Rare Form of Autism Could Be Curable With Protein Supplements 163

ananyo writes "A rare, hereditary form of autism has been found — and it may be treatable with protein supplements. Genome sequencing of six children with autism has revealed mutations in a gene that stops several essential amino acids being depleted. Mice lacking this gene developed neurological problems related to autism that were reversed by dietary changes (abstract). According to Joseph Gleeson, a child neurologist at the University of California, San Diego, who led the study, 'This might represent the first treatable form of autism.' It is possible that some other forms of autism may also be linked to uncommon metabolic disorders — and so treatable through dietary changes, according to the scientists quoted in the piece."

        If you RTFA, you'll see that all of the children they identified had those characteristics because it made them easier to identify. It doesn't say only children of middle eastern descent whose parents are 1st cousins can be treated with supplementation. It says the children identified by those traits had a form of autism that is also linked with the inability to transport those amino acids. Because their bodies are not able to process those amino acids it is theorized that supplementation may assist treatment. But more than anything, if you were a parent or caregiver of an autistic child then why wouldn't you try protein/BCAA supplements? These supplements are widely studied and concerned safe as far as I have ever read. They are readily available, just go to your local GNC. Or any supplement website.

          I guess you missed: The researchers found that the supplements restore the children's blood levels of amino acids to normal. As for their autism symptoms, Gleeson says, the “patients did not get any worse and their parents say they got better, but it’s anecdotal”. Doesn't sound promising. Since normal brain development is a process that starts in utero, these amino acids are something that might require treatment to start immediately after birth to have any effect at all.

      It sounds from those two sources like many cases of autism could be prevented by higher vitamin D levels of pregnant women and better diet, but in the first few years of life after birth, some aspects of autism can be reversed with vitamin D supplements and good diet. How far and for how many kids is still an open question.

So what we have in terms of "autistic behavior" in animals are things along the lines of "does the 'autistic' mouse sniff the other mouse le

    We already knew about some forms of autism where a genetic disposition causes the lack of dipeptyl-peptidase IV, the enzyme responsible for breaking proline bonds during digestion. Proline needs a very special enzyme because the amine is tertiary, while it is secondary on other amino acids.

    Gluten and casein contain sequences with a lot of proline, and this class of autists never digest them completely. They are left with short proline-rich peptides known as gliadomorphine and caseomorphine. As the name suggests, theses peptides are able to bind morphine receptors in the brain. And for this class of autism, symptoms disapear with a diet without casein and gluten.

    And now we have autists with another genetic disposition related to protein digestion, this time with valine, leucine and isoleucine not being digested, and missing in the brain because they are essential amino acids. I wonder if we are going to discover more autism forms as being protein digestion issues

    I have a metaphorical way of making sense of autistic behaviors. Let's say the brain has some kind of sensory input buffer. Defects in that buffer might lead the brain to be overstimulated with sensory input and become preoccupied with them. The other thing the buffer might do...and this is where it gets more metaphorical and maybe less factual...is serve as a feedback path for brain-generated inputs, to sort of test things. Like when someone says "Imagine what it feels like when..." or even when you just think about real experiences you had. I think of dreams as maybe working like that too: brain generated inputs get cycled back through the buffer to serve as virtual experiences for...whatever dreams are for. That way of thinking about it leads to a way of understanding stimming behaviours: they can be thought of as dream-related movement that we don't do during sleep dreams because of sleep paralysis.

    This is great, but it's not the first dietary link and metabolic disorder with a connection to autism. Phenylketonurics have diminished or zero ability to process phenylalanine, an essential amino acid. The build up of that material in the body causes multiple deleterious effects, including autism. People with PKU cut their intake of phenylalanine and they don't suffer the effects they would have. That's been known for decades.

    Being autistic, there are some limitations in my world from the viewpoint of other people. In my view, they are limited more than I am. I can understand what people are talking about even when I can't directly relate to it through personal experience or don't give the emotional response that others might give. I, however, can see past what they're talking about in ways that they cannot because of the limitations that they have in having information filtered out that I still receive. Yes, it can be an overload at times and there are situations that I don't deal well in (like crowded rooms, loud environments, or very bright environments), but I find that my particular form of autism is a huge benefit to me. I can conceptualize things that most people can't imagine exist. I can find solutions to problems from disparate sources that other people don't see as relevant to each other.

      Because you aren't the presentation that such a cure would be appropriate for. But since autism is a spectrum disorder, and still a fairly general diagnosis at that, your specific presentation doesn't generalize to the affected population. Heck, we don't even define that population very concisely yet.

      I'm glad you see your condition as a positive one, and I sincerely hope that those around you also view your condition positively (and I use the term "condition" here with some hesitation, only because I don't know a better term and truly don't mean to be pejorative). But I know kids with the diagnosis who I'm not sure share your feeling---if they are even that aware. And their caregivers are greatly affected by their condition as well. Even something that just significantly improves their condition, without curing it, would improve everyone's lives immensely.

      And at the rate of increase of Autism-related diagnoses without anything resembling a cure on the horizon, we don't have to continue much farther before society as a whole must plan for accommodations. Many children with the diagnosis will need intensive, life-long supervision. Think Alzheimers, but over many, many more years.

    My socially awkward and geeky personality led to pretty much every pre-med I met in college trying to diagnose me with autism. One of the diagnosis criteria that I remember them mentioning was food acceptance or preference issues (eating the same thing all the time, refusing to try new things, etc.). It's since been removed from the diagnostic criteria (it's not nearly selective enough), but it still occurs in a significant majority of cases. I'm curious if there could be a link here. The mice in the study were treated with a diet high in branched chain amino acids. According to livestrong, those foods are... well, I'd generally call those "kids food": red meat, chicken, nuts and cheese. I wonder if food acceptance issues in autism have a biological underpinning and kids are, essentially, trying to self-medicate with chicken fingers.
