During the postpartum period, about 85% of women experience some type of mood disturbance. For most the symptoms are mild and short-lived; however, 10 to 15% of women develop more significant symptoms of depression or anxiety. Postpartum psychiatric illness is typically divided into three categories: (1) postpartum blues (2) postpartum depression and (3) postpartum psychosis. It may be useful to conceptualize these disorders as existing along a continuum, where postpartum blues is the mildest and postpartum psychosis the most severe form of postpartum psychiatric illness.

Postpartum Blues

It appears that about 50 to 85% of women experience postpartum blues during the first few weeks after delivery. Given how common this type of mood disturbance is, it may be more accurate to consider the blues as a normal experience following childbirth rather than a psychiatric illness. Rather than feelings of sadness, women with the blues more commonly report mood lability, tearfulness, anxiety or irritability. These symptoms typically peak on the fourth or fifth day after delivery and may last for a few hours or a few days, remitting spontaneously within two weeks of delivery. While these symptoms are unpredictable and often unsettling, they do not interfere with a woman’s ability to function. No specific treatment is required; however, it should be noted that sometimes the blues heralds the development of a more significant mood disorder, particularly in women who have a history of depression. If symptoms of depression persist for longer than two weeks, the patient should be evaluated to rule out a more serious mood disorder.

Postpartum Depression

PPD typically emerges over the first two to three postpartum months but may occur at any point after delivery. Some women actually note the onset of milder depressive symptoms during pregnancy. Postpartum depression is clinically indistinguishable from depression occurring at other times during a woman’s life. The symptoms of postpartum depression include:

  • Depressed or sad mood
  • Tearfulness
  • Loss of interest in usual activities
  • Feelings of guilt
  • Feelings of worthlessness or incompetence
  • Fatigue
  • Sleep disturbance
  • Change in appetite
  • Poor concentration
  • Suicidal thoughts

Significant anxiety symptoms may also occur. Generalized anxiety is common, but some women also develop panic attacks or hypochondriasis. Postpartum obsessive-compulsive disorder has also been reported, where women report disturbing and intrusive thoughts of harming their infant. Especially with milder cases, it may be difficult to detect postpartum depression because many of the symptoms used to diagnose depression (i.e., sleep and appetite disturbance, fatigue) also occur in postpartum women in the absence of depression. The Edinburgh Postnatal Depression Scale is a 10-item questionnaire that may be used to identify women who have PPD. On this scale, a score of 12 or greater or an affirmative answer on question 10 (presence of suicidal thoughts) raise concern and indicate a need for more thorough evaluation.

Postpartum Psychosis

Postpartum psychosis is the most severe form of postpartum psychiatric illness. It is a rare event that occurs in approximately 1 to 2 per 1000 women after childbirth. Its presentation is often dramatic, with onset of symptoms as early as the first 48 to 72 hours after delivery. The majority of women with puerperal psychosis develop symptoms within the first two postpartum weeks.

It appears that in most cases, postpartum psychosis represents an episode of bipolar illness; the symptoms of puerperal psychosis most closely resemble those of a rapidly evolving manic (or mixed) episode. The earliest signs are restlessness, irritability, and insomnia. Women with this disorder exhibit a rapidly shifting depressed or elated mood, disorientation or confusion, and erratic or disorganized behavior. Delusional beliefs are common and often center on the infant. Auditory hallucinations that instruct the mother to harm herself or her infant may also occur. Risk for infanticide, as well as suicide, is significant in this population.

Depression and Obsessive Compulsive Symptoms During the Postpartum Period

Despite several studies which have begun to demonstrate that maternal anxiety during pregnancy can negatively affect offspring neurodevelopment, little attention has been given to postpartum maternal anxiety both by clinicians and researchers. This may be because of the clinical overlap between depression and anxiety symptoms.  Routine postpartum screening generally includes assessing symptoms of depression but anxiety disorders are often masked. Educating clinicians about postpartum anxiety can be very helpful for patients.

Recent studies show pregnancy and childbirth are frequently associated with the onset of the Obsessive Compulsive Disorder (OCD), one type of anxiety disorder. Some women do not have OCD but are bothered by obsessive-compulsive symptoms.

Miller and colleagues aimed to shed light on postpartum depression and anxiety, with and without obsessions, in their two recent studies (Miller, Hoxha, Wisner, & Gossett, 2015a2015b).

A prospective cohort study of 461 women was performed to examine the phenomenology and the most common obsessive and compulsive symptoms present in postpartum women without a diagnosis of obsessive compulsive disorder (OCD). Of the 461 women included, 11.2% screened positive for OCD at 2 weeks postpartum, while 37.5% reported experiencing subclinical obsessions or compulsions. Both at 2 and 6 weeks, among the women who screened negative for OCD, the most commonly reported obsessions were aggression and contamination, and the most common compulsions were cleaning/washing, checking. Women with compulsions, with aggressive, religious and somatic obsessions and obsessions with symmetry were more likely to screen positive for OCD . Miller and colleagues’ data also showed that women with subclinical obsessions or compulsions were much more likely to be experiencing depression, as nearly 25% of these women also screened positive for depression.

In a secondary analysis of their prospective cohort study, Miller and colleagues examined the clinical course of postpartum anxiety and they confirmed the clinical overlap between postpartum anxiety and depression. A large number of women with postpartum depression had anxiety symptoms and obsessive-compulsive symptoms in the immediate postpartum period. At 2 weeks postpartum 19.9% of women with depression were more likely to experience comorbid state-trait anxiety, compared to 1.3% women who screened negative for depression. At both at 2 and 6 weeks postpartum, women with depression were more likely to report obsessions and compulsions compared to women without depression. While state-trait anxiety symptoms tended to resolve with time, obsessive-compulsive symptoms persisted. By 6 months postpartum, there were no differences in anxiety symptoms in women with and without depression, but the difference in obsessive-compulsive symptoms persisted (p=0.017). All this means severe distress for women and therapeutic implications for clinicians.

Given the potential adverse effects of untreated mood and anxiety symptoms on both the mother and child, careful screening and early recognition of anxiety symptoms during the postpartum period is recommended.

What Causes Postpartum Depression?

The postpartum period is characterized by a rapid shift in the hormonal environment. Within the first 48 hours after delivery, estrogen and progesterone concentrations fall dramatically. As these gonadal steroids modulate neurotransmitter systems involved in the regulation of mood, many investigators have proposed a role for these hormonal shirts in the emergence of postpartum affective illness. While it appears that there is no consistent correlation between serum levels of estrogen, progesterone, cortisol, or thyroid hormones and the occurrence of postpartum mood disturbance, some investigators hypothesize that there is a subgroup of women who are particularly sensitive to the hormonal changes that take place after delivery. This population of women may be more vulnerable to PPD and to other hormonally driven mood disturbances, such as those occurring during the premenstrual phase of the menstrual cycle or during the perimenopause.

Other factors may play a role in the etiology of PPD. One of the most consistent findings is that among women who report marital dissatisfaction and/or inadequate social supports, postpartum depressive illness is more common. Several investigators have also demonstrated that stressful life events occurring either during pregnancy or near the time of delivery appear to increase the likelihood of postpartum depression.

While all of these factors may act together to cause PPD, the emergence of this disorder probably reflects an underlying vulnerability to affective illness. Women with histories of major depression or bipolar disorder are more vulnerable to PPD, and women who develop PPD will often go on to have recurrent episodes of depression unrelated to pregnancy or childbirth.

Who is at Risk for Postpartum Depression?

All women are vulnerable to postpartum depression, regardless of age, marital status, education level, or socioeconomic status. While it is impossible to predict who will develop PPD, certain risk factors for PPD have been identified, including:

  • Previous episode of PPD
  • Depression during pregnancy
  • History of depression or bipolar disorder
  • Recent stressful life events
  • Inadequate social supports
  • Marital problem
