Investigating the link between childhood adversity and depression using brain imaging

Is this trial a fit for you?

A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.

What this trial studies

This observational study aims to explore the neurobiological mechanisms associated with severe childhood adversity and its impact on the development of major depressive disorder (MDD). By utilizing functional, structural, and molecular imaging techniques, the research will examine oxidative stress abnormalities in the brain of individuals who have experienced significant childhood trauma. The study seeks to differentiate between those who develop psychopathology and those who demonstrate resilience despite early adversity. Understanding these mechanisms is crucial for identifying at-risk individuals and developing targeted therapeutic interventions.
