Main Objective: To evaluate the efficacy of donepezil on cognition (MMSE) in patients who are currently being treated with memantine, and are switched to donepezil because treatment with memantine is lacking efficacy or is not well tolerated ;Secondary Objective: To evaluate the effects of donepezil on other clinically relevant measures including behaviour (NPI), physician and caregiver satisfaction/ease of use, global function (CGI-I), social behaviour (Caregiver Diary), safety and tolerability in this patient group.;Primary end point(s): Mini Mental State Examination (MMSE): The MMSE is a brief test to assess the cognitive status of the patient.
