Older people who are thinner or are losing pounds quickly are at an increased risk of developing dementia, especially if they started out overweight or obese, according to a new study.
A new study has found that the risk of dementia increases in older people who are thinner or are rapidly losing weight, especially if overweight or obese in their younger days.
The research is published in the May 19, 2009, print issue of Neurology, the medical journal of the American Academy of Neurology.
How Changing Light Could Help People With Dementia, Other Diseases
Periods of blue-light, like daylight, produced from the blue-white lamp prototypes developed by GE scientists, could help people suffering from dementia and other health problems.

The research found that people with lower body mass index (BMI) scores at the beginning of the study were 79 percent more likely to develop dementia than those with higher BMI scores.
In addition, those who lost weight over the study period at a faster rate were nearly three times more likely to develop dementia than those who lost weight more slowly over time. This result was more pronounced in those who were overweight or obese to start; those with a BMI of 23 or higher had an 82-percent reduced risk of developing the disease compared to those who were normal or underweight.

"Our finding suggests that losing weight quickly in older age may be an early sign of dementia," said study author Tiffany Hughes, PhD, MPH, who is with the University of Pittsburgh School of Medicine but conducted the research while she was a doctoral student at the University of South Florida.
