Tummy Troubles: Studying the Relationship Between Autism and Gastrointestinal Disorders

February 6, 2012 54 comments

Guest post by neurobiologist Pat Levitt, Ph.D., of the University of Southern California’s Keck School of Medicine, in Los Angeles

Many children with autism spectrum disorders (ASD) have co-occurring medical conditions that affect their quality of life and response to therapy. One of the most common of these medical conditions is gastrointestinal (GI) disorder. Our research directly examines the relationship between the two and creates a foundation for understanding the biology and behaviors unique to children affected by both disorders. It is described, in detail, in our recent report in the journal Autism Research.

Our multi-disciplinary research group included neuroscientists, a clinical psychologist, a pediatrician and a pediatric gastroenterologist. We enrolled 121 children through Vanderbilt University, in Nashville, primarily through Vanderbilt’s autism clinic, which is part of the Autism Speaks Autism Treatment Network (ATN). These children fell into one of three groups: those with ASD and GI disorder, those with ASD only and those with GI disorder only. Their parents completed a dietary journal and questionnaires about the children’s behavior and GI symptoms. In addition, a pediatric gastroenterologist evaluated the children with GI disorders.

We found very high agreement – more than 90 percent – between parent reports of GI symptoms and the gastroenterologist’s evaluations. While the specific description of the GI condition sometimes varied between parent and physician, these findings suggest that contrary to what some people think, parents do not over-report GI conditions in their children. Also contrary to some popular thought, the children’s diet and medications did not significantly contribute to their GI distress.

Overall constipation was the most common GI diagnosis. It occurred in 85 percent of children with both autism and GI disorder and was most likely to occur in children who were younger, nonverbal and/or had significant social difficulties. In fact, we found a six-fold increase in communication disturbances in the group of children who had both ASD and GI disorder, compared to children with ASD only.

This strong association between constipation and language impairment has the support of a previous study showing a unique genetic association between children with ASD and GI disorder. As such, our findings further highlight the need for healthcare providers to be vigilant in detecting and treating GI symptoms in children on the spectrum. This is particularly important in the care of nonverbal children who can’t describe their distress. Our research also provides a strong foundation for further research on the causes and treatment of autism associated with GI disorder. We need to know more about how these co-occurring conditions affect the mental and physical health of so many children and adults.

Thanks for joining today’s “Office Hour” webchat with Drs. Dawson and Horrigan . Here is the transcript.

Please join us next month (March 1st) and every first Thursday at 3 pm Eastern. Look for the “Live Chat” tab in the left column of our Facebook page: https://www.facebook.com/autismspeaks

2:53
Hi everyone! We are just about to start!
2:56
Comment From Tyler Munoz hi.
2:56
Comment From Tinagood afternoon doctors
2:57 Hi Everyone! This is Dr. Dawson. We will be getting started in just a minute or so. We are glad you are here.
2:59 Hi – this is Dr. Horrigan – I’m here , too – thanks for attending today’s ‘office hours’
3:02 Advance question from Lisa, teacher of students with ASD: I have heard a few things…completely rumors…about how gluten-free diets affect those with autism. What are the affects, positive or negative, if any. Thanks!
3:02 Lisa: This is Dr. Horrigan. Yes, for some youngsters with autism, gluten-free diets can be helpful, but it is a minority rather than a majority that benefit, and it is usually youngsters that have a specific family history of GI problems and difficulties with food sensitivities, including more explicit problems like Celiac sprue related to gluten. It is worth having a discussion with the child’s physician about the potential utility of elimination diets (like gluten-free) if the youngster has persistent gastrointestinal problems and the family is motivated to shift (oftentimes the whole household, to assure the child’s adherence) to the specialized diet. The participants have to watch out, though, because it is relatively easy to become deficient in some essential vitamins and minerals if a rigorous elimination diet is pursued – so supplementing with essential vitamins and minerals would be important, too.
3:04
Comment From Tina My son is 12 years old and is still in pull ups, he knows when he needs to go to urinate but not to do a bowel movement. Is there anything I can do to make him more aware. We sit him on the toliet several times a day but with no luck. If you have any suggestions please let me know. Thank you
3:05 Hi Tina, There are some good books that offer strategies for teaching children with autism to use the toilet. Here is one suggestion: http://www.amazon.com/Toilet-Training-Individuals-Autism-Developmental/dp/1932565493 . We will be posting a tool kit on toileting on our website soon so keep your eyes out for that. YOu might also want to check with your behavior therapist, if you have one, who can develop a behavioral plan for teaching toileting.
3:06
Comment From CaraMy son is 6 and the dr prescribed him intuniv to help with some of his behaviors. Is this a typical drug? Do the drugs help?
3:07 Hi Cara – this is Dr. Horrigan – Intuniv (guanfacine) is becoming more popular. It is formally indicated for the treatment of ADHD, and it is often helpful in combination with stimulant medicines like Ritalin or Adderall. But it can be helpful on its own to soften difficulties with impulsivity and excesive emotional outbursts. It doesn’t work for everyone, though, and it has its own unique side effects, especially if the dose is too ambitious (e.g. sedation/sleepiness/fatigue, headache, and there is even a potential for decreased blood pressure). So it needs to be taken under a doctor’s supervision. Definitive studies in the area of autism have yet to be completed at the time of this writing, but they should be forthcoming.
3:08 Dear everyone, Many of you have had questions about the new revisions to the diagnostic criteria for autism. Below is our policy statement on this issue which describes the issues that we all are concerned about and what Autism Speaks is doing to ensure that the revision doesn’t end up excluding people from obtaining the services they need.
3:09 Autism Speaks Statement on Revisions to the DSM Definition of Autism Spectrum DisorderAutism Speaks is concerned that planned revisions to the definition of autism spectrum disorder (ASD) may restrict diagnoses in ways that may deny vital medical treatments and social services to some people on the autism spectrum. These revisions concern the 5th edition of the Diagnostic and Statistical Manual of Mental Disorders (DSM-5), scheduled for publication in spring 2013.We have voiced our concerns and will continue to directly communicate with the DSM-5 committee to ensure that the proposed revision does not discriminate against anyone living with autism. While the committee has stated that its intent is to better capture all who meet current diagnostic criteria, we have concluded that the real-life impact of the revisions has, to date, been insufficiently evaluated.Autism Speaks is committing substantial effort and resources to fund definitive research to ensure that the final definition of ASD meets the following criteria:1. Assures that all those who struggle with autism symptoms receive the treatment, services and benefits they need, without discrimination;2. Affirms that ASD can be a lifelong diagnosis, while allowing for treatment and services to change with an individual’s evolving needs;

3. Supports the importance of early ASD diagnosis and treatment as essential for helping individuals achieve their best possible outcomes and avoids creating barriers.

As the proposed diagnostic criteria are evaluated over the course of 2012, Autism Speaks will be working with leading experts in the field as well as community stakeholders to evaluate the potential impact of the DSM revision on our community and to ensure that all necessary adjustments be made to assure access to vital treatment and social support resources for all those who struggle with the symptoms of autism.

At the same time, we will actively serve as an informational resource and advocate for all members of our community, as they seek to make their needs known and understand how the evolving changes will affect them and their families.

Comment From Nancy MBI hope you can help,my daughter was diagnosed with ADD when she was about 2 now she is 20 and people keep telling me to have her checked because the way she has always been she could have a form of autism what should I be looking for ?
3:11 Dear Nancy, This is Dr. Dawson. Does your adult daughter have significant problems with social interaction, such as problems with eye contact, difficulties forming friendships, or trouble with conversational skills? Does your daughter have overly focused interests or engage in repetitive behaviors? If so, she may have an autism spectrum disorder. Having a diagnosis may open the door to services that could help. Check the following link to find resources in your area:

3:12
Comment From GuestSo, can I just ask a question anytime? Never done this before
3:12 Dear Guest at 3:02 – Yes- please just submit your question.
3:14
Comment From Tina SOur son has PPD and is 10 years old. He continues to write letters backwards and if something has a price of say $19 he says “$91″ We have asked and asked for him to be evaluated for dyslexia. Does anyone else have children with symptoms like this? Should we continue to pursue dyslexia along with the PPD or is the backwards spelling and seeing part of the PPD?
3:14 Dear Tina, A child with autism can also have dyslexia, that is, trouble with reading. It is important that you have your son evaluated by a person who has expertise with dyslexia so that you can provide treatment for his reading difficulties along with treatments for his autism.
3:15
Comment From LinneaI have a question: My son has been diagnosed with PDD-NOS and an anxiety disorder- NOS, but his OT has raised concerns about SPD as well. All the symptoms seem to overlap – how can you determine what is caused by what? Or how can a doctor tell if a child has one disorder or another (or both). We are going to a specialty clinic in about 6 months and I’m hoping to get some definitive answers.
3:16 Dear Linnea – this is Dr. Horrigan – I am assuming that SPD refers to “sensory processing disorder”, is this correct? There is a suite of specialized, hands-on tests that occupational therapists use to diagnose under- or overactivity to sensory stimulation, whether it is touch or heat/cold or sound, etc. I agree with you that it can be difficult to disentangle sensory prcessing problems from free-standing difficulties with anxiety. A lot of times it is important to determine if there is a high risk of anxiety disorders in an individual with autism based on one’s family history of anxiety, in which case, behavioral and medocation treatments (e.g. SSRIs like Zoloft/sertraline) can be really helpful, and you can get more traction from the desensitization techniques used by occupational therapists (e.g. brushing, as one example).
3:18
Comment From Loriif a childs does not show GI problems will a GFCF diet help in any way?
3:18 Hi Lori, This is Dr. Dawson. Some parents report that a GFCF diet can help even though specific GI symptoms are not present. If you decide to try a GFCF diet, be sure to have someone who doesn’t know whether or not your child is on the diet keep a record of your child’s behavior (such as your child’s teacher). This way, you can objectively determine if it is helping. Also, check with your pediatrician about monitoring your child’s nutritional intake to make sure he or she is getting the nutrients your child needs.
3:20
Comment From SandhyaHow do we for sure know that my kid has high functioning autism and Are there any tests to find out (lab tests) and how do we know which food are good and bad for them ?
3:21 Dear Sandhya, This is Dr. Dawson. The diagnosis of autism is made on the basis of behavior observations. There are no specific lab tests for autism. Once a child has been determined to have autism, based on behavior, your doctor would want to order specific genetic tests to determine if there is a genetic cause. Other lab tests are sometimes ordered. If you have concerns about your child’s eating, you should talk to your child’s pediatrician. Autism is often associated with difficulties in eating, such as food allergies and food sensitivities.
3:22
Comment From GuestMy son won’t eat for days or weeks at a time. We are waiting for our appt at CHOP’s feeding clinic, and I keep hearing how awful or intense it is. What can I expect? Will he have to go inpatient?
3:24 Dear Guest – this is Dr. Horrigan – that must be very stressful, having such unpredictably as to when your son will/won’t eat. It would be good to know exactly where your son is on the CDC growth charts, and what sort of medical workup has ben done so far. . I think at CHOP they will start off with straightforward things like a flat plate x-ray of your son’s abdomen (it’s painless) and they will obtain a comprehensive dietary history. They will also look at what runs in the family (e.g. things like Celiac sprue, irritable bowel, etc.). If there is specific evidence for a malabsorbtion syndrome, they will do more intensive things. They may also have to look more specifically at endocrine issues which usually means some blood tests (the blood volume they draw isn’t too bad, and they shoudl use topical anethetics or numbing meds) and they may also want to do an MRI (e.g of your son’s head), which is challenging because it can be loud and long and he will have to keep still – often means sedation has to be used.
3:25
Comment From EnidCan you recommend me a good book on autism? This topic is new for me and I don’t know anything. I will love to learn more. My son is 3 years old. I will like to help him and understand him. I am thinking to buy these two books: 1001 Great Ideas for Teaching and Raising Children with Autism or Asperger’s, / Ten Things Every Child with Autism Wishes You Knew. Please help me.
3:25 Dear Enid, This is Dr. Dawson. The Autism Speaks website is full of information and resources, including a list of books on different topics. Look under “What is Autism” and “Family Services” for information. I really like Lynn Koegal’s book – Overcoming Autism.
3:27 Dear everyone, I notice that there are many questions about GI problems, constipation, toileting, and eating. On our next webchat (next month), we will have a gasteroenterologist with expertise in autism on this webchat so we can provide more detailed information. Autism is commonly associated with Gi problems and it is important that these be addressed by a gasteroenterologist. These problems can interfere with a child’s ability to learn and behave well.
3:29
Comment From Guesti have an 8 yr old with bed wetting as well
3:30 Dear Guest – this is Dr. Horrigan – I may have missed the first part of the question or the discussion thread about bed-wetting. But what comes to mind is that there are basic behavioral manuevers that can be helpful (e.g. humane versions of fluid restriction before bed, and also humane use of bell and pad/alarm techniques – the latter can be tricky). It is also important to make sure tht he is not constipated as this can cause overflow incontinence even at night. There are some meds that can precipitate enuresis (e.g I am thinking of unpredictable responses to meds given at nightime like risperidone and some of the SSRIs), so you have to make sure that you are not dealing with a medicine side efect. That said, it is possible that other meds like DDAVP pills (0.2 to 0.4 mg) or low-dose imipramine (25 mg or less) can be really helpful if the bed-wetting is really causing a lot of distress.
3:31
Comment From JillHello, My son just got diagnosed with Autism, he is 4 years old. One of our biggest challenges right now is his sleep pattern. Lately he will stay till 10 or 11pm, wide awake, and then sleep for a few hour incriments, he wont sleep in his bed, unless we put him there after he falls asleep, and even then it is only for a few hours. Any helpful hints ? It is getting really difficult on us, and we have 2 other children that are in elementary school…who need their sleep.
3:31 Dear Jill, This is Dr. Dawson. Sleep problems are very common in children with autism. On February 14th, Autism Speaks will be releasing a new tool kit for families and providers on how to address sleep problems in children with autism. Check back on our website on the 14th. I think you will find it very helpful. We are funding many studies on sleep, including treatment studies.
3:34
Comment From JoshuaHello, Our son is four years old and his primary symptom of autism is his use of delayed echolalia. Although it seems to be very well documented that this is a major symptom of both autism and tourettes, there seems to be little research regarding what helps “cure” it. Everything just says, “it decreases as functional language increases.” Do you have any helpful information related to delayed echolalia and the treatment?
3:35 Dear Joshua, This is Dr. Dawson. It is useful to understand what is the function of the delayed echolalia for your son. Is it a way of communicating his needs and wants? If so, then modeling a simple phase for him to use instead of the echoed response (ideally, that uses part of his response) and having him repeat the appropriate phase before getting what he wants may help. Is it a repetitive behavior? Distraction and involvement in other activities could be useful. Is it a sign of anxiety? Then, addressing the source of anxiety can help. It is true that echolalia does tend to naturally decrease as functional language develops.
3:36
Comment From LoriOur son is 8 very HIgh functioning but is having a hard time focusing at school what could help with this. I hate the thought of meds.
3:37
Comment From Guestlisa pa i have a 8 yr old with autism and a 15 yr old with tubersclerosis and i belive he is on the spectrum but drs only seem to stop at the tsc i i was wondering how to approach treatment of his autism with tsc
3:38 Dear Lisa, This is Dr. Dawson. Many children with tubersclerosis also have autism and it is important that both diagnoses are made. This will allow your child to receive specific interventions to address the symptoms of autism (e.g. social impairments) that not all children with TSC have.
3:38 Dear Lori – this is Dr. Horrigan – does your son have an IEP or 504 plan that includes the classic accomodations for indivduals with ADHD? I am thinking about the use of a carrel, as needed, and the proactive use of verbal cues as transitions occur in the classroom, as well as electronic desktop cueing devices triggered by the teacher or assistnat. In terms of meds, I know how you feel, in terms of your wariness, although sometimes you can get great benefit from the judiciosus and thoughtful use of stimulants, with the knowledge that each person has unique responses to each of the stimulant formuations/preprations (e.g. it is not just about Adderall or just about Ritalin, there are a whole range of choices), and this is important because soemtimes a youngster with HFA can get a very significant effect/benefit from a low dose of a carefully chosen med
3:40 Advance question from Pamela: My question is…is there any link between taking antidepressants while pregnant (2nd & 3rd trimester)(SSRI) and autism in the newborn child?
3:41 Hi Pamela. This is Dr. Dawson. We have written previously on this topic, and I refer you to that blog (link below). This is a question you should discuss with your physician because each woman’s situation is different in terms of weighing the risk and benefits.

3:41
Comment From KathleenMy son is 3 years old. He did not start speaking until he was 2 and 1/2 with the aid of Speech and Occupational therapists and a special education teacher. I have been told he has SID (sensory integration dysfunction) Some sites say SID is a disorder and some say it is a symptom of autism. I have concerns that he is on the spectrum at some level because of some of his behaviors but only 1 of his teachers agree. the other 2 and his pediatrician say i am “overreacting”. Who is right? Who should I listen to?
3:42 Dear Kathleen, Some children with autism have sensory integration dysfunction but not all do. Children with autism tend to have more significant difficulties in social interaction (e.g. eye contact, forming friendships, interactive play) and also have repetitive behaviors. You should have your son evaluated by a doctor with expertise in autism to better understand his diagnosis. You can check on this link for resources in your area:
3:42 http://www.autismspeaks.org/family-services/resource-library
3:45 Advance question from Andrew: Where can we find career guidance in the autism research field?
I’m a 24 year old patient advocate. After spending 3 months on a Nation Outdoor Leader School trip in India, on which I watched a classmate pass away, I have a renewed sense of responsibility to my community. How can I help? I want to start getting my undergraduate degree this semester, despite the deadlines having been passed for applications (I just got home from India). I want to know where I should start, what types of paths are open to me, and other ways that I can help.
3:46 Dear Andrew. This is Dr. Dawson. There are many ways to get involved! You can volunteer at a local program for children with disabilities, become an advocate (see Autism Votes LINK), join a walk for Autism Speaks (LINK), or get involved with other college students (Autism Speaks U LINK). You can find the local groups who are providing early autism intervention services and train to be a therapist. There are many career options including becoming a clinician (physician, psychologist, occupational therapy, speech-language therapist), a teacher, a scientist, or lawyer, to name a few. It truly takes a village to support people with autism and other disabilities. I’m glad you are eager to help.HERE ARE THE LINKS:

Comment From MelissaMy 11 year old son was just diagnosed with Asberger’s what are the best programs for him to get into especially for his socialism skills? What can I do to help him control anger issues?
3:48 Dear Melissa, Children with Asperger syndrome are often helped by behavioral interventions that focus on social skills training. There are also interventions (Cognitive behavioral therapy) that can help with anxiety which is common among children with Asperger syndrome. Anger/emotion-regulation is often a challenge. Again, there are behavioral strategies that can be used to teach your son to better manage and appropriately express his feelings. Clinical psychologists are typically well-trained in these therapeutic methods. You should check in your area for a clinical psychologist who works with children and/or chidlren with Asperger syndrome and also check out the resources in your area on this link:

3:49 Hey everyone: When we posted the link to the resource “library” earlier, we meant THIS link to the resource “Guide.” Here it is again: http://www.autismspeaks.org/family-services/resource-guide
3:50
Comment From TrishMy 3 year old daughter has autism, and she will not sleep much. Hardly ever, no matter what I do. And when she manages to fall asleep she only sleeps a couple hours. I’ve tried schedules, melatonin, wearing her out, relaxation techniques. Is there anything that you could reccommend that works especially well to make autistic children sleep? I’m just so tired!
3:52 Dear Trish – this is Dr. Horrigan. I know it is very very tough to have a child that awakens frequently duirng the middle of the night. It will get better, I promise you, although it may take time. Behavioral contributions are always important to look at. One thing to think about is whether there are unitended reinforcers (rewards) that are occurring on a behavioral level that might be reinforcing her middle-of-the-night awakening (inlcudes letting her get in bed with you after she awakens). I am sure you have already thought about this. The other issue is whether she is accustomed to only a very specific set of cues (e.g. a CD with lullabies playing as a backdrop), associated with being able to fall asleep initially, that can be readjusted. In terms of meds, melatonin only helps with sleep onset, not continuity of sleep (staying asleep) and it shouldn’t be given during the middle of the night (e.g. after midnight) – it can make things worse the next night if it is given that way, because it can distrub the individual’s circadian rhythm. I would have a consultation with a sleep specialist, if you can do that, and this will allow you to discuss other medication possibilites that may be more effective with middle-of-the-night awakenings such as off-label miniscule doses of trazodone or mirtazepine or doxepin, although these meds for a 3 y.o. require a sleep specilist to be involved. You also could get some good behavioral tips from a sleep specilaist that are tailored to your daughter’s unique sleep habits. By the way, on February 14th, we will put up on our web site a “tool kit” on sleep hygiene that I think will be very helpful to parents.
3:53
Comment From GuestHi, my son has ASD, he is 4 sometimes appears to have visual stims when asked to tasks or when he wants something. Is this a behavior or part of the spectrum. His teachers special preschool are stumped?
3:54 Hello Guest at 3:12. This is Dr. Dawson. Is it not common for a child with autism to engage in self-stimulatory behavior when he is nervous, upset, excited, frustrated, or even just wishes to communicate something. It would be helpful to try to understand what is the function of the visual stims. You can do some detective work by recording when it happens and then making a guess what the function is. If your child is trying to communicate something (e.g. This is exciting! or I don’t like this) then you can model for your child the appropriate behavior. If the function of the behavior is to calm himself, then using other ways of calming your child may help. The fact that your child stims when asked to do a task suggest that he might be telling you that the task is either something he doesn’t like or alternatively something he is excited about. If he doesn’t seem to like the task, consider ways of changing the task to make it more appealing (easier, broken into smaller parts).
3:59
Comment From StephanieMy 20 month old daughter has had 3 EEGs and her ped neurologist said they show “sluggishness” with her brain activity. No definite diagnosis yet. However, he suggests she be seen by a Dev ped. We have an appt end of March. I’ve searched and can not find any relation between sluggishness and ASD. Any thoughts?
4:00 Dear Stephanie – this is Dr. Horrigan – I think they probabaly meant “slowing” rather than “sluggishess”, with regard to the wave length frequency of the most common waves seen on your daughter’s EEG. It is not a very specific finding, frankly. It would depend on whether the slowing is localized to a specific part of her brain, or if it is generalized (all over), to know if it is a patten that is clinically meaningful and amenable to treatment (e.g. medicines, like anti-seizure meds). . Slowing is associated nonspecifically with developmental and intellectual disabilites, and may (or may not) be associated with a future risk of seizures. Seizures are diagnosed clinically, by the way (e.g. by observing them directly in the affected individual). Enriching your daughter’s daily life with diffenet types of sensory stimulation (presuming she can tolerate this) and behavioral therapies (e.g. ABA) can also be associated with the lessening of EEG slowing, and rehabilitation, in general .
4:01
Comment From Lori GraysonAs my son gets older, he is now 10, I find he is more forceful with having to maintain an exact schedule and even less flexible than when he was more non verbal. Do these children ever become more flexible with changes. He also still has separation anxiety hen it comes to me, not so much my husband.
4:01 Dear Lori, As your son gets older, he may be developing a stronger sense of what he like and doesn’t like and now has the ability to express himself. So, that may be part of what you are seeing. You mentioned, however, that he is also showing some symptoms of anxiety and it makes me wonder whether your son’t increase in rigidity might be a part of an anxiety disorder. Autism is often associated with anxiety symptoms. I would encourage you to have him evaluated by a child psychiatrist or clinical psychologist. There are specific interventions, such as cognitive behavioral therapy, that can help. In addition, medications are often helpful.
4:03 Advance question from Krista
My 14 yo son has a diagnosis of Asperger’s. Last year he had his brain mapped with an EEG, and subsequently did 16 weeks of neurofeedback therapy. My son has done many, many therapies over the years, and neurofeedback was the first (other than speech articulation) that seemed to make any difference. His interest in engaging with others and his ability to socialize successfully increased. His executive function skills improved. Family members and others, including his music therapist, noticed as well–even his guitar playing improved noticeably. What does the research say about neurofeedback in ASD individuals? Is this an area of research you are funding?
4:03 Krista: This is Dr. Horrigan. It’s really great that your son is doing so much better, and if neurofeedback played an important role in getting him there, then I think that is wonderful. There are some small studies that have reported positive results with neurofeedback in individuals with autism, with success rates ranging from 1 in 4 to 4 out of 5. But it is not clear to me if publication bias is playing a role (e.g. only the positive studies get written up and published). My experience has been closer to the 1 in 4 success rate, and success seems to be very dependent upon the expertise and charisma of the trainer, the commitment of the family, and the level of disability of the individual with autism (lesser levels of disability seem to be associated with greater probability of improvement with multiple rounds of neurofeedback). It is also expensive, and it can be very tough to get insurance to pay for it, so that is a pragmatic consideration. If a family wants to pursue neurofeedback for their loved one, I would recommend working with the neurofeedback therapist to articulate a very clear idea of what success needs to look like, even after the first 5 sessions, so that they can get out early, before having to spend too much money, if the ultimate likelihood of success looks like it is going to be limited. One important upside of neurofeedback, when it does work, is that the rates of sustained improvement are quite good and success can be sustained with periodic ‘booster’ sessions

Comment From ShellyMy son is 3 and was diagnosed in August. We have been told by numerous people to cut out any red food dyes from his foods. Woudl this be beneficial? He had one episode of vomiting after drinking a juice loaded with red dyes and everyone is telling us to just cut them out, but everything has red dye in it that kids want to eat. Any advice would be great. Thanks!
4:06 Dear Shelly – this is Dr. Horrigan – there is decent evidence that a subset of kids (with or without autism) are senstiive to artifical food colors and dyes. Some red, yellow and blue dyes are especially likely to have this type of association in susceptible individuals. Oftentimes, after incidents like the one that you described (the vomiting), the only way to get close to a definive answer for your child is to scrupulously eliminate that potentially offensive color (e.g. that red dye, in this instance) and then see if things settle down for your son. I know it is a hassle because red food dye/color is failry ubiquitous, all over the place in foods that we all eat, but it is worth trying to get it out of your son’s diet to the extent that you can, to test out your theory. You could be right.
4:08 Advance question from Jolanta:
Hello. My son who is 6 years old is autistic. We live in the United Kingdom. We are considering having another child, but afraid of a possibility that a new child would develop autism. What are the chances? I’m 39 so I need to decide soon. Thank you.
4:09 Hi, Jolanta. This is Dr. Dawson. In the past year, there was a new study that was published that examined the risk for autism spectrum disorder in younger siblings. Although each individual family’s situation is unique, at a population level, the overall risk of a sibling of a child with autism developing the disorder is about 19%. We have summarized the new information on risk rates and had a webchat specifically devoted to that topic. I hope you find this information useful.

4:11 Advance question from Desray: Hi my son is 5 an half yrs old. He’s stll in nappies and I’m finding it very hard to get him out of them. The problem I’m havin is that,he nows how to wee in the toilet but he does not want to put underpants or shorts on after his visit to the loo. I’m realy having a hard time dealing with this disorder. He’s my only child and I’m scared for him. I would also like to no if Risperdal or Ritalin is ok for Autistic kids to take. Sometimes Jose has some serious meltdowns sometimes and I feel like I need to give him something. Plse help. I’m from South Africa where we don’t have much assistance. Thank u for all that yull do. God Bless.
4:12 Dear Desray, This is Dr. Dawson. It is terrific that your son is now able to wee in the toilet. That is half the battle! I suggest that you create a series of pictures (these can be photos, drawings, or clippings from magazines) that illustrates the series of steps involved in going to the loo. This would include not only weeing in the toilet, but also pulling up his pants, washing his hands, and so on.Below is a link that describes how to develop these visual supports. You should begin by giving him a reward (this can be a physical reward, praise, food, whatever he likes) after he wees in the toilet. Then, slowly add each new behavior over time, encouraging him to carry out the next step and then rewarding him. Over time, you can start to withdraw the amount of help you provide and rewards for each step as he becomes more capable of doing it on his own. Keep in mind that pulling on his underwear and shorts requires many skills – motor skills and thinking skills – so you may need to provide both the pictures and physical help for a while.Regarding your son’s meltdowns, you should start by keeping a record of when he has those meltdowns and see if you can figure out why. Is it because he is tired? Is there a specific activity or environment that is upsetting? Is he trying to ask for something but doesn’t know how? Use this information to make adjustments in his environment and routine to try to avoid the things that are upsetting. If he is frustrated because he is trying to request something, prompt him to use a more appropriate way of expressing his needs (he could point to a picture, touch what he wants, or say a simple word) and then immediately reward him for using the more appropriate behavior. Talk to your son’s teachers to see if they have suggestions too.Autism Speaks will soon be publishing a new tool kits for handling challenging behaviors – so keep looking on our website for that. We also have a tool kit that can help you decide whether you should consider medication (LINK below). It is best to see if behavioral strategies are effective before turning to medications.HERE ARE THE LINKS:

Comment From MaryMy son is now 23 has aspergers and has had stomache problems all his life I now have done some research and have him on the following B12 500mg, super b complex w/ vitaminc and folic acid , Acetyl L-Carnitine 400mg. Taurine 500 mg,Vitamin D-3 5000 iu, Co-Q Max plus Ginkgo.Advanced Acidophilus Plus , Prevacid 30 mg And Prozac 60mg We have seen great improvement since we started especially in the stomache area and he seems to be more talkitive so much so we are now doing twice a day . He used to drink 2 Monster drinks a day and ask me why he cant feel normal like when he drinks those drinks so I researched whats in them Whats your thought on this and is there anything that you would add?
4:14 Dear Mary – this is Dr. Horrigan – it sounds like your son is feeling a lot better and i am very grateful for that. In terms of what he is taking, the only thing that came to mind immediately is to make sure that he is not too overboard on the B6 (e.g. I usually go up to 100 mg, max). I would need to know the exact compostion of the Super B to give you a more sophisticated comment about other potential yellow/red lights. The Monster drinks are probably ‘benficial’ for your son due to their load of caffeine and sugar. I would rather he try coffee, if he really feels that needs that extra benefit provided by cafeine. Just being practical here…
4:15 Advance question from Mel:
Hi, I never done this before but I was wanting to ask a question. I have a 12 year old son with autism and a 4 year old daughter who I think has autism. We’ve had her tested and she shows a lot of autistic traits. I was told that because she can respond when they say hi, how are you, that she isn’t autistic at all. Is it possible that they misdiagnosed her? Should I try to find somewhere else to take her? Thank you.
4:15 Dear Mel, This is Dr. Dawson. I’m glad you asked your question. If you feel that your daughter may have autism and the doctor you saw missed it, you should seek another opinion. Siblings of children with autism sometimes have difficulties in areas related to autism, such as social and language skills, without meeting full criteria for autism. Even if your daughter is found not to meet criteria for autism, she should receive help in the areas she has difficulty in, whether that is language, learning, or social behavior.
4:17 Advance question from BA Travis:
I am looking to see if there has been any research or if any of the Drs. would be able to tell me about links to high exposure to pharmaceuticals and ASD.
The background is while I was pregnant I was working in a pharmeceutical facility that manufactured over the counter cold and pain medications. I was exposed daily to high volumes of raw powdered chemicals. I asked to be transfered but was denied. We were required to ware dust masks when pouring the powdered materials but that was it. I had a healthy baby after over 20 hrs of labor but by 2.5 he was diagnosed with being high functioning Autistic. At 5 he is on par educationally for his age but tests at around 30 months for speech and has trouble with focusing on the task at hand. Before I left the company over a year ago an environmental quality manager was brought in to do air testing and before long all personel working in the same areas as I was were being required to ware tyvek suits with battery operated air respirators.
The thought has been in the back of my mind but not being able to find anything online on a link but after the drastic change in the way the employees now have to handle the product has brought that thought to the forefront.
Any thoughts?
4:17 Dear BA Travis: This is Dr. Horrigan. While you have provided a limited amount of information here, it does sounds suspicious that the company changed its policy to require the use of specialized equipment by workers ostensibly to prevent hazardous exposure to something in the workplace. I would need to know specifically what chemicals that they had you handling, to have a more sophisticated insight into the potential relationship of in utero exposure to those chemicals and neurodevelopmental disorders. This is the type of inquiry that we are very interested in and we have funded and are funding several lines of research to help identify the relevant prenatal risk factors arising from the environment that are associated with autism.
4:19 Moderator’s note to BA Travis: You can send more info/reply after the chat to sciencechat@autismspeaks.org.
4:20 Advance question from Vanessa:
My 7 year old son has been diagnosed with pdd-nos, anxiety and adhd. Currently he is having a hard time at school connecting with other children. He is obsessed with Hello Kitty and gets picked on by the kids in his class. Recently he is telling people he is a girl or that he wishes he was a girl. He is also introducing himself as his younger brother. I can kind of deal with all this but he seems to be increasingly aggressive lately and hurting himself. I am concerned because I am afraid he will really harm himself or another student. Is there anything I can do to help him? Usually he is pretty easy to work with and calm down but recently he just seems so angry. He is currently on a low dose of Zoloft and Intuniv.
4:21 Vanessa: This is Dr. Horrigan. The first thing that question that came to my mind is whether there are any easily identifiable factors occurring in your son’s school environment that are causing him to feel so distressed. For example, I am worried that he may be getting bullied, perhaps by multiple classmates. And it may be sneaky bullying, it’s hard to tell. Either way, any type of bullying would be completely unacceptable. Have you had a chance to discuss the issue of triggers for his aberrant behavior with his teacher(s), and/or the Exceptional Children’s coordinator, and have you had a chance to observe him in the school setting yourself, to see what may be associated with his distress? I also wonder if they might be pushing him too hard, with regard to the curriculum. Again, it’s hard for me to say. You need more information from the people at school. In terms of the medications, I am not sure how long your son has been taking Zoloft and Intuniv, but both can cause paradoxical heightening of anxiety as well as paradoxical worsening of irritability (it is more common when first starting Intuniv, in my experience). If you suspect that the medications may be worsening things, then talk to your son’s doctor and discuss a trial off one or both of the medication(s).
4:24 Thank you all so much for joining us, and we’re sorry we weren’t able to get to all your questions. Please join us again next month, on March 1st, with your questions. We’re going to invite a gastroenterologist with expertise treating those with autism to address your many GI concerns. Thanks again and be well!Dr. Dawson and Dr. Horrigan

New Findings on Sensory Overload: A First-Person Perspective

February 2, 2012 15 comments

Guest blog post from Autism Speaks Science Board Member John Elder Robison, author of Look Me in the Eye: My Life with Asperger’s and Be Different: Adventures of a Free-Range Aspergian

According to a press release I received this morning, new research from Cold Spring Harbor Lab might help explain how a gene mutation found in some autistic individuals leads to difficulties in processing auditory cues and paying spatial attention to sound. [Editor’s note: See our related science news story on this Autism Speaks-funded study.]

The study found that when a gene called PTEN is deleted from auditory cortical neurons—the main workhorses of the brain’s sound-processing center—the signals that these neurons receive from local as well as long-distance sources are strengthened beyond normal levels.  That’s the first interesting part of the study.

PTEN has been associated with autism in a number of previous studies. In particular, the PTEN variation has been found in autistic people with larger heads, and it’s suspected as a cause of both additional connectivity in the brain and additional brain cell growth.

How many of today’s autism population have a PTEN variation?  Do you?  No one knows.  It’s one of many genes researchers are studying.

What I do know is that I have abnormal sensitivity to sound, as do many autistic people. Many of us are easily overwhelmed by noises that go unremarked by the rest of the population. For some time, I have realized my excess sensitivity is a two-edged sword. On the one hand, it gave me powerful insight into music and facilitated my earlier career in rock and roll. On the other hand, it has often put me at a disadvantage as I’m rendered inoperative by what others see as ordinary situations.

It’s interesting to read that PTEN may be a cause of that difference. Understanding the genetic foundation of why that happens doesn’t do me much good, but the next part of the study might:

Researchers found that those can be blocked by rapamycin, a drug currently in use as an immunosuppressant. Rapamycin as an autism therapy has been studied before and found beneficial in some cases. This study is one of the first that sheds light on “why” and speaks to a specific mechanism by which we may be disabled.

Now that I’ve come to know many people on the spectrum, I realize I am one of a fortunate few who have significant sensory sensitivity without being disabled by it.  The vast majority of autistic people who write about sensitivity do so in the context of disability. If there were a way to reduce sensory overload, I’m sure a number of folks on the spectrum today would like to hear about it.

One next step might be to see if rapamycin has the same effect in humans, and what other unforeseen effects it may have. Rapamycin has already been tried as a therapy in other contexts relating to autism. A targeted study that looked at the drug’s effect specifically on sensory overload would be very interesting.

It’s possible that this research illustrates a first step on the path to remediating a specific component of disability for many people on the spectrum. Much more testing will be needed to really know if that’s true, but it looks like a promising start.

My biggest concern is that rapamycin may have unforeseen effects elsewhere in the brain, and we won’t be able to understand that until we have conducted a sizeable human trial. We can only do so much by observing and extrapolating from mice.

An interesting aside is that Dr. Zador’s research further supports the emerging idea that excessive brain plasticity is a key component of the brain differences that lead to autism. His research premise is that the PTEN variation causes excess connectivity, and connectivity is a key element of plasticity. I’ve written about that idea in earlier posts.

I read a lot of talk in the autism community that questions why we spend money on genetic research when today’s autistic population needs help now. There is a popular perception that genetic research can only benefit unborn generations, or even worse, be used as a tool for selective abortion.

Dr. Zador’s study shows a clear pathway from a basic genetic study to a possible therapy for autistic people today, if they suffer sensory overload issues. It’s a perfect example of why this kind of work continues to be important and needs to be funded alongside all our other efforts in the autism research arena.

One of the pathways regulated by the PTEN protein involves shutting down an intracellular enzyme called mTORC1, which promotes cell growth, among other things…. While Zador is excited about “this finding that suggests that mTORC1 could be a good therapeutic target for some cases of PTEN-mediated brain disorders,” he is also keen to further pursue his team’s new evidence that cortical hyperconnectivity could be the “final pathway” by which diverse ASD genetic pathways lead to a single ASD phenotype. “Using cortical connectivity as a paradigm for assessing ASD candidate genes could provide insights into the mechanisms of the disorders and perhaps even give us clues to formulate new therapeutic strategies,” he states.

Dr. Zador’s leap from a subtle variation in genetic code to a specific behavioral aberration represents a brilliant leap of intuition and reason, backed up with careful lab work. It’s the kind of result I hope to see when I cast my vote for further genetic studies. This work was originally funded by Autism Speaks and NIH four years ago.

Here’s another really fascinating point to ponder. The PTEN genetic variation has been already associated with certain people with severe autistic disability and people with tubular sclerosis. Now, by associating PTEN with auditory sensitivity, we confront the question:  Do people like me have the PTEN difference too?  No one knows, because that study has never been done.

I’ll just say one more thing in closing. The discovery that PTEN aberrations can lead to sensory overload, and the pathway by which that happens stands separate from any question about rapamycin as a therapy. Don’t let worries about a particular drug blind you to the significance of the first finding.

Other researchers are looking at alternate ways to affect cortical plasticity in general and even connectivity as described in this study.  Rapamycin may end up being a therapeutic answer for some, but it’s equally possible that a better therapy will be developed now that we are beginning to unravel the underlying issues. One day, autistic people who are disabled by auditory overload may be able to “mute” the disability, while retaining enough sensitivity to be exceptional.

That, folks, is what the science is all about.

Adults with Autism: Sharing Ideas, Filling the Gaps

January 30, 2012 30 comments

Guest post by Merope Pavlides, editor of AutismAfter16.com, author of Animal-assisted Interventions for Individuals with Autism and mom to two sons, one of whom is on the autism spectrum.

Autism is not a condition of childhood. Autism follows the person. It follows the person into the workplace, the community, adult relationships and health care. Until recently, however, little attention has been paid to issues surrounding adulthood with autism. Fortunately, we have now begun a national dialogue, and Autism Speaks is bringing its voice—and resources—to the discussion in a big way.

On January 26th, Autism Speaks held a research summit entitled, “Adults with Autism: Sharing Ideas, Filling the Gaps,” in Chapel Hill, NC. The event was co-hosted by Extraordinary Ventures, a model employer of adults with autism. Extraordinary Ventures was founded by Autism Speaks supporters and parents Lori and Gregg Ireland.

The meeting brought together many premier scholars on adult autism issues, as well as Autism Speaks representatives, autism service providers, parents and donors. My husband, Peter Emch, and I were invited to participate as parents and long-time supporters of Autism Speaks. The very fact that Autism Speaks included parents in an event like this is hugely meaningful, because it grounds the research agenda in real-world experience and need.

Moderated by Autism Speaks Chief Science Officer, Geri Dawson, Ph.D., the meeting provided the opportunity for investigators to present overviews of current research projects funded by Autism Speaks and for all participants to ask questions and share ideas. The morning session showcased studies aimed at describing autism spectrum disorder (ASD) in adults, while we spent the afternoon with prescriptive research involving topics such as how to improve interventions.

Morning keynote speaker Marsha Mailick Seltzer, Ph.D., of the University of Wisconsin’s Waisman Center, outlined “Trajectories of Development in Adolescents and Adults with ASD.” Afternoon headliner Paul Shattuck, Ph.D., of Washington University, discussed “Service Use and Outcomes among Youth with ASD.” I found it interesting that both Seltzer and Shattuck noted that, despite few published studies on adults with autism, there is an abundance of data awaiting analysis. This means that we need to be investing resources in finding the meaning in the information that’s already available.

As a parent of a young adult with autism, it’s gratifying to sit in a room with so many smart, energetic people and learn that they want to bring their talent and enthusiasm to bear on the same issues that worry me as a parent. I’m also a special educator. As such, I’m so glad to see researchers demonstrating concern for how academic findings translate into real-life practice. While it’s crucial that we continue to deepen our understanding of what life is like for adults with autism, it’s just as important to make immediate progress in improving their lives.

I was especially excited to hear so much conversation on the topic of our adults as learners. As a society, we tend to think about the autism service system for adults as involved exclusively in care giving. Rather we need to develop dynamic supports that provide ongoing opportunities for personal growth and development. The summit allowed those who are studying adult needs to connect with those who are examining skill-building models. It’s this type of collaboration that fosters new programs that not only look good on paper, but also work in the real world.

Finally, participating in an event like this reminds me of how important it is for families to understand that they are integral to the research process. Sometimes we feel as though investigators go about their work in ivory towers without understanding the real needs of those on the ground. As families, we must be active participants in the research process. Not only in the sense of filling out questionnaires and providing information, but in terms of actively making use of the knowledge emerging from this research. That doesn’t mean we need to bury our noses in scholarly journals. It does mean that we need to enter into thoughtful discussion with scientists about how to incorporate what they are learning into what we need from adult service providers. Good scholarship is being conducted through Autism Speaks funding. As a community, let’s not allow it to happen in a vacuum.

I’ve been reading news reports that it might be possible to detect autism by watching how much a 1-year-old focuses on a speaker’s mouth. Is this true?

January 27, 2012 4 comments

This week’s “Got Questions?” answer is from Autism Speaks Chief Science Officer Geri Dawson, Ph.D.

In recent days, you may have read media stories about research showing that typically developing babies tend to switch from eye gazing to lip reading when first learning to talk, but then switch back to focusing primarily on a speaker’s eyes by 12 months. The research report appears online this week in the Proceedings of the National Academy of Sciences.

In reporting their results, developmental psychologist David Lewkowicz and doctoral student Amy Hansen-Tift, of Florida Atlantic University, suggest that this shift in focus may be different for infants who have autism spectrum disorder (ASD) or are at risk for developing it. Taking this idea a step further, they propose that paying attention to how babies shift their focus during their first year of life might help identify infants at risk for ASD – perhaps before other obvious symptoms emerge. To back their idea, they cite previous research suggesting that 2-year-olds with autism tend to look mostly at the mouths of those speaking to them, while typically developing 2-year-olds focus mostly on eyes.

It’s an intuitively appealing idea. But in truth, past studies have not consistently supported this notion that children with ASD focus less on eyes and more on mouths.

It is true that children with autism tend to pay less attention to social actions such as expressions. However, it’s possible that children with autism, like typical children, show a similar pattern of paying more attention to the mouth when they are learning language.

Given that language delays are common among children with autism, one would predict that this language-acquisition period might be prolonged. In addition one would expect that mouth-versus-eyes gaze patterns would vary among children with ASD depending on each child’s level of language skill.

Fortunately, while we don’t yet know whether eye gaze is a reliable predictor of ASD, research solidly supports the usefulness of other signs for screening toddlers. The American Academy of Pediatrics (AAP) recommends that all children receive autism screening at 18 and 24 months of age. One of the AAP’s recommended screening tools is the Modified Checklist for Toddlers, or M-CHAT, which you can access on our website, here. Please also see our Learn the Signs resource page.

Meanwhile, Autism Speaks continues to fund a wealth of research on early screening and diagnosis because evidence suggests that early intervention improves outcomes. You can explore these and other Autism Speaks studies here. This research – like all the resources Autism Speaks develops and offers – is made possible by our families and supporters. Thank you for your support.

Autism and Associated Medical Conditions

January 24, 2012 18 comments

Guest post by epidemiologist Laura Schieve, Ph.D., of the National Center on Birth Defects and Developmental Disabilities, at the Centers for Disease Control and Prevention.

In recent years, several reports have suggested that children with autism or other learning or behavioral developmental disabilities are more likely than typically developing children to have health conditions such as respiratory or gastrointestinal illnesses.

However the studies behind these reports were often small and showed inconsistent findings. Some of their methods had limitations. One of the biggest problems was that they didn’t adequately compare children with different types of developmental disabilities. Because of these limitations, many public health professionals and healthcare providers have been skeptical about whether children with autism or other behavioral developmental disabilities truly faced an elevated risk of other medical problems.

My colleagues and I wanted to help paint a clearer picture of this important public health issue. Our study, recently published in the journal Research in Developmental Disabilities, compared the medical conditions and healthcare needs of children with developmental disabilities with those of children without developmental disabilities. We also compared children with autism with those who had other developmental disabilities.

We assessed children included in the National Health Interview Surveys from 2006 to 2010. Households throughout the United States are randomly selected to participate in this annual survey. In households with children, one child is randomly selected to participate. Each child’s parent or other primary caregiver is interviewed in-person about the child’s health and development. Interviewers asked whether a doctor or other healthcare provider has ever told them the child has certain conditions including autism and several other developmental disabilities. We also ask if the child has a health condition such as asthma or has experienced other symptoms such as frequent diarrhea or colitis in the past year.

We included more than 41,000 children aged 3 to 17 years in the study. Of these, 5,469 had one or more of the following five developmental disabilities:  autism, intellectual disability, attention deficit and hyperactivity disorder (ADHD), learning disability or other developmental delay.

As a group, these children had higher than expected rates of all of the medical conditions we studied. More specifically, they were:

* 1.8 times more likely than children without developmental disabilities to have ever had an asthma diagnosis,

* 1.6 times more likely to have had eczema or a skin allergy during the past year,

* 1.8 times more likely to have had a food allergy during the past year,

* 2.1 times more likely to have had three or more ear infections during the past year,

* 2.2 times more likely to have had frequent severe headaches or migraines during the past year, and

* 3.5 times more likely to have had frequent diarrhea or colitis during the past year.

These increased rates of health conditions held true even for children diagnosed with ADHD or learning disability, but not diagnosed with autism or intellectual disability.

However, one finding stood out in particular when we compared the developmental disability groups to each other: Children with autism were twice as likely as children with ADHD, learning disability or other developmental delay to have had frequent diarrhea or colitis during the past year. They were seven times more likely to have experienced these gastrointestinal problems than were children without any developmental disability.

This detailed assessment demonstrates that children with autism or many other types of developmental disabilities do, in fact, face an increased risk for many common health conditions. This, in turn, provides evidence that children with developmental disabilities require increased health services and specialist services, both for their core functional deficits and for health problems beyond their core developmental disabilities.
