Diabetes Doesn't Seem to Affect Alzheimer's Disease Progression

Conditions that cause problems maintaining normal blood sugar levels -- such as glucose intolerance, insulin resistance and type 2 diabetes -- don't appear to be linked to specific signs of Alzheimer's disease, new research indicates. "When older folks develop dementia, it's usually from a host of factors [including Alzheimer's disease and hardening of the arteries]. Our study has shown that when older people with diabetes have dementia, it's not through Alzheimer's disease pathology," said senior study author Dr. Richard O'Brien. http://www.nlm.nih.gov/medlineplus/news/fullstory_139144.html
