Obesity linked to up to 27% lower risk of death in dementia patients

A study involving over 4,500 older adults revealed that individuals who were overweight or obese at the time of dementia diagnosis had a 16% to 27% lower risk of death compared to those with normal weight, according to ScienceDaily Health.

Researchers from Columbia University Mailman School of Public Health and NYU School of Global Public Health published their findings in the Journal of Alzheimer's Disease, suggesting that extra energy and muscle reserves might help patients endure the physical effects of dementia.

The study challenges common perceptions about weight and health, as obesity is typically linked to serious conditions like heart disease and diabetes and is a known risk factor for developing dementia in middle age.

Despite these risks, the research indicates that once dementia develops, higher body weight may be associated with better survival outcomes, a finding that the researchers say is unlikely to be due to bias.

These results emphasize the importance of proper nutrition for people living with dementia and suggest that body weight at diagnosis could provide insights into patient prognosis.
