My grandfather had dementia and my grandmother had Alzheimer’s. With dementia, from what I understand from my cousin who works with people who have dementia, it happens to everyone eventually. You have sundowning,* where later in the day you can’t remember stuff as well as your memory and your cognition kind of deteriorates. So with my grandfather, it just seemed like a natural progression. It was really noticeable not last summer but the summer before last. I went to live with them after he had a stroke, and I saw him at night a lot and you could see, seeing him day in and day out, over the course the day, the deterioration of the mind.
