NEUROPSYCHOLOGICAL AND CLINICAL CORRELATES OF TEMPORAL-LOBE ANATOMY IN SCHIZOPHRENIA

Twenty-five DSM-III schizophrenic patients were assessed neuromorphologically and neuropsychologically. Reduced temporal lobes were found through magnetic resonance imaging (MRI) evaluation. In addition, in order to look for the neuropsychological correlates of temporal anatomy in schizophrenia, patients were divided into cognitive normal and abnormal schizophrenics, according to their Luria Nebraska Neuropsychological Battery profile. The latter group had statistically significant temporal lobe abnormalities as assessed by MRI, irrespective of medication, clinical picture or any other relevant variables. The implication of such findings in the light of the diaschisis model is discussed.
