A concussion is an injury to the brain caused by a bump, blow, or jolt to the head or body that can change the way your brain normally works. 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.
You cannot see a concussion. Signs and symptoms may appear immediately following the injury or may not be noticed until days or longer after the injury.
If a concussion has occurred, be observant for the following signs. If any of the signs with an asterisk (*) are observed, seek medical attention at the nearest emergency room or call 9-1-1.
