I was recently viewing a documentary about a Canadian mother of an autistic boy.  In the documentary she was video taping her son from the time he was diagnosed with autism until he became an adolecent. His doctor did a some research studies on the boy and discovered that autistic children have a antibiotic-resistent bacteria in their stomachs. The doctor put this child on a powerful antibiotic called Vancomycin and after a week the boy's autistic behavior patterns changed significently!  Unfortunately this was only for a short time due to the strength of this antibiotic. This could mean that a cure for autistic will soon be invented.  I really hope so!
