Diabetes Raises Alzheimer's Risk: Researchers

By    |   Tuesday, 26 May 2015 01:13 PM

Two more studies have linked diabetes to Alzheimer’s disease, adding to the growing scientific evidence that high blood-sugar levels can affect the brain in ways that increase the risk for certain forms of dementia.

Neither study is definitive and more research is needed, experts say. But doctors argue that the findings provide new reasons for people with diabetes to closely control their blood sugar and manage it through diet, exercise, and medication, the Wall Street Journal reports.

The first study, by Washington University in St. Louis, mice with artificially raised blood sugar had higher levels of amyloid beta proteins in the brain — a key risk factor for Alzheimer’s disease.

The second study, conducted at the University of Pittsburgh, found middle-aged people with Type 1 diabetes had significantly more brain lesions, and slower cognitive function, than those without the disease.

Suzanne Craft, professor of gerontology and geriatric medicine at Wake Forest Baptist Medical Center, said the good news about the findings is that for people with Type 2 diabetes, exercise may be a promising way to reduce the risk of Alzheimer’s.

Exercise helps metabolize insulin and protect the brain against amyloid proteins to boost connectivity between neurons and memory formation.

Diabetes affects some 29 million people in the U.S. and can cause heart disease, blindness, and death.
