People with Early Alzheimer’s Disease May Be More Likely to Have Lower BMI
Studies have shown that people who are overweight in middle age are more likely to develop Alzheimer’s disease decades later than people at normal weight, yet researchers have also found that people in the earliest stages of Alzheimer’s disease are more likely to have a lower body mass index (BMI). A current study examines this relationship between Alzheimer’s disease and BMI.
The study, published in the November 22, 2011, print issue of Neurology®, the medical journal of the American Academy of Neurology, examined 506 people with advanced brain imaging techniques and analyses of cerebrospinal fluid to look for biomarkers for Alzheimer’s disease, which can be present years before the first symptoms begin. The participants, who were part of the Alzheimer’s Disease. Neuroimaging Initiative, included people with no memory problems, people with mild cognitive impairment, or mild memory problems, and people with Alzheimer’s disease.
The study found that in people with no memory or thinking problems and in people with mild cognitive impairment, those who had the Alzheimer’s biomarkers were also more likely to have a lower BMI than those who did not have the biomarkers.
