Evaluation of changes in functional performance and activities of daily living skills is an essential aspect of the assessment of elderly individuals with chronic illness. Although functional decrement is a central aspect of Alzheimer's disease (AD), many measures currently utilized to assess these changes have limitations. Empirical and systematic(More)
BACKGROUND Activities of daily living (ADL) deficits are integral components of dementia disorders, and ADL measures are among the most robust markers of the course of Alzheimer's disease (AD). Despite this acknowledged importance, no clearly useful ADL instrument for cross-cultural application in pharmacologic trials in the early stages of AD had been(More)
Alzheimer's disease (AD) is associated with an increased mortality in comparison with aged control populations. The relationship between the clinical and the temporal course of AD has not been well studied over significant intervals. Community-residing patients with probable AD (N = 103, 42 men, mean age = 70.2 +/- 8.0 years) were studied at baseline on(More)
Behavioral disturbances in dementia are some of the most burden-some features with which the caregivers must cope. These symptoms are particularly important because they are likely to be responsive to both pharmacological and nonpharmacological intervention strategies. Before the 1980s, rating scales for patients suffering from dementia did not separate(More)
Conventional psychometric measures uniformly yield zero or near zero scores (i.e., "bottom-out") as patients with Alzheimer's disease (AD) progress to the more severe stages of the illness. Consequently, there are no psychometric measures which objectively assess the mental abilities of AD patients with very severe cognitive impairment. We explored the(More)
