The Coast Guard Academy, which is involved in the most comprehensive concussion study to date, is preparing to track cadets after they leave the academy to examine the impact a concussion can have on a person's brain over time.
The study, launched in 2014 by the NCAA and the Department of Defense, initially looked at the impacts from concussions or repeated head injuries in the hours, days and weeks after the injury, and compared those to assessments done beforehand. Now, it is expanding the study to look at potential cumulative effects.
