Conversation: The conversation between human and AI assistant.
[|Human|] My sister has severe rages, abusive tendencies, and appears disorganized. She has had a long history of escalating quickly. She is unable to carry on a normal conversation without becoming angry.  Her attitude is "Its all able me". she lacks empathy and appears to act jealous of others. She has never been married nor has she had children.  However, she wants others to think she knows more than the person she converses with. It seems the older she becomes the worse she is.  Am I correct in saying that she could have a personality disorder. If so what personality disorder could it be? I thought maybe on the line of Narcissism.
[|AI|]  Hi, Yes, she may be having a personality disorder, though she would also need assessment for other mental disorders as they are often co-morbid with personality disorders. As to the type of personality disorder, some of the traits that you mentioned are consistent with a diagnosis of narcissistic personality disorder. However, it is usual for people to have traits of more than one personality disorders, thus having a mixed personality disorder. She should be assessed for other personality disorders as well, especially borderline personality disorder. Best wishes.
