Strokes, Inflammatory Concussions, and Vagus Nerve Stimulation

Strokes, Inflammatory Concussions, and Vagus Nerve Stimulation
May 4, 2019 Patrick Nemechek, D.O.

The sudden lack of blood flow to a region of the brain that results in damage to brain tissue is referred to as a stroke.  This concept is commonly understood by most patients and physicians.

But what is not widely known is that a stroke results in a wave of inflammatory stress throughout the brain that causes a secondary injury to brain tissue distant from the original stroke injury.

This is one source of brain injury that I often refer to as an inflammatory concussion.

The inflammatory stress throughout the brain is the result of a release of pro-inflammatory cytokines (chemicals released from white blood cells) and the abnormal activation of microglia (white blood cells in the brain) which culminates in the equivalent of a concussion.

Furthermore, many of the residual symptoms a person is left with after a stroke are from this inflammatory concussion and are now potentially reversible.

If someone experiences a stroke that affects their motor system such that they have weakness on one side of their body, they commonly experience chronic symptoms that originate in another area of the brain that was not directly damaged by the lack of blood but was injured by the inflammatory concussion.

For example, poor memory, fatigue, dizziness, poor balance, and constipation are common symptoms after damage to the autonomic nervous system from a physical concussion.  These same symptoms often occur after the inflammatory concussion effect of a stroke.

If the chronic weakness and immobility of an arm or a leg after a stroke are not bad enough, the addition of the autonomic dysfunction symptoms of poor balance, dizziness, and poor memory can substantially decrease the patient’s quality of life.

Fortunately, many of these secondary autonomic symptoms along with a portion of the residual weakness from the stroke itself are now potentially reversible with my patented science-based treatment program The Nemechek Protocol® for Autonomic Recovery.

The Nemechek Protocol® consists of methods, based on my medical consultative and treatment services, for preventing, reducing or reversing acute and/or chronic autonomic damage by the suppression of pro-inflammatory cytokines.   This encourages proper cell function, especially when combined with targeted Vagus nerve stimulation.

The Vagus nerve is the autonomic nervous system’s longest nerve and it carries most of the autonomic parasympathetic signals from the brain down to all the organs of the body.  The Vagus nerve also collects and transmits information that is gathered from throughout the body upward to the brain.

The body also primarily regulates inflammation though the signaling of the Vagus nerve.  It is the restoration of one’s proper inflammation control that becomes particularly important to healing when dealing with residual autonomic damage after a stroke.

Vagus nerve stimulation, abbreviated as “VNS”, with a surgically implanted device has been performed for almost twenty years in individuals with treatment-resistant epilepsy and depression.  It has proven remarkably safe and effective in the reduction of seizures and depression.

In the past few years the ability to perform VNS has expanded as the Vagus nerve can now be stimulated without the expense or risks of surgery. The Vagus nerve has a small nerve branch that lies just below the surface of the skin in certain areas of the ear.  This branch of the ear can be stimulated with an imperceptible electrical current and this is proving to have the same clinical benefits as the surgically implanted device.

I have developed the world’s only Vagus nerve stimulator that is controlled and powered by your cellphone.  When combined with The Nemechek Protocol® this simple and relatively inexpensive unit can result in significant recovery of prior stroke symptoms even years after the original event.

The Vagus nerve stimulator is typically worn two to four hours a day while the patient goes about their routine daily activities.  When combined with purposeful efforts and moving the limb affected by the stroke, the pathways involved with those efforts are preferentially restored and limb function may improve.

I have been using Vagus nerve stimulation for years both personally and in my medical practice and I understand how our bodies are capable of healing a number of inflammatory and other injuries even late into life when given the opportunity to do so.

I am an internal medicine physician and my private office is located in the greater Phoenix, Arizona area.

Hello Dr. My daughter is 13. Not autistic but developmental delays. We started inulin in Feb and gradually increased dosage until we got to 2tsp with no changes noticed. I have prescription for Rifaximin. Since it is a tablet, she won’t take it. Do you recommend to continue with inulin or start rifaximin? Is it ok to crush rifaximin and put it in a capsule?


I have just today learned that my family history of tia’s and strokes is an inherited gene mutation. Cadasil is the name and I guess its a mutation of the notch 3 gene. will the protocol help prevent a future tia/stroke for me? I’m in my late 40’s and very healthy.


Hi Dr,nemechek My son birthdate (05/01/2014), just completed 5 year this month. He has been into this protocol since Feb22,2019 (Just completed 2.5 months). I had taken an appointment from you ,which is scheduled at Feb-2020. Currently I am giving him 1/4th inulin, 1.5 ml ultimate omega Omega(2470 mg of EPA+DHA) and ½ tablespoon of Evoo cooc certified.Currently he has frequently pea accidents (after following protocol), lots of aggression and Hyper activity( before and after following protocol) , mad about water (i.e press water bottle, tea/coffee cup, open water tab, throw water from bucket or bottle, frequently putting his hand… Read more »

I normally share gains – and we’ve seen TONS – but I’m feeling frustrated today. Our (almost) 6 year old son has been on the protocol since this past July. We still don’t feel like we’ve gotten a handle on his constipation/withholding issues. When it’s bad, unless we use enemas, he will actively withhold bowel movements for two weeks. We’ve tried Calm Magnesium, prescribed senna, massage, acupuncture, Epsom salt baths, and probably more that I’ve forgotten to list. His gluten/dairy-free diet is generally healthy and full of fiber. He only drinks water and lots of it. We understand that constipation… Read more »


Hello Doctor, thank you for this amazing protocol! Can I give my almost 8 year old a round of rifaximin ( it’s easily available here) and then follow up with Inulin for maintenance? We have been on the protocol for 4 months and on double dose of oils. We see some slow improvement.he is on the spectrum ,has eses and absence seizures .we are due to see you later this year.
