What is meningitis, what causes it, and can it be cured?

Meningitis is diffuse inflammatory changes in the leptomeninges. It is caused by various biological causes such as bacteria, viruses, fungi, spirochetes, protozoa, rickettsia, tumors and leukemia to invade the leptomeninges and meninge membranes.

Hello, meningitis is divided into many types and is an infectious disease of the central nervous system, caused by the entry of pathogenic microorganisms into the central nervous system.

Suggestions: Suggestions need to be timely**. If left unchecked, it can lead to death within hours or permanent brain damage. Don't be careless, pay attention to it.

There are many types of meningitis, the more common ones are caused by infection, and some are aseptic meningitis. There are four main types of infectious meningitis: bacterial meningitis, viral meningitis, fungal meningitis, and tuberculous meningitis.

The main manifestations of meningitis are fever, headache, vomiting, and more severe cases can cause impaired consciousness. Examination may reveal a stiff neck, known as nuchal rigidity, which is an important sign. If the diagnosis is confirmed, a detailed examination at the hospital is required, which can be further differentiated by magnetic resonance.

Meningitis is generally divided into four types: bacterial meningitis, tuberculous meningitis, viral meningitis, and cryptococcal meningitis

1. Causes of bacterial meningitis. Bacterial meningitis is caused by a bacterial infection. This kind of bacteria is carried in the nose of healthy people or in the human body, usually it will not cause harm to the human body, but people are prone to infection with this kind of germ when they suffer from a cold, because the nose is inflamed and it is very likely to let this bacteria enter the skull, and it is easy to cause bacterial meningitis if it is not found and treated in time.

In addition, bacterial meningitis can be transmitted by coughing or sneezing.

2. Causes of tuberculous meningitis. Tuberculous meningitis is a non-purulent inflammation of the meninges caused by Mycobacterium tuberculosis, which accounts for about 6% of systemic tuberculosis. Mycobacterium tuberculosis infection is spread through the bloodstream and planted under the leptomeninges to form tuberculous nodules, and after the nodules rupture, a large number of tuberculosis bacteria enter the lower cavity of the arachnoid membrane.

In recent years, the morbidity and mortality of tuberculous meningitis have also increased.

3. Causes of viral meningitis. Viral meningitis can be caused by several viruses, including several viruses associated with diarrhea, one of which is likely to be contracted after being bitten by a large vole, etc.

4. Causes of cryptococcal meningitis. Cryptococcal meningitis can be caused by fungi, and cryptococcus is the most common and can be found in pigeons. Healthy people are less susceptible to fungal-related meningitis, but people with HIV infection, a virus that can cause immunodeficiency in people with AIDS.

As a result, people with AIDS are more likely to develop cryptococcal meningitis.

There are several causes of meningitis. Meningitis can be caused by viral infections, tuberculosis infections, bacterial infections, fungal infections, mycoplasma infections, and chlamydial infections.

Viral infections, tuberculosis infections, bacterial infections, fungal infections.

Hello, Lotus Japonica Rice Porridge: To maintain a healthy immune system and prevent reinfection with meningitis, you should eat a nutritious diet that is low in fat and high in fiber, try to avoid sugar and processed foods, and vitamins are also very useful. For meningitis, there is this lotus japonica rice porridge, which is helpful for meningitis.

Meningitis as the name suggests is meningeal inflammation, the human brain actually has three layers of membranes, the innermost layer is called the leptomeninges, the middle layer is called the arachnoid membrane, and the outermost layer is called the dura mater, meningitis refers to the inflammation of the arachnoid membrane and the subarachnoid space caused by bacterial or viral infection, generally speaking, the more harmful is the inflammation caused by purulent bacteria.

There are many reasons for it, the first is the inflammation of some organs around the brain, including otitis media of the ear, sinusitis of the nose, some infections of the pharynx, and mastoiditis of the masttoid, inflammation destroys the skull, so that bacteria invade the skull and cause meningitis, the second is hematogenous spread, which refers to the bacterial infection in the distant organs outside the brain, and the bacteria enter the brain through the bloodstream infection, the third is the infection caused by the entry of exogenous bacteria caused by trauma to the brain, and a small part of the causes are related to surgery. A very small number of infections may occur after neurosurgery, called iatrogenic infections, and meningitis is mainly caused by these four causes.

Meningitis is caused by various pathogenic bacteria that infect the meninges. For example, viral meningitis is a viral infection that invades the meninges and causes corresponding clinical symptoms, and various pathogenic viruses can infect the meninges. Bacterial meningitis, or purulent meningitis, is a bacterial infection of the central nervous system, invading the meninges.

Fungal meningitis is a fungal infection of the meninges, the common being cryptococcal meningitis neoformans, and the condition is relatively critical. There is also tuberculous meningitis, which is infection of the meninges by Mycobacterium tuberculosis. In conclusion, meningitis is caused by infection with various pathogenic microorganisms.

Hello! The ** that causes meningitis is as follows:

Bacterial meningitis.

It is caused by some kind of bacterial infection. There are 3 types, namely Haemophilus influenzae type B, Neisseria meningitidis and Streptococcus pneumoniae. About 80% are bacterial meningitis.

Usually a small percentage of healthy people carry these germs in their noses or on their bodies and do not injure the human body, but they are transmitted by coughing or sneezing. People are most susceptible to germs when they have a cold because inflammation of the nose makes it extremely easy for bacteria to enter the skull.

2.Tuberculous meningitis.

It is a non-purulent inflammation of the meninges caused by Mycobacterium tuberculosis, accounting for about 6% of systemic tuberculosis. Mycobacterium tuberculosis infection spreads through the bloodstream and implants under the leptomeninges to form tuberculous nodules, and a large number of tuberculosis bacteria enter the subarachnoid space after the nodules rupture. In recent years, the morbidity and mortality of tuberculous meningitis have been increasing.

Early diagnosis and ** can improve efficacy and reduce mortality.

3.Viral meningitis.

It can be caused by several viruses, including several viruses associated with diarrhea, one of which may be contracted after being bitten by a large vole, etc.

4.Cryptococcal meningitis.

Meningitis can also be caused by fungi. One of the most common is Cryptococcus, which can be found in pigeons. Healthy people are less susceptible to fungal-related meningitis, but it is not the same for those infected with HIV, a human immunodeficiency virus that can cause AIDS.

It's usually a fright, or that trauma, take medicine! It will cause meningitis, and the fever ** will also be prone to meningitis if it is not timely.

Meningitis is usually caused by bacteria and viruses and can be transmitted from mother to child, sneezing, food, and close contact, so meningitis is contagious.

During the meningitis epidemic, it is recommended not to participate in large and crowded events. You should wear a mask when you go out and do a good job of protection. At the same time, we should actively exercise in life to improve the body's resistance, which can also effectively prevent the occurrence of meningitis.

Analysis: Hello, combined with your information, the two are not the same, encephalitis, mostly viral (there are many types of viruses) infection, so that the brain parenchymal tissue is damaged after the lesions; Meningitis, usually inflammation of the meninges caused by bacterial (can be a variety of purulent bacteria) infections. However, some children with viral encephalitis also have pathological changes in the meninges.

Suggestion: Although encephalitis and meningitis are both central nervous system infections, the clinical symptoms have some similarities (e.g., fever, headache, vomiting, loss of appetite, stiffness of the neck, listlessness, lethargy or coma, convulsions, etc.). However, encephalitis with damage to the parenchymal tissue of the brain is more likely to cause localized symptoms, that is, paralysis or paralysis in a certain part of the body, and there are more sequelae left after the disease; In children with meningitis, meningeal symptoms are predominant, such as fullness of the anterior fontanelle, severe headache, projectile vomiting, stiffness of the neck, and other manifestations of increased intracranial pressure.

When encephalitis is accompanied by meningitis, meningeal symptoms can also occur.

Meningitis is a common infectious disease of the nervous system that can seriously threaten the healthy growth of children. Meningitis is generally caused by various infections, such as bacteria, fungi, parasites, viruses, etc., which can cause meningitis. After the diagnosis of meningitis is confirmed, it should be carried out against the causative microorganisms**, because the occurrence of meningitis will seriously affect the function of the central nervous system of the person, so it should be carried out in time**.

Meningitis. There are many kinds of ** caused, such as the simple common cold, if you don't look at it, it will also cause this.

Acute meningitis sprays a large number of bacterial droplets, polluting the air, once inhaled by healthy people, in the case of decreased immunity and resistance, meningococcal bacteria will enter the bloodstream from the respiratory tract, and then reach the intracranium, causing meningitis.

The cause of meningitis is that there are symptoms caused by viral infections, fungal infections, bacterial infections and other reasons.

There are many causes of meningitis, it can be caused by a fungal infection, you can take some antifungal infection drugs**, or it can be caused by a cold or trauma. Meningitis is a serious infection of the central nervous system. Brain.
