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.
June 2008 Midwest floods
In addition to physical disease, residents were warned of potential mental health problems. Parents were told to expect developmental regressions in child survivors of the flood, especially those who lost their homes. Even in adults, the stress of applying for services and managing daily activities under catastrophic conditions, along with the summer heat and number of people needing the same things, was expected to exacerbate pre-existing anxiety, depression, or family conflict. The physical and emotional stress of cleaning out flooded homes was only part of the trouble, as parents needed to manage all of this while still caring for children who were home on summer vacation. Longterm consequences were expected as well. "Once the original shock and dismay pass, the losses of such things as wedding photos or treasured family heirlooms can lead to depression and even post-traumatic stress disorder," said one official.
