What is traumatic brain injury?

A U.S. Army soldier is accused of killing 16 Afghan men, women and children in a house-to-house shooting rampage on Sunday. He could face the death penalty, Defense Secretary Leon Panetta said.

The shooting has brought traumatic brain injury back into the news. Traumatic brain injury has become one of the signature injuries of the wars in Iraq and Afghanistan.

Dr. Sanjay Gupta, CNN Chief Medical Correspondent, offered an explanation in a past story, which we've reposted here:

It’s called “traumatic brain injury” or TBI. It’s a blow, jolt or penetration to the head that can disrupt the normal functioning of the brain. It can happen anywhere and at anytime – during a fall, car crash or even rough sports. Concussions are a milder form of TBI.

One of the biggest causes are unexpected blasts from improvised explosive devices or IED’s. Their sheer force can literally rock the brain, even when wearing a helmet. The skull strikes a hard surface and the brain goes back and forth, like jello wiggling, and then begins to bruise from the swelling.

It’s important to remember that there’s a broad range of severity for TBI. Common symptoms include headaches, dizziness, sleep disorders, nausea or memory problems. In mild cases, a traumatic brain injury may present as headaches or occasional dizziness. More severe cases can involve complete memory loss, personality changes or even persistent vegetative state.

Today, the Army checks soldiers before and after deployment to identify TBI cases. But unlike an obviously severed limb, traumatic brain injuries are difficult to diagnose, sometimes only noticeable years after leaving the battlefield.

Unfortunately, there is no one way to treat TBI. Recovery depends on the severity of the case and varies from person to person.

Everything from talk therapy to rehabilitation to the use of drugs to reduce symptoms of depression and anxiety are used. The good news is that mild cases often require little more than rest and over-the counter pain reliever.

    The article was lame. I think the article should have explored the ramifications of TBI on behavior and responsibility, and possible ideas on how to deal with some of the victims with severe deficits, and worse those like the Afghan shooter who became a danger to others because of his injury.

      Here's a good resource for information about traumatic brain injuries if you're really interested in finding out more information. They also have a blog with articles, I was just reading one about how a causal link between TBI's and PTSD has been found. I guess that's not surprising necessarily, but it gives you an idea of what these soldiers are forced to endure..

    The article was concise and factual... flip comments aside. TBI, even one, is a bbiiiiaaacchhhaaah, and recovery can be a lifelong struggle for the injured person. Bad tempered family saying like "snap out of it" is equivalent to ranting on a paralyzed person to jump up and run. Just wrecks um worse.

    From a legal standpoint, I don't see why mental illness from TBI needs to be treated differently from any other mental illness, for the purpose of the insanity defense: http://lawblog.legalmatch.com/2012/03/15/people-traumatic-brain-injury-criminally-culpable/

      Rich .. Let me first start by saying thank you for your secivre. Second let me apologize for all those that did not know better. Third I would ask you not to begrudge your fellow vets, as in a fire fight luck is in the draw of the cards or if you believe divine intervention. Any help for any vet should be embraced. While I can understand how speaking your peace may have made you feel better I would almost guarantee if you were to see any of the K9 s make a difference in the life of a fellow vet you would also feel better. I came to this site looking for information to assist other vets with this possibility. I am glad to have found these resources, having read every one of the posts yours was the one I felt compelled to respond to. Again a heart felt thanks to you and all the others who returned and were afraid to wear the uniform of their county. I do find peace in knowing you made a connection with a soul that does not know how to judge.. a K9 Peace be with you Brother.

    TBI is not a mental illness, it's physical damage to the brain.
