My mother is on Aricept and she is doing relatively well. She can remember things a bit better now.  

My grandmother was diagnosed with Alzheimer's disease and has been on Aricept for several years now. She tolerates it very well and is still quite capable of performing the usual functions.  

My father has started taking Aricept recently and it seems to help him a good deal. He is not so confused as he used to be.
