Those with ADHD in childhood committed their first crime before 15
Significantly younger than controls at the time of arrest
Men with ADHD have an earlier onset of crime
What is the age dependant decline in offending?
Declining rates of ADHD with age in offender populations
Findings of an overrepresentation of ADHD in adolescent and young adult offender

Vaa 2014 - ADHD increases risk for violations of road traffic rules compared to those without ADHD
Mohr-Jensen 2016 meta analysis - assault, theft, drugs were among the most frequent for contact with the CJS
What was Young’s key findings from their research in the Scottish Prison?
Examined effects of ADHD on critical incidents of aggression
Self report ADHD and antisocial personality disorder
Results were higher in those with ADHD symptoms
But SD was much bigger in those with ADHD symptoms
