From
MSNBC, news of another study suggesting that "a heavier weight in middle age may mean a higher risk of
dementia later in life. ... It's possible [that] excess fat cells have some direct effect on brain function. For example, some studies suggest
the 'hunger' hormone leptin, which is produced by fat cells, plays a role in learning and memory. And although these study participants were in generally good health, disorders like
elevated blood pressure and
diabetes could act as a bridge between
high BMI and poorer cognitive function. Thickening and hardening of the blood vessels supplying the brain can contribute to dementia ... Similarly, diabetes may harm cognition by either leading to artery disease or via direct effects of
the hormone insulin on brain cells."
