According to the Brain Injury Association of America, more than 3.5 million children and adults sustain an acquired brain injury (ABI) each year. There are many causes of ABI some of which are: infectious disease, stroke, oxygen deprivation, substance abuse, seizure disorder, toxic exposure, or trauma. In a sports setting, a concussion is a type of MILD traumatic brain injury in which the brain receives trauma from a sudden change in momentum or movement. Signs of a concussion can include headache, feeling dazed or “in a fog”, irritability, dizziness or difficulty orienting to ones surroundings, nausea, or vomiting. It is important to remember that not ALL concussions require a loss of consciousness. Some athletes can look “normal” after a sports related trauma even though they had a concussive event. it is important for coaches, trainers, parents and doctors to know what the signs and symptoms of concussions and treat them appropriately.
