What is the role of the Microbiome in my health?

Your microbiome plays a crucial role in nearly every aspect of your health. It's made up of trillions of microorganisms, primarily in your gut, that help with digestion, nutrient absorption, and maintaining a healthy immune system. A balanced microbiome supports proper digestion, helps fight off harmful bacteria, and even influences your mood and brain function through the gut-brain connection. When your microbiome is in balance, your body is better equipped to manage inflammation, regulate hormones, and maintain overall wellness. At Brain Health D.C., we recognize how important this balance is and work to support your microbiome through tailored nutrition and lifestyle approaches, helping you feel your best from the inside out.

What is dysbiosis?

Dysbiosis refers to an imbalance in the gut microbiome, which is the community of bacteria and microorganisms living in your digestive system. A healthy gut has a balance of beneficial bacteria that support digestion, immune function, and overall well-being. However, when this balance is disrupted—whether by poor diet, stress, medications, or environmental factors—it can lead to dysbiosis. This imbalance may cause symptoms like bloating, gas, digestive discomfort, and even impact your immune system and mood. Restoring gut balance is essential for promoting optimal health, and that’s something we focus on here through personalized nutrition and lifestyle strategies.

Is NeurOptimal a form of neurofeedback, and how is it different from traditional neurofeedback?

Yes, NeurOptimal is a form of neurofeedback, but it differs significantly from traditional neurofeedback approaches. Traditional neurofeedback is typically condition-specific and requires a trained practitioner to analyze brainwave data, set protocols, and adjust training to target specific brainwave frequencies associated with particular conditions (e.g., anxiety or ADHD).

NeurOptimal, on the other hand, is a dynamic, non-linear system that doesn’t require the practitioner to set specific goals or target certain frequencies. It offers feedback directly to the brain in real-time, allowing the brain to adjust its activity on its own. This “brain training” is designed to improve overall flexibility and efficiency, without focusing on specific diagnoses or problems. Essentially, NeurOptimal allows the brain to correct itself organically, based on its inherent capacity for self-regulation.

Functional Nutrition empowers you to use food as medicine, helping you heal from within.

What conditions can be treated using Functional Neurology?

Functional Neurology can be applied to a wide range of neurological and neurobehavioral conditions. Some of the common conditions treated include:

  • Concussion and post-concussion syndrome: Functional Neurology is often used to help individuals recover from the lingering effects of a concussion.
  • Chronic migraines and headaches: By addressing neurological imbalances, Functional Neurology can reduce the frequency and severity of migraines.
  • Dizziness and vertigo: Functional Neurology helps patients with vestibular disorders that affect balance and coordination.
  • Movement disorders: Conditions like Parkinson's disease, tremors, and dystonia can benefit from functional neurological approaches to improve motor function.
  • Developmental disorders in children: Autism, ADHD, and other developmental delays are often addressed through neuroplasticity-enhancing therapies.
  • Chronic pain and neuropathies: By rebalancing the nervous system, Functional Neurology can alleviate chronic pain syndromes.
  • Traumatic brain injuries (TBI): Therapies aim to restore cognitive and physical function after brain injury.
  • Learning disabilities: Functional Neurology can help with conditions like dyslexia and processing disorders by improving brain function. This approach is also used for balance issues, anxiety, depression, and cognitive decline, including early stages of dementia.

Are Functional Neurology treatments non-invasive, and do they involve medications?

Functional Neurology treatments are typically non-invasive and focus on stimulating the brain and nervous system through natural means, without relying on medications or surgery. Therapies include sensory stimulation, physical exercises, eye movement training, and cognitive drills, all of which are aimed at improving neurological function through natural processes.

While Functional Neurologists may work alongside other healthcare providers who prescribe medications, their treatments do not typically involve pharmaceuticals. Instead, they focus on using the body’s own ability to heal and adapt, making it an appealing option for patients looking to avoid invasive treatments or medications with side effects.

What is Functional Neurology, and how does it differ from traditional neurology?

Functional Neurology is a specialized approach to treating neurological disorders by focusing on how the brain, spinal cord, and nervous system function as a whole. Unlike traditional neurology, which often focuses on diagnosing and managing neurological diseases with medications or surgery, Functional Neurology emphasizes the dynamic functioning of the nervous system. It aims to improve or restore function through non-invasive therapies that leverage the brain's plasticity, or ability to adapt and reorganize.

In traditional neurology, the primary focus is on structural abnormalities, such as tumors, strokes, or nerve damage, and the goal is to manage symptoms, often with pharmaceuticals or surgery. Functional Neurology, on the other hand, looks at how various systems of the body are working together and addresses imbalances that may not be evident on MRI or CT scans but still contribute to dysfunction. The emphasis is on restoring optimal neurological function through individualized, often non-invasive, therapeutic techniques.

What is NeurOptimal, and how does it work?

NeurOptimal is a type of advanced neurofeedback system designed to optimize brain function by using real-time data on brain activity. It works by monitoring your brain’s electrical activity through sensors placed on your scalp. When the system detects any patterns of instability or turbulence in your brain’s electrical signals, it provides feedback in the form of auditory cues, typically through music or sound. These interruptions gently signal the brain to self-correct, leading to a more balanced and regulated state.

Unlike many treatments that target specific symptoms or conditions, NeurOptimal focuses on training the brain to be more flexible and resilient, which can enhance overall well-being. By doing this, the brain can better manage stress, improve cognitive function, and address emotional imbalances, essentially allowing it to reorganize itself and function more efficiently.

What is a “neurosensory integration (NSI) therapy”?

Neurosensory integration (NSI) therapy utilizes a touchscreen, fully customizable program that integrates the three primary senses of tactile information, vestibular (inner ear) function, and proprioception (muscle and joint information). Through a combination of eye movements, balance, and sensory input this program corrects and improves sensory processing disorders from a wide variety of conditions. The patient may complete these therapies standing, seated, or standing on a foam pad. 

What is “neurological rehabilitation”?

Neurological rehabilitation is a therapeutic approach focused on helping the brain and nervous system recover from injury or dysfunction. It is rooted in the science of neuroplasticity, which is the brain's ability to reorganize and form new neural connections throughout life. When the brain is damaged by conditions like stroke, traumatic brain injury, or neurological disorders, neuroplasticity allows it to adapt and compensate for lost functions. Neurological rehabilitation leverages this capacity by using targeted exercises and therapies that retrain the brain to regain movement, coordination, cognitive function, and sensory processing. Through personalized treatment plans, patients can improve their quality of life and restore neurological function over time.

What is “RPSS”?

RPSS or repetitive peripheral sensory stimulation is an electrical therapy used to activate the lower brain stem, the part of your brain responsible for control of your automatic functions like breathing and digestion. This part of your brain is also responsible for the calming responses in your body. RPSS is typically applied to the tongue to activate cranial nerves IX and X (hypoglossal and vagal) and also to the branches of the trigeminal nerve (cranial nerve V) that sends sensory information to the entirety of your brain stem. You will feel light pulsations on your tongue and face that feel a little bit like a tickle, or applied to skeletal muscle it will feel similar to a TENS unit. This therapy applies sensory information to the brain stem to better regulate the motor output of the higher function region of the brain, the cortex. 

What is “neurofeedback”?

Neurofeedback a.k.a. neurobiofeedback uses small electrical conductors applied to the ears and scalp to collect and reorganize real-time brain activity (called electroencephalography) when combined with specific sounds played through headphones to improve self-regulation of brain pulsations. Higher frequency brain pulsations (i.e. brain waves) are reduced to lower frequency brain waves through a computerized program to aid in sleep, deep meditation, and calming responses in the body. You do not feel anything while the electrodes are attached. The session is typically run for 30 minutes and involves reclining in a cool, dark room for that length of time. Bonus: if you feel drowsy and want to take a nap, go for it! The system does not require consciousness to be effective.

What is an “ionic foot detox”?

An ionic foot cleanse is a non-invasive, medical-grade technology used to remove toxins from your body. Toxins are endocrine and vascular disruptors that can affect the function of your organs and hormones. The feet are submerged in warm water and ions are pulsed through the water. The uses for this therapy are threefold: 1) to cause a relaxation response in the body from the outflow of ions; 2) the separated OH- and H+ ions act similarly to magnets in the water and attract the heavy metals and toxins in your bloodstream, removing them through the soles of your feet; 3) salt and other particle detoxification. Do not be alarmed if the water changes color during your session – the color change is due to the salts added to the water before usage and the corrosion of the metals as they are removed from your body. 

Why was “BTracks Balance Testing” recommended for me?

BTracks Balance Testing provides objective, measurable assessments and retraining of the sensory and voluntary motor control of balance. With visual biofeedback on either a stable or unstable support surface, it is used to assess patient’s performing tasks ranging from essential daily living activities to high-level athletic skills. This balance test assesses the three major systems that feed into the motor cortex of the brain to maintain an upright posture: your visual system, your vestibular system (inner ear), and the information from your muscles and joints that feed into the coordination center of your brain, the cerebellum. Scores are compared to other applicants in the same age, sex, and activity level groups – so a 10-year-old boy is not compared to a 35-year-old male athlete. 

Why was “RightEye Testing” recommended for me?

RightEye testing tells our practitioners about the functionality of different part of the brain through motor system of eye movements. To be clear, this test does not assess ocular function (i.e. the function of the optic nerve or the occipital/visual lobe) but rather the control of eye movements governed by different regions of the brain. The test takes just a few minutes to perform, but offers vital information on brain function that will be used to tailor therapies specifically to your individual case.

What is an “adjustment”?

An adjustment is a technique where a chiropractor or doctor of osteopathy applies a quick, corrective thrust to a joint that is out of its proper position. When a joint is misaligned, this interrupts blood, lymphatic, and neurological flow within the body. Adjustments are not specific for just the spine; they can be applied to the joints in your extremities (hands, feet, shoulders, etc.) and to the joints in your skull called sutures. The goal of an adjustment is to improve motion and physical function as well as reducing any pain around the joint. If you’ve ever turned your head or rolled your shoulders and heard a “pop”, that was an adjustment! However, please keep in mind that as one joint becomes misaligned the neighboring joint can become hypermobile – or move too much to compensate for the lack of movement in the other joint. When you self-adjust and hear the “pop”, you are likely moving the hypermobile joint and not the joint that is actually out of place. The adjustment (sometimes referred to as a manipulation) specifically corrects the misaligned joint. Additionally, do not be alarmed by the popping noise that sometimes occurs when a joint is repositioned. Sometimes the pop will happen, and sometimes it won’t. If the noise does not occur, that does not mean the joint wasn’t repositioned. The sound is caused by nitrogen being released from the joint – nothing more. The popping sound is called a “cavitation” and its presence or absence is dependent on the level of nitrogen in your system at the time of the adjustment and is not an indicator of whether or not the joint moved. 

What is “cranial adjusting”?

The junctions of the skull (called sutures) are made of dense fibrous tissue that when the joint spaces are improperly aligned can lead to headaches, migraines, and sinus congestion. Adjusting these sutures – either by the hands of a chiropractor or using a chiropractic adjusting instrument called an activator – will re-align the bones in the skull and relieve these symptoms. Cranial adjusting is also effective in ensuring that molding (appropriate skull development after birth) occurs for proper brain growth. The posterior fontanelle (or “soft spot”) closes around 2 months and the anterior fontanelle closes around 18 months. While these “soft spots” are necessary to ensure the baby’s head can fit through the birth canal, it is equally important to make sure they form properly with their developmental milestones. 

What is “dry cupping”?

Dry cupping is a therapy that dates back to Ancient China and Egypt. A glass, silicone, or earthenware dome is attached to the skin via suction to lift the skin away from soft tissue. This helps with pain reduction, blood and lymphatic flow, and inflammation reduction. Cupping can also be used as a form of deep tissue massage.
