A study in JAMA Pediatrics showed that babies whose mothers took selective serotonin reuptake inhibitors for depression during pregnancy had significantly increased brain volume in the right amygdala and right insula, which are involved in emotional processing, as well as significantly greater connectivity between both brain regions, compared with those whose mothers had untreated depression and those whose mothers didn't have depression. The findings should prompt "further research on the potential long-term behavioral and psychological outcomes of these neurodevelopmental changes," researchers said.
