alzheimer's disease
"I have given this to my mother for cognitive help due to Alzheimer's and she has had nothing but challenges, she can't formulate sentences, she's confused, hallucinating.  After only 5 days I took her off.    She had previously tried Aricept but had the same reaction.  I know they are the same family so it wasn't a surprise.  

Now I am frightened of all the drugs."
