My mother died from alzheimer's disease 4 years ago, and her sister, my aunt , died from it too, and my mom had 5 aunts on her father's side and all 5 died from alzheimer's. My gene test shows that I had the abnormal allele that causes alzheimer's , apoe episilon 4. One of my children also has the abnormal allele. the rest refuse to be tested, I don't blame them. I wish I didn't know either. But it explains my behavior. Thank you for these videos, it helped me tremendously.
