ADD vs ADHD & Types of ADHD
For educational purposes only — not medical advice. Always consult a qualified healthcare provider. For adults 18+.
“Is it ADD or ADHD? What are the types?” The labels confuse almost everyone. This guide clears it up in plain language and explains what today's terms actually mean.
Why 'ADD' became 'ADHD', the three presentations (inattentive, hyperactive-impulsive, combined), how they differ, why presentation can change, and what the labels do and don't tell you.

For educational purposes only
This guide is educational information about ADHD and neurodivergence — it is not medical advice, diagnosis, or treatment, and it is not a substitute for assessment and care from a qualified professional. It does not diagnose ADHD, autism, dyslexia, or any condition. Only a qualified clinician can diagnose a neurodevelopmental condition — if you recognise yourself or someone you love in these pages, see a doctor or qualified specialist for a proper assessment. Neurodivergence is a difference, not a deficit, and this guide is written with that respect. If you are struggling emotionally or in crisis, you are not alone: in the US you can call or text 988 (Suicide & Crisis Lifeline), and in an emergency call 911.
