ADAS is a global
rating scale which is used to summarize whether an individual
has cognitive impairments consistent with Alzheimer's
disease. Test items assess various functions including
language ability (speech and comprehension), memory,
ability to copy geometric figures, and orientation to current
time and place. Patients are given a score for each area,
with higher scores indicating more dysfunction. Subjects with
Alzheimer's disease tend to score consistently higher than
healthy elderly patients.
The ADAS was originally developed by W.
G. Rosen, R. C. Mohs and K. L. Davis ("A new rating scale
for Alzheimer's disease," in American Journal of Psychiatry,
vol. 141, pp. 1356-1364.)
