[The neuropsychological study of 21 patients with expanding cerebral lesions. Preliminary results]

Twenty-one right-handed patients with cerebral expanding space-occupying lesion underwent neuropsychological evaluation before surgery. Testing included the Bender Motor Gestalt Test (BMGT), the Benton Visual Retention Test (BVRT), and four subtests of the Wechsler Adult Intelligence Scale (WAIS), namely Digit span, Digit symbol, Picture completion, and Block design. Statistical analysis showed significant differences in cognitive efficiency between the groups defined by the side and biological behaviour of the lesions.
