For Alzheimer's Disease I have been on Aricept 5mg at bedtime for 2 months . Was diagnosed just after I turned 60 this summer . I started having trouble finishing a sentence , my mind would go blank . I knew something was wrong . Had the blood test APOE test and scored 3/4 out of 4/4 . Aricept seems to be helping me think clearer . The side effects of Diarrhea first happen in the beginning , but went away . Don't give up on this medication . Its helping me .

For Alzheimer's Disease My mother has been taking it for one month and her dementia - which was mild - has gotten worse. She is confused and thinks that my brother lives with her. She was taking samples as she cannot afford the medicine
