I don't understand this, why would hyperactive people be given meds that stimulate them?
Because the ADHD brain is underaroused. It stays in alpha or theta during activities most people would be producing beta waves. It is like being half asleep, or in a trance state. Read this:

Think about way people act when they have to stay up much later than usual, and they are trying really hard to stay awake. Some people will start talking more loudly, or running around and acting silly to stimulate themselves so they can stay alert. Other people will just get very quiet and slow to react to things.
ADHD is a misnomer. It's not really an attention disorder, and it's not really a hyperactivity disorder. The underlying problem is disinhibition. The inhibitory systems of the brain don't work as well. So it makes you more impulsive and easily distracted. Impulsivity can manifest in a lot of different ways, not just hyperactivity.
