I get no help on this from the Memory Clinic. My husband is on 5mg of Aricept which could not be increased as his heart rate would be too slow. He has been on it since February 2021 but it has never seemed to be of any benefit and his dementia is getting worse week by week including having the occasional seizure and now being incontinent at night and occasionally during the day . His confusion is extremely bad now and his walking is very wobbly. He is not aggressive or agitated. Is there any point in continuing with this drug as it has never shown any sign of being of any use to him at all.
