People with early evidence of Alzheimer’s disease are more likely to be underweight than people who don’t have this type of dementia, a new study suggests. “Weight loss may be a manifestation of the disease process progressing,” said Eric Vidoni, lead author of a study appearing in the Nov. 22 issue of Neurology. “This may be further evidence for body-wide or systemic changes associated with Alzheimer’s disease ... and it certainly supports the idea that Alzheimer’s disease-related changes could be silently occurring, i.e., a ‘preclinical’ phase.”
