Post-Traumatic Stress Disorder (PTSD)

Understanding PTSD

Post-traumatic stress disorder, or PTSD, is a serious potentially debilitating condition that can occur in people who have experienced or witnessed a traumatic event, such as a natural disaster, serious accident, terrorist incident, sudden death of a loved one, war, violent personal assault such as rape, or other life-threatening events. There are currently about 12 million people in the United States living with PTSD and that is only a small portion of those who have gone through a traumatic event.



It’s not unusual for people who have experienced traumatic events to have flashbacks, nightmares, or intrusive memories when something terrible happens — like the 9/11 terrorist attacks and those in cities around the world (London and Paris, for example) or the bombings at the 2013 Boston Marathon, or active combat. 


Be tolerant of your nervous system: it’s having a normal reaction. Try not to get hooked on news reports, which may seem particularly compelling. Spend time with loved ones, in favorite activities or outside in nature, and avoid alcohol.


But if these symptoms persist over months or years or cause you to drop into deep depression or anxiety, it is possible you have developed PTSD. You can take a self-screening test to help you find out if your feelings and behaviors may be related to PTSD, but keep in mind that only a trained provider can diagnose PTSD.


Thankfully, there are treatments available that will help. Learn more below about statistics, treatments, and resources for PTSD.


Many people experience a traumatic event at some point in their lives, the National Center for PTSD found that about 6 of every 10 men (or 60%) and 5 of every 10 women (or 50%) experience at least one trauma in their lives1. It's typical for those people to recover from that event over time, but people who develop PTSD continue to be severely depressed and anxious for months or even years following the event. And PTSD often occurs with depression, substance abuse, or other anxiety disorders. (The following statistics are based on the U.S. population):



  • About 6 out of every 100 people (or 6% of the population) will have PTSD at some point in their lives.
  • About 12 million adults in the U.S. have PTSD during a given year. This is only a small portion of those who have gone through a trauma.
  • About 8 of every 100 women (or 8%) develop PTSD sometime in their lives compared with about 4 of every 100 men (or 4%).
  • Women are 2x more likely to develop PTSD than men, and children can also develop PTSD

Children and Teens:

  • 15% to 43% of girls and 14% to 43% of boys go through at least one trauma
  • Of those children and teens who have had a trauma, 3% to 15% of girls and 1% to 6% of boys develop PTSD



PTSD does not solely affect deployed, active duty military officers. PTSD can affect any unit of special forces such as first responders, the National Guard, or police forces. These statistics are specifically of PTSD in Iraq and Afghanistan Veterans. 10.9% of non-deployed officers and 15.7% of deployed officers develop PTSD2. Access the full range of data about veterans and PTSD here.


Trauma survivors who have PTSD may have trouble with their close family relationships or friendships. Their symptoms can cause problems with trust, closeness, communication, and problem-solving, which may affect the way the survivor acts with others. In turn, the way a loved one responds to him or her affects the trauma survivor. A circular pattern may develop that could harm relationships. Read more from the National Center for PTSD
