[Cortical atrophy in MRI, mental status and neuroleptic treatment effect in schizophrenia]

MR imaging of the head was performed in forty schizophrenics (DSM-IV). Mental status was evaluated before and during 8-weeks of neuroleptic treatment. Cortical atrophy in frontal and temporal regions was found in 40% of subjects. They were older, had longer history of schizophrenia, were less active professionally and were more frequently hospitalized. Patients with and without cortical atrophy in MRI did not differ in the severity of schizophrenic psychopathology at baseline. During neuroleptic treatment negative schizophrenia symptoms were significantly better diminished in patients without cortical atrophy than in subjects with cortical atrophy in MRI; this regarded specially the severity of emotional blunting. Clinical improvement after 8-weeks of neuroleptic administration was less favorable in patients with cortical atrophy.
