Worried You May Be Developing Alzheimer's? Check Your Eyes


People worried they might be developing early signs of Alzheimer’s may be able to ask their eye doctors to have a quick peek during a regular exam, experts reported Sunday. Or they may be able to take a simple smell test.

Four studies being presented at the Alzheimer’s Association International Conference in Copenhagen, Denmark, strengthen earlier evidence that the earliest signs of Alzheimer’s disease might show up in the eyes and nose.

That could mean earlier treatment, and could give people a chance to plan, said Maria Carrillo, vice president of medical and scientific relations at the Alzheimer’s Association.

“There are treatments for symptoms that work best early in the disease process. As time goes on less effective,” Carrillo told NBC News. “We want to get people on those treatments as soon as possible, while they are still useful.”
