Concussions also have different degrees of severity. According to the Cantu guidelines, concussions have several grading scales: Grades I, II, and III. Grade I concussions are not associated with loss of consciousness, and post-traumatic amnesia is either absent or less than 30 minutes in duration. Athletes may return to play if no symptoms are present for one week. Grade II is a loss of consciousness for less than five minutes or exhibit post-traumatic amnesia between 30 minutes and 24 hours in duration. They also may return to play after one week of being asymptomatic.Grade III concussions involve post-traumatic amnesia for more than 24 hours or unconsciousness for more than five minutes. Players who sustain this grade of brain injury should be sidelined for at least one month, after which they can return to play if they are asymptomatic for one week.The week begins the day after all symptoms have dissipated.
