Clinical Notes: Autism in the News

There's no doubt about it. Autism is in the news and everyone has questions whether they are directly affected by autism or not. I was waiting to see a doctor at Vanderbilt several days ago. My wife started a conversation with a woman beside her and eventually the small talk got around to what I did. When my wife said that I was a psychologist who worked with children with autism a hush fell on the room. Everyone in the room looked at me and I couldn't hide behind my magazine. Then the questions started. First, from parents and grandparents, and teachers who had been directly affected by autism, and then by the curious who had read some article in the popular press. There were specific questions about specific children and then more general questions: Is one out of every 150 children affected? Do vaccines cause it? How can it be cured? I answered all of the questions as best I could and everyone was very appreciative. And then I was called back to the doctor's ofice. I was thinking about the questions I wanted to ask the doctor about my own health when he walked in. After a brief introduction the first question out of the doctor's mouth was, "what happens to children with autism when they grow up?" Autism is in the news.

Clinic Notes: Special Education and Autism Stats

According to some reports we are in the midst of an autism epidemic with one out of every 150 children diagnosed. At the same time the number of children diagnosed with learning disabilities or mental retardation is declining. Now we hear that for the first time in history the number of children in Special Education declined by 2.4%. (http://tinyurl.com/yuh59z) Furthermore, the number of children age 3-5 entering public education with speech/language impairments dropped 5%.
So what's happening? Are the speech/language impaired kids, which make up half of the kids with disabilities, now being diagnosed with autism and going into private autism schools where they can get more ABA? I'm confused

Clinic Notes: Thomas the Train, Bob the Builder, and ABA

There is some literature that suggests that children do not make eye contact because they perceive eye contact with another person as threatening. In fact some studies fine that if children with eye contact do look at faces they only see the mouth and nose. Interestingly, the face on Thomas the train and the construction equipment on Bob the Builder attract many children with autism. A recent study in Great Britain (http://news.bbc.co.uk/1/hi/health/6241733.stm) used vehicles with human faces to try and teach children with autism to overcome their fear of looking at faces. In my clinic I have been using Thomas the Train and Bob the Builder videos to teach children with autism how to label emotions with some success and plan a controlled study in the near future.

Clinic Notes: ABA and the Neurosciences

Most ABA therapists have little background in the neurosciences. Unfortunately, this often results in a "one size fits all" approach to ABA. In our clinic some children with neurological impairment resulting in low muscle tone get fatigued very quickly doing Discrete Trial Training (DTT). With these children we slow down, have longer intervals between trials and give frequent breaks. I've seen ABA therapist push these kids to the point that they break down and profit little from ABA. Other kids with ADHD types of behavior may need shorter intervals between trials and less frequent breaks to keep them on tasks. In my few view, at least one course in basic neuroscience.

Clinic Notes: The Autism Genome Project

What is being hailed as the largest genome scan ever has come up with two genetic abnormalities in families with at least two member diagnosed with autism. The gene neurexin 1 located on chromosome 2, which is know to be associated with the neurotransmitter glutamate, is one suspect as is several locations on chromosome 11. As many as 30 other genes are also suspects in the disorder and are under investigation. Research in genetics is an important part of the puzzle and these are interesting findings. But I am still puzzled. When you read genetic studies somewhere in the write up autism is referred to as a highly inheritable disorder. However, the concordance rate for identical twins is only 60% and drops to 4-8% for fraternal twins and non-siblings. Without doubt something else is involved in the etiology of autism.

Clinic Notes: Autism Myths

The sign hanging in front of my clinic building says, "The Children's' Treatment Center." And in small letters under the name, "For Autism or other Childhood Developmental Disorders." I am located in an old historic part of town where buildings build in the late 1800's have been restored; surrounded by lawyers, CPA's, and upscale retail stores. I am always asked the question by people aroung me, "What is autism?" That is a difficult question to answer and difficult for people to understand. The movie "Rain man" is the only exposure most people have had to autism until recently when autism has been in the popular media.
Part of the problem in answering this question for the general public is the lack of consensus for those of us who work in the field. Simple questions such as "Is autism increasing in children," cannot be answered to everyone's satisfaction. We are not even close to answering the question, "What causes autism."
There are so many controversies that "experts" at the 2006 annual meeting of the American Association for the Advancement of Science tried to separate "fact" from myth. Unfortunately, the experts could only argue about the interpretation of the limited amount of data, often contradictory, that we do have.

Clinic Notes: The New Autism Numbers

In a recent study, CDC reports that 1 in every 150 school age children are affected by autism. When I started practicing 35 years ago the numbers were more like 1 in 10,000. The lower rates are reported in the South and the higher rates in North Eastern cities. Whether this difference is real or because more services are available and a diagnosis is more likely in the North Eastern cities than the South is not known. The authors of the study say that the rise in autism rates could be related to better surveillance procedures now than in the past. Personally, I don't think 1 child out of every 150 has any chronic disease, Including autism. (Diaper rash could be the exception.)

Clinic Notes: ABA, Music, and Autism

I see many children with autism in my clinic who are music savants. They have perfect pitch and can play a song on the keyboard after hearing it one time. The percentage of child with autism that have special music abilities is not know, but it is estimated that 10% of children with autism are savants.
In addition, many children with autism like music and we use it as a reinforcer in ABA programs. (Some kids with autism find music, and sounds in general aversive and cover their ears.) Neuroscientists tell us that infants are born with music preferences and even seem to enjoy music while still in the womb.
Some years back I had a 3 year-old girl come to my clinic with a diagnosis of autism. When I was taking her history her mother said she was not verbal, but she could sing. I then asked if she could follow directions. The mother said yes as long as she sang them. I then watched mother sing a direction and her daughter sang back her reply.
Tere is no music center in the brain. Pitch, loudness, and dimensions of music are in circuits of nerve cells, which are spread around in different parts of the brain. Why some children with autism have savant abilities is not even close to being understood.

Clinic Notes: ABA and the Rising Number of Children Diagnosed with Autism

In the January 31, 2007 Schafer Report (http://www.SARnet.org/), two separate articles dealt with the rising number of children diagnosed with autism. In California, 3385 new were added last year. The second article discussed the difficulty in determining whether or not the increase was real, and if it was, what was causing the increase.
Without doubt, I think there is an increase in the diagnosis and miss-diagnosis of autism. I see that almost everyday in referrals made to my clinic. But I also think there is something else going on. Autism does have a genetic link, but I'm not sure more people carrying the autism gene or genes are breeding and having more children with autism. I have no data to support that belief, but that is my belief. I think our attention needs to be directed towards the environment.
At any rate, it is getting very difficult for those of us in ABA to offer intense ABA for a child when we have so many children diagnosed with autism on our waiting list. Do I schedule one child for 10 hours of ABA a week? Or do I see ten children for one hour?
