Reports indicate that some 300,000 sports-related traumatic brain injuries (TBIs) occur annually in the United States. Athletes involved in sports such as football, hockey and boxing are at significant risk of TBI due to the high level of contact inherent in these sports. Head injuries are also extremely common in sports such as cycling, baseball, basketball, and skateboarding. Unfortunately, many sports head injuries lead to permanent brain damage or worse. TBI, is the leading cause of death in sports-related accidents. Any failure to identify and treat TBIs is especially harmful to younger individuals, as brain tissue is not fully developed in the brains of adolescents. Head injuries sustained among high school athletes often lead to detrimental damage. Injuries experienced at this stage of development can cause longer-lived symptoms and create vulnerability to further damage if another injury occurs. Other symptoms can include significant decline in school performance, worsening of ADHD symptoms, mood disorders, and impulsive and violent behaviors.
