of whom were classified as demented. The validity of the classification was demonstrated by significant PD subgroup differences on measures of dementia not included in the discriminant function. Moreover, a majority of demented PD patients (65% were classified as having an HD-like pattern of cognitive deficits, in line with previous reports of the subcortical nature of PD dementia. This approach may thus be useful in classifying presence or absence of dementia and in discriminating between dementia subtypes in cases of secondary or coincidental dementia.

METHODS: Two hundred...... patients were randomly selected from 891 patients aged ≤65 years registered with a diagnosis of dementia for the first time in 2008 in Danish hospitals, and 159 medical records were available for review. Three raters evaluated their medical records for the completeness of the diagnostic work-up on which...... the diagnosis of dementia had been based, using evidence-based guidelines for the diagnostic evaluation of dementia as reference standards. RESULTS: According to the rater review, only 111 (70%) patients met the clinical criteria for dementia. An acceptable diagnostic work-up including all items of recommended...

  7. Early Dementia Screening

    2016-01-01

    Full Text Available As the population of the world increases, there will be larger numbers of people with dementia and an emerging need for prompt diagnosis and treatment. Early dementia screening is the process by which a patient who might be in the prodromal phases of a dementing illness is determined as having, or not having, the hallmarks of a neurodegenerative condition. The concepts of mild cognitive impairment, or mild neurocognitive disorder, are useful in analyzing the patient in the prodromal phase of a dementing disease; however, the transformation to dementia may be as low as 10% per annum. The search for early dementia requires a comprehensive clinical evaluation, cognitive assessment, determination of functional status, corroborative history and imaging (including MRI, FDG-PET and maybe amyloid PET, cerebrospinal fluid (CSF examination assaying Aβ1–42, T-τ and P-τ might also be helpful. Primary care physicians are fundamental in the screening process and are vital in initiating specialist investigation and treatment. Early dementia screening is especially important in an age where there is a search for disease modifying therapies, where there is mounting evidence that treatment, if given early, might influence the natural history—hence the need for cost-effective screening measures for early dementia.

    As the aging of the world's population is becoming increasingly serious, dementia-related diseases have become a hot topic in public health research. In recent years, human epidemiological studies have focused on lipid metabolism disorders and dementia. The efficacy of phytosterol intake as a cholesterol-lowering agent has been demonstrated. Phytosterols directly serve as ligands of the nuclear receptors, peroxisome proliferator-activated receptors (PPARs), activating Sirtuin 1 (SIRT-1), which are involved in the regulation of lipid metabolism and the pathogenesis of dementia. Moreover, phytosterols mediate cell and membrane cholesterol efflux or beta amyloid (Aβ) metabolism, which have preventative and therapeutic effects on dementia. Additionally, incorporation of plant sterols in lipid rafts can effectively reduce dietary fat and alter the dietary composition of fiber, fat and cholesterol to regulate appetite and calories. Overall, the objectives of this review are to explore whether phytosterols are a potentially effective target for the prevention of dementia and to discuss a possible molecular mechanism by which phytosterols play a role in the pathogenesis of dementia via the PPARs-SIRT-1 pathway.

    Sexuality in later life and its relationship to dementia is a neglected topic: greater understanding of the area has the potential to contribute to the quality of life of people with dementia, their family members, and formal carers. We review current knowledge about sexuality, aging, and dementia. We undertook a review of the recent literature to examine of the following areas: what is known about sexuality and aging, and about attitudes to sexuality and aging; what is known about the relevance of sexuality and aging to people living with dementia and their care; and the management of sexual behaviors causing concern to others. Sexual activity decreases in frequency with increasing age but many older people remain sexually active; there is no age limit to sexual responsiveness; and sexuality is becoming more important to successive cohorts of older people, including people living with dementia and gay, lesbian, bisexual, and transgendered elderly people. Attitudes and beliefs toward sexuality and aging are strongly influenced by stereotypes and myths, not only among the general public but also among those working in health and social care. Professional bodies should include sexuality, aging, and dementia in their training curricula. More work is needed on the impact of environmental issues, particularly in group living situations, on older adults' sexuality, and on consent issues. Ethical decision-making frameworks can be useful in practice. Organizations should investigate how to support staff in avoiding a problem-orientated approach and focus on providing holistic person-centered care.

    It seems to be very complicated even for the experienced neurologist and psychiatrist to correlate the clinical syndrome of dementia to different causing cerebral processes such as a primarily degenerative brain atrophy, a chronic cerebrovascular insufficiency, or other rarer occurring brain diseases unless neurological signs and symptoms do indicate a focal brain lesion. Since computed tomography is able to show both focal and general changes of the brain tissue each patient presenting with a dementia clinically should be undergone such a neuroradiological investigation at least once, and if being negative even repeatedly. Computed tomography is able not only to detect unexpected treatable brain lesions as a cause of dementia for instance tumors, subdural hematomas, and communicating hydrocephalus to expect in about 6% of cases with the clinical diagnosis of dementia, but also it is able to help to make the differentialdiagnosis of the dementia of Alzheimer's and the multi-infarct-type in a high percentage. Nevertheless despite the use of computed tomography the pathogenesis of dementia even though being undoubtful clinically remains obscure in 15% of our material of 367 demented patients studied by computed tomography but presenting with a normal finding.

    Full Text Available Introduction The number of patients suffering from diabetes mellitus is growing globally. It is expected to observe 253.4 million sufferers in geriatric population in 2045. In this time, also 131.5 million of people is going to have dementia and other cognitive problems. In people aged over 65 these two diseases are concomitant quite often. What are the connections in the area of etiology and treatment? Aim The purpose of this study is to present links between dementia and diabetes are depicted in professional literature. Results Diabetes and dementia are associated on many levels. These conditions have common risk factors. Diabetes may contribute to cognitive impairment in many ways, promoting development of atherosclerosis, brain vessel damage and vascular dementia. Alzheimer disease may be promoted by hyperglycemia and hyperinsulinemia. On contrary also hypoglycaemia, often met in elderly diabetic patients has negative impact on cognitive function. Dementia seriously affects treatment of diabetes. The main problems are not satisfying adherence and diabetes self-management. Conclusions Prevention of diabetes and dementia risk factors can be performed simultaneously as the are common for both diseases. Enhancing physical activity, reducing saturated fats consumption, levels of cholesterol and body mass are considered to be beneficial in the context of described conditions. Furthermore, treatment of diabetes is strongly affected by cognitive dysfunction. Management of dementive diabetics requires individualization and using long-acting drugs. It is crucial to reduce risk of life-threatening hypoglycaemias and to create wide team to take care of these patients.

  12. A clinical study on the usefulness of CT and MRI imaging in evaluating differential diagnosis and the degree of dementia in vascular dementia

    In a retrospective review of 117 computed tomography (CT) scans and 56 magnetic resonance imaging (MRI) scans sequentially performed for dementia patients, CT and MRI were compared for assessment of the usefulness in the differential diagnosis and determination of the functional prognosis of vascular dementia. The correlation between CT findings and the degree of mental function was also examined. Since MRI had a higher sensitivity than CT in detecting small infarcts or lacunaes in the perforating area or white matter, it should differentiate vascular dementia from dementia of Alzheimer type. When both dementia of Alzheimer type was clinically diagnosed and infarct areas were detected on either CT or MRI, activity of daily living tended to be poor. Even when mixed type of dementia or vascular dementia was clinically diagnosed in spite of negative findings on either CT or MRI, troublesome behavior was frequently observed, posing the likelihood of dementia of Alzheimer type. The ability of CT and MRI to detect lesions was not correlated with the degree of dementia or aging, even if MRI was capable of detecting smaller lesions. CT was thus considered to be more specific modality for evaluating mental function. The size of lesions on CT was found to be more significant than the number and localization of lesions in determining the degree of dementia in the chronic stage of cerebrovascular disease. The ability of MRI to detect smaller lesions, as well as clinically determined ischemic scores, may assist in the diagnostic differentiation. Lesion size on CT may be an important factor for determining the degree of dementia and functional prognosis. (N.K.).

    Evidence suggests that education protects from dementia by enhancing cognitive reserve. However, this may be influenced by several socio-demographic factors. Rising numbers of dementia in India, high levels of illiteracy and heterogeneity in socio-demographic factors provide an opportunity to explore this relationship. To study the association between education and age at dementia onset, in relation to socio-demographic factors. Association between age at dementia onset and literacy was studied in relationship to potential confounding factors such as gender, bilingualism, place of dwelling, occupation, vascular risk factors, stroke, family history of dementia and dementia subtypes. Case records of 648 dementia patients diagnosed in a specialist clinic in a University hospital in Hyderabad, India were examined. All patients were prospectively enrolled as part of an ongoing longitudinal project that aims to evaluate dementia subjects with detailed clinical, etiological, imaging, and follow-up studies. Of the 648 patients, 98 (15.1%) were illiterate. More than half of illiterate skilled workers were engaged in crafts and skilled agriculture unlike literates who were in trade or clerical jobs. Mean age at onset in illiterates was 60.1 years and in literates 64.5 years (p=0.0002). Factors independently associated with age at dementia onset were bilingualism, rural dwelling and stroke, but not education. Our study demonstrates that in India, rural dwelling, bilingualism, stroke and occupation modify the relationship between education and dementia.

    2013-04-01

    Many minority ethnic (ME) older adults face several culturally associated and systemic barriers to timely dementia diagnoses that may result in delays to dementia care-seeking. We aimed to develop and propose a model illustrating variables that influence dementia care-seeking among ME older adults. We conducted a literature review on the effects of these barriers on diagnostic delays and impairment levels at initial evaluation. We also strived to provide a basis for the Sociocultural Health Belief Model (SHBM) to guide future research and service planning pertaining to culture and dementia care-seeking. There was consistent evidence that ME older adults with dementia tended to have greater diagnostic delays and higher levels of cognitive impairment and behavioral and psychological symptoms of dementia at initial evaluation than their non-Hispanic White counterparts. We also found several barriers to dementia care-seeking among ME groups. These barriers included lower levels of acculturation and accurate knowledge about dementia, more culturally associated beliefs about dementia, such as the perception of memory loss as normal aging and stigma associated with dementia, and health system barriers. The SHBM provides an empirically based conceptual framework for examining cross-cultural differences in dementia care-seeking among diverse groups. We provide recommendations for future research, such as the need for research with more diverse ethnic subgroups and the examination of group-specific cultural values. We conclude with a discussion of the clinical and service implications of our review, including potential interventions aimed at facilitating timely dementia diagnoses among ME older adults.

    Full Text Available This review aims to evaluate the existing evidence for pharmacotherapy for management of dementia. Data search strategies included electronic databases of relevant publications or cross-references. The searches were limited to acetyl cholinesterase inhibitors (AChEIs, memantine, antipsychotics, antidepressants, mood stabilizers, and benzodiazepines. Data in the form of meta-analysis and systemic reviews for treatment in five main types of dementia (Alzheimer′s, frontotemporal, Parkinson′s, Lewy body disease, and vascular type were extracted. If a meta-analysis or systemic review was not available, then the searches included evaluation of data in the form of double-blind, randomized controlled trials or open-label studies. Various studies suggest that compared to placebo, AChEIs and memantine are associated with better outcome in all domains of Alzheimer′s disease. In addition, combination therapy of AChEIs and memantine is superior to monotherapy with AChEIs in terms of behavioral disturbances, activities of daily living, and global assessment. In patients with dementia associated with Parkinson′s disease or Lewy body dementia, use of donepezil, rivastigmine, and memantine is associated with significant efficacy on the global outcome measures when compared with placebo. Compared to placebo, AChEIs, but not memantine, have also been shown to have better cognitive outcomes in patients with dementia associated with Parkinson′s disease or Lewy body dementia. Data are limited for the role of pharmacotherapy in management of frontotemporal dementia. In patients of vascular dementia, all AChEIs and memantine show some beneficial effects on cognition. Antidepressants and antipsychotics have been shown to be beneficial in management of behavioral symptoms and agitation. However, it is important to remember that there is black box warning for use of antipsychotics among patients with dementia. One of the major limitations of the research is

    We performed an observational study of laughter during seminaturalistic conversations between patients with dementia and familial caregivers. Patients were diagnosed with (1) behavioural variant frontotemporal dementia (bvFTD), (2) right temporal variant frontotemporal dementia (rtFTD), (3) semantic variant of primary progressive aphasia (svPPA), (4) non-fluent variant primary progressive aphasia (nfvPPA) or (5) early onset Alzheimer's disease (eoAD). We hypothesised that those with bvFTD would laugh less in response to their own speech than other dementia groups or controls, while those with rtFTD would laugh less regardless of who was speaking. Patients with bvFTD (n=39), svPPA (n=19), rtFTD (n=14), nfvPPA (n=16), eoAD (n=17) and healthy controls (n=156) were recorded (video and audio) while discussing a problem in their relationship with a healthy control companion. Using the audio track only, laughs were identified by trained coders and then further classed by an automated algorithm as occurring during or shortly after the participant's own vocalisation ('self' context) or during or shortly after the partner's vocalisation ('partner' context). Individuals with bvFTD, eoAD or rtFTD laughed less across both contexts of self and partner than the other groups. Those with bvFTD laughed less relative to their own speech comparedwith healthy controls. Those with nfvPPA laughed more in the partner context compared with healthy controls. Laughter in response to one's own vocalisations or those of a conversational partner may be a clinically useful measure in dementia diagnosis. © Article author(s) (or their employer(s) unless otherwise stated in the text of the article) 2017.

    2008-04-01

    Full Text Available Abstract Background Early diagnosis of dementia benefits both patient and caregiver. Nevertheless, dementia in primary care is currently under-diagnosed. Some educational interventions developed to improve dementia diagnosis and management were successful in increasing the number of dementia diagnoses and in changing attitudes and knowledge of health care staff. However, none of these interventions focussed on collaboration between GPs and nurses in dementia care. We developed an EASYcare-based Dementia Training Program (DTP aimed at stimulating collaboration in dementia primary care. We expect this program to increase the number of cognitive assessments and dementia diagnoses and to improve attitudes and knowledge of GPs and nurses. Methods The DTP is a complex educational intervention that consists of two workshops, a coaching program, access to an internet forum, and a Computerized Clinical Decision Support System on dementia diagnostics. One hundred duos of GPs and nurses will be recruited, from which 2/3 will be allocated to the intervention group and 1/3 to the control group. The effects of implementation of the DTP will be studied in a cluster-randomised controlled trial. Primary outcomes will be the number of cognitive assessments and dementia diagnoses in a period of 9 months following workshop participation. Secondary outcomes are measured on GP and nurse level: adherence to national guidelines for dementia, attitude, confidence and knowledge regarding dementia diagnosis and management; on patient level: number of emergency calls, visits and consultations and patient satisfaction; and on caregiver level: informal caregiver burden and satisfaction. Data will be collected from GPs' electronic medical records, self-registration forms and questionnaires. Statistical analysis will be performed using the MANOVA-method. Also, exploratory analyses will be performed, in order to gain insight into barriers and facilitators for implementation and

    Driving constitutes a very important aspect of daily life and is dependent on cognitive functions such as attention, visuo-spatial skills and memory, which are often compromised in dementia. Therefore, the driving fitness of patients with dementia needs to be addressed by physicians and those that are deemed unfit should not be allowed to continue driving. We aimed at investigating to what extent physicians assess driving fitness in dementia patients and determinant factors for revoking of their licenses. This study includes 15113 patients with newly diagnosed dementia and driver's license registered in the Swedish Dementia Registry (SveDem). The main outcomes were reporting to the licensing authority and making an agreement about driving eligibility with the patients. Physicians had not taken any action in 16% of dementia patients, whereas 9% were reported to the authority to have their licenses revoked. Males (OR = 3.04), those with an MMSE score between 20-24 (OR = 1.35) and 10-19 (OR = 1.50), patients with frontotemporal (OR = 3.09) and vascular dementia (OR = 1.26) were more likely to be reported to the authority. For the majority of patients with dementia, driving fitness was assessed. Nevertheless, physicians did not address the issue in a sizeable proportion of dementia patients. Type of dementia, cognitive status, age, sex and burden of comorbidities are independent factors associated with the assessment of driving fitness in patients with dementia. Increased knowledge on how these factors relate to road safety may pave the way for more specific guidelines addressing the issue of driving in patients with dementia.

    This paper presents a literature review whose aim was to provide better understanding of living with early-stage dementia. Even in the early stages, dementia may challenge quality of life. Research on early-stage dementia is mainly in the domain of biomedical aetiology and pathology, providing little understanding of what it means to live with dementia. Knowledge of the lived experience of having dementia is important in order to focus pro-active care towards enhancing quality of life. Qualitative research is fundamentally well suited to obtaining an insider's view of living with early-stage dementia. We performed a meta-synthesis of qualitative research findings. We searched MEDLINE, CINAHL, and PsycINFO and reviewed the papers cited in the references of pertinent articles, the references cited in a recently published book on the subjective experience of dementia, one thesis, and the journal Dementia. Thirty-three pertinent articles were identified, representing 28 separate studies and 21 different research samples. Findings were coded, grouped, compared and integrated. Living with dementia is described from the stage a person discovers the memory impairment, through the stage of being diagnosed with dementia, to that of the person's attempts to integrate the impairment into everyday life. Memory loss often threatens perceptions of security, autonomy and being a meaningful member of society. At early stages of memory loss, individuals use self-protecting and self-adjusting strategies to deal with perceived changes and threats. However, the memory impairment itself may make it difficult for an individual to deal with these changes, thereby causing frustration, uncertainty and fear. Our analysis supports the integration of proactive care into the diagnostic process, because even early-stage dementia may challenge quality of life. Moreover, this care should actively involve both the individual with dementia and their family so that both parties can adjust positively

    Many studies have sought to determine the predictors of institutionalization of patients with dementia. Such studies, performed in developed western societies, have come to various conclusions which may not be supported in an East Asian culture such as that found in Korea. This study aimed to determine the factors that predict institutionalization of patients in Korea diagnosed with dementia. Seventy-nine cases (37 institutionalized, 42 community-dwelling) in the Kwangju area were evaluated for patient characteristics, severity of dementia symptoms, caregiver characteristics, burden and distress. Logistic regression was performed to determine predictors of actual institutionalization. Six predictors of institutionalization were identified. Of these, three were patient-related factors: higher score on the Clinical Dementia Rating, higher score on the Brief Psychiatric Rating Scale, and shorter duration of dementia. The other three were caregiver-related factors: younger age, higher education (formal schooling), and higher cost of home care. As seen in previous western studies, institutionalization of dementia sufferers was influenced by both patient and caregiver factors. But, the specific predictors and their relative influences might be explained best by the particular social, cultural and economic situation in Korea. This study was the first of its kind in Korea and, as such, could serve as a reference for future intra-cultural and cross-cultural comparisons. Copyright 2002 John Wiley & Sons, Ltd.

    The potential of early interventions for dementia has increased interest in cognitive impairments less severe than dementia. However, predictors of the trajectory from intact cognition to dementia have not yet been clearly identified. The purpose of this study was to determine whether known risk factors for dementia increased the risk of mild cognitive impairments or progression from mild cognitive impairments to dementia. A polytomous logistic regression model was used, with parameters governing transitions within transient states (intact cognition, mild cognitive impairments, global impairment) estimated separately from parameters governing the transition from transient to absorbing state (dementia or death). Analyses were based on seven annual examinations (1991-2002) of 470 Nun Study participants aged > or = 75 years at baseline and living in the United States. Odds of developing dementia increased with age primarily for those with low educational levels. In these women, presence of an apolipoprotein E gene *E4 allele increased the odds more than fourfold by age 95 years. Age, education, and the apolipoprotein E gene were all significantly associated with mild cognitive impairments. Only age, however, was associated with progression to dementia. Thus, risk factors for dementia may operate primarily by predisposing individuals to develop mild cognitive impairments; subsequent progression to dementia then depends on only time and competing mortality.

    There are few longitudinal studies of dementia in developing countries. We used longitudinal data from the Maracaibo Aging Study to accurately determine the age- and sex-specific incidence of dementia in elderly Latin Americans. The Diagnostic and Statistical Manual of Mental Disorders (Fourth Edition, Text Revision) was used to diagnose dementia, which was classified as Alzheimer's disease, vascular dementia, or other. Age- and sex-specific incidence was estimated as the number of new cases of dementia divided by person-years (p-y) of follow-up. The incidence of all dementia diagnoses was 9.10 per 1000 p-y (95% confidence interval [CI] 7.13-11.44; 8026 total p-y), 5.18 for Alzheimer's disease (95% CI 3.72-7.03; 7916 total p-y), and 3.35 for vascular dementia (95% CI 2.19-4.91; 7757 total p-y). Among Maracaibo Aging Study participants younger than 65 years, the incidence of dementia was higher than that of US Whites. Among individuals older than 65 years, the incidence was comparable to the mean of previous incidence estimates for other populations worldwide. Copyright © 2017 the Alzheimer's Association.

    Objective: To evaluate the effects of long-term low dose and low dose-rate ionizing radiation exposure on the prevalence rate of senile dementia, further assess the effects of low-dose radiation exposure on central nervous system and study the pathogen of senile dementia, and provide direct observational data of human beings. Methods: A cross-sectional study of the prevalence of senile dementia was carried out in high background radiation areas in Yangjiang, Guangdong Province, China. The survey was conducted in two stages. For the initial screening, Hasegawa Dementia Scale (HDS) was used for all subjects. In the second stage, the stage of diagnosis, special questionnaires of healthy state of old people were sued. The final diagnoses were made according to the third revised edition of the Diagnostic and Statistical Manual of Mental Disorders (DSM III-R) of American Psychiatric Association. Results: 1018 inhabitants aged 65 years and over, including 513 persons in HBRA and 505 in CA were observed. According to DSM III-R, 61 cases (31 cases in HBRA and 30 cases in CA) of senile dementia were diagnosed. The prevalence rates of senile dementia are 6.04% in HBRA and 5.94% in CA, the total prevalence rate being 5.99%. Conclusion: No significant statistical difference in the prevalence rate of senile dementia between the two areas was found, suggesting that the prevalence rate of senile dementia in these areas is not associated with the high background radiation exposure

    Artistic creativity can be defined as the ability to produce both innovative and esthetic works. Though most dementias result in a loss of instrumental functions and a deterioration in artistic production, for some established artists, dementia, most often Alzheimer's disease, changed their style and technique but preserved their creativity and prolific artistic drive. Moreover, in some cases, mainly frontotemporal dementia, Parkinson's disease, and very occasionally strokes, the disease may favour the emergence of de novo artistic talent. This phenomenon has been conceptualized as a paradoxical facilitation, a disinhibition of brain areas devoted to visuospatial processing, greater freedom in a patient who becomes less bound by social conventions, enhancement of motivation and pleasure, etc. These neurological cases provide an opportunity to shed some light on the roots of artistic creation.

    Full Text Available Background: Most patients with dementia lose body weight over the course of the disease and have a lower body mass index (BMI than subjects with normal cognition. Aims: To examine body mass index and how it correlates with cognitive status, age and gender in patients with different dementia disorders. Materials and Methods: Data from newly diagnosed dementia patients in the Swedish Dementia Quality Registry (SveDem and recorded information about age, gender, cognitive status and BMI was analyzed using independent samples t tests and one-way analysis of variance. Results: A total of 12,015 patients, 7,121 females and 4,894 males were included in the study. The average BMI was 24. More than a quarter of the patients had a BMI of Conclusion: At the time of diagnosis, patients with various dementia disorders had a BMI within the normal range. However, a significant number had a BMI in a lower, suboptimal range for older persons stressing the need for nutritional assessment as part of the dementia work up. Further analyses with longitudinal follow-up are needed to investigate BMI changes over time.

    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).

  3. Dementia and sculpture-making: Exploring artistic responses of people with dementia.

    In its form, sculpture reveals not only the artist's self-expression but also the transformative qualities through which it influences our senses. Frequent interactions with sculpture can provide creative awareness, which in turn leads to a better understanding and appreciation of artistic expressions. This paper examines possible ways in which the creative potential of people with dementia can be explored through meaningful artistic engagement with sculpture-making processes. A study was conducted involving seven participants diagnosed with the early stages of dementia who engaged and experimented with different types of sculpture-making processes, from clay and papier mâché to virtual and digital sculptures. In the collective and collaborative environment of the group sessions, the creative responses of the participants to each process were unique. Each sculpture created by the participants enfolded their self-initiated ideas and stories reflecting the conscious expressions of their presence in a particular time and space. This paper argues that while cognitive impairment may affect the behavioural, visual and perceptual abilities of people with dementia, there is ample evidence to suggest that the viewing and making sculpture may influence the sensory involvement and consequently the imagination and creativity of people with early stage dementia.

    Low life satisfaction predicts adverse outcomes, and may predict dementia. The objectives were: (1) to determine if life satisfaction predicts dementia over a five year period in those with normal cognition at baseline; and (2) to determine if different aspects of life satisfaction differentially predict dementia. Secondary analysis of an existing population-based cohort study with initial assessment in 1991 and follow-up five years later. Initially, 1,751 adults age 65+ living in the community were sampled from a representative sampling frame. Of these, 1,024 were alive and had complete data at time 2, of whom 96 were diagnosed with dementia. Life satisfaction was measured using the Terrible-Delightful scale, which measures overall life satisfaction on a 7-point scale, as well as various aspects of life satisfaction (e.g. friendships, finances, etc.) Dementia was diagnosed by clinical examination using DSM-IIIR criteria. Logistic regression models were constructed for the outcome of dementia at time 2, and adjusted for age, gender, education, and comorbidities. Overall life satisfaction predicted dementia five years later, at time 2. The unadjusted Odds Ratio (OR; 95% confidence interval) for dementia at time 2 was 0.72 (0.55, 0.95) per point. The adjusted OR for dementia was 0.70 (0.51, 0.96). No individual item on the life satisfaction scale predicted dementia. However, the competing risk of mortality was very high for some items. A global single-item measure of life satisfaction predicts dementia over a five year period in older adults without cognitive impairment.

    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

    To determine the prevalence of dementia in Thai people with age 45 years and above. This project used a cross sectional research design to study the prevalence of dementia in Chiang Mai. Door-to-door technique was assigned in condition with multi-stage probability random sampling to obtain subjects representing the population of Chiang Mai between Oct 2004 and Sep 2005. The researchers collected the data from the subjects aged 45 years and above. All subjects were located from every Amphurs of Chiang Mai. They were first screened with Thai Mini Mental State Examination (TMSE) and Thai Beck Depression Inventory (BDI). The subjects whose TMSE was less than 24 were assessed and diagnosed by a neurologist. Subjects who were determined as having dementia might be laboratory analyzed and classified based on DSM-IV and NINDS-AIREN criteria. The authors enrolled 2,311 people and screened them with Batteries test. One thousand four hundred ninety two people qualified with 610 males and 882 females, whose mean age was 59.7 +/- 10.4 years. The authors found that among the 35 people with dementia, the mean age was 67.9 +/- 8.9 years (45-88 years). The prevalence of dementia among the study participants was 2.35%. In the present study, Alzheimer's disease was the most common type of dementia diagnosed (75.0%) and vascular dementia was the second most commonly diagnosed (12.5%). The prevalence of dementia in Chiang Mai was 2.35%, which does not differ from the previous study Alzheimer's disease was the most common type of dementia diagnosed.

    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. © The Author(s) 2016.

    In the context of the demographically induced increase in the prevalence of dementia and the simultaneous lack of causal pharmacological therapies, preventive approaches are gaining in importance. By reducing risk factors and with measures which induce neuroplasticity successful aging can be supported. This article summarizes the current developments in preventing dementia by modification of life style factors. The main focus lies on the impact of cognitive and physical activity on neuroprotection. A promising approach combines both activities within a dance training program. Further studies that meet the demanding criteria of a randomized clinical trial are urgently needed.

    2003-10-01

    Memantine (Ebixa--Lundbeck Ltd), an oral medicine, is available in the UK for treating "patients with moderately severe to severe Alzheimer's disease". It differs from other licensed dementia medicines in that it is an N-methyl-D-aspartate (NMDA) receptor antagonist. The company has claimed that, with memantine therapy, "improvements in activities of daily living help patients to maintain a degree of independence and be easier to care for, potentially avoiding the need for nursing home care". We assess the efficacy of memantine for dementia and discuss its place in the management of patients with Alzheimer's disease.

    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.

    Electronic linkage of UK cohorts to routinely collected National Health Service (NHS) records provides virtually complete follow-up for cause-specific hospital admissions and deaths. The reliability of dementia diagnoses recorded in NHS hospital data is not well documented. For a sample of Million Women Study participants in England we compared dementia recorded in routinely collected NHS hospital data (Hospital Episode Statistics: HES) with dementia recorded in two separate sources of primary care information: a primary care database [Clinical Practice Research Datalink (CPRD), n = 340] and a survey of study participants' General Practitioners (GPs, n = 244). Dementia recorded in HES fully agreed both with CPRD and with GP survey data for 85% of women; it did not agree for 1 and 4%, respectively. Agreement was uncertain for the remaining 14 and 11%, respectively; and among those classified as having uncertain agreement in CPRD, non-specific terms compatible with dementia, such as 'memory loss', were recorded in the CPRD database for 79% of the women. Agreement was significantly better (p primary care (CPRD) than in hospital (HES) data. Age-specific rates for dementia based on the hospital admission data were lower than the rates based on the primary care data, but were similar if the delay in recording in HES was taken into account. Dementia recorded in routinely collected NHS hospital admission data for women in England agrees well with primary care records of dementia assessed separately from two different sources, and is sufficiently reliable for epidemiological research.

    1989-01-01

    In order to evaluate the relationship between the regional cerebral blood flow (CBF) and cerebrovascular dementia, eleven patients with vascular dementia and eight patients with non-demented infarction were studied and regional CBF were measured quantitatively with single photon emission computed tomography (SPECT) by using N-isopropyl-p-(I-123) iodoamphetamine. All cases were basal infarction and vascular dementia were diagnosed by less than 21.5 of the Hasegawa's dementia score and more than 7 of Hachinsk's ischemic score. The results of the present study were as follows: (1) Cerebrovascular dementia showed lower mean CBF value compared with non-demented group. (2) Regional CBF of bilateral frontal areas and affected basal ganglia were significantly reduced than occipital area in the dementia group. (3) A comparison of regional CBF and the Hasegawa's dementia score revealed a statistically significant correlation at the bilateral frontal areas in the dementia group. It is possible that measuring the regional CBF quantitatively by IMP-SPECT is useful for clinical analysis of vascular dementia. (author)

    The purpose of the study was to determine the association between bilingualism and age at onset of dementia and its subtypes, taking into account potential confounding factors. Case records of 648 patients with dementia (391 of them bilingual) diagnosed in a specialist clinic were reviewed. The age at onset of first symptoms was compared between monolingual and bilingual groups. The influence of number of languages spoken, education, occupation, and other potentially interacting variables was examined. Overall, bilingual patients developed dementia 4.5 years later than the monolingual ones. A significant difference in age at onset was found across Alzheimer disease dementia as well as frontotemporal dementia and vascular dementia, and was also observed in illiterate patients. There was no additional benefit to speaking more than 2 languages. The bilingual effect on age at dementia onset was shown independently of other potential confounding factors such as education, sex, occupation, and urban vs rural dwelling of subjects. This is the largest study so far documenting a delayed onset of dementia in bilingual patients and the first one to show it separately in different dementia subtypes. It is the first study reporting a bilingual advantage in those who are illiterate, suggesting that education is not a sufficient explanation for the observed difference. The findings are interpreted in the context of the bilingual advantages in attention and executive functions.

    Complementary therapy has received great interest within the field of dementia treatment and the use of aromatherapy and essential oils is increasing. In a growing population where the majority of patients are treated by US Food and Drug Administration (FDA)-approved drugs, the efficacy of treatment is short term and accompanied by negative side effects. Utilisation of complimentary therapies in dementia care settings presents as one of few options that are attractive to practitioners and families as patients often have reduced insight and ability to verbally communicate adverse reactions. Amongst the most distressing features of dementia are the behavioural and psychological symptoms. Addressing this facet has received particular interest in aromatherapy trials, with a shift in focus from reducing cognitive dysfunction to the reduction of behavioural and psychological symptoms in dementia. To assess the efficacy of aromatherapy as an intervention for people with dementia. ALOIS, the Cochrane Dementia and Cognitive Improvement Group Specialized Register, was searched on 26 November 2012 and 20 January 2013 using the terms: aromatherapy, lemon, lavender, rose, aroma, alternative therapies, complementary therapies, essential oils. All relevant randomised controlled trials were considered. A minimum length of a trial and requirements for follow-up were not included, and participants in included studies had a diagnosis of dementia of any type and severity. The review considered all trials using fragrance from plants defined as aromatherapy as an intervention with people with dementia and all relevant outcomes were considered. Titles and abstracts extracted by the searches were screened for their eligibility for potential inclusion in the review. For Burns 2011, continuous outcomes were estimated as the mean difference between groups and its 95% confidence interval using a fixed-effect model. For Ballard 2002, analysis of co-variance was used for all outcomes, with the

    Dementia associated with hyperthyroidism is less well documented than is hypothyroid dementia. Therapeutic response of hyperthyroid dementia and associated cerebral circulatory and/or metabolic abnormalities has not been elucidated. We described a patient with hyperthyroid dementia and clinicoradiological response to treatment. Single photon emission computed tomographic (SPECT) study was repeated and analyzed semiquantitatively. A 67-year-old man experienced progressive impairments of attention, memory, constructive skills and behavior as well as hand tremor and weight loss of two-year duration. Laboratory findings were compatible with Graves' disease. The initial SPECT showed diffuse tracer uptake defect with an accentuation in the bilateral temporoparietal regions. Clinical and SPECT findings both suggested concurrent "possible" Alzheimer's disease. However, initial treatment with a beta-blocker improved behavior and attention-related cognitive functions as well as tracer uptake in the frontal lobes. Subsequent treatment with additional methimazole then improved memory and constructive abilities when a euthyroid state was established. Uptake defect in the temporoparietal regions also responded gradually to the medication. We suggest that the present patient represent hyperthyroid dementia, which responds favorably to treatment with regard to clinical symptoms and SPECT findings. We also suggest that thyroid function be measured in patients with "possible" Alzheimer's disease because treatable hyperthyroid dementia may not be identified.

    Mild cognitive impairment (MCI) refers to the transitional state between the normal elderly and dementia. This concept accelerated many clinical, epidemiological and neuroimaging research in recent 10 years about an early stage of dementia. These studies have approved a significance of this concept and MCI have been classified into subtypes, including prodromal forms of a variety of dementias. An algorithm is proposed to assist the clinician in subclassifying subjects into the various types of MCI, but new several concepts, such as vascular cognitive impairment, still confused clinicians. Therefore, definition and diagnostic procedure for MCI were discussed in this review. Several population-based studies as well as Alzheimer's Disease Neuroimaging Initiative (ADNI) study have documented a higher rate of progression to Alzheimer's disease in individuals diagnosed with MCI. Progression factors, including neuroimaging and vascular risk factors are also discussed. Vascular risk factors, such as hypertension, hyperlipemia and diabetes mellitus can be modulated by food, life style and treatment. The recent clinical trials for protective cognition using anti- hypertensive medication as well as statin is discussed. (author)

    ABSTRACTConsiderable international governmental support is focused on the timely diagnosis of dementia and post-diagnostic care of people with dementia. Identifying those at high risk of dementia is one approach to timely diagnosis. General practitioners (GPs) are well-placed clinicians in the community to provide both pre- and post-diagnostic dementia care. However, GPs have in the past consistently demonstrated low confidence in both diagnosing dementia and providing care for these complex patients particularly for patients in the post-diagnostic phase. It is currently unclear how future GPs view dementia care. We aimed to evaluate the current attitudes and experiences of future GPs in dementia care and their views on targeting high risk groups. All (n = 513) GP trainees were approached by email to participate in a cross-sectional web and paper-based survey in the North of England. A further reminder was sent out two months after the initial invitation. We received 153 responses (29.8% response rate, 66.7% female, average age 31 (range 25-55 years old). The main difficulties encountered included coordinating supporting services for carers and the person with dementia and responding to co-existing behavioral and psychiatric symptoms. Further education in dementia management was considered to be important by respondents. GP trainees were generally very positive about their future role in caring for people with dementia, particularly in the area of earlier diagnosis via identification of high-risk individuals. Future GPs in one area of England are very positive about their key role in dementia care. In order to facilitate the delivery of high quality, community-based care, work is required to establish core post-diagnostic dementia support services. Further research is needed to identify effective systems to enable accurate assessment and to ensure earlier diagnosis in high-risk groups.

    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.

    Dementia is one of the most common diseases in the elderly population and is getting more and more important with the ageing of the population. A radiologic structural examination with CT or MRI is meanwhile a standard procedure in the diagnostic work up of patients with dementia syndrome. Radiology enables an early diagnosis and a differential diagnosis between different causes of dementia. Because structural changes occur only late in the disease process, a more detailed structural analysis using volumetric techniques or the use of functional imaging techniques is mandatory. These days, structural imaging uses MRI which enables to detect early atrophic changes at the medial temporal lobe with focus on the amygdala hippocampal complex. These changes are also present in the normal ageing process. In patients with Alzheimer's disease, however, they are more rapid and more pronounced. The use of functional imaging methods such as perfusion MRI, diffusion MRI or fMRI allow new insights into the pathophysiologic changes of dementia. The article gives an overview of the current status of structural imaging and an outlook into the potential of functional imaging methods. Detailed results of structural and functional imaging are presented in other articles of this issue. (orig.) [de

    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.

    Measurement of local cerebral glucose metabolism (lCMRGlc) by positron emission tomography (PET) and 18 F-2-fluoro-2-deoxy-D-glucose (FDG) has become a standard technique during the past 20 years and is now available at many university hospitals in all highly developed countries. Many studies have documented a close relation between lCMRGlc and localized cognitive functions, such as language and visuoconstructive abilities. Alzheimer's disease (AD) is characterized by regional impairment of cerebral glucose metabolism in neocortical association areas (posterior cingulate, temporoparietal and frontal multimodal association cortex), whereas primary visual and sensorimotor cortex, basal ganglia, and cerebellum are relatively well preserved. In a multicenter study comprising 10 PET centers (Network for Efficiency and Standardization of Dementia Diagnosis, NEST-DD) that employed an automated voxel-based analysis of FDG PET images, the distinction between controls and AD patients was 93% sensitive and 93% specific, and even in very mild dementia (at Mini Mental Status Examination (MMSE) 24 or higher) sensitivity was still 84% at 93% specificity. Significantly abnormal metabolism in mild cognitive deficit (MCI) indicates a high risk to develop dementia within the next two years. Reduced neocortical glucose metabolism can probably be detected with FDG PET in AD on average one year before onset of subjective cognitive impairment. In addition to glucose metabolism, specific tracers for dopamine synthesis ( 18 F-F-DOPA) and for ( 11 C-MP4A) are of interest for differentiation among dementia subtypes. Cortical acetylcholine esterase activity (AChE) activity is significantly lower in patients with AD or with dementia with Lewy bodies (DLB) than in age-matched normal controls. In LBD there is also impairment of dopamine synthesis, similar to Parkinson disease. (author) 115 refs

    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

    2007-06-01

    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.

    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. Taking working memory performance into account, 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.

    To describe the clinical syndrome called dementia with Lewy bodies (DLB) and highlight its common and unique characteristics with respect to diagnosis and management. Review of the scientific literature including psychiatric literature, reports of clinical trials, and clinical practice guidelines. DLB is a clinical and histopathologic disease, which is second only to Alzheimer's disease (AD) as a cause of dementia in older adults. The clinical syndrome of DLB includes cognitive and motor deterioration reminiscent of symptoms associated with AD and Parkinson's disease (PD) respectively. The late life intersection of cognitive and motor symptoms can present significant challenges in the primary care setting. Recognizing key features of common neurodegenerative disorders is essential to accurately diagnosing and appropriately treating the growing population of older adults who suffer from AD, PD, and DLB.

    The diagnosis of cognitive impairment and dementia must reflect an increasingly diverse and aging United States population. This study compared direct testing and informant reports of cognition with clinical diagnoses of cognitive impairment and dementia between African Americans and whites. Participants in the Aging, Demographics, and Memory Study completed in-person dementia evaluations, and were assigned clinical diagnoses (by a consensus panel of dementia experts) of normal; cognitive impairment, not demented (CIND); and dementia. The Consortium to Establish a Registry for Alzheimer's Disease (CERAD) total score and the Informant Questionnaire on Cognitive Decline in the Elderly (IQCODE) were used to assess cognitive performance and reported cognitive decline. A higher CERAD total score was associated with lower odds of CIND and dementia, at comparable ratios between African Americans and whites. Higher IQCODE scores were associated with increased odds of dementia in both African Americans and whites. Higher IQCODE scores were associated with increased odds of CIND among whites, but not among African Americans. Cultural differences may influence informant reports of prevalent CIND and dementia. Our findings also highlight the need for more comparative research to establish the cultural validity of measures used to diagnose these conditions.

    Full Text Available Subcortical vascular dementia is a clinical entity, widespread, even challenging to diagnose and correctly treat. Patients with this diagnosis are old, frail, often with concomitant pathologies, and therefore, with many drugs in therapy. We tried to diagnose and follow up for three years more than 600 patients. Study subjects were men and women, not bedridden, aged 68–94 years, outpatients, recruited from June, 1st 2007 to June, 1st 2010. We examined them clinically, neurologically, with specific consideration on drug therapies. Our aim has been to define gait and imbalance problem, if eventually coexistent with the pathology of white matter and/or with the worsening of the deterioration. Drug intake interference has been detected and considered.

    We report six patients with clinically diagnosed and electrophysiologically confirmed motor neurone disease (MND), in whom communication problems were an early and dominant feature. All patients developed a progressive non-fluent aphasia culminating in some cases in complete mutism. In five cases, formal testing revealed deficits in syntactic comprehension. Comprehension and production of verbs were consistently more affected those that of nouns and this effect remained stable upon subsequent testing, despite overall deterioration. The classical signs of MND, including wasting, fasciculations and severe bulbar symptoms, occurred over the following 6-12 months. The behavioural symptoms ranged from mild anosognosia to personality change implicating frontal-lobe dementia. In three cases, post-mortem examination has confirmed the clinical diagnosis of MND-dementia. In addition to the typical involvement of motor and premotor cortex, particularly pronounced pathological changes were observed in the Brodmann areas 44 (Broca's area) and 45. The finding of a selective impairment of verb/action processing in association with the dementia/aphasia syndrome of MND suggests that the neural substrate underlying verb representation is strongly connected to anterior cortical motor systems.

    To assess the association between dementia and risk of hospital readmission and to evaluate whether the effect of dementia on hospital readmission varies according to primary diagnosis. Retrospective cohort study. Nationwide discharge database of acute care hospitals in Japan. Individuals aged 65 and older diagnosed with one of the 30 most common diagnoses and discharged from 987 hospitals between April 2014 and September 2015 (N = 1,834,378). The primary outcome was unplanned hospital readmission within 30 days. Poisson generalized estimating equation models were fitted to assess the risks of readmission for individuals with and without dementia, using primary diagnosis as a possible effect modifier and clinical factors as potential confounders. The overall prevalence of dementia was 14.7% and varied according to primary diagnosis, ranging from 3.0% in individuals with prostate cancer to 69.4% in those with aspiration pneumonia. Overall, individuals with dementia had a higher risk of hospital readmission (8.3%) than those without (4.1%) (adjusted risk ratio (aRR])=1.46, 95% confidence interval (CI)=1.44-1.49), although diagnostic category substantially modified the relationship between dementia and hospital readmission. For hip fracture, dementia was associated with greater risk of hospital readmission (adjusted risk 11.5% vs 7.9%; aRR=1.46; 95% CI=1.28-1.68); this risk was attenuated for cholecystitis (adjusted risk 12.8% vs 12.4%; aRR=1.03; 95% CI=0.90-1.18). Risk of hospital readmission associated with dementia varied according to primary diagnosis. Healthcare providers could enforce interventions to minimize readmission by focusing on comorbid conditions in individuals with dementia and specific primary diagnoses that increase their risk of readmission. © 2018, Copyright the Authors Journal compilation © 2018, The American Geriatrics Society.

    Increasing evidence supports that playing a musical instrument may benefit cognitive development and health at young ages. Whether playing an instrument provides protection against dementia has not been established. In a population-based cotwin control study, we examined the association between playing a musical instrument and whether or not the twins developed dementia or cognitive impairment. Participation in playing an instrument was taken from informant-based reports of twins' leisure activities. Dementia diagnoses were based on a complete clinical workup using standard diagnostic criteria. Among 157 twin pairs discordant for dementia and cognitive impairment, 27 pairs were discordant for playing an instrument. Controlling for sex, education, and physical activity, playing a musical instrument was significantly associated with less likelihood of dementia and cognitive impairment (odds ratio [OR] = 0.36 [95% confidence interval 0.13-0.99]). These findings support further consideration of music as a modifiable protective factor against dementia and cognitive impairment.

    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

    2004-01-01

    Purpose: The magnetization transfer ratio (MTR) is a MR-based neuroimaging procedure aiming at the quantification of the structural integrity of brain tissue. Its contribution to the differential diagnosis of dementias was examined and discussed in relation to the pathogenesis of age-related dementias. Materials and Methods: Sixty-one patients from a memory clinic were diagnosed by general physical and neuropsychiatric examination, and underwent neuropsychologic testing and neuroimaging using MRI. Their clinical diagnoses were based on standard operational research criteria. Additionally, the MTR in 10 defined regions of interest (ROI) was determined. This investigation was performed using a T1-weighted SE sequence. Average MTR values were determined in the individual ROI and their combinations and correlated with the age gender, cognitive impairment and clinical diagnosis. Sensitivity, specificity, positive and negative predictive value were determined, as well as the rate of correct classifications. Results: For cognitive healthy subjects, the MRT values correlate only mildly, though significantly, with age in the hippocampus and with gender in the dorsal corpus callosum. In contrast, the MTR in the frontal white matter correlates strongly and highly significantly with cognitive impairment in patients with dementia. The differential diagnostic assignment of Alzheimer's disease versus vascular dementia by MTR provides a correct classification of approximately 50% to 70%. PPV for no dementia vs. vascular dementia or the NPV for vascular vs. Alzheimer's disease are considerably higher exceeding 80%. For no dementia vs. Alzheimer's disease, the NPV was over 90%.

    2002-01-01

    Snoezelen, multi-sensory stimulation, provides sensory stimuli to stimulate the primary senses of sight, hearing, touch, taste and smell, through the use of lighting effects, tactile surfaces, meditative music and the odour of relaxing essential oils (Pinkney 1997). The clinical application of snoezelen has been extended from the field of learning disability to dementia care over the past decade. The rationale for its use lies in providing a sensory environment that places fewer demands on intellectual abilities but capitalizes on the residual sensorimotor abilities of people with dementia (e.g. Buettner 1999, Hope 1998). Practitioners are keen to use snoezelen in dementia care, and some encouraging results have been documented in the area of promoting adaptive behaviours (e.g. Baker, Long 1992, Spaull 1998). However, the clinical application of snoezelen often varies in form, nature, principles and procedures. Such variations not only make examination of the therapeutic values of Snoezelen difficult, but also impede the clinical development of snoezelen in dementia care. A systematic review of evidence for the efficacy of snoezelen in the care of people with dementia is therefore needed to inform future clinical applications and research directions. This review aims to examine the clinical efficacy of snoezelen for older people with dementia. "Snoezelen", "multi-sensory", "dement*", "Alzheimer*", "randomized control/single control/double control" were used as keywords to search seven electronic databases (e.g. MEDLINE, PsyLIT). The list of trials was compared with those identified from a search of the Specialized Register of the Cochrane Dementia and Cognitive Improvement Group. All RCTs in which Snoezelen or multi-sensory programmes were used as an intervention for people with dementia were included in the review. Trial data included in the review were restricted to those involving people aged over 60 years suffering from any type of dementia, except one subject

    Frontotemporal dementia (FTD) is a progressive neurodegenerative syndrome occurring between 45 and 65 years. The syndrome is also called frontotemporal lobar degeneration (FTLD). However, FTLD refers to a larger group of disorders FTD being one of its subgroups. The other subgroups of FTLD are progressive nonfluent aphasia (PFNA), and semantic dementia (SD). FTLD is characterized by atrophy of prefrontal and anterior temporal cortices. FTD occurs in 5-15% of patients with dementia and it is t...

    McEvoy, Phil; Eden, John; Plant, Rachel

    Communication skills training materials in dementia care usually focus on reminiscence. This is important because talking about past events can help people with dementia to retain their sense of self. This article examines the use of an alternative set of communication skills known as empathic curiosity, which may help to promote meaningful communication in the here and now with people who are living with dementia.

  3. 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.

    A frequent complication of the acquired immunodeficiency syndrome (AIDS) is AIDS dementia complex (ADC). The authors evaluated seven patients with AIDS (aged 28-55 years, all male) for ADC by psychiatric evaluation, neuropsychological testing, CT scanning, and IMP-SPECT. Six of seven patients exhibited cognitive or behavioral abnormalities. Neuropsychological testing showed general deficits but no cases of explicit dementia. SPECT showed marked abnormalities in two cases: posterior temporal-parietal diminution of tracer uptake in one case (posterior/anterior=0.81) and marked right/left subcortical asymmetry (1.17) in the other. In three additional cases there was asymmetric tracer uptake in the subcortical and parietal regions. CT findings were normal in all seven cases. The authors conclude that functional imaging with the use of IMP-SPECT may be a useful method to follow ADC progression and response to therapy

With the exception of dementia with Lewy bodies, which is characterized by fluctuating confusion, other disorders causing dementia persist and deteriorate over months or years, and are not characterized by fluctuations or confusional episodes, except when other medical or environmental perturbations disrupt the arousal systems of the brain (e.g. intercurrent infection, anoxia.

    This article reviews recent evidence for the relationship between extralinguistic cognitive and language abilities in dementia. A survey of data from investigations of three dementia syndromes (Alzheimer's disease, semantic dementia and progressive nonfluent aphasia) reveals that, more often than not, deterioration of conceptual organization appears associated with lexical impairments, whereas impairments in executive function are associated with sentence- and discourse-level deficits. These connections between extralinguistic functions and language ability also emerge from the literature on cognitive reserve and bilingualism that investigates factors that delay the onset and possibly the progression of neuropsychological manifestation of dementia.

    There is a clear need for brief, but sensitive and specific, cognitive screening instruments for dementia. We assessed the diagnostic accuracy of the Japanese version of Addenbrooke's Cognitive Examination (ACE) in identifying early dementia in comparison with the conventional Mini-Mental State Examination (MMSE). Standard tests for evaluating dementia screening tests were applied. A total of 201 subjects (Alzheimer's disease (AD)=65, frontotemporal dementia (FTD)=24, vascular dementia=26, dementia with Lewy bodies=11, mild cognitive impairment (MCI)=13, and controls=62) participated in this study. The reliability of the ACE was very good (alpha coefficient=0.82). In our patient series, the sensitivity for diagnosing dementia with an ACE score of ≤74 was 0.889 with a specificity of 0.987, and the sensitivity of an ACE score of ≤80 was 0.984 with a specificity of 0.867. The Japanese version of the ACE is a very accurate instrument for the detection of early dementia, and should be widely used in clinical practice. Copyright © 2009 Elsevier Ltd. All rights reserved.

    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.

    2015-01-01

    Cognitive disorders of aging represent a serious threat to the social and economic welfare of current society. It is now widely recognized that pathology related to such conditions, particularly Alzheimer’s disease, likely begins years or decades prior to the onset of clinical dementia symptoms. This revelation has led researchers to consider candidate mechanisms precipitating the cascade of neuropathological events that eventually lead to clinical Alzheimer’s disease. Insulin, a hormone with potent effects in the brain, has recently received a great deal of attention for its potential beneficial and protective role in cognitive function. Insulin resistance, which refers to the reduced sensitivity of target tissues to the favorable effects of insulin, is related to multiple chronic conditions known to impact cognition and increase dementia risk. With insulin resistance-associated conditions reaching epidemic proportions, the prevalence of Alzheimer’s disease and other cognitive disorders will continue to rise exponentially. Fortunately, these chronic insulin-related conditions are amenable to pharmacological intervention. As a result, novel therapeutic strategies that focus on increasing insulin sensitivity in the brain may be an important target for protecting or treating cognitive decline. The following review will highlight our current understanding of the role of insulin in brain, potential mechanisms underlying the link between insulin resistance and dementia, and current experimental therapeutic strategies aimed at improving cognitive function via modifying the brain’s insulin sensitivity.

  11. Does wine prevent dementia?

    2009-02-01

    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

  12. 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

    2008-06-01

    Dementias, such as Alzheimer's disease (AD) and vascular dementia, are disorders of aging populations and represent a significant economic burden. Evidence is accumulating to suggest that cardiovascular disease (CVD) risk factors may be instrumental in the development of dementia. The goal of this review was to discuss the relationship between specific CVD risk factors and dementia and how current treatment strategies for dementia should focus on reducing CVD risks. We conducted a review of the literature for the simultaneous presence of 2 major topics, cardiovascular risk factors and dementia (eg, AD). Special emphasis was placed on clinical outcome studies examining the effects of treatments of pharmacologically modifiable CVD risk factors on dementia and cognitive impairment. Lifestyle risk factors for CVD, such as obesity, lack of exercise, smoking, and certain psychosocial factors, have been associated with an increased risk of cognitive decline and dementia. Some evidence suggests that effectively managing these factors may prevent cognitive decline/dementia. Randomized, placebo-controlled trials of antihypertensive medications have found that such therapy may reduce the risk of cognitive decline, and limited data suggest a benefit for patients with AD. Some small open-label and randomized clinical trials of statins have observed positive effects on cognitive function; larger studies of statins in patients with AD are ongoing. Although more research is needed, current evidence indicates an association between CVD risk factors--such as hypertension, dyslipidemia, and diabetes mellitus--and cognitive decline/dementia. From a clinical perspective, these data further support the rationale for physicians to provide effective management of CVD risk factors and for patients to be compliant with such recommendations to possibly prevent cognitive decline/dementia.

    The clinical diagnosis of dementing diseases largely depends on the subjective interpretation of patient symptoms. Consensus panels are frequently used in research to determine diagnoses when definitive pathologic findings are unavailable. Nevertheless, research on group decision making indicates that many factors can adversely affect panel performance. To determine conditions that improve consensus panel diagnosis. Comparison of neuropathologic diagnoses with individual and consensus panel diagnoses based on clinical scenarios only, fludeoxyglucose F 18 positron emission tomography images only, and scenarios plus images. Expert and trainee individual and consensus panel deliberations using a modified Delphi method in a pilot research study of the diagnostic utility of fludeoxyglucose F 18 positron emission tomography. Forty-five patients with pathologically confirmed Alzheimer disease or frontotemporal dementia. Statistical measures of diagnostic accuracy, agreement, and confidence for individual raters and panelists before and after consensus deliberations. The consensus protocol using trainees and experts surpassed the accuracy of individual expert diagnoses when clinical information elicited diverse judgments. In these situations, consensus was 3.5 times more likely to produce positive rather than negative changes in the accuracy and diagnostic certainty of individual panelists. A rule that forced group consensus was at least as accurate as majority and unanimity rules. Using a modified Delphi protocol to arrive at a consensus diagnosis is a reasonable substitute for pathologic information. This protocol improves diagnostic accuracy and certainty when panelist judgments differ and is easily adapted to other research and clinical settings while avoiding the potential pitfalls of group decision making.

    2017-10-01

    Subjective age is a biopsychosocial marker of aging associated with a range of outcomes in old age. In the domain of cognition, feeling older than one's chronological age is related to lower cognitive performance and steeper cognitive decline among older adults. The present study examines whether an older subjective age is associated with the risk of incident cognitive impairment and dementia. Participants were 5,748 individuals aged 65 years and older drawn from the Health and Retirement Study. Measures of subjective age, cognition, and covariates were obtained at baseline, and follow-up cognition was assessed over a 2- to 4-year period. Only participants without cognitive impairment were included at baseline. At follow-up, participants were classified into one of the three categories: normal functioning, cognitive impairment without dementia (CIND), and dementia. An older subjective age at baseline was associated with higher likelihood of CIND (odds ratio [OR] = 1.18; 1.09-1.28) and dementia (OR = 1.29; 1.02-1.63) at follow-up, controlling for chronological age, other demographic factors, and baseline cognition. Physical inactivity and depressive symptoms partly accounted for these associations. An older subjective age is a marker of individuals' risk of subsequent cognitive impairment and dementia. © The Author 2016.

    Higher education is associated with a lower risk of dementia, possibly because of a higher tolerance to subclinical neurodegenerative pathology. Whether higher education also protects against dementia after clinical stroke or transient ischemic attack (TIA) remains unknown. Within the population-based Rotterdam Study, 12,561 participants free of stroke, TIA and dementia were followed for occurrence of stroke, TIA and dementia. Across the levels of education, associations of incident stroke or TIA with subsequent development of dementia and differences in cognitive decline following stroke or TIA were investigated. During 124,862 person-years, 1,463 persons suffered a stroke or TIA, 1,158 persons developed dementia, of whom 186 developed dementia after stroke or TIA. Risk of dementia after a stroke or TIA, compared to no stroke or TIA, was highest in the low education category (hazards ratio [HR] 1.46, 95% CI 1.18-1.81) followed by intermediate education category (HR 1.36, 95% CI 1.03-1.81). No significant association was observed in the high education category (HR 0.62, 95% CI 0.25-1.54). In gender stratified analyses, decrease in risk of dementia with increasing education was significant only in men. Higher education is associated with a lower risk of dementia after stroke or TIA, particularly in men, which might be explained by a higher cognitive reserve. © 2016 S. Karger AG, Basel.

    Recent research has revealed an association between hearing impairment and dementia. The objective of this study is to determine the effect of hearing impairment on dementia incidence in a longitudinal study, and whether ear, nose, and throat (ENT) specialist care, care level, institutionalization, or depression mediates or moderates this pathway. The present study used a longitudinal sample of 154,783 persons aged 65 and older from claims data of the largest German health insurer; containing 14,602 incident dementia diagnoses between 2006 and 2010. Dementia and hearing impairment diagnoses were defined according to International Classification of Diseases, Tenth Revision, codes. We used a Kaplan Meier estimator and performed Cox proportional hazard models to explore the effect of hearing impairment on dementia incidence, controlling for ENT specialist care, care level, institutionalization, and depression. Gender, age, and comorbidities were controlled for as potential confounders. Patients with bilateral (HR = 1.43, pimpairment had higher risks of dementia incidence than patients without hearing impairment. We found no significant effect for unilateral hearing impairment and other diseases of the ear. The effect of hearing impairment was only partly mediated through ENT specialist utilization. Significant interaction between hearing impairment and specialist care, care level, and institutionalization, respectively, indicated moderating effects. We discuss possible explanations for these effects. This study underlines the importance of the association between hearing impairment and dementia. Preserving hearing ability may maintain social participation and may reduce the burden associated with dementia. The particular impact of hearing aid use should be the subject of further investigations, as it offers potential intervention on the pathway to dementia. PMID:27391486

    Major depressive disorder is a likely risk factor for dementia, but some cases of major depressive disorder in older adults may actually represent a prodrome of this condition. The purpose of this study was to use neuropsychological test scores to predict conversion to dementia in a sample of depressed older adults diagnosed as nondemented at the time of neuropsychological testing. Longitudinal, with mean follow-up of 5.45 years. Outpatient depression treatment study at Duke University. Thirty nondemented individuals depressed at the time of neuropsychological testing and later diagnosed with incident dementia; 149 nondemented individuals depressed at the time of neuropsychological testing and a diagnosis of cognitively normal. All participants received clinical assessment of depression, were assessed to rule out prevalent dementia at the time of study enrollment, completed neuropsychological testing at the time of study enrollment, and were diagnosed for cognitive disorders on an annual basis. Nondemented, acutely depressed older adults who converted to dementia during the study period exhibited broadly lower cognitive performances at baseline than acutely depressed individuals who remained cognitively normal. Discriminant function analysis indicated that 2 neuropsychological tests, Recognition Memory (from the Consortium to Establish a Registry for Alzheimer's Disease neuropsychological battery) and Trail Making B, best predicted dementia conversion. Depressed older adults with cognitive deficits in the domains of memory and executive functions during acute depression are at higher risk for developing dementia. Some cases of late-life depression may reflect a prodrome of dementia in which clinical manifestation of mood changes may co-occur with emerging cognitive deficits.

Both forms of dementia are posing greater risk to the world population and are increasing at a faster rate. In the past we have reported the induction of vascular dementia by experimental diabetes. This study investigates the role of vildagliptin, a dipeptidyl peptidase-4 inhibitor in the pharmacological interdiction of pancreatectomy diabetes induced vascular endothelial dysfunction and subsequent vascular dementia in rats. Attentional set shifting and Morris water-maze test were used for assessment of learning and memory. Vascular endothelial function, blood brain barrier permeability, serum glucose, serum nitrite/nitrate, oxidative stress (viz. aortic superoxide anion, brain thiobarbituric acid reactive species and brain glutathione), brain calcium and inflammation (myeloperoxidase) were also estimated. Pancreatectomy diabetes rats have shown impairment of endothelial function, blood brain barrier permeability, learning and memory along with increase in brain inflammation, oxidative stress and calcium. Administration of vildagliptin has significantly attenuated pancreatectomy induced impairment of learning, memory, endothelial function, blood brain barrier permeability and biochemical parameters. It may be concluded that vildagliptin, a dipeptidyl peptidase-4 inhibitor may be considered as potential pharmacological agents for the management of pancreatectomy induced endothelial dysfunction and subsequent vascular dementia. The selective modulators of dipeptidyl peptidase-4 may further be explored for their possible benefits in vascular dementia. Copyright © 2015 Elsevier Inc. All rights reserved.

    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.

    Abstract Periodontitis is a systemic and chronic inflammatory disease associated with multiple physical conditions. Distress and depression are other problems affecting the progression of periodontitis. However, the causal relationship between depression and periodontitis has not been adequately investigated. This aim of this study was to determine the association between periodontitis and the subsequent development of depression. We identified 12,708 patients with newly diagnosed periodontitis from 2000 to 2005 and 50,832 frequency-matched individuals without periodontitis. Both groups were followed until diagnosed with depression, withdrawal from the National Health Insurance program, or the end of 2011. The association between periodontitis and depressio was analyzed using Cox proportional hazard regression models. The incidence density rate of depression was higher in the periodontitis group than in the nonperiodontitis group, with an adjusted hazard ratio of 1.73 (95% confidence interval 1.58–1.89) when adjusting for sex, age, and comorbidity. Cox models revealed that periodontitis was an independent risk factor for depression in patients, except for comorbidities of diabetes mellitus (DM), alcohol abuse, and cancer. Periodontitis may increase the risk of subsequent depression and was suggested an independent risk factor regardless of sex, age, and most comorbidities. However, DM, alcohol abuse, and cancer may prevent the development of subsequent depression because of DM treatment, the paradoxical effect of alcohol, and emotional distress to cancer, respectively. Prospective studies on the relationship between periodontitis and depression are warranted. PMID:26705230

    This chapter aims to encourage scientists and others interested in the use of animal models of disease – specifically, in the study of dementia – to engage in ethical reflection. It opens with a general discussion of the moral acceptability of animal use in research. Three ethical approaches...... are here distinguished. These serve as points of orientation in the following discussion of four more specific ethical questions: Does animal species matter? How effective is disease modelling in delivering the benefits claimed for it? What can be done to minimize potential harm to animals in research? Who...... bears responsibility for the use of animals in disease models?...

    Artistic ability and creativity are defining characteristics of human behavior. Behavioral neurology, as a specialty, believes that even the most complex behaviors can be modeled and understood as the summation of smaller cognitive functions. Literature from individuals with specific brain lesions has helped to map out these smaller regions of cognitive abilities. More recently, models based on neurodegenerative conditions, especially from the frontotemporal dementias, have allowed for greater nuanced investigations into the various functional anatomies necessary for artistic behavior and possibly the underlying networks that promote creativity. © 2013 Elsevier B.V.

    To investigate the association between statin use, incident dementia, and Alzheimer disease (AD) in a prospective elderly African American cohort. Two stage design with a screening interview followed by a comprehensive in-home assessment conducted over an eight-year period. Diagnoses of incident AD and dementia were made by consensus. Statin use was collected at each evaluation. Measurements of low-density lipoprotein cholesterol (LDL), C-reactive protein (CRP) and APOE genotype were obtained from baseline blood samples. Logistic regression models were used to test the association of statin use on incident dementia and AD and its possible association with lipid and CRP levels. Indianapolis, Indiana. From an original cohort of 2629 participants, a subsample of 974 African Americans aged >70 years with normal cognition, at least one follow up evaluation, complete statin information, and biomarker availability were included. Incident dementia and incident AD. After controlling for age at diagnosis, sex, education level, presence of the APOE ε4 allele and history of stroke for the incident dementia model, baseline use of statins was associated with a significantly decreased risk of incident dementia (OR=.44, P=.029) and incident AD (OR=.40, P=.029). The significant effect of statin use on reduced AD risk and trend for dementia risk was found only for those participants who reported consistent use over the observational period (incident AD: P=.034; incident dementia: P=.061). Additional models found no significant interaction between baseline statin use, baseline LDL, or CRP level and incident dementia/AD. Consistent use of statin medications during eight years of follow-up resulted in significantly reduced risk for incident AD and a trend toward reduced risk for incident dementia.

    Memory impairment has been proposed as the most common early sign of Alzheimer's disease (AD). The aims of this work were to evaluate the risk of progression from mild memory impairment/no dementia (MMI/ND) to clinically diagnosable AD in a community-based prospective cohort and to establish the risk factors for progression from MMI/ND to AD in the elderly. Elderly subjects aged over 65 years were selected from the participants in the first Nakayama study. MMI/ND was defined as memory deficit on objective memory assessment, without dementia, impairment of general cognitive function, or disability in activities of daily living. A total of 104 MMI/ND subjects selected from 1242 community-dwellers were followed longitudinally for five years. During the five-year follow-up, 11 (10.6%) subjects were diagnosed with AD, five (4.8%) with vascular dementia (VaD), and six (5.8%) with dementia of other etiology. Logistic regression analysis revealed that diabetes mellitus (DM) and a family history of dementia (within third-degree relatives) were positively associated with progression to AD, while no factor was significantly associated with progression to VaD or all types of dementia. DM and a family history of dementia were significant risk factors for progression from MMI/ND to clinically diagnosable AD in the elderly in a Japanese community.

    Post diagnostic support (PDS) has varied definitions within mainstream dementia services and different health and social care organizations, encompassing a range of supports that are offered to adults once diagnosed with dementia until death. An international summit on intellectual disability and dementia held in Glasgow, Scotland in 2016 identified how PDS applies to adults with an intellectual disability and dementia. The Summit proposed a model that encompassed seven focal areas: post-diagnostic counseling; psychological and medical surveillance; periodic reviews and adjustments to the dementia care plan; early identification of behaviour and psychological symptoms; reviews of care practices and supports for advanced dementia and end of life; supports to carers/ support staff; and evaluation of quality of life. It also explored current practices in providing PDS in intellectual disability services. The Summit concluded that although there is limited research evidence for pharmacological or non-pharmacological interventions for people with intellectual disability and dementia, viable resources and guidelines describe practical approaches drawn from clinical practice. Post diagnostic support is essential, and the model components in place for the general population, and proposed here for use within the intellectual disability field, need to be individualized and adapted to the person's needs as dementia progresses. Recommendations for future research include examining the prevalence and nature of behavioral and psychological symptoms (BPSD) in adults with an intellectual disability who develop dementia, the effectiveness of different non-pharmacological interventions, the interaction between pharmacological and non-pharmacological interventions, and the utility of different models of support.

    Evidence-based data on prevalence and risk factors of suicidal intentions and behavior in dementia are as scarce as the data on assisted dying. The present literature review aimed on summarizing the current knowledge and provides a critical discussion of the results. A systematic narrative literature review was performed using Medline, Cochrane Library, EMBASE, PSYNDEX, PSYCINFO, Sowiport, and Social Sciences Citation Index literature. Dementia as a whole does not appear to be a risk factor for suicide completion. Nonetheless some subgroups of patients with dementia apparently have an increased risk for suicidal behavior, such as patients with psychiatric comorbidities (particularly depression) and of younger age. Furthermore, a recent diagnosis of dementia, semantic dementia, and previous suicide attempts most probably elevate the risk for suicidal intentions and behavior. The impact of other potential risk factors, such as patient's cognitive impairment profile, behavioral disturbances, social isolation, or a biomarker based presymptomatic diagnosis has not yet been investigated. Assisted dying in dementia is rare but numbers seem to increase in regions where it is legally permitted. Most studies that had investigated the prevalence and risk factors for suicide in dementia had significant methodological limitations. Large prospective studies need to be conducted in order to evaluate risk factors for suicide and assisted suicide in patients with dementia and persons with very early or presymptomatic diagnoses of dementia. In clinical practice, known risk factors for suicide should be assessed in a standardized way so that appropriate action can be taken when necessary.

    Background: previous studies have indicated a prevalence of dementia in older admissions of ∼42% in a single London teaching hospital, and 21% in four Queensland hospitals. However, there is a lack of published data from any European country on the prevalence of dementia across hospitals and between patient groups. Objective: to determine the prevalence and associations of dementia in older patients admitted to acute hospitals in Ireland. Methods: six hundred and six patients aged ≥70 years were recruited on admission to six hospitals in Cork County. Screening consisted of Standardised Mini-Mental State Examination (SMMSE); patients with scores dementia; with 29% in public hospitals. Prevalence varied between hospitals (P dementia had a previous diagnosis. Patients with dementia were older and frailer, with higher co-morbidity, malnutrition and lower functional status (P dementia (57%) on admission. Conclusion: dementia is common in older people admitted to acute hospitals, particularly in acute medical admissions, and rural hospitals, where services may be less available. Most dementia is not previously diagnosed, emphasising the necessity for cognitive assessment in older people on presentation to hospital. PMID:26420638

    This review considers the role of functional brain imaging techniques in the dementias. The substantial assistance that especially single-photon emission tomography and positron emission tomography can play in the initial diagnosis of dementia and in the differential diagnosis of the specific dementing disorder is discussed. These techniques alone essentially match the sensitivity and specificity of clinical diagnoses in distinguishing Alzheimer's dementia (AD) from age-matched controls, from frontal lobe dementia and vascular dementia, and even from Lewy body dementia. Newer analytic techniques such as voxel-based correlational analyses and discriminant function analyses enhance the power of such differential diagnoses. Functional brain imaging techniques can also significantly assist in patient screening for clinical trials. The correlation of the observed deficits with specific patterns of cognitive abnormalities permits enhanced patient management and treatment planning and improved longitudinal assessment of outcome. It is also noteworthy that the classic abnormalities of temporoparietal and posterior cingulate hypoperfusion or hypometabolism appear to be present prior to symptom onset. These abnormalities predict progression to AD in the presence of the earliest of symptoms, and are present even in cognitively normal but at-risk subjects, with a severity proportional to the risk status. Even greater predictive ability for progression to AD is obtained by combining measures of perfusion or metabolism with risk factors, tau protein levels, hippocampal N-Acetyl aspartate concentrations, or hippocampal volume measures.

    2016-01-01

    ABSTRACT Objectives: To interrogate the concept of personhood and its application to care practices for people with dementia. Method: We outline the work of Tom Kitwood on personhood and relate this to conceptualisations of personhood in metaphysics and in moral philosophy. Results: The philosophical concept of personhood has a long history. The metaphysical tradition examines the necessary and sufficient qualities that make up personhood such as agency, consciousness, identity, rationality and second-order reflexivity. Alternative viewpoints treat personhood as a matter of degree rather than as a superordinate category. Within moral philosophy personhood is treated as a moral status applicable to some or to all human beings. Conclusion: In the light of the multiple meanings attached to the term in both metaphysics and moral philosophy, personhood is a relatively unhelpful concept to act as the foundation for developing models and standards of care for people with dementia. Care, we suggest, should concentrate less on ambiguous and somewhat abstract terms such as personhood and focus instead on supporting people's existing capabilities, while minimising the harmful consequences of their incapacities.

    Total Tau concentration in cerebrospinal fluid (CSF) is widely used as a biomarker in the diagnosis of neurodegenerative process primarily in Alzheimer's disease (AD). A particularly high Tau level may indicate AD but may also be associated with Creutzfeldt-Jakob disease (CJD). In such situations little is known about the distribution of differential diagnoses. Our study aimed to describe the different diagnoses encountered in clinical practice for patients with dementia and CSF Tau levels over 1000 pg/ml. We studied the p-Tau/Tau ratio to specify its ability to distinguish AD from CJD. Patients (n = 202) with CSF Tau levels over 1000 pg/ml were recruited in three memory clinics in France. All diagnoses were made using the same diagnostic procedure and criteria. Patients were diagnosed with AD (n = 148, 73.2%), mixed dementia (n = 38, 18.8%), CJD, vascular dementia (n = 4, 2.0% for each), Lewy body dementia, and frontotemporal dementia (n = 3, 1.5% for each). Dispersion of CSF Tau levels clearly showed an overlap between all diagnoses. Using the p-Tau/Tau ratio suggestive of CJD (<0.075), all CJD patients were correctly categorized and only two AD patients were miscategorized. This ratio was highly associated with CJD compared to AD (p < 0.0001). Our study showed that in clinical practice, extremely high CSF Tau levels are mainly related to diagnosis of AD. CJD patients represent a minority. Our results support a sequential interpretation algorithm for CSF biomarkers in dementia. High CSF Tau levels should alert clinicians to check the p-Tau/Tau ratio to consider a probable diagnosis of CJD.

    This updated Cochrane Review of reminiscence therapy (RT) for dementia was first published in 1998, and last updated in 2005. RT involves the discussion of memories and past experiences with other people using tangible prompts such as photographs or music to evoke memories and stimulate conversation. RT is implemented widely in a range of settings using a variety of formats. To assess the effects of RT on people living with dementia and their carers, taking into account differences in its implementation, including setting (care home, community) and modality (group, individual). We searched ALOIS (the Cochrane Dementia and Cognitive Improvement Group's Specialized Register) on 6 April 2017 using the search term 'reminiscence.' We included all randomised controlled trials of RT for dementia in which the duration of the intervention was at least four weeks (or six sessions) and that had a 'no treatment' or passive control group. Outcomes of interest were quality of life (QoL), cognition, communication, behaviour, mood and carer outcomes. Two authors (LOP and EF) independently extracted data and assessed risk of bias. Where necessary, we contacted study authors for additional information. We pooled data from all sufficiently similar studies reporting on each outcome. We undertook subgroup analysis by setting (community versus care home) and by modality (individual versus group). We used GRADE methods to assess the overall quality of evidence for each outcome. We included 22 studies involving 1972 people with dementia. Meta-analyses included data from 16 studies (1749 participants). Apart from six studies with risk of selection bias, the overall risk of bias in the studies was low.Overall, moderate quality evidence indicated RT did not have an important effect on QoL immediately after the intervention period compared with no treatment (standardised mean difference (SMD) 0.11, 95% confidence interval (CI) -0.12 to 0.33; I 2 = 59%; 8 studies; 1060 participants

    To determine whether periodontitis is a modifiable risk factor for dementia. Prospective cohort study. National Health Insurance Research Database in Taiwan. Individuals aged 65 and older with periodontitis (n = 3,028) and an age- and sex-matched control group (n = 3,028). Individuals with periodontitis were compared age- and sex-matched controls with for incidence density and hazard ratio (HR) of new-onset dementia. Periodontitis was defined according to International Classification of Diseases, Ninth Revision, Clinical Modification (ICD-9-CM) codes 523.3-5 diagnosed by dentists. To ensure diagnostic validity, only those who had concurrently received antibiotic therapies, periodontal treatment other than scaling, or scaling more than twice per year performed by certified dentists were included. Dementia was defined according to ICD-9-CM codes 290.0-290.4, 294.1, 331.0-331.2. After adjustment for confounding factors, the risk of developing dementia was calculated to be higher for participants with periodontitis (HR = 1.16, 95% confidence interval = 1.01-1.32, P = .03) than for those without. Periodontitis is associated with greater risk of developing dementia. Periodontal infection is treatable, so it might be a modifiable risk factor for dementia. Clinicians must devote greater attention to this potential association in an effort to develop new preventive and therapeutic strategies for dementia. © 2016, Copyright the Authors Journal compilation © 2016, The American Geriatrics Society.

    With the ageing of the general population, demand has grown for measures to prevent hospitalization for dementia, which can exacerbate problems associated with activities of daily living in elderly individuals. Anticholinergic medication has been shown to cause falls, delirium, and cognitive impairment in aged patients. However, the risk of hospitalization associated with the administration of anticholinergics is unclear. We analyzed the records of 61 outpatients (26 men, 35 women; mean age: 78 ± 7 years; mean follow-up period: 420 days) diagnosed with dementia (Alzheimer's disease: n = 45; dementia with Lewy bodies: n = 3; undifferentiated n = 13) and prescribed anti-dementia drugs between May 2013 and December 2014. Medication history was noted, and the patients were divided into two groups according to the Anticholinergic Risk Scale: with risk (n = 13) and without risk (n = 48). Outcome was judged based on an end-point of hospitalization or death. Kaplan-Meier survival and Cox proportional hazard analyses were performed. Eight patients with anticholinergic risk and 12 without anticholinergic risk reached the end-point (P dementia. The Anticholinergic Risk Scale findings were shown to be a strong predictor of hospitalization for patients with dementia. We should evaluate the anticholinergic burden before initiating anti-dementia therapy. © 2018 Japanese Psychogeriatric Society.

    The Addenbrooke's Cognitive Examination (ACE) is reported to be a highly sensitive and specific "bedside" test for the diagnosis of dementia, but large pragmatic studies of its use in day-to-day clinical practice are lacking. This study measured diagnostic accuracy of ACE in a large cohort of consecutive patients referred to a dedicated Cognitive Function Clinic. Consecutive new referrals over a 3.5-year period were administered the ACE (n=285). ACE scores and subscores (VLOM ratio) were compared to clinical diagnoses of dementia and dementia subtype, established on the basis of widely accepted diagnostic criteria and at least 12-month follow-up. ACE had good sensitivity, specificity, and positive predictive value for the diagnosis of dementia, with excellent diagnostic accuracy as measured by area under the receiver operating characteristic curve. However, a lower cutoff than that used in the index paper was required for optimum test sensitivity and specificity. ACE VLOM ratio subscore for the differential diagnosis of Alzheimer's disease and frontotemporal dementia proved less accurate. This study suggests that ACE is useful for the diagnosis of dementia in routine clinical practice but that other instruments may be required for the differential diagnosis of the dementia syndrome.

    Parkinson's disease (PD) is frequently compounded by dementia and depression. Yet local total estimates on the prevalence of PD with dementia/depression are still lacking. These are socioeconomically important, especially for the eastern federal states in Germany due to the demographic structures. We conducted a two-staged total estimation in the area of Dresden. First, all local office-based neurologists, hospitals and retirement homes were asked to list their patients/residents with PD on a single study day. Then a random sample of patients/home residents was neuropsycholoigcally examined, including the Mini-mental-state exam and the Montgomery-Asberg Depression rating scale. Dementia was diagnosed according to DSM-IV criteria. Overall, 886 PD cases (95 % CI: 809 - 926) were estimated, of which 252 (95 % CI: 226 - 279) suffered from dementia and 216 (95 % CI: 191 - 242) from depression. Dementia rates increased by age with 13.8 % (≤ 65 years) to 40.2 % (≥ 76 years). Depression rates ranged from 23.3 % to 28.0 %. Overall, 20.6 % of all ambulatory treated PD patients and 85.7 % of all home residents with PD had dementia. The prevalence of PD in Dresden dovetails with previous reported estimates. Dementia and depression are frequent complications in outpatients as well as home residents with PD. © Georg Thieme Verlag KG Stuttgart · New York.

    People from lower socioeconomic groups have a higher risk of mortality. The impact of low socioeconomic status on survival among older adults with dementia and depression remains unclear. To investigate the association between socioeconomic status and mortality in people with dementia and late-life depression in China. Using Geriatric Mental Status - Automated Geriatric Examination for Computer Assisted Taxonomy (GMS-AGECAT) we interviewed 2978 people aged ⩾60 years in Anhui, China. We characterised baseline socioeconomic status and risk factors and diagnosed 223 people with dementia and 128 with depression. All-cause mortality was followed up over 5.6 years. Individuals with dementia living in rural areas had a three times greater risk of mortality (multivariate adjusted hazard ratio (HR) = 2.96, 95% CI 1.45-6.04) than those in urban areas, and for those with depression the HR was 4.15 (95% CI 1.59-10.83). There were similar mortality rates when comparing people with dementia with low v. high levels of education, occupation and income, but individuals with depression with low v. high levels had non-significant increases in mortality of 11%, 50% and 55% respectively Older adults with dementia and depression living in rural China had a significantly higher risk of mortality than urban counterparts. Interventions should be implemented in rural areas to tackle survival inequality in dementia and depression. Royal College of Psychiatrists.

    As many as 50% of people satisfying diagnostic criteria for dementia are undiagnosed. A team-based training program for dementia screening and management was developed targeting four professions (medicine, nursing, pharmacy, social work) whose scope of practice involves dementia care. An interprofessional group of 10 faculty members was trained to facilitate four interactive competency stations on dementia screening, differential diagnoses, dementia management and team care planning, and screening for and managing caregiver stress. Registrants were organized into teams of five members, with at least one member of each profession per team. The teams rotated through all stations, completing assigned tasks through interprofessional collaboration. A total of 117 professionals (51 physicians, 11 nurses, 20 pharmacists, 24 social workers, 11 others) successfully completed the program. Change scores showed significant improvements in overall competence in dementia assessment and intervention (very low = 1; very high = 5; average change 1.12, P managing medication (average change 0.86, P team-based interprofessional competency training is a team teaching model that can be used to enhance competency in dementia screening and management in medical, nursing, pharmacy, and social work practitioners. © 2016, Copyright the Authors Journal compilation © 2016, The American Geriatrics Society.

  8. Role of neuropsychological assessment in the differential diagnosis of Alzheimer's disease and vascular dementia

    Directory of Open Access Journals (Sweden)

    Érica Maria Lima Pimentel

    Full Text Available Abstract The prevalence of dementia increases significantly from the age of 65 years, doubling every five years thereafter. Alzheimer's disease (AD and vascular dementia (VaD constitute the two main dementia types. Differentiating them encompasses anamnesis, neurological examination, laboratory and neuroimaging exams and neuropsychological assessment. Neuropsychological assessment produces different findings for each dementia type, and reveals those areas most impaired as well as those most preserved. The aim of the present article was to describe the role of neuropsychology in diagnosing dementia and achieving a differential diagnosis between AD and VaD. A general overview follows of the most widely known instruments used to assess cognitive function in dementia, and the cognitive changes seen in AD and VaD. The conclusion drawn was that there is significant overlap in cognitive changes between both these dementia types, while each type has its own specific characteristics which are identifiable and quantifiable on neuropsychological assessments and provide the basis for reaching a differential diagnosis.

    To describe a contemporary artistic educational program based on photographic cyanotype techniques and to present the results of the program carried out with older people with early dementia. We determined whether these people could participate in the program, their viewpoint about it, and what this program could contribute to their experience. Twenty-one people diagnosed with mild or moderate dementia participated in a series of artistic education workshops. While conducting the workshops, participant observation was carried out, and the participants' engagement was assessed. Upon completing the series, five focus groups were held with the participants with dementia, and another focus group with their professional caretakers. We observed the participants' high level of commitment to the activity and their interest in learning new things. We also observed the participants' satisfaction during the creative process and with their results. The artistic activities not only reinforced the feelings of capacity of the participants with early dementia but also transmitted a positive image of them. Dementia was not an obstacle to participation in the program, which was an opportunity for creativity, learning, enjoyment, and communication for people with dementia. In the authors' opinion, facilitating access to art and artistic education to people with early dementia can contribute to enforcing their rights and to improving the care system.

    To quantify longitudinal change in financial and health literacy and examine the associations of declining literacy with incident Alzheimer's disease (AD) dementia and mild cognitive impairment (MCI). Data came from 799 participants of an ongoing cohort study. Literacy was measured using a battery of 32 questions. Clinical diagnoses were made annually following uniform structured procedures. The associations of declining literacy with incident AD dementia and MCI were tested using a joint model for longitudinal and time-to-event data. We observed an overall decline in total literacy score over up to 6 years of follow-up ( p literacy was associated with higher risks for incident AD dementia (hazard ratio = 4.526, 95% confidence interval = [2.993, 6.843], p literacy among community-dwelling older persons predicts adverse cognitive outcomes and serves as an early indicator of impending dementia.

    Late-life depression is frequently accompanied by cognitive impairments. Whether these impairments indicate a prodromal state of dementia, or are a symptomatic expression of depression per se is not well-studied. In a cohort of very old initially non-demented primary care patients (n = 2,709, mean age = 81.1 y), cognitive performance was compared between groups of participants with or without elevated depressive symptoms and with or without subsequent dementia using ANCOVA (adjusted for age, sex, and education). Logistic regression analyses were computed to predict subsequent dementia over up to six years of follow-up. The same analytical approach was performed for lifetime major depression. Participants with elevated depressive symptoms without subsequent dementia showed only small to medium cognitive deficits. In contrast, participants with depressive symptoms with subsequent dementia showed medium to very large cognitive deficits. In adjusted logistic regression models, learning and memory deficits predicted the risk for subsequent dementia in participants with depressive symptoms. Participants with a lifetime history of major depression without subsequent dementia showed no cognitive deficits. However, in adjusted logistic regression models, learning and orientation deficits predicted the risk for subsequent dementia also in participants with lifetime major depression. Marked cognitive impairments in old age depression should not be dismissed as "depressive pseudodementia", but require clinical attention as a possible sign of incipient dementia. Non-depressed elderly with a lifetime history of major depression, who remained free of dementia during follow-up, had largely normal cognitive performance.

    Full Text Available The Swedish Dementia Registry (SveDem was developed with the aim to improve the quality of diagnostic work-up, treatment and care of patients with dementia disorders in Sweden.SveDem is an internet based quality registry where several indicators can be followed over time. 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.

  16. Adipocyte-derived factors in age-related dementia and their contribution to vascular and Alzheimer pathology.

    Ishii, Makoto; Iadecola, Costantino

    2016-05-01

    Age-related dementia is increasingly recognized as having a mixed pathology, with contributions from both cerebrovascular factors and pathogenic factors associated with Alzheimer's disease (AD). Furthermore, there is accumulating evidence that vascular risk factors in midlife, e.g., obesity, diabetes, and hypertension, increase the risk of developing late-life dementia. Since obesity and changes in body weight/adiposity often drive diabetes and hypertension, understanding the relationship between adiposity and age-related dementia may reveal common underlying mechanisms. Here we offer a brief appraisal of how changes in body weight and adiposity are related to both AD and dementia on vascular basis, and examine the involvement of two key adipocyte-derived hormones: leptin and adiponectin. The evidence suggests that in midlife increased body weight/adiposity and subsequent changes in adipocyte-derived hormones may increase the long-term susceptibility to dementia. On the other hand, later in life, decreases in body weight/adiposity and related hormonal changes are early manifestations of disease that precede the onset of dementia and may promote AD and vascular pathology. Understanding the contribution of adiposity to age-related dementia may help identify the underlying pathological mechanisms common to both vascular dementia and AD, and provide new putative targets for early diagnosis and therapy.

    Caring for a spouse diagnosed with dementia can be a stressful situation and can put the caregiving partner at risk of loss of mental health and wellbeing. The main aim of this study was to investigate the relationship between dementia and spousal mental health in a population-based sample of married couples older than 55 years of age. The association was investigated for individuals living together with their demented partner, as well as for individuals whose demented partner was living in an institution. Data on dementia were collected from hospitals and nursing homes in the county of Nord-Trøndelag, Norway. These data were combined with data on spousal mental health, which were collected in a population-based health screening: the Nord-Trøndelag Health Study (HUNT). Of 6,951 participating couples (>55 years), 131 included one partner that had been diagnosed with dementia. Our results indicate that after adjustment for covariates, having a partner with dementia is associated with lower levels of life satisfaction and more symptoms of anxiety and depression than reported by spouses of elderly individuals without dementia. Spouses living together with a partner diagnosed with dementia experienced moderately lower levels of life satisfaction (0.35 standard deviation [SD]) and more symptoms of depression (0.38 SD) and anxiety (0.23 SD) than did their non-caregiving counterparts. Having a partner with dementia that resided in a nursing home was associated with clearly lower life satisfaction. Compared with non-caregivers, these spouses reported lower levels of life satisfaction (1.16 SD), and also more symptoms of depression (0.38 SD), and more symptoms of anxiety (0.42 SD). Having a partner with dementia is associated with loss of mental health and reduced life satisfaction. The risk of adverse mental health outcomes is greatest after the partner's nursing home admission.

    Full Text Available The Italian Dementia National Plan was formulated in October 2014 by the Italian Ministry of Health in close cooperation with the regions, the National Institute of Health and the three major national associations of patients and carers. The main purpose of this strategy was to provide directive indications for promoting and improving interventions in the dementia field, not limiting to specialist and therapeutic actions, but particularly focusing on the support of patients and families throughout the pathways of care. Four main objectives are indicated: 1 promote health- and social-care interventions and policies; 2 create/strengthen the integrated network of services for dementia based on an integrated approach; 3 implement strategies for promoting appropriateness and quality of care; and 4 improve the quality of life of persons with dementia and their families by supporting empowerment and stigma reduction. These objectives and the pertaining actions are described in the present paper.

    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 application's impact on the patient's 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.

    Full Text Available Recent advances in biomarker studies on dementia are summarized here. CSF Aβ40, Aβ42, total tau, and phosphorylated tau are the most sensitive biomarkers for diagnosis of Alzheimer's disease (AD and prediction of onset of AD from mild cognitive impairment (MCI. Based on this progress, new diagnostic criteria for AD, MCI, and preclinical AD were proposed by National Institute of Aging (NIA and Alzheimer's Association in August 2010. In these new criteria, progress in biomarker identification and amyloid imaging studies in the past 10 years have added critical information. Huge contributions of basic and clinical studies have established clinical evidence supporting these markers. Based on this progress, essential therapy for cure of AD is urgently expected.

    2015-10-01

    Dementia raises many ethical issues. The present review, taking note of the fact that the stages of dementia raise distinct ethical issues, focuses on three issues associated with stages of dementia's progression: (1) how the emergence of preclinical and asymptomatic but at-risk categories for dementia creates complex questions about preventive measures, risk disclosure, and protection from stigma and discrimination; (2) how despite efforts at dementia prevention, important research continues to investigate ways to alleviate clinical dementia's symptoms, and requires additional human subjects protections to ethically enroll persons with dementia; and (3) how in spite of research and prevention efforts, persons continue to need to live with dementia. This review highlights two major themes. First is how expanding the boundaries of dementias such as Alzheimer's to include asymptomatic but at-risk persons generate new ethical questions. One promising way to address these questions is to take an integrated approach to dementia ethics, which can include incorporating ethics-related data collection into the design of a dementia research study itself. Second is the interdisciplinary nature of ethical questions related to dementia, from health policy questions about insurance coverage for long-term care to political questions about voting, driving, and other civic rights and privileges to economic questions about balancing an employer's right to a safe and productive workforce with an employee's rights to avoid discrimination on the basis of their dementia risk. The review highlights these themes and emerging ethical issues in dementia.

    Forty-seven patients diagnosed as clinically demented were imaged with 123I isopropylamphetamine (IMP). All of these patients also had a nuclear magnetic resonance (NMR) study. In those patients diagnosed as having senile dementia of the Alzheimer type a bilateral reduction in IMP uptake in the temporo-parieto-occipital region was always seen. The NMR appearances were normal in 64% of these sites. The IMP images of patients with multi-infarct dementia varied from normal to marked focal deficits. There was, however, a much closer agreement between the abnormalities seen on the IMP and NMR images. In alcoholic dementia no focal areas of reduced IMP uptake were seen, although the uptake was generally irregular. In both Korsakoff's psychosis and Huntington's chorea the IMP uptake pattern and the NMR study were normal

    Tomographic imaging of the brain was performed using a rotating slant hole collimator and [ 123 I]N-isopropyl p-iodoamphetamine (IMP) in normal subjects (n = 6) and patients with either Alzheimer's disease (n = 5) or multiple infarct dementia (n = 3). Four blinded observers were asked to make a diagnosis from the images. Normal subjects and patients with multiple infarct dementia were correctly identified. Alzheimer's disease was diagnosed in three of the five patients with this disease. One patient with early Alzheimer's disease was classified as normal by two of the four observers. Another patient with Alzheimer's disease had an asymmetric distribution of IMP and was incorrectly diagnosed as multiple infarct dementia by all four observers. Limited angle tomography of the cerebral distribution of 123 I appears to be a useful technique for the evaluation of demented patients

    2017-01-01

    Orofacial pain is a common condition in the general population. It is likely that this is also the case in older persons with a dementia. However, the assessment of (orofacial) pain in non-verbal individuals is hampered by the subjective nature of pain, and their limited communicative abilities. To overcome this drawback, several tools have been developed for the assessment of pain based on observations of pain-specific facial activities, body movements, and vocalizations. Unfortunately, none of the so far developed observational tools have been designed specifically for the assessment of orofacial pain. While the recent psychometric testing of the Orofacial MOBID Pain Scale did not yield reliable outcomes, the subsequently developed Orofacial Pain Scale for Non-Verbal Individuals (OPS-NVI) is currently being evaluated and shows good promise to be reliable and valid. Besides the assessment of orofacial pain, an important application of this instrument will be the investigation of the probable causal association between impaired chewing and cognitive decline, in which orofacial pain plays a mediating role by its negative influence on chewing ability. The identification of this negative influence will urge opinion leaders and policy makers to improve the oral health status in older persons with a dementia. Ultimately, pain-free oral functioning may lead to a higher quality of life and might help stabilizing or improving cognition in this frail and vulnerable patient population.

  14. 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.

    Few studies have examined the neuropsychiatric status of patients with dementia and cognitive impairment in the developing world despite the fact that current demographic trends suggest an urgent need for such studies. To assess the level of neuropsychiatric symptoms in community-dwelling individuals with dementia, cognitive impairment no dementia and normal cognition. Subjects were from the Ibadan site of Indianapolis-Ibadan Dementia Project with stable diagnoses of normal cognition, cognitive impairment, no dementia/mild cognitive impairment (CIND/MCI), and dementia. Informants of subjects made ratings on the neuropsychiatric inventory and blessed dementia scale; subjects were tested with the mini mental state examination. One hundred and eight subjects were included in the analytic sample, 21 were cognitively normal, 34 were demented, and 53 were CIND/MCI. The diagnostic groups did not differ in age, per cent female, or per cent with any formal education. The most frequent symptoms among subjects with CIND/MCI were depression (45.3%), apathy (37.7%), night time behavior (28.3%), appetite change (24.5%), irritability (22.6%), delusions (22.6%), anxiety (18.9%), and agitation (17.0%). Depression was significantly more frequent among the CIND/MCI and dementia (44.1%) groups compared with the normal cognition group (9.5%). Distress scores were highest for the dementia group, lowest for the normal cognition group, and intermediate for the CIND/MCI group. Significant neuropsychiatric symptomatology and distress are present among cognitively impaired persons in this community-based study of older adults in this sub-Saharan African country. Programs to assist family members of cognitively impaired and demented persons should be created or adapted for use in developing countries. Copyright © 2012 John Wiley & Sons, Ltd.

    Some infectious diseases have been found to be associated with cognitive impairment and dementia. However, the relationship between herpes zoster and dementia has received little attention. This study aimed to investigate this association as well as associations of antiviral treatments for herpes zoster and incident dementia using a large national sample. Cases were identified from the Taiwan National Health Insurance Research Database with a new diagnosis of herpes zoster (ICD-9-CM code: 053) between 1997 and 2013. Each identified individual with a case of herpes zoster was compared with 1 sex-, age-, and residence-matched control subject. Both groups were followed until the first diagnosis of dementia (ICD-9-CM codes: 290.0 to 290.4, 294.1, 331.0 to 331.2, and 331.82), withdrawal from the registry, or the end of 2013. Cox regression analyses and competing risk model were applied, adjusting for sex, age, residence, depression, autoimmune disease, ischemic stroke, traumatic brain injury, alcohol use disorder, and antiviral treatments for herpes zoster to evaluate the risk of interest. A total of 39,205 cases with herpes zoster were identified. Of the 78,410 study and comparison subjects, 4,204 were diagnosed as having dementia during a mean (SD) follow-up period of 6.22 (4.05) years. Herpes zoster was associated with a slightly increased risk of dementia in the fully adjusted model (hazard ratio [HR] = 1.11; 95% CI, 1.04-1.17). Prescriptions of antiviral therapy were associated with a reduced risk of developing dementia following the diagnosis of herpes zoster (HR = 0.55; 95% CI, 0.40-0.77). Herpes zoster was associated with an increased risk of dementia, independent of potential confounding factors. Antiviral treatment might be protective in preventing dementia in patients with herpes zoster. © Copyright 2017 Physicians Postgraduate Press, Inc.

    Cardiovascular risk factors including hypertension (HTN) have been shown to increase the risk of Alzheimer disease. The current study investigated whether individuals with HTN are more susceptible to increased cognitive decline and whether the influence of HTN on cognitive decline varied as a function of dementia severity. A total of 224 nursing home and assisted living residents, with a mean age of 84.9 (±7.6) years, were assessed longitudinally with Mini Mental State Exams (MMSEs) and Clinical Dementia Ratings (CDR). Baseline dementia status was defined by the CDR score. As described in , MMSE scores in persons with HTN and questionable dementia (CDR = 0.5) declined significantly faster than nonhypertensive questionably demented persons. Hypertensive participants did not decline significantly faster than nonhypertensive participants in persons with intact cognition (CDR = 0) or frank dementia (CDR ≥ 1). These results suggest an increased risk of subsequent cognitive decline in hypertensive individuals who are especially vulnerable to developing dementia and raises the possibility that avoiding or controlling HTN might reduce the rate of cognitive decline in cognitively vulnerable individuals, potentially delaying their conversion to full-fledged dementia.

    2015-10-01

    Although automobiles remain the mobility method of choice for older adults, late-life cognitive impairment and progressive dementia will eventually impair the ability to meet transport needs of many. There is, however, no commonly utilized method of assessing dementia severity in relation to driving, no consensus on the specific types of assessments that should be applied to older drivers with cognitive impairment, and no gold standard for determining driving fitness or approaching loss of mobility and subsequent counseling. Yet, clinicians are often called upon by patients, their families, health professionals, and driver licensing authorities to assess their patients' fitness-to-drive and to make recommendations about driving privileges. We summarize the literature on dementia and driving, discuss evidenced-based assessments of fitness-to-drive, and outline the important ethical and legal concerns. We address the role of physician assessment, referral to neuropsychology, functional screens, dementia severity tools, driving evaluation clinics, and driver licensing authority referrals that may assist clinicians with an evaluation. Finally, we discuss mobility counseling (e.g. exploration of transportation alternatives) since health professionals need to address this important issue for older adults who lose the ability to drive. The application of a comprehensive, interdisciplinary approach to the older driver with cognitive impairment will have the best opportunity to enhance our patients' social connectedness and quality of life, while meeting their psychological and medical needs and maintaining personal and public safety.

    Strategies for the involvement of primary care in the management of patients with presumed or diagnosed dementia are heterogeneous across Europe. We wanted to explore attitudes of primary care physicians (PCPs) when managing dementia: (i) the most popular cognitive tests, (ii) who had the right to initiate or continue cholinesterase inhibitor or memantine treatment, and (iii) the relationship between the permissiveness of these rules/guidelines and PCP's approach in the dementia investigations and assessment. Key informant survey. Primary care practices across 25 European countries. Four hundred forty-five PCPs responded to a self-administered questionnaire. Two-step cluster analysis was performed using characteristics of the informants and the responses to the survey. Two by two contingency tables with odds ratios and 95% confidence intervals were used to assess the association between categorical variables. A multinomial logistic regression model was used to assess the association of multiple variables (age class, gender, and perceived prescription rules) with the PCPs' attitude of "trying to establish a diagnosis of dementia on their own." Discrepancies between rules/guidelines and attitudes to dementia management was found in many countries. There was a strong association between the authorization to prescribe dementia drugs and pursuing dementia diagnostic work-up (odds ratio, 3.45; 95% CI 2.28-5.23). Differing regulations about who does what in dementia management seemed to affect PCP's engagement in dementia investigations and assessment. PCPs who were allowed to prescribe dementia drugs also claimed higher engagement in dementia work-up than PCPs who were not allowed to prescribe.

    The literature commonly evaluates those daily activities which are impaired in dementia. However, in the mild stages, people with dementia (PwD) are still able to initiate and perform many of those tasks. With a lack of research exploring variations between different dementia diagnoses, this study sought to investigate those daily activities with modest impairments in the mild stages and how these compare between Alzheimer's disease (AD), vascular dementia (VaD) and mixed dementia. Staff from memory assessment services from nine National Health Service trusts across England identified and approached informal carers of people with mild dementia. Carers completed the newly revised Interview for Deteriorations in Daily Living Activities in Dementia 2 assessing the PwD's initiative and performance of instrumental activities of daily living (IADLs). Data were analysed using analysis of variance and Chi-square tests to compare the maintenance of IADL functioning across AD, VaD, and mixed dementia. A total of 160 carers returned the Interview for Deteriorations in Daily Living Activities in Dementia 2, of which 109, 21, and 30 cared for someone with AD, VaD, and mixed dementia, respectively. There were significant variations across subtypes, with AD showing better preserved initiative and performance than VaD for several IADLs. Overall, PwD showed greater preservation of performance than initiative, with tasks such as preparing a hot drink and dressing being best maintained. Findings can help classify dementia better into subtypes in order to receive bespoke support. It suggests that interventions should primarily address initiative to improve overall functioning.

  6. [Neurocognitive disorders in DSM-5: pervasive changes in the diagnostics of dementia].

    Maier, W; Barnikol, U B

    2014-05-01

    The Diagnostic and Statistical Manual of Mental Disorders (DSM-5) proposes an innovative chapter on neurocognitive disorders (NCD) as a substitute for the dementia, delirium and amnestic disorders chapter in DSM-IV. This NCD chapter promotes a most innovative change compared to DSM-IV. While the term delirium is preserved, the commonly used term dementia does not occur as a diagnostic entity. Neurocognitive disorders are more inclusive than dementias; they also cover early prodromal stages of dementias below the DSM-IV threshold. The diagnosis of NCDs requires essentially neuropsychological testing preferentially with standardized instruments. Special focus is given to etiological subtyping taking former diagnostic consensus processes by expert groups into consideration. The subsequent more extensive concept of NCD also allows the diagnosis of etiological-specific prodromal states of cognitive impairments. The changes from DSM-IV to DSM-5 are critically discussed.

    Few studies have addressed the relationship between dementia and crime. We conducted a study of persons who got a primary or secondary diagnosis of dementia or cognitive disorder in a forensic psychiatric examination. In Sweden, annually about 500 forensic psychiatric examinations are carried out. All cases from 2008 to 2010 with the diagnoses dementia or cognitive disorder were selected from the database of the Swedish National Board of Forensic Medicine. Out of 1471 cases, there were 54 cases of dementia or cognitive disorder. Case files were scrutinized and 17 cases of dementia and 4 cases of cognitive disorder likely to get a dementia diagnosis in a clinical setting were identified and further studied. There were 18 men and 3 women; Median age 66 (n = 21; Range 35-77) years of age. Eleven men but no women had a previous criminal record. There were a total of 38 crimes, mostly violent, committed by the 21 persons. The crimes were of impulsive rather that pre-meditated character. According to the forensic psychiatric diagnoses, dementia was caused by cerebrovascular disorder (n = 4), alcohol or substance abuse (n = 3), cerebral haemorrhage and alcohol (n = 1), head trauma and alcohol (n = 2), Alzheimer's disease (n = 2), Parkinson's disease (n = 1), herpes encephalitis (n = 1) and unspecified (3). Out of four persons diagnosed with cognitive disorder, one also had delusional disorder and another one psychotic disorder and alcohol dependence. An alcohol-related diagnosis was established in ten cases. There were only two cases of Dementia of Alzheimer's type, one of whom also had alcohol intoxication. None was diagnosed with a personality disorder. All but one had a history of somatic or psychiatric comorbidity like head traumas, stroke, other cardio-vascular disorders, epilepsy, depression, psychotic disorders and suicide attempts. In this very ill group, the suggested verdict was probation in one case and different forms of care in the remaining

    The box-office as well as critical success of the 2014 major motion picture Still Alice, starring Julianne Moore in the title role and based on the bestselling novel of the same name by the Harvard-trained neuroscientist Lisa Genova (Still Alice. Simon & Schuster, New York, 2009), marked an important moment in public cultural representations of people with dementia. Still Alice tells the story of Alice Howland, an eminent scientist whose increasing memory lapses are eventually diagnosed as early-onset Alzheimer's, and chronicles the transformations in her family relationships as her husband and three children respond to her decline in different ways. Alice's husband, her son, and her older daughter all respond by turning toward science, while her younger daughter Lydia seeks to engage her mother as she is now, and turns toward art and relationships. Taking Still Alice and the figure of Lydia as an entry point, I discuss arts-focused efforts to improve the lives of people with dementia, and draw upon ongoing interview-based research on the topic of dementia and friendship, to offer an account of some of the ways that people I have spoken with are actively experimenting with art and with relationships in the face of dementia. I argue that these efforts can be understood as "moral experiements," in the sense articulated by Cheryl Mattingly (Moral Laboratories: Family Peril and the Struggle for a Good Life. University of California Press, Berkeley, 2014). Although Lydia is a fictional character, her response to Alice's dementia points toward the kinds of moral experimentation that are in fact possible, and quietly being practiced, by ordinary people every day.

    Patients with rheumatoid arthritis (RA) exhibit an increased risk of dementia. Disease-modifying antirheumatic drugs (DMARDs) are commonly used to slow RA progression, but studies investigating the relationship between DMARDs and dementia in patients with RA are lacking. We investigated the relationship between DMARDs and dementia in patients with RA. Using the National Health Insurance Research Database, patients aged ≥20years, who were newly diagnosed with RA between 2000 and 2011 were identified. Patients with RA who had dementia comprised the dementia group, and patients with RA who did not have dementia comprised the control group. The groups were matched at a 1:1 ratio by the propensity score. DMARDs were categorized into conventional synthetic DMARDs (csDMARDs) and biological DMARDs (bDMARDs). Logistic regression models were used to calculate the odds ratio and 95% confidence interval (CI) to evaluate the association between DMARD use and the risk of dementia in patients with RA. A total of 957 patients with RA and dementia, and 957 patients with RA but not dementia, were enrolled. The risk of dementia was determined to be 1.63-fold higher in patients with RA with csDMARD use than in those without csDMARD use (95% CI=1.33-2.00). No significant risk of dementia was observed in patients with RA who used bDMARDs compared with their counterparts. However, patients with RA who used hydroxychloroquine, methotrexate, and sulfasalazine exhibited significant risks of dementia, irrespective of cumulative exposure days. Patients with RA who used csDMARDs exhibit significant association with dementia. Copyright © 2017 The Authors. Published by Elsevier Inc. All rights reserved.

    2002-01-01

    Aim: Brain perfusion SPECT is used in differential diagnostics of dementia syndromes. First of all the aim is to distinguish vascular dementia from degenerative dementia and to differentiate dementia from delirium, psychiatric syndromes, depression and secondary dementia, which is important in relation to therapy. The purpose of our study was to detect significance of BP SPECT and include it into the diagnostic process in dementia syndromes. Materials and methods: 51 women and 63 men aged 55 - 88 were evaluated in the study. The patients correspond to the general criteria of dementia diagnosis. They were sent to the examination by neurological, internal and psychiatric departments and out-patient departments. All patients were examined by 99mTc ECD SPECT using a double head camera PRISM 200 VP with LEHR collimator. The scintigraphic data were evaluated by the visual and semiquantitative analysis. Results: It was established that most patients in our group had vascular dementia, while Alzheimer's disease was second. In other groups we found out dementia at strategic infarct location, e.g. in gyrus angularis in the dominant hemisphere, frontal temporal lobe dementia and alcoholic dementia. Twenty-four patients had a normal diagnosis. Fifteen of them had a somatic reason of the delirious state and were re-classified into pseudodementia. Nine patients were not diagnostically included and the examination will repeated in four months time. Conclusion: We have found out a good applicability of brain perfusion SPECT in dementia syndromes diagnosis in our work. The best diagnosticable and most specific were the findings in multi-infarct dementia, Alzheimer's disease and frontal temporal lobe dementia. When vascular dementia is concerned we can even distinguish dementia at strategic infarction location, e.g. in thalamus, basal frontal telencefalon, in gyrus angularis of the dominant hemisphere, etc

  18. Role of EEG as Biomarker in the Early Detection and Classification of Dementia

    Noor Kamal Al-Qazzaz

    2014-01-01

    Full Text Available The early detection and classification of dementia are important clinical support tasks for medical practitioners in customizing patient treatment programs to better manage the development and progression of these diseases. Efforts are being made to diagnose these neurodegenerative disorders in the early stages. Indeed, early diagnosis helps patients to obtain the maximum treatment benefit before significant mental decline occurs. The use of electroencephalogram as a tool for the detection of changes in brain activities and clinical diagnosis is becoming increasingly popular for its capabilities in quantifying changes in brain degeneration in dementia. This paper reviews the role of electroencephalogram as a biomarker based on signal processing to detect dementia in early stages and classify its severity. The review starts with a discussion of dementia types and cognitive spectrum followed by the presentation of the effective preprocessing denoising to eliminate possible artifacts. It continues with a description of feature extraction by using linear and nonlinear techniques, and it ends with a brief explanation of vast variety of separation techniques to classify EEG signals. This paper also provides an idea from the most popular studies that may help in diagnosing dementia in early stages and classifying through electroencephalogram signal processing and analysis.

    With the increasing aging population, it is predicted that there will also be a rise in the number of people with dementia. Although there is no definitive cure, early detection and access to treatment and services remains the cornerstone of management. Misinformation and poor knowledge about dementia may lead to delayed diagnosis. A study of dementia literacy was undertaken to explore current knowledge in a metropolitan city in Australia. A vignette describing an older person with symptoms of cognitive impairment was posted out to volunteers at the local hospital. The majority of participants surveyed correctly identified that the person in the vignette was suffering from symptoms of dementia or cognitive impairment. However, there was more variation with regard to types of treatment available and appropriate help-seeking behavior. Although people are able to identify symptoms of dementia when they are presented in a scenario, the reality is often not as clear. More education to improve knowledge with regard to this increasingly common disorder is required so that appropriate interventions can be made available. © 2014 Wiley Publishing Asia Pty Ltd.

    Full text: The rapid increase in dementia is directly related to the growing number of aged people in developed countries, such as Australia. This increase heightens the need for accurate dementia diagnosis to ensure treatment resources are appropriately allocated. However, current diagnostic methods are unable to determine specific dementia types limiting the effectiveness of many care plans. The lack of specialist resources in rural Australian communities presents nuclear medicine with an opportunity to make a significant impact on the management of this disease. This investigation aimed to identify how SPECT perfusion imaging could maximise its role in the management of dementia in a rural New South Wales setting. The study reviewed all Technetium 99m HMPAO SPECT brain studies over a three-year period. This included a medical record audit, review of all diagnostic imaging reports and an analysis of referral patterns. The results of this study provide compelling evidence that, even in a rural setting, brain SPECT, in conjunction with neuropsychological testing, offers high accuracy in determining the presence and type of dementia. In addition, the study found more than 30% of referrers had no training in SPECT, emphasising the importance of ensuring that brain SPECT reports, in a rural setting, educate and specify to referrers the significance and exact disease type found in the study.

    To study the impact of the use of antidepressants on dementia in German patients with depression treated in general (GPs) or psychiatric practices (PPs). Patients with a first-time documentation of depression with known severity level between 2010 and 2013 (index date) were identified by 1,126 general practitioners and 176 psychiatrists in the IMS Disease Analyzer database. We included patients between the ages of 60 and 80 years who had not previously received prescriptions for antidepressant drugs and had not been diagnosed with all-cause dementia prior to or on the index date. The main outcome of the study was the risk of dementia depending on antidepressant therapy. Cox proportional hazards models (dependent variable: incident dementia) were used to adjust for confounders and to estimate the effect of antidepressant therapy. A total of 22,838 patients treated in GPs and 33,112 patients treated in PPs were included in this study. Of those, 9,570, 30,321, and 16,059 individuals suffered from mild, moderate, and severe depression, respectively. Antidepressant drug use was associated with a decreased risk of dementia in patients affected by moderate (HR = 0.86, 95% CI: 0.77 - 0.95) or severe depression (HR = 0.83, 95% CI: 0.73 - 0.94). The use of antidepressants decreased dementia risk in patients with moderate or severe depression.

    Although evidence is mounting that personalized music has beneficial effects for long-term care residents with dementia, little research has examined the effects of personalized music for the majority of persons with dementia living at home. These individuals live at home with care partners who may also benefit from having music that is personalized for their loved one. Using the Music & Memory SM program of personalized playlists delivered via iPod Shuffles®, the current study examined the effects of the Music & Memory program for persons with dementia by using the Bath Assessment of Subjective Quality of Life in Dementia scale and a Music Listening Experience Scale developed for this study. We also administered three scales that captured care partner experiences. Transcripts of the Bath Assessment of Subjective Quality of Life in Dementia administrations at the beginning of the study and 3 months later, plus interviews about the Music & Memory program, were then analyzed using the interpretive phenomenological analysis method. Themes about the Music & Memory program and life living with dementia for from diagnosed persons and their care partners are discussed.

    No previous study of Alzheimer's disease has, to our knowledge, assessed the effect of both age at dementia onset and gender on cerebral glucose metabolic patterns. To this end, we used positron emission tomography (fludeoxyglucose F 18 method) to study 24 patients with clinical diagnoses of probable Alzheimer's disease. Comparisons of the 13 patients with early-onset dementia (less than 65 years of age) with the 11 patients with late-onset dementia (greater than 65 years of age) revealed significantly lower left parietal metabolic ratios (left posterior parietal region divided by the hemispheric average) in the early-onset group. The metabolic ratio of posterior parietal cortex divided by the relatively disease-stable average of caudate and thalamus also separated patients with early-onset dementia from those with late-onset dementia, but not men from women. Further comparisons between sexes showed that, in all brain regions studied, the 9 postmenopausal women had higher nonweighted mean metabolic rates than the 15 men from the same age group, with hemispheric sex differences of 9% on the right and 7% on the left. These results demonstrate decreased parietal ratios in early-onset dementia of Alzheimer's disease, independent of a gender effect

    To determine whether hearing loss is associated with incident physician-diagnosed dementia in a representative sample. Retrospective cohort study. English Longitudinal Study of Ageing. Adults aged 50 and older. Cross-sectional associations between self-reported (n = 7,865) and objective hearing measures (n = 6,902) and dementia were examined using multinomial-logistic regression. The longitudinal association between self-reported hearing at Wave 2 (2004/05) and cumulative physician-diagnosed dementia up to Wave 7 (2014/15) was modelled using Cox proportional hazards regression. After adjustment for potential confounders, in cross-sectional analysis, participants who had self-reported or objective moderate and poor hearing were more likely to have a dementia diagnosis than those with normal hearing (self-reported: odds ratio OR = 1.6, 95% CI = 1.1-2.4 moderate hearing; OR = 2.6, 95% CI = 1.7-3.9 poor hearing, objective: OR = 1.6, 95% CI = 1.0-2.8 moderate hearing; OR = 4.4, 95% CI = 1.9-9.9 poor hearing). Longitudinally, the hazard of developing dementia was 1.4 (95% CI = 1.0-1.9) times as high in individuals who reported moderate hearing and 1.6 (95% CI = 1.1-2.0) times as high in those who reported poor hearing. Older adults with hearing loss are at greater risk of dementia than those with normal hearing. These findings are consistent with the rationale that correction of hearing loss could help delay the onset of dementia, or that hearing loss itself could serve as a risk indicator for cognitive decline. © 2017, The Authors.

    Family dementia caregivers are at high risk of depression and burnout. We assessed the feasibility of Central Meditation and Imagery Therapy for Caregivers (CMIT-C), a novel 8-week group meditation and guided imagery group therapy program, for dementia caregivers reporting stress because of caregiving responsibilities. Twelve family dementia caregivers enrolled in CMIT-C. Primary outcomes included depression and anxiety, and secondary outcomes included insomnia, quality of life, and mindfulness. Changes over the study and 3 month follow-up were analyzed with non-parametric related samples tests. Correlations of feeling state changes from meditation diaries at 1 week were made with symptom changes post meditation training. Ten participants completed the study. Completers came to an average of 7 ± 1 sessions out of a possible 8 sessions, and turned in home practice logs of 90 ± 10% of the time. Anxiety, depression, and insomnia symptoms decreased, and mindfulness ratings improved with large effects (all p meditation practice was associated with subsequent home meditation practice, anxiety change at 8 weeks, and endpoint satisfaction with CMIT-C. Central Meditation and Imagery Therapy for Caregivers is a feasible intervention for dementia caregivers. Results suggest that this therapeutic technique can reduce symptoms of anxiety, depression, and insomnia, and increase levels of mindfulness. Early response to meditation practice predicted those with the greatest short-term benefits, and this may inform future studies of meditation. Larger controlled efficacy studies of CMIT-C for dementia caregivers are warranted. Copyright © 2014 John Wiley & Sons, Ltd.

    Early-onset dementia (EOD) is defined as dementia with onset before the age of 65 years. EOD is increasingly recognised as an important clinical and social problem with devastating consequences for patients and caregivers. Determine the annual crude incidence rate and the specific incidence rates by sex and age in patients with EOD, and the standardised rate using the last national census of the population of Argentina (NCPA), from 2010. Hospital Privado de Comunidad, Mar del Plata, Argentina, attends a closed population and is the sole healthcare provider for 17 614 people. Using the database pertaining to the Geriatric Care department, we identified all patients diagnosed with EOD between 1 January, 2005 and 31 December, 2011. EOD was defined as dementia diagnosed in patients younger than 65. The study period yielded 14 patients diagnosed with EOD out of a total of 287 patients evaluated for memory concerns. The crude annual incidence of EOD was 11 per 100 000/year (CI 95%: 6.25-19.1): 17 per 100 000 (CI 95%: 7.2-33.1) in men and 8 per 100 000 (CI 95%: 3.4-17.2) in women. We observed a statistically significant increase when comparing incidence rates between patients aged 21 to <55 years and ≥ 55 to <65 years (3 vs 22 per 100 000, P=.0014). The rate adjusted by NCPA census data was 5.8 cases of EOD habitants/year. This study, conducted in a closed population, yielded an EOD incidence rate of 11 per 100 000 inhabitants/year. To the best of our knowledge, this is the first prospective epidemiological study in Argentina and in Latin America. Copyright © 2013 Sociedad Española de Neurología. Published by Elsevier Espana.

    Accumulated evidence shows that leisure activities have a positive impact on cognitive function and dementia. This review aimed to systematically summarize the current evidence on this topic taking into account the limitations of the studies and biological plausibility for the underlying mechanisms linking cognition, dementia and leisure activities, with special attention on mental, physical and social activities. We included only longitudinal studies, with a follow-up time of at least 2 years, published in English from 1991 to March 2011 on leisure activities and cognition (n=29) or dementia (n=23) and provided some evidence from intervention studies on the topic. A protective effect of mental activity on cognitive function has been consistently reported in both observational and interventional studies. The association of mental activity with the risk of dementia was robust in observational studies but inconsistent in clinical trials. The protective effect of physical activity on the risk of cognitive decline and dementia has been reported in most observational studies, but has been less evident in interventional studies. Current evidence concerning the beneficial effect of other types of leisure activities on the risk of dementia is still limited and results are inconsistent. For future studies it is imperative that the assessment of leisure activities is standardized, for example, the frequency, intensity, duration and the type of activity; and also that the cognitive test batteries and the definition of cognitive decline are harmonized/standardized. Further, well designed studies with long follow-up times are necessary. This article is part of a Special Issue entitled: Imaging Brain Aging and Neurodegenerative disease.

    Full Text Available Physical fitness (PF has been associated with improved cognition in older age, but less is known about its effects on different cognitive domains in individuals diagnosed with dementia. We explored the associations between PF and cognitive performance in 40 healthy elderly and 30 individuals with dementia. Participants completed a battery of standardized cognitive tests (Mini-Mental State Exam, Verbal Fluency, Prospective and Retrospective Memory Questionnaire, Clock Drawing, and California Verbal Learning Test and were classified into high versus low levels of PF based on their score on the Physical Fitness Questionnaire. Analyses took into account age, gender, education, occupation, head injury, Internet use, brain training, and past levels of exercise and revealed overall benefits of PF, in particular for the people with dementia. Discriminant analysis showed high accuracy of reclassification, with most errors being due to the misclassification of dementia cases as healthy when they had high PF. The first discriminant function accounted for 83% of the variance. Using individual estimates of this function, which reflected global cognitive performance, confirmed the beneficial role of PF in dementia, even when taking into account age, past level of exercise, and the number of years since the dementia diagnosis. Finally, univariate analyses confirmed the differential sensitivity of the cognitive tests, with MMSE and clock drawing showing reliable interaction effects. This work shows that PF is associated with a reduced level of cognitive deterioration expected with dementia, especially in executive functioning and provides empirical support for the cognitive benefits of interventions promoting PF for individuals with dementia.

    Fibromyalgia is a syndrome of chronic pain and other symptoms and is associated with patient discomfort and other diseases. This nationwide matched-cohort population-based study aimed to investigate the association between fibromyalgia and the risk of developing dementia, and to clarify the association between fibromyalgia and dementia. A total of 41,612 patients of age ≥50 years with newly diagnosed fibromyalgia between January 1, and December 31, 2000 were selected from the National Health Insurance Research Database of Taiwan, along with 124,836 controls matched for sex and age. After adjusting for any confounding factors, Fine and Gray competing risk analysis was used to compare the risk of developing dementia during the 10 years of follow-up. Of the study subjects, 1,704 from 41,612 fibromyalgia patients (21.23 per 1,000 person-years) developed dementia when compared to 4,419 from 124,836 controls (18.94 per 1,000 person-years). Fine and Gray competing risk analysis revealed that the study subjects were more likely to develop dementia (hazard ratio: 2.29, 95% CI: 2.16-2.42; P dementia in this study. The study subjects with fibromyalgia had a 2.77-fold risk of dementia in comparison to the control group. Therefore, further studies are needed to elucidate the underlying mechanisms of the association between fibromyalgia and the risk of dementia.

    Spinal cord injury (SCI) can cause physical disability and psychological distress; however, whether SCI is a risk factor for dementia is unclear. This study evaluated the incidence of dementia in patients with SCI. Study participants were recruited from a nationwide cohort during 2004-2007 and categorized into SCI (patients diagnosed with SCI; n = 941) and non-SCI (age- and sex-matched controls; n = 5060) cohorts. Each participant was followed for 7 years until diagnosis of dementia or December 31, 2010, whichever occurred first. Data were subjected to Kaplan-Meier and Cox regression analyses. The incidence of dementia was significantly higher in the SCI cohort (1106 per 100,000 person-years) than in the non-SCI cohort (p < 0.001). Patients with SCI had a significantly higher risk of dementia than did those without SCI (crude hazard ratio [HR] = 2.14, 95% confidence interval [CI], 1.57-2.92, p < 0.001 vs. adjusted HR = 1.95, 95% CI, 1.43-2.67, p < 0.001). Further analysis found that there is no statistical significance of higher risk for developing Alzheimer's disease among SCI patients, but that SCI patients were at higher risk of developing other types of dementia than the control cohort (crude HR = 1.88, 95% CI, 1.33-2.63, p < 0.001 vs. adjusted HR = 1.90, 95% CI, 1.35-2.68, p < 0.001). In conclusion, patients with SCI are at high risk of dementia, and effective dementia prevention strategies are recommended for comprehensive SCI care.

    Dementia is a collective name for different degenerative brain syndromes which, according to Alzheimer's Disease International, affects approximately 35.6 million people worldwide. The latest NICE guideline for dementia highlights the value of diverse treatment options for the different stages and symptoms of dementia including non-pharmacological treatments. Relevant literature also argues for the value of interventions that acknowledge the complexity of the condition and address the person as a whole, including their physical, emotional, social and cognitive processes. At the same time, there is growing literature that highlights the capacity of the arts and embodied practices to address this complexity. Dance movement therapy is an embodied psychological intervention that can address complexity and thus, may be useful for people with dementia, but its effectiveness remains unclear. To assess the effects of dance movement therapy on behavioural, social, cognitive and emotional symptoms of people with dementia in comparison to no treatment, standard care or any other treatment. Also, to compare different forms of dance movement therapy (e.g. Laban-based dance movement therapy, Chacian dance movement therapy or Authentic Movement). Searches took place up to March 2016 through ALOIS, Cochrane Dementia and Cognitive Improvement's Specialized Register, which covers CENTRAL, a number of major healthcare databases and trial registers, and grey literature sources. We checked bibliographies of relevant studies and reviews, and contacted professional associations, educational programmes and experts from around the world. We considered randomised controlled trials (RCTs) in any language, including cross-over design and cluster-RCTs for inclusion. Studies considered had to include people with dementia, in any age group and in any setting, with interventions delivered by a dance movement therapy practitioner who (i) had received formal training (ii) was a dance movement

    There are limited data on the use of artificial intelligence methods for the diagnosis of dementia in epidemiological studies in low- and middle-income country (LMIC) settings. A culture and education fair battery of cognitive tests was developed and validated for population based studies in low- and middle-income countries including India by the 10/66 Dementia Research Group. We explored the machine learning methods based on the 10/66 battery of cognitive tests for the diagnosis of dementia based in a birth cohort study in South India. The data sets for 466 men and women for this study were obtained from the on-going Mysore Studies of Natal effect of Health and Ageing (MYNAH), in south India. The data sets included: demographics, performance on the 10/66 cognitive function tests, the 10/66 diagnosis of mental disorders and population based normative data for the 10/66 battery of cognitive function tests. Diagnosis of dementia from the rule based approach was compared against the 10/66 diagnosis of dementia. We have applied machine learning techniques to identify minimal number of the 10/66 cognitive function tests required for diagnosing dementia and derived an algorithm to improve the accuracy of dementia diagnosis. Of 466 subjects, 27 had 10/66 diagnosis of dementia, 19 of whom were correctly identified as having dementia by Jrip classification with 100% accuracy. This pilot exploratory study indicates that machine learning methods can help identify community dwelling older adults with 10/66 criterion diagnosis of dementia with good accuracy in a LMIC setting such as India. This should reduce the duration of the diagnostic assessment and make the process easier and quicker for clinicians, patients and will be useful for 'case' ascertainment in population based epidemiological studies.

    Social isolation in dementia is a growing concern as the incidence and prevalence of dementing conditions is on the rise in many societies. Positive social interactions, which foster the construction and enactment of positive interpersonal relationships and therefore positive discursive identities, make an important contribution to emotional well-being. In this article, we investigate how two women diagnosed with dementia of the Alzheimer's type use language to relate to each other and two visiting graduate students. We use Systemic Functional Linguistics as an analytical framework, specifically investigating the use of vocatives and naming, and conversational moves and exchanges.

    Full Text Available Dementia is understood as a clinical syndrome characterized by impairment in memory impairment along with cognitive deficits in other domains. Over the years, understanding about the causes of dementias has improved. Broadly, dementias can be classified as irreversible degenerative dementias and reversible dementias. Alzheimer′s disease is the prototype of degenerative dementias and is characterized by the accumulation of beta-amyloid protein (called as amyloid plaques outside the neurons and accumulation of tau protein (called tau tangles inside the neurons. Vascular dementias are characterized by cerebrovascular insults which lead to pathological brain changes that impair cognition. The pathological hallmark of Lewy body dementia is the presence of α-synuclein neuronal inclusions, also known as Lewy bodies, accompanied by neuronal loss. Frontotemporal dementias are characterized by abnormal deposits of the microtubule-associated protein tau, the trans-activation response TAR DNA-binding protein with molecular weight 43 kDa (TDP-43, and the fused in sarcoma protein. Reversible dementias are characterized by the primary illness and may not present with characteristic brain deposits as seen with many degenerative dementias.

  3. Liability for Diagnosing Malingering.

    Malingering is a medical diagnosis, but not a psychiatric disorder. The label imputes that an evaluee has intentionally engaged in false behavior or statements. By diagnosing malingering, psychiatrists pass judgment on truthfulness. Evaluees taking exception to the label may claim that the professional has committed defamation of character (libel or slander) when the diagnosis is wrong and costs the claimant money or benefits. Clinicians may counter by claiming immunity or that the diagnosis was made in good faith. This problem has come into focus in military and veterans' contexts, where diagnoses become thresholds for benefits. Through historical and literary examples, case law, and military/veterans' claims of disability and entitlement, the authors examine the potency of the malingering label and the potential liability for professionals and institutions of making this diagnosis. © 2017 American Academy of Psychiatry and the Law.

    Aims. To examine the relationship between different types of dementia and hippocampal volume. Methods. Hippocampal volume was measured using FL3D sequence magnetic resonance imaging in 26 Alzheimer's, vascular dementia, mixed dementia, and normal pressure hydrocephalus patients and 15 healthy controls and also hippocampal ratio, analyzed. Minimental scale was used to stratify patients on cognitive function impairments. Results. Hippocampal volume and ratio was reduced by 25% in Alzheimer's disease, 21% in mixed dementia, 11% in vascular dementia and 5% in normal pressure hydrocephalus in comparison to control. Also an asymmetrical decrease in volume of left hippocampus was noted. The severity of dementia increased in accordance to decreasing hippocampal volume. Conclusion. Measurement in hippocampal volume may facilitate in differentiating different types of dementia and in disease progression. There was a correlation between hippocampal volume and severity of cognitive impairment

    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.

    Full Text Available Abstract Background Nicotine may aid reaction time, learning and memory, but smoking increases cardiovascular risk. Cardiovascular risk factors have been linked to increased risk of dementia. A previous meta-analysis found that current smokers were at higher risk of subsequent dementia, Alzheimer's disease, vascular dementia and cognitive decline. Methods In order to update and examine this further a systematic review and meta-analysis was carried out using different search and inclusion criteria, database selection and more recent publications. Both reviews were restricted to those aged 65 and over. Results The review reported here found a significantly increased risk of Alzheimer's disease with current smoking and a likely but not significantly increased risk of vascular dementia, dementia unspecified and cognitive decline. Neither review found clear relationships with former smoking. Conclusion Current smoking increases risk of Alzheimer's disease and may increase risk of other dementias. This reinforces need for smoking cessation, particularly aged 65 and over. Nicotine alone needs further investigation.

    OBJECTIVE. Previous studies have shown that depression is a precursor / prodrome or susceptible state for the development of dementia. This study aimed to examine the relationship between late-onset depression and subsequent cognitive and functional decline in a cohort of non-demented older Chinese persons at their 2-year follow-up and investigate for possible predictors of cognitive decline. METHODS. A total of 81 depressed subjects and 468 non-depressed community controls were recruited. RESULTS. Subjects with late-onset depression showed significantly more incident Clinical Dementia Rating (CDR) scale decline (odds ratio = 3.87, 95% confidence interval = 2.23-6.70) and dementia (odds ratio = 3.44, 95% confidence interval = 1.75-6.77) than those without depression. A higher proportion of depressed CDR 0 subjects had CDR and functional decline than their non-depressed counterparts. Depressed CDR 0.5 subjects had significantly higher rates of functional decline and lower rates of improvement in CDR than their non-depressed counterparts. CONCLUSION. Diagnosis of depression was a robust predictor of incident very mild dementia (i.e. CDR of 0.5) and depression severity was a predictor of progression to dementia from CDR of 0.5. The association between depression and the risk of CDR decline and dementia was observed in non-demented Chinese subjects. Depression was also associated with persistent mild cognitive deficits in CDR 0.5 subjects.

    We reported a 65-year-old man who developed dementia since 50 years of age. His consciousness was clear but he was indifferent to his illness. Also, the luck of attention was recognized when we underwent examinations and the result of intellectual test varied every time we performed. His memory function was almost normal on the examination which was performed when he was cooperative. Magnetic resonance imaging (MRI) disclosed multiple tiny lesions (more than 130 in all) in cerebrum, brainstem, cerebellum and spinal cord. These lesions were compatible with multiple cavernous angioma. Most of lesions manifested high-density area on cranial CT. Though the multiplicity of foci indicated the possibility of familial occurrence, he was considered to be a sporadic case on his lineage investigation and the brain MRI of his only son. In this case, neither headache nor seizures which were known as the major clinical features of intracerebral cavernous angioma was observed. He was diagnosed as having white matter dementia characterized by attentional dysfunction, decrement of volition and less memory disturbance. We speculated that he developed symptomatic dementia by the sum of multiple minor degeneration, especially in frontal lobe white matter, caused by repeated minor bleeding from cavernous angiomas.

    Full Text Available In action teaching, assignments are created that simultaneously benefit students and society by directly connecting classroom material to a community intervention. We designed an entire course rooted in the principles of action teaching in which students facilitated the positive effects of art, nature, and music on the well-being of individuals diagnosed with dementia. Groups of three students worked with a local elderly couple, one member of whom had dementia, to create multimedia digital projects (e.g., online scrapbooks, interactive DVDs involving experiences with art or nature tailored to the needs of their specific community partners. Students met weekly with their assigned couple to discuss their families’ interests, goals for the project, and to obtain feedback on the impact of their project on their families’ well-being. Through these weekly meetings, students took an iterative approach to designing and improving their final projects, applying material learned through classroom lectures to their projects. In this field experience, students went beyond traditional lecture learning by developing a customized project that promoted the well-being of someone experiencing dementia. This course fostered values of citizenship, developed students’ research skills, and highlighted the reciprocal nature between knowledge learned in the classroom and knowledge acquired through real-world experiences.

    To explore the relationship between wandering behaviour and familiar environment in community-residing persons with dementia in Korea. Numerous non-pharmacological interventions have been developed to decrease behavioural symptoms and to increase the quality of life among persons with dementia. Although the concept of familiarity is very important and environmental interventions using the concept should have been developed for persons with dementia, no study examining even the direct relationship between familiar environment and wandering has yet been published. A descriptive, cross-sectional survey design. A convenience sample was gathered of 77 non-institutionalised, community-dwelling persons with dementia and their family caregivers in Seoul and Wonju, South Korea. Descriptive statics, Pearson's correlations, t-tests, and multiple regressions were used in the data analysis. The mean age of persons with dementia was 76.9 years (SD 8.0) and their mean cognitive level score using the Mini-Mental State Examination was 13.51 (SD 6.10). Most persons with dementia (71.4%) had been diagnosed with known types of dementia such as Alzheimer's disease, multiple infarct dementia, mixed type or Parkinson's disease with dementia. A familiar feeling with the environment was associated with cognitive impairment (r = 0.32, p familiar feeling with the environment (r = -0.56, p Familiarity and physical dependency in activities of daily living were the significant predictors for overall wandering and they explained 45% of the total variance. Cognitive impairment was the only significant predictor on the subscale of spatial disorientation. It was found that a familiar feeling with the environment was an important factor affecting persons with dementia's cognitive and functional abilities as well as specific features of wandering. However, future research using a more reliable method is necessary to confirm the findings obtained in this study. This study suggested that providing

    A number of studies have suggested associations between dementia and depression in older adults. One reason could be that these disorders share structural correlates, such as white matter lesions (WMLs) and cortical atrophy. No study has examined whether these lesions precede both dementia and depression independently of each other in the general population. Whether WMLs and cortical atrophy on computed tomography predict dementia and depression was investigated in a population-based sample of 70-year-olds (n = 380) followed over 10 years. Exclusion criteria were dementia, major depression, history of stroke and a Mini-Mental State Examination score below 26 at baseline in 2000-2001. Dementia was diagnosed according to the Diagnostic and Statistical Manual of Mental Disorders, third edition, revised, and depression according to the Diagnostic and Statistical Manual of Mental Disorders, fifth edition. Primary outcomes included dementia and major depression at 10-year follow-up. Adjusted logistic regression models, including both WMLs and temporal lobe atrophy, showed that moderate to severe WMLs [odds ratio (OR) 3.96, 95% confidence interval (CI) 1.23-12.76] and temporal lobe atrophy (OR 2.93, 95% CI 1.13-7.60) predicted dementia during a 10-year follow-up independently of major depression. Similarly, both moderate to severe WMLs (OR 3.84, 95% CI 1.25-11.76) and temporal lobe atrophy (OR 2.52, 95% CI 1.06-5.96) predicted depression even after controlling for incident dementia. White matter lesions and temporal lobe atrophy preceded 10-year incidence of both dementia and depression in 70-year-olds. Shared structural correlates could explain the reported associations between dementia and depression. These brain changes may represent independent and complementary pathways to dementia and depression. Strategies to slow progression of vascular pathology and neurodegeneration could indirectly prevent both dementia and depression in older adults. © 2015 EAN.

    2011-01-01

    Background Semantic dementia is a neurodegenerative disorder characterized by the loss of meaning of words or concepts. semantic dementia can offer potential insights into the mechanisms of content-specific delusions. Objective The authors present a rare case of semantic dementia with Cotard syndrome, a delusion characterized by nihilism or self-negation. Method The semantic deficits and other features of semantic dementia were evaluated in relation to the patient's Cotard syndrome. Results Mrs. A developed the delusional belief that she was wasting and dying. This occurred after she lost knowledge for her somatic discomforts and sensations and for the organs that were the source of these sensations. Her nihilistic beliefs appeared to emerge from her misunderstanding of her somatic sensations. Conclusion This unique patient suggests that a mechanism for Cotard syndrome is difficulty interpreting the nature and source of internal pains and sensations. We propose that loss of semantic knowledge about one's own body may lead to the delusion of nihilism or death. PMID:22054629

  14. Advanced dementia pain management protocols.

    Montoro-Lorite, Mercedes; Canalias-Reverter, Montserrat

    Pain management in advanced dementia is complex because of neurological deficits present in these patients, and nurses are directly responsible for providing interventions for the evaluation, management and relief of pain for people suffering from this health problem. In order to facilitate and help decision-makers, pain experts recommend the use of standardized protocols to guide pain management, but in Spain, comprehensive pain management protocols have not yet been developed for advanced dementia. This article reflects the need for an integrated management of pain in advanced dementia. From the review and analysis of the most current and relevant studies in the literature, we performed an approximation of the scales for the determination of pain in these patients, with the observational scale PAINAD being the most recommended for the hospital setting. In addition, we provide an overview for comprehensive management of pain in advanced dementia through the conceptual framework «a hierarchy of pain assessment techniques by McCaffery and Pasero» for the development and implementation of standardized protocols, including a four-phase cyclical process (evaluation, planning/performance, revaluation and recording), which can facilitate the correct management of pain in these patients.

    Many studies suggest that in 10-25% of cases of Alzheimer's, the most common dementia in our society, can be prevented with the elimination of some risk factors. Barnes and Yaffe found that one-third of Alzheimer's cases are attributable to depression, but in the scientific literature it is not clear if it has a real causal effect on the development of dementia. The purpose of this study is to analyse the scientific evidence on the hypothesis that depression increases the risk of developing dementia. A systematic review and a meta-analysis were performed on the scientific literature published up until the present day, searching articles that were published between 1990 and 2014. Ten of the studies found met the selection criteria -similar to a) size and characteristics of the sample (origin, age…), b) process of gathering data c) method of studying the relationship (within and/or between group comparison), and d) statistical analysis of the results- and the previously established quality. The value of odds ratio varied from 1.72 to 3.59, and the hazard ratio from 1,72 to 5.44. This indicates that the subjects with a history of depression have a higher risk of developing dementia than others who did not suffer depression. Copyright © 2015 SEGG. Published by Elsevier Espana.

    The studies on the prevalence of dementia, depression, and mild cognitive impairment (MCI) in Greece are sparse and show major variations of prevalence depending on geographical areas, nutritional habits, and the way of living. The aim of this door-to-door study was to find the prevalence of dementia, depression, and MCI in a rural Greek population. Four hundred and forty-three individuals older than 61years following the application of specific criteria were diagnosed with: normal cognition, depression, MCI with and without depression, and dementia with and without depression. Four diagnostic methods were used, 2 of which included Mungas correction for age and education. After Mungas adjustment, the results were as follows-depression: 33.9%; MCI: 15.3%; MCI with depression: 8.6%; dementia: 2.0%; and dementia with depression: 7.2%. Dementia is less prevalent compared to global data and other Greek areas. Mild cognitive impairment is more prevalent than dementia. High percentages of depression may be related to low education.

    2015-10-01

    Treatment of anxiety and depression, the most common psychiatric symptoms in older adults with mild dementia, requires innovative approaches due to the high cost and significant side effects associated with traditional pharmacological interventions. Alternative non-pharmacological therapies, such as music, when used in conjunction with pharmacological treatment, have the potential to alleviate symptoms of anxiety and depression in older adults diagnosed with mild dementia. The purpose of this review was to examine the evidence of music's efficacy in improving symptoms of anxiety and depression in older adults with mild dementia. Four databases (Medline, CINAHL, PsychInfo, PubMed) were searched using the terms "music," "music therapy," "music intervention," "singing," "dementia," "anxiety," and/or "depression," identifying ten studies that met the inclusion and exclusion criteria. The poor methodological rigor of the studies precluded reaching consensus on the efficacy of a music intervention in alleviating symptoms of anxiety and depression in older adults with mild dementia. There was inconclusive evidence as to whether music interventions are effective in alleviating symptoms of anxiety and depression in older adults with mild dementia due to the poor methodological rigor. However, with improved designs guided by a deeper understanding of how music engages the aging brain, music may emerge as an important adjunct therapy to improving the lives of older adults with mild dementia.

    2014-01-01

    Objective To estimate the prevalence of both dementia and depression among community-dwelling older Americans, and to determine if hospitalization is independently associated with dementia or depression in this population. Method This cross-sectional study utilized data from a nationally representative, population-based sample of 7,197 community-dwelling adults ≥ 65 years old interviewed in 2011 as part of the National Health and Aging Trends Study. Information on hospitalizations was obtained from self or proxy-report. Possible and probable dementia was assessed according to a validated algorithm. Depressive symptoms were assessed with the Patient Health Questionnaire-2. Results An estimated 3.1 million community-dwelling older Americans may have dementia, and approximately 5.3 million may have substantial depressive symptoms. After adjusting for demographic and social characteristics, medical diagnoses, smoking history, serious falls, and pain symptoms, being hospitalized in the previous year was independently associated with greater odds of probable dementia (odds ratio [OR]: 1.42, 95% confidence interval[95%CI]: 1.16, 1.73) and substantial depressive symptoms (OR: 1.60, 95%CI: 1.29, 1.99). Conclusions Dementia and depression are common in community-dwelling older Americans, and hospitalization is associated with these conditions. Additional research increasing understanding of the bi-directional relationship between hospitalizations, dementia, and depression, along with targeted interventions to reduce hospitalizations, are needed.

    Most people with dementia in Western societies will eventually be placed in a nursing home. This can be stressful to those with dementia and to their families. The adjustment to this new caring environment by both residents and their family caregivers and the factors that influence this are the focus of this review. A literature search of Embase, Scopus, and Medline databases of articles published in English between 1990 and 2011 using specified search terms was performed to examine this transition. The 174 titles located were screened and reference lists hand searched resulting in the 49 relevant articles included in this review. This decision and the subsequent adjustment period is a difficult time for people with dementia and their family caregivers. Admission has been linked to increased behavioral symptoms and in particular depression and agitation, decreasing cognition, frailty, and falls in people with dementia. For caregivers, guilt, depression, feelings of failure, and continuing burden but also improvement in quality of life have been variously reported. Research to determine what influences the trajectory of these different outcomes and the prevalence of positive outcomes for people with dementia is lacking. Successful transitions may be assisted by ensuring that the person with dementia has input into decision making, orientation procedures for the person with dementia and family member prior to and on admission, a "buddy" system for new arrivals, and a person-centered approach. Adjustment to admission to residential care can be difficult for people with dementia and their family caregivers. Longitudinal research examining factors influencing the adjustment can provide a basis for intervention trials to improve this transition.

    The elderly represent the fastest growing population group in France. The care management of people suffering from dementia has become an important problem. Demented patients manifest behavioral problems, depression, apathy, impairment in social activities and language skill disorders. The literature contains few studies investigating animal-assisted therapy for demented patients. However, there is a clear need for psychological assistance for this population. In the management of such behavioural problems associated with dementia, we propose to develop a dog-assisted therapy. Three qualitative case studies are analysed to specify the perceptions of the therapist regarding animal-assisted therapy. This study is a qualitative pilot study. Subjects were two female and one male patients admitted in a nursing home. They were diagnosed with severe dementia. Their mean age was 94 years. All of them agreed to attend the dog therapy activities and informed consent from their family was requested. We met these patients 15 times over nine months. The meetings always took place in the same place for 30 min, once a week. The evaluation was based on the clinical observations of the psychologist. This study revealed many psychological benefits for patients with dementia. The animal-assisted therapy had a calming effect on the patients. It could well be helpful as a communication link during therapy sessions. The dog, because of its unconditional acceptance, increases the self-esteem of the patient and contributes to a more secure environment. The patients, who rarely interacted socially, increased their interactions with the dog. In spite of the lack of normal verbal use of language, nonverbal communication continues including touching and posture. Furthermore, patients verbalized that the dog was affectionate and they could identify themselves with it. This prospective study leads up to the conclusion that pet therapy could prove to be efficient. We conducted animal

  4. The Appropriate Use of Neuroimaging in the Diagnostic Work-Up of Dementia

    2014-01-01

    Background Diagnosis of dementia is challenging and requires both ruling out potentially treatable underlying causes and ruling in a diagnosis of dementia subtype to manage patients and suitably plan for the future. Objectives This analysis sought to determine the appropriate use of neuroimaging during the diagnostic work-up of dementia, including indications for neuroimaging and comparative accuracy of alternative technologies. Data Sources A literature search was performed using Ovid MEDLINE, Ovid MEDLINE In-Process and Other Non-Indexed Citations, Ovid Embase, the Wiley Cochrane Library, and the Centre for Reviews and Dissemination database, for studies published between 2000 and 2013. Review Methods Data on diagnostic accuracy and impact on clinical decision making were abstracted from included studies. Quality of evidence was assessed using GRADE. Results The search yielded 5,374 citations and 15 studies were included. Approximately 10% of dementia cases are potentially treatable, though less than 1% reverse partially or fully. Neither prediction rules nor clinical indications reliably select the subset of patients who will likely benefit from neuroimaging. Clinical utility is highest in ambiguous cases or where dementia may be mixed, and lowest for clinically diagnosed Alzheimer disease or clinically excluded vascular dementia. There is a lack of evidence that MRI is superior to CT in detecting a vascular component to dementia. Accuracy of structural imaging is moderate to high for discriminating different types of dementia. Limitations There was significant heterogeneity in estimates of diagnostic accuracy, which often prohibited a statistical summary of findings. The quality of data reported by studies prohibited calculation of likelihood ratios in the present analysis. No studies from primary care were found; thus, generalizability beyond tertiary care settings may be limited. Conclusions A diagnosis of reversible dementia is rare. Imaging has the most

    To assess reductions of cerebral glucose metabolism in Parkinson's disease (PD) with 18F-fluorodeoxyglucose (FDG) positron emission tomography (PET), and their associations with cognitive decline. FDG-PET was performed on a cohort of 79 patients with newly diagnosed PD (mean disease duration 8 months) and 20 unrelated controls. PD participants were scanned while on their usual dopaminergic medication. Cognitive testing was performed at baseline, and after 18 months using the Cognitive Drug Research (CDR) and Cambridge Neuropsychological Test Automated Battery (CANTAB) computerised batteries, the Mini-Mental State Examination (MMSE), and the Montreal Cognitive Assessment (MoCA). We used statistical parametric mapping (SPM V.12) software to compare groups and investigate voxelwise correlations between FDG metabolism and cognitive score at baseline. Linear regression was used to evaluate how levels of cortical FDG metabolism were predictive of subsequent cognitive decline rated with the MMSE and MoCA. PD participants showed reduced glucose metabolism in the occipital and inferior parietal lobes relative to controls. Low performance on memory-based tasks was associated with reduced FDG metabolism in posterior parietal and temporal regions, while attentional performance was associated with more frontal deficits. Baseline parietal to cerebellum FDG metabolism ratios predicted MMSE (β=0.38, p=0.001) and MoCA (β=0.3, p=0.002) at 18 months controlling for baseline score. Reductions in cortical FDG metabolism were present in newly diagnosed PD, and correlated with performance on neuropsychological tests. A reduced baseline parietal metabolism is associated with risk of cognitive decline and may represent a potential biomarker for this state and the development of PD dementia.

    Many veterans of the wars in Afghanistan and Iraq have concomitant respiratory conditions and mental health conditions. We wanted to evaluate the association of mental health diagnoses with respiratory disease diagnoses among post-deployment veterans. We conducted a retrospective cohort study of all Afghanistan and Iraq War veterans who were discharged from the military or otherwise became eligible to receive Veterans Health Administration services. The primary exposure was receipt of a mental health diagnosis and the primary outcome was receipt of a respiratory diagnosis as recorded in the electronic health record. We used multivariable adjusted logistic regression to measure the associations of mental health diagnoses with respiratory diagnoses and conducted several analyses exploring the timing of the diagnoses. Among 182,338 post-deployment veterans, 14% were diagnosed with a respiratory condition, 77% of whom had a concomitant mental health diagnosis. The incidence rates were 5,363/100,000 person-years (p-y), 587/100,000 p-y, 1,450/100,000 p-y, and 233/100,000 p-y for any respiratory disease diagnosis, bronchitis, asthma, and chronic obstructive lung disease diagnoses, respectively, after the date of first Veterans Health Administration utilization. Any mental health diagnosis was associated with increased odds for any respiratory diagnosis (adjusted odds ratio 1.41, 95% confidence interval 1.37-1.46). The association of mental health diagnoses and subsequent respiratory disease diagnoses was stronger and more consistent than the converse. Many Afghanistan and Iraq War veterans are diagnosed with both respiratory and mental illnesses. Comprehensive plans that include care coordination with mental health professionals and treatments for mental illnesses may be important for many veterans with respiratory diseases.

    Cognitive reserve hypothesis predicts that intellectually demanding activities over the life course protect against dementia. We investigate if childhood school performance remains associated with dementia once education and occupational complexity are taken into account. A cohort of 440 individuals aged 75+ from the Kungsholmen Project was followed up for 9 years to detect dementia. To measure early-life contributors to reserve, we used grades at age 9-10 extracted from the school archives. Data on formal education and occupational complexity were collected at baseline and first follow-up. Dementia was ascertained through comprehensive clinical examination. Cox models estimated the relationship between life-course cognitive reserve measures and dementia. Dementia risk was elevated [hazard ratio (HR): 1.54, 95% confidence interval (CI): 1.03 to 2.29] in individuals with low early-life school grades after adjustment for formal educational attainment and occupational complexity. Secondary education was associated with a lower risk of dementia (HR: 0.72, 95% CI: 0.50 to 1.03), although the effects of post-secondary and university degrees were indistinguishable from baseline. Occupational complexity with data and things was not related to dementia. However, an association was found between high occupational complexity with people and dementia, albeit only in women (HR: 0.39, 95% CI: 0.14 to 0.99). The pattern of results remained unchanged after adjustment for genetic susceptibility, comorbidities and depressive symptoms. Low early-life school performance is associated with an elevated risk of dementia, independent of subsequent educational and occupational attainment. © The Author 2016; all rights reserved.

  9. Dementia and the gender trouble?: Theorising dementia, gendered subjectivity and embodiment.

    Science.gov (United States)

    Sandberg, Linn J

    2018-06-01

    Despite person-centred approaches increasingly focusing on looking at the person in dementia instead of the pathology, the role of gender in dementia has been little explored. This article discusses how pervasive discourses on a loss of self and dementia as abject are interwoven with a de-gendering of persons with dementia. The cultural anxiety that dementia evokes in terms of loss of bodily and cognitive control could also be linked to a failure to normatively and intelligibly express gender when living with dementia. As a way to sustain personhood for people with dementia and challenge discourses on people with dementia as 'non-people', person-centred approaches have emphasised the collaborative work of carers, relatives and persons with dementia. Often implicitly, this also involves a 're-gendering' of persons with dementia where gendered biographies and pasts are upheld and gendered embodied selfhood is maintained through, for example, dress, hair and other aspects of appearance. This re-gendering could be of great significance for people with dementia to become intelligible as persons. Still, dementia studies must further consider non-normative expressions of gender and involve feminist theorising on gender as a power asymmetry since some embodiments and selves are more likely to be sustained in dementia than others.

    To examine the possibility of diagnosing Alzheimer-type dementia, we studied this condition using the run length matrix, on head MR images of 29 Alzheimer-type dementia patients (8 men, 21 women, 78.7±6.7 years) and healthy elderly controls (10 men, 19 women, 72.3±8.7 years). The results showed that differences in GLN (gray level nonuniformity) and RLN (run length nonuniformity) were statistically significant. Furthermore, discriminant analysis based on GLN and RLN showed a rate of sensitivity of 69.0%, specificity 86.2%, and correct classification 77.6%. Although this rate of correct classification is inferior to the planimetric and volumetric methods, run length matrix is only one method of texture analysis. The results of this study indicate the possibility of MR imaging-based diagnosis of Alzheimer-type dementia with texture analysis including a run length matrix. (author)

    Intracranial stenosis is a common vascular lesion observed in Asian and other non-Caucasian stroke populations. However, its role in cognitive impairment and dementia has been under-studied. We, therefore, examined the association of intracranial stenosis with cognitive impairment, dementia and their subtypes in a memory clinic case-control study, where all subjects underwent detailed neuropsychological assessment and 3 T neuroimaging including three-dimensional time-of-flight magnetic resonance angiography. Intracranial stenosis was defined as ≥50% narrowing in any of the intracranial arteries. A total of 424 subjects were recruited of whom 97 were classified as no cognitive impairment, 107 as cognitive impairment no dementia, 70 vascular cognitive impairment no dementia, 121 Alzheimer's Disease, and 30 vascular dementia. Intracranial stenosis was associated with dementia (age/gender/education - adjusted odds ratios (OR): 4.73, 95% confidence interval (CI): 1.93-11.60) and vascular cognitive impairment no dementia (OR: 3.98, 95% CI: 1.59-9.93). These associations were independent of cardiovascular risk factors and MRI markers. However, the association with Alzheimer's Disease and vascular dementia became attenuated in the presence of white matter hyperintensities. Intracranial stenosis is associated with vascular cognitive impairment no dementia independent of MRI markers. In Alzheimer's Disease and vascular dementia, this association is mediated by cerebrovascular disease. Future studies focusing on perfusion and functional markers are needed to determine the pathophysiological mechanism(s) linking intracranial stenosis and cognition so as to identify treatment strategies.

    Depression has been reported to increase the risk of subsequently developing dementia, but the nature of this relation remains to be elucidated. Depression can be a prodrome/manifestation of dementia or an early risk factor, and the effect may differ according to depression subtypes. Our aim was to study the association between early-onset depression and different depression subtypes, and the later occurrence of dementia. We conducted a cohort study including 322 subjects with depression, recruited between 1977 and 1984. A comparison cohort (non-exposed) was recruited retrospectively, to include 322 subjects admitted at the same hospital for routine surgery (appendicectomy or cholecystectomy), at the same period as the depressed cohort. Subjects were contacted again between 2009 and 2014, to assess their dementia status. We computed the risk for dementia in subjects with early onset depression and quantified the association between different depression subtypes (namely melancholic, anxious, and psychotic) and dementia. The odds of dementia were increased by 2.90 times (95% C.I. 1.61-5.21; pdepressed cohort when compared to the surgical cohort. When the analysis was restricted to patients younger than 45 years old at baseline, the odds for dementia in the depressed cohort were also significantly higher when compared to the surgical cohort (8.53; 95% C.I. 2.40-30.16). In the multivariate Cox analysis, subjects having depression with melancholic features had an increased risk for developing dementia compared to those without melancholic features (HR=3.64; 95% C.I. 1.78-11.26; p=0.025). About 59% of the participants with depression and 53% of those non-exposed were lost during follow up. The inclusion of biological biomarkers would strengthen the results. The sample included a low number of bipolar patients. These results support depression as an early risk factor for dementia. Depression with melancholic features was found as an important risk factor for dementia

    The objective of this study was to examine the psychometric quality of the 6-Item Cognitive Impairment Test (6CIT) as a bedside screening for the detection of dementia in general hospital patients. Participants (N = 1,440) were inpatients aged ≥65 of 33 randomly selected general hospitals in Southern Germany. The 6CIT was conducted at bedside, and dementia was diagnosed according to DSM-IV. Nursing staff was asked to rate the patients' cognitive status, and previous diagnoses of dementia were extracted from medical records. Completion rates and validity statistics were calculated. Two-hundred seventy patients had dementia. Cases with delirium but no dementia were excluded. Feasibility was 97.9% and 83.3% for patients without and with dementia, respectively, and decreased from moderate (93.8%) to severe dementia (53%). The area under the curve of the 6CIT was 0.98. Sensitivity, specificity, accuracy, positive predictive value, and negative predictive value were calculated for the cutoffs 7/8 (0.96, 0.82, 0.85, 0.52, 0.99) and 10/11 (0.88, 0.95, 0.94, 0.76, 0.98). The nurse ratings and medical records information had lower validity statistics. Logistic regression analyses revealed that the 6CIT statistically significantly provided information above nurse ratings and medical records. Twenty-five and 37 additional patients were correctly classified by the 7/8 and 10/11 cutoffs, respectively. The 6CIT is a feasible and valid screening tool for the detection of dementia in older general hospital patients. The 6CIT outperformed the nurse ratings of cognitive status and dementia diagnoses from medical records, suggesting that standardized screening may have benefits with regard to case finding.

    2018-05-01

    Over 200,000 Americans diagnosed with young onset dementia (YOD), dementia diagnosed prior to age 65, are cared for by family members. This can be costly to caregivers' physical and psychological health. Some adapt well to the caregiver role and are said to be resilient. Aim/Question: This paper builds on current understanding of the concept of resilience and applies this to caregivers of partners diagnosed with YOD. Concept analysis. Resilient caregivers exhibit attributes including determination, flexibility, positive thinking, self-efficacy, resourcefulness, social support and spirituality. YOD affects caregiver's health. Much research has been done on interventions for dementia caregivers. These interventions do not necessarily meet the needs of YOD caregivers as they do not account for dynamics in the family. By recognizing what is resiliency in YOD caregivers, interventions can be developed that focus on characteristics that build these attributes. Understanding the concept of resilience related to caregiving for a partner diagnosed with YOD allows for future development, measurement, and evaluation of nursing interventions. Nursing staff are in a strategic position to provide effective interventions to enhance resilience among caregivers of YOD.

    Patients with "mild to moderate" dementia might improve with appropriate drug therapy whereas patients with "severe" dementia are generally considered to have an irreversible condition, providing acute metabolic disorders have been excluded and appropriate investigations have been performed to exclude neurological conditions that might be amenable to neurosurgery. Since it is unlikely that this type of patient will be referred to the hospital outpatient clinics, it is necessary to identify these patients in the community. For this purpose, authors have used the Abbreviated Mental Test. A comparison between two observers (nurse and doctor) has been made. Subsequently, a 6 symptoms check-list, as abbreviated form of the Crichton Royal Rating Scale for geriatric patients, was used in an open pilot study on 260 patients completing a 12 weeks treatment by dihydroergotoxine mesylate (codergocrine mesylate, Hydergine) 4.5 mg once a day. Although this was an open pilot study, it does show that it is possible to identify and treat patients with "mild to moderate" dementia in the community. A single dose formulation in the elderly has obvious advantages. In this study, compliance was excellent and 88% of the patients showed significant improvement using the suggested rating scales.

    There are few studies on validation of depression scales in the elderly in Latin America. This study aimed to assess the validity of Montgomery-Åsberg. Depression Rating Scale (MADRS) and Cornell Scale for Depression in Dementia (CSDD) in Brazilian elderly outpatients. A convenience sample of 95 outpatients was diagnosed for dementia and depression according to DSM-IV-TR, ICD-10, and PDC-dAD criteria. Receiver Operating Curves (ROC) were used to calculate the area under the curve (AUC) and to assess MADRS and CSDD cut-offs for each diagnostic criterion. Dementia was diagnosed in 71 of 95 patients. Depression was diagnosed in 35, 30, and 51 patients by ICD-10, DSM-IV, and PDC-dAD, respectively. MADRS cut-off score of 10 correctly diagnosed 67.4% and 66.3% patients as depressed according to DSM-IV and ICD-10. A cut-off of 9 correctly identified 74.7% by PDC-dAD criteria; a CSDD cut-off score of 13 best recognized depression according to DSM-IV and ICD-10. A score of 11 diagnosed depression according to PDC-dAD, while MADRS = 9 recognized depression in dementia. CSDD was more efficient in showing depression in mild than in moderate/severe dementia according to DSM-IV/ICD-10. PDC-dAD behaved nicely for any severity stage. MADRS and CSDD cut-offs of 10 and 13 were the optimal ones to diagnose depression in elderly, respectively. CSDD cut-offs are higher than those found in other countries. Other Latin American studies are needed to compare results with our study.

    Patient data in clinical research often includes large amounts of structured information, such as neuroimaging data, neuropsychological test results, and demographic variables. Given the various sources of information, we can develop computerized methods that can be a great help to clinicians to discover hidden patterns in the data. The computerized methods often employ data mining and machine learning algorithms, lending themselves as the computer-aided diagnosis (CAD) tool that assists clinicians in making diagnostic decisions. In this chapter, we review state-of-the-art methods used in dementia research, and briefly introduce some recently proposed algorithms subsequently.

    Full Text Available Clinicopathological studies are important in determining the brain lesions underlying dementia. Although almost 60% of individuals with dementia live in developing countries, few clinicopathological studies focus on these individuals. We investigated the frequency of neurodegenerative and vascular-related neuropathological lesions in 1,092 Brazilian admixed older adults, their correlation with cognitive and neuropsychiatric symptoms, and the accuracy of dementia subtype diagnosis.In this cross-sectional study, we describe clinical and neuropathological variables related to cognitive impairment in 1,092 participants (mean age = 74 y, 49% male, 69% white, and mean education = 4 y. Cognitive function was investigated using the Clinical Dementia Rating (CDR and the Informant Questionnaire on Cognitive Decline in the Elderly (IQCODE; neuropsychiatric symptoms were evaluated using the Neuropsychiatric Inventory (NPI. Associations between neuropathological lesions and cognitive impairment were investigated using ordinal logistic regression. We developed a neuropathological comorbidity (NPC score and compared it to CDR, IQCODE, and NPI scores. We also described and compared the frequency of neuropathological diagnosis to clinical diagnosis of dementia subtype. Forty-four percent of the sample met criteria for neuropathological diagnosis. Among these participants, 50% had neuropathological diagnoses of Alzheimer disease (AD, and 35% of vascular dementia (VaD. Neurofibrillary tangles (NFTs, hippocampal sclerosis, lacunar infarcts, hyaline atherosclerosis, siderocalcinosis, and Lewy body disease were independently associated with cognitive impairment. Higher NPC scores were associated with worse scores in the CDR sum of boxes (β = 1.33, 95% CI 1.20-1.46, IQCODE (β = 0.14, 95% CI 0.13-0.16, and NPI (β = 1.74, 95% CI = 1.33-2.16.

    Using magnetization transfer (MT) imaging, we studied the underlying pathological conditions of periventricular hyperintense (PVH) white matter changes seen on T2-weighted MR images of patients with multi-infarct dementia. Twenty-two patients with multiple lacunar infarcts and PVH lesions, including 11 with dementia (diagnosed as multi-infarct dementia) and 11 without dementia, and 10 control subjects (with multiple lacunes, but no PVH lesion) were studied using the MT technique. MT ratios (MTRs) were calculated for PVH lesions (normal-appearing frontal white matter in controls) and the genu of the corpus callosum. Signal intensities on T2-weighted images in PVH lesions of patients were significantly higher than those in normal-appearing white matter of controls, while there were no significant differences in signal intensity in the genu of the corpus callosum among the dementia, non-dementia and control groups. However, MTRs in patients with PVH lesions were significantly lower than those in controls, and MTRs in demented patients were significantly lower than those in non-demented patients. Moreover, MTRs in the genu of the corpus callosum of demented patients were significantly lower than in those in non-demented patients and controls. MTRs in PVH lesions and the genu of the corpus callosum significantly correlated with Hasegawa's dementia scale score. These results suggest that there is some difference in histopathologic changes of PVH lesions between demented and non-demented patients and that the pathological substrate in the corpus callosum may play a role in inducing cognitive decline. Studies with MT imaging may allow the characterization of different pathological conditions that cannot be visualized by conventional MRI. (author)

    Abstract Pneumonia is a frequent complication in dementia patients and is associated with high mortality rates. The aim of this retrospective cohort study was to determine whether traditional Chinese medicine (TCM) therapy can decrease pneumonia risk in dementia patients. The cohort dataset was obtained from the Longitudinal Health Insurance Database 2005, a sublibrary of the National Health Insurance Research Database, containing all medical data of 1 million beneficiaries, randomly selected from the all Insurers in year 2005. Newly diagnosed dementia patients (n = 9712) without pneumonia were analyzed from January 1997 to December 2003. After matching by sex, age, urban level, Charlson comorbidity index, insured amount, and comorbidities, 1376 pairs (1:1) of TCM and non-TCM users were acquired. Every dementia patient was individually recorded from 1997 to 2012 to identify pneumonia incidence (onset after 3 months of dementia diagnosis). Demographic characteristics, Charlson comorbidity index, comorbidities, behavioral and psychological symptoms of dementia, and psychotropic drugs were also investigated. Cox proportional regression was used to compute hazard ratios and 95% confidence intervals (CIs) after adjustment for the above-mentioned variables. There were 419 (30.5%) and 762 (55.4%) pneumonia cases in the TCM and non-TCM cohorts during a mean follow-up period of 7.6 years. The adjusted hazard ratios (95% CI) for pneumonia admission was 0.62 (0.55–0.70) for the TCM group. Patients who received TCM therapy at higher cumulative doses or for longer periods experienced increased protection from pneumonia admission. Ma-Xing-Gan-Shi-Tang, Yin-Qiao-San, and Xiao-Qing-Long-Tang might represent possible formulae reducing the incidence of pneumonia. TCM might be associated with a lower risk of pneumonia in dementia patients. PMID:27631269

    Objective: While psychology is accepted as a necessary component of the dementia diagnostics, the extended clinical diagnostics with neuroimaging is differently estimated. The goal of the study is the quantification of the individual contribution of the two different methods. Methods: Of 100 patient the diagnosis of entrance, the neurological, the psychological, and the final clinical diagnosis were documented. For both imaging and psychology the sensitivity, specificity, and the positive predictive value were computed. The diagnostic of each method was determined from the change of the final in relation to the initial clinical diagnosis. The neuroradiological investigation took place with MRI, the psychological examination used both usual power and special speed tests. Results: The extended clinical diagnostics led for 26% of the patients to the change of the clinical diagnosis. Imaging and psychology supplied different own but supplementing contributions. In the case of annihilation imaging contributed with 73.3%, psychology with 54.1% to the diagnosis of a neurodegenerative dementia, whereas the contributions to the diagnosis of a vascular dementia were 83.3% and 70.8%, respectively. However psychology diagnosed and quantified the dementia. The contribution of neuroimaging consisted in the differential diagnosis of the dementias organic causes of symptomatic clementias and vascular encephalopathy without dementia but with consequences for a secondary prophylaxis were additional information also. Conclusion: Psychology improves the diagnostic accuracy of dementias. Neuroimaging improves the differential diagnosis of dementias and supplies additional clinically relevant findings. In the qualified diagnostics and differential diagnostics of the dementias both methods are indispensable. (orig.) [de

    Introduction: Neuroimaging plays an essential supportive role in the diagnosis of dementia, assisting in establishing the dementia subtype(s). This has significant value in both treatment and care decisions and has important implications for prognosis. This study aims to explore the development and nature of neuroimaging protocols currently used in the assessment of dementia and Alzheimer's disease (AD). Methods: An online questionnaire was designed and distributed to lead radiography personnel working in computed tomography (CT), magnetic resonance imaging (MRI) and positron emission tomography (PET) departments (n = 94) in both hospital-based and out-patient imaging centres in the Republic of Ireland. Results: Response rates for each modality ranged from 42 to 44%. CT, MRI, and PET were used to specifically diagnose dementia or AD by 43%, 40% and 50% of responding centres respectively. Of these, dementia-specific neuroimaging protocols were utilised in 33%, 50% and 100% of CT, MRI and PET centres respectively, with the remainder using either standard or other non-specific protocols. Both radiologists and clinical specialist radiographers participated in the development of the majority of protocols. The Royal College of Radiologists (RCR) guidelines were most commonly referenced as informing protocol development, however, none of the MRI respondents were able to identify any guidelines used to inform MR protocol development. Conclusion: Currently there is no consensus in Ireland on optimal dementia/AD neuroimaging protocols, particularly for PET and MRI. Similarly the use of validated and published guidelines to inform protocols is not universal. - Highlights: • We examined the nature of neuroimaging protocols for dementia and Alzheimer's disease in Ireland. • Dementia or Alzheimer's disease-specific protocols were used by between 33 and 100% of centres depending on modality. • Stated dementia-specific protocols were identical for CT whereas

    Mild cognitive impairment (MCI) is considered an intermediate stage between normal aging and dementia. It is diagnosed in the presence of subjective cognitive decline and objective cognitive impairment without significant functional impairment, although there are no standard operationalizations for each of these criteria. The objective of this study is to determine which operationalization of the MCI criteria is most accurate at predicting dementia. Six-year longitudinal study, part of the Sydney Memory and Ageing Study. Community-based. 873 community-dwelling dementia-free adults between 70 and 90 years of age. Persons from a non-English speaking background were excluded. Seven different operationalizations for subjective cognitive decline and eight measures of objective cognitive impairment (resulting in 56 different MCI operational algorithms) were applied. The accuracy of each algorithm to predict progression to dementia over 6 years was examined for 618 individuals. Baseline MCI prevalence varied between 0.4% and 30.2% and dementia conversion between 15.9% and 61.9% across different algorithms. The predictive accuracy for progression to dementia was poor. The highest accuracy was achieved based on objective cognitive impairment alone. Inclusion of subjective cognitive decline or mild functional impairment did not improve dementia prediction accuracy. Not MCI, but objective cognitive impairment alone, is the best predictor for progression to dementia in a community sample. Nevertheless, clinical assessment procedures need to be refined to improve the identification of pre-dementia individuals. Copyright © 2016 American Association for Geriatric Psychiatry.

    Although early diagnosis has been hypothesized to benefit both patients and caregivers, until now studies evaluating the effect of early dementia diagnosis are lacking. To investigate the influence of early specialist referral for dementia on the risk of institutionalization and functional decline in Activity of Daily Living (ADL). Incident dementia cases were screened in a prospective population-based cohort, the Three-City Study, and initial specialist consultation for cognitive complaint was assessed at dementia diagnosis. Proportional hazard regression and illness-death models were used to test the association between specialist referral and, respectively, institutionalization and functional decline. Only one third of the incident individuals with dementia had consulted a specialist for cognitive problems early (36%). After adjustment on potential confounders (including cognitive and functional decline) and competing risk of death, participants who had consulted a specialist early in the disease course presented a higher rate of being institutionalized than those who did not (Hazard Ratio = 2.00, 95% Confidence Interval (CI): 1.09- 3.64). But early specialist referral was not associated with further functional decline (HR = 1.09, 95% CI: 0.71- 1.67). Early specialist referral in dementia is associated with increased risk of institutionalization but not with functional decline in ADL. These findings suggest that early care referral in dementia may be a marker of concern for patients and/or caregivers; subsequent medical and social care could be suboptimal or inappropriate to allow patients to stay longer at home.

Validated biomarkers which reflect the pathology and disease progression are essential for diagnosis...... and are important when developing new therapies. Today, the core protein biomarkers amyloid-β42, total tau and phosphorylated tau in the cerebrospinal fluid (CSF) are used to diagnose Alzheimer's disease (AD), because these biomarkers have shown to reflect the underlying amyloid and tau pathology. However......, the biomarkers have proved insufficient predictors of dementias with a different pathology, e.g. frontotemporal dementia (FTD); furthermore, the biomarkers are not useful for early AD diagnosis.

    Current clinical classifications do not contain specific diagnostic categories for patients with senile dementia of the Lewy body type (SDLT), recently proposed as the second commonest neuropathological cause of dementia in the elderly. This study determines how existing clinical diagnosis systems label SDLT patients and suggests how such patients may be identified. A range of clinical diagnostic criteria for dementia were applied to case notes of autopsy-confirmed SDLT (n = 20), dementia of Alzheimer type (DAT; n = 21) and multi-infarct dementia (MID; n = 9) patients who had received psychogeriatric assessment. The predictive validity of each set of clinical criteria was calculated against the external criterion of neuropathological diagnosis. Many SDLT patients erroneously met criteria for MID (35% with Hachinski scores > or = 7) or for DAT (15% by NINCDS 'probable AD', 35% by DSM-III-R DAT and 50% by NINCDS 'possible AD'). Up to 85% of SDLT cases could be correctly identified using recently published specific criteria. SDLT usually has a discernible clinical syndrome and existing clinical classifications may need revision to diagnose correctly such patients.

    Due to a significant overlap of the two syndromes, differentiation of degenerative dementia of the Alzheimer-type from vascular dementia may be difficult even when imaging studies are available. White matter changes occur in many patients suffering from Alzheimer's disease. Little is known about the impact of white matter changes on the course and clinical presentation of Alzheimer's disease. High sensitivity of MRI in the detection of white matter alterations may account for over-diagnosing vascular dementia. The clinical significance of white matter alterations in dementia is still a matter of debate. The article reviews current concepts about the role of white matter alterations in dementia. (orig.)

    Full Text Available Background: Alzheimer dementia (AD and vascular dementia (VD are the most common causes of dementia in the elderly. Depression is an important co-morbid disorder in these diseases, which is often challenging to recognize. We investigated the prevalence of depression in patients with AD and VD and estimated the influence of depression on the health-related quality of life (HrQoL in these patients. Materials and Methods: We evaluated prevalence of depression in consecutively recruited patients with AD or VD (n= 98. Depression was diagnosed according to criteria of the Diagnostic and Statistical Manual of Mental Disorders (DSM-IV and scored using the Geriatric Depression Scale. The EuroQol (EQ-5D and visual analogue scale was applied to evaluate HrQoL. The severity of cognitive impairment was measured by the Mini-Mental State Examination (MMSE. Multiple regression analysis was used to identify factors predicting severity of depression. Results: The prevalence of depression in AD/VD was 87%. In comparison to the general population, HrQoL measured on the visual analogue scale was reduced by 54% in patients with AD/VD. In the dimension "anxiety/depression" of the EQ-5D, 81% of patients with AD/VD had moderate or severe problems. Depression showed significant association with reduced HrQoL (P<0.01. Independent predictors of more severe depression were older age, male gender, better MMSE scores and being not married. Conclusions: Depression is a prevalent psychiatric co-morbidity in patients with AD/VD, which is often under-diagnosed being masked by cognitive impairment. Depression is a predictor of reduced HrQoL in elder people with AD/VD. Therefore, they should be screened for presence of depressive symptoms and receive adequate antidepressant treatment.

    2003-03-01

    Night sweats are a common outpatient complaint, yet literature on the subject is scarce. Tuberculosis and lymphoma are diseases in which night sweats are a dominant symptom, but these are infrequently found to be the cause of night sweats in modern practice. While these diseases remain important diagnostic considerations in patients with night sweats, other diagnoses to consider include human immunodeficiency virus, gastroesophageal reflux disease, obstructive sleep apnea, hyperthyroidism, hypoglycemia, and several less common diseases. Antihypertensives, antipyretics, other medications, and drugs of abuse such as alcohol and heroin may cause night sweats. Serious causes of night sweats can be excluded with a thorough history, physical examination, and directed laboratory and radiographic studies. If a history and physical do not reveal a possible diagnosis, physicians should consider a purified protein derivative, complete blood count, human immunodeficiency virus test, thyroid-stimulating hormone test, erythrocyte sedimentation rate evaluation, chest radiograph, and possibly chest and abdominal computed tomographic scans and bone marrow biopsy.

    The aim of our study is to describe the types of dementia found in a series of patients and to estimate the level of agreement between the clinical diagnosis and post-mortem diagnosis. We conducted a descriptive analysis of the prevalence of the types of dementia found in our series and we established the level of concordance between the clinical and the post-mortem diagnoses. The diagnosis was made based on current diagnostic criteria. 114 cases were included. The most common clinical diagnoses both at a clinical and autopsy level were Alzheimer disease and mixed dementia but the prevalence was quite different. While at a clinical level, prevalence was 39% for Alzheimer disease and 18% for mixed dementia, in the autopsy level, prevalence was 22% and 34%, respectively. The agreement between the clinical and the autopsy diagnoses was 62% (95% CI 53-72%). Almost a third of our patients were not correctly diagnosed in vivo. The most common mistake was the underdiagnosis of cerebrovascular pathology. Copyright © 2016 Sociedad Española de Neurología. Publicado por Elsevier España, S.L.U. All rights reserved.

    Traumatic brain injury (TBI) is common in both veteran and civilian populations. Prior studies have linked moderate and severe TBI with increased dementia risk, but the association between dementia and mild TBI, particularly mild TBI without loss of consciousness (LOC), remains unclear. To examine the association between TBI severity, LOC, and dementia diagnosis in veterans. This cohort study of all patients diagnosed with a TBI in the Veterans Health Administration health care system from October 1, 2001, to September 30, 2014, and a propensity-matched comparison group. Patients with dementia at baseline were excluded. Researchers identified TBIs through the Comprehensive TBI Evaluation database, which is restricted to Iraq and Afghanistan veterans, and the National Patient Care Database, which includes veterans of all eras. The severity of each TBI was based on the most severe injury recorded and classified as mild without LOC, mild with LOC, mild with LOC status unknown, or moderate or severe using Department of Defense or Defense and Veterans Brain Injury Center criteria. International Classification of Diseases, Ninth Revision codes were used to identify dementia diagnoses during follow-up and medical and psychiatric comorbidities in the 2 years prior to the index date. Dementia diagnosis in veterans who had experienced TBI with or without LOC and control participants without TBI exposure. The study included 178 779 patients diagnosed with a TBI in the Veterans Health Administration health care system and 178 779 patients in a propensity-matched comparison group. Veterans had a mean (SD) age of nearly 49.5 (18.2) years at baseline; 33 250 (9.3%) were women, and 259 136 (72.5%) were non-Hispanic white individuals. Differences between veterans with and without TBI were small. A total of 4698 veterans (2.6%) without TBI developed dementia compared with 10 835 (6.1%) of those with TBI. After adjustment for demographics and medical and psychiatric

    2017-07-01

    This essay will briefly sketch historical changes in the framing of dementia since the late nineteenth century. In broad terms, this period has seen a shift from viewing dementia as a pathological variant of normal aging to viewing it as a distinct disease. Although this broad reframing of dementia was clearly positive in raising awareness and funding for research, it had some negative aspects that should be considered. Caregiving came to seem less important than research aimed at a cure, and the stigma surrounding dementia has, if anything, increased. © 2017 American Medical Association. All Rights Reserved.

    The aim of this paper is to argue for the utility of a relational model of disability, as a way of conceptualizing dementia. We explore whether dementia should be considered as a disability, and whether people with dementia might consider themselves as disabled people. We review examples of, and issues raised by, the political activism of people with dementia. We consider how language constructs dementia negatively. We discuss how the environment influences the experience of dementia. In conclusion, we show that a relational model of dementia lays the basis for a human rights approach to the condition, based on collaborative partnerships between people with dementia and people from other disability communities.

    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.

    2017-07-01

    An interpretive analysis of 38 state dementia plans compares similarities and differences in diagnostic framing (problem identification/trends/issues), prognosis framing (addressing the problem), and motivational framing (calls for action) across plans. In framing diagnosis, only 6 plans used dementia alone in their titles. In framing prognosis and the subsequent call to action, state plans were consistent in their dire prognostications about the progressive and fatal consequences of the disease with a primary focus on the cost. Motivational language mirrored that of the Alzheimer's Disease (AD) Movement, from raising awareness to using inflammatory words to incite action. The language used set up the frame for clinical interventions that may not distinguish between types of dementia and could undercut the provision of person-centered care, shifts the victimization focus from persons with AD to caregivers and ultimately the state, and may subintentionally reflect cultural biases.

    There are an increasing number of people with dementia living in their own home for longer, often supported by a family member. The symptoms of dementia can affect an individual's nutritional status, which can lead to a reduced quality of life for the person with dementia and their family members. A scoping review was conducted from July 2016 until September 2016, using a recognised framework, to explore what is currently known, and identify any gaps in the research regarding the nutritional care of people living with dementia at home. This included any interventions that may have been trialled or implemented, and the views of those living with dementia, carers and clinicians. Six electronic databases were searched from inception to July 2016. A review team was involved in screening and data extraction for selected articles. Published qualitative and quantitative studies were included that explored the nutritional care of people living with dementia at home. Methods included data extraction and conventional content analysis. Stakeholders were involved in the development of final categories. Following screening, 61 studies reported in 63 articles were included. Most studies were cross-sectional (n = 24), cohort (n = 15) or qualitative (n = 9). Only three were randomised controlled trials. Three overarching categories represented the results: Timely identification of nutritional risk and subsequent regular monitoring of nutritional status, multi-component tailored interventions and the influence of the care-giving dyad on nutritional status. Many studies identify people living at home with dementia as a vulnerable group prone to malnutrition; however, a lack of interventions exists to address the increased risk. There is a lack of research exploring the role of home care providers and healthcare professionals in the provision of nutritional care. Further research is required to explore how the emotional aspect of the care-giving dyad influences nutritional care

  10. Transcranial magnetic stimulation and transcranial direct current stimulation: treatments for cognitive and neuropsychiatric symptoms in the neurodegenerative dementias?

    Science.gov (United States)

    2014-01-01

    Introduction Two methods of non-invasive brain stimulation, transcranial magnetic stimulation (TMS) and transcranial direct current stimulation (tDCS), have demonstrable positive effects on cognition and can ameliorate neuropsychiatric symptoms such as depression. Less is known about the efficacy of these approaches in common neurodegenerative diseases. In this review, we evaluate the effects of TMS and tDCS upon cognitive and neuropsychiatric symptoms in the major dementias, including Alzheimer’s disease (AD), vascular dementia (VaD), dementia with Lewy bodies (DLB), Parkinson’s disease with dementia (PDD), and frontotemporal dementia (FTD), as well as the potential pre-dementia states of Mild Cognitive Impairment (MCI) and Parkinson’s disease (PD). Methods PubMed (until 7 February 2014) and PsycINFO (from 1967 to January Week 3 2014) databases were searched in a semi-systematic manner in order to identify relevant treatment studies. A total of 762 studies were identified and 32 studies (18 in the dementias and 14 in PD populations) were included. Results No studies were identified in patients with PDD, FTD or VaD. Of the dementias, 13 studies were conducted in patients with AD, one in DLB, and four in MCI. A total of 16 of the 18 studies showed improvements in at least one cognitive or neuropsychiatric outcome measure. Cognitive or neuropsychiatric improvements were observed in 12 of the 14 studies conducted in patients with PD. Conclusions Both TMS and tDCS may have potential as interventions for the treatment of symptoms associated with dementia and PD. These results are promising; however, available data were limited, particularly within VaD, PDD and FTD, and major challenges exist in order to maximise the efficacy and clinical utility of both techniques. In particular, stimulation parameters vary considerably between studies and are likely to subsequently impact upon treatment efficacy. PMID:25478032

    The impact of dementia and Alzheimer's disease extends far beyond the healthcare needs of the person with dementia. As the disease progresses, individuals with dementia often require ongoing formal or informal care for their basic daily routine because of behavior changes and continuing loss of cognitive function. Most of the care for people with dementia takes place at home, and the unpaid, informal caregivers are often spouses or other relatives. Providing long-term informal care at home for someone with dementia is psychologically, physically, and financially draining. The tragedy described in this case elucidates the far-reaching societal impact of dementia care and the implicit health policy considerations. In 2007, a 91-year-old Japanese man with dementia was in the care of his wife when he wandered from home, was hit by a train, and died, immediately affecting the Central Japan Railway Company operations and, subsequently, legal practice as well as Japanese elder care policy. The railway sued the man's wife and son for negligence and lost revenue, winning both trials at the local and district courts. This ruling shocked families and caregivers in Japan, where care for elderly parents traditionally falls on the oldest son, and brought attention to the complex issues related to dementia care. A decade later, we revisit this case to provoke a renewed dialogue about the matrix of responsibilities and liabilities associated with caregiving; to illuminate the unmet needs of the person with dementia, as well as his or her informal caregivers; and the financial implications related to long-term care policy. We close with 2 practical suggestions which preserve the dignity of the individual and provide reassurance for caregivers.

    Military veterans diagnosed with dementia compose a large portion of our population. Often ignored are their caregivers and their plight as well as the availability, quality, and accessibility of health care for this demographic. The purpose of this systematic literature review is three fold: to identify opportunities available to increase public awareness on the subject; to identify areas of improvement in the level of care and quality of life for our nation's veterans; and to identify if adequate resources are available to veterans with dementia and their caregivers. The authors conducted systematic searches of three databases: PubMed via The National Center for Biotechnology Information, the Cumulative Index of Nursing and Allied Health Literature (CINAHL) Complete via Ebson B. Stephens Company (EBSCO Host), and Google. Data were collected regarding providing care to veterans who are suffering from dementia or Alzheimer's disease and their caregivers between 2008 and June 2016. Search results were filtered by date range, full text, English language, Boolean operators, and academic journals (n = 14). The review confirmed there are many facilitators and barriers in the coordination of care offered to veterans with dementia. Facilitators of quality care include veteran's expectations, family support, program development, and the availability of services. These positive aspects are aided by several community-based support services, new technology, and preventative care. Barriers are caregiver expectations, coordination of care, providers, and informal and formal costs. These negative facets are due to lack of educational resources, an increased veteran population diagnosed with dementia, limited knowledge of resources, and limited medical service in rural areas. Overall, there are a number of community programs that want to, and can, help veterans with dementia. There are also a number of ways to help veterans with dementia cope with their issues, which include

    Dementia is a large and growing problem but is often not diagnosed in its earlier stages. Screening and earlier treatment could reduce the burden of suffering of this syndrome. To review the evidence of benefits and harms of screening for and earlier treatment of dementia. MEDLINE, PsycINFO, EMBASE, the Cochrane Library, experts, and bibliographies of reviews. The authors developed eight key questions representing a logical chain between screening and improved health outcomes, along with eligibility criteria for admissible evidence for each question. Admissible evidence was obtained by searching the data sources. Two reviewers abstracted relevant information using standardized abstraction forms and graded article quality according to U.S. Preventive Services Task Force criteria. No randomized, controlled trial of screening for dementia has been completed. Brief screening tools can detect some persons with early dementia (positive predictive value caregiver interventions may delay nursing home placement of patients who have caregivers, the relevance of this finding for persons who do not yet have caregivers is uncertain. Other potential benefits and harms of screening have not been studied. Screening tests can detect undiagnosed dementia. In persons with mild to moderate clinically detected Alzheimer disease, cholinesterase inhibitors are somewhat effective in slowing cognitive decline. The effect of cholinesterase inhibitors or other treatments on persons with dementia detected by screening is uncertain.

    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.)

    Chronic periodontitis and gingivitis are associated with various diseases; however, their impact on dementia is yet to be elucidated. This study is aimed at investigating the association between chronic periodontitis and gingivitis, and the risk of developing dementia. A total of 2,207 patients, with newly diagnosed chronic periodontitis and gingivitis between January 1, 2000 and December 31, 2000, were selected from the National Health Insurance Research Database of Taiwan, along with 6,621 controls matched for sex and age. After adjusting for confounding factors, Cox proportional hazards analysis was used to compare the risk of developing dementia during the 10-year follow-up period. Of the study subjects, 25 (1.13%) developed dementia compared to 61 (0.92%) in the control group. Cox proportional hazards regression analysis revealed that the study subjects were more likely to develop dementia (hazard ratio (HR) 2.085, 95% CI 1.552-4.156, p gingivitis have a higher risk of developing dementia. However, further studies on other large or national data sets are required to support the current findings. © 2016 S. Karger AG, Basel.

    Full Text Available Increasing evidence supports that playing a musical instrument may benefit cognitive development and health at young ages. Whether playing an instrument provides protection against dementia has not been established. In a population-based cotwin control study, we examined the association between playing a musical instrument and whether or not the twins developed dementia or cognitive impairment. Participation in playing an instrument was taken from informant-based reports of twins’ leisure activities. Dementia diagnoses were based on a complete clinical workup using standard diagnostic criteria. Among 157 twin pairs discordant for dementia and cognitive impairment, 27 pairs were discordant for playing an instrument. Controlling for sex, education, and physical activity, playing a musical instrument was significantly associated with less likelihood of dementia and cognitive impairment (odds ratio [OR] = 0.36 [95% confidence interval 0.13–0.99]. These findings support further consideration of music as a modifiable protective factor against dementia and cognitive impairment.

  18. Diagnosing suffering: a perspective.

    Cassell, E J

    1999-10-05

    The alleviation of suffering is crucial in all of medicine, especially in the care of the dying. Suffering cannot be treated unless it is recognized and diagnosed. Suffering involves some symptom or process that threatens the patient because of fear, the meaning of the symptom, and concerns about the future. The meanings and the fear are personal and individual, so that even if two patients have the same symptoms, their suffering would be different. The complex techniques and methods that physicians usually use to make a diagnosis, however, are aimed at the body rather than the person. The diagnosis of suffering is therefore often missed, even in severe illness and even when it stares physicians in the face. A high index of suspicion must be maintained in the presence of serious disease, and patients must be directly questioned. Concerns over the discomfort of listening to patients' severe distress are usually more than offset by the gratification that follows the intervention. Often, questioning and attentive listening, which take little time, are in themselves ameliorative. The information on which the assessment of suffering is based is subjective; this may pose difficulties for physicians, who tend to value objective findings more highly and see a conflict between the two kinds of information. Recent advances in understanding how physicians increase the utility of information and make inferences allow one to reliably use the subjective information on which the diagnosis and treatment of suffering depend. Knowing patients as individual persons well enough to understand the origin of their suffering and ultimately its best treatment requires methods of empathic attentiveness and nondiscursive thinking that can be learned and taught. The relief of suffering depends on physicians acquiring these skills.

Aging is associated with a large increase in the prevalence and incidence of degenerative (Alzheimer’s disease and vascular dementia, leading to a devastating loss of autonomy. In view of the increasing longevity of populations worldwide, prevention of dementia has turned into a major public health challenge. In the past decade, several vascular risk factors have been found to be associated with vascular dementia but also Alzheimer’s disease. Some longitudinal studies, have found significant associations between hypertension, diabetus mellitus, and metabolic syndrome, assessed at middle age, and dementia. Studies assessing the link between hypercholesterolemia, atrial fibrillation, smoking, and dementia have given more conflicting results. Furthermore, some studies have highlighted the possible protective effect of antihypertensive therapy on cognition and some trials are evaluating the effects of statins and treatments for insulin resistance. Vascular risk factors and their treatments are a promising avenue of research for prevention of dementia, and further long-term, placebo-controlled, randomized studies, need to be performed.Keywords: dementia, hypertension, diabetus mellitus, hypercholesterolemia, metabolic syndrome

    2017-04-01

    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.

  2. Enteral Nutrition in Dementia: A Systematic Review

    Full Text Available The aim of this systematic review is to evaluate the role of enteral nutrition in dementia. The prevalence of dementia is predicted to rise worldwide partly due to an aging population. People with dementia may experience both cognitive and physical complications that impact on their nutritional intake. Malnutrition and weight loss in dementia correlates with cognitive decline and the progress of the disease. An intervention for long term eating difficulties is the provision of enteral nutrition through a Percutaneous Endoscopic Gastrostomy tube to improve both nutritional parameters and quality of life. Enteral nutrition in dementia has traditionally been discouraged, although further understanding of physical, nutritional and quality of life outcomes are required. The following electronic databases were searched: EBSCO Host, MEDLINE, PubMed, Cochrane Database of Systematic Reviews and Google Scholar for publications from 1st January 2008 and up to and including 1st January 2014. Inclusion criteria included the following outcomes: mortality, aspiration pneumonia, pressure sores, nutritional parameters and quality of life. Each study included separate analysis for patients with a diagnosis of dementia and/or neurological disease. Retrospective and prospective observational studies were included. No differences in mortality were found for patients with dementia, without dementia or other neurological disorders. Risk factors for poor survival included decreased or decreasing serum albumin levels, increasing age or over 80 years and male gender. Evidence regarding pneumonia was limited, although did not impact on mortality. No studies explored pressure sores or quality of life.

  7. Depression and Risk of Developing Dementia

    2012-01-01

    Depression is highly common throughout the life course and dementia is common in late life. The literature suggests an association between depression and dementia, and growing evidence implies that timing of depression may be important to defining the nature of the association. In particular, earlier-life depression or depressive symptoms consistently have been shown to be associated with a 2-fold or greater increase in risk of dementia. In contrast, studies of late-life depression have been more conflicting but the majority support an association; yet, the nature of this association is unclear (e.g., if depression is a prodrome or consequence or risk factor for dementia). The likely biological mechanisms linking depression to dementia include vascular disease, alterations in glucocorticoid steroids and hippocampal atrophy, increased deposition of β-amyloid plaques, inflammatory changes, and deficits of nerve growth factors. Treatment strategies for depression might intervene on these pathways and in turn may alter risk for dementia. Given the projected increase of dementia in the coming decades, it is critically important that we understand whether treatment for depression alone or combined with other regimens improves cognition. In this review, we summarize and analyze current evidence for late-life and earlier-life depression and their relationship to dementia, discuss the primary underlying mechanisms and implications for treatment.

    What are the effects of experience on subsequent learning? We explored the effects of language-specific word order knowledge on the acquisition of sequential conditional information. Korean and English adults were engaged in a sequence learning task involving three different sets of stimuli: auditory linguistic (nonsense syllables), visual non-linguistic (nonsense shapes), and auditory non-linguistic (pure tones). The forward and backward probabilities between adjacent elements generated two equally probable and orthogonal perceptual parses of the elements, such that any significant preference at test must be due to either general cognitive biases, or prior language-induced biases. We found that language modulated parsing preferences with the linguistic stimuli only. Intriguingly, these preferences are congruent with the dominant word order patterns of each language, as corroborated by corpus analyses, and are driven by probabilistic preferences. Furthermore, although the Korean individuals had received extensive formal explicit training in English and lived in an English-speaking environment, they exhibited statistical learning biases congruent with their native language. Our findings suggest that mechanisms of statistical sequential learning are implicated in language across the lifespan, and experience with language may affect cognitive processes and later learning.

    The vision for dementia-friendly communities is challenged by limited public awareness and stigma about dementia. The study aim was to elicit stakeholder priorities for the message content of an education program to improve dementia awareness among youth; specifically, what do children need to know about dementia? A qualitative inquiry using interviews and focus groups was used. Purposive sampling achieved maximum variation in dementia experience and participant characteristics. Focus groups with Scouts in the community aged 9-12 years old (n = 22) used innovative techniques to explore children's attitudes towards people with dementia. Participants with personal experience of dementia were five people with early-stage dementia; 12 adult primary carers; four non-primary carers; and six grandchildren of a person with dementia. They were asked what is important for children to understand about dementia and what attitudes they may like an education program to confer. Content analysis was performed using NVivo10. Strong themes to emerge were that children need to know the whole truth about dementia; that individuals with dementia are "still people," that it is "not the fault" of the person with dementia; and that dementia is different and typically unpredictable for everyone. Discussions also indicated a need to educate children about ways to relate to a person with dementia, and to appreciate "positives" within a relationship. Children are our future citizens. Developing an education program for children with this message content may be fundamental to de-stigmatizing dementia and laying the foundation to dementia-friendly communities.

    Emerging studies have implicated air pollution in the neurodegenerative processes. Less is known about the influence of air pollution, especially at the relatively low levels, on developing dementia. We conducted a population-based cohort study in Ontario, Canada, where the concentrations of pollutants are among the lowest in the world, to assess whether air pollution exposure is associated with incident dementia. The study population comprised all Ontario residents who, on 1 April 2001, were 55-85years old, Canadian-born, and free of physician-diagnosed dementia (~2.1 million individuals). Follow-up extended until 2013. We used population-based health administrative databases with a validated algorithm to ascertain incident diagnosis of dementia as well as prevalent cases. Using satellite observations, land-use regression model, and an optimal interpolation method, we derived long-term average exposure to fine particulate matter (≤2.5μm in diameter) (PM 2.5 ), nitrogen dioxide (NO 2 ), and ozone (O 3 ), respectively at the subjects' historical residences based on a population-based registry. We used multilevel spatial random-effects Cox proportional hazards models, adjusting for individual and contextual factors, such as diabetes, brain injury, and neighborhood income. We conducted various sensitivity analyses, such as lagging exposure up to 10years and considering a negative control outcome for which no (or weaker) association with air pollution is expected. We identified 257,816 incident cases of dementia in 2001-2013. We found a positive association between PM 2.5 and dementia incidence, with a hazard ratio (HR) of 1.04 (95% confidence interval (CI): 1.03-1.05) for every interquartile-range increase in exposure to PM 2.5 . Similarly, NO 2 was associated with increased incidence of dementia (HR=1.10; 95% CI: 1.08-1.12). No association was found for O 3 . These associations were robust to all sensitivity analyses examined. These estimates translate to 6.1% of

    Ascertainment bias (AB) indicates a bias of an evaluation centre in estimating the prevalence/incidence of a disease due to the specific expertise of the centre. The aim of our study was to evaluate classification of different types of dementia in new cases appearing in secondary and tertiary centres, in order to evidence possible occurrence of AB in the various (secondary to tertiary) dementia centres. To assess the mechanism of AB, the rates of new cases of the different forms of dementia reported by different centres were compared. The centres involved in the study were 11 hospital-based centres including a tertiary centre, located in the University Department of Clinical Neurology. The tertiary centre is endowed with state-of-the-art diagnostic facilities and its scientific production is prominently focused on dementia with Lewy bodies (DLB) thus suggesting the possible occurrence of a bias. Four main categories of dementia were identified: Alzheimer's disease (AD), DLB, fronto-temporal dementia (FTD), vascular dementia (VaD), with other forms in a category apart. The classification rate of new cases of dementia in the tertiary centre was compared with rates reported by secondary centres and rates of recoding were calculated during a follow-up of 2 years. The study classified 2,042 newly diagnosed cases of dementia in a population of 1,370,000 inhabitants of which 315,000 were older than 65. AD was categorized in 48-52 % of cases, DLB in 25-28 %, FTD in 2-4 % and VaD in 17-28 %. During the 2-year follow-up the diagnosis was re-classified in 40 patients (3 %). The rate of recoding was 5 % in the tertiary centre, 2-8 % in referrals from secondary to tertiary centre, 2-10 % in recodings performed in secondary centres and addressed to tertiary centre. Recoding or percentages of new cases of AD or DLB were not different in the comparison between secondary or between secondary and tertiary centres. FTD and VaD were instead significantly recoded. The results

    Stroke services have been centralised in several countries in recent years. Diagnosing acute stroke is challenging and a high proportion of patients admitted to stroke units are diagnosed as a non-stroke condition (stroke mimics). This study aims to describe the stroke mimic patient group, including their impact on stroke services. We analysed routine clinical data from 2,305 consecutive admissions to a stroke unit at St George's Hospital, London. Mimic groupings were derived from 335 individual codes into 17 groupings. From 2,305 admissions, 555 stroke mimic diagnoses were identified (24.2%) and 72% of stroke mimics had at least one stroke risk factor. Common mimic diagnoses were headache, seizure and syncope. Medically unexplained symptoms and decompensation of underlying conditions were also common. Median length of stay was 1 day; a diagnosis of dementia (p=0.028) or needing MRI (p=0.006) was associated with a longer stay. Despite emergency department assessment by specialist clinicians and computed tomography brain, one in four suspected stroke patients admitted to hospital had a non-stroke diagnosis. Stroke mimics represent a heterogeneous patient group with significant impacts on stroke services. Co-location of stroke and acute neurology services may offer advantages where service reorganisation is being considered. © Royal College of Physicians 2016. All rights reserved.

    For our master thesis in medicine, we aimed to determine how many deaths were caused by and with dementia in 2014 and we compared our results with figures from abroad. The mortality rates of 2014 in Flanders were used to determine the amount of deaths related to dementia. These figures are collected by Vlaams Agentschap Zorg & Gezondheid (VAZG) and coded per ICD-10 classification. Of all deaths in Flanders in 2014, 6.60% were caused by dementia and 4.29% were caused by another condition, while also suffering from dementia. Data from abroad are ambiguous. While working on our thesis about "death & dementia", we questioned the reliability of mortality statistics. Possible explanations could be; the complexity of completing death certificates correctly and the challenges involved in properly constructing a chain of causes of death. The accuracy of mortality data can be improved by training and redrafting death certificates.

    A search of previous records in the literatures was done to summarize the opinions for dementia in ancient China. The earliest description of dementia was traced in the Yellow emperor's internal classic, a book written 2000 years ago. Hua Tuo (AD 140-208) in Han Dynasty first denominated "dementia" in the book, Hua Tuo Shen Yi Mi Zhuan. The pathogenesis of dementia could be generalized as the insufficiency of Qi, a flowing energy; the stagnation of phlegm, a harmful liquid substance in the body; and the blood stasis, which were also regarded as therapeutic targets. Therefore, we can conclude that dementia has been recognized and investigated in traditional Chinese medicine, which is definitely before the industrial civilization era.

    Full Text Available Objective. To analyze a potential cumulative effect of life-time depression on dementia and Alzheimer’s disease (AD, with control of vascular factors (VFs. Methods. This study was a subanalysis of the Neurological Disorders in Central Spain (NEDICES study. Past and present depression, VFs, dementia status, and dementia due to AD were documented at study inception. Dementia status was also documented after three years. Four groups were created according to baseline data: never depression (nD, past depression (pD, present depression (prD, and present and past depression (prpD. Logistic regression was used. Results. Data of 1,807 subjects were investigated at baseline (mean age 74.3, 59.3% women, and 1,376 (81.6% subjects were evaluated after three years. The prevalence of dementia at baseline was 6.7%, and dementia incidence was 6.3%. An effect of depression was observed on dementia prevalence (OR [CI 95%] 1.84 [1.01–3.35] for prD and 2.73 [1.08–6.87] for prpD, and on dementia due to AD (OR 1.98 [0.98–3.99] for prD and OR 3.98 [1.48–10.71] for prpD (fully adjusted models, nD as reference. Depression did not influence dementia incidence. Conclusions. Present depression and, particularly, present and past depression are associated with dementia at old age. Multiple mechanisms, including toxic effect of depression on hippocampal neurons, plausibly explain these associations.

    Depression is an important precursor to dementia, but less is known about the role dementia plays in altering the course of depression. We examined whether depression prevalence, incidence, and severity are higher in those with dementia versus those with mild cognitive impairment (MCI), or normal cognition. Prospective cohort study using the longitudinal Uniform Data Set of the National Alzheimer's Coordinating Center (2005-2013). 34 Alzheimer Disease research centers. 27,776 subjects with dementia, MCI, or normal cognition. Depression status was determined by a clinical diagnosis of depression within the prior 2 years and by a Geriatric Depression Scale-Short Form score >5. Rates of depression were significantly higher in subjects with MCI and dementia compared with those with normal cognition at index visit. Controlling for demographics and common chronic conditions, logistic regression analysis revealed elevated depression in those with MCI (OR: 2.40 [95% CI: 2.25, 2.56]) or dementia (OR: 2.64 [95% CI: 2.43, 2.86]) relative to those with normal cognition. In the subjects without depression at the index visit (N = 18,842), those with MCI and dementia had higher probabilities of depression diagnosis 2 years post index visit than those with normal cognition: MCI = 21.7%, dementia = 24.7%, normal cognition = 10.5%. MCI and dementia were associated with significantly higher rates of depression in concurrent as well as prospective analyses. These findings suggest that efforts to effectively engage and treat older adults with dementia will need also to address co-occurring depression.

    To examine the clinical utility of the Cornell Scale for Depression in Dementia (CSDD) in nursing homes. 14 nursing homes in Sydney and Brisbane, Australia. 92 residents with a mean age of 85 years. Consenting residents were assessed by care staff for depression using the CSDD as part of their routine assessment. Specialist clinicians conducted assessment of depression using the Semi-structured Clinical Diagnostic Interview for DSM-IV-TR Axis I Disorders for residents without dementia or the Provisional Diagnostic Criteria for Depression in Alzheimer Disease for residents with dementia to establish expert clinical diagnoses of depression. The diagnostic performance of the staff completed CSDD was analyzed against expert diagnosis using receiver operating characteristic (ROC) curves. The CSDD showed low diagnostic accuracy, with areas under the ROC curve being 0.69, 0.68 and 0.70 for the total sample, residents with dementia and residents without dementia, respectively. At the standard CSDD cutoff score, the sensitivity and specificity were 71% and 59% for the total sample, 69% and 57% for residents with dementia, and 75% and 61% for residents without dementia. The Youden index (for optimizing cut-points) suggested different depression cutoff scores for residents with and without dementia. When administered by nursing home staff the clinical utility of the CSDD is highly questionable in identifying depression. The complexity of the scale, the time required for collecting relevant information, and staff skills and knowledge of assessing depression in older people must be considered when using the CSDD in nursing homes.

    Visual art is an expression of neurological function and how it organizes and interprets perception. The art is predominantly in the right hemisphere, in contrast, the left side, have inhibitory effects on artistic expression. In normal subjects, inhibitory and excitatory mechanisms could interact in a complex harmony, reflecting a paradoxical functional facilitation. Brain diseases such as dementia could change this harmony and then, alter the artistic abilities. Evaluate the art expression in the degenerative diseases. Artistic abilities of 3 painters with degenerative diseases were assessment. Patient 1: A 83 - year old right handed female, diagnosis: Alzheimer's disease. Artistic description: low productivity, simplified versions of earlier and alteration of the visuospatial organization. Patient 2: A 78-year-old right handed female, diagnosis: Primary Progressive Aphasia (PPA); Artistic description: oversimplified drawings which maintaining overall spatial organization, without impair artistic skills. Patient 3: A 68 year-old right handed woman, diagnosis: Fronto-Temporal Dementia (FTD). Artistic description: Increased artistic activity, originality, freedom, utilization of intense colours with perseverative and repetitive copying of similar paintings of her own work. Visual art in Alzheimer's disease is a consequence of visuospatial and constructive disabilities. In contrast, the conservation of this cognitive functions and left asymmetrical involved, in FTD and PPA respectively, suggest artistic preservation, independently of the language injury. The disproportionate functional prevalence of the right over the left could lead to a release of novelty - seeking in art and can contribute to emergent creativity. These observations suggest an organization for art in the brain and proposed bases for further investigations in dementias.

    Full Text Available It can be very difficult to communicate with people with dementia. Each case requires its own unique handling. Not every scenario is covered, as many times your own judgment is what will work, best according to the circumstances. These can change from dawn to evening and from day to day. Never assume things will be the way they were the last time you communicated. Be on your guard. Be adaptable. The article will help get you started to think of your own ways to communicate.

    To determine whether less severe depression spectrum diagnoses such as dysthymia, as well as depression, are associated with risk of developing dementia and mortality in a "real-world" setting. Retrospective cohort study conducted using the Department of Veterans Affairs (VA) National Patient Care Database (1997-2007). VA medical centers in the United States. A total of 281,540 veterans aged 55 years and older without dementia at study baseline (1997-2000). Depression status and incident dementia were ascertained from International Classification of Diseases, Ninth Revision codes during study baseline (1997-2000) and follow-up (2001-2007), respectively. Mortality was ascertained by time of death dates in the VA Vital Status File. Ten percent of veterans had baseline diagnosis of depression and nearly 1% had dysthymia. The unadjusted incidence of dementia was 11.2% in veterans with depression, 10.2% with dysthymia and 6.4% with neither. After adjusting for demographics and comorbidities, patients diagnosed with dysthymia or depression were twice as likely to develop incident dementia compared with those with no dysthymia/depression (adjusted dysthymia hazard ratio [HR]: 1.96, 95% confidence interval [CI]: 1.71-2.25; and depression HR: 2.18, 95% CI: 2.08-2.28). Dysthymia and depression also were associated with increased risk of death (31.6% dysthymia and 32.9% depression versus 28.5% neither; adjusted dysthymia HR: 1.41, 95% CI: 1.31-1.53; and depression HR: 1.47, 95% CI: 1.43-1.51). Findings suggest that older adults with dysthymia or depression need to be monitored closely for adverse outcomes. Future studies should determine whether treatment of depression spectrum disorders may reduce risk of these outcomes.

    Longitudinal studies have shown an increase in cognitive decline many years before clinical diagnosis of dementia. We sought to estimate changes, relative to "normal" aging, in the trajectory of scores on a global cognitive function test-the Cognitive Abilities Screening Instrument (CASI). A prospective cohort study. Community-dwelling members of a U.S. health maintenance organization. Individuals aged 65 and older who had no dementia diagnosis at baseline and had at least two visits with valid CASI test score (N = 4,315). Average longitudinal trajectories, including changes in trajectory before clinical diagnosis in those who would be diagnosed with dementia, were estimated for CASI item response theory (IRT) scores. The impact of sex, education level, and APOE genotype on cognitive trajectories was assessed. Increased cognitive decline relative to "normal" aging was evident in CASI IRT at least 10 years before clinical diagnosis. Male gender, lower education, and presence of ≥1 APOE ε4 alleles were associated with lower average IRT scores. In those who would be diagnosed with dementia, a trajectory change point was estimated at an average of 3.1 years (95% confidence interval 3.0-3.2) before clinical diagnosis, after which cognitive decline appeared to accelerate. The change point did not differ by sex, education level, or APOE ε4 genotype. There were subtle differences in trajectory slopes by sex and APOE ε4 genotype, but not by education. Decline in average global cognitive function was evident at least 10 years before clinical diagnosis of dementia. The decline accelerated about 3 years before clinical diagnosis. © 2017, Copyright the Authors Journal compilation © 2017, The American Geriatrics Society.

    Full Text Available Background/Aims: The aim of the following study is to compare the behavioral and psychological symptoms of dementia (BPSD in patients of Alzheimer disease (AD and vascular dementia (VaD. Materials and Methods: We used National Institute of Neurological and Communicative Disorders and Stroke-Alzheimer′s Disease and Related Disorders Association criteria for diagnosing AD and National Institute of Neurological Disorders and Stroke-Association International pour la Recherche et l′Enseignement en Neurosciences Criteria for diagnosing VaD. VaD cohort was further subcategorized into small vessel and large vessel disease. The severity of cognitive impairment and the BPSD were studied by means of the Clinical Dementia Rating Scale (CDR and the Neuropsychiatric Inventory respectively. Results: We studied 50 AD and 50 VaD patients of whom 38 were small vessels and 12 were large vessels VaD. The severity of dementia was comparable in both groups. The agitation/aggression, depression/dysphoria, anxiety, apathy/indifference, irritability, aberrant motor behavior, appetite and eating behavior and night-time behaviors occurred significantly more frequently in patients with VaD than AD. We found a weak positive correlation between the CDR score and the number of neuropsychiatric symptoms per patient in both cohorts. Elation/euphoria, agitation/aggression was significantly more frequent in patients with large vessel in comparison to small vessel VaD. Conclusions: BPSD are common in both types of dementia and they are more severe in VaD than AD when the groups have similar levels of cognitive impairment.

    Theories from nursing and management provide frameworks for enhancing effectiveness of nursing management practice. The concept nursing management diagnosis has been developed by integrating nursing diagnosis and organizational diagnosis as a basis for nurse manager decision-making. Method triangulation was used to identify problems of managing nursing units, to validate those problems for relevancy to practice, to generate nursing management diagnoses, and to validate the diagnoses. Diagnoses were validated according to a definition of nursing management diagnosis provided. Of the 72 nursing management diagnoses identified, 66 were validated at a 70% level of agreement by nurse managers participating in the study.

    Full Text Available The problems and needs of older people are often associated with mental illness, characterized by a set of clinical manifestations, which constitute important domains for investigation and clinical practice. This paper presents the results of a pilot study whose main purpose was to identify met and unmet needs and to analyze the relationship between those needs, psychopathology and functionality in older people with mental health problems. A sample of 75 patients aged 65 or over, of both sexes, diagnosed with mental illness using ICD-9. The main diagnoses were depression (36% and dementia (29.3%. Most patients had cognitive impairment (MMSE, 52%; CDT, 66.7%, depression (GDS, 61.3%, anxiety (ZAS, 81.3%, and moderate dependence (BI, 49.3% and LI, 77.3%. The main unmet needs found were daytime activities (40%, social benefits (13.3%, company (10.7%, psychological distress (9.3%, and continence (8%. The majority of these unmet needs occur with dementia patients. The majority of the carers of these patients had global needs (met and unmet in terms of psychological distress. Findings also reveal that a low level of functionality is associated with dementia diagnoses. The association analyses suggest that dementia is an important determinant of the functional status and needs.

    On tests of design fluency, an examinee draws as many different designs as possible in a specified time limit while avoiding repetition. The neuroanatomical substrates and diagnostic group differences of design fluency repetition errors and total correct scores were examined in 110 individuals diagnosed with dementia, 53 with mild cognitive impairment (MCI), and 37 neurologically healthy controls. The errors correlated significantly with volumes in the right and left orbitofrontal cortex (OFC), the right and left superior frontal gyrus, the right inferior frontal gyrus, and the right striatum, but did not correlate with volumes in any parietal or temporal lobe regions. Regression analyses indicated that the lateral OFC may be particularly crucial for preventing these errors, even after excluding patients with behavioral variant frontotemporal dementia (bvFTD) from the analysis. Total correct correlated more diffusely with volumes in the right and left frontal and parietal cortex, the right temporal cortex, and the right striatum and thalamus. Patients diagnosed with bvFTD made significantly more repetition errors than patients diagnosed with MCI, Alzheimer's disease, semantic dementia, progressive supranuclear palsy, or corticobasal syndrome. In contrast, total correct design scores did not differentiate the dementia patients. These results highlight the frontal-anatomic specificity of design fluency repetitions. In addition, the results indicate that the propensity to make these errors supports the diagnosis of bvFTD. (JINS, 2012, 18, 1-11).

  12. Non-melanoma skin cancer and risk of Alzheimer's disease and all-cause dementia.

    Full Text Available Cancer patients may be at decreased risk of Alzheimer's disease. This hypothesis is best developed for non-melanoma skin cancer (NMSC, but supportive epidemiological data are sparse. We therefore conducted a nationwide cohort study of the association between NMSC and Alzheimer's disease (main outcome and all-cause dementia. Using Danish medical databases, we identified adults diagnosed with NMSC between 1 January 1980 and 30 November 2013 (n = 216,221 and a comparison cohort of five individuals matched to each NMSC patient by sex and birth year (n = 1,081,097. We followed individuals from the time of diagnosis, or corresponding date for matched comparators, until a dementia diagnosis, death, emigration, or 30 November 2013, whichever came first. We used stratified Cox regression adjusted for comorbidities to compute hazard ratios (HRs associating NMSC with dementia. We computed cumulative risks of dementia, treating death as a competing risk. NMSC was associated with a HR of 0.95 (95% confidence interval [CI]: 0.92-0.98 for Alzheimer's disease and 0.92 (95% CI: 0.90-0.94 for all-cause dementia. HRs were similar for basal cell and squamous cell carcinoma, the two most common forms of NMSC. Estimates of risk reduction were more pronounced in the beginning of follow-up, reaching null after 5-10 years. At the end of follow-up (34 years, cumulative risk of Alzheimer's disease was 4.6% (95% CI: 4.4%-4.8% among patients with NMSC vs. 4.7% (95% CI: 4.6%-4.9% in the comparison cohort. In conclusion, NMSC was associated with 2%-10% reductions in relative risks of Alzheimer's disease and all-cause dementia. However, these small inverse associations may have been caused by ascertainment bias due to decreased awareness of NMSC tumors in persons with undiagnosed early cognitive impairment or by confounding from a more neuroprotective lifestyle among persons with NMSC.

  13. Analysis of affective disorders in patients with vascular dementia

    Full Text Available The outpatient records of 147 patients followed up for diagnosed vascular dementia were analyzed to assess the relationship between affective disorders and severe cognitive impairments. It was found that 7% of the examinees had a history of depressive states. Estimating the development time for vascular dementia could divide the patients into 2 groups: 1 60% of the patients in whom cognitive impairments began to determine its clinical picture just within the first 2 years after identification of affective disorders and 2 40%, in whom cognitive impairments occurred 10—20 years later. In both groups, mental disorders occurred at an equal age in the presence of depressive disorders; in Group 1, vascular dementia developed nearly twice as often as that in Group 2. At the same time, the occurrence of cognitive impairments in Group 1 patients just in the early disease stages is indicative of the organic genesis of affective disorders, as confirmed by the moderately rapid progression of psychopathological symptoms, such as sharpening of personality traits, increased rigidity of psychic processes, emotional lability, variations in affective symptomatology, inadequate remissions, and the presence of neurological symptoms. Another type of a ratio of depressive to severe cognitive disorders was found in the elderly persons in Group 2. The long existence of affective disorders without signs of cognitive diminution leads one to say that they have recurrent depressive disorder with further addition of a comorbid vascular process. These patients showed a fairly high severity of affective pathology that was responsible for more frequent admissions, as well as a phase course with relatively pure remissions without any clear intellectual-mnestic reduction and a predominance of hysterical character traits.

    We compared performance on tests of dysexecutive behaviour (DB) and executive function (EF) in patients with behavioural variant frontotemporal dementia (bvFTD), primary progressive aphasia (PPA) and corticobasal syndrome (CBS). Patients diagnosed with bvFTD (n=124), PPA (n=34) and CBS (n=85) were recruited. EF was measured with the Delis-Kaplan Executive Function System (DKEFS: performance based), and DB was measured with the Frontal Systems Behavior Scale (FrSBe: caregiver-report based). Confirmatory factor analysis characterised the relationship between EF and DB, binary logistic regression evaluated the incremental diagnostic utility of the measures and neuroimaging data from 110 patients identified neural correlates. EF was lowest and DB was highest in bvFTD participants. EF and DB were distinct but related (r=-0.48). Measures correctly classified 89% of bvFTD from CBS patients and 93% of bvFTD from PPA patients-30% and 13% above base rates (59%, 80%), respectively. All modalities were useful in identifying CBS and PPA, whereas DB alone was useful for identifying bvFTD. EF was uniquely associated with caudal left dorsolateral prefrontal and lateral temporo-parietal cortices. DB was uniquely associated with the cingulate (R>L), right subcallosal and right anterior frontal cortex. EF and DB were associated with the rostral dorsolateral prefrontal cortex bilaterally. EF and DB measures displayed criterion and construct validity, had incremental utility at low DB levels (CBS and PPA) and were associated with overlapping and distinct neural correlates. EF and DB procedures can conjointly provide useful diagnostic and descriptive information in identifying and ruling out the dysexecutive syndrome. Published by the BMJ Publishing Group Limited.

    Cerebral hypoperfusion has previously been associated with mild cognitive impairment and dementia in various cross-sectional studies, but whether hypoperfusion precedes neurodegeneration is unknown. We prospectively determined the association of cerebral perfusion with subsequent cognitive decline and development of dementia. Between 2005 and 2012, we measured cerebral blood flow by 2-dimensional phase-contrast magnetic resonance imaging in participants of the population-based Rotterdam Study without dementia. We determined the association of cerebral perfusion (mL/100mL/min) with risk of dementia (until 2015) using a Cox model, adjusting for age, sex, demographics, cardiovascular risk factors, and apolipoprotein E genotype. We repeated analyses for Alzheimer disease and accounting for stroke. We used linear regression to determine change in cognitive performance during 2 consecutive examination rounds in relation to perfusion. Finally, we investigated whether associations were modified by baseline severity of white matter hyperintensities. Of 4759 participants (median age 61.3 years, 55.2% women) with a median follow-up of 6.9 years, 123 participants developed dementia (97 Alzheimer disease). Lower cerebral perfusion was associated with higher risk of dementia (adjusted hazard ratio, 1.31; 95% confidence interval per standard deviation decrease, 1.07-1.61), similar for Alzheimer disease only, and unaltered by accounting for stroke. Risk of dementia with hypoperfusion was higher with increasing severity of white matter hyperintensities (with severe white matter hyperintensities; hazard ratio, 1.54; 95% confidence interval, 1.11-2.14). At cognitive reexamination after on average 5.7 years, lower baseline perfusion was associated with accelerated decline in cognition (global cognition: β=-0.029, P =0.003), which was similar after excluding those with incident dementia, and again most profound in individuals with higher volume of white matter hyperintensities ( P

  17. Diagnosing method for nuclear power plant

    Sonoda, Yukio.

    1991-01-01

    When an abnormality occurs in a nuclear power plant, the abnormality is diagnosed, at present, graphic waveforms obtained by applying signal processing such as high speed Fourier transformation, etc. to fluctuation ingredients (noises) of process signals such as neutron fluxes, and plotting a power spectral density relative to a frequency. However, expert technical knowledges are required for interpreting the waveforms and it is difficult for field operators and persons for maintenance to judge them. Then, in the present invention, patterns of the power spectral density are inputted for pattern recognition by using a neural net so that any of patterns experienced in the past can be identified. If an unknown pattern appears, it is automatically studied for identification in subsequent cases. Then, the known abnormality of the plant can be monitored and causes thereof can be identified in an early stage, as well as it is possible to diagnose unknown abnormalities in subsequent situation. This method is effective for monitoring and maintaining the integrity, and can avoid unnecessary scram to improve plant operation factor. (N.H.)
