High Tech Scan to Detect Brain Injury in Soldiers

posted by SK Brain Injury    |   June 6, 2011 08:46

An experimental high-tech brain scan is finding previously undetected traumatic brain injury in servicemen who sustain concussions in combat.

The research is considered a first step toward a better understanding of what happens in the brain after bomb blasts and what might be done about it, said Dr. David Brody of Washington University in St. Louis. He's senior author of the study in the June 2 issue of the New England Journal of Medicine.

Blast-related traumatic brain injuries have affected about 320,000 U.S. troops and are considered the "signature" injury of the wars in Iraq and Afghanistan, HealthDay reported. But because concussions alone cause no visible damage, experts have debated whether they actually damaged the brain.

The new "diffusion tensor imaging" scans seem to suggest that concussions can affect the "wiring" that connects parts of the brain. It's unclear what the new finding suggests for treatment, Brody said. Scientists are studying whether they reveal anything about a patient's future course, such as the risk of post-traumatic stress disorder.

The scans were done by adding software to an ordinary MRI machine.

The results suggest doctors may someday be able to use objective markers to help make a concussion diagnosis, said Katherine Helmick, deputy director for traumatic brain injury at the federally funded Defense Centers of Excellence for Psychological Health and Traumatic Brain Injury.

Little can be done to reverse the initial brain damage that results from traumatic brain injury, which can cause changes in mood, behavior. But patients can often be helped with physical and occupational therapy and other forms of treatment.
