Today you get another excerpt from Lyme Brain, which by the way is getting close to being released! Although these excerpts talk about Lyme Brain, the nutrient acetyl-L-carnitine can be helpful for many people, so if you don’t have Lyme disease, still have a read! It’s good for protecting the brain from aging and oxidative stress, and boosting the brain’s metabolism. The book Lyme Brain will be available through www.lymebrainbook.com for purchase in another week or two. Woohoo!!
In our ongoing series on brain health, particularly as it relates to Lyme Brain, I am posting today an excerpt from my upcoming book called Lyme Brain, on the link between glutathione and brain health.
I feel that olive leaf extract is often overlooked in Lyme treatment. Given it’s broad-spectrum antimicrobial properties and it’s ability to support the immune system, while also crossing the blood-brain barrier, I have seen olive leaf helps fight Lyme brain. In today’s excerpt from my upcoming book Lyme Brain, you’ll learn more about olive leaf extract and how valuable it can be – and not just for Lyme sufferers! It helps to protect the brain and help it to regenerate during times of illness or stress.
Lyme Brain. I’ve been giving you sneak peeks into my upcoming book, Lyme Brain. But this particular segment is not just related to Lyme disease – it’s good stuff for all of us, especially those with any health issues that impact their cognition and/or neurological function. Exercising the brain and keeping the brain active is important for keeping function as good as it can be!
As my upcoming book, Lyme Brain, gets closer to publication, I will continue to give you sneak peeks every Wednesday into some of its content. The book talks about a multitude of options for addressing Lyme Brain, including both pharmaceutical, nutraceutical and nutritional options. The nutritional/ supplemental form of lithium can help with Lyme Brain … here’s an excerpt about its use. Remember to go to www.lymebrainbook.com to sign up for early bird news about publication and to get the first copies off the press! [Read more…]
This is the million dollar question for those suffering from Lyme Brain: is damage temporary or permanent? The experience of having brain fog, memory loss, difficulty finding words and putting sentences together can be terrifying, frustrating and demoralizing all at once. In keeping with our series of excerpts from my upcoming book, Lyme Brain, I will post today on this exact topic. In fact, each Wednesday from now until the book is published in a couple of months, I’ll continue to share snippets with you! Don’t forget to sign up at www.lymebrainbook.com to be notified when the book is released.
Welcome to our series, What Causes Lyme Brain – Part 4. Today we are talking about neurotransmitter imbalance. This may be a cause or an effect of Lyme disease – imbalanced neurotransmitters such as GABA and serotonin can create anxiety and depression, and contribute to Lyme Brain, and can also be a secondary effect of chronic infection. Here is an excerpt from my upcoming book Lyme Brain:
Welcome to What Causes Lyme Brain (Part 3). In previous weeks we’ve discussed two of the underlying causes of Lyme Brain – the infections themselves; and the inflammatory response. Today we’ll talk about the third causes – neurotoxins. This is an excerpt taken from my upcoming book, Lyme Brain, which is due for release in the fall.
One of the ways that Borrelia burgdorferi may act to cause Lyme Brain is by releasing toxins in the brain and central nervous system. Neurotoxins are substances that enter nerve cells through the nerve endings, disrupting the function of the cell along the way. There are many sources of neurotoxins, both infectious and non-infectious in nature. Other examples are heavy metals, molds and Candida, as well as the chemicals that we are exposed to by the industrialized products and services we consume in modern society.
While the concept of a specific neurotoxin produced by Borrelia has been a controversial one, there is at least some research supporting it.
Researchers Cartwright, Martin and Donta presented an abstract at a conference in 1989, which identified DNA in the Borrelia bacterial genome that produces a neurotoxin. This was named BbTox1.[i]
This toxin is cited to be similar in structure to the botulinum toxin, belonging to a family of toxic proteins called zinc endoproteinases. Professors Bradford and Allen in their article in the Townsend Letter for Doctors and Patients (Feb/Mar 2006) claim that the Borrelia toxin works by disabling the neurotransmitter acetylcholine, which would then impact motor functions as well as psycho-emotional states.
In reality, there is fairly limited research in this area. A PubMed search of BbTox1 only revealed one match, a study from Poland citing the existence of BbTox1 but with no new information.[ii]
Another possible mechanism of neurotoxicity secondary to Lyme disease may be increased levels of ammonia. David Jernigan, DC, DNM, an integrative practitioner, founder of the Hansa Center for Optimal Health and developer of Jernigan Neutraceuticals, states that he discovered that the majority of Lyme patients have elevated levels of ammonia in their brain and potentially in other parts of their bodies, too, including the liver.
Here is an excerpt from Dr. Jernigan’s blog:
“It would seem that Bb releases ammonia, which is converted to glutamine by way of the glutamine synthetase pathways, leading to localized swelling of astrocytes (brain cells). This ammonia-induced glutamine accumulation may cause dysfunction of astrocytes, which leads to impairment of vascular reactivity (other than through a decrease in arginine availability for nitrous oxide) and increased production of nitric oxide…It has been reported that many neurological problems are caused by either congenital or acquired hyper-ammonemia.”[iii]
Dr. Dietrich Klinghardt, another well-known integrative doctor who works with many Lyme patients, also believes that ammonia in the brain may play a contributing role in Lyme Brain. He associates ammonia elevations with a condition called Kryptopyrroluria (KPU), aka Hemopyrrolactamuria (HPU). This is a metabolic disorder that impacts one’s ability to metabolize zinc, biotin, manganese, B6 and arachidonic acid.
Brain-related symptoms that may be associated with HPU include:
- Poor dream recall
- Perpetual disorganization
- Mood swings/emotional lability
- Stress intolerance
- Poor short-term memory
- Substance abuse
(List taken from reference below)
Dr. Klinghardt estimates the incidence of HPU in Lyme disease patients to be 80% or higher, in patients with heavy metal toxicity (lead, mercury, cadmium, and others) over 75%, and in children with autism over 80%.[iv]
He states that as HPU is treated, high levels of ammonia tend to normalize.
Clearly, biotoxins and neurotoxins seem compelling and may well be a significant and under-acknowledged cause of Lyme Brain. Much more research is needed in this area. In the later sections, which address the treatment of Lyme Brain, we’ll talk about the ways to minimize the effects of these neurotoxins.

Last week, I posted an excerpt from my upcoming book, Lyme Brain. We talked about the first cause of Lyme Brain, which is actual pathogens in the neurological system. Today you get the next installment What Causes Lyme Brain (Part 2) – the inflammatory response as a cause of Lyme Brain. Stay tuned next week for the third cause – neurotoxins.
The Inflammatory Response
As mentioned previously, direct impact of the pathogens on the nerve cells, which either causes demyelination or nerve cell death, is one way that Borrelia and its co-infections cause brain problems.
The second major mechanism is the inflammatory response. In fact, inflammation in the brain is perhaps the most significant cause of Lyme Brain.
Let’s review some basic physiology. Inflammation can occur for a number of reasons, but notably in response to a pathogen in the body that the immune system is trying to fight. Even though it can seem like a bad thing, it’s actually part of the body’s protective response. Inflammation can involve not only white blood cells, but also blood vessels in the area and cells in the damaged tissue, too. It is only a bad thing when the immune system becomes too active or the inflammatory response is prolonged.
When there is a pathogen such as Borrelia, the immune system activates to counter the threat and kill the pathogen. In doing so, the white blood cells of the immune system go to the affected area.
A whole cascade of events follows, the details of which are beyond the scope of this book. Suffice it to say that there are a few key features that are part of the inflammatory process.
One of these features is the production of cytokines. Cytokines are small proteins that are released by various cells of the immune system and function to facilitate communication and signaling between various cells. They orchestrate the trafficking of immune cells, direct them to the sites of injury and influence immune cell function. They are released by a range of immune cells including B cells, T cells, macrophages and mast cells. In very simple terms, they are messengers and facilitators. Types of cytokines include chemokines, interleukins, interferons, lymphokines and tumor necrosis factors. Cytokines can also influence Th-1 and Th-2 balance within the immune system, which is significant in chronic infections such as Lyme disease.
Chronic Lyme patients are found to have high levels of cytokines such as interferon-gamma, IL-10, TNF-alpha, interleukin-6, interleukin-1b, interleukin-8, interleukin-12 and C-reactive protein. Some cytokines are anti-inflammatory (IL-10 for example); however, the majority of cytokines found in Lyme patients are pro-inflammatory.[i],[ii],[iii]
Chemokines are chemicals that induce the movement of cells towards an area of damage or inflammation. Many chemokines have been found in Lyme patients: chemokine ligands CXCL12, CXCL13, CCL2, CCL3, CCL4 and CCL5.[iv],[v]
Nitric oxide (NO) is another inflammatory mediator. Nitric oxide is a reactive molecule that can cause oxidative stress and cell damage, giving rise to further inflammatory processes. Higher levels of nitric oxide have been found in Lyme patients as opposed to healthy subjects. Nitric oxide also controls blood vessel dilation and constriction, so nitric oxide levels may play a role in the blood flow and oxygenation of cerebral vascular tissue in Lyme patients.[vi],[vii]
In an article in the Townsend Letter (Feb/ Mar 2006)[x], Professor Robert W. Bradford and Henry W. Allen postulate that there might be a role for therapeutic agents that inhibit PDE-5, an enzyme that regulates c-GMP, which in turn influences nitric oxide. Medications that inhibit PDE-5 include sildenafil (Viagra), Cialis and Levitra. From a naturopathic standpoint, the amino acid arginine may have similar effects. Further research would be needed to determine whether this, indeed, is therapeutically significant and potentially beneficial for Lyme patients.
Another byproduct of immune activation is changes in the vascular system and blood clotting mechanisms. Inflammation creates increased dilation of the blood vessels and increased permeability in the vessel walls. This allows more fluid to move into the tissue space, giving rise to stasis of the blood cells in the vessels. This serves a worthwhile purpose: it allows white blood cells to move along the vessel walls to the site of injury (think of all the traffic on a freeway as it pulls over and stops on the side of the road to allow an ambulance through. If the traffic were flowing as it usually does, the ambulance would have a hard time making its way to the problem location). However, it can also lead to negative effects such as reduced oxygenation of the tissues.
So, we see that inflammation causes blood coagulation, but coagulation itself also has the capacity to regulate immune response, again, largely through the activation of various signaling molecules.[xi]
Coagulation is balanced by the fibrinolytic system, which acts as an anticoagulant, preventing ongoing blood clotting. Anticoagulants also function to reduce cytokine production and protect the endothelial cells from the damage caused by inflammation.[xii]
So you can see that while inflammation is a necessary part of immune response, it is not without its negative effects on the body.
Think of it like a military invasion. If an intruder comes on to home soil, the military (immune system) are going to counter that threat. They will first go to the location of the invasion, spreading out to the extent that the bad guys have spread out. They will come in with guns firing and missiles blazing. The goal is to kill as many of the baddies as possible with the least impact on the home turf. But, in the process of the invasion, some collateral damage may occur. Yes, the military might kill at least some (hopefully all) of the bad guys, but they may also take out a few local civilians, buildings might get blown up, and infrastructures may be destroyed. Some of this may be necessary to contain the original threat, but it’s certainly not the goal of the military’s defense strategy. Hopefully, once the invaders are neutralized, rebuilding of home base can occur to repair any collateral damage.
And so it is with inflammation in Lyme disease. When the immune system tries to protect the body from an invasion by pathogens, baddies will be eradicated, but inflammation will occur as a byproduct, which can damage tissues and create symptoms of its own. This is one of the necessary secondary effects but is also the mechanism for much of the collateral damage that we see.
In chronic Lyme disease, collateral damage is often more extensive, due to the fact that the battle is ongoing over months and years, compared with shorter battles that occur in acute infections.
