For both groups of study participants, their odds of developing dementia linked to their sitting persisted,
no matter how physically active they were at other times of the day.
Previous studies have pointed to physical exercise as beneficial to reducing risk for cognitive decline and dementia.
Dementia, which is not considered a normal part of aging, is an umbrella term used to describe a set of symptoms —
memory loss, confusion, problems with language and reasoning, and behavioral changes — that progress over time
and affect a person’s daily life and activities. Alzheimer’s disease is the most common type of dementia.
Today, about 6 million people in the United States have Alzheimer’s and related dementias — most older than 65
and more women than men — and the number is expected to increase to 14 million by 2060, according to the
Centers for Disease Control and Prevention.
As the researchers concluded, “reducing cognitively passive [sedentary behaviors] like TV watching
and increasing cognitively active [ones] like computer use, by even a small amount, may have an important
impact on dementia risk in individuals, regardless of their engagement in physical activity.”
