The etiology of psychopathy: A neuropsychological perspective

While there is no universally accepted cause of psychopathy, there are basic biological patterns in brain dysfunction observed in individuals who display psychopathic tendencies. These individuals show significant impairment in specific regions of the brain, particularly the orbital frontal cortex (OFC). Such abnormalities exist in brain areas most involved in impulse control and behavior inhibition. There are also significant environmental factors that the majority of these individuals have in common. For example, a strong correlation exists between attachment disorder and anti-social personality disorder (ASPD). Finally, the differences between ASPD, psychopathy, and sociopathy are considered. While these terms are often used interchangeably, there are clear differences between these psychopathologies.
