Antisocial Personality Disorder (ASPD) is characterized by a pervasive pattern of disregard for, and violation of, the rights of others beginning in childhood or early adolescence and continuing into adulthood. Individuals with ASPD often display deceitfulness, impulsivity, irritability, aggressiveness, irresponsibility, and a lack of remorse for harmful actions. This disorder is associated with elevated rates of substance use, criminal behavior, and interpersonal conflict, yet presentations can vary widely in severity—from chronic law-breaking to more subtle patterns of manipulation and emotional detachment. Effective treatment emphasizes risk management, behavioral regulation, accountability, and the development of prosocial behaviors, often within structured, consistent therapeutic frameworks.
