No. 2: Reckless Driving and Traffic Accidents ADHD makes it hard to keep your attention on a task, so spending time behind the wheel of a car can be hard. ADHD symptoms can make some people more likely to speed, have traffic accidents, and lose their driver’s licenses. No. 3: Marital Trouble Many people without ADHD have marital problems, so a troubled marriage shouldn’t necessarily be seen as a red flag for adult ADHD. But there are some marriage problems that are likely to affect the relationships of those with ADHD. Often, the partners of people with undiagnosed ADHD take poor listening skills and an inability to honor commitments as a sign that their partner doesn’t care. If you’re the person with ADHD, you may not understand why your partner is upset, and you may feel you’re being nagged or blamed for something that’s not your fault.
