If it feels like more children and teens are being diagnosed with anxiety or ADHD than a decade ago, the data backs that up. A large nationally representative study tracking U.S. children ages 6 to 17 found that clinically diagnosed anxiety rose from 8.2% in 2016 to 12.8% in 2023—with the sharpest increases among adolescents and girls. ADHD diagnoses have followed a similar long-term trend, with CDC survey data showing that roughly 11 to 15% of U.S. adolescents now carry an ADHD diagnosis, and researchers pointing to both rising awareness and improved screening as contributing factors.
Why anxiety and ADHD often overlap
One of the more consistent findings in recent research is how often these conditions occur together. Among children diagnosed with anxiety, a large majority also have at least one co-occurring condition—most commonly ADHD, followed by depression and behavioral difficulties. That overlap matters clinically: a child who is inattentive in class may be dealing with ADHD, an anxiety disorder, or both, and the right treatment plan depends on getting that distinction right.
Girls, in particular, are more likely to be diagnosed later than boys—often because ADHD in girls tends to present as inattentiveness or daydreaming rather than the hyperactivity that's more readily recognized in younger boys. Anxiety can mask or mimic ADHD symptoms as well, which is part of why a thorough evaluation, rather than a quick checklist, matters so much.
What to watch for
- Ongoing difficulty with focus, organization, or following multi-step instructions at home or school.
- Excessive worry, avoidance of school or social situations, or physical complaints (stomachaches, headaches) tied to stress.
- Sleep disruption, irritability, or a noticeable change in mood or behavior lasting several weeks or more.
- Teachers or caregivers independently raising similar concerns across different settings.
When to seek an evaluation
A single stressful week rarely warrants concern. But when symptoms are persistent, interfere with school, friendships, or family life, or have lasted more than a few weeks, a formal psychiatric evaluation can help clarify what's going on and rule out overlapping conditions. Early evaluation matters—both anxiety and ADHD respond well to treatment, and the earlier a child receives an accurate diagnosis, the sooner a treatment plan tailored to their specific needs can begin.
Treatment approaches vary by child and by diagnosis, and often include some combination of behavioral strategies, school-based supports, and medication management, guided by ongoing follow-up rather than a one-time visit.
