Concussion risk factors and strategies for prevention

Concussion in children is frequently related to participation in sports. It requires a traumatic event to occur that transmits acceleration to the brain. Some children may have intrinsic risk factors that place them at greater risk for this type of injury. Comorbidities such as attention-deficit/hyperactivity disorder, migraine headaches, and mood disorders may place athletes at increased risk of more severe injury. A previous concussion is probably the most important influence on risk for future injury. Extrinsic risk factors include coaching techniques, officiating, and choice of sport. Helmet choice does not diminish concussion risk, nor does the use of mouth guards. Education of athletes, coaches, parents, and physicians is very important in improving recognition of potential concussive injury and helping child athletes and their parents understand the risks involved in sport participation.
