Maternal mood disorders and lithium exposure in utero were not associated with poor cognitive development during childhood

Aim This study evaluated whether maternal mood disorders (MMD), particularly bipolar disorder, and lithium treatment during pregnancy influenced the neonatal health and cognition of children born from 2006 to 2010. Methods Our study at Karolinska University Hospital, Stockholm, Sweden, focused on wo...

Description
Summary:Aim This study evaluated whether maternal mood disorders (MMD), particularly bipolar disorder, and lithium treatment during pregnancy influenced the neonatal health and cognition of children born from 2006 to 2010. Methods Our study at Karolinska University Hospital, Stockholm, Sweden, focused on women with and without mood disorders and their children. Information on pharmacotherapy, mental health, delivery and neonatal complications was retrospectively collected from electronic patient records. Children were tested in a blinded manner at four to five years of age with the Wechsler Preschool and Primary Scale of Intelligence, 3rd edition. Maternal health, child health and social situations were evaluated. Results Of the 39 children, 20 were exposed to lithium and MMD during pregnancy, eight were exposed to MMD but not lithium and 11 were not exposed to MMD or lithium. The children's full scale intelligence quotient (IQ), performance IQ and verbal IQ results did not differ significantly between the groups. The processing speed quotient was significantly lower in children exposed to mood disorders, but there was a high level of missing data for this subtest. Conclusion This small, clinical cohort showed no significant association between mothers’ prenatal exposure to lithium or mood disorders and their offspring's IQ.
