Abstract
Electroencephalogram Patterns in Infants of Depressed Mothers
By Cara M. Lusby
The goal of the current study was to examine the association between maternal prenatal
and postpartum depressive symptoms and infant electroencephalogram (EEG) asymmetry
scores. Participants were 66 women with a history of depression and/or anxiety and their
infants. Women were recruited during pregnancy and their depressive symptoms were
measured at multiple time points throughout pregnancy and the postpartum. Infant EEG
asymmetry scores were collected at 3 and 6 months of age, and mothers' concurrent
depressive symptoms were also measured. Maternal prenatal and postpartum depressive
symptoms separately did not predict infant EEG asymmetry scores at either age, nor did
the additive effect of the two variables. The interaction of maternal prenatal and
postpartum depressive symptoms did significantly predict infant EEG asymmetry scores
at 6 months of age, with a trend in the association at 3 months of age. Specifically, at
infant age 6 months, prenatal depressive symptoms and infant EEG asymmetry scores
were significantly associated among women with high postpartum depressive symptoms
only. Infant EEG asymmetry scores were consistent across contexts at both ages and
were stable across ages in the baseline and free play segments, but not feeding. Findings
highlight the importance of considering both prenatal and postpartum maternal depressive
symptoms in the prediction of infant EEG asymmetry scores, as well as pointing to the
need to further understand the differences between infants who display changes in
patterns versus those whose patterns are stable across ages.
