Abstract
Studies addressing the relationship between a history of obstetric complications (OCs) and neurological abnormalities in schizophrenia have produced contradictory findings. Using a pre-posttreatment design in a neuroleptic-naive sample of psychotic patients, we examined the relationship of a history of OC to primary and drug-induced neurological signs. Fifty neuroleptic-naive non-affective psychotic inpatients were assessed for a history of OC by using the McNeil-Sjöström scale, and for neurological signs including parkinsonism, dyskinesia, akathisia and catatonia, which were rated before and after inception of neuroleptic treatment. A subsample of 28 patients were also examined for neurological soft-signs. Ratings of OCs were related to admission levels of parkinsonism, dyskinesia, akathisia and neurological soft-signs, but not to levels of catatonia. By obstetric period, pregnancy complications were related to levels of parkinsonism, dyskinesia, and neurological soft-signs, and neonatal complications were related to levels of akathisia. Drug-induced neurological signs were not associated with a history of OCs. We argue that the association pattern between a history of OCs and primary neurological signs from several domains suggests a causal link among these variables. Having a history of OCs does not convey a vulnerability for developing drug-induced neurological signs in the short term.
