Neurobiological substrates of antisocial and borderline personality disorder: preliminary results of a functional fMRI study.

Background: Neuropsychological and imaging studies of patients with antisocial (ASPD) and borderline personality disorder (BPD) are suggestive of frontal lobe dysfunction in these individuals. In normal subjects functional brain imaging has been used to investigate the neuroanatomy of impulse control. There are no such imaging studies in personality-disordered populations.
