All the posts are very helpful, thank you. I think both of my parents now have dementia, although they don't have an official diagnosis (as far as I know). They manifest all the symptoms and patterns described above - repeating questions, overestimating their abilities, having paranoid thoughts, being depressed. The biggest problem is that they refuse help, even if I don't offer anything major - just to run errands, for example. My Dad especially, he gets very angry at times, whenever help is offered, or any suggestions to change anything are made. I live in another state. I am planning on moving to be close to them, but I am at my wits' end as to how to handle this situation in the future. I don't know what the best living situation would be, and living in their house would be disastrous for my well-being, I am pretty sure of that. Besides, they only have one small extra room. I know that aging people have increased desire to control, and with my parents it has become close to OCD. If anyone can advise on who or what entity would be of help here, I'd greatly appreciate that. I should mention that my mom flatly refuses to consider assisted living facility, even at the independent living level, and I myself don't feel good about placing either one of them in someone else's care - at least not at this point.
