Best of JAMA 2025: Episode 3:Genetic Architecture and Risk of Childhood Maltreatment Across 5 Psychiatric Diagnoses

This research explores the intricate genetic link between childhood maltreatment and psychiatric conditions, such as ADHD and depression, by analyzing the DNA of over 100,000 individuals. The study reveals that a person's biological predisposition—specifically genetic markers related to ADHD and educational attainment—can significantly influence their likelihood of experiencing early-life trauma. Even when environmental stressors like parental mental illness are present, an individual’s unique genetic profile remains a powerful predictor of risk. Ultimately, the findings highlight that certain demographics, particularly females with high genetic risk scores, face a much higher probability of maltreatment, suggesting that genetics play a vital role in identifying those who need the most protection.
