Why: Mischa hit his head, gushed blood, and decided to wash his hair. Jamie thinks he had a concussion. All I know about concussions is that you're not supposed to go to sleep.
Answer: Concussions temporarily interfere with the way your brain works. They can range from minor to major, and some people get them (usually from a blow to the head) without even realizing it. Early symptoms can include:
- Amnesia (especially of the impact that caused the concussion)
- Headache and dizziness
- Ringing in the ears, nausea, vomiting, fatigue, and/or slurred speech
- Sensitivity to light and noise
- Loss of consciousness
Anyone who has had one is at higher risk of having one in the future, and people who experience multiple concussions can experience cumulative neurological damage. A link between multiple concussions and the eventual development of Alzheimer's disease also has been suggested.

The More You Know: It's all bullhonky. Medical Myths:
Myth: Keep someone awake who has had a recent concussion.
Fact: A person who has had a concussion may sleep through the night.
You do not need to keep awake a person with a recent concussion. This was recommended for years to observe a person for any changes after a concussion. People worried that the person may go into a coma and never wake up. This is no longer believed to be true. You can allow someone to sleep after a concussion. This should cut down on sleep deprivation for all involved.
People with concussion should be seen by a doctor if they were unconscious for more than 5 minutes or amnesia persists or if they do not appear to behave normally.
At home, rest is the best way to recover from a concussion. Get plenty of sleep at night and take it easy during the day. To prevent a second brain injury, avoid alcohol, illegal drugs, and any activities that could lead to another head injury for a few days or even a few weeks. Your doctor may also tell you not to drive or swim for a while.
