Abstract
Post-Traumatic Stress Disorder (PTSD) is a debilitating mental health condition that significantly affects individuals who have experienced trauma. PTSD has substantial impact on mental, emotional, and physical well-being, encompassing emotional distress, impaired social functioning, cognitive deficits, adverse physical health outcomes, and even suicidal ideation. Early diagnosis of PTSD is vital, given its profound consequences. The diagnostic process is intricate and involves diverse criteria and assessment tools. This research explores these diagnostic methods, focusing on the criteria outlined in the Diagnostic and Statistical Manual of Mental Disorders (DSM) and the International Classification of Diseases (ICD). Furthermore, it emphasizes the importance of self-rating scales and a groundbreaking discovery related to saliva as a potential diagnostic marker for PTSD. The evolution of diagnostic criteria, diagnostic frameworks in the DSM-5 and ICD-11, self-rating scales like the PTSD Checklist (PCL), and the potential of saliva as a diagnostic criterion are discussed. These diagnostic tools offer valuable insights for the assessment and diagnosis of PTSD, enhancing treatment and support for affected individuals.
