Obesity also affects the brain

A study by the University of Cambridge says obesity also takes its toll on the brain, aging prematurely when you have extra kilos. According have found, from middle age, the brains of obese people are more like those of lean individuals top ten years. This “premature aging” is seen mainly in l to white matter, composed of the nerves that connect the different areas of the brain and allows information to flow.

A cross – sectional study, which analyzes data from people at a particular time of his life, have examined the impact of obesity on brain structure to investigate whether it is associated with own brain aging changes.  Participants 473 people between 20 and 87 years, recruited by the Cambridge Center for Aging and Neuroscience.  the results are published in the journal  Neurobiology of Aging.

The researchers established two categories based on weight. Thin and overweight people. And they found significant differences in the volume of white matter in the brains of overweight people compared with the thinnest of the same age  Excess kilos is He associated with a general reduction in white matter, compared with people who were on their weight.

They found that an overweight person of 50 years had a volume comparable to other thin white matter of 60 years, which implies an age difference of 10 years to the brain.

These differences were observable only from middle age onwards, suggesting that our brains may be particularly vulnerable during this period of aging.

What intrigues researchers is why people who are overweight have a greater reduction in the amount of white matter. And the interpretation is bidirectional and opens a question: Is obesity which somehow produces these changes or, conversely, obesity results of those changes observed in the brain?

The lead author, Paul Fletcher, Department of Psychiatry, adds: “We are witnessing an aging linked to rising levels of obesity population, so it is essential that we establish how they might interact these two factors, because the consequences health are potentially serious. It will also be important to find out whether these observed changes in the brain may be reversible with weight loss ”

However, despite the clear differences in the volume of white matter between lean and overweight people, the researchers found no relationship between overweight or obesity and cognitive abilities, as measured using a similar standard test to a test intelligence.
