Treating Chronic Symptoms With

Biofeedback & Low-level Stimulation

TetraLexRN can have a positive impact on symptoms that emerged as a result of threatening or traumatic experiences at different stages of our lifespan and development. Our brain's primary function is to facilitate survival. Through low-level stimulation and biofeedback and neurofeedback, a sense of calm and ease will emerge that builds a base for better learning and movement forward into an embodied sense of one's life.


Often, for people with ADD/ADHD, they are at the whim of their senses as well as their emotions and thoughts. They behave as a rider without reigns. ADD/ADHD can be either inherited or acquired. It can lead to functional impairments and low self-esteem.

Biofeedback Treatments for ADD/ADHD

TetraLexRN allows the down-training of ADD/ADHD to depend on the context in which it occurs. Up-training focus can be done successfully with neurofeedback. Nutritional recommendations, exercise, supplements and sleep may optimize neurofeedback training. Sometimes it is recommended that these life-style changes be made first so that the efforts made with neurofeedback will have a greater chance of settling into a new pattern.

Outcomes of Treating ADD/ADHD with Biofeedback

After working with TetraLexRN’s training program, attention can be a gift that is bestowed with more generosity. Depending on the context, people report improved reading abilities and comprehension, problem-solving, creative thinking, math skills, ability to focus stronger and for longer, as well as being able to tap into their receptive and expressive language skills.

Anxiety Disorder

Being anxious can be exhausting or it can be exciting. Anxiety is often present as a messenger and if we listen, it can be informative of the next steps we need to take. If the anxiety is out of proportion to the problem, then biofeedback may help as a modulator. Biofeedback gives the individualized how to the suggestion relax. Also with assessment, it is possible to get a better picture of what EEG activity might be entangled with the anxiety.

Biofeedback Treatments for Anxiety Disorder

Often, having one’s anxiety disappear, will cause more anxiety. Therefore, decreasing the volume of the anxiety through down-training high-frequency activity can serve as a model to the brain of what it feels like to get quiet. Low-frequency low-level stimulation, as well as neurofeedback and heart rate variability, begin to take the sharp edge of anxiety down.

Outcomes of Treating Anxiety Disorder with Biofeedback

Once the EEG activity is untangled, triggers for anxiety are easier to identify and then reactivity can be more of a choice.

Autism Spectrum Disorders (ASD)

Autism spectrum disorders are important to identify and address. As a complex neuro-developmental and behavioral disorder, there are challenges with social interactions, language and sensory processing issues. Individualized assessments help clarify the brain activity that is driving the issues.

Biofeedback Treatments for Autism Spectrum Disorders (ASD)

Perspectives vary on how to train and do therapy with the symptoms of ASD. The values of the individual are prioritized and integrated into the plan for interventions. First, a low-level stimulation device may be used to help give the frequencies we will be asking the brain to create more of and the individual to uptrain. PEMF, pulsed electromagnetic field therapy can be used at different placements on the body and custom-tailored to the individual’s excesses and deficiencies at different frequencies. HEG biofeedback or Neurofeedback may be used to improve connectivity with the client getting to ?play? a movie with their brainwaves.

Outcomes of Treating Autism Spectrum Disorders (ASD) with Biofeedback

Symptom reduction through training and therapy can be maintained over time, and time it will take. Often there are layers of learning that can be accomplished and then a break is taken and we begin again once it is clear that integration of benefits has taken place. Big changes can occur in people with ASD’s access to their abilities and their integration into classrooms and other social situations.


Depression can stop life dead in its tracks if it is ignored over a long period of time. There are associated brainwave patterns with different types of depression. It is important to get an EEG recording with a depressed individual to gain the electrical signaling perspective of this disorder. It is well known that exercise can help with depression but too often people get stuck in the depression. This makes getting out to exercise is difficult to imagine.

Biofeedback Treatments for Depression

Biofeedback training attempts to allow movement on the cortical level so that then moving on the actual physical level is more effortless. If there is low metabolic activity in the EEG, one approach may be taken which would be different than if there is high-frequency high amplitude activity indicative. This would be indicative of an anxiety-driven depression and suggest a different approach.

Outcomes of Treating Depression with Biofeedback

Finding joy in life is possible and often reported after brain training. Feeling hopeful and ready to respond in an adaptive way will often emerge as one engages in both passive and active training of the neural regions associated with their depression.


It is important to learn whether a person has difficulty falling asleep (sleep onset latency) or difficulty staying asleep (middle of the night awakening) or both. If the causative factors can be determined; the best course for progressing can be determined.

Biofeedback Treatments for Insomnia

Intensives with low-level stimulation and neurofeedback can allow the brain to rehearse the settling down and going into restful ease that is needed to let go into sleep. Sleep is how we get from one day to the next. Certain sleep stages are when the cleaning of toxins is able to occur. This is one of the reasons why we sleep.

Outcomes of Treating Insomnia with Biofeedback

Falling asleep easier, sleeping for longer without awakening, and then feeling refreshed upon awakening are attainable goals and with focus on sleep is a priority, can be met. With better sleep comes better abilities. Improvement with concentration, memory, and learning are expected outcomes of improved sleep.

Traumatic Brain Injury (TBI)

After a brain injury, the EEG from the damaged area may show an abnormality in firing when a CT or MRI scan does not. EEGs show functional activity. During repair, inflammation may occur and EEG slowing may be noted as the brain attempts to heal itself. The undamaged areas are thought to compensate in order to keep the body moving and the brain thinking.

Biofeedback Treatments for Traumatic Brain Injury (TBI)

Neurofeedback, either passive or active, can be helpful in restoring levels of functioning Neurofeedback is indicated with mild to moderate TBI. A variety of the low-level stimulation devices are also indicated to bring resources to the brain as it works on the repairs and challenges it faces.

Outcomes of Treating Traumatic Brain Injury (TBI) with Biofeedback

It is possible for a person to move forward better than was expected post-TBI with the addition of low-level stimulation and neurofeedback to their treatment plan. It is not to be expected that they will go back to how they were prior to the injury. In some ways, they may. In some ways, they may perform better than before their injury. Some functions may not be recovered.

Post-Traumatic Stress Disorder (PTSD)

Trauma often includes an event with a sense of being unable to escape in a threatening circumstance. The meaning of the circumstance to the individual is important to understand. The context in which the trauma occurs and what follows is encoded. Troubling emotions may be present or they may be suppressed. Left untreated, sensory input that the individual may or may not be aware of can be triggering. Often a heightened degree of vigilance is present and visible in the signature of their EEG recordings.

Biofeedback Treatments for Post-Traumatic Stress Disorder (PTSD)

The training for PTSD includes meeting someone where they are and building a plan together. Establishing trust and managing expectations is important. Often, less is more at the beginning of this training relationship and the client and clinician are working together carefully to understand the needs and wisdom of the brain.

Outcomes of Treating Post-Traumatic Stress Disorder (PTSD) with Biofeedback

Staying emotionally connected and present without being flooded and having access to focus and energy without being on overdrive can be hoped for when the training is working. Nervous stomach, muscle tension, and other physical symptoms may ease.


A person may have either focal or generalized seizures. They may occur for a variety of reasons that manifest in abnormal electrical activity in the brain and subsequent changes in behavior, emotion or thinking.

Biofeedback Treatments for Seizures

Depending on what the assessments indicate, low-level stimulation and neurofeedback may be suggested to allow the return of flexibility to the brain. Through reward, the brain can learn to fire at a different frequency than what dominates during a seizure. The brain can also learn to inhibit the activity associated with the seizure in the affected area(s) of the brain.

Outcomes of Treating Seizures with Biofeedback

An expected outcome is that the intensity of the seizures will be less and the duration will be shorter. At first, what is most common is a long time without any seizures. Having a seizure-free EEG is possible although it sometimes takes more frequent training. The training can be done remotely, with clinical supervision, for access to more frequent training in the comfort of ones? own home.


Post-stroke symptoms can lead to impairments in functioning that can lead to temporary or lasting disability. Due to the interruption in blood flow, brain cells at the location of the stroke are affected.

Biofeedback Treatments for the Symptoms of a Stroke

Our treatments and training will adapt to your circumstances. Often a multi-factorial approach including low-level stimulation and heart rate variability biofeedback is where stroke recovery begins at TetraLexRN.

Outcomes of Treating the Symptoms of a Stroke with Biofeedback

The brain has a better chance of being able to heal itself with access to the proper resources that a regulated circulatory system can provide. When blood pressure & flow are optimized, the brain is able to get the proper resources it demands. Returned ease of movement and language are hoped-for outcomes.


Thinking and memory problems that can occur after chemotherapy in treating some cancers are referred to as chemo-fog or chemo-brain. Reports of increased confusion and disorganization can be debilitating. The side effects associated with the chemotherapy treatment negatively impact the survivor’s quality of life.

Biofeedback Treatments for the Symptoms of Chemotherapy

The lymphatics of the brain, referred to as the glymphatic system, takes care of waste removal from the central nervous system. Low-level stimulation and EEG biofeedback are used to decrease stress and encourage and increase the lymphatic system as it does its job. Other supports through diet, nutrition, and sleep are encouraged.

Outcomes of Treating the Symptoms of Chemotherapy with Biofeedback

Measurable and palpable improvements are experienced for those that suffer from chemo-fog. Less confusion, more ease of multi-tasking, and better memory are the positive outcomes.

Cognitive Impairment

Signs of mild cognitive impairment (MCI) include forgetting events and appointments, losing things often, and having trouble coming up with words more than others your age. MCI can be linked to genetic disorders. It can result in troubling emotional and social effects as well.

Biofeedback Treatments for Cognitive Impairment

Data-driven interventions along with clients’ values of what improvements will be most meaningful to them are woven into the interventions for MCI and often include LENS, HRV, and EEG biofeedback.

Outcomes of Treating Cognitive Impairment with Biofeedback

Improved performance on neurocognitive testing and an improvement in one?s IQ score is a consistent outcome with biofeedback and low-level stimulation with clients with mild cognitive impairment. Outcomes include improved memory, attention, and cognitive flexibility

Chronic Constipation

Chronic constipation is when a person has less than three bowel movements in a week. The discomfort can be debilitating. Chronic constipation can result in reduced quality of life, poor appetite and gastric reflux, lack of joy and anxiety.

Biofeedback Treatments for Chronic Constipation

The interventions for this disorder will include PEMF therapy delivered to the abdomen, HRV biofeedback and tACS (transcranial alternating current stimulation) to build coherence in the autonomic nervous system is also used. LENS and infra-red therapy may also be used. With chronic constipation, consultations in regards to supplements and nutrition are also available. A thorough review of medications and supplements that may be contributing to this disorder will be done.

Outcomes of Treating Chronic Constipation with Biofeedback

It is expected that a person will be able to have at least six bowel movements a week while they are continuing to get the PEMF therapy. It will depend on the person whether or not this will be needed as ongoing therapy.


Fibromyalgia is characterized by widespread musculoskeletal pain sensations that are thought to be a brain processing disorder. It is accompanied by fatigue and mood issues.

Biofeedback Treatments for Fibromyalgia

LENS (low energy neurofeedback system) has proven to be a successful therapy for the symptoms of fibromyalgia. The focus of therapy is to decrease reactivity and increase improvement in processing sensory input.

Outcomes of Treating Fibromyalgia with Biofeedback

Expected outcomes of neurofeedback in addressing the symptoms of fibromyalgia are a reduction of pain sensations, increased energy, and improvement in mood.

Headaches & Migraines

An appropriate assessment of the instigating variables that contribute to a headache or a migraine is very important. Structure and function both come into play with headaches and migraines. Where there is overactivity, whether it be in the nerves, blood vessels, tensing muscles, pressure systems or chemical cascades, often the result is a headache or a migraine.

Biofeedback Treatments for Headaches & Migraines

A good history is taken and an appropriate nursing diagnosis with an appropriate plan for intervention is the initial primary aim. Alleviation of the suffering that comes along with headaches & migraines comes second.

PEMF, LENS & HRV biofeedback known for their ability to increase circulation may be suggested.

tDCS, known for its ability to increase electrolytes, excitation, and metabolism in the treated area is often impactful and an option for home training.

Passive infra-red (PIR) HEG biofeedback has a long history of being a successful intervention with migraine headaches.

Outcomes of Treating Headaches & Migraines with Biofeedback

Vasodilation, reduced inflammation, and improved circulation often allow a surprising reduction in headache intensity and a shortened duration with migraines. Sometimes the training is described by clients as feeling like the opposite of a headache.
