How do I explain to my dad with dementia that he needs to go to a daycare?

Try to convince him to go. Tell him all the benefit of this. Now days many of people who suffering from dementia are going to assisted living Because they no their nurse and doctors are professionals in their fields.

My grandmother who has dementia has been attending a day center for about a year now. She loves it. I don't call it a daycare, we call it The Center. She is picked up and dropped off by a local bus service and she loves the bus ride. It's one of her favourite things to do. Our center here has 2 days a week that are dedicated specifically to people who have dementia/Alzheimer/brain injuries, my Grandma attends on those days. When I first brought up the subject, I basically told her she would be going to spend the day with friends her own age, that she would have lunch there and that she would get to do activities, sing, etc. She really enjoys going. I would suggest calling the daycare you are thinking of having your dad go to and find out about taking him there for a visit, they will usually be okay with having you or your mom, go with him, spend some time there so he can see how things are and how well he will do there. It's definitely an adjustment for him, but people at these places are usually really great and will do all they can to help your dad feel comfortable.
