Article Correctness Is Author's Responsibility: New PTSD biotypes enables improved tests, sheds light on divergent treatments efficacy

(Walter Reed Army Institute of Research) Researchers from the PTSD Systems Biology Consortium identified distinct biotypes for post-traumatic stress disorder, the first of their kind for any psychological disorder. These biotypes can refine the development of screening tools and may explain the varying efficacy of PTSD treatments. PTSD diagnosis is complicated by over-reliance on self-reporting of patient symptoms, particularly underreporting signs of distress due to perceived stigma. Researchers identified two PTSD biotypes with differing genetic markers and underlying mechanisms of disease.
