I am 58 years old and had my first surgery for Hydro over four years age, had my shunt placed three years ago. I had bad dementia for quite awhile. I has gotten much better but the fluid buildup caused severe brain damage.

It can get better, mine has, but it takes patience and a lot of effort. Try diet, exercise, meditation and anything else that works the brain as well as the body. Above all else do not let him sit around feeling sorry for himself.
