Recovering From Frightening Events

It’s natural to be afraid after something scary or dangerous happens. When you feel you’re in danger, your body responds with a rush of chemicals that make you more alert. This is called the “flight or fight” response. It helps us survive life-threatening events.

But the brain’s response to frightening events can also lead to chronic problems. This can include trouble sleeping; feeling on edge frequently; being very easily startled, anxious, or jumpy; having flashbacks; or avoiding things that remind you of the event.

Sometimes these symptoms go away after a few weeks. But sometimes they last much longer. If symptoms last more than a month and become severe enough to interfere with relationships or work, it may be a sign of post-traumatic stress disorder, or PTSD.

“There are real neurobiological consequences of trauma that are associated with PTSD,” explains Dr. Farris Tuma, who oversees the NIH traumatic stress research program. NIH-funded researchers are uncovering the biology behind these brain changes and looking for ways to prevent and treat PTSD.

What is Trauma?

“Most people associate post-traumatic stress symptoms with veterans and combat situations,” says Dr. Amit Etkin, an NIH-funded mental health expert at Stanford University. “However, all sorts of trauma happen during one’s life that can lead to post-traumatic stress disorder and post-traumatic stress disorder-like symptoms.”

This includes people who have been through a physical or sexual assault, abuse, an accident, a disaster, or many other serious events.

Anyone can develop PTSD, at any age. According to the National Center for Post-Traumatic Stress Disorder, about 7 or 8 out of every 100 people will experience PTSD at some point in their lives.

“We don’t have a blood test that would tell you or question you can ask somebody to know if they’re in the highest risk group for developing PTSD,” Tuma says. “But we do know that there are some things that increase risk in general and some things that protect against it.”

Biology of Traumatic Stress

Researchers are looking into what puts people at risk for PTSD. One team, led by Dr. Samuel McLean, a trauma expert at the University of North Carolina, is investigating how post-traumatic stress symptoms develop in the brain. They will be following 5,000 trauma survivors for one year.

“We’re enrolling people who visit trauma centers immediately after a trauma because evidence suggests that a lot of the important biological changes that lead to persistent symptoms happen in the early aftermath of the trauma,” McLean says.

They’re gathering information about life history prior to trauma, identifying post-traumatic symptoms, collecting genetic and other types of biological data, and performing brain scans. The study is also using smart watches and smart phone apps to measure the body’s response to trauma. These tools will help researchers uncover how trauma affects people’s daily lives, such as their activity, sleep, and mood.

“Our goal is that there will be a time when trauma survivors come in for care and receive screening and interventions to prevent PTSD, just in the same way that they would be screened with X-rays to set broken bones,” McLean explains.

Coping With Trauma

How you react when something traumatic happens, and shortly afterward, can help or delay your recovery.
