Childhood trauma uncovers genetic link to PTSD

A comprehensive British study has revealed that genetic factors linked to Post-Traumatic Stress Disorder (PTSD) interact differently depending on the type of traumatic experience. These interactions are strongest with childhood traumas, particularly physical neglect. The study showed that childhood traumas, such as abuse and neglect, are associated with more severe symptoms of the disorder and greater interaction with genetic factors, with genes explaining between 1.6% and 2.6% of the variation in symptoms. The findings confirm that the impact of experiences varies according to an individual's genetic background and help in understanding who is more at risk, enabling early support and intervention.
