Dexamethasone suppression test and depressive symptoms in schizophrenics and endogenous depressed patients

Dexamethasone Suppression Test (DST) was given to 30 depressed and 30 schizophrenic patients. 10 depressed patients (33%) and 6 schizophrenics (20%) showed abnormal DST; the difference was not statistically significant. The DST-positive and DST-negative patients did not differ significantly in the total scores on anxiety-depression factor of the BPRS, either in the group of depressed patients or in schizophrenics.
