Individuals who have witnessed or encountered a traumatic incident, such as physical or sexual assault, natural catastrophes, accidents, terrorist attacks, or war, may develop a condition called Post Traumatic Stress Disorder (PTSD). People with PTSD may feel intense fear, helplessness, or horror after the event. They may have flashbacks, nightmares, and intrusive thoughts about the traumatic event. Also, common symptoms are avoidance of places or things that remind them of the event and difficulty feeling positive emotions. PTSD can make it extremely difficult for people to function normally in their everyday lives. Current treatments available only help people manage these symptoms.
