Wechsler intelligence scale profiles in Alzheimer type dementia and healthy ageing

Abstract

Meta‐analytic techniques were used to integrate the Wechsler Adult Intelligence (WAIS) scores of healthy elderly subjects and Alzheimer type dementia patients from 21 studies. Although age‐scaled scores for demented subjects were lower than those of healthy elderly subjects for all subtests, the profiles for both groups were essentially parallel, with no subtest having significantly poorer scores than the others for the dementia patients. The pattern confirms other findings that verbal tests do not ‘hold’ to a greater degree than performance tests in dementia. Show more
