Multiple Choice

In Cushing's disease, cortisol is typically elevated. Which option best reflects this?

The key idea is that Cushing's disease causes hypercortisolism due to excess ACTH produced by a pituitary adenoma. This leads to elevated cortisol levels, which is why the statement "cortisol elevated" best reflects the condition. The other options don’t fit: ADH isn’t the primary driver of this disease, aldosterone elevation points to a different disorder (mineralocorticoid excess), and a decrease in cortisol would contradict the hypercortisolic state characteristic of Cushing's. Elevated cortisol directly captures the hormonal signature of Cushing's disease.
