Cognitive recovery after severe head injury: 1. Serial testing on the Wechsler Adult Intelligence Scale

Abstract

The Wechsler Adult Intelligence Scale was administered serially to 40 severely headinjured adults, and the results compared with a matched group of 40 non-injured men. The scores on the verbal subtests showed less initial impairment and were faster to recover to the level of the comparison group than were the non-verbal subtest scores. Verbal IQ of the head-injured group approached that of the comparison group within about one year of injury, while recovery of Performance IQ continued over about three years.
