Baseline concussion testing is a pre-season exam that assesses an athlete’s balance and brain function. This includes learning and memory skills, the ability to pay attention or concentrate, how quickly he or she thinks and solve problems, as well as for the presence of any concussion symptoms. Many of us understand concussion is a traumatic brain injury (TBI) that may result in a bad headache with altered levels of alertness, or even unconsciousness. But, did you know that a concussion temporarily interferes with the way your brain actually works? Concussion can affect memory, judgment, reflexes, speech, balance, coordination and even sleep patterns.
