MRI Can Locate Brain Damage Following Concussion

Scientists are able to locate damaged white matter in the brain in people who experience symptoms of concussion, according to a report published in Radiology by the Radiological Society of North America.

Researchers used magnetic resonance imaging (MRI) to identify regions where there is white matter damage in people who suffer from chronic dizziness and other symptoms that develop after a concussion. One of the most common effects of concussion is vestibulopathy, which refers to the condition characterized by dizziness, imbalance, and visual problems. Until now, there has not been a specific region in the brain that is linked to vestibulopathy.

This study involved the review of imaging data from patients with vestibular symptoms after concussion. The researchers used MRI and found that there was white matter damage in the cerebellar area, which is known to control balance and movement, and also in the fusiform gyri, an area that intergrates the visual fields of each eye. The fusiform gyri is also essential for spatial orientation.

Previously, it was thought that vestibulopathy was associated with the inner ear, but these results identify a region in the brain that appears to be involved with these common symptoms from concussions. This study provides more insight into the complex pathology that is concussion. By studying these regions of the brain, doctors may be able to better diagnose and treat concussions.
