Brain injury biomarker levels increase as a result of asymptomatic high-acceleration head impacts

0
Serum levels of two biomarkers of traumatic brain injury (TBI) were found to have increased in American varsity football players following high-acceleration head impacts (HHIs), researchers from the University of Michigan (MI, USA) have revealed.

The study, published in the Journal of Neurosurgery, aimed to determine whether injury to the brain occurs in the absence of clinical symptoms.

The nature of American football makes it difficult to detect whether, and to what extent, brain injury has occurred. Helmet-based accelerators were used by the researchers to measure the head impact data of 16 players across the 2016 football season, during both training sessions and matches.
