Normal Pressure Hydrocephalus

Well, we are having my mom tested by a neurologist. We are praying that she is diagnosed with NPH. She is probably not healthy enough for a brain shunt, but I understand there is other treatment. I have read about people who are diagnosed with Alzheimer's or other types of dementia, who actually had NPH, so when they were treated for the correct illness, their health improved. Does anyone have any experience with NPH, dementia, or Alzheimer's?
