QUESTIONS 1 of 2 1 2 Previous Next (M2.PY.17.4867) A 25-year-old female is brought to the physician by her mother who is concerned about her recent behaviors. The mother states that her daughter has been collecting “useless items” in her apartment over the last year. When she tried to persuade her daughter to throw away several years’ worth of old newspapers, her daughter had an angry outburst and refused to speak to her for two weeks. The patient reluctantly admits that she keeps “most things just in case they become useful later on.” She also states that she has felt less interested in seeing friends because she does not want them to come over to her apartment. She has also not been sleeping well, as her bed has become an additional storage space and she must sleep on her futon instead. The patient states that she is sometimes bothered by the messiness of her apartment, but otherwise doesn't think anything is wrong with her behavior. Physical exam is unremarkable.
