Narcissism and NPD

Narcissism describes the character trait of self love. The word is derived from a Greek myth. Narcissus was a handsome Greek youth who rejected the desperate advances of the nymph Echo. As punishment, he was doomed to fall in love with his own reflection in a pool of water. Unable to consummate his love, Narcissus pined away and changed into the flower that bears his name, the narcissus. In psychology and psychiatry, excessive narcissism is recognized as a severe personality dysfunction or personality disorder, most characteristically Narcissistic Personality Disorder, also referred to as NPD. Narcissistic personality disorder is characterized by extreme focus on oneself, and is a maladaptive, rigid, and persistent condition that may cause significant distress and functional impairment.
