Alzheimer's disease because of developing plaques in the brain.
New researchpublished in the August 25, 2010, issue of Neurology®,
the medical journal of the American Academy of Neurology says this
comes about when insulin becomes less effective in lowering blood sugar,
the hallmark of diabetes.
“Type
2 diabetes and Alzheimer’s disease are two epidemics growing at
alarming levels around the world,” said study author Kensuke Sasaki, MD,
PhD, researcher 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.”

Hisayama, Japan who were monitored both for sugar levels and symptoms of
Alzheimer's disease over a period of 10 to 15 years.

Japan. Autopsied brains after these folks died revealed the plaques
and tangles.

Those
who had abnormal results on three tests of blood sugar control had an
increased risk of developing plaques. But the study did not find an
association specific to diabetic factors and tangles in the brain,
because non-diabetics have similar tangles.

“Further
studies are needed to determine if insulin resistance is a cause of the
development of these plaques,” said Sasaki. “It’s possible that by
controlling or preventing diabetes, we might also be helping to prevent
Alzheimer’s disease.”
