Source: # Understanding ADHD (Chapter 27) *From the book – Chapter 27: ADHD and Neurodiversity* ## ADHD Attention-Deficit/Hyperactivity Disorder: persistent inattention, hyperactivity, and impulsivity that impair functioning at home and school. Not simply “naughtiness”; it involves neurodevelopmental differences. The three words in the name are not a personality insult. Inattention is losing the thread of a task that is not urgent. Hyperactivity is a body that will not sit because sitting is expensive. Impulsivity is the act arriving before the brake. All three must show up in more than one place — home and school, or home and work — and they must cost something real. ADHD is linked with differences in the brain messengers dopamine and noradrenaline. That is a sketch, not a blood test. Diagnosis is a history plus observation, usually across settings, by a clinician who knows development.
