It was quite upsetting to me to see my mother cry during the later stages of her Alzheimer's Disease. Even though I realized it was out of her frustration, it is distressing, especially when you live a long ways away and rarely get to visit.

Mom took several meds to try to stabilize things: anti-depressant, anti-anxiety, etc., especially.

At the end, she would wake up during the night in a rage. I was thankful she was in a facility that specialized in her disease and could handle this. I would not have been able to handle it without my own emotional distress.
