Recently a long term study has found that a rise in blood sugar levels was tied to memory decline.

Researchers assessed cognitive function in 5,189 people, average age of 66 and had tested their blood sugar levels using HbA1c, a test that accurately measures blood glucose levels over weeks or months.
