O3. Depression Severity Over 18 Months in Adolescent Girls is Associated With Stress-Linked Cortical Morphometry

Harsh environmental exposures (i.e., trauma) are postulated to impact grey matter development, as well as increase vulnerability to depression. However, it remains unclear whether burden of common stressful life events in a typically-developing adolescent sample has connections to cortical grey matter health or whether such neural markers signal risk for adolescent depression. In this study, we aimed to address these gaps using cortical...
