Recent Advances and Controversies in Peripartum Depression.

Peripartum depression, or depression during and/or immediately following pregnancy is a unique psychiatric illness that not only may have unique biological underpinnings but demands unique and thoughtful approaches to management due to the developing neonate. A number of controversies exist in this area ranging from the recent terminology change in psychiatry's Diagnostic and Statistical Manual from "postpartum" to "peripartum" depression, to the safety of antidepressant use during pregnancy, to whether or not antidepressants prevent or decrease peripartum depression. Research in this area is growing and a number of exciting developments have occurred including the identification of two epigenetic biomarkers of peripartum depression that may eventually lead to early identification and intervention, the potential for hormonal treatments and the recommendation for and early institution of universal screening for peripartum depression. These topics are explored and put into context from a clinical management perspective.
