Post-traumatic stress disorder (PTSD) is a mental health condition that’s 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.
Most people who go through traumatic events may have temporary difficulty adjusting and coping,
but with time and good self-care, they usually get better. If the symptoms get worse, last for months
or even years, and interfere with your day-to-day functioning, you may have PTSD.
Getting effective treatment after PTSD symptoms develop can be critical to reduce symptoms and
improve function.
Post-traumatic stress disorder symptoms may start within one month of a traumatic event, but
sometimes symptoms may not appear until years after the event. These symptoms cause significant
problems in social or work situations and in relationships. They can also interfere with your ability to
go about your normal daily tasks.
PTSD symptoms are generally grouped into four types: intrusive memories, avoidance, negative changes in thinking and mood, and changes in physical and emotional reactions. Symptoms can vary
over time or vary from person to person.
