Researchers from the University of Arizona (USA) found that being overweight can negatively affect cognitive function in the elderly. A key role is played by the inflammatory processes occurring, including, and in the tissues of the brain, according to the website of the University.
According to experts, the higher the body mass index (BMI), the stronger the nervous system occurs inflammation. Therefore, people with obesity may suffer from memory disorders, disorders of attention and reduced intellectual abilities.
the researchers analyzed the results of 12 years of study of health, well-being and socio-economic conditions of the elderly population of the UK. Experts used two separate samples. One consisted of nine thousand people, the other 12.5 thousand. With the aging of each group was monitored for six years. Assessed the BMI, the level of inflammatory processes in the body and cognitive abilities.
it Turned out that the BMI effect on the function of C-reactive protein (plasma protein), reinforcing its role in inflammation. This molecule is a marker of systemic (whole body covering) of pathological processes.
Scientists warn that they discovered the relationship does not mean that is the cause and what the consequence. To confirm the hypothesis about the adverse effect of high BMI, it is necessary experimentally to reduce body weight, and then see how it will change the level of inflammation.
