[Postpartum depression]

Postpartum depression. Postpartum depression affects over 10% of women in the year following childbirth; it has deleterious consequences for the mother - especially a significant risk of recurrence over the life - and the child development. Its detection is sometimes difficult because of polymorphic symptoms, whose severity is typically moderate but up to melancholy. Its main differential diagnosis is the postpartum blues. It represents a major public health issue. Postpartum depression is a multifactorial disease. Its prevention requires a better understanding of its determinants, which allows an early and targeted action on women who are most at risk. Once diagnosed, a collegial management is required to avoid the impact on the mother and child. Psychotherapy and/or antidepressant therapy may be necessary.
