Washington: Alzheimer’s disease (AD) hits hardest among the “younger elderly” – people in their 60s and 70s – who show faster rates of brain tissue loss and cognitive decline as compared to patients 80 years and older, a new study has revealed.The greatest risk factor for Alzheimer`s disease (AD) is advancing age. By age 85, the likelihood of developing the dreaded neurological disorder is roughly 50 percent.The findings by researchers at the University of California, San Diego School of Medicine have profound implications for both diagnosing AD – which currently afflicts an estimated 5.6 million Americans, a number projected to triple by 2050 – and efforts to find new treatments.There is no cure for AD and existing therapies do not slow or stop disease progression.“One of the key features for the clinical determination of AD is its relentless progressive course,” Dominic Holland, the study’s first author, said.“Patients typically show marked deterioration year after year. If older patients are not showing the same deterioration from one year to the next, doctors may be hesitant to diagnose AD, and thus these patients may not receive appropriate care, which can be very important for their quality of life,” he said.
