Recently, these 3 headlines appeared on my iRadar Screens:
♦ Genetics a Cause of Autism in Most Cases: Study
♣ Korean-American Professor Couple Identify Major Cause of Autism
♠ Could multivitamin use in pregnancy protect children from autism?
Yet, the research was entitled:
♦ The Heritability of Autism Spectrum Disorder
♣ Mum’s bacteria linked to baby’s behavior
♠ Antenatal nutritional supplementation and autism spectrum disorders in the Stockholm youth cohort: population based cohort study
And, the papers covered the following data:
♦ The examiners mathematically re-analyzed decades-old Swedish registry information that strengthened the association with genetic factors. About the findings the lead author has admitted, “our results do not give any information about specific genes or other direct causes. It only informs us that genes are important…. our study cannot shed any light” on the reason for higher rates.
♣ This was published in Nature, entitled, Maternal gut bacteria promote neurodevelopmental abnormalities in mouse offspring. “The couple found that certain bacteria in the mother’s digestive tract can lead to having an autistic child. Furthermore, they found the exact brain location linked to autistic behaviors, which can be used to find a cure for autism.” Mice are not men.
♠ Using a similar Swedish cohort as the first study, authors reviewed supplementation with multivitamins, iron and folate. They concluded that, “Maternal multivitamin supplementation during pregnancy may be inversely associated with ASD with intellectual disability in offspring.”
All of the information first appeared in reputable journals. The stories took a turn through leading health and science magazines, and finally popular media announced theories as if they were dogma. Often, autism research is subject to the ‘telephone game’, resulting in overstated and oversimplified claims masquerading as explanations for complicated medical concepts.
Nevertheless, these investigations represent clues, directions to be pursued, possible new treatments and even prevention. It’s so confusing because they document only baby steps in this scientific puzzle.
Rather than view these studies as disparate, an alternative perspective could be something like:
If autism is the result of a susceptible individual (genetic study) affected by an environmental stress (mouse study), then utilizing a metabolic intervention (third study) might make sense.
