My 75 year old father has narcissistic personality disorder and coming up on a year ago decided to write his "manifesto". At first it was a hobby and seemed therapeudic but over time he has become obsessed with it to the point where he rarely leaves the house and has dropped other activities he used to do. The content of his writing consists mostly of his political and religious opinions that are (for me) embarassing, ill-informed, shocking, and paranoid. He recently withdrew all his and my mother's cash from the bank because he believes the government is about to collapse. He also believes when he finishes the book that he will be invited on various talk shows and even run for president. I have offered to help him self publish the book as an ebook as an attempt to get him to finish the book. He may be close to being done. Either way I'm concerned. He will be disappointed when the book flops or if he continues writing. It has decreased his own quality of life and my mother who he has dragged into his delusions of grandeur by having her typing his hand-written notes for hours every day because he refuses to learn how to use a computer. I have tried to get him to find a hobby or other things to enjoy but his narcissism convinces him that he doesn't have time for "ordinary" things because he's going to save the world with his book. Mother and I have accepted that his narcissism will not go away and is only getting worse as he gets older. It is sad because he is bored and sad and looking for validation. Before the book he paid some poor graduate student he met at the golf course to have lunch with him twice a week so they could "research" some invention he thought was going to make it big. Instead the student would nod and listen to my father's grandiouse ideas about how they ought to invent something and a month later the guy stopped showing up and stopped answering his phone. I can't blame him. What do you do with an aging narcissist?
