One thing nobody wants? A president whose mental health is deteriorating. Mental health experts are starting to claim just that: That President Donald Trump is on the brink of a mental breakdown, and it’s coming quickly

1. He’s volatile

Professionals expressed their concerns about Trump’s “marked signs of volatility.” Trump’s potentially volatile behavior is best explained by the ongoing, escalating tensions between Trump and North Korean leader Kim Jong-un.

The University of Melbourne’s daily news website, Pursuit, asked: Could personal insults trigger war? According to the site, “It’s Donald Trump’s erratic response to rising threat levels that has many people worried.”

Next: Trump’s coping mechanism may be worrisome.

2. Violence is his coping mechanism

Bandy X. Lee, a forensic psychiatrist at the Yale School of Medicine, brought up Trump’s “attraction to violence as a means of coping.” One example of this is when Trump went on a retweeting spree of anti-Islam videos that originated from a U.K. far-right group.

“President Trump … [used] Twitter to promote a vile, extremist group that exists solely to sow division and hatred in our country,” Sadiq Khan, London’s mayor said, “As the mayor of this great diverse city, I have … called on Theresa May to cancel her ill-judged offer of a state visit to President Trump.”

3. They’re nervous about his ‘psychological instability’

Lee wrote an opinion letter to The New York Times detailing his concern with President Trump’s mental health. Lee, the editor of The Dangerous Case of Donald Trump: 27 Psychiatrists and Mental Health Experts Assess a President, wrote to represent the mental health professionals who voiced their issues.

In the statement, Lee noted that he and the rest of the experts chose to come forward to warn against the president’s “psychological instability and the dangers it poses. We now number in the thousands.”

4. He contradicts himself

Trump has made multiple comments about mental health and gun ownership. Following the fatal February 14th attack on a Florida high school, the president promised to “help secure our schools, and tackle the difficult issue of mental health,” The New York Times reported.

Yet, just last year, Trump signed a bill that stopped a regulation aimed at keeping guns out of the hands of the severely mentally ill. It’s not clear that it would have prevented the Florida or Las Vegas massacre shooters from acquiring guns. Many find it contradicts his statements on mental health.

5. He’s lost touch with reality

In addition, Lee argues Trump has lost touch with reality.

Trump issued a unique video apology for an Access Hollywood tape that exposes one of the most controversial things he’s ever said. “Anyone who knows me knows these words don’t reflect who I am,” he said. “I said it, I was wrong, and I apologize.”

Shortly before his inauguration, Trump told a Republican senator that he wanted to investigate the recording but he’s continued to suggest that the voice on the tape isn’t him.

Next: He can be unpredictable.

6. He exhibits unpredictable behavior

Trump exhibited said unpredictable behavior in November when President Trump called Senator Elizabeth Warren “Pocahontas” during an event honoring Native American veterans.

“You were here long before any of us were here,” he said. “Although we have a representative in Congress who they say was here a long time ago. They call her Pocahontas.” The crowd remained completely silent. Trump spoke immediately in front of a portrait of President Andrew Jackson, whose administration has been criticized for its unfair treatment of Native Americans.

They’ve formed a coalition

Lee told CNBC that “All agree that he’s dangerous,” and have formed a group called the National Coalition of Concerned Mental Health Experts. Their website calls for lawmakers, mental health professionals, and anyone interested in learning more to register for their forum or view it.

They express their view that “Trump’s mental state presents a clear and present danger to our nation and individual well-being.”

Next: The one thing the mental health professionals wouldn’t do.

For ethical reasons, the experts wouldn’t diagnose Trump

Ordinarily, Lee and the other contributors carry out a routing process for treating what they call “dangerous people.” The President of the United States is a different matter. Professionals found that “the power of the presidency and the type of arsenal he has access to should raise greater alarm, not less.”

Contributors urged the public and the lawmakers of the U.S. to ask for an evaluation of the president. Psychology Today followed suit, stating, “Donald Trump has defiantly flipped the presidential script, with chaos and deliberate combativeness the new norm.”
