摘要:
Alzheimer disease will affect increasing numbers of people as baby boomers (persons born between 1946 and 1964) age. This work reports projections of the incidence of Alzheimer disease(AD) that will occur among older Americans in the future. Education adjusted age-specific incidence rates of clinically diagnosed probable AD were obtained from stratified random samples of residents 65 years of age and older in a geographically defined community. These rates were applied to U.S. Census Bureau projections of the total U.S. population by age and sex to estimate the number of people newly affected each year. The annual number of incident cases is expected to more than double by the midpoint of the twenty-first century: from 377,000 (95% confidence interval = 159,000–595,000) in 1995 to 959,000 (95% confidence interval = 140,000–1,778,000) in 2050. The proportion of new onset casess who are age 85 or older will increase from 40% in 1995 to 62% in 2050 when the youngest of the baby boomers will attain that age. Without progress in preventing or delaying onset of Alzheimer disease, both the number of people with Alzheimer disease and the proportion of the total population affected will increase substantially.

摘要:
PurposeTo evaluate the psychometric properties and patterns of decline on the total score and item scores of the cognitive subscale of the Alzheimer's Disease Assessment Scale (ADAS-Cog) in patients with Alzheimer Disease (AD).MethodsWe analyzed data from 536 AD outpatients randomized to the placebo group in two identical 26-week multicenter drug trials.ResultsMean deterioration at week 26 on the ADAS-Cog total score for subjects with moderate dementia was 84% greater than that for those with milder severity (p< 0.001). After adjusting for this effect, age (p= 0.015) and educational level (p= 0.01) also predicted cognitive decline. In a model, absolute change for most individual ADAS items was less than 10% of the possible change, and it was generally smaller than one-third of the standard deviation of the measure. Measurement error variability was greatest for word recognition and the “placebo” effect was greatest for word recall. Variability increased with trial duration in a model.ConclusionsThere is a relationship between baseline severity and magnitude of cognitive decline. In 6-month trials, measurement error makes a substantial contribution to the variance in ADAS-Cog change scores. Sensitivity to intervention effects will therefore depend both on the variability and magnitude of change. Such data must be considered when designing future trials to minimize measurement error variability and increase sensitivity for specific populations.

摘要:
Background and PurposeThe effect of different diagnostic criteria for detecting dementia in both epidemiological and stroke cohort studies has been shown, but comparison between different assessment methods has only seldom been done. We compared both assessment methods and diagnostic criteria for dementia in a large well-defined stroke cohort.Subject and MethodsA group of 227 of 486 patients aged 55 to 85 years who 3 months after ischemic stroke completed a comprehensive neuropsychological test battery, structured clinical mental status examination of defined cognitive domains with expanded Mini-Mental State Examination. The criteria for dementia were those of the Diagnostic and Statistical Manual of Mental Disorders (DSM-III, DSM-III-R) and the National Institute of Neurological Disorders and Stroke-Associated Internationale pour la Reserche et l'Enseignement en Neurosciences (NINDS-AIREN).ResultsThe main differences between clinical and neuropsychological examinations were seen in memory functions: clinically 24.7% and neuropsychologically 54.2% had impairment in short-term memory and 10.4% versus 5.3% in long-term memory. Accordingly, the prevalence of dementia varied greatly: It was clinically 14.1% by DSM-III, 9.7% by DSM-III-R and 8.4% by NINDS-AIREN criteria. The corresponding frequencies based on neuropsychological evaluation were 27.3%, 4.0% and 25.6%. Between these 3 diagnostic criteria the concordance varied in clinical testing between 59.4%-68.8% (kappa 0.72–0.79) and in neuropsychological testing between 14.5%–81.1% (kappa 0.20–0.86). The concordance between clinical and neuropsychological testing was 56.8% (kappa 0.42) by DSM-III , 31.6% (kappa 0.35) by DSM-III-R and 25.5% (kappa 0.24) by NINDS-AIREN.ConclusionsThe frequency of poststroke dementia and cognitive decline varied sharply when different systems of diagnostic classification and methods were used. This may have serious influences on investigation and treatment of patients. We underline the importance of further debate and studies to refine the categories of cognitive impairment used in the setting of CVD.

摘要:
Systematic evaluation of end-of-life care in dementia has been hampered by a lack of instruments to specifically address those issues that are unique for persons who are dying with dementia. This study evaluated psychometric properties of three scales designed to measure outcomes of care of persons suffering from terminal dementia. A survey of family caregivers whose loved one died during the past year was conducted using a questionnaire that included questions regarding satisfaction with care, physical and emotional symptoms that occurred during the last 90 days of the care recipient's life, and comfort during the dying process. Three scales were developed based on responses from 156 questionnaires: Satisfaction with Care at the End-of-Life in Dementia (SWC-EOLD), Symptom Management at the End-of-Life in Dementia (SM-EOLD) with Physical and Psychological Symptoms subscales, and Comfort Assessment in Dying with Dementia (CAD-EOLD) with four subscales: Physical Distress, Dying Symptoms, Emotional Distress, and Well Being. The three scales developed and evaluated in this study can be used as outcome measures in studies investigating effectiveness of interventions aimed to improve end-of-life care for individuals with dementia.

摘要:
This study assessed relationships between problem behaviors in 199 Alzheimer Disease patients and vulnerability factors in the well being and emotional health of their spouse caregivers. Among caregiver wives and the younger caregiver husbands (64 years old and under) the volume of patient problem behavior was significantly negatively associated with total scores on a summary well being measure. The association was not found within the older husband caregiver group. Considering five subdimensions of the summary well being scale (Anxiety, Depressive Symptoms, Positive Well Being, Vitality and General Health), correlational analyses showed that the total patient problems measure appeared to have impact primarily among wife caregivers, particularly those 64 years old and under. Multiple regression analyses showed that one patient problem behavior category, Emotional Lability, was the single strongest predictor of impaired well being of the caregiver among all five subdimensions of the caregiver well being measure. Although Destructive Behavior of the patient was not significant by itself, an Age by Destructive Behavior interaction showed that high levels of patient Destructive Behavior predicted high levels of Depression, Anxiety, and low levels of Positive Well Being more among younger caregivers. Husband caregivers had significantly higher Anxiety scores than wife caregivers. These findings document how particular patient problem behaviors can affect caregivers. They point up as well how both gender and age may help target which caregivers are most vulnerable to the stress of specific Alzheimer patient behavior problems. They also suggest the utility of examining specific dimensions of well being rather than a total score alone for purposes of understanding the relationship of particular patient behavior problems to caregiver emotional and physical health.

摘要:
There is an urgent need in multinational studies for efficient and sensitive tests for the evaluation of dementias. These tests are used to investigate the regional characteristics of dementias, providing possible insight into the different etiologies of the disorders. These tests are also utilized to assess the outcome of treatment interventions at multinational levels. We validated and standardized the Syndrom Kurztest, a brief European neuropsychological test, in a population of elderly Chileans, possessing high levels of illiteracy. In our sample, the SKT was found to be an effective instrument for the diagnosis of dementias, and for differentiating mild-moderate from severe degrees of the disease. There was a good correlation between the scores on the SKT and the age of the participants, but the gender and the years of schooling had no effect. The test is a useful contribution to the study of dementias, found in the aging developing world, particularly because it can be used in illiterate populations.
