Down syndrome IQ Statistic

This is a really interesting statistic. Since the time when parents starting raising their babies with Ds at home, instead of institutionalizing them, and providing them with early stimulation and intervention the average IQ in the Down syndrome population has gone up 20 points. If your not familiar with IQ scales 20 points in enormous!! It moves you up an entire category- like from severely impaired to mildly impaired.
