In a study on the prevalence of attention-deficit/hyperactivity disorder (ADHD) and its association with crash risk among older adult drivers, researchers at Columbia University Mailman School of Public Health found that older adult drivers with ADHD are at a significantly elevated crash risk compared with their counterparts without ADHD. Outcomes included hard- braking events, and self-reported traffic ticket events, and vehicular crashes.
Until now research on ADHD and driving safety was largely limited to children and young adults, and few studies assessed the association of ADHD with crash risk among older adults. The results are published online in JAMA Network Open.
My doctor advised me of it in about 2002.
Here's a study from 2007 just super quick Google search:
