To investigate, researchers from Boston University School of Medicine recruited participants from the Framingham Heart Study Offspring Cohort. Study participants included over 700 people who had a mean age of 60 years.
Researchers examined the association between Body Mass Index (BMI), waist circumference, waist to hip ratio, CT-based measures of abdominal fat, and various brain measurements, including MRI measures of total brain volume, temporal horn volume, white matter hyperintensity volume and brain infarcts in the middle-aged participants.
They found that people with the highest levels of visceral fat - the fatty tissue surrounding the organs - also had the smallest total brain volume, a risk factor for dementia. Not surprisingly excess abdominal fat is often associated with high blood pressure and cholesterol, as well as diabetes - all major risk factors for dementia.
While these latest findings confirm a strong connection between abdominal obesity and risk of dementia and Alzheimer's disease later in life, further studies are needed. The findings were published in the Annals of Neurology, a journal of the American Neurological Association.
According to the Alzheimer Society of Canada, 1 in 11, or about ½ a million, Canadian adults over the age of 65 have Alzheimer's disease or related dementia. Women make up 72% of all cases of Alzheimer's disease in Canada.
