Consequences of Depression in Pregnancy

MotherBaby
❏ Suicide❏ Low birth weight, smaller head circumferences, premature delivery, etc.
❏ Unhealthy practices e.g. smoking❏ Poor mother-infant attachment, delayed cognitive and linguistic skills, impaired emotional development, and behavioral issues
❏ Poor nutrition❏ Emotional instability and conduct disorders, attempts at suicide, and require mental health services
❏ Less compliant with prenatal care
❏ Increased pain, nausea, stomach pain, SOB, GI symptoms, etc.

Depression in Pregnant Women

  • 10% to 16% of pregnant women fulfill the diagnostic criteria for MDD, and even more women experience subsyndromal depressive symptoms.

  • Many of depressive symptoms overlap with the physical and mental changes experienced during pregnancy.


Treatment of Depression in Pregnant Women

  • Several meta-analyses of SSRIs: NO increase in risk of congenital malformation with the exception of ?paroxetine.

  • Antidepressants reduce risk for preterm birth and cesarean delivery compared with depressed women untreated BUT has more neonatal complications, including low Apgar score (? Withdrawal syndrome), but benign and self-limited.

  • NO association between TCA use in pregnancy and structural malformations.

  • Fluoxetine and TCA are not behavioral teratogens and do not have a significant effect on cognitive development, language or behavior.

  • Presumed associations between antidepressants and malformations may be complicated by confounders e.g., depression itself, poly-drug interactions.

Treatment Options for Mood Disorders

  • Bupropion, ? venlafaxine, duloxetine, nefazodone, and mirtazepine: NO statistically significant difference or higher than expected rate of congenital anomalies.

  • ECT has long been regarded as a safe and effective treatment for severe depression, life-threatening depression, or failure to respond to antidepressant drugs.

  • Psychotherapy: is considered to be an evidence-based treatment of mood disorders.

  • Mild depression: interpersonal psychotherapy (IPT) or cognitive behavioral therapy (CBT), both having solid evidence-based outcomes data for the treatment of depression.

  • Couples counseling.

Treatment of Mania & Psychosis During Pregnancy

  • Typical antipsychotics, especially high potent, considered as relatively safe compared to other medications.

  • Atypical antipsychotics: no major malformations were found. However, limited data so far, Metabolic syndrome is more with olanzapine and clozapine.

  • Lithium is considered first-line mood stabilizer during pregnancy despite rare cardiac anomaly.

  • Lamotrigine is the safest anticonvulsants mood stabilizers.

  • Avoid valproate & carbamazepine in childbearing women and pregnancy.

Why to Avoid Valproate in Childbearing Women and Pregnancy?

  • Neural tube defects secondary to interference with folate metabolism with first trimester exposure

– Risk = 7-16%

  • Craniofacial defects:

  • Mid-face hypoplasia, short nose with anteverted nostrils, and long upper lip

  • Hypoglycemia, hepatic dysfunction, fingernail hypoplasia, cardiac defects, cleft palate, hypospadias, polydactyly

  • Neonatal toxicity possible

  • Significantly lower mean IQ and verbal IQ

Postpartum Depression

  • 10% to 20% of women who give birth

  • Undetected and commonly underdiagnosed

  • Continuum of Affective Symptoms

  • “Baby blues”… Postpartum psychosis

Treatment of Postpartum Depression

  • SSRIs are medications prescribed most commonly but other agents should be considered.

  • More positive response to SSRIs and Venlafaxine, than to TCAs.

  • Pharmacotherapy should continue for at least 6 months to prevent a relapse of symptoms.

  • The nutritional, immunologic, and psychological benefits of breastfeeding have been well documented.

  • Breastfeeding: All antidepressants are secreted to some degree into the breast milk!

  • Recommend sertraline or Paroxetine: Infant serum levels are low to undetectable.

Antidepressants and Breastfeeding

  • Antidepressants, especially SSRIs, in general are considered to be relatively safe for use during breastfeeding when clinically warranted.

  • Research on long-term effects of SSRI and TCA exposure through breast milk on children shows NO alteration in IQ, language development, or behavior.

  • IPT and CBT are effective.

Postpartum Psychosis

  • Rare: 1 in 500-1000 deliveries.

  • Typically presents within 2 weeks of delivery.

  • Often is a manifestation of bipolar disorder (BP).

  • S/S:

  • Severe insomnia

  • Rapid mood swings

  • Anxiety

  • Psychomotor restlessness

  • Delusions (childbirth themes)

  • Hallucinations

  • Cognitive disturbance, neglecting infant.

  • Assess for suicidal, homicidal/ infanticidal ideations.

  • Treatment: similar to Tx of bipolar disorder, consider ECT.

  • Majority fully recover, some may recur only postpartum, few will end up as BD.

  • For women with bipolar disorder, breastfeeding may be challenging!

  • On-demand breastfeeding disrupts the mother’s sleep and thus increases relapse during the acute postpartum period.

  • Toxicity was reported in breastfed infants exposed to mood stabilizers, including lithium and carbamazepine.

  • Antipsychotics except clozapine are mostly compatible with breastfeeding.
