A concussion is a type of traumatic brain injury caused by a bump, blow or jolt to the head or by a hit to the body that causes the head and brain to move rapidly back and forth, according to Centers for Disease Control and Prevention – Injury Centre.

A person who experiences a concussion does not necessarily lose consciousness. Signs and symptoms of a concussion can be subtle and may not show up immediately. Effects from a concussion can be temporary or can last days, weeks or even longer.
