Alzheimer’s Researchers Test Biomarkers To Advance Diagnosis And Treatment Methods
"For the future, we hope that we might be able to use these biomarkers in order to stop or delay the memory changes from ever happening," Maria Carrillo, chief science officer of the Alzheimer's Association, tells NPR. Meanwhile, other news on aging reports on a potential link between dementia and a prostrate cancer treatment as well as seniors' retirement planning.

New Markers For Alzheimer's Disease Could Aid Diagnosis And Speed Up Drug Development
Alzheimer's disease begins altering the brain long before it affects memory and thinking. So scientists are developing a range of tests to detect these changes in the brain, which include an increase in toxic proteins, inflammation and damage to the connections between brain cells. The tests rely on biomarkers, shorthand for biological markers, that signal steps along the progression of disease. These new tests are already making Alzheimer's diagnosis more accurate, and helping pharmaceutical companies test new drugs. (Hamilton, 7/4)

Dementia Tied To Hormone-Blocking Prostate Cancer Treatment
Alzheimer's disease may be a risk for older prostate cancer patients given hormone-blocking treatment, a large, U.S. government-funded analysis found. Previous evidence has been mixed on whether the treatment might be linked with mental decline. But experts say the new results stand out because they're from a respected national cancer database and the men were tracked for a long time — eight years on average. (Tanner, 7/5)

Poll: 1 In 4 Don't Plan To Retire Despite Realities Of Aging
Nearly one-quarter of Americans say they never plan to retire, according to a poll that suggests a disconnection between individuals' retirement plans and the realities of aging in the workforce. Experts say illness, injury, layoffs and caregiving responsibilities often force older workers to leave their jobs sooner than they'd like. (7/6)
