The aim of this study is to explore the relationship between the cluster B personality traits (borderline, antisocial, histrionic and narcissistic) and neurological soft signs (NSS). A sample of 3,781 adolescents finished the cluster B personality disorders subscale of the Personality Disorder Questionnaire-4+ (PDQ-4+), the soft signs examinations of the Cambridge Neurological Inventory, and the Barratt Impulsiveness Scale. According to the cut-off scores of PDQ-4+, the prevalence of borderline, antisocial, histrionic and narcissistic personality traits was 4.7%, 3.1%, 2.0%, and 4.4%, respectively. Analyses showed that individuals with borderline personality traits or antisocial personality traits had higher scores on impulsivity and on NSS than those with histrionic, narcissistic, or without cluster B personality traits. These findings suggest that individuals who have cluster B personality traits with high impulsive tendency (borderline or antisocial), may have a nonfocal central nervous system abnormality.
