Clinic Notes: Hyperbaric Chambers and Autism

"Treating" autism is big business. Anecdotal reports have reported that children with autism have shown remarkable gains following exposure to increased oxygen in hyperbaric chambers. Supposedly, the increased oxygen increases blood flow thereby decreases inflammation, which changes the brain chemistry that causes autism. Of course, this is all hypothetical and no double blind randomized studies have been done until now. Researchers at Center for Autism and Related Disorders found no significant effect following hyperbaric therapy. I'm not surprised at the results. What I wonder about is how all this got started? Hyperbaric chambers have a long history in medicine and while there are legitimate uses there are also many times that hyperbaric chambers are used with scant data supporting their use. Furthermore, many of the studies are funded by the manufacturers of the hyperbaric chambers. (See the New York Times review by Jane E.

Clinic Notes: Treating Autism in a Rural Area While Waiting for Healthcare Reform

Many children with autism have ADHD like behavior and do well on stimulant drugs. Most pediatricians and family practice physicians have no problem prescribing these medications. But I am a psychologist practicing in a rural area and often see children who have no health insurance or their health insurance won't pay for the treatment of autism. So I'm supposed to treat a child with autism who has no access to a physician, and no way to pay for medication. Well, people in a rural area learn to get by with what they have available and I guess that includes me. Caffeine contains methylxanthine, which is a mild stimulate similar to what is found in ADHD stimulate drugs. (Stimulate drugs often have a paradoxical effect on ADHD behavior--decreasing it rather than increasing it.) Coffee can sometimes be used as a replacement ADHD drug sometimes in children as well as "energy drinks" like Red Bull. The problem is dosage. A child would have to drink a lot of coffee to get the equivalent stimulant effect of a large dose of an ADHD drug. But when only a small dosage in needed caffeine can work.

Clinic Notes: So Long Asperger's. I Hardly Got to Know You.

In 1944 Viennese physician Hans Asperger described a sample of children with high functioning autism who had normal intelligence and language, but were socially awkward and obsessed on various topics. In 1994 the term Asperger's Syndrome was added to the Diagnostic and Statistical Manual of Mental Disorders (DSM-IV. With the autism epidemic more and more children with Asperger's are being diagnosed and treated effectively. Now I have learned that in the next edition of the Diagnostic and Statistical Manual of Mental Disorders (D.S.M.-V) the "experts" are proposing that the term Asperger's Syndrome be eliminated and simply called Autism Spectrum Disorder. Well what could go wrong there? Asperger's is just now being accepted by the public, and more importantly kids who are diagnosed with Asperger's and call themselves Aspies. Furthermore, there are over 200 thousand websites devoted to Asperger's (many maintained by Aspies) and countless books and articles. Are these going to become obsolete by the vote of a committee?

Clinic Notes: What Has More Research on Autism Told Us?

A decade or so back, when it became apparent that we were in the midst of an "autism epidemic" the call was repeatedly made for more research into the potential causes of autism and effective treatment options. Now so much autism research is being done I have trouble keeping up with it. Well, I think it is time to ask the question, "What have we learned?" from all of the research. Of course trying to answer this question will generate a lot of arguments--some very volatile, but I have no agenda and will try to answer these questions as I see them.
I think the evidence is compelling that in most cases of autism mercury is not involved. When mercury was taken out of vaccines rates did not drop and in countries where vaccinations are not mandatory the rates of autism are the same in vaccinated and non-vaccinated groups.
Secondly, I don't think in most cases of autism gastrointestinal disorders are a factor. Most of the children with autism who have come to my clinic over the years do not have gastrointestinal problems. A recent study at the Mayo Clinic confirmed this. Gastrointestinal disorders do not occur at a higher rate in children with autism.
Chelation therapy, gluten free diets, and hyperbaric chambers do not cure or even improve the lives of children with autism. All evidence to the contrary is anecdotal and has not been confirmed in double-blind studies. I realize this will not set easy with many people. But I am in the trenches, treating autism daily and I just don't see progress in children who have had these therapies and I think the research is as conclusive as research can be. Research should continue, but it is time to move on to areas of research that have more potential.

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.

Clinic Notes: There's an App for That

Applied Behavior Analysis (ABA) is the most effective treatment for autism. Unfortunately, well-trained ABA therapists are expensive and hard to find. On my website (www.aba4autism.com) I offer an online ABA course for caregivers as well as ABA eBooks, ABA Case Histories, and individual ABA programs. Many parents and other caregivers who have not been able to find and/or pay for an ABA therapist have told me how helpful my website has been for their child with autism. I was watching an iPhone commercial the other day that was talking about all of the apps that could downloaded to the iPhone--apps for everything imaginable and I got to thinking. Why not iPhone apps for ABA? I'm working on it.

Clinic Notes: Autism in Adults

As I have mentioned in previous blogs the incidence of autism is rising. This is well documented by stats put out by the CDC and I see many more children in my clinic now with an autism diagnosis then I did in the past. In the last decade or so many researchers label the rise as an explosion. Well autism is a lifelong disorder and one question that has not been answered is where are the adults with autism now? And how are they functioning? Are we going to have to have massive programs to aid adults with autism when the children we are seeing now grow up? A recent study in England attempts to answer some of these questions. England's National Health Service conducted surveys on the prevalence of psychiatric disorders in adults. In regard to autism, the finding of interest was how many adults with autism there were. Most were unmarried males and the frequency was 1 in 100 adults, which was in line with the stats reported for children. Furthermore, the study did not look at adults with autism living in institutions, which would have raised the incidence of adults with autism even higher. This was a small study, but if it is replicated with a larger sample it is hard to argue that an autism epidemic is taking place.
