Mrs. S, born in 1913, was brought in by her husband in September 1989. He was very worried about her failing memory and poor balance which he had noted for about six months. The year before that she had lost 20 pounds. This he ascribed to poor dentures so that she could not chew even though she had a good appetite and was hungry. She was able to run her household and to do crossword puzzles. Because of her poor balance she had fallen several times.
