Diabetes and cognitive functioning

Diabetes and glucose tolerance can have a significant impact on cognitive functioning

In motivation and self control and executive functioning
Many things affect one's ability to exert self-control, but self-control particularly requires sufficient glucose levels in the brain. Exerting self-control depletes glucose. Research has found that reduced glucose, and poor glucose tolerance (reduced ability to transport glucose to the brain) are tied to lower performance in tests of self-control, particularly in difficult new situations.
