Antisocial personality disorder is characterized by a long-standing pattern of disregard for others' rights through behaviors such as violating laws, deceiving others, impulsiveness, aggression, and lack of responsibility. Symptoms typically begin in childhood or teenage years and continue into adulthood. Those with ASPD show no remorse and have difficulty maintaining relationships, work, and family obligations. It is commonly comorbid with substance abuse, anxiety, and other personality disorders.
