<2> Superagers’ ‘Secret Ingredient’ May Be the Growth of New Brain Cells
<3> Exceptional Memory in Aging: A New Discovery
<4> A recent study conducted by researchers at the University of Illinois Chicago has shed light on the secret behind superagers’ exceptional memory. According to the study, superagers have roughly twice as many immature neurons as their peers who age more typically. This discovery has significant implications for our understanding of aging and cognitive decline.
<5> The study analyzed postmortem hippocampal tissue samples from five groups: healthy young adults, healthy agers, superagers, individuals with preclinical Alzheimer’s pathology, and individuals with an Alzheimer’s diagnosis. The researchers found that superagers had twice the neurogenesis of the other healthy older adults, with a marked increase in immature neurons.
<6> “Something in their brains enables them to maintain a superior memory,” says neuroscientist Orly Lazarov of the University of Illinois Chicago. “I believe hippocampal neurogenesis is the secret ingredient, and the data support that.”
<7> The study also found that individuals with preclinical Alzheimer’s pathology and Alzheimer’s diagnoses showed a marked reduction in neurogenesis compared to a normal baseline. This suggests that the system supporting new
