RU-486 in the Treatment of Bipolar Depression

Summary

Bipolar disorder is a chronic and recurrent illness which involves episodes of mania and depression. It is believed that disturbance of the stress hormone system (the hypothalamic-pituitary-adrenal or HPA axis) may cause thinking and memory problems and make the depressive symptoms worse in bipolar disorder. Early studies have shown that mifepristone may have antidepressant effects (may improve the symptoms of depression) and may also maintain or enhance cognition (memory and thinking functions). The purpose of this study is to determine the potential therapeutic efficacy (usefulness) of mifepristone in bipolar depression by assessing the effects of the medication on depressive symptoms and on cognition. This will be done by questionnaires and thinking tests. This study will also try to clarify the functional changes that accompany bipolar disorder by analyzing saliva samples (assessing the stress response by measuring the levels of 2 stress hormones: cortisol and DHEA).
