What Is a Narcissistic Personality Disorder?
3. Causes
As with so many other mental issues, it is very difficult to determine the cause of narcissistic personality disorder. The issue is very complex but we have been able to identify some factors that are associated with the condition. One such factor in genetics, as some people might simply be born likely to develop the disorder.
Another potential cause is the environment the patient grew up in. Some people that faced persistent and excessive criticism when they were young may go on to develop the disorder. In other cases, the patient will have been surrounded by persistent praise with little to no effort to challenge their flaws.
