My mom has been on Aricept for 14 yrs and was told that she didn't need to be on it any longer. She is 83 and was first put on the medication for her own concern years ago when it first came out. She has a high IQ and reads a lot. After being in the hospital due to a fall, her meds were called into question and Aricept was one of them. I, her daughter, have noticed some depression and short term memory loss. Could the sudden stop of this medicine cause these symptoms?
