My 86 year old mother was diagnosed with (not specific type) dementia last year. My paternal grandmother had dementia. My maternal grandfather did not have dementia. My father, paternal grandfather, and maternal grandmother died before age 63 without exhibiting dementia symptoms. My primary doctor confirmed that dementia is usually genetic, passed down through the family. My question is what are my chances of have this disease and what can I do now to prolong onset or minimalized effects as much as possible if I do have dementia in the future? I am a 64 year old female and still working as a high school biology teacher. I will retire in two years.
