Long COVID and the Brain

Most people who get COVID, especially if they are vaccinated, will recover without residual symptoms. But for some people, COVID infection can result in long-term health issues. So-called “long COVID” sufferers can experience many symptoms including crushing fatigue, dizziness upon standing up or standing too long, exercise intolerance, anxiety, headaches, heart palpitations, shortness of breath, brain fog, and more. Similar post-viral syndromes can result from other viruses too, and a very similar phenomenon can happen after concussions. The common thread is that when the brain suffers a blow, either literally or via the inflammation associated with a virus, the nervous system that runs almost every process in the body can be knocked off its axis. Across Canada, researchers and physicians are scrambling to try to understand how to help this new wave of people afflicted with a condition that is untestable and for which there are no simple drug solutions. Patients often feel frustrated and isolated. A greater understanding of what’s going on can help us target solutions for symptoms and speed the healing of the brain and nervous system. 

A patient I’ll call Emily had previously been in good health, so when she contracted COVID as an unvaccinated person ten months ago, she thought she would recover well. She did get over the acute symptoms of cough and congestion but was left with a mysterious assortment of symptoms that derailed her life. She has profound fatigue, dizziness when she stands up or stands for more than ten minutes in one place, and daily headaches; in addition, her mental processing and memory are impaired. When she tries to exercise, she crashes and is exhausted for two days. She has nausea and IBS. Her fingers go white when she gets cold, and her skin can be blotchy. Her periods are irregular for the first time. Anxiety seems to hit randomly, day or night, and depression is creeping in. 

Emily’s symptoms indicate that the nerves in her brain have been damaged. The brain governs the autonomic nervous system, which runs all the automatic processes in the body such as blood pressure, heart rate, circulation, balance, energy production, hormones, adrenalin release, sleep cycles, digestion, and more. When this critical system isn’t working right, we refer to this disorder as dysautonomia.  As a naturopathic physician, I treat people with complex, chronic conditions every day, so I have seen similar symptoms before triggered by both viruses and concussions. 

There are strategies to manage symptoms, such as wearing compression stockings to prevent blood from pooling in the legs while standing. Since the nervous system is intimately involved in digestive processes, such as motility of the intestines and secretion of digestive juices, in people with dysautonomia, we often see irritable bowel syndrome symptoms such as bloating, gas, diarrhea, or constipation. Without proper motility, food ferments in the small intestine, causing an overgrowth of bacteria where it shouldn’t be. Small intestine bacterial overgrowth (SIBO) can cause bloating, constipation or loose stools, as well as brain fog. There are excellent ways to test and treat SIBO through a naturopathic physician trained in this area. 

Brain healing requires a more comprehensive approach because the brain is highly sensitive to what is happening in the rest of the body. Emily started naturopathic medical protocols for dysautonomia include addressing the gut-brain connection through avoiding inflammatory foods, enhancing nutrition, and balancing the microbiome. She took natural medicines to target the mechanisms needed to heal the brain, including enhancing energy production (mitochondrial health), reducing inflammation and oxidative stress, promoting nerve healing, and helping the brain filter toxins. After three months she is feeling much better. Programs can also include hormone balance, stress-reduction training, physical therapy, and visual therapy can all also help address dysautonomia. 

Like most viruses, most people who get COVID make a full recovery. But for those whose lives have been turned upside down after this infection, it’s important for them to understand that there are strategies that can help.

Healing Concussion and Traumatic Brain Injury

The human brain is a remarkable feat of engineering.  But with the consistency of Jello, it is quite vulnerable to damage from injuries.  Every year about 200,000 Canadians suffer concussions.  Sports injuries and car accidents are two common causes of brain injuries, but for seniors, concussions are more likely to be caused by a fall.  The good news is that the brain can recover from minor concussions within a short time. But for multiple concussions or more traumatic brain injuries, the path to recovery can be long and winding.  Post-concussion syndrome can persist for years without the proper help.  Research is showing that there are many ways to enhance healing of the brain. No matter how long it’s been since the brain injury, it’s never too late to jump-start more repair of those delicate structures of the brain that run our mind and body.

Concussions are difficult to diagnose with imagine like an MRI or CT scan, and the symptoms of post-concussion syndrome can be easily attributed to other things.  I often ask my patients about concussions and sometimes find that they do indeed have symptoms of post-concussion syndrome such as:  fatigue, memory loss, cognitive issues, headache, depression, anxiety, irritability, sleep issues, sensitivity to light or sound, issues with sight or hearing, nausea, dizziness and more.

The best approach after a brain injury is to minimize the damage and promote brain healing as soon as possible.  To do that, we have to understand how the brain cells actually get damaged with brain injury.  Then we can use treatments that target those processes. Most medical professionals are not versed in strategies to address what’s really going on in concussion and brain injury, and so these processes are left to damage the brain especially in the critical first few days after concussion.  We need to institute neuroprotection strategies that promote healing, and it’s never too late to start.

Neural inflammation is a significant cause of loss of brain cells, and the connections between them, after head injury.  There are a number of natural products that help to regulate neural inflammation such as curcumin, the DHA portion of fish oil, and green tea. Aerobic exercise also has tremendous benefits to the brain.

We also want to decrease oxidative stress on the brain cells by ingesting higher amounts of anti-oxidant rich foods and medicines.  Berries are rich in antioxidants and Vitamins C and E can be helpful too.

The blood brain barrier (BBB) is intended to only allow certain things to enter the brain from the blood, but after brain injury, there can be a breach in this filtering system.  Toxins then can enter the brain and cause more damage.  Alpha lipoic acid is excellent for healing the BBB and is also an antioxidant.

Mitochondria are the furnaces of the cells, producing needed energy.  The brain cells are particularly dependent on mitochondria for energy. Brain injury can damage the mitochondria and especially lead to brain fog and fatigue.  To heal from brain injury, we need to ramp up the mitochondrial function by taking supplements such as coenzyme Q10, B vitamins as well as eating whole foods and exercising.

We want to stimulate that parts of the brain that can regenerate by enhancing neural stem cells. Humble nutrients like Vitamin D and melatonin can help accomplish these goals.

Promote the lymphatic drainage in the brain called glymphatics. Like a Zamboni clearing the effects of ice skating on an ice rink, the glymphatics of the brain clear away the normal waste products that build up in the brain daily.  This is even more important post brain injury. Sleep is the time when these mechanisms ramp up the most, so I help my concussion patients enhance their sleep.
The nerves of the brain are intimately linked to the chemistry of the digestive system.  Chemicals produced by the gut bugs, or intestinal microbiome, travel to the brain and influence mood, thinking and more.  Having a healthy digestive system will help brain function and naturopathic physicians are an excellent resource for tools to enhance gut health.

Other treatments for concussion are also getting much needed attention.

Brain training can help make new connections in the brain.

The ketogenic diet, while somewhat arduous, has been shown to help a number of brain diseases, including post-concussion syndrome.

Neurofeedback is a sort of visual gym for learning to retrain and re-pattern disrupted brain activity (and is available in Comox).

Functional Neurology practitioners can help target the part of the brain that is malfunctioning and provide specific stimulation to heal those parts.

Cold laser therapy to the skull has demonstrated benefits to many patients at a Toronto clinic and human clinical trials are underway.  This painless treatment has been shown in animal studies to enhance brain healing after traumatic brain injury.  I have treated over 1000 people for various health issues with laser therapy as it helps to gently but quickly regenerate damaged tissue throughout the body.

Reducing electromagnetic fields that may not affect people with healthy brains, but may be one more stress on an injured brain. Turning off wireless at night and removing cordless phones from the bedroom are a good way to start.

There is hope.  No matter how far out from a brain injury, there is always reason for hope.  With the right treatment, people can improve significantly even years after a brain injury if they are willing to invest in their brain health.

There are about seven known mechanisms we can target to help heal a damaged brain.  Neural inflammation is a significant cause of loss of brain cells after head injury.  Oxidative stress on the brain cells damages delicate structures. The blood brain barrier (BBB) is intended to only allow certain things to enter the brain from the blood, but after brain injury, there can be a breach in this filtering system.  Toxins then can enter the brain and cause more damage.  Mitochondria are the furnaces of the nerve cells, producing needed energy.  After brain injury, the mitochondria can’t supply as much energy to the neurons. The brain’s natural healing may be compromised, so we want to stimulate the parts of the brain that can regenerate by enhancing neural stem cells. We need to promote the lymphatic drainage to clear away the normal waste products that build up in the brain daily.  The brain is intimately linked to the digestive system.  Having a healthy digestive system will help brain function.  Naturopathic physicians are trained in methods to address each of these seven mechanisms to enhance brain healing after concussion.
