As Dr. Sam rightfully states above aka NPD.
However the question asked about N-ism and maybe the question was specifically about NPD but just in case....
This to me hs been one of the minor confusions in my studies of N-ism.
In the DSM bible (Diagnostic Scholastic Manual of Psychiatry 1994) under the umbrella of Narcissism are four personality disorders.
in their pathological manifestation
Anti Social Personality Disorder (APD or ASPD) affects 3% of the population: 75% male
Narcissistic PD circa 1% :75% male
Histrionic PD <1% 75% female
Borderline PD <1% : 75% female
Everyone has negative N-traits. In fact one of the greatest values in understanding N-ism is seeing it in yourself and loathing N-ism so much you are more attentive to improving your own being and annuling your own negative N-traits.
So N-ism is a scale from healthy to pathological. One of my concerns if fully 5% of the adult population are path NNN then what percent are strongly disposed.
People with strong ngative N-traits are also a real pain in the ass and best avoided if you can. So what do you say? for every path. N there must be 3 or 4 strongly disposed so now we are talking another 15-20% of the population.
N-ism is the social disease destroying the fabric of society
Armageddon is not a physical clash between the forces of good and evil but is a spiritual war between the forces of compassion and N-ism!
About 0.7-1% of the population suffers from NPD. Between 50-75% of all narcissists are male. There are no statistics regarding the prevalence of this disorder in other demographic groups (age, ethnicity, etc.)
Yes, it is common to experience narcissism if you have bi-polar, but talk to a medical health professional about it, and you worries.

Certainly AS is more common in males than females, but it can and does appear in females as well. As for passing it on to children, it depends on what causes a particular Aspie's condition; on the whole, however, there does seem to be an element of heredity to the condition. I have high hopes for my children, for instance. ;-)
About 5,000 people are diagnosed with gallbladder cancer each year in the United States, making it the fifth most common gastrointestinal cancer. It is more common in females than males and most patients are elderly.
