My grandma’s Alzheimer

Hi everyone. My 71 years old grandma has been dealing with Alzheimer for a while. Should I hire a nurse or should I take care of her myself? Because I don’t know if family members would help with her disease better or not.
Tuff call... There are many variables...

A nurse can be very expensive..... so can quitting a good job if you're working.

It also depends on how far along she is with her journey. Is she still active or is se bed ridden?
