59. That is all good information, but it is common for a person

to have both disorders.

You're right that pathological narcissism would be worse, since it doesn't respond to any standard treatment. (And these individuals very rarely go for treatment, since they consider themselves perfect.)

How common are borderline and narcissistic personality disorders?

According to the largest study ever conducted on personality disorders (PD) by the U.S. National Institutes of Health (NIH), 5.9% of the U.S. population has BPD (Grant et al. 2008) and 6.2% has NPD (Stinson et al. 2008). As some people fit both diagnoses, about 10 percent of the U.S. population has BPD and/or NPD.

Of the people meeting the criteria for a BPD diagnosis, 53 percent were women and 47 percent were men (Grant et al. 2008). Of the people meeting the criteria for NPD, 62 percent were men and 38 percent were women (Stinson et al. 2008).

Your partner could have either disorder—or both. Almost 40 percent of people with one of these disorders also have the other, according to the NIH study (Grant et al. 2008; Stinson et al. 2008). Many more people have traits of a PD, but not the full disorder. Therefore, the number of people with some of these problems may be even higher.
