ESPWatching television very often in midlife may be linked to troubling brain changes decades later. In a study of about 1,700 adults, frequent TV viewers later showed smaller brain regions involved in memory, decision-making, and visual processing, along with more signs of damage in the brain’s white matter. Surprisingly, sitting itself did not appear to be the main issue, since people who spent long hours seated at mentally engaging jobs often showed healthier brain patterns.
"Turn off that TV, it'll rot your brain!" has been repeated in households for generations. The word "rot" is clearly an exaggeration, but new research suggests that heavy television viewing may still have meaningful consequences for brain health.
A recent study published in Alzheimer's and Dementia: Journal of the Alzheimer's Association found that adults who said they watched television "very often" during midlife later showed smaller volumes in brain regions tied to memory. They also had reduced frontal and occipital lobe volume and more damage in the brain's white matter, changes that have been associated with aging, stroke risk, cognitive decline and dementia.
