Effects of maternal depression on fetal health

Abstract

Case Description Patient is a 27 years old pregnant (18 weeks) female with a past medical history of depression, post-traumatic stress disorder (PTSD), and military sexual trauma admitted for suicidal ideation with intent and plan. During admission, the patient refused all antidepressants after emesis on sertraline and prenatal vitamins. Patient was discharged after clinical stabilization and scheduled for follow-up outpatient. Conclusions Depression during pregnancy can have numerous adverse effects on mother as well as fetal and child development and thus treatment is of the utmost importance. Depression leads to alterations in the serotonin system and the HPA axis, as well as causes epigenetic changes to the infant glucocorticoid receptor gene. Changes in these pathways are most apparent during the second trimester and have downstream consequences leading to altered fetal heart rate variability, preterm birth, and low birth weight. Maternal depression can also lead to altered cortisol reactivity, and delayed motor and cognitive development in childhood. Furthermore, prevalence of depression varies throughout the pregnancy with depression more prevalent in the second and third trimesters. Clinical Significance Pregnant women are less likely to receive any mental health treatment for depression than their non-pregnant counterparts; 49% and 57% respectively, and screening for depression focuses on postpartum screening with few guidelines to screening during pregnancy. Due to the adverse effects on the fetus, maternal surveillance and treatment of depression during pregnancy is essential.
