STAT+: ADHD medication linked to less impulsive behavior, crashes, and crime

A study tracking nearly 250,000 Swedish people using ADHD medication for 14 years found that these treatments can reduce risks of traffic crashes, injuries, and criminal behavior — and that conclusion remained true even as more girls, women, and adult men received a diagnosis.

The study arrives as providers in the United States contend with twin realities: ADHD medication prescriptions are skyrocketing — largely thanks to telehealth and diminishing stigma — while medication shortages are imperiling people’s access to these critical treatments.
