As a parent of a young child, very active in a wide variety of sports, as well as a member of the University of California Sports Medicine Team, Dr Johnson has become well informed regarding concussions by attending many seminars, symposiums and national summits.
He provides this section prominately on this site as a public service to help promote Concussion Awareness through out the community.
A concussion is a traumatic brain injury (TBI) that may result in a bad headache, altered levels of alertness, or unconsciousness.
It temporarily interferes with the way your brain works, and it can affect memory, judgment, reflexes, speech, balance, coordination, and sleep patterns
A concussion may result when the head hits an object or a moving object strikes the head. A concussion can result from a fall, sports activities, and car accidents. Significant movement of the brain (called jarring) in any direction can cause you to lose alertness (become unconscious). How long you remain unconscious may be a sign of the severity of the concussion.
However, concussions don't always involve a loss of consciousness. Most people who have a concussion never black out. You can have a concussion and not realize it.
