My mama had vascular dementia. She was also lactose intolerant, so ate very little cheese. Fortunately, I’m not lactose intolerant. I eat whole fat cheese on a nearly daily basis.
My mom has it and is a home at 85.
Her issue was she had/has high BP and literally never took her BP meds.
I keep my BP at 110/70, which is fine except when I stand up after a full meal, lol.
