Aricept (donepezil) helps improve brain function by preventing the breakdown of a chemical called acetylcholine. This chemical is crucial for memory, thinking, and reasoning. People with dementia often have lower levels of acetylcholine.

Aricept belongs to a class of drugs called cholinesterase inhibitors, which work by increasing acetylcholine levels to support better brain function. However, it does not change the progression of dementia itself.
