Brain Systems

It’s important to think of the brain as a series of systems, overlaid and inter-related.  The cerebellum plays an important role in motor memory. Eric Courschene is a well known researcher whose work in autism autopsy studies has shown that there is a reduction and disarray in the number of Purkinje neurons in the cerebellums of people with autism.  These are filtering neurons; they have much to do with the information that leaves the cerebellum to make its way to the frontal cortex. 

This deficit in the function of the cerebellum has a great effect on how the world may be perceived by a person with autism.  The world may look very chaotic and incoherent.  The cerebellum has a big job of coordinating the incoming visual, auditory and somatosensory information.  Depending on how the information is filtered on its outgoing trip to the higher parts of the brain, the ability to shift attention from one sensory issue to the next is in peril. 

The cerebellum is recently been implicated in how one functions socially.  It is an important area of the brain as the cerebellum is a star player in cognition.  The cerebellum is a major association center a major switchboard in regulating attentional states. 

The brain relies upon a sensitive system of feedback loops.  For instance, motor memory is achieved with a very sophisticated feedback system. In order for effective motor memories to operate the frontal cortex plans & organizes the events, while depending upon the basal ganglia & hippocampus to store memories in long-term storage banks.  The frontal lobe is termed the brain’s executive function. 

Auditory Integration Training Outcomes And Brain Neuroplasticity: Neuroplasticity & The Changing Landscape Of Attention In The Brain
Sensory input in itself it not responsible for brain change.  The most important factor is the attentional state.  Research by Michael Merzenich in 1993 indicates that passive stimulation doesn’t do the job of changing the brain circuits.  When monkeys listened to specific frequencies – auditory cortex landscape enlarged, but when the monkeys were distracted, they lost circuitry strength & landscape.  

For people with autism, information is unfiltered, poorly routed and they are unable to “pay attention”.  The sensory information speeds along too fast for them to catch and process.  Sensory integration must be intact in order for the perception of the world to make sense.  This is the ability of the brain to make new connections and assume new roles.  Plasticity follows an increase or decrease in sensory input. 

Neuroplasticity is concerned with taking over unused regions of the brain or remodeling the whole landscape.    The simple act of paying attention can make physical changes within the brain.  Attention is influenced by the limbic system & importantly the amygdala.  Experience molds the brain, but only a brain that pays attention.  Neuroplasticity or cortical reorganization is use induced.  Schwartz & Begley  Cells that fire together, wire together, strengthening the synaptic routings.  This means that the cells must “practice together” over and over again.  

Motivation And Emotion

Emotion is movement outward.  It conveys our important internal states and needs. The limbic system is an incredibly interconnect circuitry which is the launching point for emotions.  The upper cortex and the limbic system are in continuous feedback loop status. 

  • Motivation is a process the ties emotion & action. 
  • Motivation is the director of emotions. 
  • Motivation is the pressure to act. 

Auditory Integration Training Studies
There are some very important studies that show how Auditory Integration Training works. 

PET Scan Study

The first significant one is a PET scan study by High fill & Cimorelli, from North Carolina.  This is single-subject study using Positron Emissions Testing to show the changes in the brain pre-AIT & Post-AIT.  The PET scans show how much energy the brains use.  The PET graphs show more efficient use of energy in more areas of the brain.  This was an 8-year-old boy with mental retardation and autism.  The results showed a “normalization” of brain wave activity including a decrease in hypermetabolism of the frontal lobe and an increase in activity in the occipital lobe. 

Occupational Therapists’ Study

The second study mentioned in the slide is that of Sheila Frick and Nancy Lawton-Shirley, both occupational therapists, from Hudson, Wisconsin.  They felt that changes brought about by Auditory Integration Training facilitated improvement in movement perception with people who experienced gravitational insecurity prior to training.  They also noticed positive changes in overall arousal, organization and social-emotional responses.  They used a case-study approach with two sets of identical twins. 

New Zealand Study
The third study is also a case study conducted over a 6-month period of time in New Zealand.  This study involved 46 participants or varying diagnostic groupings.  It was conducted under the sponsorship of the Crippled Children Services in Tauranga.  The results of these case studies can be found on pages 95-111 of the Resources Guide 2005. 

There Are 28 Clinical Studies On Auditory Integration Training
The 28 studies posted on the Autism Research International website by Drs. Stephen Edelson and Bernard Rimland.  This analysis distinguishes the diagnostic groups, whether findings were in favor of Auditory Integration Training, or whether the study results were controversial and ambiguous and then whether the results were unclear and whether there were no effects.  None of the studies showed any effects.  Three studies indicated the studies had unclear results and two studies showed controversial/ambiguous or contradictory results.  Of the 28 studies, 23 showed positive results for Auditory Integration Training

  

Auditory Integration Training and the Counseling Center
What is Auditory Integration Training?
Auditory Integration Training or AIT was developed by Dr. Guy Berard, a practicing otolaryngologist (Ear, Nose and Throat or ENT physician) in Annecy, France. Dr. Berard originally invented AIT to rehabilitate disorders of the auditory system, such as hearing loss or hearing distortion (hyper-acute or asymmetrical hearing). After 30+ years of clinical practice and study, Dr. Berard has determined that distortions in hearing or auditory processing also often contribute to many behavioral or learning disorders. He has successfully used the AIT method to help individuals with attention deficit hyperactive disorder (ADHD), sensory issues, autism, dyslexia, hyperactivity, learning disabilities (LD), language impairments, pervasive developmental disorders (PDD), central auditory processing disorder (CAPD), attention deficit disorder (ADD), and depression. In the large majority of Dr. Berard's cases, AIT has significantly reduced some of the handicaps associated with the disorders listed above. The principles of AIT and a summary of various case histories, complete with copies of individual hearing tests before and after AIT, are presented in Dr. Berard's book, Hearing Equals Behavior which was published in French in 1982. A revised edition was published in English in 1993 by Keats Publishing, Inc. (ISBN: 0-87983-600-8)

Why is auditory integration training sometimes appropriate treatment for individuals diagnosed with autism, pervasive developmental disorders (PDD), central auditory processing disorder (CAPD), attention deficit hyperactive disorder (ADHD), attention deficit disorder (ADD), dyslexia, hyperactivity, language impairments, and learning disabilities (LD), etc.?

AIT was designed to normalize hearing. Distortions in hearing can sometimes be a significant contributing factor in the conditions listed above. Individuals with the abovementioned disorders can often have hearing that is disorganized, asymmetrical, hypersensitive or otherwise abnormal.

One possibility is that some of these individuals are hypersensitive to certain frequencies of sound. For example, one individual might be hypersensitive to the frequencies of 1,000 and 8,000 Hertz while her perception of all other frequencies falls within the normal range. In this case, the individual might become overstimulated, disoriented or agitated in the presence of sounds at 1,000 and 8,000 Hertz.

Another consideration is that an individual's hearing might be asymmetrical (signifiantly different between the two ears). When the right and left ears perceive sounds in an extremely different way, problems with sound discrimination can occur.

PLEASE NOTE:Some people might think only about the workings of the inner ears when they consider "poor", "normal" or "good" hearing. For this reason, it's worth emphasizing that the brain is a crucial part of the auditory system. AIT was designed to normalize the entire auditory system, so it is also aimed at changing how the brain processes and organizes the input received from the ears.

What does Auditory Integration Training involve?
An assessment of the prospective trainee's auditory system is conducted. If at all possible, this assessment includes an audiogram. The assessment will indicate whether the individual is an appropriate candidate for AIT. If training is undertaken, the information in the audiogram can be used to determine the proper settings for the electronic filtering device used in AIT.

During Auditory Integration Training, music from a stereo system (i.e., CD or cassette player) is sent through a specialized electronic device. The electronic device randomizes and filters the frequencies from the music source and sends these modified sounds into the trainee's ears through a set of headphones. The randomized frequencies mobilize and exercise the inner ear and brain. For example, the sound waves vibrate and exercise the muscles that control the three ossicles (the small bones in the middle ear). It is important to note that if the trainee's audiogram has indicated a hypersensitivity to certain frequencies, the electronic device will modulate and control the volume of those particularly sensitive frequencies.

The training is structured as follows:

  • Auditory Integration Training requires twenty sessions. Each session involves thirty minutes of listening time. Ideally, the trainee does two thirty-minute sessions daily for a period of ten consecutive days. Other options are possible spanning from eight to fourteen consecutive days.
  • A mid-point assessment is done after ten sessions to reassess the trainee's hearing and note any changes. Any necessary changes to the settings on the electronic device are made at this time.
  • A third assessment is given after the completion of the twenty sessions. After twenty sessions, the trainee's hearing should show significant improvement with all or most frequencies being perceived at or near an equal level. Please note that it can take up to one year for all behavioral changes and benefits to become evident.

What improvements have been reported by teachers, parents and trainees after completion of Auditory Integration Training?

  • Reduction of hyper-acute and/or painful hearing
    • Less complaints of sounds causing pain or discomfort
    • Reduction in noise or tinnitus in the ear
    • Less startle responses to loud noises
  • More appropriate vocal intensity (volume)
  • More appropriate affect, expression and interaction
  • Easier, more frequent interaction with others, including increased eye contact
  • Improved language discrimination or comprehension
  • Greater interest in verbalization and communication
  • Exhibition of age appropriate behavior
  • Improved academic performance
  • Improvement in social skills
  • Increased comfort level
  • Less impulsivity and restlessness
  • Reduction in distractibility
  • Less lethary
  • Less irritability
  • Increased independence and self-esteem

Are there any risks associated with AIT?
There is no evidence to indicate that Auditory Integration Training is harmful in any way. No drugs and no surgery are involved with this method.

Is Auditory Integration Training available in many locations in the United States?
Our "In-Home" program makes A.I.T. available everywhere in the world. A.I.T. is available in the United States, but not in many locations. This method was invented in France and has only been promoted in the U.S. in recent years by such organizations as The Georgiana Organization and the Autism Research Institute.

AIT first received extensive national attention when excerpts from The Sound of a Miracle: A Child's Triumph Over Autism were published in Reader's Digest in December 1990.

References to scientific studies regarding Auditory Integration Therapy are available through our newer web site: auditoryintegration.net.

What Is Auditory Integration Training Or AIT?

Berard Auditory Integration Training or Berard AIT was developed by Dr. Guy Berard, an otolaryngologist (Ear, Nose and Throat or ENT physician) in Annecy, France. Dr. Guy Berard originally invented AIT to rehabilitate disorders of the auditory system, such as hearing loss or hearing distortion (hypersensitive, hyposensitive, or asymmetrical hearing).

After 35+ years of clinical practice and study, Dr. Berard determined that, in many cases, distortions in hearing or auditory processing contribute to behavioral or learning disorders. In the large majority of Dr. Berard's cases, AIT significantly reduced some or many of the handicaps associated with autism spectrum disorders, central auditory processing disorders (CAPD), speech and language disorders, sensory issues including auditory, tactile or other sensory sensitivities (hyper or hypo), dyslexia, pervasive developmental disorder (PDD), attention deficit disorder with or without hyperactivity, anxiety, and depression.

Berard Auditory Integration Training was designed to normalize hearing and the ways in which the brain processes auditory information. For example, an individual tests as hypersensitive to the frequencies of 1,000 and 8,000 Hertz while perception of all other frequencies falls within the normal range. The individual becomes overstimulated, disoriented or agitated in the presence of sounds at 1,000 and 8,000 Hertz. Therefore, Berard AIT works to normalize the hearing response across all frequencies within the normal hearing range.

In another example, an individual's hearing is asymmetrical (significantly different between the two ears). When the right and left ears perceive sounds in an extremely different way, problems with sound discrimination can occur. Again, Berard AIT works to normalize the hearing of both ears.

Frequently Asked Questions

Who is a good candidate?
Children (age 3 or older) and adults with learning difficulties, speech and language disorders, sensory issues including auditory, tactile or other sensory sensitivities (hyper or hypo), central auditory processing disorder (CAPD), dyslexia, pervasive developmental disorder (PDD), autism spectrum disorders, attention deficit disorder with or without hyperactivity, anxiety, depression, poor eye contact, distractibility, concentration problems and other areas. Specifics will be determined and discussed in the evaluation.

What is the minimum/maximum age that someone can complete AIT?
The youngest age recommended by Dr. Guy Berard is 3 years old. There is no maximum age. We have seen great results with all age ranges of people even into the elderly. Please contact us directly for more information regarding special situations.

Is this covered by my insurance?
Many insurance companies do cover a portion of the fees. When you schedule the evaluation, we will check insurance benefits for you and inform you of coverage at the time of the evaluation.

Is financial aid available?
Yes, based on financial need. Scholarship applications will be reviewed once the initial evaluation has been scheduled and will be discussed at the time of the evaluation.

Do you offer an "In-Home" program? What equipment do I need?
Yes. The only equipment you will need is a CD player that has a jack to plug headphones into. We supply everything else. Our provider makes herself available to help supervise and monitor by telephone as you proceed through the program.

Is there any research on AIT?
Yes, in general 75-80% of candidates get positive benefits. There have been no reports of any long-term negative effects. For summaries of research see at the SAIT?s website:
http://www.autismwebsite.com/saitwebsite/aitsummary.html  

How many sessions do we need? Is this something we do just once?
There are twenty sessions to the program. We also include four additional assessments during and after AIT. Some people find one set of AIT sessions to be sufficient. However in some situations we find continued improvements with repeat sessions. This will be determined in the follow-up assessments.

Which treatment should be done first?
AIT is an excellent precursor to other therapies and training programs as it helps normalize the brain and sensory systems, which then enable the person to use other therapies more effectively. More specific and detailed information or recommendations focused on your child will be provided in the evaluation.

Do you offer the Berard method of AIT? What is the difference between the Berard method and others such as Tomatis or Samonas?
Yes, we offer the traditional Berard Method using the original Berard equipment the Audiokinetron) and Berard recommended protocols. The Berard method is the only method that has formal research substantiation rather than purely anecdotal reports. In general, Berard method is known for help with audiologic and nuerologic related issues that can also positively impact social and emotional issues. Most of the other auditory programs are based on the Tomatis method that promotes the idea of improvements in social and emotional issues (Tomatis believed, like Bruno Bettlheim, that autism was caused by a mother/child bonding problem and so focused more on the emotional/psychological areas rather than the audiological and neurological which Berard focuses on). For detailed comparisons and information on the different auditory methods please see:
www.autismwebsite.com/ari/treatment/tomatis.htm

My child can be difficult to work with. How can I get him/her to wear the headphones?
Most children find AIT to be calming, soothing, and relaxing once they get used to wearing the headphones. Start practicing beforehand. We usually see quick cooperation to the surprise of many parents. We have many years of experience and techniques that will help. We have only had one child since 1994 who was not able to complete the program.

Do you have references?
Yes, we are happy to provide a network of parent and participant’s names and phone numbers upon request.

 

Autism Research Institute (ARI)
Auditory Integration Training

Auditory integration training (AIT) was developed by Guy Berard in Annecy, France to help people with auditory processing problems. According to Dr. Berard, processing problems may occur if one hears some sound frequencies much better than other frequencies. For example, a person may be hypersensitive to the frequencies 2,000 and 8,000 Hertz, but hear all the other frequencies in the spectrum at a normal level. The frequencies to which a person is hypersensitive are referred to as 'auditory peaks,' and these peaks take on the appearance of a mountain range in one's audiogram.

AIT is accomplished by a device which randomly selects high and low frequencies from a music source (a cassette or CD player), and then sends these sounds via headphones to the trainee. In addition, if the trainee has auditory peaks in his/her hearing (as evident from an audiogram), those frequencies are filtered out completely (blocked out) or partially (stressed at only a low level) from the music. The trainee receives AIT twice a day, each time for 1/2 hour, for ten days. During the first five hours of AIT, the sound level for both ears is equal. For those individuals who have speech and language impairments, the sound level is reduced in the left ear after five hours of training. Since the right ear is connected more directly to the left hemisphere than the right hemisphere, and since the left hemisphere is responsible for processing speech and language, Dr. Berard believes that a higher sound level in the right ear will stimulate the left hemisphere.

An audiotest is conducted prior to the first listening session to determine whether the person has auditory peaks; a second audiotest is given after five hours of listening to determine whether the auditory peaks are still present and whether new peaks have developed; and a third audiotest is given after the completion of the listening sessions. According to Dr. Berard, after completion of the program, all frequencies should be perceived equally well; and the person should no longer have peaks in his/her hearing.

One caution: As Dr. Berard informed us and as we have noted independently, some people exhibit unexpected behavioral problems during the 10-day AIT period, such as agitation, hyperactivity, and rapid mood swings. Similar problems are reported for more traditional forms of sensory integration therapy. We are unsure of the reasons for these behaviors. One explanation is that these behaviors are occurring as a direct result of receiving AIT. However, it is also possible that these problems may be a result of changes in the person's eating patterns and activity level during the 10-day period. We have noticed that parents often coax their son/daughter with candy and junk food so they will sit quietly during the listening sessions. To support this observation, we observed such problems in both those individuals who received AIT and those who received a placebo in our pilot study on AIT. At this point in time, we do not have enough data to determine which, if either, of these explanations is correct.

Based on our own experience, and our conversations with Dr. Cecile Wuarin, the psychologist who worked with Dr. Berard, we feel that parents/caretakers should receive pre- and after-care consultation so they will be made aware of and be able to deal constructively with possible changes they may see in their son/daughter. For example, one possible change is an increase in attention span. If a person has a short attention span, it may be easy to redirect him/her away from a toy or task. However, if the person's attention span increases, he/she may become more stubborn and more difficult to redirect because his/her attention span is much longer. Other behavioral changes may include an increase in emotional behavior (e.g., anger, crying, reacting to other people crying), independence (e.g., leaving an area without permission), and social growth (e.g., increased interaction). We agree with Dr. Wuarin when she states that if the trainee changes, the family must also change in how they perceive and interact with their son/daughter. This failure to change is evident when a parent reports that their son/daughter is "on their nerves" because they are not acting the way they used to act. One goal of AIT is to get them "to act" more adaptively and age-appropriately. Recognition of this is essential (e.g., an 18-year-old who wants to go to bed at 11 P.M. instead of her current bedtime of 8 P.M.). In general, we believe that since understanding and working effectively with autistic people is much different than understanding and working with people with other disorders (e.g., mental retardation), pre- and after-care consultation should be handled by professionals who have experience working with autistic individuals.

At the present time, we do not know exactly how AIT may affect a person's behavior. One possible explanation is that AIT is actually conditioning the person to shift his/her attention more easily. Dr. Eric Courchesne of Children's Hospital in San Diego has recently found that autistic individuals have much difficulty shifting his/her attention from one stimulus to another stimulus. Since high and low frequency sounds are sent randomly to the trainee, AIT may be teaching the person how to shift his/her attention more rapidly and effortlessly; as a result, they may be better able to attend and thus understand the contingencies related to sounds and movement (e.g., hand gestures). Another possible explanation relates to the fact that autistic people are often described as "tuning out" others in their environment. By sending high and low frequency sounds randomly, the person cannot anticipate the sounds; and thus, he/she cannot tune them out. As a result, they are, in effect, being trained to "tune in." If one or both of these explanations are correct, then it is possible that individuals who do not have auditory peaks may also benefit from AIT. Finally, it is possible that the person starts to perceive sounds, especially speech, more clearly; and as a result, he/she will be better able to learn relationships between a sound and a behavior, object, action, and event. Even though all three explanations listed above are hypothetical, they do suggest how a person may possibly benefit from receiving AIT.

 

Jeena - Hope For Kids

Auditory Integration Therapy

AIT generally consists of a prescribed amount of time spent each day listening to a recording that uses a particular combination of sound waves to retrain the ear. The assumption is that individuals sometimes have difficulty processing the things they hear due to inaccurate intake.
For most of us, sound is conducted through the whole body (skin, hair, ear) & this is processed by the brain. With our kids, they may have problems with the conduction or with the processing. AIT is supposed to help on these fronts. 

Even though the AIT is effective for many kids, there may/not be some aggressive behaviors (or other behaviors), which may last for a few weeks after the treatment.

Tomatis AIT

  • You listen to classical music, through a special headset. The music is modified by the "Electronic Ear" to re-educate the ear and awaken the person's listening skills. Also you listen to specially prepared tapes of chanting, words or sentences and repeat them into a microphone. This feedback passes through the "Electronic Ear", then back through the headset, enhancing clear and fluent speech.

Auditory Integration Training

Auditory integration training (AIT) is a program designed to treat auditory processing disorders (APD) (previously termed central auditory processing disorders or CAPD). AIT is an intervention that aims to help an individual make the most use of his or her residual hearing, and so improve the ability to understand speech and sounds in the environment (Davis 1999, 189). AIT typically involves 20 half-hour sessions of listening to specially modulated music over a 10- to 20-day period. The program was pioneered by Alfred A. Tomatis and Dr. Guy Berard. Conventional audiology and medical organisations consider it to be an experimental procedure.

Auditory integration training (AIT) aims to address the sensory problems such as hearing distortions, hyper-acute hearing, and sensory processing anomalies, which are said to cause discomfort and confusion in persons suffering from learning disabilities, including Autistic Spectrum Disorders. These hypersensitivities are believed to interfere with a child’s attention, comprehension, and ability to learn.

The training typically involves the child attending two 30 minute sessions per day for ten days. The child listens to a musical program through headphones. The program is modified for each child with certain frequencies of sound filtered using an electronic device called an Audio-Kinetron.
