I had an experience with mom hiring people to take care of her round the clock shortly before she was put into a nursing home. For round the clock care (which what amounts to three CNAs.) it cost $2200 PER WEEK. It can be very costly. Look into assisted living if he/she is able. If not due to medical conditions, then unfortunately it comes down to you (your family) taking care of that person like so many on here are/have done. Or to be placed in a nursing home.
