Cognitive impairment associated with morphological brain abnormalities on computed tomography in chronic schizophrenic patients.
The Halstead-Reitan Battery (HRB), including the Wechsler Adult Intelligence Scale, was administered to 15 young chronic schizophrenic patients in an attempt to identify blindly those patients with evidence of morphological brain abnormalities on prior computed tomography (CT). The CT scan status of 12 of 15 (80 per cent) patients was correctly identified solely on the basis of neuropsychological testing. These results supported our hypothesis that impairment on the HRB in chronic schizophrenic patients was associated with morphological abnormalities on the CT scan, and that the positive and negative CT scans of these patients could be predicted accurately.
