Dark Triad is the name of the evil that afflicts Donald Trump.

A doctor named Frank George posted on social media that Donald Trump's behavior is typical of people suffering from frontotemporal dementia (FTD), a type of neurological degeneration quite different from Alzheimer's, but still a form of dementia. Abrupt mood swings and genuine belief in lies are said to be some of the indicators of FTD. The media reported on Dr. George's assessment.

This journalist has a particular interest in neurological or psychiatric illnesses and has an excellent source in the field. Fearful of persecution on American soil, since she travels frequently to the United States, our source preferred to remain anonymous (hello, Malu Gaspar!), but stated off the record: Trump is afflicted by the Dark Triad, and not by some form of dementia.

Narcissism, Machiavellianism, and psychopathy essentially make up the Dark Triad. 

Those afflicted by the Dark Triad exhibit impulsivity and emotional insensitivity, as well as an absolute lack of empathy. They tend to manipulate or exploit relationships. They are always seeking attention and more and more power.

 “I’m a very stable genius,” Trump said repeatedly to describe his own ability and mental sanity, even in the face of widespread criticism. This exaggerated assertion of superiority and need for self-affirmation is a classic indicator of narcissism in popular and academic analyses. Narcissism is the most blatant face of the Dark Trial. Phrases like “Only I can fix it” or variations in campaign speeches reflect the belief of being exceptional and indispensable.

Personal insults directed at journalists, such as calling a reporter "piggy" and other direct offenses during press conferences, demonstrate a lack of empathy and interpersonal hostility in confrontational situations. In direct and public interactions with adversaries, Trump has historically used derogatory adjectives and personal motives to the detriment of factual debates, something that linguists interpret as rhetorical aggression. 

Spreading factually incorrect or exaggerated statements about crises, social data, or public safety, even after they have been refuted by concrete facts, is a daily practice of Trump – and also of his Bolsonaro-supporting sycophants. This is not merely a matter of factual error, but a pattern of insistence on narratives convenient to their own position, something that studies on the Dark Triad link to manipulation and social Machiavellianism. 

Let's not forget the strategic repetition of conspiracy theories or allegations of electoral fraud, including the narrative that Joe Biden's election was "stolen"—like Lula's here—despite multiple judicial systems and independent agencies rejecting such claims, a tactic designed to manipulate perceptions and mobilize political support through institutional distrust.

Looking at Donald Trump's behavior is to encounter a typical case of the Dark Triad.
