  During the last fifteen years of my mother's life she suffered from Alzheimer's disease (老年癡呆癥) .Until then she had been a bright,cheerful woman deeply interested and involved in the world around her. I would go home to visit her in Virginia and she would look at me in a puzzled way and ask, "Who are you?" I would answer, "I'm your son. ”"Where do you live?" She would ask. "In California," I would tell her. "Isn't that interesting?" she would say, "I have a son in California."

  She seemed simply forgetful and confused at the beginning of the disease,but later on she would go through periods of intense anxiety. She would pace through the house she had lived in most of her life crying uneasily that she wanted to go home. Or she would leave home and wander away if she were un?attended for a short time.

  Hoping to please her and put her mind at ease I would take her for a drive,visiting sites where she had lived as a child. In the yard of the house on the hillside in Shipman I sat in the car and admired the view of the old oaks and the long green lawn. I pictured my mother there was a little girl playing with the pet lamb she had been so fond of. I looked to her for some response. She shook her head and said, "I want to go home."

  Over the years I have decided that what my mother was calling home was not a place,but a time. I suspect it was a time when she was much younger,when her children were still around,when her husband was still vigorous and attentive.

  Watching my mother's suffering set me wondering where I would have gone in mind if someday I couldn't find home and wanted to go there. In this family we tend to be longlived and we grow fuzzy (糊涂的) -minded as the years go by. At eighty I have already noticed some alarming symptoms. My doctor says the forgetfulness is only natural and that it comes with age. Still the fear of Alzheimer's is haunting there. Someday if and when I become even more cloudyminded than I am now,unable to drive and unable to tell you where "home" is,my dear son,I expect I will ask you to take me home. I know you will do your best to find the place I need to be. I leave these notes for your guidance.
