In going public with his bipolar disorder diagnosis in June 2018, Kanye West described his illness as his “superpower.” This touched a nerve — as have his erratic public behavior, his high-profile support for President Trump, and most recently, his insistence that he was misdiagnosed and therefore has stopped taking his medication.

On Dec. 15, he tweeted: “I cannot be on meds and make watch the throne level or dark fantasy level music,” a reference to two of his celebrated albums, “Watch the Throne” and “My Beautiful Dark Twisted Fantasy.”
