alzheimer's disease
"My mother has taken Namenda twice now. The first time she was so confuse after a week I stopped giving it to her. She has gotten worse over the years and for some reason her doctor had given me a new prescription for the same medicine. I tried it for two days and saw my mother become extremely confused so I stop giving it to her. I don't know why he insisted on Namenda after I told him it didn't work the first time."
