Dementia risk high for people who sit too much

Dementia risk high for people who sit too much”

The act of being in a seated position is now being linked to changes in the region of the brain responsible for memory, according to researchers at the University of California Los Angeles.

The researchers, including Prabha Siddarth from the University of California, Los Angeles in the United States, asked the participants about their physical activity levels and the average number of hours per day they spent sitting over the previous week. With every hour of sitting each day, there was an observed decrease in brain thickness, according to the study. Thinning in this brain region can be a sign of cognitive decline, the researchers said in a statement.

While researchers have known for some time that sedentary behaviour is bad for physical health, raising the risk of heart disease, diabetes and early death, it is the first study to show it could also influence mental wellbeing.

People who spend more time sitting or engaged in sedentary behavior have thinner brain structures in a region of the brain associated with memory, according to a study newly published in the journal PLOS One.

Then, the researchers scanned the participants' brains.

Unfortunately, they wrote in the study that high levels of physical activity aren't enough to offset the effects of that sedentary behavior. The study said that limiting the number of hours spent sitting could become a recommendation from doctors for their patients at risk of developing Alzheimer's and dementia.

In addition, thefindings are preliminary, and although the studyfocused on hours spent sitting, it did not take into consideration whether participants took breaks during long stretches of sedentary behavior.

The researchers next hope to follow a group of people for a longer duration to determine if sitting causes the thinning and what role gender, race, and weight might play in brain health related to sitting.
