The acute confusional state (delirium) is a common presentation for a wide variety of medical conditions in the elderly. This paper reports a prospective study of acute confusion in elderly people admitted to general medical services in two acute care hospitals in Edmonton, Alberta. Eighty patients were studied, ranging in age from 65-91. ⋯ Confusion was a sensitive sign of physical illness, and its resolution accompanied recovery. A diagnosis of the cause of the confusion state could be made in 22 of 24 cases. These findings support the aggressive investigation and treatment of acute confusion in the elderly.
