Clinic Notes: Mercury Levels in Children with Autism

Science is a slow process and sometimes it's not a discovery that is made in a study that is important, but a study or studies that can rule out something as a cause. No one knows what causes autism but several recent studies, combined with previous studies, in my judgment have gone a long way in ruling out two causes of autism. Previously, I wrote a blog on a large Mayo Clinic study that found no differences in the frequency of gastrointestinal disorders in children with autism and normal controls. And now from the Mind Institute at UC Davis we have a large sample study that finds that there was no differences between mercury levels in the blood levels of children with autism and a control group. This study, combined with previous studies that found no relationship, tells me that it is time to move on and investigate other variables that have more potential.
