Miss G. is a 62-year-old woman recently diagnosed with cancer. Her doctors asked the psychiatrist to see Miss G. because she appeared depressed, was not eating, and refused to get out of her hospital bed, even to go to the bathroom. On exam, Miss G. said she had worked at a job which required little interaction with others. She said she had never married and did not have any friends. She did not appear bothered by this and said her dog was all the company she needed. She lived in her family’s home after her parents died. Her brother, who lived in another state, rarely heard from her. She reluctantly admitted to feeling depressed. Miss G. was started on Ritalin (a psychostimulant used to treat depression in medically ill patients in part because it works more quickly than antidepressants). The staff working with Miss G. were advised not to try to be too chummy with Miss G. because it made her uncomfortable. Miss G.’s depression responded well to the medication and staff reported improved interaction with her when they maintained a respectable distance.
