Even just a cursory glance over social media can tell you that a lot of people think Donald Trump is "crazy," or "insane," or even an actual narcissist. But Allen Frances, MD, who wrote the diagnostic criteria for narcissism , thinks that we shouldn't be so quick to point to mental illness when it comes to Trump. In response to a New York Daily News article on Trump's possible narcissistic personality disorder that has been making the rounds on Twitter, Dr. Frances weighed in, saying that to speculate about Trump's mental health is to entirely miss the point. Dr. Frances responded to another Twitter user who asked for his thoughts on the matter, tweeting that "constantly saying Trump's crazy [is] wrong & misses point." "He doesn't meet DSM Narcisssistic criteria (I wrote them)," he wrote. "Its [sic] worse - he's bad, not mad."
