Untreated hyperactive tendencies create a whole cycle of problems. " This is Trump. It limits not only his intellectual development, but these problems mean that as an adult he also can’t listen to other people. He can’t think properly. Because Trump does not understand, he therefore has to retreat to name-calling or going to his base to whip up a frenzy of activity. Donald Trump on a fundamental level does not understand complex issues. This is why Donald Trump always says things such as, “I have the best words,” or “I’m the smartest person, I know things other people don't." Together such comments signal something extremely disturbing... Donald Trump is erotically attached to violence... Trump is unable to manage anxiety. Therefore, he cannot help the American people manage their anxiety." (From an interview with Justin Frank, author of "Trump on the Couch.")
