Patients checking for intracranial infections should consult a neurologist for treatment. Clinical intracranial infections mainly include encephalitis and meningitis. Meningitis refers to the symptoms that occur when the pathogen invades the patient’s soft meninges, while encephalitis refers to the pathogen invading the patient’s brain parenchyma, causing the patient to experience symptoms that require active treatment. Both encephalitis and meningitis can lead to symptoms of infection, such as fever, headache, nausea, vomiting, blurred vision, and other manifestations of cranial hypertension, but there may be differences in symptoms depending on the pathogen that is infecting the patient. In case of tuberculous meningitis, the patient will show symptoms of generalized bacteremia, manifesting symptoms of tuberculosis toxicity such as low afternoon fever, night sweats, and generalized weakness. When the patient’s encephalitis worsens, it may cause hemiparesis or monoparesis of the limbs, seizures, and the patient may have impaired consciousness.
