Rotman study investigates why patients with traumatic brain injury complain of "mental fatigue," even when they make good recoveries
Posted by Patricia Van Roon on 09/16/08
Former Rotman graduate student Dr. Gary Turner, with Rotman senior scientist Dr. Brian Levine, discovered that patients recovered from significant traumatic brain injuries show altered neural responses during the performance of complex tasks. Even though the patients were free of large brain lesions and and could perform the tasks at a level similar to non-injured adults, they showed increased brain activation in the frontal regions, suggesting that their brains work harder to achieve the same results.This study, reported in the November 9, 2008 issue of Neurology, received media attention from MSNBC.com, Yahoo, USNews.com, and Science Daily.
