For you, the first visits with a newborn are a busy balancing act of gentle physical exam and empathic parent reassurance and education. It’s difficult to imagine that much else could fit into these visits. But your providing weekly and then monthly checks on a newborn puts you in a unique position to detect postpartum depression in that baby’s mother (as are obstetricians at the 6-week follow up). Postpartum depression is relatively common and very treatable, but it can go untreated because of the silence that is often grounded in shame and stigma. A few days of “baby blues” secondary to being tired and hormonal changes is quite different from persistent postpartum depression. Early detection of postpartum depression and referral to a psychiatrist can relieve extraordinary suffering in a parent and stress in a family, and can protect the critical relationship developing between mother and baby.

Postpartum depression was rarely discussed as recently as 30 years ago; it was not formally recognized by psychiatrists as a distinct illness in the Diagnostic and Statistical Manual of Mental Disorders (DSM) until its fourth edition, released in 1994. It is only slightly more common than depression in nonpregnant women of childbearing age: the Centers for Disease Control and Prevention estimated that depression affects 13% of women in the postpartum period, compared with 11% of age-matched controls. It is, however, more likely to be severe than depression in the nonperipartum woman (Gen. Hosp. Psychiatry 2004;26:289-95).Teenage mothers, women with a personal or family history of depression, women giving birth to twins or triplets, women with a history of miscarriage or stillbirth, and women who experienced premature labor and delivery all appear to be at elevated risk for postpartum depression. While other stressors such as marital conflict, single parenthood, or financial strain are challenging for new mothers, they have not been shown to significantly increase the risk of postpartum depression. It also should be noted that a history of previous deliveries without a postpartum mood disorder is not protective or predictive.
The diagnostic criteria for postpartum depression are the same as for a major depressive episode, except that symptoms start in the 4 weeks after the delivery of a baby (although they may be present during the pregnancy or may not be noted until weeks or months later). This can make it easy to mistake depression for the “baby blues” – a period of weepiness, anxiety, moodiness, and exhaustion that commonly occurs to new mothers. These symptoms affect as many as 75% of mothers in the first few days after delivery and can be very unsettling, but the symptoms always improve within 2 weeks, whereas postpartum depression will persist or worsen. Although it can be severe, postpartum depression will improve with treatment, typically psychotherapy and possibly medication. Without treatment, postpartum depression can persist for months. It may remit spontaneously after a substantial period, but it also may worsen. Untreated postpartum depression can (rarely) deteriorate into postpartum psychosis, which usually requires hospitalization and more significant psychopharmacologic intervention. Failure to detect and treat depression in new mothers can lead to a number of complications for the mother, ranging from difficulty with breastfeeding and forming an attachment with her newborn to an inability to return to work. It also raises the risk for suicide, which accounts for 20% of all deaths in the postpartum population (Arch. Womens Ment. Health 2005;8:77-87).The catastrophe of infanticide is diminishingly rare, but almost always associated with untreated postpartum depression or psychosis.

The complications of untreated depression do not affect only the symptomatic mother. There have been many studies that have demonstrated the negative developmental effects of maternal depression on children of all ages, from infancy through adolescence. Maternal depression in the newborn period can be especially disruptive of development, as it can interfere with healthy attachment and an infant’s development of the fundamentals of self-regulation. Infants of depressed mothers are more likely to be passive, withdrawn, and dysregulated. Cognitive development in infants and toddlers of depressed mothers is frequently delayed. Toddler children of depressed mothers more frequently display internalizing (depressed and anxious) and externalizing (disruptive) behavioral symptoms. Mood, anxiety, conduct disorders, and attention-deficit/hyperactivity disorder are more common in the school-age and adolescent children of depressed mothers than in peers whose mothers are not depressed (Paediatr. Child Health 2004;9:575-83). Clearly, the consequences of untreated depression in a mother on even the youngest children can be profound and persistent. And, most importantly, they are preventable.
Why would new mothers experiencing such uncomfortable symptoms fail to actively seek help? There are many reasons for their silent suffering. Many new mothers assume that their symptoms are the “baby blues,” a normal part of the monumental adjustment from pregnancy to motherhood. When their symptoms fail to improve in the first few weeks as promised by friends or clinicians, they often assume that they are personally inadequate, not up to the task of parenting. Such feelings of worthlessness and guilt are actually common symptoms of depression, and contribute to the shame and silence that accompany depressive disorders. (This is one of the reasons depression is described as an “internalizing” disorder.) These feelings (or symptoms) of guilt often are heightened by popular expectations that new mothers should be experiencing delight and joy in the new child. While all of the attention was on the mother during her pregnancy, the focus of friends, family, and clinicians usually shifts entirely to the infant after delivery. Although the reality of postpartum depression is more comfortably and openly discussed now than a generation ago, these forces continue to compel most women suffering from depression to remain silent.
