Two years before Mom died, my sister, brother, and I began noticing changes in her. Her long-time family doctor would not make a diagnosis, nor would he refer her to a specialist who would. He led us to believe that these changes were a "normal" part of aging. Mom lived alone in the home we grew up in, with my brother and sister nearby. I live 90 miles away. The changes were more pronounced to me, since I didn't see her every day as they did.
