Good point. Actually, I supect it's even worse than you suggest: mifepristone would also block cortisol receptors of the pituitary and probably the hypothalamus, thus increasing the secretion of ACTH (AdrenoCorticoTropic Hormone) and CRF (Corticotropin-Releasing Factor), respectively, and these hormones may have deleterious effects of their own - indeed, CRF-antagonists are being investigated as possible antidepressants and anxiolytics.
