Meningitis, a disease primarily transmitted through close contact, airborne droplets, and poor dietary habits, is mainly caused by bacterial infections leading to purulent meningitis in clinical settings. Some cases are due to tuberculosis bacillus causing tuberculous meningitis. Additionally, there are viral forms of meningitis, most commonly from enteroviruses or Echo viruses. A minority of patients may also develop cryptococcal meningitis. Treatment should involve the use of appropriate antimicrobial drugs based on clinical symptoms and the infecting pathogen, coupled with measures to decrease intracranial pressure and relieve brain edema, ensuring early detection and treatment to prevent complications.

Differentiation between purulent meningitis and viral meningitis

Purulent meningitis and viral meningitis are different diseases. Purulent meningitis is caused by bacterial infection of the meninges. Viral meningitis is caused by viral invasion of the meninges. Generally, purulent meningitis is more severe, and patients may exhibit symptoms of systemic toxin poisoning, such as high fever, nausea, vomiting, sickly appearance, and general weakness. The symptoms of viral meningitis are relatively mild, and the fever is not particularly severe. Another important differentiation is based on the analysis of cerebrospinal fluid. In viral meningitis, the lumbar puncture shows that the white blood cell count is below 1000*10^6/L, and the levels of sugar and chloride are generally normal or slightly low, with protein usually mildly elevated. In purulent meningitis, the cerebrospinal fluid shows a significant increase in white blood cell count, even reaching from 1000*10^6/L to 10000*10^6/L; the protein content is significantly increased, the sugar content is markedly decreased, and chloride levels are reduced. Additionally, bacteria can be found in the cerebrospinal fluid and blood cultures in purulent meningitis, whereas viral meningitis cerebrospinal fluid cultures do not show bacteria.

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.

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.)

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.
