Are there any cures for concussion besides rest?

There is no doubt that rest helps a brain recover from a concussion. There is research going on to determine how much rest is needed, but each concussion is treated individually. Typically, mental and physical rest is advocated. There is also research going on looking at medications that may be useful to prevent the progression of concussion, based on the physiology of what happens when the brain is initially concussed, and to help the brain "heal" more quickly.
