Why are we told not to sleep after a concussion?

Steven Wasmer  asked the Naked Scientists:
   
Hello naked scientists!

A recent incident at a rugby game got me thinking.

Why is it not safe to sleep after a concussion. It seems everyone at the game agreed that one shouldn't sleep but nobody could really say why or even for how long sleep should be prevented. Some people even thought sleep would be OK but only in one hour shifts. What's the the official course of action and why?

Great show!

Steve

What do you think?

Sometimes after a concussion the person will seem fine, but if there is also a tear in the outer meninges around the brain and a broken blood vessel, blood  can accumulate there. Since it can't expand outward because of the skull, it will compress the brain, causing unconsciousness and possibly death. This is called a subdural hematoma. So the reason they don't want you to go to sleep, is that someone observing you might not be able to tell that you were in trouble.
