Asperger's Disorder Misdiagnosed as Narcissistic Personality Disorder (NPD)

Asperger's Disorder is often misdiagnosed as Narcissistic Personality Disorder (NPD). In both cases, the patient is self-centered and engrossed in a narrow range of interests and activities. Social and occupational interactions are severely hampered and conversational skills (the give and take of verbal intercourse) are primitive. The Asperger's patient body language - eye to eye gaze, body posture, facial expressions - is constricted and artificial, akin to the narcissist's. Nonverbal cues are virtually absent and their interpretation in others lacking.
