My Mom has been on Namenda and Aricept which worked wonders for her mood and attitude. The doctor says they are no longer effective in slowing her cognitive decline because she is in the end stages of Alzheimer's. We are trying to decide whether or not to take her off these meds for fear her once difficult and unmanageable personality will return. However, these drugs can subdue appetite and she no longer has an appetite. We are in a quandary as to what to do.
