TBI - Traumatic Brain Injuries

Article contends mild brain injuries among troops are overdiagnosed

ATLANTA — Mild brain injuries — once considered an under-recognized problem in returning military troops — are being overdiagnosed because the government is using soft criteria instead of hard medical evidence, an Army doctor and two other officials contend.

The three are taking aim at Department of Veterans Affairs’ rule for treating such veterans and determining disability pay. They want to call many mild cases “concussions” rather than “brain injuries.” They say the latter implies an ongoing, incompletely healed problem rather than a temporary one that’s in the past.

However, some scientists who study brain injuries dispute that assertion.

According to the trio, here’s the problem: The questionnaire asks whether the person became dazed or confused at the time of an injury or blast, and it attributes such symptoms to concussion.

But a soldier can become dazed from stress, lack of sleep, the confusion of war, or other causes, they argue. In fact, Dr. Charles Hoge, a top Army psychiatrist, published a study last year in the New England journal showing that many brain injury symptoms were actually due to post-traumatic stress syndrome, or PTSD.

The Rand study said some troops may incorrectly blame their problems on head injuries.

“I think it’s fair to say there’s overdiagnosis of concussions going on,” said Hoge. He’s one of three authors of an article published in Thursday’s New England Journal of Medicine.

Trained doctors should be able to sort out the cause of symptoms. But Hoge and his colleagues argue that a concussion diagnosis can still occur, because of subjectivity and the fuzzy concussion definition.

“The problem is we’re attempting to measure concussion many months after injury,” said Hoge, director of psychiatry and neuroscience at the Walter Reed Army Institute of Research in Silver Spring, Md. He wrote the article with Herb Goldberg, a communications specialist at Walter Reed, and Carl Castro, a psychologist at the U.S. Army Medical Research and Materiel Command at Fort Detrick, Md.

The questionnaire should be revised and questions should be asked closer to the time of the incident, the authors said, and the military should refine its definition of concussion. They feel “concussion” better reflects the mild nature of the injury and promotes an expectation of recovery.

“It’s a very, very, very mild physical injury” that often doesn’t need medical treatment, Castro said.

Some veterans groups applaud efforts to better diagnose traumatic brain injuries, but say it’s more likely that the military has been undertreating the problem.

“It stretches credulity to believe that all the people who have suffered traumatic brain injuries in Iraq and Afghanistan are getting the treatment they need. That’s a laughable notion,” said Jason Forrester, director of policy at Veterans for America, an advocacy group.

The military defines a concussion — or mild traumatic brain injury — as a blow or jolt to the head that caused loss of consciousness, altered consciousness or amnesia.

More than 300,000 U.S. veterans of the wars in Afghanistan and Iraq have suffered head injuries, many of them concussions that have gone untreated, according to a Rand Corp. study released last year.

Part of that estimate stems from a questionnaire given to servicemembers as they finish their deployment, which may be months after a blow or jolt occurred, Hoge and his colleagues wrote. Servicemembers can’t always get a thorough medical assessment on the battlefield.

Treatment of mild traumatic brain injuries can cost up to $32,000 per case, the Rand report said. But if the diagnosis is wrong, patients are exposed to drug side effects and other risks, according to Hoge.

VA officials issued a statement this week saying they are proud of their efforts to treat traumatic brain injuries. Forrester, the veterans advocate, said estimates of concussions are probably low because some servicemembers fear that being diagnosed with a neurological or psychological problem would hamper a military career.

I did an internship for a company that was developing a blood test to try to attempt to determine mild to moderate traumatic brain injury. After doing phone interviews with numerous doctors the conclusion I came to was that even the best and the brightest have a VERY difficult time determining the difference between a concussion and mild TBI. Almost all said that they would be on board with a product that could help them to distinguish the difference between the two (provided medical evidence, etc)

Just my two cents.. :)

Lady, your blog and your posts bring things to our attention that are much needed!!
I love the part about soldier's not wanting to be treated for these conditions because tey fear that it may hinder their priceless work. Now that's just honor and bravery at it's finest, no?

Steady On

Good article, I'm going to pass it on to some Veterans I know.

Thank you for once again bringing these things to our attention.
Have a wonderful weekend.

The VA probably could use a revamping, reorganizing, more staffing among other things. I do not believe in any way are they capable of handling so many veterans in the way they should be. DOD dollars should be sent their way and NOW. Delay is not an option.

Great post!

debbie...I do agree, there is room for improvement in the VA ...but thank goodness we have such an organization.
