The Relationship of Alzheimer’s Disease, Stroke and Ancestry in the Puerto Rican Alzheimer Disease Population.

The Puerto Rico Alzheimer and Related Dementias Initiatives (PRADI) patient cohort was developed to investigate AD and the associated genetics factors in the Puerto Rican population. PRADI recruitment was a snowball sampling, with both island‐wide geographic distribution, and extensions of the PR communities in the continental US. A prior analysis suggested that stroke is a contributing factor to AD in the PR population. In this study we further evaluated the association between stroke and AD, while considering also age, gender, and ancestry.
