KEY POINTS: ADHDers are not motivated by importance, rewards, and consequences as neurotypicals are. ADHDers operate with a high-octane, interested-based nervous system. The intense emotionality that can accompany ADHD is often misdiagnosed as a mood disorder. Hyperactivity is an outward expression of the hyperarousal on the inside, and is often present in ADHDers without the "H" as well.
