The literature that I have read indicates that even mild TBI causes lasting loss of neurons in the brain.

My concussion was just over a week ago and resulted in unilateral pain, nausea and mild brain fog. Not as bad as many others, but still very troubling.

I believe symptoms are both functional and structural. Unfortunately, structural damage to the brain seems to be permanent. If someone could show any evidence to the contrary, it would be very helpful to us.

Why is it that some people recover so well and others don't? Is it down to genetics or are there environmental factors that we can take advantage of to help recovery?
