Alzheimer’s: Watching television may increase the risk of dementia in older adults, research finds


A new study monitored “cognitively passive behaviors” in people over the age of 60

THE WASHINGTON POST – How adults spend their sedentary time – what they do when seated, for example – makes a difference in their chances of developing dementia, according to research published in the journal Proceedings of the National Academy of Sciences.

The study points out that those whose sedentary time is mainly spent watching the TV have a 24% higher risk of developing dementia, while computer users have a 15% reduced risk.

The researchers explained that watching television is a passive cognitive activity, during which little reflection is needed. At the same time, the computer is cognitively active, which means it is, as is the readingmore intellectually stimulating.

For both groups of study participants, the likelihood of developing dementia associated with the habit of sitting persisted, regardless of the amount of physical activity performed at other times of the day. Previous research had already highlighted the benefits of physical exercise in reducing the risk of cognitive loss and dementia.

Dementia, which is not considered a normal part of aging, is an umbrella term to refer to a range of symptoms – memory loss, confusion, speech problems, logical thinking, and behavioral changes – that worsen over time and affect activities. of an individual and life.

or Alzheimer’s it is the most common type of dementia. Today, the disease affects around 1.2 million Brazilians, according to the Ministry of Health, and more than 50 million people worldwide.

The survey was conducted on more than 146,000 adults over the age of 60 who had no signs of dementia when they were interviewed. After more than 12 years of follow-up, around 3,500 volunteers showed signs of the disease.

Therefore, the study concludes that “reducing cognitively passive sedentary behaviors, such as watching TV, and increasing cognitively active ones, such as computer use, even in minimal quantities, can have a major impact on individuals’ risk of dementia, regardless from their involvement in physical activities “.
