Groundbreaking Alzheimer’s detection test approved by FDA

Fox News contributor Dr. Nicole Saphier joins 'America's Newsroom' to discuss a breakthrough blood test to diagnose Alzheimer's and the rise in whooping cough cases seen in Hawaii. 

Many assume that memory loss and cognitive decline are an inevitable part of aging — but new research suggests that doesn’t have to be the case.

A 25-year study from Northwestern University analyzed the brains of "super agers" to determine what traits they share that may contribute to their mental resilience.

"Super agers" are defined as people 80 and older who show "outstanding memory performance" that is on par with those who are three decades younger, according to the researchers.

'MISSING LINK' TO ALZHEIMER'S DISEASE FOUND IN STUDY OF HUMAN BRAIN TISSUE

"‘Super ager’ is not a condition, but rather a term we defined at Northwestern on the basis of a score on a memory test over age 80," lead author Sandra Weintraub, a professor of psychiatry and behavioral sciences and neurology at the Northwestern University Feinberg School of Medicine, told Fox News Digital.

"We were interested in memory aging because memory decline is the most common complaint in older adults. One can be ‘super’ in many ways, and this is just one."

In the study, the researchers analyzed 79 brains that were donated by super agers and identified some key differences compared to those who "age typically."

Some of the brains contained amyloid and tau proteins, which typically accumulate in people with Alzheimer’s disease, while other brains showed no sign of these toxins.

"Some super agers have very few of these proteins, so for some reason they don’t manufacture them," Weintraub noted. "But we found some super agers’ brains contained large numbers of these proteins, despite maintaining their cognitive health until death."

This means there may be different biological pathways to super aging — "one resistance and the other resilience," she said.

"If your relative is forgetful at age 80, it may not be part of aging, but of disease."
