A practicing sports concussion neuropsychologist and leading researcher, Dr. Rosemarie Moser, explains in an important SmartTeams Talk why it is so important for student-athletes to get cognitive rest after a concussion, what cognitive rest means, and why she urges athletes to "love their brain, love their sport" by delaying a return to sports for around 3 weeks after their concussion symptoms are gone and do not return with exercise and they are off all academic accommodations.
