Hi,
Welcome to HealthCareMagic.com I am Dr.J.Mariano Anto Bruno Mascarenhas. I have gone through your query with diligence and would like you to know that I am here to help you.
Dementia can be due to lots of reasons
It can be Alzheimers, or NPH or Chronic SDH
We need to first find the cause and then treat
If it is NPH, VP Shunt may be needed. If it is SDH, Burr Hole may be needed
Hope you found the answer helpful.
