Post-Traumatic Stress Disorder is a mental health condition that develops after experiencing or witnessing a traumatic event such as serious accidents, physical assault, abuse, natural disasters, military combat, or other life-threatening situations. It can cause intense emotional and psychological distress that persists long after the traumatic event has ended. Individuals may experience flashbacks, nightmares, intrusive memories, emotional numbness, anxiety, irritability, sleep disturbances, difficulty concentrating, and avoidance of people, places, or situations that trigger traumatic memories. Risk factors include repeated trauma exposure, lack of emotional support, pre-existing mental health conditions, and delayed psychological intervention. If left untreated, it can significantly affect relationships, work performance, daily functioning, and overall quality of life.
