Concussions: Know the symptoms
What is a Concussion?
A concussion is a type of traumatic brain injury (TBI) caused by a bump, blow, or jolt to the head. Concussions can also occur from a fall or a blow to the body that causes the head and brain to move quickly back and forth. A concussion can change the way your brain normally works. Concussions are rarely life threatening, and can range from mild to severe. They can occur even if you do not lose consciousness. Multiple concussions can have cumulative and long lasting life changes.
