Before Alzheimer's, my mother was a strong-willed and very competitive woman, although she was very compassionate and willing to compromise. As Alzheimer's began to run its course, the first two traits became more pronounced, while the willingness to compromise often seemed to recede. And on occasion, paranoia and a blinding anger seemed to take over Mom, who often directed her rage at my father.
I have heard about others who suffer from Alzheimer's...
