Researchers from the University of Birmingham in the U.K. have proposed a breathalyzer test that could detect chemicals present in athletes’ breath that indicate a brain injury. While the breathalyzer to detect concussion has not yet been developed, the researchers hypothesize that if adapted from breathalyzers used to detect alcohol, concussions could be detected within 5–10 minutes of injury for both professional and non-professional athletes. While MRI scanners are the current optimal means of diagnosis of concussion, a breathalyzer could be a convenient and faster means for determining if athletes should return to play or seek medical attention immediately.

The "return to play decision" after a head injury is a serious problem that has caused tragedy and controversy. Among the new proposals is a breath test, which successfully detects key chemicals in early laboratory trials.
