Clinical Implications of the Neurosteroid Allopregnanolone in Reproductive Depression.

Abstract

Certain women develop depression with fluctuations in hormone levels whereas other women do not; this hormonally driven depression has been termed reproductive depression. The pathophysiology of reproductive depression differs from that of major depressive disorder, and this distinction has important clinical-including treatment-implications. Recent advances have revealed that the neurosteroid, allopregnanolone, plays a central role in reproductive depression. Appreciation of allopregnanolone's role in reproductive depression aids in selecting targeted treatments and in predicting symptom worsening during subsequent reproductive stages, and it can be used to reduce risk of relapse. This knowledge is also guiding the development of new pharmacologic treatments for reproductive depression.
