Dexamethasone suppression test.

Abstract

A connection between a high level of plasma cortisol and psychopathology has long been observed. In depressive patients increased plasma cortisol and non-suppression to the dexamethasone suppression test (DST) has often been described. In this study it was found that endogenously depressed patients more often than non-endogenously depressed patients showed abnormal results to the DST. No difference was found in delta MAX TSH between suppressors and non-suppressors to the DST.
