What is the link between high blood sugar levels and Alzheimer's disease?

ANSWER

High blood sugar has been linked to higher levels of protein pieces called beta amyloid. When these clump together, they get stuck between the nerve cells in your brain and block signals. Nerve cells that can't talk to each other is a main trait of Alzheimer's.
