Weight and Alzheimer’s risk – Tufts

With both Alzheimer’s and dementia in my family, I am interested in all research on the subject.

Tufts reported the following in its Health and Nutrition Letter.

Could a trimmer waistline in middle age help you avoid Alzheimer’s later in life? That’s the suggestion of a study, published in Molecular Psychiatry, from the National Institute on Aging. Researchers analyzed data on 1,394 participants in a long-running study of aging, followed for an average of 14 years, who regularly underwent cognitive testing. A total of 142 participants developed Alz­heimer’s disease during the study.

After adjusting for other factors, each additional point of body-mass index (BMI) at age 50 was associated with an earlier onset of Alzheimer’s of 6.7 months. “Our findings clearly indicate that higher adiposity at midlife is associated with a long-lasting effect on accelerating the clinical course of Alzheimer’s disease,” Madhav Thambisetty, MD, PhD, and colleagues concluded.

The study was not designed to prove cause and effect, however, and it’s not clear whether the association between obesity and Alzheimer’s risk might begin even earlier. It’s also true that newly diagnosed Alzheimer’s patients tend to weigh less than normal, not more.
