Tufts University Study Finds Another Potential Risk Factor for Developing Dementia and Alzheimer's Disease in Women

A hormone derived from visceral fat called adiponectin may play a role as a risk factor for development of all-cause dementia and Alzheimer disease (AD) in women, according to a study published Online First by the Archives of Neurology, one of the JAMA/Archives journals. The number of people affected by dementia worldwide is estimated to double over the next 20 years from the current number of about 36 million people, the authors provide as background information in the article. AD is the most common form of dementia. The authors write that data suggest an association between insulin resistance and inflammation, hallmarks for type 2 diabetes, and development of dementia. "An additional potential factor that may contribute to the onset of AD and all-cause dementia is adiponectin. Adiponectin is a hormone derived from visceral fat, which sensitizes the body to insulin, has anti-inflammatory properties, and plays a role in the metabolism of glucose and lipids."
