A 72-year-old man is newly diagnosed with Alzheimer's disease. The patient's daughter asks the nurse how her father's medication is going to help him. What will the nurse explain in layman's terms?
A) "The drugs work by increasing acetylcholine (ACh) levels in the brain and slowing the progression of the disease."
B) "The drugs work by crossing the blood–brain barrier and cure the disease in the brain."
C) "The drugs work by increasing ACh levels in the brain and reverse the progression of the disease."
D) "The drugs work by crossing the blood–brain barrier and decreasing ACh levels in the neuromuscular junctions."
A
Feedback:
Acetylcholinesterase inhibitors that cross the blood–brain barrier are used to manage Alzheimer's disease by increasing ACh levels in the brain and slowing the progression of the disease. Decreasing ACh levels in the brain does not slow the progression, reverse the progression, or cure the disease. Decreasing ACh levels at the neuromuscular junctions has no effect on Alzheimer's disease.
