African-Americans may be twice as likely as Caucasian Americans to develop Alzheimer’s disease, but nobody knows why because studies investigating the underlying causes of illness have historically drawn from a nearly all-white pool of research participants. Consequently, little is known about how the neurodegenerative disease arises and progresses in people of non-Caucasian backgrounds.
