Many experts often call Alzheimer’s type 3 diabetes because of its link to insulin resistance. Some studies suggest diabetes may be a risk factor for developing Alzheimer’s. And other studies show that high blood glucose can lead to dementia. “Among older adults with diabetes, there is also an association between low blood sugar (hypoglycemia) and dementia, say researchers at the University of California, San Francisco (UCSF) in a new study published in the Journal of the American Medical Association. The UCSF researchers found that the relationship between dementia, Alzheimer’s, diabetes, and hypoglycemia is mutual.”
