Sports-related concussions (SRC) account for a large portion of mild traumatic brain injuries (mTBI), with almost half of the reported SRCs occurring in children and adolescents younger than 19 years. While for many years, incidence rates were increasing across all populations, ED visits among children for sports and recreation-related TBI have started to decrease in the past 10 years. In the pediatric population, the rate of concussion increases with age. When comparing high school versus collegiate athletes, collegiate athletes have a higher concussion rate. Risks for concussion in athletes include history of previous concussion and playing on multiple sports teams. Concussions are more common in contact sports compared to noncontact sports and recreational activities. Rugby is classified globally as the sport with the highest concussion rate, while American football leads in concussion rates in the United States. In gender-comparable sports, females experience the highest concussion rate. Sports-related concussions (SRC) are more likely to happen in games as opposed to practice. Majority of concussions are sustained during the regular season as opposed to pre- or post-season. In the National Football League (NFL), SRC rates have decreased since the implementation of a new rule known as “article 8.” For Adults, falls and accidents account for the majority of concussions. Comorbid neuropsychological conditions such as depression, anxiety, PTSD, attention deficit hyperactivity disorder (ADHD), or being under the influence of alcohol may obscure the diagnosis and recovery of concussions. For military personnel, the majority of traumatic brain injuries in deployed and non-deployed settings are mTBI. The current national statistics underestimate the true burden of concussions in the United States because they are based on emergency department/inpatient surveillance data. It does not account for patients treated in outpatient settings or those who fail to seek medical care. The CDC will be implementing the National Concussion Surveillance System (NCSS) in an effort to improve underreporting of concussions.
