Concussion

What Is a Concussion?

A concussion is a minor injury to the brain that briefly disrupts its normal function. A concussion is usually caused by a blow to your head. Even if the blow didn’t knock you out, you may still have suffered a concussion from it.

Most people who take proper care of themselves after a concussion will recover completely. But once you’ve had a concussion, any concussions you suffer after that may be more severe than the first one.

Symptoms

When you suffer a mild concussion, you may:

  • Lose consciousness briefly, or not remember what happened
  • Have a headache
  • Vomit or feel nauseated
  • See stars or flashes of light
  • Feel drowsy or confused

Some symptoms may not show up immediately. If symptoms don’t get better after two weeks, you should tell your doctor.

Causes and Risk Factors

Sports injuries are a common cause of concussion, as are car accidents.

The most obvious way to get a concussion is when something hits your head. But you could also suffer a concussion if your head is jerked suddenly when another part of your body is jolted.

Treatment Options

After a concussion, you will most likely be told to rest, avoid sports activities, and take a pain reliever for your headache.

If your head bleeds or your skull is fractured, you’ll probably need to stay in the hospital.
