Study: How stress affects the brain

SAN DIEGO (KUSI) –  New Harvard Medical School study examines how regular exposure to stress can affect our brains.

The study published in the journal Neurology said people with high levels of the hormone also had lower brain volume than those with regular cortisol levels.

Cortisol, produced by the adrenal glands, helps the body respond to stress. It can also help reduce inflammation, control blood sugar and blood pressure, regulate metabolism and help with immune response. High cortisol levels can be caused by stress, medical conditions or medications.
