A team led by researchers at the University of California San Francisco analyze and track activity in the brain networks of 75 concussion patients, aged 18 to 44, within the first two weeks of their injury. Only subjects who had lost consciousness for less than 30 minutes were eligible for the study. Many study subjects never lost consciousness during their injury. Nonetheless, using functional MRI (fMRI) and sophisticated statistical analysis, the researchers by their technique were able to reveal telltale patterns of brain activity that were associated six months later with worse performance on behavioral and cognitive tests and that were different from patterns seen in healthy control subjects. The technique shows that it is possible to identify which brain trauma patients may have more persistent symptoms and guide treatment and patient counseling decisions. Bravo.
