He's a professor from the department of physiology at the Federal University of Juiz de Fora in Brazil.
WEDNESDAY, July 3, 2019 -- Certain high school and college athletes require a longer-than-normal recovery period after a concussion. Researchers say blood tests can predict which ones.
"With so many people sustaining concussions and a sizable number of them having prolonged symptoms and recovery, any tools we can develop to help determine who would be at greater risk of problems would be very beneficial, so these results are a crucial first step," said study author Timothy Meier, of the Medical College of Wisconsin, in Milwaukee.
