I think the rise of ADD, ADHD, LD, dyslexia, and all of the other alphabet soup syndromes are just a rise in the number of square pegs being jammed into round holes. Some kids have exceptional mathematical ability and are weak with language. Others are good at language but fumble with numbers. Most are balanced between the two. School seems to be designed around the idea that everyone learns at the same speed using the same techniques at the same age, and everyone who fails to fit this model must therefore have some sort of "problem".
