A team of researchers led by Li-San Wang, professor of pathology and laboratory medicine in the Perelman School of Medicine at the University of Pennsylvania, has been awarded a two-year pilot grant expected to total $4.8 million from the National Institute on Aging (NIA), part of the National Institutes of Health, for studies of the genetics of Alzheimer’s disease in people of Asian heritage.
Alzheimer’s disease (AD), the most common cause of dementia among seniors, affects about 6.5 million people in the United States and Canada combined. Its prevalence is expected to increase significantly in the coming decades as these countries’ populations age. The cause or causes of AD are still unclear, and success testing therapeutic targets to slow or stop the disease process has been elusive in the last two decades despite many clinical trials. Scientists continue to seek clues to the disease’s origin in large genetic studies as well as studies of lifestyle and other factors. But while susceptibility to diseases may differ by ethnicity, and indeed small genetic studies suggest that Asians may have a distinct set of genetic risk factors for Alzheimer’s, studies of this disease (and many other complex diseases) so far have recruited mostly populations of European ancestry.
