Scientists Say TV May, In Fact, Rot Your Brain - AOL

Scientists say TV may, in fact, rot your brain focuses on research linking frequent television viewing with measurable changes in brain scans associated with early Alzheimer’s disease. The study, published in Alzheimer’s and Dementia: The Journal of the Alzheimer’s Association, examined data from more than 1,700 adults with an average age of 53 from the long-running Atherosclerosis Risk in Communities Study. Participants reported how often they watched TV during free time and how much time they sat at work; about 20 years later, researchers conducted MRI scans. Those who watched TV “very often” had smaller volumes in brain areas connected to early Alzheimer’s signs and greater white matter hyperintensities tied to cognitive decline and dementia, alongside smaller frontal and occipital lobes.
