How long is Aricept (donepezil) effective for the alzheimers?

It varies. It could be early as three weeks from the beginning of the medication to make the medication effectively. Remember, it simply slows down the progression, not cure. I would stop the medication when the person is becoming more chair bounded or bed bounded or no longer accepting to feed. Remember Aricept (donepezil) deal with three main components - behavioral, functional and cognitive.
Differs by symptom. Aricept (donepezil) increases a chemical in the brain known as acetylcholine. This slows functional decline early in dementia and helps behaviors late. I recommend continuing it as long as possible if there are no adverse effects.
Mild-sev. FDA approved it for mild-mod-severe, but few doctors continue it toward the end. Once the patient is so severe that memory and attention are no longer helped by it, there is no reason to continue it. Of course it only extends functionality, it does not modify the disease itself.

Are there any more effective options to treat alzheimer's besides donepezil?

Not yet. Donepezil and related medications, rivastigmine and galantamine (galantamine hydrobromide) all have about the same level of mild benefit.

Nothing great, but.. The basic meds such as donepezil, galantamine, (galantamine hydrobromide) and rivastigmine are mediocre interventions, and memantine, is best when used with the others. Sometimes, early on, a medical food such as axona or cerefolin-nac might be useful, but neither is a lasting solution. Sorry, we just don't seem to be getting newer meds for dementia. Read more...
