United StatesA study published in Alzheimer’s Dementia: The Journal of the Alzheimer’s Association found that heavy television watching in midlife was linked to brain changes associated with Alzheimer’s disease. The research followed over 1,700 individuals for nearly 24 years, tracking their TV habits and later analyzing their brain structures via MRI scans. Men who spent significant time watching TV exhibited reduced brain volume in regions vulnerable to Alzheimer’s, increased white matter damage, and smaller frontal and occipital lobes. These associations were not observed in women. The study noted that prolonged sitting at work did not yield similar brain changes, indicating that not all sedentary behaviors impact the brain similarly. Lead researcher Natan Feter suggested that differences in viewing habits, such as men watching longer, uninterrupted sessions, might explain the gender disparity. Experts advised incorporating mental engagement and physical activity while watching TV to mitigate potential risks.
