Scientists find beer belly link to Alzheimer's

PEOPLE with fat stomachs could be at a greater risk of developing dementia, warn scientists.

The Alzheimer's Society says the results of the study, of more than 700 middle-aged people, indicates more work needs to be carried out on the link between obesity and dementia.

The research, carried out by the University School of Medicine in Boston, Massachusetts, shows that the higher the levels of visceral fat – the fatty tissue surrounding the organs – the smaller the total brain volume.

Dementia is strongly associated with low brain volume, an Alzheimer's Society spokeswoman said.

Dr Susanne Sorensen, head of research at the society, said: "We have all heard how a beer belly can be bad for our heart, but this study suggests carrying excess abdominal weight could also increase your risk of getting dementia.

"This is not really surprising as a large stomach is associated with high blood pressure, cholesterol and diabetes – all major risk factors for dementia.

"While this large and robust study builds on the growing literature looking at links between obesity and dementia, more work is needed."
