New MRI method aids long-term concussion prognosis
In their new study, published online January 13, 2017 in the Journal of Neurotrauma, the researchers used a technique called functional MRI (fMRI), coupled with sophisticated statistical analysis, to track activity in the brain networks of 75 patients, aged 18 to 55, within the first two weeks of their having experienced concussions.

The study revealed telltale patterns of brain activity that, six months later, were associated with worse performance on behavioral and cognitive tests and were different from patterns seen in healthy control subjects.

The fMRI method and analysis developed for the study highlighted abnormal patterns of brain activity that pointed to a higher risk for long-term, post-concussive symptoms, even among the 44 study participants who had no evidence of bleeding or bruising in the brain in the immediate aftermath of brain trauma on computed tomography (CT) or ordinary MRI scans.
