Delusional disorder — MCQs

A 24-year-old woman presents with her husband to a physician with the complaints of fever, cough, and cold for the past 5 days. When the physician asks her if she has taken any medication for her symptoms, she answers, “My husband and I possess great powers to heal sickness. So I tried to cure my symptoms with my power. However, due to some divine cause, it did not work this time, so I thought I should seek medical advice”. Upon asking her husband about this, he says, "I have always had an immense ability to heal others through my powerful thoughts. It is only after I married her that she came to realize the powers within herself.” The physician examines her and prescribes appropriate medications for her symptoms. A year later, the woman presents again to the same physician with a cough and cold for 2 days. The physician asks her why did she not use her ‘power’ this time. She replies, “I separated from my husband 6 months ago, and I no longer believe that I nor my husband had any special power.” The woman denies any hallucinations, mood disturbances, and socio-occupational impairment to date. Which of the following conditions was this patient most likely suffering from?
