It’s one of the most life-altering war wounds that a service member can experience, even though it doesn’t leave a scratch on the body: Post-traumatic stress disorder (PTSD) is a severe mental health condition that can take a tremendous lifelong toll on military veterans and their families — as detailed in two recent books from Biola authors.

And after more than a decade of military involvement in the Middle East, the disorder is on the rise. According to a recent study, about 30 percent of the 834,000 Iraq and Afghanistan veterans who accessed VA health care over the past decade were diagnosed with PTSD. Facing the growing needs, the federal government in August launched a new $107 million research effort aimed at better diagnosing and treating PTSD and mild traumatic brain injuries.

What should we know about the disorder, and what can we do to help those whom it affects? To learn more, Biola Magazine connected with alumni Kelly Orr (Ph.D. ᾽78) and Welby O’Brien ('78), each of whom authored books this year on PTSD and military veterans.

A lot of people who are familiar with the term “post-traumatic stress disorder” may not have a good sense of what the condition actually involves. Can you give us an understanding of what life is like for someone with PTSD?

O’BRIEN: PTSD is rampant, rapidly escalating, and most people have no idea of how severely it affects those who have it — young and old, men and women — as well as all those around them who love them. PTSD can affect everyone, not just veterans. As a result of a severe trauma, they will live as if the impending crisis could reoccur at any moment. They live in constant fear. Braced. Adrenaline always switched on. Staying in that emergency mode 24/7 severely overwhelms the person’s ability to cope. When something triggers them — agitates and stirs up the trauma — they have no reserve with which to handle it in a healthy way as others might. Sometimes it takes all they have to just get up in the morning, and to just make it through the day.

What are some of the most common symptoms or behaviors associated with PTSD?

ORR: The most common symptoms and behaviors include intrusive thoughts and memories often referred to as flashbacks, emotional numbing, avoidance of reminders of the trauma and hypervigilance. However, equally important to recognize are other symptoms
