mild cognitive impairment
"Our mother was put on 10mg Aricept (started with 5mg) and after 2 months, had a completely different personality and had lost 16 pounds. (She started at 114 - lost almost 15% of her body weight.)  It was AWFUL!!  She had no appetite, was depressed, angry, and just a completely different person.  I have read many terrible reviews now that we have been through this experience.  Stay away from Aricept."
