Case 1: Bipolar I Disorder - Acute Manic Episode

Patient Demographics

  • Age: 24 years old
  • Sex: Male
  • Occupation: Graduate student in philosophy

Chief Complaint

Brought by parents: "He hasn't slept in 5 days and spent $15,000 on 'investments' with his student loan money."

History of Present Illness

The patient is brought to the emergency department by his concerned parents. Over the past 10 days, he has become progressively more energetic, talkative, and grandiose. He has been sleeping only 1-2 hours per night but claims to feel "more alive than ever." He has been working on multiple "groundbreaking" philosophy papers simultaneously, convinced he has discovered insights that will "revolutionize human understanding." He enrolled in an online cryptocurrency trading platform and invested $15,000 of his student loan disbursement, believing he has a "foolproof system." He has been posting lengthy philosophical treatises on social media at all hours and making numerous phone calls to professors, publishers, and media outlets to discuss his "world-changing ideas." His speech is rapid and difficult to interrupt. He reports increased libido and admits to multiple casual sexual encounters in the past week, which is out of character. He denies drug use but admits to drinking more coffee than usual. He denies hallucinations. He is annoyed that his parents brought him in, stating "I've never felt better in my life."
