Thinking themselves "above the rules that the rest of us work to", sufferers committed extreme, cynical and violent crimes to satisfy their needs, Ms Daynes added.
With "a great feeling of entitlement", they felt entitled to other people's respect, admiration and money and could be "very callous", Ms Daynes added.
She said: "It is good to think highly of yourself - but for these people it is out of control. It has gone off the scale."
The Mental Health Foundation website says at least three of the symptoms of the disorder need to be present for diagnosis.
"Like other personality disorders, narcissistic personality disorder is a controversial diagnosis," it adds.
"At present there is no consensus as to its causes or treatment."
