My mother has stage 6 Alz and acts afraid and anxious most of the time. The doctors say that the two prescriptions she takes, Aricept and Namenda, may or may not be keeping the symptoms at bay. It seems almost cruel at times to keep her on these meds to prolong her life when she really has no quality of life anymore. She doesn't know her family. Has anyone had to make the decision to discontinue the meds?
