I had meningioma res., complications: a sah, hydrocephalus, cerebellar tonsillar herniation, and emergency craniotomy. What's my future hold?

Possible recovery. There is a very good chance of having a very good recovery. It depends on how much neurological injury was sustained and for how long. It seems that if you are able to type and communicate, that you have a very good chance for a near full recovery. Intense rehabilitation will help you improve tremendously. Without knowing your neurological deficits , it is difficult to say for certain.
Depends. Depends on whether you have any residual neurological problems.
