What is an accurate statement regarding donepezil (Aricept) for Alzheimer's disease?

Donepezil, known by the brand name Aricept, is a medication commonly used to manage symptoms in individuals with Alzheimer's disease. It is classified as a cholinesterase inhibitor, which enhances the levels of acetylcholine, a neurotransmitter that is often deficient in people with this condition. By increasing acetylcholine availability in the brain, Aricept can help improve or stabilize cognitive function, particularly in the earlier stages of Alzheimer's disease.

This means that patients may experience prolonged functioning and improvements in daily activities because the medication targets some of the cognitive symptoms associated with the condition. However, it is essential to note that while Aricept can lead to symptomatic relief and may help patients maintain their level of functioning for a time, it does not stop the progression of Alzheimer's disease nor does it cure it.

The other options present incorrect or misleading information about the medication. For example, Aricept does not have a curative effect, and like many medications, it can have side effects, which may include gastrointestinal issues and sleep disturbances. Additionally, it does not decrease cognitive function; in fact, its role is to help improve it to some extent. Understanding these facts helps clarify the appropriate use and expectations for patients prescribed with donepezil
