MOSCOW, January 29 - RIA Novosti. Excess weight puts additional stress on the brain, impairs cognitive function and can worsen Alzheimer's disease.
Scientists at the University of Sheffield conducted a multimodal neuroimaging study, during which they studied data from 47 patients with a clinical diagnosis of dementia in Alzheimer's disease, 68 patients with mild cognitive impairment and 57 cognitively healthy people.
Experts measured differences in local brain tissue concentrations to assess the relationship between gray matter volume, white matter integrity, cerebral blood flow, and obesity.
The results showed that in patients with mild dementia, there is a positive association between obesity and the volume of gray matter around the right temporo-parietal junction.
Scientists have concluded that being overweight puts an excess burden on brain health and contributes to the vulnerability of nerve tissue. However, maintaining good physical condition in mild dementia caused by Alzheimer's disease helps preserve brain structure.
