My father suffers with mixed dementia - Lewy Body and Vascular and was lucky enough to be placed on Excelon, which he has benefitted from for approx 3 years. It has been suggested that he might get a further 'honeymoon period' if he changed to Aricept but I am not too sure whether this would be a good move as my father is particularly sensitive to any changes in drug therapy. Has anyone had any experience of changes (good or bad) with anti-dementia drugs? I thought the three main drugs were basically the same or do they act in different ways? If anyone has any advice or has faced a similar dilemma, please let me know. Thank you!
