My mother in law takes Aricept and Ebixa together, and has done so for several years. I cannot say whether it has improved things, we have never noticed any difference , she was prescribed Aricept many years ago, and then when we heard of someone in our Alz. group being prescribed both my husband asked, and mother in law was put on both. Maybe by still being on the meds. it has slowed down the progress of the disease, rather than make any improvements. She is now in a nursing home, unable to communicate properly, doubly incontinent, is only mobile when walked with a carer, cannot weight bear on her own, has pureed food, cannot feed or drink by herself, is totally reliant on others, but she has been like this for 2.5 years, actually looks physically ok for a 86 year old, maintains a good weight because we ensure that she gets lots of food and drink, usually a family member is present at mealtimes, (not breakfast) M in law was officially diagnosed with Alzheimers over 10 years ago.
