I agree with hamster-bamster. MI and Austism / asberger has been around long before processed food, pollution etc. Historical records show this. The only thing that changed from society to society was the way these things were viewed and/or treated. Also it has been around long before our modern hectic life-styles. But I am sure every society had its poins that caused stress and anguish for some its members, contributing to depression and debut of MI.
