Amphetamines are "medication" in the loosest sense. The pathophysiology of the underlying condition is ill-defined, and most users of amphetamine-like drugs get the same focus-enhancing effects regardless of "condition". These drugs are dangerous, of questionable therapeutic benefit, and are schedule 2 (or banned in many countries) for a reason.

They are over prescribed, especially to below average performers who want a boost. Everyone wants to believe they are actually really really smart but have a "condition" which makes them underperform. Don't worry this little pill will "fix" your brain.
