As a former psychologist myself, I must agree with those professionals who diagnose Trump to be psychopathologically conspicious, he has a very destabilised personality and imo serious memory handicaps that indeed can be seen as symptomatic for and in combination with certain forms of personality disorder. And that is just the observation of the status quo in his personality as it displays itself in his behavuiour. A complete clinical diagnosis would necessarily include a biographical anamnesis.
In my view, he is ill, and suffers some kind of personality disorder breeding a complex syndrome of symptoms, that probably unfolded and developed from childhood on (the latter may sound like a joke, but lets face it, often these trhings indeed root in the childhood already...
