Damning revelations by Dr. Mary L. Trump PhD in her book about her uncle, President Donald Trump, reveal an adult man with the mind of a 3-year-old beset by a range of mental disorders, including sociopathy. 

Donald Trump also believes cheating is a way of life and people are only valued by how much money they have. He's also a sociopath, or a person with an antisocial personality disorder (ASPD).

A practicing clinical psychologist, Dr. Trump has expert credentials in diagnosing and treating individuals experiencing psychological distress and mental illness.

Based on her clinical experience, Dr. Trump said her uncle today "is much as he was at three years old: incapable of growing, learning, or evolving, unable to regulate his emotions, moderate his responses, or take in and synthesize information."

Others who have worked with Trump at the White House describe him in much the same way. These horrible revelations and more about Trump the president are found in Dr. Trump's 211-page book, "Too Much and Never Enough: How My Family Created the World's Most Dangerous Man," now set to be sold on July 14.

Dr. Trump writes her uncle has mental problems and meets all nine criteria needed to be diagnosed as a narcissist. She warns her uncle's mental problems are far more complicated than mere narcissism.

Dr. Trump said her uncle's pathologies are so complex and his behaviors so often inexplicable that coming up with an accurate and comprehensive diagnosis will require a full battery of psychological and neuropsychological tests he won't consent doing, she writes in her book.

She said trying to evaluate her uncle's day-to-day functioning would be "impossible" because "he is, in the West Wing, essentially institutionalized." Donald Trump's immaturity and mental health problems are a danger to the United States. Dr. Trump warned a second term for her uncle "would be the end of American democracy."

Among the signs of Donald Trump's mental problems are his beliefs cheating is a way of life and financial worth is the only gauge for self-worth. Donald Trump also reveres a killer instinct and refuses to admit any responsibility for his failures in life. He always blames others for his failures.

Dr. Trump wrote Donald Trump's own sister, retired federal judge Maryanne Trump-Barry, holds an extremely low opinion of her brother. Trump-Barry once exclaimed her brother has no principles whatsoever.

She exploded when several high-profile evangelical figures began endorsing her brother in 2016. She exclaimed, "What the f**k is wrong with them?"

She went on to say, "The only time Donald went to church was when the cameras were there. It's mind-boggling. He has no principles. None!"
