Using imaging scans, researchers spotted “microstructural” changes in the white brain matter of 25 male athletes aged 8 to 13 after a season of football.
They also found that players experienced more significant brain changes if they took a greater number of hits and stronger hits to the head, said lead researcher Dr. Christopher Whitlow. He’s chief of neuroradiology at Wake Forest School of Medicine in Winston-Salem, N.C.
“We’re seeing some associations between the amount of change in the brain and the amount of exposure to head impacts,” Whitlow said. “The more exposure they’ve had, the more change you see.”
