Can a cold cause encephalitis? What are the symptoms of encephalitis caused by a viral flu?

Encephalitis can be caused by colds, most commonly viral encephalitis, but not all people with colds develop encephalitis, and encephalitis is often rare. Whether a cold will cause encephalitis depends on the route of infection, one of the ways is the blood pathway, there is a natural barrier in the brain tissue to prevent external infections from entering the brain tissue, called the blood-brain barrier, after a cold, as long as the blood-brain barrier function is normal, viruses or bacteria enter the blood, reaching the blood-brain barrier will be blocked, unable to cause encephalitis. However, if the patient has experienced hypoxia or trauma in the past, causing the blood-brain barrier to be damaged, then once the patient catches a cold, the pathogen will enter the blood-brain barrier and reach the brain tissue, causing encephalitis.

There is another pathway that is less common, and there is a special structure in the brain tissue called the trigeminal nerve semilunar node. In the process of growing up, they are generally exposed to herpes simplex virus, these herpes viruses will be latent in the trigeminal nerve meniscus, after a cold the body's immunity decreases, these viruses will replicate in large quantities, and retrograde along the trigeminal nerve meniscus into the brain tissue, causing herpes simplex encephalitis. Therefore, in the event of a cold, do not ignore the symptoms of the cold, you should be in a timely manner, if there is a persistent headache, fever or even nausea and vomiting after a cold, you should be alert to the symptoms of encephalitis, and you should go to the hospital in time for treatment.

If it is a simple cold, it will not cause encephalitis, but if there is a fever, then pay attention, often fever can cause encephalitis.

Colds generally do not cause encephalitis, when you have a cold, you must drink more boiled water, keep enough sleep, take a little cold medicine, if the symptoms still do not change, you should go to the hospital in time**.

Colds can cause encephalitis, colds may be caused by bacterial or viral infections, if not in time, the inflammation may spread to other parts, easy to cause viral encephalitis, but not all patients will cause encephalitis, as long as the cold in time can avoid other complications. Encephalitis should also be carried out in a timely manner**, but hospitalization** must be carried out to avoid other complications.

Direct infections, such as severe head trauma, ear, nasopharynx, and tooth infections.

Meningitis coughs and sneezes are also contagious, so if you are around someone with meningitis, you are at high risk of being infected, so avoid kissing them, sharing utensils or toothbrushes.

Colds can cause encephalitis, but not all colds can cause encephalitis. If the cold is severe, the ability to resist the disease is reduced, the virus replicates in large quantities, and retrograde into the brain tissue will cause encephalitis; When the blood-brain barrier is disrupted, pathogens can also enter brain tissue and cause encephalitis.

In general, the common cold does not cause encephalitis, but it is possible if it is a viral or bacterial infection that causes a fever.

Colds generally cause encephalitis, because if the fever is particularly severe, it can be easy to get encephalitis.

Can you have a cold that causes encephalitis? I think a cold can cause encephalitis.

Introduction: If a child has encephalitis caused by the virus, he may have fever and runny nose at the beginning. If the fever is too long, there may be a rash on the surface, and as the body temperature rises, it will also be accompanied by vomiting, diarrhea and cough.

However, the symptoms of encephalitis vary from mild to severe, and the way of manifestation is also different, at present, it is mainly manifested as mental abnormalities, such as headache, vomiting, drowsiness, coma, and some will also show irritability, crying, insomnia, hallucinations, decreased activity, loss of appetite, etc.

Viral encephalitis is caused by the baby after being infected with a cold, because the germs enter the body to infect the disease, generally through the respiratory tract or digestive system into the human body, especially in the spring is the most likely to occur, once the human body's immunity declines, the virus will enter the human brain through the blood to cause disease, and viral encephalitis generally occurs in children and young children, because the child's immunity is relatively weak, and their awareness of protection is relatively poor.

If you want to prevent encephalitis, you must first develop a good personal hygiene habit, parents must let their children wash their hands before meals, and usually pay attention to cleaning and disinfection of the child's living environment, and often take out the child's quilt clothes to dry, so as to avoid encephalitis caused by the virus in the baby due to environmental problems. Usually also work and rest on time, avoid overwork, ensure rest, participate in more outdoor sports, improve the child's own immune system, so as to better prevent the occurrence of diseases, usually let the child drink more water, the diet is mainly light, you can eat more fresh vegetables and fruits, so that the body can be better.

Finally, when children are young, their resistance will be relatively poor, so at this time, parents should vaccinate their children in time, these vaccines can prevent children from contracting the virus and causing encephalitis.

The symptoms of pediatric viral encephalitis, the clinical manifestations of acute viral encephalitis caused by various viruses vary greatly, and it is determined by the following aspects: the first is that the part of the nervous system is different; The second is the intensity of the virus's pathogenicity; The third is the child's immune response.

Therefore, even in children infected with the same virus, the clinical manifestations are different. Its clinical manifestations are mainly manifested in two parts: the first part is the symptoms of the previous stage.

Symptoms of the upper respiratory tract or digestive tract, such as fever, headache, sore throat, vomiting, diarrhea, loss of appetite, etc.

The second part is neuropsychiatric symptoms. Clause.

First, it is a disorder of consciousness. Mild cases are indifferent, sluggish, irritable, and drowsy to the outside world, and severe cases may have delirium and coma. Clause.

2. Increased intracranial pressure.

Elevated intracranial pressure may cause headache, vomiting, dizziness, brain herniation, and full bregma in infants. Clause.

3. Convulsions. Can be localized or generalized. Clause.

4. Motor dysfunction.

Depending on the site of injury, it can manifest as central and peripheral paralysis of one side or one limb, that is, it manifests as extrapyramidal movement disorders such as chorea, muscle rigidity; cranial nerve palsy with strabismus; Facial paralysis or dysphagia, etc.

Clause. Fifth, it is a mental disorder. Such as memory loss, disorientation, auditory and visual hallucinations, mood changes, irritability, and sometimes suspicion.

Shock may occur, sore throat, fever, vomiting, general weakness, or blurred vision.

Encephalitis caused by the virus in children will cause symptoms such as persistent high fever, vomiting, convulsions, convulsions, and coma.

Introduction: Encephalitis caused by viruses can manifest as respiratory infections in the early stage, such as fever, headache, vomiting, diarrhea, etc. If the disease progresses rapidly, it will cause the patient to have mental symptoms, such as impaired consciousness, dullness and irritability in mild cases, coma and syncope in severe cases.

Some can cause headaches, vomiting, dizziness, and in severe cases, respiratory failure. Some can also cause symptoms such as epilepsy, hemiplegia, numbness, and convulsions.

The main cause of viral encephalitis is an acute reaction caused by viral invasion. Once the virus invades the human body, it invades the human brain through nerve cells, thus causing inflammation, which is similar to other diseases at the beginning, such as fever and headache, and then neurological symptoms, which will generally heal naturally, but a few people will cause more serious nerve damage. If you want to **encephalitis, it is generally through physical cooling, a few can be relieved by special drugs, some of the more serious, you may need surgery to relieve the symptoms, generally you need to go to the hospital for relevant examinations, the doctor gives **method to carry out**.

We must participate in more sports every day to improve the body's resistance, which can prevent colds and respiratory tract and intestinal infections; Once the season changes and the temperature difference is large, try to avoid going out to crowded places as much as possible, and you are likely to be infected with germs and viruses. Once there is a cold and cough accompanied by fever and headache symptoms, it must be carried out in time to avoid aggravation of the condition; You can be vaccinated in time, and vaccinations such as influenza, measles, rubella, etc., can effectively avoid the occurrence of colds and other symptoms; Daily attention should also be paid to cold and warmth, to avoid cold, especially when the season changes, to increase or remove clothes in time.

Finally, we must do a good job of protection in daily life, develop a good eating habit, pay attention to diet, and usually exercise more to improve the body's resistance, so as to better prevent the occurrence of diseases.

There will be fever, headache, diarrhea, slow reaction, upset, irritability, sometimes dizziness, nausea, if it is more severe, there will be epilepsy, convulsions.

There will be chest tightness and shortness of breath, cough symptoms, headache, or high fever, the whole person's mental state is not very good, and there will be fungal infection.

Viral encephalitis can present with headache, dizziness, limb weakness, poor spirit, fatigue, nausea, vomiting. It is recommended to hang the neurology department, check the electroencephalogram, cerebrospinal fluid, and confirm the diagnosis. According to the results, it is reasonable to fight viruses, lower intracranial pressure, and protect brain cells**.

Pay more attention to your diet, focus on easy-to-digest food, maintain regularity, and avoid fatigue. Avoid alcohol.

Meningitis is a serious disease that can lead to death. There are many causes of meningitis, such as viruses, bacteria, fungi, etc., so colds are also easy to cause meningitis, let's understandColds cause symptoms of meningitis.

Symptoms of Meningitis Caused by a Cold Meningitis is a condition in which the delicate meninges or meninges (the membranes between the skull and the brain) become infected. Children from two to three months can develop neonatal meningitis, whether it is a bacterial or viral infection, which can be easily fatal for them. For older children, if it is meningitis caused by a virus, it is not so severe and lasts not so long, about ten days or so.

However, it can be very serious caused by bacteria.

High fever (40), stiff neck, severe headache, loss of appetite, unconsciousness, vomiting, convulsions, lethargy, drowsiness, sensitivity to light, small blood spots on the skin, **rash (from the armpits, hands, and feet), these symptoms of meningitis are similar to those of colds, and are often the cause of misdiagnosis. Changes in symptoms may occur within a day or two, and some become life-threatening within hours.

In infants and newborns, high fever, headache, and stiff neck are not typical symptoms, and sometimes hypothermia occurs. Symptoms in this group include high-pitched and persistent crying, unusual drowsiness, poor appetite, extreme sensitivity, and some distended chimneys.

In older people, these symptoms may or may not occur, but they may or may not show insidious symptoms, such as confusion and obtundation.

Severe bacterial meningitis can also cause shock, coma, or convulsions.

Examination of meningitis in neonatal disease The doctor will confirm the diagnosis of meningitis according to the clinical manifestations and examination, and lumbar puncture should be performed. In order to alleviate the pain caused by this procedure, it is usually performed after anesthesia in the hospital. A small sample of cerebrospinal fluid is taken with a needle pierced between two bones in the spine.

If the cerebrospinal fluid is clear, the fluid becomes cloudy, or the cells are bleeding and suppurating, meningitis should be suspected, and special culture tests are required. Blood samples, urine samples, and ocular and nasal secretions will be collected. Because the disease progresses rapidly, it should be done immediately, even before the results of the tests.

In addition, it is necessary to distinguish the following diseases:

1. Purulent meningitis, the most easily confused is Haemophilus influenzae meningitis.

2. Viral central nervous system infections are mainly viral encephalitis, viral meningoencephalitis and viral myelitis can be confused with the nodule brain, among which sporadic viral encephalitis needs to be identified more than epidemics.

3. The clinical manifestations, chronic course and cerebrospinal fluid changes of Cryptococcus neoformans meningoencephalitis can resemble cerebral nodules, but the course of the disease is longer and can be accompanied by spontaneous remission. Symptoms of chronic progressive intracranial hypertension are prominent and unequal to other manifestations of meningitis. This disease is less common in small germanium, so it is easy to be misdiagnosed as a nodularity.

4. Children with brain abscess often have a history of otitis media or head trauma, sometimes secondary to sepsis. Often with congenital heart disease. Children with brain abscess often have focal brain signs in addition to meningitis and intracranial hypertension.

Fever is also a condition of cold, meningitis is caused by a severe cold fever, if the meningitis is mild, it is okay, if it is serious, it can easily lead to cerebral palsy, so it is unimaginable. Therefore, children with a cold and fever must not be delayed, must be timely, as soon as the child is found to have a fever, immediately give the child a little crack This is a pediatric drug that has a good effect on fever, if everyone is so careful when taking children, there will be no such thing as meningitis in children.
