A person suffering from an antisocial personality disorder is often referred to as a sociopath. There, a professional psychologist, Dan P. McAdams, provided a psychological profile of Trump for the purpose of assessing the potential impact of Trump's personality on his possible presidency. A narcissistic personality disorder is defined as a personality "characterized by exaggerated feelings of self-importance, an excessive need for admiration and a lack of empathy for others."

They refer only obliquely to a possible narcissistic personality disorder by characterizing Trump's behavior as "grandiose" in nature - - but without any further explanation.
