A concussion, a type of brain injury, may occur as a result of hitting the head, such as due to an accident or during a sports game. The symptoms of a concussion vary but often include a headache, falling unconscious, loss of memory, and confusion. The person may slur his or her speech after the incident or report symptoms such as nausea and ringing in the ears.
Although many of the effects of a concussion become apparent immediately, others, such as trouble sleeping and changes in personality, can occur during the days afterward. These aftereffects are especially common in individuals who have experienced more than one concussion. In children not old enough to verbalize well, these aftereffects might include crying, listlessness, and an unsteady appearance while walking.
Children suspected to have a concussion should get medical attention right away. They require plenty of recovery time, during which they should physically rest and take a break from cognitive tasks. A return to normal activities should happen gradually, especially a return to sports, which should not happen until a medical professional gives the go-ahead.
