We’ve long known that African-Americans have a higher risk of Alzheimer’s disease than white Americans. But we’ve never had a clear explanation -- until now. A study being presented this week at the Alzheimer’s Association International Conference in Boston says socioeconomic factors are to blame for that disparity.
The Alzheimer’s Association’s 2013 Alzheimer’s Disease Facts and Figures reports older African-Americans are twice as likely to suffer from aging-related dementia or Alzheimer’s as white counterparts. (Hispanics are 1.5 times as likely to have Alzheimer’s.)
