Abstract:
Neuropsychological test performance and clinical symptoms were assessed in 14 schizophrenic patients at admission to and discharge from an acute inpatient psychiatric service. Despite significant clinical improvement at discharge, no major change in cognitive performance was observed. Furthermore, patients at discharge were significantly impaired compared with normal control subjects case-matched for gender, age, handedness and level of education. The results suggest that some degree of cognitive impairment may be relatively independent from schizophrenic symptoms and that such impairment may represent part of a residual enduring "trait" vulnerability.
