Mild Traumatic Brain Injury May Cause Cognitive Problems

In these DTI scans, the bottom row shows views of a head with the top sliced away to reveal the brain. The top row shows the corresponding top views of the brain. The green lines represent the white matter— the brain’s “wiring.” The blue areas are the damaged parts of the white matter that seem to be responsible for cognitive problems experienced by study patients with mild traumatic brain injury.

While much is known about the effects of severe traumatic brain injuries (TBI), less attention has been paid to mild and moderate brain injuries.

In a new study published in Neurology, researchers have found that mild TBI may impact patients’ cognition and brain matter.

“The [study’s] focus was really on the mild end… because they’re by far the biggest group of patients when looking at TBI breakdowns— 90 percent of patients have mild to moderate injuries,” study author Andrew Blamire, a professor of magnetic resonance physics at Newcastle University in the United Kingdom, told FoxNews.com. “In terms of trying to understand what happens to the brain immediately after injury, many of these individuals will have cognitive problems… there’s no way of working out which of these will have ongoing problems.”
