Pharmacological strategies for the management of the antisocial personality disorder

Abstract

Introduction: Antisocial personality disorder (AsPD) is a pervasive pattern of violation of others' rights, related to the concept of psychopathy. AsPD is stable over time from adolescence, with evidence of conduct disorder (CD) before 15 years. DSM-5 included a specifier 'with limited prosocial emotions' (LPE), which characterizes adolescents with higher developmental vulnerability to develop AsPD. Despite being relatively frequent with considerable societal impact, AsPD is a difficult-to-treat condition with high comorbidity rates and poor evidence for effective pharmacological interventions.

Areas covered: We conducted a narrative review and searched PubMed up to September 2022. We included RCTs and naturalistic studies evaluating pharmacological interventions on AsPD in adults, including those with comorbid substance use disorder or psychopathic traits. Evidence in youths with CD, callous-unemotional (CU) traits and aggression were also reviewed, exploring the role of CU traits as moderators of response.

Expert opinion: Psychosocial interventions are the first option, with possible improvement of CU traits, beyond behavioral and affective symptoms, particularly if implemented early during development. Limited information, based on low-quality studies, supports the pharmacological options. Second-generation antipsychotics, lithium, anti-epileptic drugs, and stimulants are first-line medications, according to different target symptoms. Developmental pathways including ADHD suggest a specific role of psychostimulants.
