Journalists and commentators have become armchair psychiatrists and are increasingly wondering if Donald Trump has some kind of personality affliction, or whether he's "crazy."

The Washington Post on Monday published a column by Eugene Robinson asking, "Is Donald Trump just plain crazy?"

"During the primary season, as Donald Trump's bizarre outbursts helped him crush the competition, I thought he was being crazy like a fox," wrote Robinson. "Now I am increasingly convinced that he's just plain crazy."

Tuesday on MSNBC, "Morning Joe" host Joe Scarborough said he spent the previous day getting phone calls "and everybody was asking me about his mental health… Everybody was calling me saying, 'What's happening with him? What's wrong with him?'"

Questions raised within the news media about Trump's mental balance come after a series of controversies involving the candidate — like his suggestion that Russian cyberhackers should reveal any information they have on Democratic nominee Hillary Clinton, or his back-and-forth this week with the parent of a fallen soldier who has been critical of Trump's campaign.

But some of the psychological analysis predates those incidents.

In three of his recent columns, the New York Times' David Brooks, who is not a licensed therapist, has diagnosed Trump's mental state. Last week he said Trump "appears haunted by multiple personality disorders."

In mid-July, Brooks wondered if Trump is a narcissist with "unstable self-esteem."

In June, Brooks suggested Trump has an "inability to identify and describe emotions in the self."

That same month, the Atlantic published a 9,000 word article exploring the "Narcissism, disagreeableness [and] grandiosity" of Trump.

There is at least one time where Trump turned the tables, sort of.

During an interview with Fox News' Bill O'Reilly in March, Trump accused the anchor of being "negative" in his coverage of him. When asked why he felt that way, Trump said, "I don't know that. You have to ask your psychiatrist."
