Sitting for too long may damage brain


The study team noticed thinner medial temporal lobes among individuals who were sitting for long hours compared to those who were having more active job and lifestyle.

Prolonged sitting is often associated with physical health problems like heart disease and metabolic disorders.

Medial temporal lobe thinning can be a precursor to cognitive decline and dementia in middle-aged and older adults. This means that the longer a person sits at a stretch, the worse the effects could be.

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.

To find out more, the researchers recruited 35 people who did not have dementia, aged between 45 and 75 (25 women, 10 men). This was done using the self-reported International Physical Activity Questionnaire modified for older adults (IPAQ-E).

The researchers found that the patients who sat "too much" - anywhere from three to seven hours per day - had a noticeable thinning of the MTL (medial temporal lobe), where new memories are formed.

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. It was found that even high levels of physical activity could not offset the impact of sedentary practices, including lesser gray matter in the lobe. The authors conclude that further studies are needed to understand the relationships between physical inactivity, physical activity, brain transformations and Alzheimer's disease. They would likewise want to check out the function gender, weight and race play in the result on brain health to sitting, inning accordance with the declaration. Also, it does not prove that too much sitting causes thinner brain structures, but instead that more hours spent sitting has a connection with thinner brain regions.

The study was supported by grants from various funders including the National Institutes of Health, the U.S. Department of Energy and the McLoughlin Cognitive Health Gift Fund.
