A concussion is a type of traumatic brain injury,
or TBI, caused by a bump, blow, or jolt to the head 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.
Health care professionals may describe a concussion as a “mild”
brain injury because concussions are usually not life-threatening. Even
so, their effects can be serious.
CDC has created two free online courses
– one for health care professionals and another for youth and high
school sports coaches, parents, athletes – that provide important
information on preventing, recognizing, and responding to a concussion.
