Neuropsychological prognosis and clinical recovery

This report examines prognostic implications of neuropsychological deficit for clinical symptomatic improvement. Neuropsychological performance levels are related to the Brief Psychiatric Rating Scale thinking disturbance, paranoid disturbance, withdrawal/retardation, and anxiety/depression scales at hospital admission and discharge in 68 schizophrenic and psychotic and nonpsychotic mood disorder patients. Findings indicate a relationship between neurocognitive deficit and thinking disturbance at admission; however, neuropsychological impairment predicts blunted affect/emotional withdrawal at discharge, after the acute psychopathology resolves. Neuropsychological deficit is nonspecific, occurring across a broad range of cognitive-perceptual functions. These data suggest that neuropsychological dysfunction may be prognostic of a more chronic residual disorder in both schizophrenia and major psychotic and nonpsychotic mood disorder syndromes.
