Abstract

OBJECTIVES
This study was designed to verify neuro-developmental hypothesis of schizophrenia and mood disorder. METHOD: We performed Brain Magnetic Resonance Imaging study in 34 schizophrenic patients, 18 mood disorder patients and 22 controls and compared the incidence and the size of carum septi pellucidi (CSP).
RESULTS
The incidences of CSP in schizophrenia, mood disorder and controls were 61%, 61%, and 41%, respectively. The incidences of large CSP, defined as largest diameter larger than 3mm in T1-weighted image, were 24% in schizophrenic patients, 11% in mood disorder patients, and 5% in controls. But they didn't show statistically significant differences.
CONCLUSION
We could find the tendency that the incidence of CSP was high as following order; schizophrenia, mood disorder, controls. But it was not statistically significant difference. To verify neuro-developmental hypothesis, we need larger pool of patients and better study design.
