What is a Concussion?
A concussion is a type of mild traumatic brain injury caused by a rapid movement of the brain within the skull. Concussions are often the result of a direct hit to the head but can also result from any blow to the neck, face or body that causes a rotational force on the brain. It may, or more often may not, involve loss of consciousness. During the impact, the brain moves inside the skull. The brain circuits (or cells called neurons) stretch and injure. This impacts the brains ability to function, causing the symptoms of concussion.
Many athletes sustain a concussion and need to sit out a game, a few practices, or even a season. Concussions happen to plenty of non-athletes, too. In fact, millions of people have a concussion each year, and only about half of these are sports related. Concussions can still happen wearing a helmet.
Most people recover completely within two to four weeks. However, symptoms may last for months.
