I just read the TBI guide (*link attempt edited*).

The author says it is impossible to get back to 100% but we just have to cope with what has become of us (whether it is 99% or 80%).

The prospect of permanent damage is very disturbing to me.

Are there any cases where a full recovery has been measured and quantified (e.g. IQ scores before concussion and after recovery)?

What are your thoughts?
