Brain changes, weight loss, and even infection history could help pinpoint who might be at risk
Alzheimer’s disease and other related dementias are characterized by progressive cognitive decline, and with an aging population, the number of older Americans with dementia is expected to rise dramatically in coming years. But dementia is not an inevitable part of aging.
New studies funded by the National Institute on Aging (NIA) identify early warning signs of cognitive decline and key factors that contribute to dementia risk. Early diagnosis allows access to treatments that can delay the onset or slow the development of dementia, improving the health and well-being of dementia patients and their caregivers and reducing health care costs.
