Insulin Resistance, Type 2 Diabetes Linked to Alzheimer’s
People with insulin resistance and type 2 diabetes appear to be at an increased risk of developing plaques in the brain that are associated with Alzheimer’s disease, according to new research published in the August 25, 2010, issue of Neurology®, the medical journal of the American Academy of Neurology.
Insulin resistance, or the stage before diabetes, happens when insulin, a hormone in the body, becomes less effective in lowering blood sugar.
“Type 2 diabetes and Alzheimer’s disease are two epidemics growing at alarming levels around the world,” said study author Kensuke Sasaki, MD, PhD, with Kyushu University in Fukuoka, Japan. “With the rising obesity rates and the fact that obesity is related to the rise in type 2 diabetes, these results are very concerning.”
The study involved 135 people with an average age of 67 from Hisayama, Japan. The participants had several diabetes glucose tests to measure blood sugar levels. They were also monitored for symptoms of Alzheimer’s disease over the next 10 to 15 years. During that time, about 16 percent developed Alzheimer’s disease.
