ST. LOUIS (KMOX) – A new Saint Louis University study finds hard evidence that combat-related injuries leave a mark.

Neuropsychologist Dr. Tyler Roskos says veterans who suffered head-related blast injuries have changes in brain tissue that are still apparent in images years after the blast.

“So what we can say is there are some evident differences in the brain structure in these individuals which may account for some of the difficulties that they’re having,” Roskos explains.

Those difficulties include depression, substance abuse, sleep deprivation, and mood changes.

In civilians who suffered mild traumatic brain injury, such as a concussion, cognitive issues were typically resolved within one to three months.

The findings are some of the first to come from a Department of Defense-funded brain imaging grant to Saint Louis University to find out more about the nature of traumatic brain injury.
