Postpartum period
During the subacute postpartum period, psychological disorders may emerge. Among these are postpartum depression, posttraumatic stress disorder, and in rare cases, puerperal psychosis. Postpartum mental illness can affect both mothers and fathers, and is not uncommon. Early detection and adequate treatment is required. Approximately 25% – 85% of postpartum women will experience the "blues" for a few days. Between 7% and 17% may experience clinical depression, with a higher risk among those women with a history of clinical depression. Prevalence of PTSD following normal childbirth (excluding stillbirth or major complications) is estimated to be between 2.8 and 5.6% at 6 weeks postpartum.
Puerperal disorder
Postpartum depression is a moderate to severe depressive episode starting anytime during pregnancy or within the four weeks following delivery. It occurs in 4-20% of pregnancies, depending on its definition. Without treatment, postpartum depression can last for months or years. In addition to affecting the mother’s health, it can interfere with her ability to connect with and care for her baby and may cause the baby to have problems with sleeping, eating, and behavior as he or she grows. In 38% of the cases of postpartum depression, women are still depressed 3 years postpartum. In 0.2% of pregnancies, postpartum depression leads to postpartum psychosis.
