Dr John Zinner, the former head of the Unit on Family Therapy Studies at the National Institute of Mental Health, made the claim in an interview with Yale forensic psychiatrist Bandy X Lee for Raw Story.
During the interview, that was published on Tuesday, Dr Lee asked the psychoanalyst what he thought of the claims made by the president's niece Dr Mary L Trump about her uncle's mental health.
Dr Zinner, who researched narcissistic disorders during his time at the NIMH told Dr Lee that he agrees with the diagnosis.
Dr Zinner did not diagnose the president with anything specific in 2017, but he is now among 37 other mental health professionals who have speculated on the state of Mr Trump's mental health, following the release of The Dangerous Case of Donald Trump: 37 Psychiatrists and Mental Health Experts Assess a President, edited by Dr Lee.
Many of the long-standing claims made by Dr Zinner and Dr Lee about the president's mental health have drawn judgment from some in the psychiatric establishment.
The American Psychiatric Association states it is unethical for members to speculate about the mental health of a public figure they have not personally examined, under the Goldwater rule.
In 2016, after multiple journalists asked for the organisation to comment on Mr Trump's mental health, the American Psychological Association president Susan McDaniel said that the ruling does apply to public figures and added that she and her colleagues could not comment.
The Independent has contacted the Trump campaign for comment.
