It's especially great to see as someone with several grandparents and grand-uncles who suffer from the disease. I know it's not completely hereditary, but between those 4 and the 2 cases of Parkinsons old age for myself and my family is not looking good. One thing that's confusing and distressing to me is the amount of self-inflicted difficulty that the diseases seem to cause people to suffer from. If asking "What have you had to drink? Have you taken your meds? What have you eaten?" can cause them to feel so much better, what is it about aging, about the treatments, and about the disease that makes people neglect taking care of themselves? It's usually hard to convince someone who is thirsty to not drink. Depending on who you talk to, the level of hydration that results from drinking when you're thirsty may not result in being completely well-hydrated, but that's not difficult or painful to do either - keeping a water bottle with me seems to get close enough. But it's not like you can blame the person with the disease. What's the systematic problem that causes so many elderly to suffer from dehydration?
