A s brain shrinkage is linked to dementia, the study adds weight to the suspicion that piling onthe pounds may up a person's risk of the brain condition, according to them Moreover, as increased body fat ups the chances of having clogged arteries, that can reduce blood and oxygen flow to brain cells, the resulting reduction in metabolism causes brain cell death and the shrinking seen, the researchers said.
"The brains of overweight people looked 8 years older than the brains of those who were lean, and 16 ears older in obese people, " lead researcher, Mr. Paul Thompson, the Calilfornia University was quoted as saying by the new Scientist. The team has shown that the exercise, which improves blood flow, protects the shrunk brain regions.
