The remainder of the book has five areas of emphasis. The first concerns the 20 to 23 percent of women who suffer from depression sometime during their lives. Five writers cover prevalence, etiology, clinical features, complications, and treatment in adolescence, in pregnancy and the postpartum period, and in midlife. Effective treatments do exist, but many women do not seek health care or do not receive appropriate treatment. The research needed to improve the treatment of depression among women is carefully outlined in this book.
