Bipolar Disorder in Pregnancy and the Postpartum Period

July 3, 2020 · Posted in Risk Factors 

At the 2020 meeting of the International Society for Bipolar Disorders, researcher Veerle Bergink reported several findings from a recent meta-analysis of articles on pregnancy and bipolar disorder. Bergink and colleagues found that pregnant women with bipolar disorder have a 37% risk of a postpartum relapse, more than twice the risk of postpartum mental disorders in the general population.

Using lithium as a treatment in the first trimester of pregnancy increased risk of congenital malformations in the fetus, but the risk was much smaller than previously thought and could be monitored by ultrasound.

Bergink and colleagues also reported that in a sample of 645 women with first-onset postpartum psychosis who received followup over a period of 7 to 25 years, 43% had no subsequent severe episodes outside of the postpartum period.

Another finding was that women with postpartum severe depression or mania had abnormalities in T cells, which are important in immune response.
