What is neurofeedback?
Electroencephalography (EEG) neurofeedback is a type of biofeedback therapy which measures and records the brain waves. The user receives visual or auditory feedback which help to train the brain to better regulate its activity. Neurofeedback has been used in clinics around the world for decades, and clinical research has shown it to be effective in treating many neurological conditions with lasting results.
Neurofeedback, or EEG biofeedback, is a non-drug treatment which belongs to a group of therapies called biofeedback. Neurofeedback has been used in clinics for decades to successfully treat various conditions, including Autism/ADHD, PTSD, anxiety, traumatic brain injuries, and others.
Neurofeedback is a safe, evidence-based treatment which can control symptoms with little or no side eﬀects. Many research studies have shown it to be as eﬀective as stimulant medications in treating ADD/ADHD. Clients can learn to change their brainwave patterns by playing games and watching videos as part of a training program, usually lasting 30-40 sessions.
Myndlift Neurofeedback training require an EEG headset that is placed on your head. The headset connects with the iPad via Bluetooth. The program allows you to play video game which is controlled by your brainwaves. In the process of playing these games, your brain will learn better self-regulation and improvement in functioning.
What is the evidence behind neurofeedback?
Neurofeedback was first discovered in the 1950’s as a form of operant conditioning, in which the brain changes its activities as result of stimuli, or positive or negative feedback.
Myndlift Neurofeedback is therapist-guided, which means clinicians provide personalized supervision.
Research behind Neurofeedback for ADHD
The impact of neurofeedback on ADHD has been studied the most among all neurofeedback therapies. Many studies have been published over the years, we chose few recent ones to show you:
102 children aged 8-12 with an ADHD diagnosis were randomly assigned in two groups- one group did 36 neurofeedback sessions, the other did 36 sessions of computerized attention skills training game.
Improvements in the neurofeedback group were superior to the control group. The findings indicated that “neurofeedback effects are substantial and of practical importance. Our results confirm findings of previous neurofeedback studies even under strict control conditions.” The researchers concluded the result “indicates clinical efficacy of neurofeedback in children with ADHD”.

130 children diagnosed with ADHD aged 6-18 were randomly assigned into 3 groups – one received neurofeedback, one received medication (methylphenidate), one received both neurofeedback and medication.
The researchers conclude that “NF produced a significant improvement in the core symptoms of ADHD, which was equivalent to the effects produced by MPH (methylphenidate), based on parental reports. This supports the use of NF as an alternative therapy for children and adolescents with ADHD.”

American Academy of Paediatrics rated neurofeedback as a Level 1 “Best Support” Intervention for ADHD. This is highest possible rating and at the same level as medication treatment and behavioural therapy.
104 children were randomly assigned to receive NF (neurofeedback), cognitive training or a control condition. They were also evaluated 6 months post-intervention.
"Neurofeedback participants made more prompt and greater improvements in ADHD symptoms, which were sustained at the 6-month follow-up, than did CT participants or those in the control group. This finding suggests that neurofeedback is a promising attention training treatment for children with ADHD.”

Introduction to Neurotherapy
Neurotherapy is also called Neurofeedback or EEG Biofeedback. In the late 1960's and 1970's we learned that it was possible to recondition and retrain brainwave patterns. Some of this work began with the training of alpha brainwave activity for relaxation, while other work originating at UCLA focused on uncontrolled epilepsy. This training is called Neurotherapy or EEG biofeedback or Neurofeedback. Before discussing this in more detail, let me provide you with some preliminary information about brainwaves. Brainwaves occur at various frequencies. Some are fast and some are quite slow. The classic names of these EEG bands are delta, theta, alpha, and beta. They are measured in cycles per second or hertz (Hz). N
Beta brainwaves (above 13 Hz) are small, faster brainwaves associated with a state of mental, intellectual activity and outwardly focused concentration. This is basically a "bright-eyed, bushy-tailed" state of alertness.
Alpha brainwaves (8-12 Hz.) are slower and larger. They are associated with a state of relaxation and basically represent the brain shifting into an idling gear, relaxed and a bit disengaged, waiting to respond when needed. If we merely close our eyes and begin picturing something peaceful, in less than half a minute there begins to be an increase in alpha brainwaves. These brainwaves are especially large in the back third of the head.
Theta brainwaves (4-8 Hz) represent a day dreamy, spacey state of mind that is associated with mental inefficiency. At very slow levels, theta brainwave activity is a very relaxed state, representing the twilight zone between waking and sleep.
Delta brainwaves (0-3.5 Hz) are the slowest, highest amplitude brainwaves, and are what we experience when we are asleep. In general, different levels of awareness are associated with dominant brainwave states.
Each of us, however, always has some degree of each of these brainwave bands present in different parts of our brain. Delta brainwaves will also occur, for instance, when areas of the brain go "off line" to take up nourishment. If we are becoming drowsy, there are more delta and slow theta brainwaves creeping in, and if we are inattentive to external things and our mind is wandering, there is more theta present. If we are exceptionally anxious and tense, an excessively high frequency of beta brainwaves is often present. Persons with ADD, ADHD, learning disabilities, head injuries, stroke, Tourette’s syndrome, epilepsy, and often chronic fatigue syndrome and fibromyalgia tend to have excessive slow waves (usually theta and sometimes excess alpha) present. When an excessive amount of slow waves are present in the executive (frontal) parts of the brain, it becomes difficult to control attention, behavior, and/or emotions. Such persons generally have problems with concentration, memory, controlling their impulses and moods, or with hyperactivity. They can’t focus very well and exhibit diminished intellectual efficiency.
What is Neurofeedback Training?
Neurofeedback training is brainwave biofeedback. During typical training, a couple of electrodes are placed on the scalp and one or two are usually put on the ear lobe. Then, high-tech electronic equipment provides you with real-time, instantaneous audio and visual feedback about your brainwave activity. The electrodes measure the electrical patterns coming from the brain--much like a physician listens to your heart from the surface of your skin. No electrical current is put into your brain. Your brainwave patterns are relayed to the computer and recorded.
Ordinarily, we cannot influence our brainwave patterns because we lack awareness of them. However, when you can see your brainwaves on a computer screen a few thousandths of a second after they occur, it gives you the ability to influence and change them. The mechanism of action is operant conditioning. We are literally reconditioning and retraining the brain. At first, the changes are short-lived, but the changes gradually become more enduring.
With continuing feedback, coaching, and practice, we can usually retrain healthier brainwave patterns in most people. It is a little like exercising or doing physical therapy with the brain, enhancing cognitive flexibility and control. Thus, whether the problem stems from ADD/ADHD, a learning disability, a stroke, head injury, deficits following neurosurgery, uncontrolled epilepsy, cognitive dysfunction associated with aging, depression, anxiety, obsessive-compulsive disorder, or other brain-related conditions, Neurofeedback training offers additional opportunities for rehabilitation through directly retraining the brain. The exciting thing is that even when a problem is biological in nature, we now have another treatment alternative than just medication. Neurofeedback is also being used increasingly to facilitate peak performance in "normal" individuals and athletes.
Frank H. Duffy, M.D., a Professor and Pediatric Neurologist at Harvard Medical School, stated in an editorial in the January 2000 issue of the journal Clinical Electroencephalography that scholarly literature now suggests that Neurofeedback "should play a major therapeutic role in many difficult areas. In my opinion, if any medication had demonstrated such a wide spectrum of efficacy it would be universally accepted and widely used" (p. v).
"It is a field to be taken seriously by all" (p. vii).
Assessment Prior to Neurofeedback Training
Prior to doing Neurofeedback training, clinicians usually want to ask questions about the symptom history of the patient. In some cases they may do neuropsychological or psychological testing. Competent clinicians will also examine brainwave patterns. Some practitioners may do this by placing one or two electrodes on the scalp and measuring brainwave patterns in a few limited areas. Other clinicians perform more comprehensive testing called a quantitative electroencephalogram (QEEG) or brain map where 19 or more electrodes are placed on the scalp.
A QEEG is an assessment tool to objectively and scientifically evaluate a person’s brainwave function. The procedure may take about 1½ hours. It generally consists of placing a snug cap on the head which contains small electrodes to measure the electrical patterns coming from the brain. This is done while the patient is resting quietly with his or her eyes closed, and sometimes also with eyes open or during a task such as reading. Afterwards, we then go through a tedious and lengthy procedure to remove any artifacts that occurred when the eyes moved or blinked, when patients moved slightly in the chair, or tightened their jaw or forehead a little bit. The brainwave data we gathered is then compared to a sophisticated normative database of how the brain should be functioning at the same age. Over a thousand statistical analyses are then performed. This assessment procedure allows us to then determine in a highly scientific, objective manner whether and how a patient’s brainwave patterns are significantly different from normal.
Beginning during the 1970's and 1980's there began to be a great deal of experimentation with QEEG. The American Medical EEG Association Ad Hoc Committee on QEEG has stated that QEEG "is of clinical value now and developments suggest it will be of even greater use in the future." QEEG has scientifically documented ability to aid in the evaluation of conditions such as mild traumatic brain injury, ADD/ADHD, learning disabilities, depression, obsessive-compulsive disorder, anxiety and panic disorder, and a variety of other conditions (including autism, schizophrenia, stroke, epilepsy, and dementia). QEEG has even been able to predict outcomes from treating conditions such as ADD/ADHD, alcoholism, and drug abuse. The American Psychological Association has also endorsed QEEG as being within the scope of practice of psychologists who are appropriately trained, and ISNR has similarly endorsed its use by legitimate health care professionals who are appropriately trained.
The EEG and QEEG evaluations assist us in knowing if there are abnormalities in brain function that EEG Neurofeedback might be helpful in treating, and it allows us to know how we can individualize Neurofeedback to the unique problems of each patient. For example, scientific research has identified a minimum of three major subtypes of ADD/ADHD, none of which can be diagnosed from observing the person’s behavior, and each of which requires a different treatment protocol.
Once the assessment is complete and treatment goals have been established, we usually place two electrodes on the scalp and one or more on the earlobes during neurotherapy training sessions. The trainee then watches a display on the computer screen and listens to audio tones, sometimes while doing a task such as reading. These training sessions are designed to teach the person to slowly change and retrain their brainwave pattern. With continuing feedback, coaching, and practice, the healthier brainwave patterns are maintained. Some persons may need to learn to increase the speed or size of brainwaves in some parts of the brain. Other individuals need training to decrease the speed of brainwaves in certain areas of the brain. In a sense, it is like exercising or doing physical therapy with the brain, enhancing cognitive flexibility and control. Neurofeedback training usually requires at least 25, and most commonly 40-50 sessions of about 40 minutes in length.
ADD/ADHD & Learning Disabilities: Since the late 1970's, Neurofeedback has been researched, refined, and tested with ADD/ADHD and learning disabilities. Clinical work with Attention-Deficit/Hyperactivity Disorder and learning disorders by Dr. Lubar and his colleagues at the University of Tennessee and others has demonstrated that it is possible to retrain the brain. This Neurofeedback research is quite strong in demonstrating its effectiveness in treating ADD/ADHD. Whereas the average stimulation medication study follow-up is only three weeks long and the longest medication study is only 14 months long with ADD/ADHD, Dr. Lubar (1995) has published 10 year follow-ups on cases and found that in about 80% of patients Neurofeedback can substantially improve the symptoms of ADD and ADHD, and these changes are maintained. Rossiter and LaVaque (1995) found that 20 sessions of Neurofeedback produced comparable improvements in attention and concentration to taking Ritalin, and Fuchs et al. (2003) likewise demonstrated that Neurofeedback produced comparable improvements to ritalin. In a one year follow-up, control group study, Monastra et al. (2002) found that Neurofeedback produced superior improvements to ritalin, without needing to remain on drugs. Neurofeedback training for ADD/ADHD is commonly found to be associated with decreased impulsiveness/hyperactivity, increased mood stability, improved sleep patterns, increased attention span and concentration, improved academic performance, increased retention and memory, and increased IQ scores (often averaging 10 IQ points in published studies).
Epilepsy, Brain Injuries & Stroke. Uncontrolled epileptic seizures have also been effectively treated using Neurofeedback. Research in this area began in the early 1970's, and is very extensive and rigorous, including blinded, placebo-controlled, cross-over studies (reviewed in Sterman, 2000). Neurofeedback has been found to be helpful with all kinds of epilepsy, including grand mal, complex partial, and petit mal (absence) seizures. Although the larger proportion of seizure patients are adequately controlled by medication, most of the individuals who have been treated with Neurofeedback in research studies are among the most severe epilepsy patients, where anticonvulsant drug therapy was unable to control their seizures. However, even in this most severe group of patients, research found that Neurofeedback training on average produces a 70% reduction in seizures. In these severe cases of medically intractable epilepsy, Neurofeedback has been able to facilitate greater control of seizures in 82% of patients, often reducing the level of medication required, which can be very positive given the long-term negative effects of some medications. Many patients, however, will need to remain on some level of medication following Neurofeedback. Training often requires 50 sessions or more. Treatment outcome studies of closed and open head brain injuries are also now beginning to be seen, as well as with stroke, but better research still needs to be done in these latter areas.
Alcoholism & Drug Abuse. EEG investigations of alcoholics (and the children of alcoholics) have documented that even after prolonged periods of abstinence, they have lower levels of alpha and theta waves and an excess of fast beta brainwaves in their EEG's. This means that alcoholics and the children of alcoholics tend to be hard-wired differently from other people, and in a way that makes it difficult for them to relax. However, following the use of alcohol, the levels of alpha and theta brainwaves increase. Thus, individuals with a biological predisposition to develop alcoholism (and their children) are particularly vulnerable to the effects of alcohol. Without realizing it, alcoholics seem to be trying to self-medicate and treat their own brain pathology. The relaxing mental state that occurs following alcohol use is highly reinforcing to them because of the manner in which their brain is functioning. Several research studies now show that the best predictor of relapse is how excessive the beta brainwave activity is in alcoholics and cocaine addicts (Bauer, 1993, 2001; Prichep et al., 1996; Winterer, 1998).
Recently, EEG biofeedback training to teach alcoholics how to achieve stress reduction and profoundly relaxed states through increasing alpha and theta brainwaves and reducing fast beta brainwaves have demonstrated promising potential as an adjunct to alcoholism treatment. Peniston and Kulkosky (1989) used such training with chronic alcoholics compared to a nonalcoholic control group and a traditional alcoholism treatment control group. Alcoholics receiving 30 sessions of brainwave training demonstrated significant increases in percentages of their EEG record in alpha and theta rhythms, and increased alpha rhythm amplitudes. The brainwave treatment group also demonstrated sharp reductions in depression compared to controls. Alcoholics in standard (traditional) treatment showed a significant elevation in serum beta-endorphin levels (an index of stress and a stimulant of caloric [e.g., ethanol] intake), while those with brainwave training added to their treatment did not demonstrate an increase in beta-endorphin levels. On four-year follow-ups (Peniston & Kulkosky, 1990), only 20% of the traditionally treated group of alcoholics remained sober, compared with 80% of the experimental group who received Neurofeedback training. Furthermore, the experimental group showed improvement in psychological adjustment on 13 scales of the Millon Clinical Multiaxial Inventory compared to traditionally treated alcoholics who improved on only two scales and became worse on one scale. On 16-PF personality inventory, the Neurofeedback training group demonstrated improvement on 7 scales, compared to only one scale among the traditional treatment group. Thus, Neurofeedback training appears to hold encouraging promise as an adjunctive module in the treatment of alcoholism, and in remediating damage done through drug abuse.
Posttraumatic Stress Disorder. Peniston and Kulkosky (1991) added thirty 30-minute sessions of alpha/theta EEG biofeedback training to the traditional VA hospital treatment provided to a group of PTSD Vietnam combat veterans, and compared them at 30 month follow-up with a contrast group who only received traditional treatment. On follow-up, all 14 traditional treatment patients had relapsed and been rehospitalized, while only 3 of 15 Neurofeedback training patients had relapsed. While all 14 patients treated with Neurofeedback had decreased their medication requirements by follow-up, among traditionally treated patients, only one patient decreased medication needs, two reported no change, and 10 required more psychiatric medications. On the MMPI, Neurofeedback training patients improved significantly on all 10 clinical scales--dramatically on many of them--while there were no significant improvements on any scales in the traditional treatment group.
Other Clinical Applications of Neurofeedback Training. Neurofeedback has good research support for its effectiveness in treating anxiety (Moore, 2000). It is also being used to work with other clinical problems such as depression (Baehr, Rosenfeld & Baehr, 2001; Hammond, 2001), chronic fatigue syndrome (Hammond, 2001), fibromyalgia (Donaldson et al., 1998; Meuller et al., 2001), sleep disorders, Tourette’s, obsessive-compulsive disorder (Hammond, 2003), autism (Jarusiuwicz, 2002), Parkinson’s tremors (Thompson & Thompson, 2002), and essential tremor. Neurofeedback is being utilized in peak performance training, for instance in enhancing musical (Egner & Gruzelier, 2003), with athletes, business executives, for cognitive enhancement in normal college students (Rasey, Lubar, McIntyre, Zoffuto & Abbott, 1996), for memory enhancement in normal individuals (Vernon et al., 2003), and for "brain brightening" to counter effects of normal aging. However, these areas of application do not yet have strong research validation.
Although there are many health care practitioners who are convinced of the effectiveness and value of this cutting-edge technology (and an estimated 2,000 clinicians are using Neurofeedback, you should be aware that some insurance company personnel (whose job is to save their company money), and even some professionals (many of whom may not be aware of the latest published research), may regard all EEG Neurofeedback as experimental. Even for well validated biofeedback treatments, some insurance companies insist on defining all biofeedback as experimental and, thus, may not reimburse for these services.
Training Side Effects & Home Training
Only rarely have significant side effects from Neurofeedback training been noted. However, occasionally someone may feel tired, spacey, anxious, experience a headache, have difficulty falling asleep, or feel agitated or irritable. Many of these feelings pass within a short time after a training session. If you make your therapist aware of such feelings, they can alter training protocols and usually quickly eliminate such mild adverse effects. It has come to our attention, however, that some individuals are now renting and leasing home training equipment. It is our strong recommendation that training with equipment at home should only be done under the regular consultation and supervision of a legitimately trained and licensed professional, preferably following closely supervised training in the office for a period of time. Otherwise, more serious negative effects could possibly occur with unsupervised self-training. It is important to remember that the impressive success documented in research is based on work with qualified professionals, following careful assessment, and with training sessions that are supervised by the therapist rather than with unsupervised sessions taking place in an office or at home.

ABC Catalyst - reviews alternatives to medication in the treatment of ADHD MAY 2003
Many of the children currently taking drugs for ADHD may not need them, say Swinburne University researchers. The alternative, drug-free treatment known as neurotherapy may work for them. Neurotherapy is biofeedback for the brain and involves the children correcting their own faulty brainwave patterns by playing a computer game. Electrodes connect their brain to the computer, and by winning the game their brainwaves are gradually put right.
Sydney Morning Herald reports on Neurotherapy 4 March 2007
Support is growing for non-drug treatment of ADHD. A therapy that exercises the brain is producing the kind of results that only drugs were delivering for some people with attention deficit hyperactive disorder (ADHD). Electroencephalograph biofeedback (or neurotherapy) trains the brain to harness its inherent ability to learn about itself and change permanently. People with ADHD and learning disabilities often have sluggish brainwave activity and neurotherapy can increase a patient's ability to concentrate, learn and retain information.
