In some ways, I'd rather not know or think about it. I'm sure many people feel the same way. At the same time, I want to know what's going to happen next. In the past year, my father has lost his drivers license, has had a major increase in 'Off' periods, become more off balance, and has started having cognitive problems. He now has dementia, needs to use a walker a lot of time and is taking medication for anxiety and to help his thinking process. He takes his parkinson's medication every 2 hours from 4am - 9pm. What is going to happen next??? Does anyone know?
