What Are The Clinical Manifestations Of Long COVID Headache?
At present, it has become customary in the medical community to classify chronic headache caused by COVID-19 infection as Long COVID brain fog. According to statistics in the study report, chronic headache patients accounted for a quarter of the overall long COVID brain fog patients. That means about 0.25% of people infected with COVID-19 will experience chronic headaches. According to published medical papers on long-term COVID chronic headache, we conclude that the manifestations of chronic headache are as follows:
(1) Chronic Migraine: feel chronic headache throughout the brain, or symmetrical chronic headache bilaterally in the brain. Sometimes there is rhythmic throbbing pain in sensation.
(2)Chronic tension headache: frequently feel hot head and tightness of head. Some people present with tension headache. Someone may feel like the squeezed brain or tightened brain muscles.
(3)Accompanying symptoms, brain fatigue: feel drowsy, it’s easy for brain to feel tired, feel fatigued when thinking, it’s easy to feel sleepy when reading, feel sleepy in the daytime.
(4)Accompanying symptoms, dizziness: feel a false sense of movement or rotation, vertigo, feel lightheaded, unstable to stand or walk, and likely to loss balance and fall.
(5)Accompanying symptoms, loss of smell: olfactory dysfunction, feel that one can not smell anything through the nose, or that the smell is abnormal.

Telemedicine may be a breakthrough given the large number of long COVID-19 patients and the scarcity of available medical resources

More than 1.07 million Americans have died from COVID-19 pneumonia since the outbreak, ranking highest in the world, according to data released by Johns Hopkins University on November 25. Additionally, more than 98 million people worldwide have been affected. The ultra-strong transmission of new subtype strains is expected to cause more than a third of Americans to become infected with COVID-19 by the start of next year, and about one-fifth of these infected people may develop "Long COVID" by the end of the year.
On November 21, the U.S. Department of Health and Human Services (HHS) issued a report, recommending that public places in the United States force or advise people to wear masks and maintain social distance to prevent injuries caused by “Long COVID".
Post COVID-19 symptoms are known as “Long COVID." According to the World Health Organization, "Long COVID" refers to symptoms that persist for at least two months after 3 months following the infection with COVID-19 and that cannot be attributed to any other illness.
According to a report released by the U.S. Department of Health and Human Services (HHS), "Long COVID" can cause more than 50 diseases that can affect almost all organ systems including the lungs, heart, and brain systems. Brain fog, headache, vertigo, sleep disorders, etc., are common symptoms of Long COVID. The most common symptoms include fatigue, haze, dyspnea, and memory loss.

How Long Will Symptoms Of Brain Fog Last After Being Infected With Covid-19?

In 2021, in a study designed to describe long COVID symptoms in more than 3,000 people from 56 countries, researchers found that 88% of respondents represented brain fog symptoms such as cognitive or memory problems. During the first few months after the onset of COVID-19, these symptoms showed an increasing trend and then started to decrease gradually. At the beginning of the 7th month after the onset of COVID-19, 55.5% of respondents reported suffering from cognitive problems such as brain fog.

In another study in 2021, patients with brain fog caused by long-term COVID were asked to describe their experiences. As in the previous study, most participants reported brain fog in the first few months following the onset of COVID-19. Participants were followed up by email for 4 to 6 months after the initial assessment. Of those who responded to follow-up, 65% people felt that their symptoms of brain fog were gradually improving.

A 2022 study investigated the rehabilitation of individuals with neurological symptoms such as long-term COVID and brain fog. The mean duration of brain fog since participants developed symptoms of COVID-19 infection was 14.8 months. After an initial evaluation, participants were followed up for 6 to 9 months. During follow-up, no significant changes were observed in the reporting of brain fog symptoms compared with the initial assessment, which means there were no significant change among most patients with brain fog. Researchers pointed out that quality of life measures of study participants remained lower than that of the general population.

According to published medical statistics papers on long COVID brain fog, the symptoms could last for quite a long time. The symptoms of brain fog tends to peak within a few months of infection with COVID-19 and them generally improve over time. Recent studies have found that brain fog symptoms may last more than a year after infection with COVID-19. Moreover, studies have shown that more than 20% of patients with long COVID brain fog still did not get an improvement for their symptoms after a year.

Memory loss! Many COVID-19 patients remain cognitively impaired months after recovery.

According to a report by the National Broadcasting Corporation (NBC) on the 23rd, a new study shows that many people who recover from the new coronavirus infection still have cognitive impairment more than seven months later.

The study, which describes a variety of cognitive problems experienced by patients treated at New York's Mount Sinai hospital system, provides further evidence that "long-term carriers" of the new coronavirus recover weeks or months after initial illness , may also have a large number of symptoms.

As many as 24 percent of COVID-19 patients recover with some sort of cognitive difficulty, researchers from the Icahn School of Medicine at Mount Sinai report in the journal JAMA Network Open on Friday. , including problems with memory, multitasking, processing speed, and concentration.

Jacqueline Becker, a clinical neuropsychologist at the School of Medicine and study author, said: "We found long-term cognitive impairment across age groups and disease severity. "

The report pointed out that Mount Sinai is one of the largest hospital systems in New York, and the institution has been treating patients with new coronary pneumonia since the early days of the epidemic. For the study, 740 patients enrolled at the hospital were aged 18 or older, spoke English or Spanish, tested positive for COVID-19, and had no history of amnesia. Tested during May. The results showed that a relatively high proportion of patients remained cognitively impaired 7.6 months after onset.

The most common (affecting nearly a quarter of patients) were reported to be problems with recent memory, followed by recall problems. Other reported phenomena include a decline in processing speed and ability to perform functions.

Similar complications have emerged at other hospitals. At Northwestern Medical Center, some patients with COVID-19 end up with such severe cognitive decline that they don't respond well after they are discharged Inability to take care of themselves.

Helen Lavretsky, a professor of psychiatry and director of the UCLA COVID-19 Pandemic Clinic, said that when you see patients in their 20s, 30s and 40s with severe mental deficits, "it's overwhelming." Heartbreaking." Some patients say: "They can't work; they can't think; their memory is damaged; they get confused when they drive somewhere because they don't know how they got there."

While there have been reports that vaccination can help long-term carriers of the new coronavirus, UCLA has produced mixed results, Raftzky said. Some people's symptoms eased after the vaccine, while others stayed the same or got worse.

NBC noted that the scale of the problem is enormous. There have been more than 45 million confirmed cases of coronavirus infection in the United States. While most infected people recover within weeks, huge numbers of people are still dealing with lingering symptoms.

What are the manifestations of long covid dizziness?
A large proportion of long-term COVID-19 symptoms are associated with neurological symptoms, and some medical communities use a folk colloquial vocabulary’brain fog’to facilitate the unified classification and description of post COVID-19 symptoms associated with the brain. Brain fog has not previously been regarded as a medical or scientific term, but rather a colloquial description of a state in which people cannot think normally and clearly when they develop influenza or other diseases. Ordinary people use the fog in their brains to describe problems arising in their usual cognition or thinking, such as dizziness, tinnitus, difficulty concentrating, memory loss, slower thinking speed, inability to think keenly without creativity, and difficulty formulating plans.

During rehabilitation following COVID-19 illness, many patients said they experienced "brain fog". According to figures given in the study report, about 10% of patients infected with COVID-19 will experience long-term COVID-19 symptoms. At present, it has become customary in the medical community to classify the symptoms of dizziness and tinnitus caused by COVID-19 infection as long COVID brain fog. According to the statistics in the study report, up to 60% of patients with long-term COVID-19 had some degree of dizziness or vertigo, and up to 30% had some degree of tinnitus. And dizziness, vertigo, tinnitus, the three symptoms have a very high degree of coincidence.

According to the published medical papers on the symptoms of long-term COVID-19 of dizziness, we concluded clinical manifestations of dizziness as follows:

(1) Dizziness: feel a false sense of movement or rotation, vertigo, feel lightheaded, unstable to stand or walk, and likely to lose balance and fall.

(2) Blurry vision: blurred vision is found in the morning, and if look at the computer and mobile phone screen for a slightly longer time, feel that vision is trance and eyes are tired.

(3) Tinnitus: refers to the condition in which the external environment does not make a sound, but feels to hear a certain noise, feels that the ear is blocked by cotton, over-high internal pressure,buzzing,and it’s easy to be anxious or difficult to concentrate.

(4) Common accompanying symptoms, brain fatigue: feel drowsy, it’s easy for brain to feel tired, feel fatigued when thinking,it’s easy to feel sleepy when reading, feel sleepy in the daytime.

(5) Common accompanying symptoms, chronic headache: feel symmetrical chronic headache bilaterally on the head; often feel hot on the head and tightness on the head.

Inner ear problems that lead to dizziness (vertigo) are usually related to the person 's brain, eyes, inner ear, sensory nerves, which are input systems for the sense of balance in the human body.

(1) Brain is used to automatically calculate the sense of balance of the human body.
(2) Eyes help people determine the position of the body in space and its mode of movement.
(3) Sensory nerves send information to the brain about the motor state and position of various parts of the body.
(4) Inner ears with built-in sensor can detect gravity and anteroposterior movement.

Vertigo is an illusion that makes you feel as if surroundings are spinning or moving. When suffering from inner ear disease, your brain receives signals from the inner ear that are different from those received by your eyes and sensory nerves. Vertigo is the result of your brain dealing with confusion. The usual causes of vertigo are the following:

(1) Benign paroxysmal positional vertigo (BPPV). The disease leads you to have a strong and brief illusion that you are rotating or moving. Seizures are caused by rapid changes in head movement, such as turning over in bed, sitting up, or getting a heavy blow to your head. BPPV is the most common cause of vertigo.

(2) Infection. A viral vestibular nerve infection called vestibular neuritis can cause severe persistent vertigo. If you also have sudden hearing loss, you may have labyrinthitis.

(3) Meniere 's disease. This disease presents with excessive accumulation of fluid in the inner ear. It is characterized by a sudden onset of vertigo that lasts for hours. You may also have fluctuating hypoacusis, tinnitus, and blockage of your ears.

(4) Migraine. Even people who have migraines do not have severe headaches, they may experience vertigo or other types of dizziness. Such episodes of vertigo may last from minutes to hours and may be associated with headache and sensitivity to light and noise.

Causing dizziness is also associated with problems with your body 's blood circulation system, and if your heart does not pump enough blood to your brain, you may feel dizzy, weak, or unable to maintain balance. For example:

(1) Blood pressure decreased. A sharp drop in systolic blood pressure (the larger of your blood pressure reading) can cause a brief feeling of dizziness or lightheadedness. This may occur when sitting up or standing up too quickly. This condition is called orthostatic hypotension.

(2) Poor blood circulation. Cardiomyopathy, heart attack, irregular heartbeat, and transient ischemic attack can all cause dizziness. In addition, decreased blood flow may lead to insufficient blood supply to the brain and inner ear.

Causing dizziness is also associated with problems with the nervous system of the body, such as the following:

(1) Neurological disorders. Neurological conditions such as Parkinson 's disease and multiple sclerosis may lead to progressive loss of balance. Can cause dizziness.

(2) Drugs. Certain medications (such as antiepileptics, antidepressants, sedatives, and tranquilizers) may cause side effects such as dizziness. In particular, blood pressure medications can cause fainting if blood pressure drops too low.

(3) Anxiety disorder. Certain anxiety disorders cause lightheadedness or dizziness, often called dizziness. These disorders include panic attacks and fear of leaving home or staying in an empty large square (agoraphobia).

(4) Low iron content (anemia). If anaemic, dizziness may occur with other signs and symptoms, including fatigue, weakness, and pallor.

(5) Low blood glucose levels (hypoglycemia). This condition usually occurs in diabetic patients taking insulin. Dizziness (lightheadedness) may be accompanied by sweating and anxiety.

(6) Carbon monoxide poisoning. Symptoms of carbon monoxide poisoning are usually described as "flu-like" and include headache, dizziness, weakness, stomach discomfort, vomiting, chest pain, and confusion.

(7) Overheating and dehydration. You may get dizzy from overheating (hyperthermia) or dehydration if you join activities or drink too little water in hot weather. This is especially true when you take certain heart medicines.

In this paper, from the perspective of COVID-19 infection, we simply analyze why COVID-19 infection will cause a large number of people suffering from long covid dizziness, vertigo and tinnitus.

How To Treat Long-Term COVID Chronic Headache Symptoms?

Chronic headache of Long COVID is more prevalent in middle-aged women, accompanied by long-term COVID symptoms such as fatigue, cognitive dysfunction, and dizziness, as well as hyposmia and insomnia or other sleep disturbances. Cross-sectional studies have shown that the topography of headache is predominantly bilateral, predominantly frontal or periocular, and compressive.

The chronic headache phenotype is highly variable, occurring mostly in the temporal and occipital lobes, and often changes according to the pulse rhythm occur in approximately one-third of patients. Headache of Long COVID often mimic the primary headache phenotype. The two most common phenotypes described are tension-type headache and migraine-like headache.

Migraine-like headache may be associated with nausea, vomiting, photophobia, and phonophobia and exacerbated by daily physical activity, whereas tension-type headache is not exacerbated by daily physical activity and rarely associated with other symptoms.

Patients with a history of headache commonly report worsening headache. Tension-type and migraine-like headache features can also be seen in patients who have no personal history of headache or who have not experienced headache in the acute infection phase.

For people with more severe symptoms of chronic headaches, the ideas of designing treatment options are roughly:

(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 chronic headaches, namely exploring the reason.

(2) Prescriptions are prescribed for treatment according to the pathogenesis and the patient's physical condition.

(3) For the main direction of medication, if COVID-19 remains in the body, antiviral drugs such as Paxlovid are used first. If there is no virus in the body, medication is decided by specific manifestations of symptoms. For example, if people suffer from a mild occasional chronic headache, they can try to take over-the-counter aspirin and Tylenol. Over-the-counter pain medications such as ibuprofen (Advil) and acetaminophen (Tylenol) may also be taken. For chronic tension-type headache, which is the feeling of excessive pressure or tightness in the head, non-steroidal anti-inflammatory drugs (NSAIDs) are the first choice for acute treatment, followed by combination agents including caffeine. Try taking low doses of over-the-counter medications to relieve seizures, soothe blood pressure, and relieve depression. If there is an inflammatory reaction, patients can take some anti-inflammatory drugs such as indomethacin.

(4) For the symptoms that affect the working life of patients, some drugs for the improvement of symptom experience, such as brain strengthening, refreshing, stimulating nerves, and other effects, can also be used according to specific symptoms. Low doses of amitriptyline have been shown to be more effective in patients with post-COVID-19 symptoms of chronic headaches.

(5) Hot or cold compresses can be beneficial if people present with tension headaches. Apply this method on your neck for about 15 to 20 minutes. Oxygen therapy and physical brain massage can also be tried, and studies have shown that these two methods are also beneficial in reducing headache.

(6)If patients suffer from psychiatric symptoms such as insomnia, anxiety, and depression, they should seek help from psychologists and herbalists to eliminate these psychological symptoms. This is also helpful in removing long-term COVID-19 symptoms of chronic headaches.

We should follow this figure to reason when diagnosing chronic headache of Long COVID:

From Infection to Healing——Jed's experience about Long COVID
Jed, a Long COVID patient, contacted LongCovidCareCenter.org and said: "Before the epidemic, his life was very full. Jed is a 32-year-old bank worker from London. He often went to the gym twice a week. But his peaceful life was broken in the early morning of November 15. When Jed returned home from a day's work, he felt that something was wrong with him. He said: "I feel very scared . I started feeling hot and cold and I kept coughing and coughing and coughing and I didn't know what was wrong with me."

When Jed checked into the hospital, he told LongCovidCareCenter.org his doctor said he was suffering from post-COVID fatigue. There is no specific treatment plan for this symptom, so the doctor only gave him some suggestions for improvement, such as: you can give priority to important things at ordinary times. Master the rhythm of doing things well, and don't be too impatient, which can improve the quality of life after illness and stabilize his health. But Jed is having trouble understanding how to apply the concept of same pace to his life. Keeping the same pace of doing things was nearly impossible, as she would often wake up exhausted and then fall back asleep.

"When I spoke to the doctor about my dizziness, about my fatigue, he said he didn't know how to treat it, he hadn't found a cure yet. I felt worse and if the doctor couldn't help, who could ? busy," he said.

By chance, Jed noticed the LongCovidCareCenter.org platform through an article reposted by a friend, and he carefully browsed the articles published on this platform. Some articles published on this platform about Long COVID are very helpful for him to understand his own symptoms. thinks this platform is very professional. He found that there are online doctors on this platform, maybe the doctors on this platform and the doctors in the hospital Not the same, maybe they can help him, so he clicked on the LongCovidCareCenter.org platform to contact a doctor online for consultation.

The online doctor on this platform first asked Jed about his symptoms, the number of times he was fatigued every day, how long each time would last, and how his fatigue felt. Jed told the online doctor about his illness During the process, he went to the hospital for consultation, but after the treatment failed, he could only treat and recover at home.
Through Jed's description, the online doctor learned the cause of his illness and some of his symptoms, and made a preliminary diagnosis of his symptoms. The online doctor then asked about Jed's treatment plan and medication when he was infected with covid-19, his previous Disease history and allergy history, as well as some of Jed's physical conditions at the time, so as to provide a basis for diagnosing whether Jed was mild or severe COVID-19 sequelae.

After Dr. LongCovidCareCenter.org learned about Jed's physical information, he explained to Jed the pathogenesis of his Long COVID in detail, and he explained to Jed why sequelae cognitive impairment and fatigue appeared after he recovered from COVID-19 and other symptoms. Jed's physical condition with other background experts of LongCovidCareCenter.org. They need to know which type of Long COVID Jed has, and judge Jed's physical fitness according to his physical condition. Finally, according to Jed's symptoms and Personalized treatment plan tailored .

After a while, the online doctor replied to Jed and prescribed a treatment plan for him. He sent Jed a prescription, which was very detailed and included the treatment methods. Of course, there are also some medicines, Chinese patent medicines and Western medicine prescriptions , which specifically mark the dosage and precautions of the medicines. In addition, there are also some health care products listed, including moxibustion instruments and essential oil patches. It also includes some suggestions on life and diet, hen this prescription is very presive.com

So Jed took the medicine carefully according to the medication instructions on the prescription every day, and used it together with the moxibustion instrument and essential oil patch every day. The moxibustion instrument was used to heat the painful parts of the body, and the essential oil patch was used to apply the head. After following this treatment method for a period of time, Jed felt that his memory was slowly recovering, and his body pain and fatigue had also been greatly improved, allowing him to have a new life, which he felt was full of hope. He believes that as long as he insists on taking it, the Long COVID will disappear.

Jed has found a cure for Long COVID, and his body and life are slowly getting back on track. We are sincerely happy for him.

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.
