Case Study:

Ella is $88$ years old and was living at home until very recently. Her children, who visited her regularly, noticed that she was becoming more forgetful. At first, she mislaid objects, and then she began to forget her doctor's appointments. With time, her personality changed, and she became withdrawn. At home, she would forget to turn off the stove or leave the kettle on until it boiled dry. After seeking advice from a gerontologist and social worker, Ella's children placed her in a nursing home with a unit equipped for patients with Alzheimer disease.
