NEWS FLASH: Brain injury in high-def with fiber tracking

Amazing – this could be the break we’ve been looking for, in getting people to take TBI/concussion seriously.

U. PITTSBURGH (US) — New imaging technology will allow doctors to clearly see for the first time neural connections broken by traumatic brain injury.

“Until now, we have had no objective way of identifying how the injury damaged the patient’s brain tissue, predicting how the patient would fare, or planning rehabilitation to maximize the recovery.”

HDFT might be able to provide those answers, says co-senior author Walter Schneider, professor of psychology, who led the team that developed the technology.

Data from sophisticated MRI scanners is processed through computer algorithms to reveal the wiring of the brain in vivid detail and to pinpoint breaks in the cables, called fiber tracts. Each tract contains millions of neuronal connections.

“In our experiments, HDFT has been able to identify disruptions in neural pathways with a clarity that no other method can see,” Schneider says. “With it, we can virtually dissect 40 major fiber tracts in the brain to find damaged areas and quantify the proportion of fibers lost relative to the uninjured side of the brain or to the brains of healthy individuals. Now, we can clearly see breaks and identify which parts of the brain have lost connections.”

I am a long-term multiple (mild) Traumatic Brain Injury (mTBI or TBI) survivor who experienced assaults, falls, car accidents, sports-related injuries in the 1960s, '70s, '80s, and '90s. My last mild TBI was in 2004, but it was definitely the worst of the lot. I never received medical treatment for my injuries, some of which were sports injuries (and you have to get back in the game!), but I have been living very successfully with cognitive/behavioral (social, emotional, functional) symptoms and complications since I was a young kid. I’ve done it so well, in fact, that virtually nobody knows that I sustained those injuries… and the folks who do know, haven’t fully realized just how it’s impacted my life. It has impacted my life, however. In serious and debilitating ways. I’m coming out from behind the shields I’ve put up, in hopes of successfully addressing my own (invisible) challenges and helping others to see that sustaining a TBI is not the end of the world, and they can, in fact, live happy, fulfilled, productive lives in spite of it all.

  1. Well, I think with all the concussion awareness that’s being raised, along with all the concern in youth sports, parents and coaches/trainers who have a vested interest in finding out just *how* concussed an athlete may be, could conceivably push for more adoption of this method. I would expect it to be cost-prohibitive for most at the start, but as wider adoption takes hold and economies of scale kick in, it might be accessible in, say 5-10 years? Just guessing. Can’t come too soon.
