A new study reveals that the brain’s ability to process and retain information may decline more sharply after age 70 than previously believed, challenging long-held assumptions about cognitive aging. Researchers found that while memory and learning skills weaken gradually in earlier decades, the rate of deterioration accelerates significantly in later life, particularly in tasks requiring speed and working memory. The findings suggest that interventions targeting middle-aged adults could play a critical role in mitigating future cognitive decline. Experts emphasize the need for further investigation into the underlying biological mechanisms driving this accelerated change.
