Found that living in high density pollution postal codes was
significantly correlated to autism

Higher maternal exposure to pollution during pregnancy was
associated with greater odds of her child saving autism

Big question: Where they lived during 3rd trimester?
Pollution is rising and children with autism are increasing
Rise in air pollution

Fluoride in the water
Autism is associated with immune functioning
Drinking tap water could be linked to autism
Fluoride is universal

Broadening the definition of autism

All disorders are originated by the brain
◊
Watch child brain waves, not their actions
Most diagnostics are based on pure observation, not brain
testing

Estimated that 1 in 6 children suffer from a developmental disorder

Giving a bacteria, have mercury in it
Kids who got MMR were more likely of getting autism

Authors withdrew because methodology was not sound/reliable

Document Summary
Prevalence- 2000- 1 in 166, 2010 1 in 68. Extent to which other explanations can be ruled out. Found that living in high density pollution postal codes was significantly correlated to autism. Higher maternal exposure to pollution during pregnancy was associated with greater odds of her child saving autism. Pollution is rising and children with autism are increasing. Drinking tap water could be linked to autism. Estimated that 1 in 6 children suffer from a developmental disorder. Most diagnostics are based on pure observation, not brain testing. Kids who got mmr were more likely of getting autism. Gene sequencing- trying to find out the genetic behind the disease o o o o o o o o. What info would be helpful to decide whether these results are valid? o. Generalized- 3 people can"t account for an entire population. Identify children at-risk for learning disabilities in kindergarten.
