Inflammation may be main driver behind autism, a new study suggests.
Researchers compared the brains of eight children with the developmental disorder and eight children without it.
They found the parts of the autistic children's brains that are crucial to working memory and attention - areas that are impaired in people who have autism - had unusually high levels of a molecule known to trigger inflammation.
The team, led by Tufts University School of Medicine in Boston, Massachusetts, says the findings suggests that drugs that target anti-inflammatory proteins could one day be an effective treatment for autism.
Oh like encephalitis, which can be caused my vaccines.
