The treatment of meningitis is comprehensive. Firstly, medication should be based on the cause of the disease. For example, if it is caused by bacteria, sensitive antibiotics should be chosen for treatment; if caused by tuberculosis bacilli, standard anti-tuberculosis treatment should be applied; if caused by fungi, appropriate antifungal drugs should be used, and so forth. Additionally, symptomatic treatment is necessary, such as timely decompression treatment for increased intracranial pressure; fever reduction, especially for patients with high fever; and controlling seizures in patients with anticonvulsants. Moreover, it is important to maintain nutritional and electrolyte balance and ensure that the respiratory tract remains clear, among other things. If there are complications, they should be actively treated. (Specific medications should be administered under the guidance of a physician.)

Is meningitis scary?

Meningitis is a relatively common infectious disease of the central nervous system in clinical practice. The common types of meningitis seen clinically include viral meningitis, tuberculous meningitis, and purulent meningitis. The main clinical symptoms of meningitis include headache, nausea, vomiting, fever, and signs of meningeal irritation; some may present with focal neurological deficits in symptoms and signs. If meningitis is not treated promptly or the treatment is ineffective, it often leads to significant sequelae, and can even endanger the patient's life. Therefore, meningitis is considered a serious disease of the central nervous system. If diagnosed with meningitis, timely treatment is essential, underscoring the seriousness of the disease.

What is meningitis?

Meningitis is predominantly an inflammation that occurs in the meninges and can extend to the brain parenchyma. It is generally caused by pathogenic microorganisms, including common pathogens such as bacteria, fungi, viruses, tuberculosis bacteria, etc. The most common symptoms include fever, headache, nausea, vomiting, stiff neck, etc. More severe cases can present with convulsions, disturbances of consciousness, or even coma. The condition can be mild or severe, and if not treated promptly, it can be fatal in serious cases.

Causes of Meningitis

The main causes of meningitis are bacteria, viruses, fungi, rickettsiae, or other pathogens, which invade the pia mater, spinal cord, and theca mater, causing infection. Clinically, bacterial meningitis is more severe. If it is not treated promptly or if the treatment is ineffective or misdiagnosed, it may lead to death within a few hours or even cause permanent brain damage, resulting in sequelae. Meningitis can affect the dura mater, arachnoid mater, and pia mater. It may also lead to secondary intracranial infections. It is important to choose antibacterial drugs and medications that nourish brain cells and alleviate cerebral edema for symptomatic treatment promptly.

How to rule out meningitis.

Patients with meningitis usually show clinical symptoms such as fever, headache, nausea, and vomiting. To rule out meningitis, the following points should be considered. The first point is to check if the patient has a relevant medical history. If the patient's symptoms are very normal, without fever or headache, the possibility of meningitis is generally not very high. The second point is to pay attention to the physical examination, to see if there is any sign of meningeal irritation. If there is no meningeal irritation, it also does not support the presence of meningitis. The third point involves performing a lumbar puncture to examine the cerebrospinal fluid, checking if the pressure of the cerebrospinal fluid is high, and whether the cellular and biochemical properties within the fluid are normal. If completely normal, the likelihood of meningitis is also very small. Additionally, if necessary, an enhanced MRI scan of the brain should be performed, as meningitis usually shows enhancement.

How to test for meningitis?

Meningitis is a very common disease in neurology, and the most common causes are infections, including viral infections, common bacterial infections, tuberculosis infections, and fungal infections. The main methods of examination for meningitis are as follows: First, physical examination. A physical examination can reveal neck stiffness in the patient, and positive meningeal irritation signs. These examinations are non-invasive and very safe. Second, a lumbar puncture can also be performed. A lumbar puncture can be used to observe whether the fluid pressure is high, and also to collect cerebrospinal fluid to examine its color, perform cytological and biochemical analyses, and culture the cerebrospinal fluid. This is very important to definitively determine the presence of meningitis and to identify the type of infectious agent involved. Additionally, enhanced magnetic resonance imaging can also be performed to see if there is significant enhancement of the meninges.
