Long-term low physical activity and/or high television viewing may raise Alzheimer’s risk

The Washington Post reported that too much television “might damage your brain and also raise the risk of developing Alzheimer’s disease — and that the effects could show up much sooner than previously believed,” according to research presented at the Alzheimer’s Association International Conference.

HealthDay reports that after tracking “more than 3,200 white and black Americans, aged 18 to 30,” focusing on “levels of physical activity and television viewing over 25 years,” researchers found that “people with long-term low physical activity, as well as people with long-term high television viewing, scored much worse on the tests compared to those who were more active and watched less television.”

Individuals “with both long-term low physical activity and high television viewing were nearly two times more likely to have poor mental function in mid-life, the study found.”

These findings were presented at a medical conference. They should be considered preliminary as they have not yet undergone the “peer review” process, in which outside experts scrutinize the data prior to publication in a medical journal.
