What is Posttraumatic Stress Disorder (PTSD)?
Posttraumatic stress disorder (PTSD) is a group of mental illnesses that can occur in people who have experienced or seen a traumatic incident. A traumatic event could be anything that puts a lot of stress on a person, such as a natural disaster, an accident, war or combat, or rape, to name a few examples.
It has often been called "shell shock" or "combat fatigue" in the past, but PTSD does not only affect combat veterans. PTSD may affect people of any age, ethnicity, nationality, or culture. Every year, around 3.5 percent of individuals in the United States are affected by PTSD, and one in every eleven people will be diagnosed with PTSD over their lifetime. PTSD affects women twice as much as men.
