PTSD develops after traumatic experiences. Genetic factors explain 30–40% of risk and influence how individuals respond to and recover from trauma.
How Genetic Is Post-Traumatic Stress Disorder?
Genetics plays a meaningful role in Post-Traumatic Stress Disorder, with heritability estimated at around 30%. However, environmental factors — including diet, lifestyle, and exposure — also significantly influence risk.
