Narcissistic personality disorder is characterized by an inflated sense of self-importance, need for admiration, and lack of empathy. It is caused by factors such as overindulgent parenting and low self-esteem. Symptoms include believing oneself to be special, requiring excessive admiration, taking advantage of others, and having trouble maintaining relationships. Treatment may involve psychotherapy or hospitalization for severe cases.
