So far there are no studies in Minnesota. I have called the U of M several times to ask why or when they might consider it. The problem is that they need a control group ("normal kids") for an accurate study. Not very many people are willing to put their children through it when it benefits no one in their family. I have contacted several hospitals and drug labs and left my name and number to be called when or if they need us. Good luck, and if you hear anything about a study in Wisc. please let me know. I am in the twin cities and willing to drive the 4-5 hours. Also, check Chicago. They are not that far away either.
