Answer to Question 1

A
Patients taking lithium may experience reduced incorporation of iodine into the thyroid hormone, resulting in goiter and hypothyroidism. Administration of levothyroxine or withdrawing the li-thium will reverse both. Increasing the lithium dose will make this worse. Iodine supplements are not indicated. The provider will either order stopping the lithium or administration of levothy-roxine, which will reverse this condition, so referral to an endocrinologist is not necessary.

Answer to Question 2

A
Alzheimer's disease is a disease in which symptoms progress relentlessly from mild to moderate to severe. Medications have not been clearly effective and do not stop the disease progression, although they may slow loss of memory and cognition and prolong independent function. There is no indication that available drugs stop disease progression if begun early in the course of the disease. There is no clearly effective therapy for core symptoms, but associated symptoms such as incontinence and depression may be treated.
