Post-traumatic stress disorder (PTSD) is a type of anxiety disorder that's triggered by a traumatic event. You can develop post-traumatic stress disorder when you experience or witness an event that causes intense fear, helplessness or horror.
Many people who are involved in traumatic events have a brief period of difficulty adjusting and coping. But with time and healthy coping methods, such traumatic reactions usually get better. In some cases, though, the symptoms can get worse or last for months or even years. Sometimes they may completely disrupt your life. In these cases, you may have post-traumatic stress disorder.
Getting treatment as soon as possible after post-traumatic stress disorder symptoms develop may prevent PTSD from becoming a long-term condition.
