Narcissistic neurosis is a Freudian diagnostic label describing narcissistic behavior and personality as a mental disorder.
Narcissism is an over-inflated sense of one's own worth. Individuals who suffer from narcissism tend to over-value themselves and under-value or objectify others. They may perceive others not as full human beings with dignity and worth, but rather as objects to be used toward their own end. Narcissistic neurosis describes and categorizes the external presentation of a distressed, but not delusional, narcissistic personality.
Neurosis refers to the behaviors that follow from such distress. These behaviors can range from obsessive/compulsive behaviors to socially antagonistic and abusive behaviors.
In modern psychology, neurosis is no longer used as a diagnostic classification. Instead, the Diagnostic and Statistical Manual of Mental Disorders classifies NPD (Narcissistic Personality Disorder) as one of several personality disorders. Symptoms of the Narcissistic Personality Disorder include social, behavioral, cognitive, and emotional dysfunction. Those suffering with the disorder may also struggle with developmental delays and other adjustment disorders throughout adolescents and adulthood.
