3. the disorder's cause is a problem of the adrenal cortex.
4. the symptoms will resolve without medication.

A low ACTH level is an indication that the adrenal insufficiency of Addison's is the result of the pituitary's lack of stimulation to the adrenal cortex. If the ACTH level had been high, the cause would not be the pituitary, but a problem of the adrenal cortex, such as a tumor.
