### New Concussion Indicator: The Headshake

A spontaneous headshake following a hit could be a telltale sign of a concussion, according to recent findings. Researchers urge the inclusion of this recognizable movement in official concussion evaluation guidelines to help detect undiagnosed cases.

Characterized as a lateral headshake, this gesture often follows confusion or disorientation—symptoms linked to concussions. The recommendation is based on survey data showing that young athletes associate this movement with head injuries.

Recognizing this as a concussion indicator could aid in identifying nearly a third of undiagnosed cases. Current protocols in sports should consider this sign for player safety, preventing prolonged exposure to potential brain injuries. Furthermore, integrating the headshake into protocols offers a no-cost measure that prioritizes athlete health and safety. By adopting this approach, clinicians and players may better understand and address concussion symptoms.
