While most of those points have citations, some do not. Anyone know what backs up the statement:

"Many cases of underachievement are linked to chronic early ear infections (9 or more in the first three years), with residual effects of auditory sequential processing deficits and attentional problems. Spelling, arithmetic, handwriting, rote memorization, attention, and motivation to do written work are all typically affected."

DS hit everything there except for rote memorization and arithmetic. I'd love to see the studies that go into this statement.
