What is it? PTSD is not a disease. It stands for Post Traumatic Stress Disorder. It can happen to almost anybody. But it more commonly occurs to more elderly people.
This shows the ages that get PTSD.
Causes: A scary, disturbing, or traumatizing moment that you witnessed in your life. Mostly, it is caused in war.

Signs/symptoms: Loss of interest in previously "fun" events, anxiety, memories, nightmares, flashbacks, agitation, etc.
This picture seems to be a happy flashback. That is not what it would be like for a PTSD patient, but the point is, they would have flashbacks.
Treatments: Cognitive Behavioral Therapy and Eye Movement Desensitization and Reprocessing. It is better to get the treatment as soon as possible. About half of the people won't get treatment because they think of it as a sign of weakness. But you should always go anyway, because PTSD can be scary and life-threatening.
This is what Eye Movement Desensitization and Reprocessing looks like.
Interesting Facts: There are over 3 million cases in the U.S alone every year. 30 percent of Vietnam veterans have PTSD. 20 percent of veterans from the Iraq war also came home with PTSD.
