The Bayer-Activities of Daily Living Scale (B-ADL) is a 25-item, informant-rated questionnaire which was developed as a brief and internationally applicable instrument for assessing functional disabilities. The scale's target group are elderly patients suffering from mild to moderate dementia or cognitive impairment. To investigate the reliability and(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)
Psychometric characteristics of the Alzheimer's Disease Assessment Scale (ADAS) were examined on the basis of data from 440 patients with dementia of the Alzheimer type that were collected before treatment in a multicenter clinical drug trial. Coefficients of internal consistency of above .80 for the cognitive (ADAS-Cog) and the noncognitive section(More)
The analyses of an international pilot study presented in this article focused on the development of a cross-nationally valid activities-of-daily-living (ADL) scale sensitive to therapeutic effects in patients with mild memory impairment and mild to moderately severe dementia. The present report, which is part of an ongoing international research project,(More)
A new accelerated intelligence test is presented which is known as the multiple selection vocabulary test B. This is a very objective and reliable test measuring the general level of intelligence. The time of testing will be about three to five minutes in the case of persons that are free of any psychiatric disorders. Test results will be only negligibly(More)
The efficacy and tolerance of orally administered vinpocetine was investigated in patients suffering from mild to moderate organic psychosyndromes including primary dementia.

The SKT is a simple and short test for assessing cognitive impairment of memory and attention. The test consists of nine subtests, each limited to a maximum performance time of 60 seconds. Thus, total testing time normally does not exceed 10 to 15 minutes. Test scoring and auditing are also accomplished within a short time and are easily learned. The test(More)
Many of the psychometric instruments employed in dementia research are adapted versions of tests developed in countries different from those in which they are applied. The validity of these instruments has been established in their countries of origin; however, there is little information available regarding their validity when transferred to other(More)
