So sorry Brenda for what you are going through. 
Both of my grandmothers died of Alzheimer's and it's a cruel and unforgiving way to die. My mother took care of my grandmother (actually her grandmother who raised her as her own) until she was placed in a home (mother didnt want to but she had to because taking care of my grandmother (who was actually my great-grandmother) meant mother also had to take care of my real grandmother (Grandma's daughter, who is mentally unstable) and my brother (who is mentally and phyisically disabled). Before Grandma was placed, when she would have moments of lucidity, she would cry because she knew what was happening to her. *Sob* I miss my Grandma!
