Young athletes are at an increased risk of concussion, according to studies at the US National Library of Medicine.
According to the research, sports-related concussions are responsible for about nine percent of all high school athletic injuries. Of all emergency room concussion cases, sports injuries account for 25 percent. These injuries are likely underreported. One 2006 study suggested that 85 percent of concussions in 16-to-34-year-olds are linked to sports.
Concussions occur when a sudden blow slams the brain against the inside of the skull.
Even minor concussions can produce harmful effects, including nausea, loss of consciousness, headaches, irritability, loss of coordination, disorientation, and slurred speech. Severe cases can lead to bleeding in the brain, which can be fatal, and in all instances, symptoms can continue for days, weeks, or even months after the initial event. Anyone with a suspected concussion should see a doctor as early as possible.
