late to discussion and loathe to resurrect thread, I wrote something on this topic a while back, seems relevant here:
Does Donald Trump have Narcissistic Personality Disorder? Judging by twitter, many people believe the answer to be yes. However, this is absolutely the wrong question to be asking. If you look at the diagnostic criteria for Narcissistic Personality Disorder you would be right to wonder if it is possible to be a Presidential candidate and not have narcissistic traits. Of course you would have to be preoccupied with success, have a grandiose sense of self-importance, or believe you were special to seek the Presidency. It takes a certain amount of arrogance to be Commander-in-Chief. It is no surprise that people who require excessive admiration or have a sense of entitlement might be drawn to seek the highest office. And, you might be right to believe that others were envious of you. The diagnosis of Narcissistic Personality Disorder is controversial enough, that it was initially slated for removal from DSM-5 (the most recent edition of the psychiatrist’s diagnostic “Bible”), does not feature in the World Health Organization’s International Classification of Diseases, and personality disorders expert
Peter Tyrer has said the diagnosis has “no scientific basis” and that “it is a diagnosis of vanity for doctors and patients alike”.
The armchair diagnosis of Mr. Trump by public figures such as congresswoman Karen Bass (D-Calif.) and former Harvard Medical School Dean Jeffrey Flier is nothing more than a slur wrapped up in psychobabble, a political abuse of a psychiatric label. The most famous example of the political abuse of psychiatric diagnosis occurred in Soviet Russia, where political dissidents were labeled with “sluggish schizophrenia” (a diagnosis that was not used outside the USSR) in order to discredit, drug, and dispense with those whose views the political establishment did not like. Donald Trump’s conduct is divisive and abhorrent, and made no more so by dismissing his rhetoric as the product of mental disorder. If anything, it shifts the dialogue away from his controversial policies, fails to examine why his policies have resonated with so many, and stigmatizes those who live with mental illness.
If there were a genuine interest in determining whether Mr. Trump had a mental disorder we would need to know whether his behavior was simply the result of his position of power and wealth, or how much he was influenced by the response to his provocative statements. We would need to know whether his onscreen persona matched the man behind the cameras. For a diagnosis of personality disorder (the validity of which is already questionable), a psychiatrist would need to establish a pattern of behavior dating back to childhood or adolescence. A change in personality over time would suggest a different diagnosis altogether. Psychiatrists never consider just one possible cause for someone’s behavior – they must consider how biological, psychological and social factors influence a person’s actions. A psychiatrist would also need to consider the effects of another medical illness – for example neurosyphilis, traumatic brain injury, heavy metal toxicity, Alzheimer’s Disease, fronto-temporal dementia, cerebrovascular disease and rarities such as the
brain sagging syndrome and
Fahr’s disease, can all affect personality and behavior – as well as the effects of drugs or alcohol. Finally, not every action we don’t understand is the result of mental illness, nor is everyone we don’t like mentally ill. An armchair evaluation does not allow for a full assessment of the individual and instead provides only a snapshot of a person in a setting where they are under close observation – a fact which itself is known to alter behavior.
Rep. Bass’s call for Mr. Trump to undergo a psychiatric evaluation implies that mental illness should be a disqualification for the Presidency. Abraham Lincoln and Woodrow Wilson – two of the most highly ranked Presidents in the history of the Unites States – are believed to have suffered from depressive illness. One study found that as many as
49% of Presidents between 1776 and 1974 suffered from mental illness. A diagnosis of mental disorder should not in itself be a bar to political office. Psychiatrists have no special ability to determine the fitness of an individual for the Office of the Presidency. Instead, we live in a democracy and rely on the electorate to decide. To do otherwise would be an affront to the democratic process. Mr. Trump’s fitness for the Presidency is a matter for the American People, and not for psychiatrists.
