>> I wonder if Alzheimer, just like heart disease and diabetes is mostly a western diet-related disease. Nope. One of the professors I worked with in grad school did some groundbreaking Alzheimer research on Germans from Russia: We have studied 28 kindreds with familial Alzheimer’s disease (FAD) that are all descended from the ethnic group of Germans from Russia. Eighteen families were of Volga German ancestry, originating from the same two villages and containing 132 demented individuals. These families represent a model of genetic heterogeneity when compared with other reported FAD kindreds. Because of their common, isolated ethnic background, the Volga German families are likely to represent the founder effect and a single, as yet unidentified, autosomal dominant mutation. The Black Sea German kindreds may represent additional heterogeneity. https://link.springer.com/chapter/10.1007/978-3-642-46776-9_13 https://link.springer.com/chapter/10.1007/978-3-642-46776-9_...
