Why are so many adults diagnosed with ADHD late in life?

Educational only: This page is for general education—not personal medical advice, diagnosis, or treatment. See a licensed clinician for your situation.

Short answer

Childhood ADHD was often missed—especially in girls, high achievers, and inattentive types without hyperactivity. Adults seek answers after burnout, job changes, or parenting when old coping strategies stop working.
