Hippocampal atrophy has previously been reported in both postmortem and magnetic resonance imaging (MRI) studies in patients with schizophrenia compared with normal controls.1- 3 The neuroanatomic specificity of this finding for schizophrenia, however, remains to be determined. We have recently completed a small MRI study that suggests the following: (1) that this abnormality occurs in patients with schizophrenia but not in patients with bipolar disorder; and (2) that the amygdala may be enlarged in patients with bipolar disorder compared with both patients with schizophrenia and healthy control subjects. Herein we describe our preliminary findings.
