Consider two diseases: Disease A and Disease B. Children with Disease A are described as being “excitable” and “precocious,” at risk of being “overstimulated.” Thus, they are unable to balance “academic, intellectual, and physical growth.” [Schuster, 116] Children suffering from Disease B, on the other hand, are “active, restless, and fidgety” and have difficulty “sustaining attention to tasks, persistence of effort, or vigilance.” [Barkley, 57] At first glance, the symptoms of the two diseases in children seem oddly similar. Yet these are two wildly unique diseases that have never overlapped in time.
