The US President has psychosis and is “a very sick man”, said Dr Lance Dodes, a former assistant professor of clinical psychiatry at Harvard Medical School who now works for the Boston Psychoanalytic Society and Institute.
“The simple explanation for it, which people don’t want to hear, is that he’s not in control of himself. This is what we mean when we say that somebody is becoming psychotic or is briefly psychotic."
He added: “All of his delusional ideas come up when he is stressed in some way, and then he loses track of reality because it doesn’t fit what he needs to believe.”
Dr Dodes said it was “an extremely dangerous thing” for a position of power to be held by someone who “appears so wantonly unconcerned about the welfare of others and willing to do anything to promote himself”.
Mr Trump was "villainous because of his sociopathy and psychopathy but with a tremendous veneer that he’s extremely good at,” he said.
Nothing that Mr Trump might do would now be surprising to him, including dissolving the US constitution, firing the Supreme Court or starting a nuclear war with North Korea, because such actions would be “consistent” with his previous behaviour”, he added.
The US Congress and allies of Mr Trump need to accept that the President is “an extremely incapable, disordered, sick individual”, he added.
