Introduction: Why This Case Matters
Postpartum psychiatric illness represents one of the most common complications of childbirth, affecting many new mothers during what should be a joyful time. This detailed case from Massachusetts General Hospital illustrates how obsessive-compulsive disorder (OCD) can emerge or worsen after delivery, particularly with disturbing thoughts about infant harm.
The case highlights the critical importance of proper diagnosis and treatment. Many women suffer in silence due to fear and shame about their symptoms, but effective treatments are available. Understanding that these intrusive thoughts are a medical condition—not a reflection of maternal fitness—can be profoundly liberating for affected mothers.
The Patient's Story: A New Mother's Struggle
A 30-year-old woman presented to the psychiatry clinic four weeks after delivering her first child. She had experienced gestational hypertension (high blood pressure during pregnancy) but otherwise had an uncomplicated pregnancy. At 39 weeks and 1 day gestation, she delivered a healthy baby boy by spontaneous vaginal delivery.
Initially, she appeared engaged and bonded appropriately with her infant. She initiated breastfeeding and participated in postpartum education. However, after discharge on the fourth hospital day, difficulties emerged almost immediately.
The patient struggled with breastfeeding due to the infant's poor latch and developed insomnia, anxiety, and nervousness. She was started on sertraline (an antidepressant) and advised to pump breast milk. Three weeks postpartum, she reported that breastfeeding difficulties were interfering with bonding and measured her blood pressure at 164/101 mm Hg at home.
When evaluated at the hospital, she described insomnia, anxiety, painful nipples, decreased appetite, and mild headache. Her blood pressure was 140/84 mm Hg with a pulse of 107 beats per minute. Medical tests including blood counts, electrolyte levels, and kidney and liver function tests were all normal.
The next day, she told her husband, "I can't go on like this. I can't do this anymore." She had stopped breastfeeding due to nipple bleeding and switched to formula. She felt exhausted, emotionally numb, and sometimes couldn't remember if she had fed the baby. She described feeling lonely, isolated, and unable to engage in most child care duties.
Most distressingly, she began experiencing intrusive thoughts of stabbing her infant and had visual hallucinations of herself holding a knife. These thoughts started after delivery and became increasingly vivid and frequent, causing episodes of intense crying, rapid breathing, and shaking. She avoided the kitchen because knives were present and stopped cooking—an activity she previously enjoyed.
The patient didn't feel comfortable holding or feeding her infant due to these unwanted thoughts but checked on him every few minutes to ensure he was breathing. She repeatedly searched online for reassurance that she wouldn't act on these thoughts and contacted other mothers for support, but was too terrified to tell anyone about the specific intrusive thoughts for fear her baby would be taken away.
Understanding Postpartum Psychiatric Conditions
Healthcare providers evaluating postpartum psychiatric illness focus on three main symptom types: mood symptoms (feeling sad, depressed, or having thoughts of harm), anxiety symptoms (ruminating thoughts, intrusive images, panic attacks), and psychotic symptoms (impaired reality testing, delusions, or hallucinations).
The differential diagnosis for this patient included several possibilities:
- Generalized anxiety disorder: Excessive worry about multiple things
- Normal obsessive thoughts: 34-65% of mothers experience temporary worries about their child's safety that don't impair functioning
- Major depressive disorder: Depressive episode occurring in the postpartum period
- Obsessive-compulsive disorder (OCD): Unwanted, intrusive thoughts and compulsive behaviors
- Postpartum psychosis: A psychiatric emergency involving impaired reality testing
Postpartum depression is the most common peripartum psychiatric disorder, affecting many new mothers. However, OCD symptoms also frequently emerge or worsen during the childbearing years due to hormonal fluctuations. The incidence of new-onset OCD during pregnancy ranges from 2-22%, and during the postpartum period from 2-24%.
Postpartum psychosis is much rarer, occurring in only 0.25-0.6 cases per 1,000 births. Unlike OCD, mothers with psychosis have impaired insight and may show symptoms like decreased need for sleep, delusions, hallucinations, or agitated behavior.
Medical conditions that can cause psychiatric symptoms were also considered, including anemia, infection, thyroid disorders (which affect 5-7% of postpartum women), or autoimmune encephalitis.
How Doctors Reached the Diagnosis
The patient met the Diagnostic and Statistical Manual of Mental Disorders, fifth edition (DSM-5) criteria for obsessive-compulsive disorder. She experienced recurrent intrusive, obsessional thoughts of harming her infant that were egodystonic (inconsistent with her true desires and values).
These thoughts caused significant distress and torment. She developed compulsive behaviors including constantly checking that the infant was alive and breathing, spending hours daily searching online for reassurance, and seeking validation from her husband and mother that she wasn't a "bad mother."
Her symptoms caused substantial social impairment, particularly in her maternal role. Medical evaluation ruled out other medical causes, and her clinical picture couldn't be better explained by another psychiatric disorder. The doctors diagnosed obsessive-compulsive disorder with onset in the postpartum period, most likely with coexisting major depressive disorder.
Treatment Approaches for Postpartum OCD
Treatment for postpartum OCD follows similar principles to OCD treatment in other contexts, with modifications for the postpartum period. The suffering caused by untreated obsessive-compulsive symptoms can be substantial, so the goal is complete symptom amelioration for both the patient and her family.
Cognitive behavioral therapy (CBT) with exposure and response prevention is considered effective for OCD outside the perinatal period, typically requiring 12-16 weekly sessions. However, its feasibility for symptomatic postpartum women may be limited due to time constraints and difficulty accessing resources.
Selective serotonin-reuptake inhibitors (SSRIs) have shown effectiveness for postpartum OCD based on reports dating back three decades, though rigorous studies are limited. Since data don't support the superiority of any specific SSRI, selection should be based on side effect profile and individual patient history. Higher doses are often required for OCD compared to depression treatment.
For patients with coexisting anxiety, adjunctive benzodiazepines like lorazepam or clonazepam may be helpful (except in those with substance use history). An incomplete response to initial treatment is not acceptable given the severe psychological toll of postpartum OCD.
What This Means for Patients and Families
This case illustrates several critical points for patients and healthcare providers. First, intrusive thoughts of harming one's infant are a recognized symptom of postpartum OCD—not a reflection of maternal desire or capability. The tremendous anxiety patients experience about these thoughts and the precautions they take to prevent harm actually demonstrate their protective instincts.
Second, the amalgam of new parenthood stressors with OCD symptoms creates substantial psychological burden. Women need to know that seeking help is essential and that effective treatments are available.
Third, obstetrical providers are increasingly screening for peripartum mental health conditions. The American College of Obstetricians and Gynecologists (ACOG) now recommends universal screening for anxiety symptoms in addition to depression.
Finally, proper diagnosis is essential before initiating treatment. In this case, no assessment for bipolar disorder was conducted before starting sertraline, which highlights the importance of comprehensive evaluation.
Important Limitations to Consider
While this case provides valuable insights, several limitations should be noted. This represents a single case study, not a controlled research trial. Treatment recommendations for postpartum OCD are based largely on evidence from non-peripartum OCD studies, as specific research on postpartum OCD is limited.
The exact timing of mood symptoms wasn't fully documented, though the clinical presentation strongly suggested coexisting major depressive disorder. Digital cognitive behavioral therapy platforms show promise for improving access to care, but their effectiveness specifically for postpartum OCD requires further study.
Augmentation strategies for partial response to initial treatment lack specific research for the postpartum population. More rigorous studies are needed to establish evidence-based guidelines for postpartum OCD treatment.
Recommendations for Patients
If you're experiencing symptoms similar to those described in this case:
- Seek professional help immediately: These symptoms represent a medical condition, not a character flaw or parenting failure
- Share all your symptoms: Including intrusive thoughts you might feel ashamed about—healthcare providers understand these are symptoms of illness
- Know that treatment is available: Both therapy and medication options can help significantly reduce symptoms
- Understand the nature of intrusive thoughts: They're egodystonic (against your true desires) and don't reflect your actual intentions
- Build a support system: Include healthcare providers, family members, and possibly other mothers who've experienced similar challenges
- Advocate for comprehensive evaluation: Ensure you receive proper diagnosis before starting treatment
- Be patient with treatment: Finding the right approach may take time, but persistence pays off
