A surprising study of more than 4,500 older adults found that people who were overweight or obese when diagnosed with dementia had a 16% to 27% lower risk of death than those at a normal weight. Researchers suspect that extra energy and muscle reserves may help patients survive the disease's toll on the body, although the reason for the survival advantage remains unclear.
