Alzheimer's Imbalance

African Americans seem to be more susceptible to Alzheimer’s disease than white Americans. But why?

New research published in JAMA Neurology points to a biological clue. Researchers found that while African Americans’ cerebrospinal fluid often contained lower levels of a substance linked to the disease, this did not shield them from Alzheimer’s. The findings suggest differences in the disease across racial groups.

The research doesn’t fully account for risk factors like diabetes and stress, notes an accompanying editorial. Still, writes Lisa L. Barnes of Chicago’s Rush Alzheimer’s Disease Center, it’s a welcome addition given the dearth of Alzheimer’s research on minority groups.
