Premenstrual depression, cortisol and oestradiol treatment.

A woman with a 5-year history of frequently recurrent depressions responded poorly to the usual antidepressants. She had a raised plasma cortisol and was made worse by progesterone or by ACTH. An oestradiol/testosterone implant every 4 months abolished all symptoms for at least 8 years, and plasma cortisol returned to normal. This case is relevant to an understanding of premenstrual syndromes and the genesis of depressive illness.
