Behavioral deficits in groups with cerebral vascular lesions.

Established 3 groups of patients with cerebrovascular disease (right hemisphere, left hemisphere, or generalized involvement) by matching 15 triads for age, sex, education, and duration of diagnosed cerebrovascular disease. Intergroup and intragroup comparisons were made of results on a large battery of measures, including psychometric intelligence, motor strength and speed, psychomotor performance, and sensory functions. Tests given included halstead's finger tapping test, halstead's tactual performance test, and wechsler-bellevue, form i, verbal and performance iq values. Significant differences were found between groups with lateralized lesions, whereas the group with generalized involvement tended to occupy an intermediate position. The group with left cerebral damage had a significantly lower verbal than performance iq, whereas this relationship was reversed in the group with right cerebral damage. Motor, psychomotor, and sensory functions were consistently impaired on the side contralateral to the damage hemisphere for the groups with lateralized lesions.
