More Alzheimer’s Risk for Hispanics, Studies Find


... Besides being young Alzheimer’s patients — most Americans who develop it are at least 65, and it becomes more common among people in their 70s or 80s — the three are Hispanic, a group that Alzheimer’s doctors are increasingly concerned about, and not just because it is the country’s largest, fastest-growing minority.

Studies suggest that many Hispanics may have more risk factors for developing dementia than other groups, and a significant number appear to be getting Alzheimer’s earlier. And surveys indicate that Latinos, less likely to see doctors because of financial and language barriers, more often mistake dementia symptoms for normal aging, delaying diagnosis.

“This is the tip of the iceberg of a huge public health challenge,” said Yanira L. Cruz, president of the National Hispanic Council on Aging. “We really need to do more research in this population to really understand why is it that we’re developing these conditions much earlier.”

It is not that Hispanics are more genetically predisposed to Alzheimer’s, say experts, who say the diversity of ethnicities that make up Hispanics or Latinos make a genetic explanation unlikely.

Rather, experts say several factors, many linked to low income or cultural dislocation, may put Hispanics at greater risk for dementia, including higher rates of diabetes, obesity, cardiovascular disease, stroke and possibly hypertension.
