Psychology Today lists 9 symptoms of narcissistic personality disorder. In order to have the disorder, one need only display five or more of the symptoms. The list includes:
A grandiose sense of self-importance.
A preoccupation with fantasies of unlimited success, power, brilliance, beauty, or ideal love
A belief that one is special and can only be understood by or associate with special people or institutions
A need for excessive admiration
A sense of entitlement (to special treatment)
A willingness to exploit others
A lack of empathy
An envy of others or the belief that one is the object of envy
An arrogant, haughty behavior or attitudes
More, individuals with this disorder can be easily offended by criticism or defeat. In response, those afflicted with NPD could be angry or scornful. The cause of NPD is not yet well known.
For a clear example of someone likely afflicted with NPD, look no further than President Donald Trump. He constantly displays his feelings of self-importance, his need for excessive admiration, his willingness to exploit others, his lack of empathy, and an arrogant attitude. It could be argued that he displays even more than those five symptoms.
One Donald Trump tweet reads: “Sorry losers and haters, but my I.Q. is one of the highest -and you all know it! Please don’t feel so stupid or insecure, it’s not your fault.”
