My 94 year old father was diagnosed with Mixed Dementia. He is calm and reasonable, patient, and loving. We are about to be dropped from the roles of the Memory Clinic, because I have not given him the tablets, and that is because I've not found in on-line researches that it has helped with any, but behavioral, issues. Also it seems difficult to drop once begun. (When I ask doctors for advice, they will not say definitively that it has improved their particular patients, only that it is recommended.) I do not want him sedated. He is already sleepy much of the time, and this drug appears to have a sedating effect. Please do let me know if it works for your loved ones in which the cognitive powers are still good, (although memory and awareness of world events is much compromised). I fear any side effects, and do not see from anything I read that it prolongs cognitive function over all, but, rather, just calms restless and unhappy behaviors. I know the science behind this drug, protecting channel blockers and all, but want to know from the experience of this group!
