Study of Depression, Peptides, and Steroids in Cushing's Syndrome

OBJECTIVES: I. Study the relationship between dysregulation of the hypothalamic-pituitary-adrenal (HPA) axis and disorders of mood, vegetative function, and cognition in patients with Cushing's disease.

II. Identify subgroups of patients with Cushing's disease who differ in the presence and severity of the depressive syndrome, and uncover HPA axis dysregulation differences among them using corticotropin-releasing hormone, metyrapone, and dexamethasone challenge testing.
