Aricept is a medication commonly prescribed to treat symptoms of Alzheimer's disease. It works by increasing levels of a neurotransmitter called acetylcholine in the brain, which is important for memory and learning. By enhancing communication between nerve cells, Aricept may help improve cognitive function and slow the progression of symptoms in some patients. The active ingredient in Aricept is donepezil, and it is typically taken once daily. While it can help manage symptoms, it does not cure Alzheimer's disease or stop its progression. Patients should discuss potential side effects and benefits with their healthcare provider.
