A nurse is teaching a client who is newly diagnosed with Alzheimer's disease and their family about newly prescribed medications for Alzheimer's disease. Which statement by the client indicates the teaching was effective?

Choice A reason: Alzheimer's medications do not target energy levels. Fatigue may be a symptom of the disease or other comorbidities, but energy improvement is not a therapeutic goal of these drugs. Choice B reason: There is currently no cure for Alzheimer's disease. Medications may manage symptoms or slow progression but cannot reverse the disease. Choice C reason: These medications do not restore lost memories. They may help preserve cognitive function but cannot recover previously lost information. Choice D reason: This is the correct understanding. Cholinesterase inhibitors and NMDA receptor antagonists can help slow cognitive decline in some individuals with Alzheimer's disease.
