The life of Jose and Elaine Belardo was turned upside down last year when he was diagnosed with early Alzheimer's disease.

José Belardo of Lansing, Kansas, spent most of his career in the United States Public Health Service. He has worked on disaster front lines in places like Haiti, Colombia, Nicaragua and the Dominican Republic. At home with his three children and his wife, Elaine, he had always been infallibly reliable, so when he forgot their wedding anniversary two years in a row, they began to worry

"We have recognized that something was wrong. Says Elaine

but the symptoms have increased. Last year, while Jose was 50 years old, he was the subject of an assessment at the Walter Reed Medical Center that included a battery of cognitive tests and a PET scan of his brain. The analysis detects beta-amyloid plaques clusters of protein fragments that accumulate particularly in the brains of people with Alzheimer's disease (although some older people in good health also wear these plates).

Jose says his diagnosis of early onset of Alzheimer's disease came as an embarrassing shock. Still, he and his wife believe that it's better to have a diagnosis than no. Jose says that he is determined to try not to let the shock of the diagnosis distract him from living his life to the full. "

Rear-Admiral Jose Belardo traveled around the world and worked with national leaders in the US Public Health Service.

"I have responsibilities, man, I can not leave," Jose said. I have kids, I have upcoming degrees, I have all that stuff to come, I will not let Alzheimer's disease s.Mr. away from me.

The prospect of having Alzheimer's disease can be so scary, and the current treatment options so few, that many people dismiss memory problems or other symptoms rather than to study them, say Alzheimer's specialists; it is estimated that up to half of all cases are undiagnosed.

But that could soon change. Researchers are making progress in measuring biomarkers of beta-amyloid and other Alzheimer's in the blood that could possibly identify the disease reliably, inexpensively, and noninvasively years before cognitive symptoms develop

. t are widely available, and most other biomarker tests are still experimental. But John Morris, a researcher on Alzheimer's disease and a professor of neurology at Washington University in St. Louis, thinks that these physiological measures will mark a new chapter in the management of Alzheimer's disease.
