Chronic Fatigue Caused by Vagus Nerve Infection?

 

Source: Dr. Jockers
If you have Chronic Fatigue Syndrome (CFS), you know its difficult to get a definitive diagnosis.  Confusingly, its symptoms resemble many other health conditions and there’s no single test for identifying it. You also know its symptoms seriously interfere with living your life as you’d like.
The principal characteristic of Chronic Fatigue Syndrome (CFS) is extreme fatigue. The fatigue may worsen with physical or mental activity but doesn’t lessen with rest. CFS is also sometimes referred to as myalgic encephalomyelitis (ME) or systemic exertion intolerance disease (SEID).
People with CFS – and other energy-sapping chronic conditions as well – often use Spoon Theory to describe their experience of being chronically exhausted and the limitations that imposes on their lives. Spoon Theory is a clever metaphor created by Christine Miserandino, a woman with both lupus and Chronic Fatigue Syndrome, to explain to friends and family what it’s like to have limited and unreliable energy.

AUTOIMMUNE CONDITIONS & DISEASES

Lupus, by the way, is a chronic autoimmune disease “in which the body’s immune system becomes hyperactive and attacks normal, healthy tissue. Symptoms include inflammation, swelling, and damage to the joints, skin, kidneys, blood, heart, and lungs.” (Brazier, 2018)
There’s still ongoing discussion about whether CFS is also an inflammatory, autoimmune condition. Considerable research indicates that chronic low level inflammation in the body leads to the constellation of symptoms described as Chronic Fatigue Syndrome. (Dellwo, 2018 A)

This is my shorthand description of how autoimmune conditions and diseases develop:
Chronic imbalance in the contents of the gut microbiome (gut dysbiosis) -–> leaky gut -–> chronic low level inflammation in the body, which eventually -–> one or more autoimmune diseases
Autoimmune diseases develop when the body’s immune system produces an inappropriate immune response against its own tissues. Because the vast majority of our immune system (70-80%) is located in the composition of our gut microbiome, this is where we need to focus to understand how we come to develop an autoimmune disease (probably more than one) and also how to reverse these types of diseases.
When the immune system stops recognizing as “self” something that’s a normal constituent of the body, it starts producing autoimmune antibodies that attack the body’s own cells, tissues and/or organs. This produces chronic inflammation that damages these body parts and leads to full blown autoimmune diseases.

A MORE THOROUGH EXPLANATION OF CHRONIC FATIGUE SYNDROME

Michael B. VanElzakker, PhD

Researcher Michael B. VanElzakker, now a neuroscientist affiliated with Massachusetts General Hospital, Harvard Medical School and Tufts University, has proposed a more specific explanation for how Chronic Fatigue Syndrome develops.
In a 2013 paper, Chronic fatigue syndrome from vagus nerve infection: a psychoneuroimmunological hypothesis, VanElzakker described his novel psychoneuroimmunological hypothesis as the VAGUS NERVE INFECTION HYPOTHESIS (VNIH).
In the 2013 paper he pointed out that Chronic Fatigue Syndrome researchers mostly agree that CFS symptoms seem to reflect an intense, ongoing immune response, possibly due to a viral infection. They therefore were focusing their research on trying to uncover the specific pathogenic agent in plasma and blood cells responsible for the syndrome – without success. (HHV-6 Foundation, 2018)
Instead, VanElzakker proposed that CFS develops from an infection of the vagus nerve.

“When immune cells of otherwise healthy individuals detect any peripheral infection, they release proinflammatory cytokines. Chemoreceptors of the sensory vagus nerve detect these localized proinflammatory cytokines, and send a signal to the brain to initiate sickness behavior. Sickness behavior is an involuntary response that includes fatigue, fever, myalgia, depression, and other symptoms that overlap with CFS.”
His Vagus Nerve Infection hypothesis of CFS contends that the syndrome’s cluster of symptoms are  “a pathologically exaggerated version of normal sickness behavior that can occur when sensory vagal ganglia or paraganglia are themselves infected with any virus or bacteria.
“Drawing upon relevant findings from the neuropathic pain literature, I explain how pathogen-activated glial cells can bombard the sensory vagus nerve with proinflammatory cytokines and other neuroexcitatory substances, initiating an exaggerated and intractable sickness behavior signal.”
Following this new hypothesis, it’s possible any pathogenic infection of the vagus nerve could cause CFS, resolving the ongoing controversy about identifying  a single pathogen.
VanElzakker’s hypothesis integrates two of the most important actors in CFS, the autonomic nervous system and the immune system, offering an explanation of what causes the brain to receive a non-stop stream of messages instructing it essentially to shut down the body by producing fatigue, pain and other disabling symptoms. It proposes that “nerve loving viruses trigger a difficult to detect  immune response which produces the fatigue and other symptoms present in chronic fatigue syndrome.” (Cohen, 2019)
The VNIH focuses on sensory nerves, “an increasingly hot topic in ME/CFS/FM” and coincides with an established model of fibromyalgia. If this hypothesis is correct, it will change how Chronic Fatigue Syndrome is viewed, researched and treated. (Johnson, 2013)
VanElzakker’s work on CFS has zeroed in on the human herpes viruses – with the human herpes virus 6 (HHV-6) at the top of his list of suspects. (HHV-6 Foundation, 2018)
See Human Herpesvirus 6 (HHV-6): Its Role in Disease – Links to Numerous Diseases for a list of diseases associated with HHV-6 types A and B.  (Dellwo, 2018 B)

The following two paragraphs from the HHV-6 Foundation’s article CFS: a herpesvirus infection of the vagus nerve? discuss, in fairly technical terms, VanElzakker’s theory  of how a human herpesvirus-6 infection of the sensory vagal ganglia or paraganglia could produce the intense symptoms found in people with Chronic Fatigue:
“During infection, the sensory vagus nerve sends a signal to the brain to initiate “sickness behavior,” an involuntary response characterized by fatigue, fever, myalgia, depression, and other symptoms that are often observed in patients with CFS. However, VanElzakker proposes that when sensory vagal ganglia or paraganglia are themselves infected with any virus or bacteria, these symptoms would be exaggerated. He notes that many of the symptoms of sickness behavior (such as fatigue, sleep changes, myalgia, cognitive impairment, depression and zinc depletion) are also mediated by proinflammatory cytokines and observed in CFS.
“Herpesviruses and certain intracellular bacteria establish latency in the vagus nerve and reactivate during periods of stress or illness, causing the release of proinflammatory cytokines. HHV-6 is a highly neurotropic virus and potent inducer of cytokines such as IL-6 and NFkB, which many groups have proposed as an etiological theory for the role of HHV-6 in neurological conditions such as seizures and epilepsy. If this low-level “chronic” infection is localized to the vagus nerve it would be undetectable in the plasma, but could be demonstrated through analyzing tissue biopsies of the vagus nerve, VanElzakker suggests. HHV-6 is well-known for invading the hippocampus and other parts of the limbic system, and also establishes residence in the human sensory ganglia along with other neurotropic herpesviruses including HSV-1 and VZV.” (HHV-6 Foundation, 2018)

 

THE VAGUS NERVE

The vagus nerve, historically called the pneumogastric nerve, is the 10th cranial nerve and interfaces with the parasympathetic control of the heart, lungs, and digestive tract. The vagus nerves are paired but are normally referred to in the singular. It’s the longest nerve of the autonomic nervous system in the human body. (Wikipedia, 2019)
As the two branches of the vagus nerve make their way between the brain and the gut, they connect to every organ they pass along the way.

THE VAGUS NERVE & THE GUT MICROBIOME CONNECTION

I’ve been intrigued by the vagus nerve since discovering it’s a key player in the Gut/Brain Axis – the constant, two-way communication taking place between our brains and our guts.
Source: First for Women
From my 2015 post How the Gut Microbiome Influences the Brain – and Vice Versa:
“Maybe you’re used to thinking of the brain in your head as your only brain – but your body actually has TWO BRAINS: In fact, the ‘brain’ in your gut does a lot more than digest your food. While this brain doesn’t produce thoughts, it contains its own independent nervous system along with more neurotransmitters and serotonin than the brain in your head.
“Sheaths of neurons are embedded in the walls of the entire alimentary canal. Technically known as the enteric nervous system, this gut brain measures about 9 meters (29.5 feet) from esophagus to anus and contains about 100 million neurons, more neurons than exist in either the spinal cord or the entire peripheral nervous system. Equipped with its own reflexes and senses, this second brain can control gut behavior independently of the brain. Here’s a single example to  give you an idea of the importance of the gut brain for the entire body:  About 90% of the fibers in the vagus nerve, the largest of the visceral nerves, carry information FROM the gut TO the brain – but not the other way around.” (Hardin 2015)
And how about this interesting information from  Our Second Brain – The Gut Mind:
“During vertebrate embryonic development a single clump of fetal tissue divides to grow into the gut and the brain. One section becomes the central nervous system (the brain and spinal nerves) while another migrates lower in the body to create the enteric nervous system embedded in the sheaths of tissue lining the espohagus, stomach, small intestine and colon.
“The two separate nervous systems connect via the vagus nerve running from the brain stem into the abdomen. This major trunk line is one of the longest nerves in the body. The gut and the brain are constantly signaling each other, back and forth, along the vagus nerve and also via chemicals released by the gut and transported to the brain. When one brain gets upset, the other becomes upset too. They work in conjunction with each other along the Gut-Brain Axis, each heavily influencing the other.” (Hardin, 2015)

HEALING VAGUS NERVE INFECTION WITH ESSENTIAL OILS

Source: esvitality.com
Jodi Sternoff Cohen is the founder of Vibrant Blue Oils, an author, speaker, nutritional therapist and a leading international authority on essential oils. These are her strategies for how to heal vagus nerve infections with essential oils:

Vagus nerve stimulation – Parasympathetic essential oil blend was designed to activate the vagus nerve to trigger the parasympathetic response.  Parasympathetic is formulated with the highly stimulatory clove oil and works much like more invasive techniques such as Transcutaneous Vagal Nerve Stimulation by stimulating the Vagus Nerve near the outer ear and allowing action potentials to be sent down the nerve to stimulate the normal anti-inflammatory reflex of the Vagus Nerve along with helping to regulate exaggerated signaling that contributes to sickness behavior and excessive fatigue and pain related symptoms…. To stimulate the vagus nerve, apply 1 drop of Parasympathetic™ to the vagal nerve (behind ear lobe, on mastoid bone on the neck).

Glial cell inhibitors can be used to calm the immune activation of glial cells in your brain.  Natural plants remedies, like essential oils, have been proven to suppress microglial activation and neuronal damage in research such as “Inhibitors of microglial neurotoxicity: focus on natural products” and “Development of a neuroprotective potential algorithm for medicinal plants”.

Essential oils are especially powerful as glial cell inhibitors as they unique     chemistry          (super small, fat soluble molecules), allows them to easily cross the blood brain barrier and suppress glial cell activation.  Research has found that Cinnamon Bark is highly effective at inhibiting microglial activation. According to the research, Cinnamon Bark “may recede neuroinflammation by suppressing microglial activation and play a key role in neuroprotection”.  Immune Support™ oil is high in levels of cinnamon and can be topically applied to the bottom of the feet or around the neck (dilute before applying to the neck) to help inhibit glial cells from over-activating the vagus nerve.  Anti Inflammatory™ also helps to turn off the inflammatory response in the brain and inhibit an over-active glial cell response.  To apply, place one drop one the base of the skull or place a drop of Anti Inflammatory™ oil on your fingertip, and rub fingers together to disperse oil. Take your fingers once over the entire scalp.

Antiviral treatments:  Essential oils are known for their anti-viral properties.

More specifically, research studies have found that essential oils ‘inactivate’ viruses in one of two ways: by inhibiting their ability to replicate and/or inhibiting viruses’ ability to fuse to cell walls and infect a host cell.

Essential oils have also been shown to positively support our own immune system, enhancing its ability to ward off pathogens and help modulate your immune system.

 Anti viral blends like Immune Support™ can be applied 2- 3 times daily on the throat (diluted) or the bottom of the feet, or Thymus™ can be used  stimulate immune function against infections, viruses and bacteria by apply 2-3 drops on the thymus (on breastbone at third rib) in a clockwise motion for 30 seconds and then stimulate the thymus by gently tapping.   Finally, supporting your lymphatic system with Lymph™ can help supports your immune response by both bringing nutrients to and helping to clear toxins and waste from every cell in the body.

My take away from all this:
Source: unknown
Since it’s known that  –
Chronic imbalance in the contents of the gut microbiome (gut dysbiosis) -–> leaky gut -–> chronic low level inflammation in the body, which eventually -–> one or more autoimmune diseases
– avoiding a vagal nerve infection and Chronic Fatigue Syndrome is yet another good reason to get and keep your gut microbiome in good balance.
