How is Namenda used for Parkinson's? My mom has issues with low blood pressure and passing out at times when it goes really low. Her neurologist wants her to take Namenda titration and seemed to feel it would help her blood pressure issues. She is on Carbadopa/Levadopa, Aricept, Quetiapine, and I'm just concerned about adding another med with side affects. She does seem to be more confused, but the passing out has me more concerned. The doctor tried putting her on blood pressure increasing meds, but it went too high and took some time to come down even after quitting the meds. I am afraid to put her on another medication. I've also heard that Aricept only works for about 6 months and then it really doesn't make a difference. Thank you for any suggestions.View Thread
