Childhood trauma can lead to PTSD in adults, while also affecting them on a genetic level.
According to a study published in the journal Biological Psychiatry, adults with PTSD who had a history of childhood trauma had a significantly shorter region of DNA proteins known as the telomere -- a region of repetitive DNA sequence at the end of a chromosome which protects the chromosome from deterioration. Previous studies have linked short telomere length with accelerated aging and a greater risk of cardiovascular disease, cancer, and other degenerative conditions.
The study examined a total of 90 people -- 47 with PTSD and 43 without. The subjects with PTSD were found to have an average telomere length shorter than that of the non-PTSD subjects.
