Narcissistic Personality Disorder is one of the Cluster B personality disorders, also known as ‘dramatic, emotional or erratic’. The others are Borderline, Histrionic and Antisocial. Narcissistic Personality Disorder is commonly defined as ‘a pervasive pattern of grandiosity, need for admiration, and a lack of empathy’. It is important to note that individuals usually show symptoms across the range of Cluster B personality disorders which makes diagnosis challenging.
Narcissistic Personality Disorder seems to occur more with men (about 75% men 25% women), though this may be an issue of reporting rather than reality.
