Well...in a case like this I guess the only thing we can do is keep the faith. That is the number one thing we can do. As I'm sure you know, an injury to the brain can sometimes take years to recover and in some cases there will never be full recovery. A friend of mine who I have known for 3 years now suffered a real serious brain injury 10 years ago where she forgot everything and she was very irritable too for a long time. Now she is doing quite well. There is hope! It just takes patience and faith. Hang in there.
