Narcissism, or narcissistic personality disorder (NPD), is another cluster B personality disorder. It’s similar to HPD in many ways, but there are a few key differences.
One diagnostic requirement for narcissism is a lack of empathy. People with this condition may ignore how others feel and have little compassion. People with histrionic personality may engage in self-centered behavior, but they don’t necessarily lack empathy.
Another important distinction lies in the reasons for attention-seeking behavior. People with narcissism want to be recognized as special or superior to others. They often lie or exaggerate their own accomplishments in order to receive praise, recognition, or status. People with HPD need the attention of others but may care less about how they get it. They may take on the role of victimhood and allow others to think of them as fragile or helpless.
