DNA of soldiers with PTSD offers less protection against trauma

The DNA of soldiers who develop symptoms of PTSD after deployment to a war zone gives them less protection against traumatic experiences. Genetic material typically shows measurable changes after traumatic events. However, these changes are not or are barely seen in the DNA of soldiers who develop symptoms of PTSD. This is the conclusion of a comprehensive study conducted by an international group of researchers from the Dutch Ministry of Defence, University Medical Center Utrecht, Maastricht University and the Veteran Affairs Medical Center in collaboration with the University of California, San Diego. Their research results involving epigenetic changes in the DNA of soldiers exposed to war trauma were recently published in the renowned academic journal Molecular Psychiatry.
