A dangerous relationship between obesity and early brain aging

Scientists at the University of Lapfuro revealed that obesity helped to shrink the brain, causing dementia and other degenerative diseases related to age.

According to the Journal of Neurology, the researchers studied and analyzed the information obtained from the results of 9652 people aged 55.4 years.

After taking into account indicators such as body mass, waist / hip ratio and fat mass, the subjects were subjected to magnetic resonance imaging of the brain. It turned out that five participants are suffering from being overweight, which is in most cases due to an inactive lifestyle.

The researchers found that increases in body mass index and waist-to-hip ratio were related to the decreasing volume of gray matter formed by neurons and glia. The researchers also found that being overweight was associated with a change in the size of certain areas of the brain, such as the responsible nucleus, the cortex, the pale ball, and the retinal nucleus. The researchers have not discovered a mutual relationship between obesity and white matter, consisting of neural axons bundles.

The narrowing of the brain is associated with poor memory and an increased risk of developing dementia and other neurological diseases. However, researchers have not yet determined how obesity could contribute to causing changes in the brain. But they assume that blood vessels are involved in this process. The loss of gray matter complicates the elimination of overweight.
