freezer,

Keep in mind that most medications that act on the brain cells have limited know mechanisms of action. That is why so many doctors use a "try this and report back to me" system of treatment. The hypothetical reasons are just that. As the saying goes. "Your mileage may vary."

Research suggests that there is a component of brain injury that is due to a suicide mission message being sent out. The damaged cells trigger this message in tRNA (transmitting RNA) to create a clean margin of healthy cells by destroying questionable cells. This is a difficult process with diffuse axonal injury as is the most common injury from concussion.

There is no such thing as neuronal or axonal scar tissue. The damaged tissue breaks down and is absorbed. Blood flow will determine how well the damaged tissue remnants will be removed. Also, proper chemical balance is needed to gather all of the waste products of this cellular deterioration. Thus the need for healthy nutrition.
