It's doubtful that it would have surfaced to the degree it has if the powerful American Psychiatric Association had not officially named it a disorder in 1990. Just because something responds to a drug doesn't mean it is a sickness. However, the possibility exists that ADD defines a personality type with distinct emotional driven behaviors which contrast sharply with the accepted norm in conventional society. Recent handwriting research has identified the thinking and emotional styles in four quadrants of the brain. This is not to say lack of training causes ADD, only that failure to influence impulse control early on may create more educational problems down the road, giving rise to the need to identify the problem.
ADD is then the culprit.
Facets of brain research have determined how the left and right hemisphere learns - the brain's learning styles. Each hemisphere requires different strategies and instruction techniques to reach and teach each hemisphere. Using multi-sensory stimulation is effective in reaching both brains. A young child's brain is compared to a Pentium chip in the computer before the factory loads the software. Its neurons, pure and of almost infinite potential, represent unprogrammed circuits.
