A new study reveals that the brain’s ability to process visual information may decline more sharply with age than previously believed, challenging long-held assumptions about cognitive aging. Researchers found that older adults experience a noticeable drop in visual perception speed, even when performing simple tasks like identifying shapes or colors. The findings suggest that age-related changes in the brain’s visual cortex could contribute to difficulties in everyday activities, from driving to reading. Experts say the results highlight the need for further investigation into how these declines might be mitigated through lifestyle or medical interventions.
