My 92 year old husband was diagnosed with MCI in 2019. It has progressed to moderate Alzheimer's. We declined neuropsych testing because his neurologist got a bit rattled when I asked if the testing was for research or to help the patient. Our primary physician referred him to a geriatrician and all the good stuff has come from that practice. He never took Aricept, but for several years has been using the daily transdermal patch rivastigmine and I, and others in my caregiver support group whose spouses use it, believe it has slowed down decline. He is content and most happy listening to classical music and talking to or being with our sons and their families ( and me!). Ask about the patch - can't hurt to ask . No side effects at all for my husband.
