Martijn’s dissertation far exceeds the quantity of work seen in PhD dissertations, covering a breadth and depth generally not seen from any less qualified than a full professor. His review of the literature, providing of a meta-analysis of the use of NF in ADHD lays the basis for the current level of acceptance NF in ADHD has achieved within the Neurosciences. His work also includes the prediction of medication response in ADHD and Depression, as well as the application of rTMS to depression, and an investigation into personalizing the rTMS stimulation paradigm. Seldom is such a breadth or depth of work seen in a PhD dissertation, as it generally would be too much work to finalize such an endeavor.

Martijn went back into the historic EEG literature far enough to gain insight into some of the reductionistic errors that the early days of qEEG created in our ability to understand the very nature of some of the pathologies we are currently studying. His dissertation disentangles the presence of slowed alpha from true theta rhythm, and also tests prospectively the EEG Phenotype model, integrating it with the European Vigilance model, and postulating biomarkers that predict clinical approaches.

It is easy to see why Martijn has gained such prominence in the neuromodulation field at such a young age (compared to me he is very young… but so is almost everyone else!)

First Direct Evidence of Neuroplastic Changes Following Brainwave Training

ScienceDaily (Mar. 12, 2010) — Significant changes in brain plasticity have been observed following alpha brainwave training.

A pioneering collaboration between two laboratories from the University of London has provided the first evidence of neuroplastic changes occurring directly after natural brainwave training. Researchers from Goldsmiths and the Institute of Neurology have demonstrated that half an hour of voluntary control of brain rhythms is sufficient to induce a lasting shift in cortical excitability and intracortical function.

Remarkably, these after-effects are comparable in magnitude to those observed following interventions with artificial forms of brain stimulation involving magnetic or electrical pulses. The novel finding may have important implications for future non-pharmacological therapies of the brain and calls for a serious re-examination and stronger backing of research on neurofeedback, a technique which may be promising tool to modulate cerebral plasticity in a safe, painless, and natural way.

Neurotherapy using slow cortical potentials also shows promise in the treatment of epilepsy (Kotchoubey et al., 2001; Birbaumer et al., 1981; Sterman, 2000). Neurotherapy has also been used for ADD/ADHD (Monastra, Monastra, & George, 2002) depression (Rosenfeld, 1997), anxiety (Vanathy, Sharma, & Kumar, 1998), fibromyalgia (Donaldson, 2002), and for cognitive enhancement (Budzynski, 2000; Klimesch, et al.). Commonly reported success rates of 60 to 90% are reported  (Wright & Gunkelman, 1998).

Neurofeedback is an emerging neuroscience based clinical application based on the general principles of biofeedback or cybernetics. The Neurofeedback process involves training and learning self regulation of brain activity. Understanding the underlying principles of this process allows the therapist to provide referrals or treatment to their clients with some added understanding, and provides clients with  a framework for understanding the neurofeedback process. The following short paper will provide a quick review of the brain’s function, and the underlying process involved in neurofeedback, a technique  that will allow the client to better regulate and operate their brain.

The brain controls its own blood supply through the dilation and constriction of the blood vessels, and the blood flow is directed to areas that are more active through this self-regulation. The blood supply’s flow, along with the utilization of the oxygen and glucose the blood carries is measured as “perfusion,” a measure that is clearly seen in some of the modern imaging techniques, such as Positron Emission  Tomography (PET) and SPECT technology. Though these techniques are invasive, requiring the injection of small amounts of very short half-life radioactive materials, they do give good resolution of the perfusion due to the emission of the positrons, which are emitted from where the brain utilizes the oxygen and burns the glucose carried by the blood flow.

A research project performed at UCLA’s Neuropsychiatric Institute (Cook, O’Hara, Uijtdehaage, Mandelkern, & Leuchter, 1998) showed that the brain’s electrical activity, or electroencephalogram (EEG), had specific correlates of the brain’s perfusion. This is useful in that the EEG is capable of showing when the perfusion is low, such as  seen frontally in ADD/ADHD. In these situations, the EEG shows a resting or idling rhythm of alpha (8–13 Hz) and/or theta (4–7 Hz), frequency patterns in the EEG that have rhythmic waveforms.
(For a general review of electroencephalography see Niedermeyer & Lopes Da Silva, 1999).

In ADD/ADHD a study of over 400 participants using a neurometric approach (see Prichep & John, 1992; Prichep et al., 1993) showed that there were generally findings of excess alpha and/or theta in the frontal lobes (Chabot & Serfontein, 1996), which corresponded to the frontal hypoperfusion seen in ADD/ADHD with the PET or SPECT perfusion studies. The frontal lobes are executive areas in the  brain, which control attention, emotions (affect) and impulsivity, as well as regulate (inhibit) the motor areas of the brain. The Chabot study (1996) also showed that the EEG could be used to differentiate those with ADD/ADHD from normal clients, as well as differentiating ADD/ADHD from those participants with a learning disability (LD). The LD population was shown to have a slower pattern, with excess activity in the delta frequencies (1–3.5Hz) over the central and parietal lobes (posteriorly at the crown of the head). These areas are responsible for integrating raw sensory stimuli into perceptually interpretable activity.

More recently, a comparison of children and adults seen in a single neurofeedback practice specializing in ADD/ADHD was performed (Gurnee, 2000). This study showed that unlike the children’s study, which showed theta to be the dominant pattern, the adults had an alpha dominance, likely due to maturational changes that have increased the frequencies. In the children the excess theta group is over 50% of the cases, with the adult group showing excess theta to only comprise about 25% of the incidence.

The qEEG data may also be used to select specific medications if a pharmacotherapeutic approach is preferred. The qEEG pattern of frontal theta responds better to stimulants such as methylphenidate (Ritalin), whereas the frontal alpha type responds better to antidepressants. If a specific statistical measure called ‘coherence’ is deviant (too high or too low), the participant may require an anticonvulsant (Suffin & Emory, 1995). These patterns also may coexist such that an individual may require two or more types of medication.

Physicians generally use behavioral indicators in choosing psychoactive medication. However, it was clear from the work of Suffin and Emory that neurophysiological profiles can be used to guide prescription, even in populations of patients with similar behavioral disturbance (e.g., attentional or affective disorders as defined by DSM). Most physicians generally find the proper medication the old fashioned way . . . by trial and error. The “best guess” medication selection method requires more doctor office visits, medication trials, and has the possibility of significant side effects. All this is generally avoided with the more objective qEEG based method, which is based on the person’s physiology, not the behavior. It is not difficult to see why this is the case. The medication treats the physiology, hoping to affect the behavior. The measurement of the physiological indicators should logically be more related to the proper medication choice, since this is what is actually being treated.

The stimulant medications typically decrease appetite, with weight loss commonly noted, as are sleep problems. Long-term use of stimulants have been known to cause teeth grinding (Bruxism), cardiac rhythm changes, blood pressure increases, weight loss, changes in sleep patterns, anxiety/nervousness and even “psychotic” symptoms (such as hearing voices or other sensory hallucinations). There are also those with medical contraindications for stimulant use, such as heart problems, gastro-intestinal and blood pressure problems and other more rare complications that preclude prescribing them. In these individuals, as in those with complications from taking the medications, the presence of an alternative treatment is essential for proper behavioral adjustment and scholastic achievement. For those individuals uncomfortable with using potent medications, or those with adverse side effects, it is fortunate that a non-medication intervention is available.

The choice of medicating the client requires continued treatment, as it is merely a temporary change, due to the drug’s effects. Neurotherapy is a treatment, which changes the way the brain works, and once the skill is learned, (unlike medication) it appears to be persistent. Follow-up studies show long-term change in the brain’s function following neurotherapy (Monastra, 2003). Both of these methods (medication and neurotherapy) improve the client’s attentional and behavioral states. The choice of which method to use is merely a personal choice. Medications, when used long term, may end up being more expensive than Neurotherapy. Neurotherapy has less likelihood of having side effects than does the medication, but it takes a number of training sessions before the effect is noted and becomes more persistent.

It is no surprise that the brain can learn, but what may surprise some is that the brain changes structurally when it learns. This morphologic change is microscopic, the forming and reinforcing of small connections between a part of a neuron, called “dendrite,” but it is a structural change, nevertheless. This highly changeable connective nature is referred to as “neural plasticity,” based on the original definition of plastic, not as a substance, but as a descriptor of the malleability or change—ability of materials or structures.

The brain has a method of developing and expanding the pathways that are used, and “pruning” the connections that aren’t utilized. This process is most dramatic early in life, but continues throughout life. We are born with about twice as many neurons as are present when we become young adults. The pathways that are more consistently utilized are protected from the pruning process through a mechanism still unknown to science, though the fact of the change is irrefutable.

Another time when this process of plasticity is evident is following damage, such as head injury, or disuse of an area, due to “deafferentation,” such as when hearing is lost. In these situations the surrounding functions may take over an area not utilized, occasionally causing some subjective changes, which may be uncomfortable. One example of this is tinnitus, or ringing in the ears, following loss of hearing; another is “phantom pain” when a limb is severed and is no longer present, but sensations seeming to come from the missing limb are felt. The functions adjacent to these areas in the brain merely intrude into the area and the person misinterprets these new
signals as the older inputs.

These examples are dramatic, but “growththrough-utilization” is the underlying process we want to focus on. This process is how we build additional capacity for the nervous system to do its work. Analogous to exercise building muscle mass, the utilization of the brain builds the mass of the brain’s dendritic connections.

Certain intense negative experiences may change the body’s chemistry, increasing the stress hormone released from the adrenal cortex of the kidneys. This chemical, cortisol, is a healthy response to stress, though with chronic or overly intense stressors, the cortisol has deleterious effects on the brain, specifically attacking a temporal lobe structure, the hippocampus, which has immune receptors. This structure has important non-immune system functions as a memory comparator, required for both comprehension and recall. The implication for this latter process where stress deteriorates the brain’s ability to comprehend and recall has large implications for education. A person with a stressful existence may never reach his or her true potential due to the damaging effects of the stress hormones. If the stress was experienced during pregnancy from the mother’s hormonal balance, the newborn will have a disproportionately intense reaction to stress, causing inordinately large amounts of strain (and thus more cortisol) and ultimately more extensive deterioration of the brain’s capacity.

The ability to teach a new response to the situational stressors can change the life course for these individuals, creating a much more favorable outcome. The operant conditioning technique, Neurotherapy, mentioned earlier is one such method of intervention. Similarly to the stress response, there is a relaxation response, which can be trained to counteract these deleterious effects.

The brain’s electrical patterns are a form of behavior, which is subject to behavior modification through “operant conditioning,” a fact discovered in research done in the late 1960s by Dr Barry Sterman, now a professor emeritus at UCLA. The operant conditioning of the EEG was first demonstrated in cats, where placebo effects are assumed to be absent. Sterman’s original work with animals was replicated in humans starting in the 1970s (Sterman, 2000).

Recording and analysis of EEG has been shown to yield reliable results (Fein, Galin, Yingling, Johnstone, & Nelson, 1984). Further, those studies done with control groups have shown the neurotherapy technique to be a robust and valid intervention. Many more studies are of a case series variety, without control groups. Though this latter category is not held in high regard, perhaps this is changing. A recent issue of the New England Journal of Medicine reviews of research design have cast doubt on the need for placebo-controlled designs. Their review has shown that when there is a preponderance of case series reports, the concordance between those results and those of the “gold standard” (double blind placebo-controlled studies) was very high. Many in the field are now arguing against doing a double blind study due to the lack of proper humane treatment of those in the control group (receiving no treatment), an approach which is also now considered unethical by the World Health Organization when known treatments exist. Interestingly, recent work with placebo effect has elucidated brain mechanisms underlying placebo response that were different than those mediating medication response (Leuchter, Cook, Morgan, Witte, & Abrams, 2002).

With the neurotherapy approach, the brain frequencies that are in excess are reduced, and those with a deficit are increased. The technique uses the EEG, amplified from the minute voltages and hooked up with special instruments to control a computer game. The person’s EEG is the “joystick” they use to operate the game. Over a series of sessions the person learns to use the EEG to control the game. The clinician slowly adjusts criteria for reward presented to the individual, and thereby “shapes” the behavior of the participant’s brain into a more normal pattern.

The neurotherapy technique requires time to learn, and varies depending on the initial condition the individual starts with. In general, the more severe the starting condition, the more learning has to occur to correct the state. Simple relaxation may take as few as 10 sessions to learn; although with more severe cases, a longer training course may be needed, such as with generalized anxiety disorder, or panic attacks. The important point is that the learning is internalized so that the benefit of the training persists, and does not require on-going training. This is unlike the use of medications where symptoms typically reappear after discontinuing medication.

The learning curve for EEG has been described in research done at Langley Porter Neuropsychiatric Institute, at the University of California, San Francisco. The research showed that the curve is a fifth-order curve, which contains an initial increase, followed by a dip, a second increase, followed by the exponential increase at the end of the training (Hardt, 1975). This corresponds to the subjective states reported in some individuals. They are initially presented in a slightly anxious state, which gets better when they habituate to the training situation, corresponding to the initial increase in the curve. The individuals then report that they “try hard to relax,” a counterproductive attempt, which corresponds to the dip. They give up trying hard (active volitional attempts), corresponding to the second increase, which is then followed by the learning of the passive volitional state, which is the final exponential increase.

In some cases, the individuals may need more peripheral forms of biofeedback-based intervention, such as muscle relaxation or training of temperature or the electrodermal responses. These will depend upon whether their individual response profile shows their stress in these areas as well. The peripheral training often requires less training time, though the source of the difficulty is universally central, as these modalities are all under the control of the central nervous system. Training peripherally may be all that is required in more mild cases, but in many individuals, the central training is the only method that will have a persistent result. In our clinical experience with these more severe cases there may be symptom substitution without the central intervention. In cases with mild stress, the peripheral intervention is often a complete intervention, though when additional complaints such as attentional problems, depression, or hyperactivity are noted, the central intervention is usually the first choice, to minimize the total number of sessions, by getting directly to the common source
of the problem.

Prior to starting work with an individual, and in order to design an appropriate operant conditioning intervention, their existent brain function must be known. Optimally, this would entail a full recording of their EEG, with quantitative analysis and comparison of the individual’s brain activity to an age matched database. These databases are commercially available from a number of sources, and are described in a recent Journal of Neurotherapy special edition (Vol. 7, No. 3 and 4, 2003). Following such a comparison, areas that deviate from normal may be identified, as well as the direction of the deviation from normal. This shows whether an excess or a deficit of any frequency pattern exists, as well as the location of the deviation. Specific individualized patterns of results are used to guide intervention with neurotherapy.

Following this evaluation, an appropriately customized operant training may be designed which optimizes the training time by focusing on the areas of deviation. The training will take time, with 30 to 40 sessions being quite common before a permanent result is established, and even more are required for more severe or complex cases such as Asperger’s/Autism (Thompson & Thompson, 2003). There are commonly reported behavioral changes long before this end point of training is reached, with the early signs of change showing themselves at 5–10 sessions for most individuals, though some have strong changes even after their initial session. It is also common for an individual to not notice the change, as they are occasionally not self-aware, though the changes are easily seen in objective testing and reported by those observing the individual’s behavior.

Commonly reported success rates of 60 to 80% are seen in the scientific literature, with up to 90% reported in qEEG based intervention (Wright and Gunkelman, 1998). Using strict criteria (total remission of complaint) the percentage range from 50 to 60%, with those reporting positive results, though with less stringent measurements of success, such as “feeling like you got a positive benefit,” ranging in the 80 to 90% rate.

Many therapists are not aware of neurofeedback as an application of operant conditioning, being familiar with more easily observable behavioral operant training than the operant training of “internal states.” The neurofeedback literature is most well accepted in the area of operant training of EEG in epilepsy. Well-controlled studies show that the technique can assist in cases where medication alone was shown to be inadequate at controlling the electrical discharges associated with the epilepsy. A review of this application is published in a special edition of Clinical EEG, in the January 2000 issue (Sterman, 2000). Neurotherapy using slow cortical potentials also shows promise in the treatment of epilepsy (see, Kotchoubey et al., 2001; Birbaumer et al.,1981).

Since the EEG in epileptics can be taught to stop the abnormal discharges, leading to the elimination of the behavioral manifestations of the epilepsy, the neurotherapy technique has also been applied in less severe neurological disorders such as ADD/ADHD (Monastra et al., 2002) depression (Rosenfeld, 1997), anxiety (Vanathy et al., 1998), and fibromyalgia (Donaldson, 2002). Budzynski (2000) used neurofeedback to reverse cognitive decline in an elderly population (see also the work of Klimesch et al. for studies of EEG related to memory performance). For recent reviews of neurobehavioral disorders noted to respond to this emerging technologically based operant training technique see Yucha and Gilbert (2004), and Nelson, (2003).

There are two international professional organizations dedicated to the study of this technology and these applications: the Association of Applied Psychophysiology and Biofeedback (AAPB), and the International Society for Neuronal Regulation (ISNR). Both of these societies have annual conferences and often sponsor additional regional workshops. There are also many state and regional organizations, often affiliated with one of these international organizations. ISNR also has international chapters in other countries. Both organizations have web sites (www.aapb.org and www.isnr.org), and both sponsor a professionally published journal with material focused on Neurofeedback: The Journal of Neurotherapy (ISNR), and Applied Psychophysiology and Biofeedback (AAPB).

Neurofeedback is a treatment where real-time feedback is provided for specific brain activity (most often EEG) in order to learn the brain to suppress or produce specific brain activity. This method was initially discovered for the treatment of Epilepsy and from 1976 investigated further for the treatment of ADHD. This technique has become more popular by clinicians worldwide, and is currently provided for the treatment of several disorders. Critics have often questioned the efficacy of Neurofeedback and whether it can be considered an Evidence Based treatment or not.

In collaboration with researchers from Tübingen University (Germany), Radboud University (Nijmegen, the Netherlands), Brainclinics and EEG Resource Institute a so-called meta-analysis was conducted on all published research about Neurofeedback treatment in ADHD. This meta-analysis included 15 studies and 1194 ADHD patients. Based on this study – which will be published in the July issue of EEG and Clinical Neuroscience – it could be concluded that Neurofeedback can indeed be considered an Evidence-Based treatment for ADHD. The results show that neurofeedback treatment has large and clinically significant effects on Impulsivity and Inattention and a modest improvement of Hyperactivity.

These findings apply to Neurofeedback treatment for ADHD, but do not automatically imply that Neurofeedback can be considered evidence based for any disorder. The efficacy of Neurofeedback has to be assessed separately for each disorder. For example, a meta-analysis of EEG biofeedback in Epilepsy is published in the same issue of EEG and Clinical Neuroscience demonstrating clinical efficacy in the treatment of epilepsy.

Interested clients are advised to make an informed choice regarding Neurofeedback therapists, since there is a large heterogeneity in neurofeedback treatment approaches and clinicians. It is advised to look for psychologists or physicians who are at least a member of a professional organization such as the International Society for  Neurofeedback and Research (ISNR: www.isnr.org) or other professional organizations and who use investigated methods.

Our organization needs to provide information regarding the types of training/treatment that has been proven  over and over to help clients that have severe impediments to their lives.  If you feel similarly and would like to either sign this letter or write your own, it may cause some movement in APA and the Monitor to recognize the services we provide.

Letter to APA regarding qEEG – March 09 2009

James H Bray PhD, President APA

Dear Drs. Bray and Farberman,

Imagine the excitement of seeing “Brain Imaging” on the front of the Monitor for the March 2009 edition.  Finally, the APA is writing about QEEGs (quantitative electroencephalograms) and the types of work that is being done by thousands of psychologists in the neurofeedback world.

No, the first article is “A pacemaker for your brain?” which reviews the effect of deep brain stimulation (DBS) for the treatment of depression.  The second article “From the Research Lab” informed us about implanting electrodes on the surface of the brain to pinpoint where to surgically remove parts of the brain to correct the disorder from which the client was suffering.  The instrument discussed is fMRI. Perhaps I have not been keeping up with the areas of scope of practice for psychologists but this falls under medical procedures and few psychologists can afford an fMRI machine in their private office.  Yes, many psychologists work with fMRI’s in hospital settings, still it is a small number compared to the number of psychologists/neurofeedback therapists in the United States.

It is time the APA and the Monitor recognize the value of the thousands of psychologists around the world and approximately 3000 in the USA who use non invasive imaging techniques and treatments/training to reduce/eliminate epilepsy, traumatic brain injury; depression; ADHD;  and a host of other disorders.  As you probably know, early on, neurofeedback was, studied and researched in psychology laboratories,and is based on the principles of operant conditioning, which is a major area of development and focus for psychologists (beginning with its founder, psychologist B.F. Skinner) Some of the most seminal research in brain imaging and neurofeedback was and is conducted by psychologists ( for example Barry Sterman, Ph.D whose research led to the validity of neurofeedback, Joel Lubar, Ph.D. and Robert Thatcher, Ph.D.)Also early studies by Steven S. Fox, Ph.D. ( Univ. of Iowa, dept of psychology) with his 1967-1971 EEG/EP operant conditioning studies in cats and humans as well as Peter Rosenfeld, Ph.D. and Alan Rudell, Ph.D. who also published rigorous scientific studies on EEG/EP biofeedback in the late 1960s and early 1970s need to be recognized.

Do not be persuaded by the American Neurolog ical Academy’s viewpoint that QEEGs are not valid.  Recently, in a court case in NY State the QEEG was admitted as meeting Daubert criteria. This is one of many in the United States courts that have admitted QEEG’S as part of the defense.   It submitted thousands of studies using QEEG to verify its validity. The criterion used to locate the studies were computerized analysis of QEEG results. Also do not be persuaded that the Neurofeedback training is not valid, especially, when hundreds of studies have shown excellent outcomes.  These studies have been published in numerous journals.

Furthermore, Carl U. Weitman, Phd., F. BCIA-EEG chaired a liaison task force from 1995-97 between APA and AAPB that resulted in the APA practice directorate and APA council recognizing neurofeedback and QEEG as proficiencies within the scope of psychology; applied psychophysiology and biofeedback.  Among the results, state boards aligned their views with those of the practice directorate. In the interim, the practice code  90876 came to be “Psychophysiological Psychotherapy.
Perhaps you could see to having an edition that looks at Brain Imaging that employs the techniques that psychologists use and the training that they employ guided by those images and interpretations which are against normative databases.

Thank you for your kind attention to this letter.

For children with attention deficit/hyperactivity disorder (ADHD), a reduction of inattention, impulsivity and hyperactivity by neurofeedback (NF) has been reported in several studies. But so far, unspecific training effects have not been adequately controlled for and/or studies do not provide sufficient statistical power. To overcome these methodological shortcomings we evaluated the clinical efficacy of neurofeedback in children with ADHD in a multisite randomised controlled study using a computerised attention skills training as a control condition.

Methods: 102 children with ADHD, aged 8 to 12 years, participated in the study. Children performed either 36 sessions of NF training or a computerised attention skills training within two blocks of about four weeks each (randomised group assignment). The combined NF treatment consisted of one block of theta/beta training and one block of slow cortical potential (SCP) training. Pre-training, intermediate and post-training assessment encompassed several behaviour rating scales (e.g., the German ADHD rating scale, FBB-HKS) completed by parents and teachers. Evaluation (‘placebo’) scales were applied to control for parental expectations and satisfaction with the treatment. Results: For parent and teacher ratings, improvements in the NF group were superior to those of the control group. For the parent-rated FBB-HKS total score (primary outcome measure), the effect size was .60. Comparable effects were obtained for the two NF protocols (theta/beta training, SCP training). Parental attitude towards the treatment did not differ between NF and control group. Conclusions: Superiority of the combined NF training indicates clinical efficacy of NF in children with ADHD. Future studies should further address the specificity of effects and how to optimise the benefit of NF as treatment module for ADHD. Keywords: Neurofeedback, attention deficit/hyperactivity disorder (ADHD), slow cortical potentials (SCPs), theta/beta training, randomised controlled trial (RCT), EEG.
