2.2.1 Disorders Related to Pregnancy

Assessment and Management of Disorders Related to Pregnancy

Pregnancy and childbirth are significant life events that can have a profound impact on a woman’s mental health. Women can experience a range of psychiatric disorders during pregnancy and after childbirth, including depression, anxiety, bipolar disorder, and postpartum psychosis. These disorders can have significant consequences for both the mother and the infant, and it is important to identify and manage them appropriately.

Anxiety/mood symptoms in normal pregnancy:

During pregnancy, symptoms of anxiety and depression are common, particularly during the first and third trimesters. However, unless there is a past history of psychiatric illness, there is no reported increase in the incidence of psychiatric disorders.

Risk factors for developing anxiety and depression during pregnancy include:

  • a family or personal history of depression,
  • ambivalence about the pregnancy,
  • high levels of neuroticism,
  • and lack of social support.

Treatment typically involves psychosocial interventions, and specific psychiatric disorders should be identified and treated accordingly.

Miscarriage and abortion:

Following a miscarriage or abortion more than 50% of women experience an adjustment disorder, which includes significant depressive symptoms. Chronic symptoms are uncommon, but women who have experienced previous miscarriages or abortions or who have conflicts related to cultural or religious beliefs are at higher risk.

Pseudocyesis:

Pseudocyesis, also known as false pregnancy or phantom pregnancy, is a rare condition where a person experiences symptoms of pregnancy, such as missed periods, morning sickness, and abdominal enlargement, despite not being pregnant. The exact cause of pseudocyesis is unknown, but it is thought to be related to psychological factors, such as an intense desire for pregnancy or fear of infertility. It is regarded as a somatoform disorder or a variant of depression, it may present as a complication of post-partum depression or psychosis with amenorrhoea. Treatment for pseudocyesis usually involves psychological counselling and support. Although pseudocyesis does not involve a real pregnancy, the physical and emotional symptoms can be distressing for those affected.

Childbearing in patients with pre-existing mental disorders:

Childbearing in patients with pre-existing mental disorders presents unique challenges and risks. The post-partum period is often associated with increased vulnerability for relapse in many mental health conditions. Factors such as family history, illness severity, medication discontinuation, and lifestyle contribute to the risk of relapse and complications during and after pregnancy. Adequate assessment and multidisciplinary support are crucial for ensuring the well-being of both the parent and child in these cases.

Mental DisorderPregnancy and Post-partum ImpactRisk Factors and Outcomes
SchizophreniaLess likely to relapse if on treatmentRelapse in 20% admitted to inpatient setting; lifestyle factors impact parent/child outcomes
Bipolar DisorderTwo-thirds relapse post-partumFamily history, illness episodes, medication discontinuation; 50-90% recurrence in later pregnancies
Anxiety and Panic DisordersUnclear impact on symptomsConflicting evidence on panic disorder relapse
PTSDNo clear data on relapsePossible risks for pregnancy complications
OCD~30% worsening during pregnancy
Eating DisordersSymptoms may improve during pregnancyPostnatal depression, poorer health outcomes for the baby
Intellectual Disability (ID)Higher pregnancy rates in borderline and mild IDMain issue is not the parent’s IQ, but various factors causing social difficulties
Personality DisordersParenting ability variesAssessment of child’s needs and exposure to social factors; multidisciplinary input needed
