Following the birth of a baby, the risk of depression is increased in the mother. Possible causes of postpartum depression include psychological and social stressors, hormonal changes, and genetic factors. The most common form of postpartum depression
is a mild form often referred to as the “blues” that occurs
in up to 50% of women. It begins within days of delivery up to
several weeks later, is of relatively brief duration and severity, and
responds well to reassurance and support.
The most serious form of postpartum depression
is a psychosis that occurs in about 1 to 3 per thousand. It often
begins shortly after delivery, with 40% of the episodes beginning by
day 7. This is a very serious high risk condition characterized
by hallucinations, delusions, and confusion that usually requires
hospitalization and treatment with medication and sometimes with
electroconvulsive therapy (ECT). Although postpartum psychosis has
often been misdiagnosed as schizophrenia, it is almost always a form of
depressive or manic-depressive disorder.
Overall, women with a history of mood disorder (depression or manic depression) prior to pregnancy are at greatly increased risk for a postpartum recurrence.
Consequently, such problems should be anticipated and proper attention
paid to reduction of stressors and the possible preventive use of
medication. Close collaboration between obstetrician,
pediatrician, and mental health professional is essential.
About Postpartum Depression
About 10% of women experience a more severe and sustained depressive episode that meets diagnostic criteria for major depression.
Onset is usually during or after the third week following delivery and
duration can be many months. Professional intervention in the
form of psychotherapy and antidepressant medication is usually quite
helpful.
