Age, sex, and genetics influence both risk of sports-related concussion and speed of recovery. Women are at higher risk and tend to have more severe concussions. Younger (i.e. high school) athletes recover more slowly than older. The apolipoprotein E ?4 allele has been associated with both increased concussion risk and worse outcome. The majority of patients with a first-time sports-related concussion recover within 7 to 10 days, with 80% fully recovered within three weeks. Post-traumatic headache and the presence of cognitive symptoms predict a slower recovery. History of previous concussion increases an individual's risk of a subsequent concussion.
