Or also pressure hydrocephalus, diabetic, obese age 65 life expectancy. Normal pressure?

What kind. I am unfamiliar with also pressure hydrocephalus- did you spell the type correctly? For most causes of hydrocephalus, the type determines the treatment and forecast. The diabetes-how long, level of control, other vascular issues, and meds also figure in to the forecast you are seeking. Too complicated for this format.
