BDNF Val66Met Polymorphism and Posttraumatic Stress Symptoms in U.S. Military Veterans: Protective Effect of Physical Exercise

Posttraumatic stress disorder (PTSD) is a psychiatric disorder characterized by intrusive symptoms, avoidance of trauma reminders, negative thoughts and mood, and alterations in arousal and reactivity that affects approximately 8% of U.S. military veterans in their lifetimes (Wisco et al., 2016). There is increasing interest in identifying genetic markers for PTSD, and understanding how these markers may be moderated by environmental and psychosocial risk and protective factors (e.g., Mota et al., 2018).
