How can we convince Pop to seek help in dealing with Mom and the dementia?

The only thing i know for you to do, is what I did.I had been trying to get my exs, daugthers to get help for their dad ,but all they would say was that didn't won't to hurt his feeling. So when I got so tired of hearing this.I went to the Dr. with hem and ask the Dr. what to do.At that point the Dr. had seen a change in him.And started him on aircept.Some times we have to take the matter in our owen hands, and see what happeness. Good luck.
