Neural correlates of perinatal depression and anxiety

Funded by an NIMH R21 grant (R21 MH116481; PI: Hajcak) at Florida State University, this study examines whether event-related potentials (ERPs) measured in pregnancy predict changes in depression and anxiety symptoms across the perinatal period. The goal of this project is to determine whether measures of reward-related neural activity could be used to improve the prediction of increased depression during the postpartum period.

We brought EEG systems into a community OB/GYN clinic to collect data from pregnant patients before and after their obstetrical appointments and also followed up with them in the postnatal period.

So far, we have found that blunted neural reward responsiveness in pregnancy is a predictor of increased depressive symptoms in pregnancy, worse course of depressive symptoms in the late postpartum period, and poorer maternal bonding with the infant. We have also found two ERP predictors of increased depression and anxiety in the early postpartum period: the P300 and the late positive potential (LPP).
