I seem to be hearing alot of Dr's giving patients ativan. I am not Dr but ativan or generic lorazepam is anxiety medication. I was with mom at her Dr today and her first Dr was overmedicating her with alot of crap. Dementia is his specialty and he started her on donepezil a few weeks ago and it seemed to help somewhat. Today he also ordered Namenda XR (memantine HCI) He said it works as a booster to the donepenzil. Again I am not a Dr but maybe this will help. Since seeing this Dr I am hoping my mom will at least maintain where she is at.
