[摘要]：An 89-year-old man was brought to the emergency department by his wife and son for an evaluation of changes in cognition and personality. Six months earlier, he began to require help managing finances and operating his computer. He had poor memory for recent events, had difficulty expressing himself, and had become increasingly irritable. He also exhibited unusual behaviors, such as eating a banana peel, pouring milk onto the table, and undressing immediately after getting dressed. He began to have difficulty walking and occasional urinary and fecal incontinence. During the course of several months, he became unable to dress, bathe, use the toilet, or walk independently. |
