Wechsler variables as a function of age and neurologic status.

Scores on Wechsler variables were analyzed in groups of patients broken down by age and neurologic status. No differences as a function of age were found in intelligence or memory. Timed Performance subtest results were related to age, but apparent Verbal subtest age differences were eliminated by the introduction of education as a covariate. Neurologic status showed significant effects on intelligence and memory and on all but 3 Wechsler subtests. No significant interactions between age and neurologic status were seen.
