Research on Superagers Reveals Insights into Cognitive Longevity
Recent studies conducted by neuroscientists at the Northwestern University Mesulam Institute for Cognitive Neurology & Alzheimer’s Disease have uncovered significant findings about 'superagers'—individuals in their 80s with memory capacities comparable to those of much younger adults. The research, which spanned 25 years, focused on the hippocampal tissue of 38 individuals across various cognitive health groups, including superagers. The findings revealed that superagers possess about twice the number of immature neurons capable of maturing into adult brain cells, a trait not observed in individuals with Alzheimer’s disease. Additionally, superagers' brains exhibit less cortical thinning and a higher density of specialized neurons known as Von Economo cells, which are crucial for rapid response and emotional regulation.
