My mom is currently 92. She has dementia. Her dementia started approx. 10 years ago after my father died. She’s now in an assisted living facility. My mother’s friend is 93. She’s sharp as a tack, independent and vibrant. I am now 70 years old. Should I expect to inherit my mother’s dementia, or can I do something now so that I can live out my days like my mom’s 93 year old friend. I am with my mom 3 days a week and I see what this disease can do to a person’s quality of life. I really, really don’t want to go there.
