According to new research, weight loss surgery which is designed to fight against over-eating and obesity may benefit brain as well as waistline.
Scientists are of the view that there is some evidence that the surgery may lessen the risk of Alzheimer's disease.
In a Bariatric surgery, either the size of the stomach is reduced or the distance which food travels through the digestive tract is shortened.
The impact of bariatric surgery on 17 obese women was studied. It was found that there were distinct improvements in mental functions which are connected to organization, planning and strategy.
"When we studied obese women prior to bariatric surgery, we found some areas of their brains metabolized (processed to produce energy) sugars at a higher rate than normal weight women. In particular, obesity led to altered activity in a part of the brain linked to the development of Alzheimer's disease," added Professor Cintia Cercato from University of Sao Paulo, Brazil.
