Can COVID-19 infection cause Alzheimer 's disease? How to treat long-term COVID symptoms of early Alzheimer 's-like disease?
- Long Covid Classified Treatment Options
- 11 Oct, 2022
Numerous studies have confirmed that novel coronavirus infection in humans produced long-lasting side effects even after the symptoms of the initial infection disappeared completely, which we call long-term COVID symptoms. These effects of post-coronavirus remnants mainly were the appearance of brain fog, fatigue, shortness of breath, chronic pain, loss of smell, loss of taste, early symptoms Parkinsonism-like, early symptoms of Alzheimer 's-like disease and diarrhea. These long COVID symptoms can put eternal side effects on the body.
In this paper, the authors studied long-term COVID-19 syndromes, finding that some long-term COVID-19 syndromes were partially early Alzheimer 's-like disease. This article summarized the long-term COVID-19 syndromes of early Alzheimer 's-like disease and gave in-house self assessment to judge whether people developed these symptoms of Alzheimer 's disease. Then, the pathogenesis of symptoms of Alzheimer 's-like disease caused by long-term COVID-19 was analyzed, and the therapeutic ideas of western medicine for the disease after infection with COVID-19 were given.
Due to the limitation of western medicine treatment against long-term COVID-19 symptoms of early Alzheimer 's disease, this paper also recommended some traditional Chinese medicine, including Chinese medicine formula and acupuncture treatment, to treat the related symptoms of early Alzheimer 's disease. In addition, this paper made advises patients with long-term COVID-19 symptoms of early Alzheimer 's disease on taking health care products, as well as on exercise, diet, and sleep. In the end, we hope that the treatment program for long-term COVID symptoms of early Alzheimer 's disease suggested in this paper could benefit patients by improving their symptoms of early Alzheimer 's disease as soon as possible, and even cure theses symptoms caused by novel coronavirus.

1.What are the manifestations of long-term COVID symptoms of early Alzheimer 's disease?
Alzheimer 's disease (AD) is an age-related neurodegenerative disorder that was discovered by Alois Alzheimer in 1907. It is the most common form of dementia and currently affects more than 50 million people worldwide, and this number will increase in the coming decades. Alzheimer 's disease (AD) patients are characterized by progressive and disabling deficits in cognitive function that ultimately lead to impaired quality of daily living.
Pathologically, Alzheimer 's disease (AD) brains are characterized by the deposition of amyloid-beta (Aβ) in senile plaques outside neurons and the formation of neurofibrillary tangles (NFTs) composed of hyperphosphorylated tau (p-tau) in neurons. This leads to loss of synapses and neurodegeneration, ultimately leading to symptoms associated with Alzheimer 's disease (AD). There are two main types of Alzheimer 's disease (AD): early-onset Alzheimer' s disease (EOAD), which usually starts before 65 years of age, and late-onset Alzheimer 's disease (LOAD), which develops after 65 years of age.
Early-onset Alzheimer 's disease (EOAD) forms a minority (5%) of all Alzheimer' s disease (AD) cases and has autosomal dominant inheritance associated with three genes: amyloid precursor (APP), presenilin-1 (PSEN1), and presenilin-2 (PSEN2). In contrast, researchers have not identified specific genes that directly cause late-onset Alzheimer 's disease (LOAD), and several hypotheses have been proposed as the underlying cause. The three most common hypotheses are: the amyloid-beta (Aβ) cascade (chain reaction, enzymatic reaction, or amplification effect) hypothesis; the tau hypothesis; and the neuroinflammation hypothesis.
To date, studies in the treatment of Alzheimer 's disease (AD) have focused on evaluating therapies designed to reduce amyloid-beta (Aβ) or p-Tau protein pathological aggregates or to reduce neuroinflammation. Eisai and Biogen announced that Lecanemab, an Alzheimer 's disease (AD) drug jointly developed by the two sides, has achieved good results in clinical trials for the treatment of patients with mild Alzheimer' s disease and Alzheimer 's disease, resulting in mild cognitive impairment (MCI).
Since the COVID-19 pandemic, many people have been infected with novel coronavirus with a large number of patients with post COVID-19 symptoms have emerged. A small number of people presented with early symptoms of Alzheimer 's disease, which were sometimes continuous, but sometimes intermittent, and usually lasted for a long time, even more than two years. According to the results of large-scale case statistics in the latest study report, people above 70-year-old infected with COVID-19 within a year were 70% more likely to develop Alzheimer's disease than people who didn’t infect with the COVID-19.
From the analysis of clinical cases and the conclusions of medical research papers, it can be seen that novel coronavirus infection can greatly increase the probability of Alzheimer 's disease in humans. Some long-term COVID-19 symptoms coincide with early Alzheimer 's disease symptoms. If the patients infected with the long-term COVID-19 don’t recovered, they are likely to develop Alzheimer 's disease.
According to the published medical papers on long-term COVID-19 symptoms and early Alzheimer 's disease, we concluded that long-term COVID symptoms coincide with early Alzheimer 's symptoms with the following.
(1) Memory loss: feel that one has a cognitive impairment; often unable to remember something; memory loss, forgetfulness; appear symptoms of senile dementia-like.
(2) Language disorders: feel that it is not fluent and smooth when speaking; often forget to choose which words to express meaning. Slurred speech and flat speech tone with monotonous rhythm and no cadence.
(3) Attention disorder: feel that the brain is not in a state and mental trance; feel it is easy to distract and difficult to concentrate.
(4) Get lost: feel the brain often is in the state of vertigo; feel dull in discerning spatial directions.
2.How to judge whether people suffered the long-term COVID-19 symptoms?
What are Post Covid-19 Symptoms (namely: Post Covid-19 Symptoms or Long Covid)? According to the definition of the World Health Organization, Post Covid-19 Symptoms or Long Covid, refers to since the patient was infected with the new coronavirus, the results of his PCR showed positive as criteria, and he still suffers uncomfortable symptoms after 3months. More detailed updated statistical information on the incidence of Post Covid-19 Symptoms according to the timeline can be found in the figure below.
Post Covid-19 Symptoms are mainly concentrated in five aspects, including respiratory syndrome, cognitive system syndrome, chronic fatigue syndrome, chronic pain syndrome, and mental syndrome, such as long-term COVID symptoms of brain fog, which belongs to the cognitive system syndrome. Long-term COVID-19 symptoms of chronic fatigue are one of chronic fatigue syndrome. According to medical classification, the coincident symptoms of long-term COVID-19 symptoms and Alzheimer 's disease should be classified as neurological disorders.
If you have a history of the novel coronavirus, which means your previous result of PCR test showed positive, and before infection with the novel coronavirus, you didn’t suffer from Alzheimer 's disease, but now you are presenting these symptoms of Alzheimer 's disease in the above section, you are likely to afflict by Post Covid-19 Symptoms of early Alzheimer 's disease.
3.What is the relationship between long COVID symptoms and the human immune system?
According to published research papers on long-term COVID-19 symptoms, medical papers on cognitive dysfunction and cranial nerves, we found that long-term COVID symptoms of brain are often associated with immune responses.
Immune response refers to the body 's defense response to foreign components or variant autologous components. Immunoreactions can be divided into non-specific immune responses and specific immune responses. Nonspecific immunity constitutes the first line of defense function of the human body and synergizes and participates in specific immune responses. Specific immune responses may manifest as normal physiological responses, abnormal pathological responses, and immune tolerance. According to different mediators of mediated effector response, specific immune response can be divided into T cell-mediated cellular immune response and B cell-mediated humoral immune response.
According to the published medical papers on cognitive dysfunction in long-term COVID, we concluded that the pathogenesis of symptoms of cognitive dysfunction after long-term COVID-19 infection can be explained according to the following development path:
(1) First, the response of the human immune system to the site of novel coronavirus infection is divided into two stages. In the preliminary stage, the immune system mobilizes macrophages and polymorphonuclear phagocytes (e.g., neutrophils, basophils, eosinophils) to rapidly reach the site of infection to control infection. In the following stages, the immune system of the human body takes about 4 days to establish adaptive immune mechanisms through learning, including T cell-mediated immune mechanisms to solve the infection, and the production B system-mediated antibody to clear the pathogen- the novel coronavirus, so as to prevent reinfection.
(2) Second, because novel coronavirus can easily mutate, so far as more and more coronavirus variants appear, and the ability of immune escape is increasing, this makes the effect decrease when the antigens (HLA) produced by the human immune system to clear novel coronavirus, which means there will be a small number of novel coronavirus immune escape. Novel coronavirus in some patients has not yet been completely cleared, but because the human immune system is suppressing these coronaviruses, leading the content of novel coronavirus too small to make PCR tests negative.
(3) Third, there are trace viruses that escaped in the human body in the long term, which will persistently infect and invade human tissue cells, causing tissue damage. Tissue damage, in turn, triggers chronic inflammation. This chronic inflammation is produced by a persistent immune response, also causing persistent massive cytokine diffusion.
(4) The continuous breakdown of a large number of cytokine proteins can lead to autoimmunity. Autoimmunity refers to the immune response produced by organisms against healthy cells and tissues of their bodies. Any disease caused by this immune abnormality is called autoimmune disease.
(5) The persistence of trace novel coronavirus continues to deteriorate the situation, leading to T cell failure and immune memory defects. Defects in immune memory can make the immune system gradually insensitive to immune pathways that eliminate novel coronavirus, eventually becoming a coexisting state. This condition is characterized by generalized diffuse chronic inflammation. In the long run, the function of body organs and tissues is reduced.
(6) For patients infected with novel coronaries, some people experienced the virus breaking through the blood-brain barrier and invading nerve cells in the brain. Evidence has been found that novel coronavirus triggers neuroinflammation and neurodegeneration in the brain. This condition can further cause metabolic abnormalities in the brain, such as capillary microthrombi in the brain, nerve cell hypoxia in brain, and so on, which may be one of the causes of long-term symptoms of cognitive dysfunction..
(7) Studies have shown that patients infected with novel coronavirus infection can trigger inflammation of the olfactory bulb or even atrophy of the olfactory bulb if the virus further invades epithelial cells in the olfactory bulb, such as capillary epithelial cells, which disrupts the transmission of electrical signals between olfactory neuron cells and mitral neuron cells. If the virus further invades the olfactory brain, it is the part of the limbic system responsible for the logical processing of encoding and decoding olfactory electrical signals. This makes the electrical signals of the olfactory nervous system unable to be normally understood and operationalized by the brain, which is one of the causes of cognitive dysfunction.
4.What are the causes of early Alzheimer 's disease after the COVID-19 infection?
In order to enter host cells, the coronavirus uses the angiotensin-converting enzyme 2 (ACE2) receptor, expression observed in the central nervous system (CNS) besides other things, and, more precisely, in cerebral vessels, monolayer venation from epithelial cells (CP), and neocortical neurons. This expression pattern suggests that the virus may be able to enter the central nervous system.
Published studies have reported that 36.4% of SARS-CoV-2 inpatients presented with neurological symptoms, such as anosmia, headache, disturbance of consciousness, seizures, and stroke. In addition, a study in rhesus monkeys supported the ability of SARS-CoV-2 to enter the central nervous system. After intranasal inoculation of these non-human primates, the virus is able to enter the central nervous system, mainly through the olfactory bulb and spread to functional areas such as the hippocampus. In addition, infection is accompanied by pathological damage such as inflammatory response and neurodegeneration of the central nervous system.
However, since SARS-CoV-2 protein was detected only in very few cells, no viral particles were found in the brains of these rhesus monkeys and no effective replication in vitro appeared to occur in cell lines associated with the central nervous system (CNS). The researchers concluded that SARS-CoV-2 inside the CNS could not effectively infect and replicate. Pathological damage is caused by cytokines in the central nervous system or systemic inflammation. The fact that 142 SARS-CoV-2 replication and infection was inefficient in the central nervous system (CNS) may also explain why controversial results were obtained when SARS-CoV-2 was detected in the brain and cerebrospinal fluid of postmortem COVID-19 patients, that is, viral gene fragments were sometimes detected and viral gene fragments were sometimes undetectable.
The study begins to provide evidence that infected individuals may have an increased risk of Alzheimer 's disease (AD) later in life, or that SARS-CoV-2 infection may lead to accelerated disease development in Alzheimer' s disease (AD) patients.
For example, 33% of COVID-19 patients discharged from hospital had cognitive skills and motor dysfunction in Helms et al. Memory deficits were reported as persistent symptoms in 13% of 129 symptomatic supervised non-hospitalized participants.
Effect of SARS-CoV-2 infection on neuroinflammation
As mentioned above, intranasal vaccination with SARS-CoV-2 induced neuroinflammation in rhesus monkeys.
Inflammatory cell infiltration was detected perivascularly in the hippocampus and medulla oblongata, suggesting SARS-CoV-2 infection induces neuroinflammation. Observed neuroinflammation can be caused by systemic inflammation and/or direct viral invasion of the brain. Yang et al. investigated postmortem brains of COVID-19 patients and observed that genes involved in inflammation (e.g., interferon) and complement pathways were upregulated in a monolayer choroid plexus (CP) epithelial cell.
In addition, a monolayer choroid plexus (CP) epithelial cell signals from epithelial to the cortex. This communication is associated with the complement pathway that signals microglia and the inflammatory pathway that signals glia and neurons. As a result, microglia and astrocytes are activated and contribute to neuroinflammation. Yang et al looked more closely at subsets of microglia and astrocytes in postmortem brains. The gene expression profile of COVID-19-associated microglial subpopulations was observed to overlap with Alzheimer 's disease (AD) -associated microglia, whereas COVID-19-associated astrocyte subpopulations were mainly characterized by increased expression of glial fibrillary acidic protein (GFAP) and inflammatory factors as IFITM3 (interferon-induced transmembrane protein 3, antiviral effect).
In addition, the magnitude of the induced inflammatory response may depend on the genetic background of the patient. Magusali et al. showed that single nucleotide polymorphisms in the OAS1 gene increased the risk of Alzheimer 's disease (AD) development, and that associated variants of this gene were also associated with the severity of COVID-19. The OAS1 gene was expressed in microglia and appeared to be involved in limiting pro-inflammatory responses. Because OAS1 variants were expressed to a lesser extent than their wild-type counterparts, patients carrying OAS1 variants may develop more inflammation, which may make these SARS-CoV-2 infected patients more susceptible to Alzheimer 's disease (AD).
Effect of SARS-CoV-2 infection on amyloid-β (Aβ) accumulation
Yang et al reported increased IFITM3 (interferon-induced transmembrane protein 3, antiviral effect) expression in astrocytes and neurons of SARS-CoV-2 infected individuals, and IFITM3 showed increased amyloid-β40(Aβ40) and amyloid-β42 levels, indicating that the latter also occurs with SARS-CoV-2 infection. The decreased clearance of amyloid-beta (Aβ) clearance may also be due to failure of amyloid-beta (Aβ) -destroying microglia in response to systemic inflammation.
In addition, the interaction between amyloid-β42 and the S protein of SARS-CoV-2 may decrease amyloid-β42 clearance. The latter was demonstrated by Hur using C57BL/6 mice. More precisely, deposition of amyloid-β42 in the blood of these mice was observed when amyloid-β42 was injected intravenously along with the extracellular domain of S protein. In summary, increased amyloid-β (Aβ) production and decreased clearance ultimately lead to increased amyloid-β (Aβ) deposition.
Increased levels of amyloid-β40 (Aβ40) and amyloid-β42 in neuronal extracellular vesicles (EV) were detected in both COVID-19 patients with and without neurological symptoms, further supporting this contention.
Effect of SARS-CoV-2 infection on Tau phosphorylation
Transgenic Alzheimer 's disease (AD) mice showed increased tau pathology following injection of hepatitis virus (MHV) in a human coronavirus model mouse. In addition, hyperphosphorylation of Tau protein was observed in 3D scanned human brain organoids following SARS-CoV-2 infection. Moreover, elevated levels of phosphorylated tau protein were detected in neuron-derived extracellular vesicles (EV) in COVID-19 patients with and without neurological symptoms. This induction of Tau phosphorylation may be caused by pro-inflammatory stimulation of kinases of phosphorylate Tau.
Effect of SARS-CoV-2 infection on neurodegeneration
Finally, neuroinflammation, amyloid-beta (Aβ) accumulation, and tau phosphorylation can lead to neurodegeneration, a process that may also occur in COVID-19 patients. The presence of neurodegeneration was supported by elevated levels of neurofilament (NFL) peptides in cerebrospinal fluid, plasma, and neuronal extracellular vesicles (EV) in COVID-19 patients compared to controls, as well as neurodegeneration observed when SARS-CoV was intranasally inoculated into rhesus monkeys. Coronavirus itself and associated pyroptosis-induced NLRP3 activation could also support the neurodegeneration process.
The combination of the aforementioned Alzheimer 's disease (AD) features with synaptic loss and decreased expression of neurotransmittance-related genes in excitatory neurons (also reported in COVID-19 patients) may lead to persistent clinical Alzheimer' s disease (AD) symptoms. Studies have shown that COVID-19 and Alzheimer 's disease (AD) promote each other, and Alzheimer' s disease (AD) patients may also be more likely to experience severe COVID-19 symptoms. A sign of this claim is that mortality and vulnerability to COVID-19 appear to be higher among people with dementia.
Amyloid-β42 has also been shown to bind to the S1 spike protein of SARS-CoV-2 and the human angiotensin converting enzyme 2 (hACE2) receptor conjugated to human angiotensin converting enzyme 2-Fc (hACE2-Fc). In addition, when immobilized S1 spike protein was first incubated with amyloid-β42 and then with hACE2-Fc, the binding strength of S1 spike protein to hACE2 (human angiotensin converting enzyme 2) increased.
From the above pathological deduction steps, the COVID-19 infection triggered an inflammatory response in the brain, which in turn produced a series of neurodegenerative lesions, which is the cause of long-term COVID-19 symptoms that are early Alzheimer's disease symptoms. Therefore, when we appear long-term COVID-19 symptoms, do not be careless, bur carefully feel their symptoms to judge whether they are as same as early Alzheimer's disease symptoms. If the symptoms are matched, seek medical attention as soon as possible. The earlier Alzheimer 's disease is detected and treated, the easier it is to control the deterioration of the disease and even cure it.
5.How to treat the long-term COVID-19 symptoms of Alzheimer 's-like?
At first, we need to take a thorough physical examination of our bodies, and besides taking routine examinations, we need to do another four examinations.
The first item: do several more PCR tests, and nasal and throat secretions should be dipped enough to check whether the result shows positive. If it shows positive, it means there is still some active novel coronavirus in the body.
The second item: perform a neurological examination. Because neurological symptoms are highly prevalent in patients with long-term COVID, neurological testing is recommended in all patients with long-term COVID. Even if some patients communicate with their physicians, they do not have neurologically uncomfortable feedback. Many patients will report "brain fog", "difficulty concentrating" and "poor memory." Physicians should carefully evaluate the patient 's main symptoms on a case-by-case basis to design a patient' s neurological examination to determine pathophysiology.
If the patient is wealthy, or the physician has suspicious factors in the diagnosis, further in-depth examination is required. For example, it is specifically tested whether the content of p-tau217 protein in blood greatly exceeds the standard of the average person. If it exceeds, it means the patient is in the early stages of Alzheimer's disease.
Following unconventional deeper neurological tests can be performed. For example, to rule out testicular brain injury, physicians are advised to perform functional magnetic resonance imaging MRI of the brain, including functional magnetic resonance imaging MR angiography of the brain. In elderly patients, imaging findings of early abnormal brain changes in Parkinson 's disease, Alzheimer' s disease, or other types of neurodegenerative dementia can be excluded by functional magnetic resonance imaging MRI of the brain.
When patients report memory impairment, it is important to determine whether this memory impairment is caused by infection with COVID-19 or COVID-19 infection worsens pre-existing symptoms. If ischemic or hemorrhagic stroke is observed on functional magnetic resonance imaging MRI of the brain, we must consider medical therapy to prevent recurrent stroke.
Perfusion imaging (single photon emission computed tomography) may also be performed if the patient is wealthy or if the physician suspects the diagnosis. Cerebral perfusion imaging, which is perfusion imaging using CTP and MRP, has become a routine method to examine cerebral blood flow perfusion in stroke patients. Although there is still lack of some evidence that perfusion imaging is an essential test for stroke assessment, many centers have begun to use perfusion imaging to assess cerebral blood flow in patients.
Cerebral perfusion testing may also show non-specific immunity triggers inflammation(innate immunity, which refers to the normal physiological defense function congenitally possessed by the body and can make the corresponding immune response to the invasion of various pathogenic microorganisms and foreign bodies. ), which is characterized by hypoperfusion in the prefrontal or temporal lobes. Although there is no established treatment for this problem, some drugs that improve brain blood may help improve the condition.
Third item: in addition to basic blood tests, we assessed thyroid hormones, zinc, ferritin, antinuclear antibodies, rheumatoid factor, and blood sedimentation rate in almost all patients. Patients with PASC may have electrolyte disturbances, anemia, thrombocytopenia, hypoalbuminemia, lipid abnormalities, and abnormal glucose metabolism. These data need to be combined with patient symptom descriptions to carefully analyze the pathogenesis behind reasoning to determine whether abnormal laboratory test results can explain the symptoms of PASC.
The fourth item: listen to the sounds of the heart and respiratory system with a stethoscope. Anemia, the signs of heart failure, latent arrhythmias such as atrial fibrillation, and pneumonitis from enteritis must be assessed when abnormal sounds are detected, or if breathlessness persists, and to check whether oxygen saturation decreases during exercise.
The following items, from item 5 to item 7, are required when the patient presents other symptoms.
Fifth item: rheumatoid arthritis or other related diseases must be analyzed when patients have symptoms of joint discomfort.
Sixth item: when the patient complains hair loss, we examine the scalp, return to the history of hair loss symptoms, and confirm the weekly amount of hair loss.
Seventh item: neuropsychological tests should also be performed if the patient has significant psychological problems.
Then, the results of the above comprehensive physical examination and four special examinations should be handed over to the doctor, and then the person should communicate with the doctor to describe one’s own long-term COVID symptoms of parkinsonism-like in detail.
The rough ideas for designing the treatment plan are as follows:
(1) According to the results of the patient's comprehensive physical examination and four special examinations as well as the communication with the patient, find out the most likely pathogenesis of the patient's long-term COVID symptoms of Alzheimer 's-like.
(2) Prescriptions are prescribed for treatment according to the pathogenesis and the patient 's physical condition. In most cases, the brain is found to be slightly inflamed, and at this time, treatments against neuroinflammation are usually used.
(3) For the main direction of medication, if novel coronavirus remains in the body, antiviral drugs such as Paxlovid should be used as a priority. If there is no virus in the body, the drug is used from the perspective of reducing or eliminating the chronic inflammation of the patient, improving the metabolic circulation and immune system of patients. For example, rintatolimod (immunomodulator) and coenzyme Q10 + NADH (mitochondrial modulator) can be used to improve the immune system of patients.
(4) If Alzheimer 's disease are diagnosed, Lecanemab is needed to control the development of the disease. Eisai and Biogen announced that Lecanemab, an Alzheimer 's disease (AD) drug jointly developed by the two sides, has achieved good results in clinical trials for the treatment of patients with mild Alzheimer' s disease and Alzheimer 's disease, resulting in mild cognitive impairment (MCI).
(5) Massage of the brain can also be tried, and studies have shown that this is also beneficial for recovery.
6. How to treat long-term COVID symptoms of Alzheimer 's-like from a traditional Chinese medicine(TCM) perspective?
From the theory of syndrome differentiation and treatment of TCM, the treatment of long-term COVID-19 symptoms of Alzheimer 's-like can obtain more accurate TCM syndrome differentiation and more suitable TCM formulas from the following three steps.
(1) Perform the observation, smelling, hearing, and inquiring of traditional Chinese medicine diagnosis, and consult the comprehensive physical examination report and four special examination reports of western medicine in the previous section at the same time. Only in this way can TCM doctors obtain the most detailed disease information of patients to support them to make the most accurate syndrome differentiation and treatment of patients' conditions.
(2) TCM doctors will classify and summarize the main symptoms, accompanying secondary symptoms, physical condition, and sick parts of the internal organs of the patients according to the most comprehensive disease information of the patients. First, the main symptoms are the most unbearable symptoms of patients at present, such as Alzheimer 's-like. Second, accompanying secondary symptoms are that suffered from the main symptoms, which means the patient is experiencing other uncomfortable symptoms, such as mental turbidity, chronic headache and so on. Third, to find out the physical condition of the patient, which means the patient's current physical health status, belongs to which category in the TCM constitution. For example, yang-deficiency constitution, phlegm-dampness constitution, qi-deficiency constitution, blood stasis constitution, etc.
(3) TCM doctors, according to the above summary, combined with the internal organs and meridians related to symptoms, comprehensively use the theory and practical experience of TCM to make TCM prescriptions for patients. If acupuncture and moxibustion are required, these programs will also be prescribed.
Traditional Chinese medicine (TCM) theory is mainly based on: Zhang Zhongjing’s “Treatise on Febrile Diseases”, “Synopsis of Golden Chamber”, Huang Yuanyu's “Four Sacred Hearts Source”, “Typhoid Fever Suspension”, “Jinkui Suspension”, “Changsha Yao Jie”, Li Dongyuan 's “Treatise on the Spleen & Stomach”, and Zhang Jingyue' s “Jingyue Quanshu”.
TCM Practical experience, which can be found in Google Scholar (Fig. https://scholar.google.com/), and search for keywords for TCM treatment of long-term novel coronavirus symptoms. For example， COVID-19 Traditional Chinese Medicine, Long Covid Traditional Chinese Medicine. A large number of academic papers on medical research on the treatment of Long Covid by traditional Chinese medicine can be found in this way.
