Magnetic resonance imaging was used to measure the volumes of the
caudate, putamen, and globus pallidus of 25 schizophrenic patients (17 men
and eight women) and 26 age- and sex-matched comparison subjects (18 men
and eight women). Schizophrenic patients had significantly larger right and
left globus pallidus and right putamen volumes than comparison subjects.
There were no significant differences between schizophrenic patients with
and without persistent tardive dyskinesia in the volume of any of the three
structures.Abstract Teaser
