Watching too much TV in midlife may shrink the brain
A study published in Alzheimer's and Dementia found that adults who watched television 'very often' during midlife had smaller brain volumes in regions associated with memory and cognitive decline. Researchers analyzed data from approximately 1,700 adults and discovered that heavy TV viewing correlated with reduced frontal and occipital lobe volume, as well as increased white matter damage, which are linked to aging and dementia risk. The findings suggest that the type of sedentary activity, such as watching TV, may significantly impact brain health beyond mere inactivity.
