Edit: I should also note this from the article This is why if you are an adult and you suspect you have ADHD you should at least talk to a doctor about it don't ignore it!Breaking down the numbers further, the researchers estimated that between 41 percent and 49 percent of the car accidents involving men with ADHD could have been avoided if they had been taking their medication as prescribed.
