Francesca, a 17-year-old girl, struggled with a multitude of health issues that drastically impacted her quality of life. From difficulty sleeping and eating to chronic, painful constipation, , increased heart rate, and debilitating seizures, Francesca’s day-to-day existence was a constant battle. Her seizures, which began in 2011, persisted despite working with numerous neurologists and trying various medications over the span of a decade.
Francesca’s story is not unique; chronic health conditions affect a staggering number of children worldwide. According to the CDC, more than 40% of school-aged children in the United States have at least one chronic health condition, such as asthma, allergies, ADHD, or digestive issues, and many other estimates put the actual number well over 50% today.
At the heart of many of these chronic health challenges lies a critical yet often overlooked component of the nervous system: the vagus nerve. When there is vagus nerve damage or dysfunction, it can lead to a wide range of health problems that can significantly impact a child’s overall well-being.
In this article, we will delve into the fascinating world of the vagus nerve, exploring its anatomy, functions, and the critical role it plays in pediatric health. We will also discuss the connection between vagus nerve dysfunction and various chronic health conditions, as well as the potential of Neurologically-Focused Chiropractic Care in addressing these issues through vagus nerve stimulation (VNS).
What is the Vagus Nerve?
The vagus nerve, also known as the tenth cranial nerve or CN X, is the longest and most complex of the cranial nerves. This extensive nerve originates in the brainstem and extends down through the neck, chest, and abdomen, innervating various organs along its path. Its name, “vagus,” comes from the Latin word for “wandering,” aptly describing its wide-ranging course through the body.
The vagus nerve has a wide array of functions, which can be classified into sensory, motor, and autonomic categories:
- Sensory functions: The vagus nerve transmits sensory information from the throat, lungs, heart, and abdominal organs to the brain. This allows the brain to monitor the status of these organs and respond accordingly.
- Motor functions: The vagus nerve controls the muscles of the pharynx and larynx, enabling functions such as swallowing and speech.
- Autonomic functions: As part of the parasympathetic nervous system, the vagus nerve plays a crucial role in regulating involuntary processes, such as:
- Heart rate and blood pressure
- Breathing rate
- Digestive function and motility
- Inflammation and immune response
- Mood and emotional regulation
The vagus nerve’s role in the gut-brain axis is particularly noteworthy. By facilitating bidirectional communication between the gut and the brain, the vagus nerve helps modulate digestive processes, immune function, and even mood and behavior.
Additionally, those last two functions may come to surprise both parents and other providers when they come to know how essential vagal nerve tone and function is to regulating the immune response and inflammation, and to the regulation of mood, emotions, and behavior. Many families of children with Autism Spectrum Disorder especially have worked hard to combat neuroinflammation and emotional dysregulation through diet changes, detoxes, and so forth, and so often the key to results in those areas is actually vagus nerve stimulation.
Common Signs of Vagus Nerve Damage in Children
Children with vagus nerve dysfunction may experience various vagus nerve disorders, including:
- Digestive issues: Constipation, diarrhea, abdominal pain, and reflux
- Mood and emotional challenges: Anxiety, depression, and difficulty regulating emotions
- Sleep disturbances: Insomnia, sleep apnea, and restless sleep
- Immune system dysfunction: Frequent infections, allergies, and autoimmune disorders
- Sensory processing difficulties: Hypersensitivity or hyposensitivity to sensory stimuli
- Chronic pain: Headaches, migraines, and generalized pain
Depending on the extent and location of the vagus nerve dysfunction, these symptoms can occur in isolation or in combination.
Health Conditions Associated with Vagus Nerve Damage
Studies have linked vagus nerve dysfunction to various chronic health conditions in children, including:
- Chronic pain and inflammation: The vagus nerve plays a key role in regulating inflammation throughout the body. Dysfunction can lead to chronic pain syndromes and inflammatory conditions.
- Seizures and other neurological disorders: Vagus nerve abnormalities have been implicated in the development of seizures and other neurological conditions, such as epilepsy and migraine headaches.
- Autism spectrum disorder (ASD) and sensory processing issues: Research suggests that vagus nerve stimulation can help with autism and sensory processing difficulties, impacting social engagement, communication, and nervous system regulation.
- Gastrointestinal disorders: Given the vagus nerve’s critical role in regulating digestive function, dysfunction can lead to conditions such as irritable bowel syndrome (IBS), inflammatory bowel disease (IBD), and gastroesophageal reflux disease (GERD).
- Autonomic nervous system disorders: Vagus nerve dysfunction is a key component of autonomic nervous system disorders, such as postural orthostatic tachycardia syndrome (POTS) and vasovagal syncope.
Vagus Nerve Function and “The Perfect Storm” Concept
“The Perfect Storm” concept describes how a combination of factors can lead to vagus nerve dysfunction and the development of chronic health conditions in children. These factors include:
- Birth trauma: Complications during labor and delivery, such as prolonged labor, forceps or vacuum extraction, and cesarean section, can cause physical stress and injury to the delicate tissues of the vagus nerve.
- Early life stressors: Emotional stress, family discord, and adverse childhood experiences can impact the developing nervous system, leading to vagus nerve dysfunction.
- Environmental toxins: Exposure to environmental toxins, such as heavy metals, antibiotics, and pesticides, can disrupt the normal functioning of the vagus nerve and contribute to chronic health issues.
- Nutritional deficiencies: Inadequate nutrition, particularly during critical periods of development, can impact the health and function of the vagus nerve.
When these factors converge, they create a “Perfect Storm” that can overwhelm the developing nervous system and lead to vagus nerve dysfunction, setting the stage for chronic health conditions to emerge.
POTS and Vagus Nerve Dysfunction
Postural Orthostatic Tachycardia Syndrome (POTS) is a disorder of the autonomic nervous system that affects as many as 3 million Americans, primarily women. POTS is characterized by an abnormal increase in heart rate upon standing, along with symptoms such as dizziness, fatigue, brain fog, and digestive issues.
Research suggests that vagus nerve dysfunction plays a significant role in the development and progression of this condition. The vagus nerve is a key component of the parasympathetic nervous system, responsible for regulating heart rate, blood pressure, digestion, and immune function.
In individuals with POTS, the vagus nerve may be underactive or dysfunctional, contributing to an imbalance between the sympathetic and parasympathetic branches of the autonomic nervous system. This imbalance, known as dysautonomia, can lead to the hallmark symptoms of POTS, such as tachycardia, lightheadedness, and orthostatic intolerance.
Several factors can contribute to vagus nerve dysfunction in POTS, including:
- Physical trauma: Birth interventions, injuries, or surgeries that cause strain or damage to the neck and brainstem area can impair vagal tone and regulation.
- Viral infections: Conditions like mononucleosis, Lyme disease, and COVID-19 can directly inflame and damage the vagus nerve.
- Autoimmune disorders: Ehlers-Danlos syndrome (EDS), Mast Cell Activation Syndrome (MCAS), and other autoimmune conditions are associated with increased inflammation that can target the vagus nerve.
- Chronic stress: Prolonged mental and emotional stress can lead to a state of constant sympathetic “fight or flight” activation, which can “burn out” the vagus nerve over time.
When the vagus nerve is dysfunctional, it cannot effectively counterbalance the sympathetic nervous system, leading to a state of chronic autonomic imbalance. This can manifest as POTS symptoms and impact multiple body systems, including the cardiovascular, digestive, and immune systems.
Addressing vagus nerve dysfunction is a critical component of caring for POTS. By restoring proper function to the vagus nerve and promoting autonomic balance, individuals with POTS can experience significant improvements in their symptoms and quality of life.
PANS/PANDAS and the Vagus Nerve Connection
PANS (Pediatric Acute-onset Neuropsychiatric Syndrome) and PANDAS (Pediatric Autoimmune Neuropsychiatric Disorders Associated with Streptococcal Infections) are closely related conditions that cause a sudden onset of OCD-like behaviors, anxiety, tics, and other neuropsychiatric symptoms in children.
Growing evidence points to a connection between PANS/PANDAS and dysfunction of the vagus nerve.
The vagus nerve plays a crucial role in regulating the body’s immune and inflammatory responses. When functioning properly, it helps to keep inflammation in check and prevents the immune system from overreacting to triggers like infections. However, when the vagus nerve is not working optimally, as in the case of many children with PANS/PANDAS, it can contribute to a state of chronic inflammation and autoimmunity.
Children with PANS/PANDAS often have lower vagal tone, indicating reduced function of the vagus nerve and an imbalance in the autonomic nervous system. This can lead to a heightened stress response, increased inflammation, and a lowered threshold for immune activation—all factors that may contribute to the sudden onset of neuropsychiatric symptoms.
Several factors can contribute to vagus nerve dysfunction in children with PANS/PANDAS:
- Infections: Streptococcal infections, a known trigger for PANDAS, can cause direct damage to the vagus nerve through inflammatory processes. Other infections like Lyme disease, mycoplasma pneumoniae, and viral illnesses may also impact vagal function.
- Gut dysbiosis: Imbalances in the gut microbiome, often resulting from antibiotic overuse or poor diet, can disrupt the gut-brain axis and impair vagal signaling. The vagus nerve is a key component of this axis, facilitating communication between the digestive system and the brain.
- Birth trauma and subluxation: Physical strain during the birthing process, especially from interventions like C-sections or forceps deliveries, can cause misalignments and tension in the upper cervical region where the vagus nerve originates. These subluxations can interfere with proper vagal tone and regulation.
- Emotional stress and trauma: Chronic stress and adverse childhood experiences can lead to a state of autonomic imbalance, with an overactive sympathetic “fight or flight” response and an underactive parasympathetic “rest and digest” response mediated by the vagus nerve.
By understanding the vital role of the vagus nerve in regulating the immune system and influencing neuropsychiatric health, we can develop more targeted and effective approaches to help children with PANS/PANDAS reclaim their vitality and thrive.
Nervous System Dysregulation and the Vagus Nerve
Nervous system dysregulation, also known as autonomic dysfunction or dysautonomia, is a state of imbalance within the body’s central control network. This intricate system, which includes the brain, spinal cord, and a vast array of nerves, acts as the command center for all bodily functions. When the nervous system becomes dysregulated, it can lead to a wide range of physical, emotional, and cognitive symptoms that significantly impact a child’s quality of life.
At the heart of nervous system dysregulation lies the autonomic nervous system and its two main branches: the sympathetic nervous system (SNS) and the parasympathetic nervous system. The sympathetic branch, often referred to as the “fight or flight” response, activates during times of stress, while the parasympathetic branch, known as the “rest and digest” response, promotes relaxation and healing. In a healthy nervous system, these two branches work together seamlessly to maintain balance and homeostasis.
However, when a child experiences chronic stress or trauma, whether in utero, during birth, or in early childhood, their SNS can become overactive, leading to a state of constant hyperarousal. At the same time, their PNS, which is largely regulated by the vagus nerve, may become underactive, making it difficult for the body to relax, recover, and regulate itself.
The vagus nerve, the longest cranial nerve in the body, plays a crucial role in this process. It acts as the main component of the parasympathetic nervous system, connecting the brain to various organs and regulating key functions like heart rate, digestion, and immune response. When the vagus nerve is functioning optimally, it helps to counterbalance the effects of the sympathetic nervous system, promoting a state of calm and relaxation.
However, in children with nervous system dysregulation, the vagus nerve may be underactive or impaired, contributing to a wide range of symptoms such as:
- Digestive issues: Constipation, diarrhea, reflux, and abdominal pain
- Respiratory problems: Asthma, frequent infections, and difficulty breathing
- Cardiovascular symptoms: Rapid heart rate, palpitations, and dizziness
- Emotional challenges: Anxiety, depression, and mood swings
- Cognitive difficulties: Trouble focusing, memory issues, and learning challenges
- Behavioral signs: Hyperactivity, impulsivity, aggression, and social withdrawal
Several factors can contribute to vagus nerve dysfunction and nervous system dysregulation in children, including:
- Prenatal stress and maternal anxiety
- Birth trauma and interventions like C-sections or forceps deliveries
- Early life stressors and adverse childhood experiences
- Chronic infections and illnesses
- Environmental toxins and sensory overload
By understanding the crucial role of the vagus nerve in regulating the autonomic nervous system, we can develop targeted approaches to support children with nervous system dysregulation.
This is where the PX Docs’ Neurologically-Focused Chiropractic Care comes in and works to restore balance to the nervous system, enhance regulation and overall function, and vastly improve the healing capacity and quality of life for their patients, no matter their diagnosis or condition.
Vagus Nerve Stimulation for Improved Nervous System Health
Neurologically-Focused Chiropractic Care offers a unique and promising approach to addressing vagus nerve dysfunction and related health conditions in children.
Subluxations within the neurospinal system are best understood as patterns of neurological interference that trigger sympathetic dominance, dysregulation, and dysautonomia – fancy terms for when the body gets “stuck” in stress mode and can’t calm down or regulate properly. These stress patterns can interfere with the function of the vagus nerve, which plays a key role in rest, digestion, immune health, and emotional regulation.
Neurologically-focused chiropractors use advanced diagnostic tools like INSiGHT Scans to precisely locate where these stress patterns are showing up in a child’s nervous system. Then, with gentle and specific adjustments, we help restore balance, support vagus nerve function, and guide the nervous system back toward healing and regulation.
