Midlife TV Bingeing Linked to Lasting Brain Changes Decades Later

A long-term USC-led study of about 1,700 adults found that frequent TV watching in midlife is associated with widespread brain changes more than two decades later, including reduced volume in memory-related regions, smaller frontal and occipital lobes, and more white matter damage linked to cognitive decline and dementia, independent of overall sitting or major health risks; occupational sitting showed a different pattern, suggesting not all sitting is equal. Men showed clearer effects, and researchers encourage replacing some TV time with cognitively engaging activities to support brain health.
