While postpartum depression (PPD) is typically considered to be a woman’s illness, a number of studies have suggested that, although men do not experience any of the dramatic physiologic or hormonal changes that go along with pregnancy, new fathers may also suffer from PPD. The most recent study was a meta-analysis published in the May 19th issue of the Journal of the American Medical Association.
As part of the landmark health insurance reform bill that passed Congress on Monday, the Melanie Blocker Stokes MOTHERS Act – legislation sponsored by U.S. Senator Robert Menendez (D-NJ) – will become law. The legislation will establish a comprehensive federal commitment to combating postpartum depression through new research, education initiatives and voluntarily support service programs. The legislation is designed to:
Approximately 10-15% of women will experience mood symptoms that meet criteria for a Major Depressive Episode during the postpartum period. However, as many as 50% of women may experience some level of depressive symptoms during the postpartum period. Recent evidence suggests that even depressive symptoms that do not qualify for a diagnosis of postpartum depression may have a negative impact on both mother and child. In spite of the fact that so many postpartum women will experience depressive symptoms, little research has been conducted in order to identify potentially modifiable factors that could reduce the risk of depressive symptoms or the development of a major depressive episode during this time.
Postpartum psychosis occurs in about 1 to 2 per 1000 women after delivery. While there appears to be a strong link between postpartum psychosis and bipolar disorder, it is estimated that about half of women who present with postpartum psychosis have no psychiatric history prior to delivery, making it difficult to identify those women who are at greatest risk for this illness.  A recent study, using data from the Swedish Medical Birth Registry, has examined possible risk factors that may be used to identify women at risk for postpartum psychosis.
The lifetime prevalence rate of obsessive-compulsive disorder (OCD) has been consistently estimated to be 2%-3% in the general adult population throughout the world, making OCD one of more common psychiatric diagnoses; however research on OCD in pregnancy and peurperium has been limited.
While many women who smoke successfully quit smoking during pregnancy, most of these women return to smoking within 12 months of delivery. Several studies have suggested that certain factors may increase the risk of postpartum relapse, including unwanted pregnancy, multiparity, and stressful life events. Two recent studies indicate that postpartum depressive symptoms may also increase the risk of smoking relapse after delivery.
About 15% of women suffer from depression during pregnancy, and many reports have suggested that depression during pregnancy may have negative effects on the fetus.  A new study from researchers at the University of Michigan indicates a link between depression during pregnancy and infant sleep problems.
Maguire and Mody's report, GABAA R Plasticity during Pregnancy: Relevance to Postpartum Depression, in the July 2008, Neuron, provides evidence that an abnormal Gamma-aminobutyric acid (GABAA) receptor subunit in pregnant mice may be a useful model for postpartum depression. The report describes how GABAA receptors, specifically, the delta-subunit-containing GABA receptor, are a preferred target for neurosteroids. They designed a study to identify functional changes in these receptors during pregnancy and postpartum and then looked at possible behavioral correlates in the mice.Â
Parental use of physical punishment early in childhood may be associated with subsequent maladaptive behaviors such as child aggression and impaired social information processing. There are links between certain childhood behaviors and risk for parental use of physical punishment, although cause and effect are difficult to establish with these associations. Higher rates of physical punishment correlate with maternal depression and domestic violence.
Last Wednesday, the UNC Medical Center opened an outpatient clinic for women with postpartum depression, and on November 3rd opened an inpatient unit for women with postpartum depression. The inpatient unit is called "the first of its kind" in the United States, and is a progressive example of specialized health care initiatives for improved screening, diagnosis, and treatment of postpartum mood disorders in the US.
