For Alzheimer's Disease "We started my Dad on Namenda, and by day 2, he was more confused, lost, and irritable than usual, so my Mom stopped it. The doctor asked her to start again, and the same day, he experienced the same side effects, so she stopped. Last week, she decided to try it one more time to make sure. Dad was VERY confused and not easy to take care of. I guess he is just one of those people that can't take this medication. Too bad. It helps so many people."

For Alzheimer's Disease "My mother has been treated with the Exelon (patch) for two years now. Last month she was changed to Namenda. She has become irritable, aggressive/depressed and more confused than before. We are asking the doctor to switch back to Exelon."

For Alzheimer's Disease "My sister has moderate frontal lobe Alzheimer’s. She was extremely agitated, angry, and weepy. She was withdrawing into herself and had little awareness of her surroundings and had difficulty with dressing and toileting. Literally, after the first day of Namenda 20 mg, it was like someone turned the lights on. It’s been 2 months now, and she is aware and able to go for walks by herself; dress herself and play the piano. Her memory and executive function continue to be poor. Nothing short of a miracle. Not sure how long this will last."
