Posttraumatic Stress Disorder Risks

When an individual experiences, witnesses, or even learns about an extremely frightening event or ordeal (especially one involving death, terrible injury, or sexual abuse), they have an increased PTSD risk.
Terrible experiences lead individuals to experience intense horror, a sense of helplessness, and intense fear: their “fight or flight” response is activated, but then usually goes away after the event is over.

What Causes Some People And Not Others To Develop PTSD?

While most people readjust to normal life after a terrible event, some find that their feelings of horror, fear, and helplessness worsen with time: their “fight or flight” response has malfunctioned and continues to wreak mental and emotional havoc for months or years after the event is over.

Traumatic Events Increasing PTSD Risks

These events can cause an individual to have increased Posttraumatic Stress Disorder risks:

  • Physical attack
  • Active-duty combat
  • Child abuse and/or child neglect
  • Sexual abuse or assault
  • Extreme life events (for example: car accidents, house fires, or medical emergencies)


PTSD is a mental health issue that affects different people in different ways. People of any age—even children—are at risk for PTSD. While experts are not sure exactly what causes PTSD in some people and not in others, some of these Posttraumatic Stress Disorder risks can be attributed to:

  • How an individual’s brain controls hormones and chemicals in stressful situations
  • Inherited risks of depression or anxiety
  • The temperament or personality of an individual
  • The level of severe trauma experienced during and since early childhood
  • Family instability, lack of a social support system, or poverty
  • Women are twice as likely to develop PTSD than men
  • Having a pre-existing emotional or mental health disorder, eating disorder, or drug/alcohol abuse
  • Sleep disorders such as insomnia or sleep apnea
