Article discusses the frequency-following response (FFR) a new, objective approach to identify concussions (Hearing Journal. 2017;70[3]:56) and, potentially, brain damage from repeated subconcussive injuries, such as those endured by football players. The FFR is a measure of sound-evoked synchronous neural activity and a sensitive test of brain health. The unique advantage of the FFR is that it requires no behavioral response from patients; patients cannot will their brains to respond in a certain way. Therefore, it can sidestep many of the challenges that current approaches to diagnose concussions face.
