general dx question?

[The People]

Nats if you look in the DSM (it is on line) you will see that NPDs often have a high degree of anxiety. Most often actually. Underneath the narcissism there is a great deal of insecurity. I have worked with some, both as clients in a non-t role, and also as a co-worker. It can be tough. They truly don't understand why you don't see the world from their perspective. I believe that some of them can change to a degree if there is enough intelligence.

Is the person actually forgetting what they have said or done or is it a defense mechanism. I don't see that as part of an NPD. Don't remember learning that it is an aspect of their condition.
