People with Attention-Deficit Hyperactivity Disorder have a vastly higher chance of getting caught up the criminal justice system, according to the first-ever population level study.
Otago University researchers examined a three-year birth cohort spanning from 1992 to 1995, and compared this with health data to identify the 5-7 percent of people with ADHD.
They then looked at criminal records between the group's 17th and 25th birthdays.
Those with ADHD were 2.1 times as likely to be proceeded against by police, 2.2 times as likely to be charged in court, and 2.3 times as likely to be convicted.
Most shocking, was the finding they are nearly five times as likely to be imprisoned, compared to those without ADHD.
