Study Finds Higher BMI Linked to Longer Survival After Dementia Diagnosis
A 24-year study of 4,523 U.S. adults found that being overweight or obese at the time of a dementia diagnosis is associated with a significantly lower risk of death compared to normal weight. While midlife obesity remains a risk factor for developing dementia, higher body mass index (BMI) at diagnosis may provide protective metabolic reserves against disease-related wasting. Researchers caution that this is an observational association, not a recommendation to gain weight, and emphasize the critical role of nutritional support in dementia care.
