In this preliminary study, we examined the relationships between prior course and severity of illness and size of the hippocampus, temporal lobes, and third and lateral ventricles in patients with bipolar disorder.The few studies that have investigated relationships between course of illness measures and neuroanatomic structures in patients with bipolar disorder found divergent results.Twenty-six outpatients, who met Diagnostic and Statistical Manual, Third Edition - Revised (DSM-III-R) criteria for bipolar disorder, received a magnetic resonance imaging (MRI) scan, from which volumes of the temporal lobes, hippocampi, third ventricle, and areas of the lateral ventricles were calculated. Prior course of illness variables were determined using the NIMH Life-Chart Method and were correlated to the volumetric measures of neuroanatomic structures using multiple regression analyses.A longer duration of illness was paradoxically associated with a larger left temporal lobe volume whether patients with a history of substance abuse were removed from the analyses.Additional studies are needed to both replicate and further examine the association of prior course of illness and larger hippocampal and ventricular volumes in bipolar disorder. |
