ADD is a spectral disorder, being that different conditions can cause a range of resultant behaviors, with or without hyperactivity.
Anyone who calls ADD or ADHD a decease has instantly surrendered all credibility in the conversation. There is a huge difference between a disease and a disorder.
Disorders tend to be over-diagnosed, as most people are looking for an excuse to justify bad behavior.
There is no substitute with kids for time and firm and loving resolute support and discipline. I strung those specific adjectives together in that order for a reason. People want to talk about discipline without support, and people want to talk about support without discipline, both are fails. And together they are fails without love and consistency.

PS. You guys are honing your goals in on a more specific focus, which is good and needs to be made to have a worthwhile discussion, IMO. Many questions need to be asked with any disorder being diagnosed. The guideline for further inquiry; if it is a child of reading age and no special learning disabilities to hinder them with this task, can they read a book on their favorite topic for twenty minutes or a half-hour? If they can't, or have trouble digging deeper, further investigation is warranted. Adult abuse, hidden, either sexual, physical, or emotional can cause these symptoms, and even cause a child's reading to lag several years behind standards.
