摘要:
Quality of life (QoL) is becoming an increasingly used outcome measure in both clinical practice and research. There are now more than 1000 scales available to measure QoL, and it is important that they are assessed for reliability and validity. This study aims to assess the reliability and validity of the Quality of Life-Alzheimer's Disease (QoL-AD) scale, which is dementia specific and brief and uses the patient's own responses. Two separate samples of people with dementia (sample 1, n = 60; sample 2, n = 201) were assessed. Five focus groups were conducted involving both people with dementia and their caregivers; the focus groups showed that people with dementia had higher hopes for their QoL than their caregivers did for them. Questionnaires about the scale were completed by 71 health care professionals working with people with dementia. The scale was found to have good content validity with no additional items required and all items necessary. It also correlated well with the Dementia Quality of Life scale (0.69) and with the Euroqol-5D scale (0.54), indicating good criterion concurrent validity. Construct validity was also good with the principal components analysis showing all 13 items of the QoL-AD loaded on component 1. Interrater reliability was excellent with all Cohen's kappa values >0.70. Internal consistency was excellent with a Cronbach's alpha coefficient of 0.82. Some people with severe dementia and a Mini-Mental State Examination score as low as 3 were able to satisfactorily complete the QoL-AD. The QoL-AD has very good psychometric properties and can be completed with people with a wide range of severity of dementia.

摘要:
We investigated the relationship of caregivers' health-related quality of life (HRQOL) to the burden of caring for patients with Alzheimer disease (AD) and resource utilization. Caregiver HRQOL was assessed using the SF-12 Mental and Physical Summary scores. Compared with a normative, age-adjusted sample, the 2477 caregivers had lower mental and physical scores (for the latter, only those <54 years of age). Increased caregiver mental functioning was associated with caregiver support and perceived quality of patient medical care, fewer hours of caregiving, and fewer patient behavioral symptoms. The burden of caregiving has substantial effects on HRQOL. Interventions that improve AD status and reduce caregiving hours have the potential to improve caregivers' HRQOL.

摘要:
Patients suffering from Alzheimer disease and other types of dementia gradually lose their decision-making capacity. Advance directives have been widely promoted as a means to maintain some control over one's life in the event of decisional incompetence. This study used data from a recent postal survey conducted in Quebec, Canada to: 1) estimate the prevalence of formal and informal advance directives for health care and research among community-dwelling older adults presumed free of cognitive deficits; and 2) characterize those who have communicated their preferences regarding health care and research participation. Prevalence rates vary from 7.4% (formal advance directives for research) to 42.3% (informal advance directives for health care). Following multivariate logistic regressions, individuals who have communicated their wishes regarding future health care were found to be older, predominantly women, and to more often know someone with cognitive impairment. Those who have expressed their wishes regarding future research involvement were more inclined to participate in research. They were also more likely to have discussed or written advance directives for health care. The finding that only a small proportion of older adults have discussed future research participation with their families points to the need to find effective ways to promote advance directives for research in this population.

摘要:
ObjectiveTo compare behavioral and cognitive testing in the clinical diagnosis of frontotemporal dementia (FTD).MethodsA clinically defined cohort of FTD (n = 52) is compared with 52 Alzheimer disease (AD) patients on a Frontal Behavioral Inventory (FBI) and cognitive tests (e.g., Mini-Mental State Examination, Mattis Dementia Rating Scale, Western Aphasia Battery, Wechsler Intelligence Scale, Wechsler Memory Scale). Fourteen patients with FTD had autopsy confirmation, and their tests are also compared with the rest of the FTD population.ResultsThe FTD and AD groups were matched in sex, duration, and severity of dementia. The total scores on the FBI showed the largest difference. Mini-Mental State Examination and Mattis Dementia Rating Scale total scores did not discriminate between the two groups. Memory subscores were lower in the AD group, and conceptualization and language-related scores were worse in the FTD group. Milder and earlier affected patients, who could carry on a large battery of neuropsychological tests, were much better distinguished by the FBI scores on discriminant function analysis. In contrast to 78% by the cognitive tests, 98% of the FTD and AD patients were differentiated by the FBI.ConclusionsAlthough memory scores were lower in AD and language scores in the FTD population, many of the cognitive tests do not distinguish between FTD and AD. On the other hand, a behavioral inventory is a useful adjunct in the diagnosis of FTD. Postmortem validation was carried out in a sizeable subset of the population, showing similar behavioral and cognitive data.

摘要:
The purpose of this study was to translate the Edinburgh Feeding Evaluation in Dementia Questionnaire (EdFED-Q) from the original English into a Chinese language version and to assess the equivalence of the English and Chinese EdFED-Q versions. To use a directly translated instrument without minimal explanation of the procedures for determining the equivalence between the original and secondary language instrument is questionable. Ensuring equivalence of a translated Chinese version of the EdFED-Q for patients with dementia is an essential prerequisite for identifying culturally specific expressions of feeding difficulty under investigation. Phase 1 consisted of experts doing the initial translation into Chinese and then English back-translations of the questionnaire. Six experts determined the equality of the Chinese and English versions, and five monolingual nurses provided information for the C-EdFED-Q. In phase 2, two bilingual gerontological nurses rated 33 residents with dementia to determine equivalence across time. In phase 3, three groups of bilingual nurses used the Chinese, English, and finally both versions simultaneously to judge a model case's feeding behavior on the videotape. In phase 1, the rating on the equality of the items on the Chinese and English versions was 0.969. In phase 2, kappa coefficients for all items on the C-EdFED-Q and E-EdFED-Q ranged from 0.44 to 1.00. In determining the consistency of the scores for the C-EdFED-Q and E-EdFED-Q between the two raters across time, the intraclass correlation coefficient for the absolute agreement was found to range from 0.85 to 0.90. In phase 3, except for items 6 and 9, all items showed no significant difference among the three groups. Further studies to assess the relationship between constructs and to compare it with known and predicted relationships are recommended.

摘要:
Background and PurposeVascular cognitive impairment and vascular dementia are now seen to extend much beyond the traditional multi-infarct dementia.A more homogeneous subtype is the subcortical ischemic vascular disease (SIVD). We applied magnetic resonance imaging (MRI) criteria based on research criteria for SIVD in a large cohort of patients with ischemic stroke. We compared clinical features of patients with SIVD and patients with other stroke type.Subject and MethodsThe study group comprised 337 of 486 consecutive patients aged 55 to 85 years who 3 months after ischemic stroke completed a comprehensive neuropsychological test battery and MRI, including structured medical, neurologic, and laboratory evaluations; clinical mental status examination; interview of a knowledgeable informant; detailed history of risk factors; and evaluation of stroke type, localization, and syndrome.ResultsPatients with SIVD (n = 86) more often had a history of progressive cognitive decline (22.8% vs. 6.9%,P= 0.0002), walking disorder before stroke (27.9% vs. 2.0%,P= 0.02), and urinary difficulties (12.8% vs. 5.6%,P= 0.028) in comparison with patients with other stroke type (n = 251). Of the study population, 107 (31.8%) had DSM-III dementia. The patients with SIVD more often had DSM-III dementia (40.7% vs. 28.7%,P= 0.04), had less severe stroke as measured by Scandinavian Stroke Scale (56.6 vs. 55.1,P= 0.03), were more dependent in activities of daily living (ADL) functions as measured by FAQ scale (8.9 vs. 5.4,P= 0.001), were more dependent in instrumental activities of daily living (IADL) functions as measured by the Lawton scale (5.5 vs. 6.3,P= 0.01), and were more depressed as measured by the Beck Depression Inventory (11.8 vs. 8.4,P= 0.0003) poststroke than the patients without SIVD. The main cognitive domain that differentiated the patients with SIVD from those without was executive dysfunction (51.2% vs. 38.7%,P= 0.04). According to multiple regression model, apractic-atactic gait disorder (odds ratio 2.82, 95% confidence interval 1.21–6.53), ADL functions (odds ratio 1.04, 95% confidence interval 1.01–1.08), and the Beck Depression Inventory (odds ratio 1.05, 95% confidence interval 1.02–1.09) related to SIVD.ConclusionsThe most significant clinical features of MRI-defined SIVD were found to be apractic-atactic gait, impaired ADL functions, and depression.

摘要:
Clinical and scientific investigations in the field of dementia expanded greatly in the past two decades. Medline citations that addressed Alzheimer disease (AD), the most common dementing disorder, rose from 78 in 1980 to 987 in 1990 and to 1772 in 2000. Underscoring this increased body of knowledge, three practice parameters on dementia were published in 2001 by the Quality Standards Subcommittee of the American Academy of Neurology. Although some older studies are included for context, this review focuses on selected recent advances in dementia that are relevant for the practicing physician. Topics covered include: 1) diagnosis of dementia; 2) risk factors and biomarkers; 3) mild cognitive impairment; 4) the scientific basis for treatment advances in AD; and 5) other dementing disorders.
