Question

Quizplus · Accepted Answer

The dexamethasone suppression test is used to diagnose depression and involves administering a low dose of the steroid dexamethasone, which should suppress the release of cortisol, a stress hormone. People with depression who fail the test continue to show high levels of cortisol, indicating that their stress response is not being properly regulated. High levels of dopamine (B) are associated with certain mental illnesses like schizophrenia, but not depression. Low levels of norepinephrine (C) and low levels of serotonin (D) are both associated with depression, but not specifically with the dexamethasone suppression test.
