Clinic Notes: Different Strains of Autism

In previous blogs I have discussed that obvious variability that exist in the behavior of the children with an autism diagnosis who come to our clinic. The Autism Spectrum ranges from children at one end who are low functioning to children at the other end who are high functioning children with autism and Asperger’s. It has never been clear if we are dealing with one disorder with varies in its severity or multiple disorders. A recent study form the University of California Davis MIND Institute sheds some light on this. In a study that started in 2006, brain growth, exposure to environmental variables, and genetic factors were examined. The 350 children in the study ranged in age from 2 to 31/2. Two sub types of autism were identified. A group of boys with enlarged brains developed normally until 18 months of age and then regressed into an autism diagnosis. Another group did not regress but showed sighs of autism early and had compromised immune systems. The investigators theorized that other subtypes would emerge in future studies. Of course identifying groups early would allow clinicians, such as myself, to individualize treatment plans.

Clinic Notes: Brain Imaging and Autism

There is no biological marker for diagnosing autism as there is for other chronic disorders. This makes research more difficult because we are not sure if our “autism group” is “contaminated” by children with other neurological disorders. Treatment is not hampered so much because these kids need treatment no matter the diagnosis and at this point treatment is pretty much the same for different neurological disorders—treat the symptoms. Researchers at Stanford are using a new Mri technology called called "multivariate searchlight classification." In this method the brain is divided into a three-dimensional grid, and each cube of the brain is examined for its volume of gray matter. Hopefully, this procedure will allow a diagnostically useful comparison between normally developing children and children with autism. Of course, the cost of diagnosis will be phenomenal.

Clinic Notes: Marriage Patterns and Autism

I see thirty or forty children diagnosed with autism in my clinic each week. The children are a good sample of the spectrum ranging from low functioning non-verbal to high functioning very verbal. The children at the high end of the spectrum are usually diagnosed with Asperger’s, a diagnosis that will not appear in the next DSM because it has been voted out. Hmm. These children with Asperger’s—excuse me—High Functioning Autism are very interesting—remarkable talents in tech areas, but not up to par in conversation and social skills. It is clear that more females are showing up in this category over the last several decades. This can be seen in the number of female college graduates in math, science, and engineering. Well, what would happen if the male High Functioning Autism met a female with High Functioning Autism. Perhaps love and marriage and a meshing of genes that would produce offspring that could account for the growing number of children diagnosed with autism over the last decade according to well known autism researcher Simon Barron-Cohen of the Autism Research Center at the University of Cambridge. An interesting hypothesis that needs data.

Clinic Notes: Something Nice

Okay I know that I usually blog about clinical and research issues concerning kids on the Spectrum, but this was just too nice to pass up. The Theater Development Fund has said that it will present “The Lion King “in an autism friendly presentation on Broadway. The usual visual and auditory stimuli that would be too much for a child with autism will be toned down and a guide for families will be sent out prior to the performance so the child will know what to expect. This will be the first Broadway show in history to play to present a special performance for children with autism. The October 2 matinee tickets will be reduced for the autism audience.

Clinic Notes: Who Should Be Licensed to Do ABA?

ABA has established itself as the treatment of choice for autism and with the rates of autism becoming epidemic pressure is on private insurance companies to pay providers for ABA. Virginia and California have passed laws to require insurance companies to pay, but the question of licensure is standing in the way. Many Psychologists who are licensed as health care providers by the state are providing behavior therapy and ABA are getting reimbursed. Board Certified Behavior Analysts (BCBA) are sometimes reimbursed by insurance companies, but they are not licensed by state health boards. Their program is a certificate program administered by their organization. Some “providers” of ABA are self-taught perhaps attending a workshop or two and are not reimbursed by insurance companies. So what should a parent do? On my website, www.ABA4Autism.com, I tell caregivers that the ABA provider for their child should at least be a BCBA. It will be interesting to see how this plays out.

Clinic Notes: The Genetics of Autism

Most of us who have been treating autism for a long time have accepted that autism is a genetic disorder. When parents, who have a child with autism, inquire about having another child, we often recite the concordance rates for them. In other words, what are the odds of having another child with autism? But I have always wondered if autism is a genetic disorder, why the sudden rise that is now epidemic. What changed all of a sudden genetically to cause the epidemic? It is unlikely that people with the autism gene(s) started mating together all at once. Something more than genetics have to be involved to account for the dramatic in autism.
In a recent study, the genetics of autism has been turned upside down. Twins were identified in the California Department of Developmental Services database who had an autism diagnosis. Of these 192 pairs of twins, which had at least one twin diagnosed with autism, the study found a concordance rate of 77% for identical twins and 31 % for fraternal. These figures are in similar to previous studies. But when these results were analyzed by a computer model that looked at the role of genetic and environmental factors the story changed. Now genes accounted for 38% of the risk factors and environmental 58%. Of course the study has been criticized.

Clinic Notes: A Biological Marker for Autism?

One big problem in conducting studies on the causes of autism is reliable diagnosis. There are no biological markers of autism so autism is inferred from the child's behavior. The problem arises then that there such obvious variably from one child with autism to another that a "spectrum" is required to "explain" this variability. So is autism one disorder or many? Obviously, this is a fundamental question that must be answered before much progress can be made in discovering the cause of autism and developing more effective therapies. A study at the University of California at San Diego found differences in functional magnetic resonance image (fMRI) scans of children diagnosed behaviorally with autism and normal controls. The fMRI's, taken while the children were sleeping, found that the two hemispheres of the brains of the children with autism were not "syncing."
Well, if this is replicated in other studies it will certainly advance our understanding. The only downside I see is that research will then be done in large universities with large grants. The cost for a fMRI and a MRI suite can run $500,000.

Clinic Notes: Antidepressants and Autism

According to a California study, mothers who use selective serotonin reuptake inhibitors (SSRI's), a common medication for depression, during pregnancy have a higher rate of children with autism. The net effect of these drugs is to increase the amount of serotonin in neurons in the brain that use serotonin as their neural transmitter. There are studies that indicate that children with autism have higher levels of serotonin in their circulatory systems. Sounds good. But there are also studies that show that children with autism have lower levels of serotonin and often children with autism are given SSRI's to increase serotonin. Confused? Me too. Because I have seen children with autism in my clinic improve when they are given SSRI's. I do not know how to explain this. But I do know that in this study and others serotonin levels are measured peripherally in the blood usually. No one has demonstrated that peripheral measures of serotonin correspond to central levels in the brain. I am getting to the point that I want to see a study that finds something that doesn't cause autism.

Clinic Notes: iPad Apps for Children with Autism Redux

At the Children's Treatment Center I see 40 plus kids per week. Most of these children, 89-90%, have autism or some related disorder. The age range is 18 months to 12 years of age and ABA, behavior management; touch screen computer drills are the therapies we have employed. But, as I mentioned in a previous blog, the iPad has beena game changer. All children, but especially children on the spectrum, are drawn to the iPad and work better on the apps that they do live or with the touch screen computer. We just put out DDT Sight Words app in the store after testing it in our clinic for weeks. Just like DTT Colors, DTT Shapes, DTT, Letters, and DTT Numbers, the kids learned much quicker, stayed on task without being prompted, (most did not want to take a play break). If I had a wish for children with autism it would be their very own iPad loaded with apps--ours--amd the many other great apps that are out there. If you are a parent, teacher, or therapists check out this amazing technology. If you have an iPad and would like recommendations for apps let me know.

Clinic Notes: Gary James' App Party for Autism

As I've mentioned in previous blogs, Apple's iPad is a wonderful tool for children with autism. The children in our clinic have what appears an almost Zen like relationship with the iPad. They calmly work on drills on the iPad like Discrete Trial Training (DTT) with greater ease and prompting than they would with flashcards. The only downside is the costs of the iPad and the apps. This past weekend, Gary James who tests and reviews apps for children with autism on his website A4cwsn, helped out by throwing an app party. iPads were give away and leading app developers either discounted or gave away free apps. To help out, Dr. Gary Brown's Autism Apps gave away 3,100 FREE copies of the Autism/DTT Shapes app and discounted our other apps. If you are interested in learning about apps for children with autism visit A4cwsn. And while you are there thank Gary James for throwing a great app party!

Clinic Notes: Developmental Disabilities in Children Are Increasing

According to a recent article in Time Magazine by Meredith Melnick, developmental disorders in children are rising. She draws on a recent study in the journal Pediatrics which found that 15% of children in the U.S. were diagnosed with a developmental disability in 2006-2008 compared to 12.8% in 1997-1999. Autism and ADHD are the disorders showing the biggest increases with autism rates 4 time greater and ADHD going up 33%. The rates in male children were twice that of females. Children from low-income families had higher rates of developmental disabilities. According to the study authors, more preterm births, older parents, less stigma, better screening, more awareness among parents and child-care professionals, are possible explanations. Their study was based on CDC surveys.

Clinic Notes: More Links to Autism Reported

This week two studies found links to an increased risk of having a child with autism. A study at the University of California at Davis found mothers who had fever during pregnancy and a difficult labor were more likely to have a child with autism.
A second study also from the University of California at Davis found that women who were obese before becoming pregnant, or suffered from hypertension, or diabetes were more likely to have children with autism. Some of these correlations were large--mothers were as much as twice as likely to have a child with autism if these factors were present. Well, anybody who keeps up with the research into the causes of autism is seeing a steadily increasing list. I am almost to the point of asking what does not cause autism. Forty years ago when I was a graduate student in a medical psychology program the research on cancer was very similar. It seemed that everyday a new study came out reporting an association between a variable and cancer. Often the follow up research was not supportive, but we still do not know exactly what causes cancer. Fortunately, we understand enough about cancer to develop effective therapies. And it will be the same with autism.

Clinic Notes: Autism Rates Are Up Again

What would a recent study on the rates of autism find? Well, if you guessed another increase you would be correct. Autism rates in South Korea are reported at 1 in 38 children. The sample was large 55,000 ages 7-12. That compares to 1 in 110 in the United States. While most studies, including the one in the US, looked at children in special ed programs, the one in South Korea looked at the prevalence of autism in the entire population.

Clinic Notes: Cost of ABA

As most parents of children with autism know, Applied Behavior Analysis (ABA) as a treatment for children with autism was pioneered 25 or so years ago by Ivar Lovaas. This was before autism was epidemic and somewhat of a novelty diagnosis. Many parents and some therapist say that ABA cures autism and will spend anything to see that their child get ABA. ABA does not cure autism. Lovaas's studies did not show that ABA cured autism, but that children with 40 hours of ABA weekly were more likely to be mainstreamed. Most children with autism will need speech and occupational therapy for fine motor problems in addition to ABA. Some families are spending $100,000 yearly for ABA. Sometimes insurance companies will pay for ABA and even have a billing code for ABA. But then again in some states the same insurance will deny payment saying that ABA is experimental. Now I am a psychologist in the ABA business and live in a rural community. I don't know of anyone spending six figures on ABA. Licensed Psychologists and Board Certified Behavior Analyst (BCBA's) are qualified providers of ABA. Someone who has been to a workshop on ABA is not. Spend your money wisely.

Clinic Notes: The Business of Autism

I see 40 children each week at the Children's Treatment Center. In addition, I blog weekly, trying to keep everyone informed about the autism war in the trenches, process orders and answer emails at my website www.aba4autism.com, trying to provide materials worldwide for parents who cannot afford professional services. I also design apps for the iPad, iPhone, and iPod touch for children with autism who are hooked on these devices. Now, last month and this I have a new product in my autism world--putting on a 5k run and 1 mile fun walk with the proceeds going to Autism Speaks. Much of my research into the causes of autism is on the back burner for now. Maybe after the 5K I will have time to get back into it. Hmm--if someone discovered a cure for autism I wonder how I'd spend the rest of my life. Smiling.

Clinic Notes: "Wretches and Jabberers"

Tracy Thresher, who is nonverbal because of autism, and friend Larry Bissonnette call themselves "wretches" and people who can speak they call "jabbers." Their message, the subject of a new documentary being released in 40 cities, is simple. They are intelligent, but intelligent in a different way--a way that requires people to look beyond the "wacky, goofy behavior." Disability does not equal dumb is the message they try to spread as the travel to Sri Lanka, Japan and Finland.

Clinic Notes: Virtual Conversations and Autism

My clinic experience with autism and technology, such as computers and iPads, and reports of children with autism interacting with robots, has led me to believe that effective treatment of autism has to involve technology. So I was glad to see a report this week which found that adults with autism improved when they interacted with a virtual partner. The study was reported in "Cyberpsychology, Behavior, and Social Networking. The adults with autism in the study were high functioning and were given onscreen dialog options for their conversations with their virtual partner. They were able to initiate and maintain a conversation on a variety of topics. Perhaps one day these can be implanted and cue the child to converse appropriately in different social situations.

Clinic Notes: iPad DTT Apps for the Child with Autism

Our third iPad DTT app for teaching letters to the child with autism is now in the iTunes store. Our Facebook page has free redeem codes. I have been treating autism for a long time and I am amazed at how well the iPad works with children with autism. Contact me at www.aba4autism.com and I will send you suggestions for apps from other developers that we use in our clinic.
