Packing on even a few extra pounds in midlife can increase the risk of developing dementia, such as Alzheimer's disease, by 70% or more, Swedish researchers reported Monday.
Earlier studies had shown an increased risk from being obese, but the new research reported in the journal Neurology is the first to show that simply being overweight is enough to increase the risk.
"Our results contribute to the growing evidence that controlling body weight or losing weight in middle age could reduce your risk of dementia," co-author Dr. Weili Xu of the Karolinska Institutet in Stockholm said in a statement.
Xu and her colleagues studied 8,534 twins over the age of 65 in the Swedish Twin Registry. The participants' heights and weights had all been measured 30 years earlier. Among the elderly twins, 350 had been diagnosed with dementia and 114 with possible dementia.
