Post-traumatic stress disorder (PTSD) is a condition that is triggered by a terrifying event — either experiencing it or witnessing it. Symptoms may include flashbacks, nightmares and severe anxiety, as well as uncontrollable thoughts about the event. Some people who go through traumatic events have difficulty adjusting and coping for a while, but they don’t have PTSD — with time and good self-care, they usually get better. But if the symptoms get worse and begin to interfere with your functioning, you may have PTSD.

Accessing effective treatment after PTSD symptoms develop can be critical to reduce symptoms and improve function.
