Mhh-mhh-mhhn....Makes ya wonder...Is it in the milk???

Is it infant formula that  causes autism, or is it something in the breast milk that fights the weakening of the immune system.?


Although Autistic Disorder is associated with several congenital conditions, the cause for most cases is unknown. The present study was undertaken to determine whether breastfeeding or the use of infant formula supplemented with docosahexaenoic acid and arachidonic acid is associated with Autistic Disorder. The hypothesis is that breastfeeding and use of infant formula supplemented with docosahexaenoic acid/arachidonic acid are protective for Autistic Disorder.Methods

This is a case-control study using data from the Autism Internet Research Survey, an online parental survey conducted from February to April 2005 with results for 861 children with Autistic Disorder and 123 control children. The analyses were performed using logistic regression.Results

Absence of breastfeeding when compared to breastfeeding for more than six months was significantly associated with an increase in the odds of having autistic disorder when all cases were considered (OR 2.48, 95% CI 1.42, 4.35) and after limiting cases to children with regression in development (OR 1.95, 95% CI 1.01, 3.78). Use of infant formula without docosahexaenoic acid and arachidonic acid supplementation versus exclusive breastfeeding was associated with a significant increase in the odds of autistic disorder when all cases were considered (OR 4.41, 95% CI 1.24, 15.7) and after limiting cases to children with regression in development (OR 12.96, 95% CI 1.27, 132).Conclusion

The results of this preliminary study indicate that children who were not breastfed or were fed infant formula without docosahexaenoic acid/arachidonic acid supplementation were significantly more likely to have autistic disorder.

Docosahexaenoic acid and arachidonic acid are fundamental supplements for the induction of neuronal differentiation.

Cell replacement therapy is being investigated for the treatment of neurodegenerative disorders. Adult autologous bone marrow-derived mesenchymal stem cells (MSCs) have been induced to differentiate into neuron-like cells harboring a variety of neuronal markers and transcription factors. Neural tissue characteristically contains high proportions of docosahexaenoic acid (DHA) and arachidonic acid (AA). In this study, evaluation of the fatty acid profile of differentiated neuron-like cells revealed a very low level of DHA, similar to that in MSCs but different from typical neurons. Supplementation of the medium with DHA alone resulted in increased levels of DHA but concomitant low levels of AA. However, supplementation with both DHA and AA yielded a fatty acid profile resembling that of neural tissue. It also resulted in enhanced outgrowth of neurite-like processes, hallmarks of neuronal differentiation. These findings demonstrate the essentiality of DHA and AA supplementation in the process of induced neuronal differentiation and have important implications for the development of cell replacement strategies of neural repair.

Some mothers feel their children's autism did not fully express itself until after they quit breast feeding
I wouldn't be here today, with these outlandish thoughts, but for a woman who is doing  quite an interesting series on autism and evolutionary psychiatry in a  Psychology Today blog.  Her name is Dr. Emily Deans. This is her blog

My son nursed until he was over 3, and only stopped then because I was so ill during my second pregnancy. He was diagnosed as autistic at 2 1/2, but by that time was already in every therapy known - now we just had a label. He never had formula. Just my anecdata. He also never regressed - just didn't hit milestones on time.

I do believe in breastfeeding and I did do all I could to avoid any use of formula with our kids (which meant conflict with nurses in neonatal care depts, even though they say they fully support breastfeeding), but it really does surprise me that studies about autism and breastfeeding are being reported, because surely if there was any link between the two, it would have been discovered by researchers a long time ago.

Well, I think it was a poor choice for me, as I looked at it longer. The head researcher was hardly prolific. But the study showed a lack of AA and DHA led to more troubles, which was interesting. Not so much what was in the formulas as what was lacking.

Lili, I used to go through Pub-Med articles daily, and it was profoundly confusing...but you began to see patterns. The same research "possibilities" come up again 20 years later, at times. Pub-Med went from less than 6,000 studies brought up by entering autism in the search parameter, in a period of about 30 years; to 17,000, in 11 years further research, from 1999 to now. (500 of them were autism + vaccine, just out of my own curiosity) Edision was supposed to have said, before he came up with the carbon thread for the light bulb, that he had found 10,000 things that didn't work. That's where I feel we are in autism research. We know 10,000 things that DON'T cause autism, and about 10 that do.
