A psychiatrist who edited a provocative book about President Trump’s mental health said Monday that there were signs he was “unraveling” as pressure from the Russia probe increases on his administration.

Dr. Bandy Lee, who has also briefed congressional Democrats about the president, told NPR’s On Point Monday that "we are seeing some of the signs of a crisis mode" amid indictments of Trump associates like Paul Manafort.

“I’ve been using the word unraveling,” Lee, on the faculty at the Yale School of Medicine's Law and Psychiatry Division, told guest host Ray Suarez. “What happens is that one's ability to keep oneself together is falling apart.”

Those signs include a loss of touch with reality and impulsiveness — see, for example, claims that his recorded voice in the Access Hollywood tape wasn’t his voice, and retweeting violent imagery.

Lee’s book, “The Dangerous Case Of Donald Trump,” came out in October 2017, and featured 27 mental health professionals “assessing” the president.

The book has received newfound attention after a second controversial book, “Fire And Fury” by Michael Wolff, relayed troubling allegations about the president’s fitness for office — many in Trump’s inner circle doesn’t think he’s mentally fit for the job, Wolff writes. (The White House has aggressively pushed back on the veracity of the Wolff book.)

To be sure, diagnosing someone without meeting them, much less treating them, is a taboo in the medical profession. The American Psychiatric Association’s so-called “Goldwater Rule” prevents psychiatrists from offering a professional opinion on someone they haven’t treated.
