While it has been known that obesity and even being overweight were big risk factors for the incidence of Alzheimer’s Disease (a degenerative disease of the brain causing dementia), a new study of 6500 people, published in the journal Neurology, reveals that a large waistline during middle-age could triple the risk of Alzheimer’s during that person’s old-age.

It has not been conclusively determined as to why a large waist-size is such a good predictor of Alzheimer’s, but theories abound:

Research linking obesity to dementia does not reveal precisely why being overweight can affect your ageing brain, but many specialists believe that associated problems such as high blood pressure, diabetes and high cholesterol levels may contribute. Thickness of fat around the waist is thought to correspond closely with its presence around the major organs of the body.

It could also very well be that the very lifestyle that led to the large waistline in the first case could be the cause the scientists are looking for.
