''Some multiples carry several different eyeglasses, because their vision changes with each personality,'' said Bennett Braun, who directs a unit devoted to treating multiple personalities at the Rush-Presbyterian-St. Luke's Medical Center in Chicago. Dr. Braun reports the case of a young woman who in one personality was colorblind for blue and green, a problem that ended with the successful treatment of her multiple-personality condition. Another woman, admitted to a hospital for diabetes, baffled her physicians by showing no symptoms of the disorder at times when one personality, who was not diabetic, was dominant. A young man was allergic to citrus fruit in some personalities, but not in others.

Research on brain patterns of multiples has produced data of unusual promise. Dr. Braun reports the case of a woman who, at one point in her treatment, manifested four personalities. Brain wave measurements showed each had a distinct pattern of brain function. After her successful treatment, when these four personalities were blended into a single, integrated one, the remaining pattern was still distinct from any one of the previous four.

''The difference between the personalities were significantly greater than normal people simulating other personalities could produce,'' said Monte Buchsbaum, a research psychiatrist at the University of California at Irvine, who collaborated on the study. ''The personalities looked like completely different people.''
