This week two new publications reported on systematic reviews for nutritional and sensory treatments for ASD. This means the existing research was sorted, summarized, scrutinized and evaluated. They found insufficient evidence to show any dietary or nutritional therapy was effective, but sufficient evidence that sensory integration therapy helps people with ASD. In light of new data on heavy metals found in baby teeth, it’s important to remember that chelation is NOT effective and dangerous. While “insufficient evidence” does not rule out these interventions forever and always, lots more needs to be done in these areas to conduct rigorous experiments that don’t have any major shortcomings so they hold up to scrutiny.
Two studies recently add to an ever growing literature around undiagnosed siblings of individuals with autism. While in autism features there is evidence of the “broader autism phenotype” in female siblings, there is no evidence of elevated sensory symptoms in those with a brother or system with autism. The more we understand about the psychological and psychiatric features of siblings with autism, the more they can be supported to deal not only with their siblings challenges, but with theirs as well.
