ABSTRACT Some persons with antisocial personality disorder (ASPD) are terrorists, and some terrorists suffer from ASPD. Many terrorists demonstrate diagnostic features of ASPD without possessing the actual disorder. Individuals with ASPD have some characteristics in common with terrorists such as social alienation, early disturbance of social development process, narcissistic rage and hostility/violence. In this paper, the characteristics of terrorists with ASPD and link between terroristic attitude and ASPD are examined in order to provide a more profound basis for forensic psychiatric assessment and treatment of this subcategory of terrorists. Furthermore, it is hypothesized that it is useful to consider the terrorist with ASPD as a distinctive category. It was concluded that more research is needed into the specific neurobiological and psychosocial correlates of this phenomenon in order to provide adequate treatment and prevention programs.
