The Non-Alzheimer Dementias:An Approach to Evaluation and Management

A 72-year-old farmer is brought by his daughter for a comprehensive geriatric assessment. His previous history is unremarkable. The patient reports that he has had vivid visual hallucinations, which he calls "visitors." He becomes frightened and hostile when these incidents occur; on several occasions, he has exhibited violent behavior as persons around him tried to calm him. Although the patient was able to recall each episode in detail, he felt as if he had watched it from a distance and had not been an active participant.
