Bipolar disorder is a complex illness characterised by extremes of mood. It is likely that subtle changes in neuroanatomy contribute to the underlying aetiopathology of the disorder. This study sought to identify differences in the volume of the caudate nucleus in a prospectively confirmed sample of 59 remitted patients compared to 59 individually age and gender matched healthy controls to identify trait related anatomical changes. We did not find a main of effect of diagnosis. However,we did detect gender differences in caudate volume (F>M),age-related volumetric decrease across the study population and a main effect of family history in patients.
