Age-related smelling loss significantly worse in African-Americans


The ability to distinguish between odors declines steadily with age, but a new study shows that African-Americans have a much greater decrease in their sense of smell than Caucasians. This can have serious consequences. Olfactory loss often leads to impaired nutrition. It also may be an early warning sign of neurodegenerative diseases, such as Alzheimer's or Parkinson's, and can predict death.
