ADHD & Fetal Development

 

Obviously, being pregnant can be stressful in itself, but current research shows that stress can affect fetal development which may lead to long-term problems including ADHD.

Dr. Vivette Glover of Imperial College London, surveyed pregnant women at her hospital. Of these, nearly one quarter felt anxious and depressed due to stressors including work, money, arguing with spouse, and moving to accommodate a larger family. When compared to their non-stressed counterparts in this research, the babies of the stressed mother had lower birth weight, lower IQ, slower cognitive development, and more anxiety. Lower birth weight has been an indicator for coronary heart disease in later life.

In 2007, research in the Journal of the American Academy of Child and Adolescent Psychiatry indicated that being stressed during pregnancy is as detrimental for the baby’s development as smoking or being obese. Glover’s research reveals why and how this happens: stress produces the hormone cortisol. An abundance of stress can actually diminish the barrier enzyme that inhibits cortisol from reaching the fetus. Costisol impacts fetal brain development.

According to Glover, “People used to think that if something was congenital, apparent at birth, it had to be genetic. In fact it can be an in-vitro reaction of genes and environment.”

Glover also contends that her research shows stress greatly increases the likelihood of a child having ADHD (attention-deficit hyperactivity disorder), cognitive delay, autism , anxiety and depression. 

Glover’s research reinforces previous data from the UK where stress was shown to increase the risk for development of ADHD. In that research, the women who experienced the most stress doubled the chances of developing ADHD.

“The organs are forming during the first trimester of pregnancy, but the brain is developing all the way through,” Glover explains. “The organs are sensitive while they are forming and, once formed, they are harder to change.”

“In evolutionary terms, stress perhaps prepares the child for survival in a stressful environment. If a child is anxious and has attention deficiency, it will be very alert to danger. This may once have been adaptive, beneficial for the child, but it isn’t any more,” Glover says.

Significantly, Glover’s research implies that the changes may be on a genetic level so that it may be passed on generation to generation.

Therefore, it’s important to realize that taking care oshutterstock_3753070f ourselves during pregnancy is more important now than ever. Small efforts like seeking health services early, meditating, eating a balanced diet, taking pre-natal vitamins, and laughing are good practices.

Minimizing stress by maintaining a consistent schedule both at work and at home is a good idea.

 

Meditation & ADHD

Sunset & Sky 098 Researchers, Dr. Zylowska, et al from the University of California-Los Angeles conducted a feasibility study of an 8-week mindfulness training program for adults and adolescents with ADHD. Their report was published in The Journal of Attention Disorders (2008 May;11(6):737-46. Epub 2007 Nov 19).

The researchers sought to inquire whether mindfulness meditation could improve attention, reduce stress, and improve mood. The researchers recruited 34 adults and 8 adolescents. Study participants were given a weekly training session. They were also required to practice daily starting with 5 minutes of meditation per day and gradually increasing to 15 minutes per day.

The majority of participants (after dropouts) reported improvements in self-reported ADHD symptoms. Independent tests on tasks measuring attention and cognitive inhibition also indicated improved symptom outcomes. Improvements in anxiety and depressive symptoms were also observed.

In yet another pilot study conducted by Sarina J. Grosswald, Ed.D., a George Washington University-trained cognitive learning specialist, a group of middle school students with ADHD were required to meditate twice a day in school. After three months, researchers found over 50 percent reduction in stress and anxiety and improvements in ADHD symptoms.

"The effect was much greater than we expected," said Sarina J. Grosswald, Ed.D., a George Washington University-trained cognitive learning specialist and lead researcher on the study. "The children also showed improvements in attention, working memory, organization, and behavior regulation."

Due to the neuroplasticity of the brain, better attention can be attained through meditation. Buddhist monks have been doing it for centuries. This seems to be true of ADHD persons as well. However, it is quite apparent that attention difficulties are just the tip of the ADHD iceberg. Other skills including organization, filtering out distractions, memory, time on-task, motor skills, visual tracking, etc, are typically diminished in ADHD persons. A complete program like Play Attention is required to teach these skills.

As for meditation, it is likely a good supplement to training in the aforementioned skill areas, but given the nature of the cited studies, a controlled clinical study is warranted.

Dopamine & ADHD

thinkingm4  The Journal of the American Medical Association (JAMA. 2009;302(10):1084-1091) recently published work by Dr. Nora D. Volkow, MD, et al regarding evaluation of the biological bases that may reveal a reward/motivational deficit present in the brains of persons with ADHD.

Volkow and her colleagues theorized that ADHD may be connected to reward-motivation deficits. Volkow investigated whether lack of motivation and its relationship to reward could be traced to depression of dopamine in various areas of the brain.

To determine whether dopamine was depressed in ADHD persons, the researchers used positron emission tomography (PET scans) to measure dopamine levels in 53 nonmedicated ADHD adults and 44 healthy non ADHD adults between 2001-2009.

Since the biological mechanisms of ADHD are unknown, studies of this type have become the holy grails of research. While Volkow’s credentials are quite impressive (NIH, NIDA, etc.) this research is not new or conclusive. The theory that dopamine dysfunction/depression may be involved with ADHD symptoms has been researched for many years.

Furthermore, Volkow’s  small sample size consisted only of adults and therefore should not be extrapolated to include the child population. The small sample size alone should prevent it from being generalized to the entire adult ADHD population. One has a problem of antecedence here; is ADHD caused by dopamine depression in the brain? Or is the dopamine depression the result of ADHD that was acquired by other biological means? This research cannot answer that question.

What does the research tell us? It tells us that for some adults, dopamine may play a role in ADHD. For those adults, taking a stimulant medication may increase dopaminergic activity thus increasing reward/motivation responses and thus increasing attention to task. That might be a stretch.

On the downside, persons with depressed dopamine levels would probably greatly enjoy using stimulants. Study participants reported this. This may contribute to the frequent incidences of substance abuse among ADHD persons.

The authors write,"Despite decades of research, the specific neurobiological mechanisms underlying this disorder still remain unclear. Genetic, clinical and imaging studies point to a disruption of the brain dopamine system, which is corroborated by the clinical effectiveness of stimulant drugs (methylphenidate hydrochloride and amphetamine), which increase extracellular dopamine in the brain."

Unfortunately, the study leaves us with more questions than answers. Does it tell us what happens long term? Does it tell us of side effects?  Does it tell us if this actually applies to children? Can we conclusively determine a causal relationship between reward/motivation and ADHD? Does it solve the problem of antecedence? Do we know anything conclusively about all ADHD adults. No. There’s still a long road ahead.

ADHD and Genetic Research

Research over the past decade has been relatively inconclusive regarding the etiology of ADHD and its genetic links. The January 07, 2009 special issue of American Journal of Medical Genetics (AJMG): Part B: Neuropsychiatric Genetics presents a comprehensive overview of the latest genetic research of ADHD. In search of the ADHD holy grail, researchers have attempted to identify specific genes that underlie the disorder in the hopes that gene discovery will lead to better treatments for the disorder.

The studies cited in the AJMG indicate that one genetic marker may be associated with ADHD symptoms with the possibility that many genes are involved in ADHD. Each of these genes may play small roles in their overall presentation of ADHD symptoms. The currents studies then are inconclusive and suggest the need for larger studies a) to determine if there are genetic mechanisms underlying ADHD, b) to determine what these mechanisms do if they exist, and c) to determine whether these initial findings can be confirmed.

An important issue needs to be raised here: If one can find a genetic marker and the various genes involved in ADHD, is it therefore a disease like diabetes, cancer, or atherosclerosis? Or is it a genetic trait like red hair, crooked teeth, or freckles? Personally, it seems to me to be more of a trait than anything else. Even the noted ADHD expert, Dr. Ed Hallowell and his colleague, Dr. Peter Jensen, have indicated they perceive ADHD as a trait.

The second issue that needs to be raised here is: What is it that the researchers can do with the genetic information they are seeking? The answer to this question is medication. Most of the genetic studies have leaned toward a genomic search for genes that may someday be used to predict which children respond most favorably to the stimulant medications. The current studies indicate that, although there are likely to be genetic factors that are associated with stimulant efficacy in children with ADHD, there are no single genes with a very large impact on treatment response. This may be because ADHD is a conflation of diffused attention, poor organization, hyperactivity, etc. Are there genetic markers for each of these individual characteristics?

This presents us with the problem of antecedence (chicken or the egg). It appears that ADHD is a conflation of a variety of characteristics. This is precisely how it is diagnosed. These characteristics could be acquired in one of two methods: They could be genetic (heritable) or they could be learned. One can learn to be disorganized, hyperactive, or even have diffused attention. Most of us experience this now in our busy, noisy existence on this planet. Does this change our genetic makeup?

We know that when we learn something, certain genes are switched on which activate messenger RNA to build neural networks supporting long-term memory. Therefore, we are substantially changing our genetic makeup. The brain is incredibly malleable or labile. This is both significant and promising. We can and do shape it through our various daily activities. It would hold then, that we can change our diffused attention into focused attention, our disorganization into organization, and our hyperactivity into calm behavior. However, if we obdurately argue that ADHD is a disorder or disability, then hope for this change is diminished if not extinguished. Now is the time to realize that there is hope for persons with attention challenges; change is quite possible and achievable. Genetic research points us in this direction. It’s past time to follow

Driving under the influence of ADHD

The University of Virginia wished to test whether ADHD medication helps young adults while facing driving distractions.

Research suggests that ADHD drivers have a greater likelihood of having or causing an accident. Obviously, hallmarks of the ‘disorder’ are inattention, distractibility, and sometimes hyperactivity. So, when their cell phone rings and they answer, bad things tend to happen.

According to Daniel Cox, Ph.D., professor of psychiatry and neurosciences at the University of Virginia Health System, as a group young ADHD drivers are two to four times more likely to have a car accident than non-ADHD drivers. Cox’ research will examine the effects of methylphenidate (MPH), a controlled-release stimulant worn as a patch, on young ADHD drivers facing real-life distractions.

This is rather clever marketing as the research is funded by Shire Pharmaceuticals, the pharmaceutical mega-giant who makes Adderall and the MPH patch. As I’ve stated before, it’s always questionable when a pharmaceutical giant funds a university study on its own medications. In this instance, it will make great marketing if the good Dr. Cox finds that young adults drive better while on meds! But, heck, since stimulant medication has the same effect on non-ADHD people, shouldn’t we all take it prior to driving? Regardless of that fact, if young ADHD people can wear a patch and drive better, that’ll sell millions of dollars worth of medicine!

The study would likely be significantly more impressive if Dr. Cox used unmedicated non-ADHD young adults and medicated non-ADHD young adults as control groups. I’d be more than eager to see those results.

Or maybe, just maybe, ADHD or not, we should put our cell phones away, put out our cigarettes, not eat in the car, put our pet in a pet carrier, and focus on driving. Shouldn’t we demand that of our ADHD teens before placing a stimulant patch on their arms? 

Cognitive Skills Training and ADHD in Children

PRE-SCHOOL PROGRAM SHOWN TO IMPROVE KEY COGNITIVE FUNCTIONS, SELF-CONTROL

The following press release from the University of British Columbia maintains that a research study has demonstrated that cognitive training can improve attentional control, impulse control, and other executive functions.

Furthermore, the study’s authors cite that practice of cognitive skills in early development years may decrease incidence of ADHD. I have insisted that this was possible for nearly a decade.

Complicating this matter is the No Child Left Behind act (“NCLB”). It is my belief that the NCLB has added to the ADHD problem due in part to the program’s rigid adherence to test scores based on a watered down curriculum that forces teachers to teach the test. Subjects are taught quickly requiring rote memorization rather than significant reasoning or logical application. Additionally, teachers seldom have time to individualize curriculum or nurture students with learning disabilities like ADHD. Thus, rather than encouraging cognitive skills and the development of attention, NCLB has helped promote diffused attention while simultaneously discouraging the development of cognitive skills.

NCLB has also decreased recess time, children’s access to the arts like music and drama, and even physical education. Research has clearly demonstrated increased abilities in mathematics and other academic subjects when students are involved in music and the arts.

The press release:

Program Promises Improvement in Academic Achievement for Children of Poor Families

An innovative curriculum for preschoolers may improve academic performance, reduce diagnoses of attention deficient hyperactivity disorder (ADHD), and close the achievement gap between children from poor families and those from wealthier homes, according to research led by a Vancouver neuroscientist who is an expert on the development of the cognitive functions that depend on the prefrontal cortex area of the brain, called executive functions (EFs).

University of British Columbia Psychiatry Prof. Adele Diamond, who is Canada Research Chair in Developmental Cognitive Neuroscience, led the first evaluation of a curriculum called Tools of the Mind (Tools) that focuses on EFs. These functions include resisting distraction, giving a more considered response instead of your first impulse, working with information you are holding in mind, and the mental flexibility to think “outside the box.”

The program was developed over the last 12 years by educational psychologists Deborah Leong and Elena Bodrova and has been used in several U.S. states. Its value in improving EFs has not been determined until now.

The study is published in this week’s issue of Science.

“EFs are critical for success in school and life. These skills are rarely taught, but can be, even to preschoolers. It could make a huge difference, especially for disadvantaged children,” says Diamond, who is a member of the Brain Research Centre at UBC Hospital; the Child and Adolescent Psychiatry Dept. at BC Children’s Hospital; the Child & Family Research Institute (CFRI); and the Human Early Learning Partnership (HELP). Her work is also supported by Vancouver Coastal Health Research Institute and BC Mental Health and Addiction Services.

“The recent explosion in diagnoses of ADHD may be partly due to some children never learning to exercise attentional control and self-discipline,” says Diamond.

“Although some children are strongly biologically predisposed to hyperactivity and wouldn’t benefit from training, others may be misdiagnosed because what they actually need are skills in self-regulation.”

Previous research has shown that EFs are stronger predictors of academic performance than IQ, she adds. Children from lower-income families enter school with disproportionately poor EF skills and fall progressively farther behind in school each year – facts which Diamond says are related and correctible.

“Helping at-risk children improve EF skills early might be critical to closing the achievement gap and reducing societal inequalities. We showed EFs can be improved in preschoolers without fancy equipment and by regular teachers in regular public school classrooms.”

Most interventions target consequences of poor self-control rather than seeking prevention at an early age, as does Tools. “Early intervention – heading off problems before they develop – costs far less and achieves far better results than trying to correct problems once they have developed,” Diamond says.

“If throughout the school-day EFs are supported and progressively challenged, benefits generalize and transfer to new activities. Daily EF ‘exercise’ appears to enhance and accelerate brain development much as physical exercise improves our bodies,” she adds.

The research team, which includes investigators from the National Institute for Early Education Research at Rutgers University in New Jersey, evaluated 147 five-year-olds in a low-income, urban U.S. school district. Researchers compared Tools with a balanced literacy curriculum (dBL) that covered the same academic content as Tools but without a focus on EF.

Both programs were new, instituted at the same time and used identical resources. Children and teachers in Tools and dBL were randomly assigned and teachers had equivalent levels of education and teaching experience. The children in both curricula were from the same neighborhood and ethnic group, and from families with very similar levels of income and parental education. Children received either Tools or dBL for one to two years.

Evaluation involved two computerized tests that measured EF. These tasks were different from anything any of the children had done before. Better performance by children in Tools shows that they were able to generalize and transfer their EF skills to new situations.

Tools encourages out-loud self-instruction and dramatic play. “Preschool teachers are under pressure to limit play and spend more time on instruction but social pretend play may be more critical to academic success,” says Diamond.

Neurofeedback, ADHD and Medication

In his Attention Research Update, September 2007, David Rabiner, Ph.D. Senior Research Scientist, Duke University, entitled his article, How Strong is the Research Support for Neurofeedback Treatment? The report is rather perfunctory and the staid course he’s followed for years. A fresh, candid review must be performed regarding research on multi-modal treatments, neurofeedback, and medication.

Therefore, my intent here is to examine multi-modal treatments, neurofeedback, medication, their accompanying controversy and myth, and research support. I’m certain you’ll find this examination both enlightening and substantially different perceptively.

I will use some of Dr. Rabiner’s statements and also attempt to make sense of the misinformation that is propagated intentionally or unintentionally through CHADD (Children and Adults with Attention Deficit /Hyperactivity Disorder).

For the purpose of full disclosure when writing this entry:

Play Attention

I should disclose that I developed Play Attention, a device that monitors brain activity. It is used educationally to teach cognitive skills, improve attention, and shape behavior. It is not clinical neurofeedback. To be candid, I’m not a proponent of clinical neurofeedback for reasons I’ll describe below.

Dr. David Rabiner

Furthermore, it should also be disclosed that the Dr. Rabiner’s newsletter is funded by CogMed, a group that sells memory games to address ADHD, and Shire pharmaceuticals, the makers of Adderall and other ADHD medications.

Play Attention has paid Dr. Rabiner in the past to advertise in his newsletter. Dr. Rabiner also sat on the advisory board for Play Attention for several years. Play Attention can no longer advertise in Dr. Rabiner’s newsletter due to his contractual obligations with CogMed. CogMed will no longer allow Dr. Rabiner to sit on Play Attention’s advisory board either.

CHADD & Neurofeedback

CHADD is listed as a nonprofit organization, but still receives significant financial support from the pharmaceutical industry. Historically, it has done little else other than offer tips and strategies and support the use of medicine as a primary treatment.

According to Dr. Rabiner’s newsletter, CHADD’s stance on neurofeedback is summarized in their fact sheet on alternative and complementary interventions, which includes the following statement about neurofeedback:

It is important to emphasize, however, that although several studies of neurofeedback have yielded promising results, this treatment has not yet been tested in the rigorous manner that is required to make a clear conclusion about its effectiveness for AD/HD. The aforementioned studies can not be considered to have produced persuasive scientific evidence concerning the effectiveness of EEG biofeedback for ADHD.”

Well, if we hold EEG biofeedback (neurofeedback) to this “rigorous manner that is required to make a clear conclusion about its effectiveness for AD/HD,” it is only fair to hold every intervention including medication and multi-modal interventions to it as well.

Quite frankly, you’ll be surprised that they do not live up to this standard either. The actual research about medication is really no stronger than that for neurofeedback. It seems we have double talk here by an organization that receives funding from the pharmaceutical industry. Perhaps, given the benefit of the doubt, they just aren’t aware of it.

ADHD Medication Research
While it received little press in 2005, the Drug Effectiveness Review Project, based at Oregon State University released a 731-page report which thoroughly analyzed 2,287 studies – virtually every investigation ever done on ADHD drugs anywhere in the world – to reach its conclusions. To date, it is the most thorough and comprehensive evaluation of all research performed on ADHD drugs.

The American Association of Retired Persons (AARP) and Consumers Union, the publisher of Consumer Reports report the data to their respective audiences. Fourteen states other than Oregon are the principal financiers the Drug Effectiveness Review Project.

The prestigious Oregon Evidence-based Practice Center, Oregon Health & Science University Drug Effectiveness Review Project’s primary purpose is to provide consumers and state insurance plans trustworthy information about pharmaceuticals. The Drug Effectiveness Review Project’s physicians and pharmacists don’t just analyze ADHD medications, so this was not an attempt to subvert or smear that industry. They analyze virtually every study on a given class of pharmaceuticals to determine the best drugs in that class and present their findings to the public and insurance industry. The Project examined 27 drugs which included Adderall, Concerta, Cylert, Focalin, Provigil, Ritalin, Strattera, and others.

In its analysis of published and unpublished research data produced by six prominent ADHD medication producers, the group found that 2,107 studies were unreliable and were subsequently rejected. Now, this is telling in itself. Finding 2,107 funded yet critically poor or fundamentally flawed studies performed by universities and the pharmaceutical industry itself speaks volumes to the nature of that research and those people responsible for it.

The Project began its review of the remaining 180 studies which demonstrated good controls and methods. Its conclusions regarding ADHD medication were quite astounding.

Here, bulleted, are some incredible results with comments:

• “No evidence on long-term safety of drugs used to treat ADHD in young children” or adolescents. Now, if you ask any physician, or the pharmaceutical industry, they will tell you the drugs are completely safe for long-term use based on research. That research doesn’t exist.

• The research providing any evidence of safety is of “poor quality.” This includes research regarding the possibility that some ADHD drugs could cause heart or liver conditions, tics, or stunt growth.

• “Good quality evidence … is lacking” that ADHD drugs demonstrate improvement in “global academic performance, consequences of risky behaviors, social achievements,” and other measures. The common perception is that ADHD drugs do improve academic performance and social skills. Many drug makers use ads depicting this. However, evidence for long-term improvement in academics, social skills, or behavior is virtually non-existent.

• Drug makers have found that they can expand their market by inducing adults into the ADHD experience. However, the Project found that evidence “is not compelling” demonstrating that ADHD drugs actually help adults, nor is there evidence that one drug “is more tolerable than another.”

Furthermore, the Project found that the U.S. Food and Drug Administration doesn’t require pharmaceutical manufacturers to compare newly developed medications with medications currently on the shelf. Most companies simply use a placebo or sugar pill given instead of their medication as a control. Therefore the Project found that “good quality” studies are lacking that pit one drug against another to provide evidence of effectiveness. It also could not find comparative data which might help determine which ADHD medications are less likely to produce detrimental side effects like heart and liver problems, depression, decreased appetite, tics, or seizures.

The Project could not find research that clearly provided an understanding of way that ADHD drugs work. It is not well understood for most ADHD drugs.

Even the research on ADHD performed by the respected Dr. Russell Barkley, a critic of neurofeedback studies, ranked only “fair” in the Project’s analysis of research and he’s had significant funding from the pharmaceutical industry, federal government, and universities. Noting that he’s cited most neurofeedback research as lacking, wouldn’t we expect at least a “good” or even a “superior” on his report card?

So, if one chooses ADHD medication, how does one know which drug is safer? Works better? Has fewer side effects? The research isn’t there, so we don’t know. In light of this, the Project suggested that one may do just as well on methylphenidate (generic Ritalin) which is far less expensive than newer options such as Concerta or Adderall. Incidentally, when the Project reviewed research on Concerta, it concluded that Concerta “did not show overall difference in outcomes” compared to generic good old cheap generic methylphenidate. Is Adderall any better? The Project found evidence to be “lacking.”

Do ADHD drugs provide long-term improvement for academic performance? Social interaction? Better behavior? The research just isn’t there.

The Project made clear that its findings do not mean ADHD drugs are unsafe. They may be safe and sometimes useful, but the Project found scientific proof is lacking.

While I’m not a clinical neurofeedback proponent, I think it’s clear that if pundits like Dr. Rabiner and organizations like CHADD are going to talk about good research, then let’s level the playing field and have the same requirements for everyone.

Standards of Research, Dr. Rabiner, & CHADD

Let’s go back to CHADD for a moment and its warnings about neurofeedback.

“Controlled randomized trials are required before conclusions can be reached. Until then, buyers should beware of the limitations in the published science. Parents are advised to proceed cautiously as it can be expensive – a typical course of neurofeedback treatment may require 40 or more sessions – and because other AD/HD treatments (i.e., multi-modal treatment) currently enjoy substantially greater research support.

Now, let’s examine the 3-Year Follow-up of the NIMH MTA (multi-modal treatment) Study. CHADD states studies such as this most recent one and most thorough one “enjoy substantially greater research support.” :

According to Dr. Rabiner, neurofeedback studies, while often producing good results, often lack random assignment. Here’s what he states in his current newsletter:

    Random Assignment

    Imagine that you are testing a new medication treatment for ADHD with 50 children who have been carefully diagnosed. In a random assignment study, whether each child is assigned to the treatment or control condition is determined by chance – you could flip a coin and give the medicine to the ‘heads’ and nothing to the ‘tails’. This insures that any differences that might exist between children who get the medication and those who don’t are purely chance differences. At the end of the study, if those who received the medicine are doing better, you could feel confident that this is probably due to the medicine itself, and not to differences that may have been there before the treatment even started.

    What if you didn’t use random assignment, but let each child’s parents choose whether their child is in the treatment or control group? In this case, it is possible that children in the 2 groups differed in important ways before the treatment began. If children who received the medication were doing better at the end of the study, it might be because of differences that were there to start with.

    For example, parents who chose the medicine might be more willing to pursue other ways to help their child than those who didn’t. The fact that children who received the medication were doing better at the end of the study might thus have nothing to do with the medicine itself, but reflect other things their parents were doing to help them. No matter how hard you might try to rule out these other possible explanations – and I’m sure you can think of many others – you could never do this with certainty. Thus, I might reasonably doubt that your new medication is really effective.

National Institutes of Mental Health Multi-Modal Treatment Study

But if Dr. Rabiner is correct that research without random assignment is ambiguous, possibly not valid, then let’s try to evaluate data from the 3-Year Follow-up of the NIMH MTA (Multi-Modal Treatment) Study. Let’s look at the researchers said about the 14th month:

    Indeed, once the delivery of randomly assigned treatments by MTA staff stopped at 14 months, the MTA became an observational study in which subjects and families were free to choose their own treatment but in the context of availability and barriers to care existing in their communities.

So what are we to gain from the long-term evaluation done in the MTA study? Does it enjoy substantially greater research support? According to Dr. Rabiner’s standards, not if it became an observational study.

CHADD also warns that neurofeedback is expensive. How expensive is it compared to ongoing medication for a lifetime? We’ll that’s relative isn’t it? How expensive is medication to a single mom with no insurance? Heck, to any parent with or without insurance? To grandparents raising their grandchild in mom’s absence? And by taking medication, which is expensive (Concerta, AdderallXR), etc, are we guaranteed anything more than what neurofeedback might offer? According to available research, No. CHADD’s arguments lack substance but have been their common response for a long time. I am asking that this nonsense ends.

Neurofeedback

Back to neurofeedback…The primary purpose of neurofeedback is to alter brainwave patterns that are presented in real-time feedback to clients. Clients [Rabiner] “…are trained to alter their brainwave activity and taught to alter their typical EEG pattern to one that is consistent with a focused and attentive state. According to neurofeedback proponents, when this occurs, improved attention and reduced hyperactive/impulsive behavior will result.”

Thus, the fundamental premise behind neurofeedback is that brainwaves are dysregulated, especially in certain areas of the brain, and training can regulate them. Furthermore, it is proposed that this regulation improves attention and behaviors. I find this to be rather facile. Neurofeedback’s premise is surprisingly similar to medication in essence; fix these brainwaves and the person is fixed whereas proponents of drug intervention insist that if one takes a pill ADHD is fixed! Unfortunately, neither of these therapies adequately fully addresses core issues of ADHD. Neither medication or neurofeedback, by themselves teach the skills one needs to survive and thrive in the workplace or classroom. Skills like organization, improved memory, discriminatory processing, auditory processing, time-on-task, etc. are not trained through either of these interventions. The only way to attain them is to train and learn them.

I’m not saying that neurofeedback doesn’t work. It’s been field tested as has been medication for years. Could it be a worthwhile tool to be used in a multi-modal plan? Yes. Again, let’s level the playing field.

Current Neuroscience & Neuroplasticity vs. Current ADHD Interventions

The reality about neurobehavioral problems is that they exist in a context, i.e. they exist because of the brain and because of that brain’s environment. The brain is directly affected by its environment. The brain is neuroplastic; it will and does adapt according to the stimulation it receives. That is conclusive fact. No doubt about it. So, if we are speaking about a human being, then attention problems are not just brain based. They may take root there, but they are also directly related to and affected by one’s environment. Therefore, appropriate environmental factors play a great role in the treatment of ADHD including behavior shaping, consistent reward/consequences, structure, etc.

The fact that our current system doesn’t address this fact is where we fall far short of correctly treating ADHD.

Let’s say that little Jimmy demonstrates some fidgeting and inattention at school. His teacher writes a note home telling Jimmy’s parents she suspects Jimmy may have ADHD. Jimmy’s parents take heed and bring him to the pediatrician where Jimmy gets a prescription for medication within 20 minutes. This is the norm.

What’s sorely missing is where Jimmy’s parents or Jimmy’s pediatrician write a note back asking to speak to the teacher to develop a plan of action regarding Jimmy’s behavior before beginning medication. This should be our standard practice regarding ADHD. We need to change the way we view ADHD and the way we address ADHD according to current neuroscience, not how we addressed it in 1980.

Unfortunately, most pediatricians or general practitioners are quite overwhelmed and not well equipped educationally to provide a full battery of tests taking up to four or five hours for an accurate diagnosis. So, a reverse diagnosis is made; the MD writes the prescription for medication and if it works, it was ADHD!

The problem is that stimulant medication works for everyone. If we have two groups of children, one group diagnosed with ADHD and one group of average children, both given boring tasks, both medicated, who will do better on the boring tasks? The answer is: Both! Medication is a shotgun approach that teaches nothing. Virtually no research demonstrates long-term efficacy in social improvement, academic improvement, or behavioral improvement.

Attention is a skill like any other skill. It can be considered a cognitive skill that is measured by behavioral or performance analysis. Should strategies, known to work to improve performance on ADHD students be attempted before medication or neurofeedback? Yes. Resoundingly yes! Should Jimmy’s parents adopt a structured, consistent schedule at home? Yes. Should Jimmy’s parents develop a behavioral plan for school and home working together with Jimmy’s teacher? Yes. Should all of this be employed before neurofeedback and medication? Yes. Could it be employed while using either medication or neurofeedback? Yes. Is it far less expensive than these other interventions? Yes.

Why don’t we do this first then? While a variety of factors relate to the answer, one of the most significant ones is: It is easier to take a pill or to ask someone else to solve your problem than it is to do the work to solve it yourself. Granted, many parents are not trained to work with ADHD children, but they can learn and need to – it’s part of being a parent.

I’ll quote the respected psychologist, Dr. Abraham Maslow –

If the only tool you have is a hammer, you tend to see every problem as a nail.

Here’s how this quote relates to our current dilemma: Many parents rely on their Doctor’s opinion alone believing the physician is almost all knowing. Doctors, pediatricians included, are sparsely trained to instruct parents or educators on how to facilitate a multi-modal management plan. Instead, as they are instructed from medical school and because medicals schools rely heavily on pharmaceutical money, they are given the only answer: drugs. It is only natural that parents believe this. Unfortunately, neither the medical industry, pundits, or CHADD are familiar with research regarding medication or either choose to ignore it.

Neurofeedback Controversy

Back to Dr. Rabiner’s newsletter, this segment entitled, Controversy Surrounding Neurofeedback Research.

Neurofeedback treatment for ADHD has been a source of substantial controversy in the field for many years and remains so today. Although there are a number of published studies in which positive results have been reported, many prominent ADHD researchers feel that given significant limitations to the design and implementation of these studies, neurofeedback should be considered a promising, but unproven treatment.

I think it’s quite reasonable to say that the ‘controversy’ surrounding neurofeedback is constantly stirred up by articles such as Dr. Rabiner’s. He also says that neurofeedback studies sometimes suffer from smaller populations, etc. It does make good press, but given significant limitations to the design and implementation of studies on multi-modal treatments and pharmaceuticals, they should all be considered promising, but unproven treatments. Neurofeedback research seems to suffer the same dilemma as that of multi-modal and pharmaceutical interventions – all could be far stronger. All have considerable weaknesses. All have some strengths because they’ve been field tested for many years. So, either they are all controversial, or none of them is controversial. It’s far past time to stop double talking.

Summary

Neither medication nor neurofeedback are solutions unto themselves.

Without hidden agendas or profit motives they are on the same playing field. Now, let’s play fair and develop strategies based on our knowledge of the ADHD problem. It’s in the best interest of our children and their outcomes to find workable, manageable solutions.

Obviously, no one intervention is best, proven, or more reliable even if marketing people would like to make it seem so. It takes a whole village to raise a child. It takes a group of interventions to raise an ADHD child. Let’s find the best interventions, based on honest available research, use them in concert, and see if it works. And understand this caveat clearly, just because research, no matter how high a grade it’s given, demonstrates efficacy, it doesn’t mean that it will work successfully for you or your child. That’s just because we’re human. We learn differently, respond differently, and are wired differently based on our years of exposure to the world and our genetic makeup. That’s not theory. That’s fact.

Given that no intervention is sufficient by itself, it will always be a matter of trail and error to determine what course of actions will succeed for the long-term. Even though we desire or wish it, none are guaranteed, but that’s life, isn’t it?

Can we map attention, memory and language links in the human brain?

A University of Arizona scientist, Thomas Christensen applied for a $1 million career development award from the National Institute of Deafness and Other Communication Disorders. The grant was awarded in April and funds Christensen to conduct a pioneering 5-year study on the roles that attention and memory play when the human brain hears and processes spoken language.

“This is the chance to study the ultimate form of animal communication – language,” said Thomas A. Christensen of UA’s department of speech, language and hearing sciences (SLHS). “Humans have evolved a very sophisticated symbolic form of communication. Language affects how we think, what we believe, how we interact with each other. I’d even go so far as to say that our future as a species depends on understanding how we communicate. But very little is known about what’s going on in the brain when we’re having a simple conversation.”

Christensen will use UA’s magnetic resonance imaging (MRI) facilities to map the areas and networks within the brain linked to language, attention and memory. While this has been done before, Christensen’s techniques are slightly different – inside the scanner volunteers will perform simple language discrimination tasks.

“You read in the text books is that if you’re right handed, then language is localized to the left hemisphere of your brain,” Christensen said. “I found out right away – that’s just not true. Analyzing a human voice also involves the right hemisphere and even parts of the cerebellum.” Nothing new here either, unfortunately.

It’s interesting that Christensen “found out right away [that language is localized to the left brain hemisphere]– that’s just not true,” because as long as 30 years ago, examinations of patients who had their corpus callosums split by accident or by surgery demonstrated language wasn’t localized in the left hemisphere of the brain.

“These MRI images destroy the myth that you’re only using about 10 percent of your brain for any particular task,” Christensen said. “The crux of this grant is to learn more about the language, attention and memory centers in the brain, and also about the complex interactions between them.”

The MRI scanner reveals the brain’s activity. As UA’s press release states, the MRI scanner shows networks that scientists didn’t suspect were involved when the brain listens.

“We’re getting a snapshot of what that activity is across the population. What’s so striking is how clearly we see that certain areas of the brain are strongly engaged in attentional control while other areas are not. As we scan more volunteers, we’re definitely beginning to see a pattern here.”

“ADHD (Attention Deficit Hyperactivity Disorder) is probably one of the most over-diagnosed disorders of our time,” Christensen said. “The reason for that, I think, is that we really don’t know very much about the biological basis of this syndrome. There’s a lot of research on it, but there’s still a lot of disagreement about what the root cause is, and about whether drugs like Ritalin that are being prescribed to children as young as 2 years old are doing any good, and if we have any business exposing our children to drugs at such a very early age,” he added.

ata that show the connections among areas of the brain that are strongly engaged in language tasks, he plans to collaborate with computer modeling experts. “We could develop a mathematical model that would allow us to generate hypotheses about what we expect if we deliver a certain type of stimulus. We’d see what effect it would produce in our model.”

Simulating brain activity in the mathematical model “would take the whole question of language processing beyond ‘blobology’ – where you’re just looking at blobs of activation in the brain. That’s what I hope to do,” Christensen said.

So in answer to my title question, Can we map attention, memory and language links in the human brain? No. However, we do need good research in this area. MRI does demonstrate activation in areas of the brain. Christensen will have to determine the relationships between the active networks – that’s more art than science currently since current MRI and fMRI don’t depict anything more than activation. The basic tangent Christensen is examining will likely move ‘blobology’ forward a little, but we are still a long way from understanding the brain – the most complicated piece of matter that we know of. Quite a paradox, isn’t it? – the most complicated piece of matter that we know of, the brain, which is essentially a super computer, cannot understand itself. Yet.
