Many experts use the criteria in the Diagnostic and Statistical Manual of Mental Disorders (DSM-5), published by the American Psychiatric Association, to diagnose mental conditions. This manual is also used by insurance companies to reimburse for treatment.
DSM-5 criteria for narcissistic personality disorder include these features:
- Having an exaggerated sense of self-importance
- Expecting to be recognized as superior even without achievements that warrant it
- Exaggerating your achievements and talents
- Being preoccupied with fantasies about success, power, brilliance, beauty, or the perfect mate
- Believing that you are superior and can only be understood by or associate with equally special people
- Requiring constant admiration
- Having a sense of entitlement
- Expecting special favors and unquestioning compliance with your expectations
- Taking advantage of others to get what you want
- Having an inability or unwillingness to recognize the needs and feelings of others
- Being envious of others and believing others envy you
- Behaving in an arrogant or haughty manner
Although some features of narcissistic personality disorder may seem like having confidence, it's not the same. Narcissistic personality disorder crosses the border of healthy confidence into thinking so highly of yourself that you put yourself on a pedestal and value yourself more than you value others.

Any honest person (and I do mean HONEST) will have to admit that these are traits which also are exhibited by Barack Obama ad-Dajjal and Hillary Clinton.
But if you want to keep lying to yourself and others, then just pretend they are not.
What would that be called? Associative agnosia, or just plain old denial?
