Serial dexamethasone suppression tests in simultaneous panic and depressive disorders

Recent work suggests that the simultaneous occurrence of major depressive disorder (MDD) and panic disorder (PD) may be of relevance for clinical findings, therapeutic outcome, and prognosis. It is of interest to know whether or not this relevance extends to biological findings. We addressed this question through comparison of serial Dexamethasone Suppression Test (DST) results in patients who had either MDD alone or simultaneous MDD and PD. We were unable to describe differences between the groups.
