Researchers at the University of California, Los Angeles, generated 3D maps of over 200 healthy elderly people's brains & found a pattern of diminished brain volume in people with a specific DNA sequence within the fat mass & obesity-associated (FTO) gene.
"We've known for some time that there's a link between obesity in mid life & the development of Alzheimer's disease. However this study suggests that healthy people who carry a specific DNA sequence associated with obesity could be at a greater risk of developing dementia. A reduction in people's brain tissue was observed but this wasn't linked to other obesity-related factors such as cholesterol levels, diabetes or high blood pressure.-Dr. Susanne Sorensen, Head of Research Alzheimer's Society.
This is a relatively small study but the findings support the need for more research. One million people will develop dementia in the next 10 years but dementia research is desperately under-funded, however with the right investment, it can be defeated."
