Individuals suffering from narcissistic personality disorder do not tolerate being ignored well, according to thenarcissisticlife.com. However, ignoring them may be the best way to escape their neediness.
The main symptoms of narcissistic personality disorder include craving admiration and attention, exaggerating one's own achievements and talents, striving to win no matter what it takes, having fast mood swings and setting unrealistic goals, according to WebMD. While there is no lab test to confirm narcissistic personality disorder as a mental illness, a psychiatrist may use other tests to confirm the diagnostic.
For persons in a relationship with a narcissist, ignoring him may be the last resort after trying other methods of dealing with the disorder, including understanding its roots and maintaining a positive outlook. An ignored narcissist may continue to try to establish contact for a long time.
