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.)
