People with Type 2 diabetes may be at increased risk for developing dementia as they age, several studies have suggested. Now researchers say the higher odds may be linked to life-threatening drops in blood sugar, called hypoglycemia, usually caused by excess insulin.
A long-term study of thousands of older patients with Type 2 diabetes in Northern California found that those who had experienced even one episode of hypoglycemia serious enough to send them to a hospital were at higher risk for developing dementia than diabetic patients who had not experienced such an episode. With each additional episode, the risk of developing dementia increased, the study found.
The findings, to be published on Wednesday in the Journal of the American Medical Association, are significant given the high rates of Type 2 diabetes around the world, and the expectation that dementia rates will increase as the population ages.
