What age must an individual be for an Antisocial Personality Disorder diagnosis if there is a history of conduct disorder?

For a diagnosis of Antisocial Personality Disorder (ASPD), the DSM-5 specifies that the individual must be at least 18 years old. This requirement is rooted in the understanding that ASPD typically arises from a history of conduct disorder, a condition that can only be diagnosed in children and adolescents. Conduct disorder is characterized by a persistent pattern of behavior that violates societal norms or the rights of others.

Following the age of 18, these individuals can then be assessed for ASPD based on their behaviors and patterns observed. The age requirement recognizes that personality disorders, including ASPD, reflect longstanding patterns of behavior that emerge throughout adolescence and consolidate by young adulthood. Therefore, being 18 years old or older is crucial, as diagnoses formulated prior to this age focus on conduct disorder rather than ASPD.
