Final answer:
Aricept is a medication used to treat Alzheimer's disease by inhibiting the breakdown of acetylcholine, potentially slowing symptom progression. It is usually taken once in the evening.
Step-by-step explanation:
It is important to know that Aricept is primarily used to treat symptoms of Alzheimer's disease. It is a cholinesterase inhibitor which works by boosting cholinergic neurotransmission by preventing the breakdown of acetylcholine, an important neurotransmitter for brain function. Although Aricept doesn't restore lost memories, it may prolong brain neural function and slow the progression of symptoms. Additionally, Aricept can be taken once daily in the evening, just before bedtime.
