[The dexamethasone suppression test in agoraphobia with panic attacks. 30 cases]
Abstract:
Among 30 agoraphobic subjects with panic attacks, 6 presented an abnormal dexamethasone suppression test. In non suppressor patients there was a statistical trend towards an excess of major depressive disorders, and of depression in first degree relatives. It suggests that agoraphobia with panic attacks might be a heterogeneous entity. Some agoraphobias with panic attacks might be more related to endogenous depression than to anxiety states.
