Women are more likely to develop PTSD than men, and there is some evidence that susceptibility to the disorder may run in families.

Anyone can get PTSD at any age. This includes war veterans and survivors of physical and sexual assault, abuse, accidents, disasters, and many other serious events.

Not everyone with PTSD has been through a dangerous event. Some people get PTSD after a friend or family member experiences danger or is harmed. The sudden, unexpected death of a loved one can also cause PTSD.

It is important to remember that not everyone who lives through a dangerous event gets PTSD. In fact, most will not get the disorder.

Many factors play a part in whether a person will get PTSD. Some of these are risk factors that make a person more likely to get PTSD. Other factors, called resilience factors, can help reduce the risk of the disorder. Some of these risk and resilience factors are present before the trauma and others become important during and after a traumatic event.

Risk factors for PTSD include:

• Living through dangerous events and traumas
• Having a history of mental illness
  Getting hurt
• Seeing people hurt or killed
  Feeling horror, helplessness, or extreme fear
• Having little or no social support after the event
• Dealing with extra stress after the event, such as loss of a loved one, pain and injury, or loss of a job or home.

Resilience factors that may reduce the risk of PTSD include:

• Seeking out support from other people, such as friends and family
• Finding a support group after a traumatic event
• Feeling good about one’s own actions in the face of danger
• Having a coping strategy, or a way of getting through the bad event & learning from it
• Being able to act and respond effectively despite feeling fear.
