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.

Does meningitis cause fever?

Generally, patients with meningitis exhibit symptoms of fever, along with headaches, nausea, vomiting, or some cognitive impairments and confusion. It is advised that everyone should be cautious and distinguish the symptoms of meningitis from those of common colds, and perhaps visit the department of neurology at a hospital for proper diagnosis and targeted treatment. Under the circumstance of meningitis, it is crucial to follow the doctor's guidance and actively cooperate with the treatment. Typically, a regimen involving anti-infection and antiviral medications is necessary for about two to three weeks, and most patients have a favorable prognosis. Additionally, it is important to maintain a relaxed mood, avoid excessive stress, and drink adequate water to promote excretion.

Differences between Viral Meningitis and Tuberculous Meningitis

Virial meningitis and tuberculous meningitis sometimes require additional differentiation in clinical practice because their treatment plans are significantly different. Virial meningitis has a relatively abrupt onset and is caused by a viral infection, generally having a good prognosis. Patients with tuberculous meningitis usually exhibit symptoms of tuberculosis toxicity such as low fever, night sweats, and fatigue before the onset of the disease. Commonly, other forms of tuberculosis can be identified, such as pulmonary tuberculosis or intestinal tuberculosis. An important diagnostic tool for differentiation is the lumbar puncture. In viral meningitis, the lumbar puncture pressure is generally not particularly high, whereas in tuberculous meningitis, the lumbar puncture pressure is very high, reaching over 400 mm of water column. Additionally, the cerebrospinal fluid (CSF) in tuberculous meningitis is yellowish, and its protein levels are significantly elevated, as are its white blood cell counts, typically ranging from 50 to 500 × 10^6/L. In tuberculous meningitis, the levels of glucose and chloride in the cerebrospinal fluid are significantly decreased, especially chloride, which is a prominent indicator for diagnosing tuberculous meningitis. In contrast, such clear changes are not observed in the lumbar puncture for viral meningitis. Another aspect to consider is the treatment response; if antiviral treatment is ineffective, the possibility of tuberculous meningitis should be considered.

Does meningitis cause headaches?

Meningitis is an inflammation of the meninges caused by pathogenic microorganisms, such as bacteria, tuberculosis bacteria, viruses, fungi, etc., which can all cause meningitis. Common symptoms of meningitis include fever, headache, nausea, vomiting, etc., thus patients with meningitis do experience headaches. Moreover, headache is one of the most common symptoms in patients with meningitis. Often, patients suffering from headaches will experience symptoms of nausea and vomiting, which is frequently projectile, and in many cases, the headache can be alleviated after vomiting.

Meningitis examination methods

The examination methods for meningitis mainly include several types. The first is the lumbar puncture examination, which is a very important diagnostic tool. Through lumbar puncture, one can observe the cerebrospinal fluid (CSF) pressure, its color, and perform laboratory tests on the CSF to examine biochemical properties and cell count changes. Additionally, it is possible to culture pathogens from the cerebrospinal fluid, which is of great auxiliary value in the diagnosis and differential diagnosis of meningitis. Secondly, patients with meningitis also need to undergo physical examinations. If signs of meningeal irritation are found during the physical examination, it also indicates meningitis. Thirdly, patients may need to undergo enhanced Magnetic Resonance Imaging (MRI) of the brain. If the meningitis lesions are severe, meningeal enhancement can be seen.

What are the symptoms of meningitis?

The symptoms of meningitis mainly include headache, nausea, vomiting, fever, epileptic seizures, and mental abnormalities. Severe cases may also present with disturbances in consciousness and signs of meningeal irritation, among others. Therefore, when a patient exhibits the above symptoms, the possibility of meningitis should be considered. The patient needs to promptly visit the neurology department to undergo a cranial CT scan, cranial MRI, electroencephalogram, and lumbar puncture for cerebrospinal fluid analysis to confirm the diagnosis. Treatment should be based on the test results, selecting appropriate anti-infective medications. For example, patients with viral meningitis should be treated with antiviral medications such as acyclovir and ganciclovir; patients with bacterial meningitis should be treated with potent antibacterial drugs, including carbapenems and quinolones; patients with tuberculous meningitis should receive antitubercular drugs, such as isoniazid, rifampin, and ethambutol. In addition, patients may also need symptomatic treatments such as dehydration to reduce intracranial pressure, fever reduction, and control of psychiatric symptoms. (Medication should be used under the guidance of a doctor.)
