Abdominal fat at middle age linked to dementia

Abdominal fat at middle age associated with greater risk of dementia — Study confirms that obesity is associated with lower total brain volume – Researchers from Boston University School of Medicine determined that excess abdominal fat places otherwise healthy, middle-aged people at risk for dementia later in life. Preliminary findings suggest a relationship between obesity and dementia that could lead to promising prevention strategies in the future.

Fluctuating blood pressure increases cerebrovascular disease risk
