Q: Why are patients so pleased with your approach?
A: Recent news releases about adverse effects of drugs used for many problems, including ADD/ADHD, have concerned patients.  While we can use drugs, we like to focus on QEEG-guided Neurotherapy, a drug-free alternative that remediates many different problems. To know that both children and adults can function normally without the use of drugs is an important discovery.


Q: What are the advantages of QEEG-guided Neurotherapy compared to drug therapy?
A:  Drugs often do not “cure” problems, and have harmful side effects such as decreased appetite, insomnia, lethargy, or depression.  QEEG-guided Neurotherapy is non-invasive, holistic, and there are no significant side effects. It resolves (remediates) problems instead of temporarily suppressing or “masking” them. The patient becomes able to perform well on his own, without having to depend on drugs.


Q: Are there side effects from the therapy?
A: Only rarely, perhaps a tension headache. No long-term ill effects have been reported from QEEG-guided Neurotherapy to normalize brain wave activity.


Q:  How does QEEG-guided Neurotherapy work?
A: QEEG-guided Neurotherapy is the process of teaching the brain to correct abnormal brain wave patterns and to produce normal patterns. It resolves neurological, psychological, and learning difficulties.  After a neurological evaluation, an EEG (electroencephalogram) is administered.   Then, a computerized analysis is made of that EEG.  That analysis is called a Quantitative EEG, QEEG, or a “brain map”.  It is a comparison of the patient’s brain wave activity to the brain wave activity of others of similar age who do not have any problems.  Dr. Walker analyzes the QEEG to determine where brain wave patterns deviate from the norm and to determine where re-training of the brain is necessary; thus, the name QEEG-guided Neurotherapy

During a QEEG-guided Neurotherapy training session, electrodes are placed on the patient’s scalp while an EEG records brain wave activity.  The patient then plays a game, similar to a video game, or watches a movie.  When the patient produces normal brain waves, a positive reinforcement (feedback/reward) is given.  For example, if the patient is playing a video game, such as the old “Pac Man” game, the Pac Man moves when the patient makes the desired brain wave activity; otherwise, Pac Man slows or stops.  If the patient watches a movie during the session, the movie is on loud and clear (reinforcement/feedback) when brainwave activity moves toward a “normal” direction; otherwise, the picture flickers, fades, and the sound goes off.  In other words, when the brain produces abnormal brain waves (i.e., those associated with ADHD, anxiety, dyslexia, reading problems, etc.) no reward (reinforcement/feedback) is given (Pac Man does not move/the movie does not play). Since the brain is a “learning machine,” it will figure out a way to make more of the normal brain wave activity and less of the abnormal activity.  The patient is not conscious of his brain’s efforts to gain the reward.

After several sessions, when the brain has learned to make normal brain wave activity, symptoms cease.  At that point, the feedback is no longer needed.

This retraining of the brain is accomplished in the same way as other types of learning, by providing positive feedback when desirable behavior occurs. This form of learning is called operant conditioning (like learning to ride a bicycle). The effect is usually permanent. The process is painless and non-invasive.

Most researchers believe that this training results in the establishment of new connections or the strengthening of existing connections in the relevant brain pathways.  Dr. Jonathan Walker is an authority in this field.  At Neurotherapy Center of Dallas we use a method Dr. Walker developed, the modular activation/coherence approach which achieves superior results.


Q: What is an EEG (electroencephalogram)?
A: EEG is the abbreviation for electroencephalogram.  It is obtained by placing electrodes on the scalp and recording the electrical activity of the brain at 19 different brain areas.  The test takes about one hour and is painless.  This test is analyzed by Jonathan Walker, M.D., a board certified neurologist, and board certified electroencephalographer.  Dr. Walker’s professionalism is important at this phase of the process.  He can identify or rule out possible epileptiform (seizure) abnormalities, or other related problems that might exist.


Q. What is a QEEG (Quantitative EEG?) 
A: QEEG (quantitative EEG) is the abbreviation for Quantitative Electroencephalogram. It is also known as a Brain Map. The QEEG is derived by digitally analyzing the EEG. The data obtained by the EEG is run through several databases that compare data from the patient with individuals in the same age range who do not have the same problems as the patient.  Dr. Walker personally reads each QEEG, and from the QEEG analysis he makes individualized recommendations to guide the training sessions.


Q: Why is the QEEG (Brain Map) so valuable? 
A: Often times one or more symptoms of a problem will be evident (such as ADD or ADHD); however, other problems may exist—such as auditory or visual processing problems, reading problems, anxiety, or depression.   The QEEG (Brain Map), is more objective than other tests, and unlike many other tests, can identify such problems.  The training can then address all of the problems during the course of the treatment.  It must be noted, that many times problems masquerade as something else (such as ADD), but other problems exist.   Those problems are also significant, and need to be addressed for the patient to obtain optimal brain function


Q: Why don’t all practitioners use QEEG-guided Neurotherapy?
A: The treatment is relatively new.  Most practitioners have not been trained in EEG, QEEG, and QEEG-guided Neurotherapy.  A significant amount of hands-on experience is necessary to learn how to do it.  It is technologically intensive, and the equipment is expensive.  Some practitioners use types of neurofeedback that are not QEEG-guided; however, the results usually are not as successful as those guided by the QEEG.


Q: How many QEEG-guided Neurotherapy sessions are required? 
A: Since everyone’s brain is different, required sessions depend on the number and severity of the abnormalities found on the QEEG. Training may be accomplished in as few as 10 sessions, but on average, 20-50 sessions are required.  More sessions may be required for severe problems.


Q: How frequently should EEG-guided Neurotherapy training sessions be done? 
A: EEG-guided Neurotherapy is a learning technique (operant conditioning).  If training is done less than two times per week, the patient forgets, requiring more sessions.  Most patients train two times per week. With more frequent training, results are seen more quickly, but are not necessarily better.


Q: How long is a session? 
A: A typical session lasts about 30 to 45 minutes; however, individual patients may require longer sessions.


Q: Is the training painful?
A: No.  Both the assessment and training are painless and non-invasive.


Q: Is training successful for both children and adults?
A: Yes.  Our patients are between ages three and ninety-three.


Q: How successful is QEEG-guided Neurotherapy training?
A: QEEG-guided Neurotherapy training is almost always successful if the patient is cooperative.  The training may not go well if the patient is stressed, sleep deprived, uncooperative, or ill.


Q: Will I continue to take my medications during the therapy?
A: Dr. Walker monitors all medications. Usually medications can be decreased or eliminated with successful therapy.  The medication usually does not interfere with the therapy and may be continued until it is no longer needed.


Q: How young can a child begin QEEG-guided Neurotherapy sessions?
A: Usually children can begin training at about three years of age.  We also treat older children and adults.


Q: Will insurance pay?
A: Most insurance companies will pay.  If not, cash prices are available for patients without insurance.


Q: Are Saturday training sessions available at the Neurotherapy Center of Dallas?
A: Yes.


Q: What is the usual procedure at Neurotherapy Center of Dallas?
A: Patients first schedule an intake evaluation with Dr. Walker, a board-certified neurologist.  He determines if additional tests will be useful in helping to further diagnose the patient’s problems.  Diagnostic tests, such as the QEEG, are usually ordered, which is the second step.  When the test results are complete, a follow-up session with Dr. Walker is scheduled to explain the results and the plan for training sessions. Next, training sessions begin. Often another QEEG is ordered during the course of the sessions, or at the conclusion of a series of sessions, to determine the effectiveness of the training.


Q: Why should I choose Neurotherapy Center of Dallas rather than another clinic that does Neurotherapy?
A. Neurotherapy Center of Dallas is a medical clinic.  Dr. Jonathan Walker is intensely involved with the discovery and use of ways to help patients heal, rather than just to have their symptoms suppressed.  Dr. Walker combines his traditional neurological medical practice with other successful non-drug treatments such as QEEG-guided Neurotherapy.  Patients receive a thorough neurological evaluation and treatment. Each patient receives individualized treatment protocols based on Dr. Walker’s experience and expertise.


Q: What are Dr. Jonathan Walker’s credentials?
A. Jonathan Walker, M.D. is a Board Certified Neurologist who is also Board Certified in Electroencephalography and in BCIA certified in EEG Neurofeedback.  He is a nationally recognized pioneer in the field of Neurotherapy and a researcher in areas of learning difficulties. Dr. Walker is the President of the American Board of QEEG Technology and is past President of the Neurofeedback section of the AAPB.  He is the founder of the Neurotherapy Center of Dallas.
