ABSTRACT
This chapter provides a case of a 30-year-old shop assistant who presents to the emergency department requesting that they remove the microchip from her brain. She says that this chip was implanted into her brain some weeks ago in order that aliens could control her mind. She has previously been diagnosed with paranoid schizophrenia and has had a number of previous admissions to psychiatric hospitals, the majority of which have been involuntary admissions. There is no family history of mental illness. She is currently living with her parents who are supportive of her. She describes how the aliens put impulses into her mind which she feels compelled to act upon. She denies any hallucinations but during the interview appears to be responding to unseen auditory stimuli. She has little insight and does not accept that a relapse of her mental illness could be responsible for her current difficulties. There is no abnormality upon physical examination.
