To compare loss of intellectual functioning in cerebrovascular (CVA) vs. Alzheimer’s disease (AD).
Subjects had Psychiatric disorders (n=26), CVA (n=37), or AD (n=27). Expected premorbid intellectual functioning was computed using educational attainment. Intellectual ability was separated into deviation quotients for Verbal-Conceptual, Attention-Concentration, or Perceptual-Constructional ability, and Psychomotor Speed. The difference between obtained and expected intellectual functioning in each cognitive domain was analyzed using a repeated measures ANOVA with age as a covariate.
