A protein in the central nervous system could provide a useful tool for diagnosing concussions and allow doctors to assess when it is safe for athletes to return to competition.
Swedish researchers have found, through examining studies in sporting injuries, that a protein in the central nervous system could provide a tool for diagnosing concussions. They published their results in JAMA Neurology.
Previous studies have measured changes in the levels of protein biomarkers present in cerebrospinal fluid or blood in athletes who participate in contact sports.
Certain biomarkers - neuron-specific enolase, S-100 calcium-binding protein B, neurofilament light and total tau (T-tau) - have been shown to increase in boxers, correlating with the number and severity of head blows received. After a rest from boxing, these biomarkers return to normal levels.
