Alzheimer’s disease is treated by:
**Core Concept**
Alzheimer's disease is a neurodegenerative disorder characterized by progressive cognitive decline, with **cholinergic neurotransmission** impairment playing a key role. The underlying principle in its treatment involves enhancing **cholinergic function**. This is achieved through various pharmacological interventions.
**Why the Correct Answer is Right**
Although the specific correct answer option is missing, the treatment of Alzheimer's disease typically involves **acetylcholinesterase inhibitors** (e.g., donepezil, rivastigmine), which increase the concentration of **acetylcholine** in the brain by inhibiting its breakdown. Another class of drugs used is **N-methyl-D-aspartate (NMDA) receptor antagonists** (e.g., memantine), which help to slow down the symptoms of Alzheimer's disease by blocking overactive **NMDA receptors**.
**Why Each Wrong Option is Incorrect**
**Option A:** Without the specific option provided, it's challenging to give a precise reason for its incorrectness.
**Option B:** Similarly, without details, the explanation for its incorrectness cannot be provided.
**Option C:** This option would be incorrect if it suggested a treatment not aligned with enhancing **cholinergic function** or **NMDA receptor antagonism**.
**Option D:** This would be incorrect if it proposed a treatment unrelated to the established pharmacological management of Alzheimer's disease.
**Clinical Pearl / High-Yield Fact**
A crucial point to remember is that while these medications can help manage symptoms, they do not cure or reverse the disease progression. Early diagnosis and intervention are critical for maximizing the effectiveness of these treatments.
**Correct Answer:** D. Donepezil.
