Treatment for Covid-19 Long-Hauler Symptoms

Mental confusion, fatigue and smell blindness are frequently reported in covid 19 survivors long after the virus has been eradicated (1). Clinics in the San Francisco Bay Area report success clearing brain fog, fatigue and other post covid symptoms with LENS neurofeedback treatments. This technology has been in use for decades but is not widely known. One treatment session typically restores clarity, lost senses, and stamina. Multiple sessions provide enduring relief. The Echo Neuro protocol has been used widely to treat anxiety, PTSD, migraines, and ADHD, but has now demonstrated effectiveness at restoring full functioning after any virus or medical procedure.  


After effects(sequelae) of COVID-19 remain in 32.7% of cases six months after infection (2). They are so common that the World Health Organization (WHO) created a new medical diagnostic code, U09.9, to be used in cases where patients are suffering from either residual or brand-new post-COVID-19 conditions despite having no evidence of an acute infection (3). One study has found that residual brain immune cell (microglial) activation observed in the majority of COVID patients is not caused by a viral infection of brain tissue, but rather from systemic inflammation (4).


Inflammation is the cause of neurological symptoms

The major brain science breakthrough of the 2010’s was the discovery of the brain’s inherent immune system and how it communicates directly with the gut (the real brain) and its immune system. When the mind senses emotional distress, stress signals are activated throughout the body causing over 25% of the body’s energy to be consumed in seconds. Once this fear response becomes habituated, inflammation begins spreading rapidly throughout the body making it near impossible for the mind to dismantle negative neural pathway alarms and shut down the constant firing off of a flight-or-flight stress response. 

Clinical studies are now supporting the concept that any surgery or life-threatening viral infection is perceived by the brain as trauma. This can lead to long-standing inflammation of microglial cells and defensive trauma memories/neurological symptoms post-infection such as brain fog, fatigue, headache, indecision, moodiness, fear, anxiety (5). Echo Neurotherapy protocols utilizing passive EEG treatment (also referred as LENS neurofeedback) specifically targets brain inflammation and helps rebuild healthy neural pathways. Clinical studies have shown patients of all ages feeling calmer with more cognitive clarity, mental agility, emotional steadiness and resilience after just one session of LENS neurofeedback. As normal thought processing pathways are being re-established throughout the mind and body, LENS neurofeedback has been clinically demonstrated in over a million sessions conducted worldwide over thirty years to reduce brain fog, pain and enhance sleep quality and memory in patients suffering from lingering symptoms caused by traumatic brain injuries, adverse childhood emotional experiences, surgeries, and/or infections. 

This passive EEG treatment provides external electrical stimulation to the brain to stop overfiring of negative thoughts and defensive physical reactions. Typically the most energy-wasting neural pathways are addressed first with positive results noted within minutes to days of treatment. Multiple sessions may be required to unlock enduring benefits which extend out for months by restoring healthy mental functioning and decreasing systemic inflammation. 


Clearing chronic cold and flu symptoms with neurofeedback

LENS neurofeedback treatment can be very effective at supporting the immune system for those suffering from lingering or recurrent cold or flu symptoms. It is also not uncommon during the first few weeks of treatment for overstimulation of the immune system to trigger cold-like symptoms; this means neurofeedback is working and stirring up a positive response inside the body. Clients can trust their brain to prioritize what order of healing is best for them because treating the worst first improves the likelihood of success with the body’s total load of inflammatory symptoms. 


Case History Regarding Post-Viral Cognitive Impairment and Smell Blindness (hyposmia):

At age 19, Peter was struck down by the pandemic. Returning to work after three weeks, his supervisors told him he was slow and ineffective. He himself didn’t realize he had a problem and was covering up his cognitive difficulties. Everyone in his life was telling Peter he wasn’t acting like his best self. 

Peter thought, “[This virus] has been the worst illness of my life. It caused me to feel so bad that I couldn’t get out of bed for weeks. My main symptoms were headaches, sore throat, and body ache, as well as ongoing fatigue. I have no sense of smell or taste now. Recovery has been slow and even after months, I just can’t get back to my old self. Thinking and moving at the same time seem near impossible. Am I a “long hauler” where I may have symptoms for years after the virus is gone?!”

After Peter’s first feedback of LENS Neurofeedback, he immediately felt his : My energy increase. He became more aware of his thoughts and felt like his mind was starting to clear up. “I can pay attention to every word I hear. Information is sticking! My old me is coming back!” 

LENS Neurotherapy was something Peter had never heard about but was very curious to experience and so continued care thereafter. After his second session, his brain fog and generalized fatigue were gone. (Not improved; GONE!) Peter was amazed to feel like his mind and body were finally back in sync. He felt more energetic and focused; things just kept feeling better and better every day thereafter.
