Who will get PTSD?

Part 1 of 2

If the day was pleasant, and even when it wasn’t, the two boys would march themselves into the forest, in the shadow of the Black Hills in South Dakota, and hunt. They were no more than 8 at the time, so they took BB guns — all their parents allowed them — and looked for small game, squirrels mostly. The challenge of it turned the boys, Brian Baldwin and his cousin Chuck, into sportsmen and then best friends.

After high school, Chuck went off to Vietnam as a helicopter gunner. Brian started college and joined the ROTC on campus. By the time he got his commission and completed flight school to be a Medevac pilot, the war was almost over.

Nevertheless, Brian’s military career took off: He found that he loved the officer’s life. Chuck, though, struggled. He came home from the war quick to anger, and he drank too much, moved around a lot and watched his marriage dissolve. When Brian saw him around the holidays, Chuck would want to talk about the war. Brian always switched the subject.

One night in the 1980s in his home in Rapid City, S.D., Chuck drank too much again. Only this time, before he passed out, he pointed a gun at himself. When he pulled the trigger, he left behind a second wife and a young son — just a few years removed from his first hunting trip.

Post-traumatic stress disorder soon entered the public lexicon. What haunted Brian were the signs he missed. He wished he’d pulled more bottles away from Chuck or talked with him when he wanted to discuss the war. Chuck was isolated back in South Dakota, Brian realized, with no one around him who knew the military, the images he’d seen.

Brian never forgot that. In 1998, after 25 years, Brian retired from the Army. He ultimately took a job as a project manager at the University of Texas Imaging Research Center, which scanned the brains of people who suffered from PTSD. “I wanted to make up for my own failings,” he says.

He wanted to know why Chuck could be affected by Vietnam in ways other vets weren’t. He wanted to know, in short, if it would be clinically possible to predict who would develop PTSD.

He met with Michael Telch, a professor of psychology at the school. Telch was intrigued by Brian’s idea but knew its limitations. It wasn’t easy to do a before-and-after study of trauma. In the civilian population, it was impossible to guess when a person would live through something traumatic. In the military, some leaders didn’t even believe in PTSD; the last thing they wanted were civilian academics questioning soldiers.

The wars in Iraq and Afghanistan changed that. Or rather, the veterans returning from those wars and the nearly one in five Vietnam vets who had suffered, or still suffered, from PTSD provided irrefutable proof that the military needed to look for ways to treat the condition.

Brian had spent part of his career at nearby Fort Hood, and in 2007 he and Telch approached Army leaders at the base about a study. Telch wanted to put soldiers through a battery of tests before they deployed, have them fill out online journals during their tour, and then follow them for a time after they had returned to the States.

Fort Hood agreed. Telch ran his tests and, once the soldiers had come home and he could analyze his results, found something intriguing: If soldiers exhibited certain physical and emotional characteristics before deployment, they were more likely to suffer from PTSD after it. As Brian Baldwin would have hoped, it appears as though PTSD can be predicted.

Telch’s work is part of a provocative new strand of PTSD research, using modern psychology and computer science to unlock why and when a traumatic experience can derail a life. These studies — not just in military but civilian populations, too, testing cops and other first responders — hold the potential to transform our understanding of PTSD, changing it from an enigmatic and disruptive affliction that crashes over some people but not others, to a condition that can actually be predicted, quantified and prepared for.

While it sounds promising, the new research also raises ethical questions: If it becomes possible to screen enlistees for their vulnerability to PTSD, is it fair to keep some out of combat and send in others, especially in an all-volunteer military where every solider has raised his or her hand to take the same risks? If you send these potentially troubled enlistees to war anyway, what is your liability for any harm they do to themselves afterward? Or to others?

Telch says he and his researchers have measured soldiers “in all sorts of things that haven’t really been looked at in a prospective study.”

Even if a test is developed, some PTSD experts question whether we should screen soldiers at all. To do so could create the impression that battle trauma is something orderly, even manageable, when war itself is chaos and the consequences of facing combat uncontrollable. To screen soldiers for PTSD, some experts believe, is to pretend war is something it’s not.

PTSD may be a relatively new phrase, but the problem it describes is as old as any history of war. In The Iliad, for instance, after the great warrior Achilles hears that a friend has died while fighting in his place, he scoops dirt into his hands and pours it over his body; he pulls out his hair; he says, “Nothing matters to me now.” In a rage, he finds Hector, the man who killed his friend, and spears him through the neck. He then ties the body to his chariot and drags the corpse through the streets. What Achilles endures — the torture of knowing that his life came at the expense of his friend’s death — is “also the story of many combat veterans, from Vietnam and other long wars,” writes Jonathan Shay, a former psychiatrist at Boston’s Department of Veteran Affairs Outpatient Clinic, who won a MacArthur Fellowship in 2007 for examining psychological trauma in The Iliad and The Odyssey.

Though it may not have gone by the name PTSD, other cultures in other times have acknowledged it and tried to treat it. Many Native American tribes, for instance, held initiation ceremonies for warriors at every stage of their lives, says Edward Tick, a clinical psychotherapist who is training Army chaplains in dealing with PTSD. “In Lakota tribes,” Tick says, “PTSD was called something that meant ‘The spirits left him.’” The tribe comforted the warrior for days or weeks and held a ceremony when they felt he had regained his equilibrium.

Russia is seen as the first modern society to treat psychological wounds. In the Russo-Japanese War of 1904 and 1905, Russian military personnel placed civilian psychiatrists near the front lines, to treat the soldiers who had developed “shell shock,” according to Richard A. Gabriel’s book No More Heroes: Madness and Psychiatry in War. The Russian psychiatrists confirmed much of what the Lakota had intuited: It was best for the soldiers to rehabilitate not in isolation but amid others, almost always from their warrior class. The psychiatrists talked with these soldiers near the front, for days or weeks if necessary. Many Russian soldiers then rejoined their units, Gabriel writes. (Americans began using such forward treatment, as Gabriel describes it, at the end of World War II, and it remains common today.)

When it comes to the modern science of PTSD, research has only recently asked the more basic question of why it happens and to whom and when. Charles Marmar, a psychology professor at New York University, has followed police officers from the academy through their first years on the streets, trying to determine whether some cops are at increased risk of developing PTSD. So far Marmar has found that officers who experienced childhood trauma, or hold a negative view of the world, or have only a few years on the force, are more likely to develop PTSD. (He also found no correlation between PTSD and intelligence.)

Who will get PTSD?

Part 2 of 2

Dewleen Baker, a professor at the University of California-San Diego and psychiatrist at the VA San Diego Healthcare System, is overseeing a longitudinal study with over 2,000 Marines, studying them from prior to their deployment until well after it, and looking among other things to identify the specific kinds of experiences that might cause PTSD.

Telch, among researchers who focus on the military, has pushed furthest toward the possibility of predicting whom PTSD might strike. With Brian Baldwin’s assistance and Fort Hood’s blessing, Telch had roughly 160 soldiers submit to a battery of tests at the University of Texas before the soldiers headed to Iraq. “We made sure that … they’d never been deployed to a war zone before,” Telch says, the better to establish a baseline of experience. Once they were in country, the soldiers filled out an online log every month of the stressors they’d faced and any psychological reactions they’d had to them. Once the soldiers had returned to the States, Telch and his staff monitored them for a year.

Perhaps the biggest insight came from the eye-tracking test. Before deployment, Telch asked soldiers to look at a panel of four faces while a computer monitored the soldiers’ eye movements. In the panel the soldiers saw a happy face, a sad face, a fearful face and a neutral face. The soldiers who quickly averted their gaze from the fearful face — looked away within 100 milliseconds of seeing the photo — were far more likely to develop PTSD after deployment, the study found. These soldiers needed only half as many war-zone stressors as other soldiers to develop symptoms associated with PTSD, the study found. The research was published last year in the American Journal of Psychiatry.

In total, Telch and his colleagues have published five studies on the Fort Hood soldiers and PTSD, with a sixth forthcoming. They measured the soldiers “in all sorts of things that haven’t really been looked at in a prospective study,” he says. The researchers have looked at what happens to cortisol levels when soldiers with high testosterone feel threatened. (The levels shoot up, indicating stress.) They’ve tested soldiers’ panic response, by having them inhale oxygen laced with 35 percent carbon dioxide; those who lose their nerve appear to be more likely to develop PTSD.

Dr. Jennifer Vasterling, the chief of psychology at the VA Boston Healthcare System and a researcher at the National Center for PTSD, says Telch’s work has “a unique place” in the study of the disorder. A few researchers have conducted a handful of before-and-after studies on PTSD in the military, she says, but never one with numerous real-time readings of a soldier’s psychological state.

Telch says his preliminary results are just that. He would like to know what other physical or mental characteristics might lead to an increased risk of PTSD — as well as conduct further tests on the characteristics he’s already singled out. Predicting PTSD is a new idea, he says, and it will take time to say conclusively which soldiers under what circumstances are likely to develop the disorder. “Do our studies have any implications for prevention?” Telch asks. “Definitely.”

As many as 20 percent of Iraq and Afghanistan veterans have PTSD or will develop it, the VA estimates. So what will the military do with Telch’s studies? Officials at the Department of Defense did not return requests for comment for this story, and Fort Hood officials declined to comment. Telch says he is not trying to develop a formal screening test himself; he says that would fall to the military.

It’s already clear what issues might arise as doctors get better at predicting who is more susceptible to psychological trauma. One is simple fairness. Is it fair to keep soldiers off the front based on a test that assigns them a higher percentage chance of developing PTSD?

Gen. Barry McCaffrey is a retired four-star general and an advocate for veterans battling drug and alcohol addictions. When asked if the military should filter out soldiers likely to develop PTSD, McCaffrey says without hesitation, “I think the answer is yes.” Some of these wounds can last a lifetime — or end a life.

McCaffrey also acknowledges that the military would quickly run into practical limitations: It is a force composed of volunteers, and the military has had to lower its recruiting standards simply to find enough men and women to fight in Iraq and Afghanistan. Many soldiers have endured multiple tours. Rigorous screening may not be practical; the military needs the recruits it gets.

It may also be harder to apply than it might first seem. To assume that some soldiers should go to the front while others drink tea with the locals misconstrues modern warfare, McCaffrey and other military experts say. There isn’t necessarily a front that you can keep soldiers away from: There are only urban streets, desolate villages, some familiar faces and a lot of uncertainty. The threat of a battle is everywhere and nowhere.

This underlies another problem that some experts have with screening soldiers for PTSD: the notion that traumatic events can somehow be contained. Tick worries that any successful predictive test could lull the military into seeing PTSD as a solvable problem, more like a preventable disease than an inevitable, if random, consequence of seeing combat. “That’s dangerous,” he says.

The best approach, he argues, is for the military to assume that some people will always be haunted by the experiences they endure, and that it is in fact normal for this to happen. The psychic impact of war isn’t so much a disorder, or a sign of some pre-existing weakness, as a battle injury — one that underscores the valor, and hardship, of what we ask of people when we send them to war.

“Combat hurts,” Tick says. “And it should hurt. [The military] can’t go looking for a silver bullet.”

Interesting study.

[neecheepure]

Interesting, and with some far-reaching implications. I'd like to see some research based on this study that begins changing gears toward prev-med for those deemed more susceptible.

[Inflexible Six]

This research seems to have more validity than some of the other studies publicised in recent years.

[mugwump]

There is a slew of research in process that is correlating PTSD with TBI as well. It's likely that a significant fraction of PTSD may be physical in origin--traumatic brain injury that is currenty sub-clinical.

[Inflexible Six]

I wonder if studies pay enough attention to the stress of transition for combat veterans who leave the military and enter the civilian workforce?

Consider being with a group of guys who'd risk their life for you, and for whom you would risk yours, where trust is a matter of life and death...and then you find yourself in an environment where nobody trusts each other, where everybody's out to screw each other, where your military record means nothing. To them, it's an ancient history they'll never understand. They don't care if you ran through enemy fire to facilitate the evac of a wounded comrade, they only care how much of a threat you are going to be to their job security. When you bust your ass and do a great job in the civilian workplace you're not going to get a tab or a badge or a chevron or a hashmark or a commendation...and chances are even if you ask for a raise you won't get one. And you have a boss, a guy who maybe would've lasted a a week or two in basic or bootcamp before getting sh*tcanned--if the idea of serving his country had ever crossed his mind (and it hasn't) and he rides you just like he rides everybody else.

It's the exacerbation of PTSD I'm talking about.

I understand where you are saying, Six, and the downside is this situation might appear to be as described and be quite overwhelming to someone already coping with PTSD, however these are the same people we defended when in uniform. Fortunately there are many veterans out there and in the work force so one is not 100% alienated, IMO.

The experiences and training we come away with, IMO, gives us a one up over many of our contemporaries that we may share work space or occupational duties with. Their lives have significant value, if not to us as co-workers and former combat veterans, then to their friends and families regardless of what kind of person they might be on the job. We might still have their backs, if that is what we choose, all the while nobody has ours.

Has anyone ever seen "The Best Years of Our Lives"? PTSD has been with us a while. I think the reaction of society has a lot to do with it.

Yes, it's a great movie and it nails that feeling of isolation, of being alone in a crowd that combat vets sometimes experience in the civilian world. What you have done, what you have seen and smelled and felt is something most people can't even imagine. The solace you find is often only in the company of other combat vets. The average civilian idea of a critical issue is a work deadline or a meeting with the boss. Your idea is an ambush or a priority medevac. Nowadays people mean well, supporting the troops, taking the time to thank you for your service, and that's important...but it's still impossible for them to relate. I think men who stay in the military have an advantage over those who don't. Their PTSD issues--if they have them (and I think most people who seen considerable combat or who have suffered serious wounds have it to some degree), are mitigated somewhat by their daily association with fellow combat vets and brothers. The support structure is there.

(FYI, there's another movie called "The Razor's Edge" that Bill Murray starred in that deals quite well this subject.)

Agreed. Every war has had people with what is clincally called PTSD today. Societal values/norms for the previous generations expected combat veterans to "get over it and move on" as my grandfather (Korean War vet) used to say. On an ancillary note, I get the feeling that there are quite a few people who are using the system on the PTSD front. I know there are legitimate cases, but the diagnosis criteria is susceptible to manipulation, similar to how parents are manipulating the autism spectrum disorder for their children. I've met one too many people who sat in a tent far away (i.e., support at places like Bagram) from any combat related activity and have gotten a PTSD diagnosis. I even served with one of these individuals in A-stan in 2002/2003, and the most traumatic experience he experienced was the power going out while he played video games. These are typically college age males. I do agree that the longitudinal study is a good idea, but it seems that PTSD is so multi-factored that it will be extremely difficult to come up with a predictive matrix.

Absolutely. And most of them should read up on it before faking what they think are the symptoms. Some REMF/Fobbit/POGs are pretty good at balling for cash at the VA because they saw some tracer rounds arc up into the sky from a klick away.

Those emotions highlighted in The Best Years of Our Lives, the sense that you have changed and the world has not, the feeling that you no longer fit in, may not be a "disorder" at all. I think its perfectly normal for men who've been in combat fairly routinely to feel, once they return to the trivial world, that they don't belong there. Combat is a character-building experience. It matures you in many ways, it makes you different. It also makes you a lot less willing to put up with disrespect and petty bullshit. Is that part of PTSD? I don't know.

[booker]

Hell, I feel like I don't belong in general society, and I think that most of the people on this board are in the same boat. Maybe we all have PTSD... I think that you hit the nail on the head Six.

The above has been my general opinion, or was. I have a younger friend (diagnosed DS vet, career NCO) for whom that was the culminating "event" in their career. Taking the question a bit further, is it perhaps less-related to career vs. one-termer and more to "how soon post-event is the individual dumped from the support structure you describe?

The behaviors you describe are seen by me in the aforementioned friend. The intolerance for the petty bullshit is on their sleeve, which leads to acting out (as viewed by those who take pains to wrap themselves in the cloak of civility). The other issue I hear is that the burden or flaw, and the resentment, is directed inward. It's not, "these civilians don't understand me" but rather, "I just can't understand these civilians."

By the way, in the handful of such folks I know, the number one thing, in day to day living, that seems to get a fist bashing the table and the blue words filling the air is people not keeping their word, or a promise, or an appointment. Come to think about it, I guess that's me in a mirror too sometimes...

All valid points. If it were up to me, I'd come up with a new name for the issues we've been discussing, because I don't think that partuclar aspect that we've been discussing is PTSD. I think is much more universal and common for a returning warfighter to feel that he is now different, especially among his civilian friends and aquaintances.
