“Antisocial” can refer to antisocial behavior, which is a pattern of actions causing harm or distress to others (like noise, vandalism, or threats), or Antisocial Personality Disorder (ASPD), a mental health condition marked by a persistent disregard for others’ rights and well-being. While antisocial behavior describes harmful actions, ASPD is a diagnosis of a personality disorder characterized by a pervasive pattern of deceitfulness, impulsivity, aggression, and a lack of remorse.Â
