Obese people are more at risk of Alzheimer’s

In a new study scientists have found that people who are obese have smaller brain & they are more at risk of Alzheimer’s. They found that brain in the obese people had an average of 8 % less tissue & had aged prematurely by sixteen years. On the other hand people who are overweight had an average of 4 % less tissue & appeared eight years older.

They compared the brain scan of 94 people in their 70s who were obese & overweight. They found that the obese had lost tissue in the frontal & temporal lobes areas critical for planning & memory. Declines were also seen in areas used for attention & executive functions, long term memory & movement

A neurologist Professor Paul Thompson said, “That's a big loss of tissue and it depletes your cognitive reserves, putting you at much greater risk of Alzheimer's and other diseases that attack the brain. But you can greatly reduce your risk for Alzheimer's if you can eat healthily and keep your weight under control.”

There are more than 300 million obese people around the world, with a billion more overweight. They are at increased risk of heart disease, diabetes and high blood pressure says The World Health Organization. Along with increased risk for health problems such as type 2 diabetes and heart disease, obesity is bad for your brain
