Does anyone have the actual 1994 Duke University Study showing the cost of PD annually? I contacted Neuro-Science for Kids, a wonderful site on the web, last night, and they have already responded saying that they will change the numbers from 500,000 to 1 million people but also want to change the cost from $6 million to $26 million and will if they can document it. So help our cause here. Thanks. Barb
