Research into Attention Deficit Hyperactivity Disorder (ADHD) highlights the significant role of genetics in the development of the disorder. A large-scale family study led by researcher Daniel L. Wechsler suggests that ADHD traits in children are primarily driven by their own genetics by mid-childhood, finding little evidence that parental ‘genetic nurture’—where parental genes influence a child’s environment—plays a significant role at ages five and eight.

In Germany, medical experts estimate that approximately five percent of children and adolescents are affected by the condition, noting that roughly 80 percent of symptoms are linked to genetic factors. The disorder impacts brain networks responsible for executive functions, such as task initiation and impulse control. Because there are no specific biomarkers like blood tests, diagnosis remains a clinical process involving interviews with children, parents, and educators, alongside psychological testing.
