A new study reveals that the brain’s ability to process and retain information may decline more sharply with age than previously understood, challenging long-held assumptions about cognitive aging. Researchers found that even in healthy individuals, neural pathways responsible for memory and decision-making weaken faster than expected, particularly in middle age. The findings suggest that lifestyle interventions could play a critical role in mitigating these declines, though the exact mechanisms remain under investigation. Experts caution that further work is needed to distinguish between normal aging and early signs of neurodegenerative conditions.
