In the patient brochure Postpartum Depression Facts, the National Institute of Mental Health provides an easy-to-understand description of postpartum depression, its causes, and its symptoms. The brochure, which is available at https://www.nimh.nih.gov/health/publications/postpartum-depression-facts/postpartum-depression-brochure_146657.pdf, also differentiates postpartum depression from the “baby blues” and offers suggestions for women who think they may be experiencing postpartum depression.
