 But insofar as type 2 diabetes is a risk factor for Alzheimer's disease, I think it can be expected that this might reduce risk. Right. So for you personally, what you saw in your mom, was it behavioral or did she inherit that? No. So the heritability of these conditions are very low. So Parkinson's disease is minimally heritable. About 2% to 3% of cases are considered to be inherited. And with Alzheimer's disease, similar, only about 2% to 3% of cases. Analyzing that your mom got it, how do you think she got it?
