Father with dementia won't eat?

Olivia
I'm looking for a healthcare provider that is well versed in dementia or someone who has had to care for someone with dementia. I need some advice. My father has early on set dementia in his mid 50's. My mother's goal is to keep him at home for as long as possible, but we know eventually he can't stay here. In the day, he goes to an adult daycare that he seems to like. However, when he is at home it is becoming a challenge to get him to eat!!! When we set a plate down in front of him he'll jump and just start wandering the house!!! He won't even touch the plate even though we keep telling him there's food. Then, when he does decide to eat the plate is cold by then and we go to heat it up. Then, he starts walking around AGAIN. 😞😞😞 it's incredibly frustrating. Or, he'll take about 2 bites out of the plate and he's done. He is on about 3 medications I believe. Is there anything we can do about the eating situation? We don't know what else there is to do. Thank you.
