Black and Latino patients who are diagnosed with Alzheimer’s tend to live longer after their diagnosis than people of other races and ethnicities, suggests new research. Researchers at the University of California, San Francisco examined information on more than 31,000 people above the age of 65 and found that black Alzheimer’s patients lived 15 percent longer than white people and people of Asian and American Indian descent. Latino patients were found to live 40 percent longer. However, the researchers say that more work needs to be done to uncover the reasons behind these survival rate disparities.
