Black Americans have been underrepresented in most genomic studies of neurological disorders. As a result, scientists don't know much about whether African ancestry affects a person's risk for these disorders or their response to a particular treatment.

The team found that genes associated with African ancestry appear to affect certain brain cells in ways that could increase the risk of Alzheimer's disease and stroke.
