LONDON (Reuters) – Some parts of the human brain can contract heavy losses, British researchers said on Wednesday.
"This effect is found mostly in people who accumulate fat in the middle of the body," said the researchers in their study published Thursday in the journal Neurology, specializing in neuroscientists.
At the same time, however, it is not yet clear that weight gain is causing these changes in the brain, or that brain changes contribute to weight gain.
The researchers have not tried to study the consequences of brain changes that have been found in overweight people.
There is no doubt among scientists that weight gain can be the cause of many diseases, including diabetes, joint pain, circulatory system diseases and breathing difficulties.
It is not yet clear if this increase also represents a risk for the brain and what is the magnitude of the risk. Previous studies have shown signs of such a risk.
Researchers under the supervision of Mark Hammer, a sports medicine specialist at Loughborough University, have studied the effects of being overweight on what is called gray matter in the brain.
For this, the researchers evaluated 9652 people, whose average age was 55, and obtained the body mbad index (BMI) of these people, which measures the body weight according to the size , as well as the waist / hips ratio.
19% of these people were considered obese, with a group index of 30 or more, with a natural mbad index of 18.5 to 25.
The researchers then determined the brain size of these people using magnetic resonance imaging (MRI) to determine the size of the gray and white substance.
The researchers found in the study that gray matter size in people with a mbad index, as well as in those with a waist / hip ratio smaller than the size of those with a natural index of hip size. .
