Abstract
Twenty-seven chronic schizophrenic patients and nine other psychiatric patients closely matched in education were compared on the Halstead-Reitan Battery and the Wechsler Adult Intelligence Scale (WAIS). The schizophrenic patients as a group showed significantly poorer performance on the WAIS (full scale: X +/- SD, 92.9 +/- 2.9 vs. 110.8 +/- 2.1, p less than .002) and the Halstead-Reitan Battery (HRB; Average Impairment Range = 2.1 +/- .2 vs. 1.12 +/- .06, p less than .003). In addition the schizophrenic patients did significantly worse than did nonschizophrenic patients on all WAIS subtests and scored in the impaired range on most HRB subtests. Computed axial tomography scans revealed large ventricles on nine schizophrenic patients and cortical atrophy on three others. Among schizophrenics, the enlarged ventricle group consistently scored the worst. No relationship was seen between neuropsychological test performance and degree of ongoing psychopathology as measured by the Brief Psychiatric Rating Scale. These findings are consistent with previous reports of cognitive impairment in schizophrenia and are discussed in terms of regional localization. They provide additional evidence that the impairment is related to the disease process and that structural abnormalities are associated with the more severe condition.
