What is it about?
This article addresses how adolescents’ non-clinical ADHD symptoms assessed by themselves, their teachers, parents, and siblings are associated with neuropsychological test performance and whether these associations are influenced by genetic and environmental factors shared between co-twins. We found that teachers' assessments of inattention and hyperactivity-impulsivity seem to be especially relevant, since they were most consistently associated with cognitive test performance.

Why is it important?
These findings give further support to the notion of dimensionality in ADHD symptoms at the population level: normal variation in inattention and hyperactivity-impulsivity is connected to cognitive test performance.
Perspectives
As a clinician working with patients with neurodevelopmental disorders, I found studying these familiar topics in the general population especially fascinating. The same phenomena I encounter in my day-to-day work are present in the general population, just to a milder degree. I think our study succeeded in combining viewpoints from neuropsychology, adolescent psychiatry, and twin research - all thanks to my talented co-authors, without whom this article would never have been possible.
