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 adults, certain neural pathways linked to memory and decision-making weaken faster than expected, particularly after middle age. The findings suggest lifestyle and environmental factors could play a more critical role in slowing this decline than genetic predisposition alone. Experts warn the results may reshape approaches to brain health in later years, emphasizing early intervention strategies.
