Are there teenage narcissists

Yes and no. A teenager may exhibit traits of Narcissistic Personality Disorder, BUT a teenager's personality is still DEVELOPING. But just as there are teenage psychopaths who murder, there are teenage narcissists. Many teenagers exhibit narcissistic traits, but this can actually be a normal and healthy phase of growing up. After all, if they don't believe that they can be better, they might collapse into a "loser mentality." The difference shows when they start to enter adulthood. Normal teenagers who were narcissists (which are most of them) will get either bored with grandiOSity or give up Narcissism due to life constraints. Some others will have their narcissism evolve into an ambitious personality, which can still be a good trait. Unfortunately, a number of these teenagers (though relatively very few) will retain pathological narcissism and develop Narcissistic Personality Disorder.
