PTSD

PTSD Overview

Post-traumatic stress disorder (PTSD) is a mental health disorder that can develop in anyone who experiences physical or emotional trauma. Anyone who experiences—or witnesses—a single traumatic event such as a terrorist attack or a tornado, or chronic trauma, such as war, sexual abuse, or family violence, may develop PTSD. An experience of shock, danger, or fear automatically results in the body’s natural sympathetic response of fight or flight; however, when that stress reaction continues even though they are not in danger, PTSD can develop. Traumatic events usually occur unexpectedly, triggering fear and the body’s natural sympathetic response, known as stress. This is a normal response intended to protect a person from harm. Stress stimulates the nervous system, the endocrine system and the immune system, causing the release of adrenergic hormones and chemicals. Physical symptoms include increased heart rate and blood pressure, blood glucose levels rise, all in an effort to prepare the person to escape danger or deal with it more effectively if escape is not possible. Everyone experiences stress and trauma throughout life; however, when the stressful event interferes with normal daily function and relationships, it becomes identified as PTSD, which requires treatment to restore the ability to adapt and cope.
