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.

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.

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.

Early symptoms of meningitis

Meningitis is primarily a clinical display caused by various factors leading to inflammatory lesions and inflammatory exudation in the meninges. It can be triggered by viral infections, as well as bacterial, tuberculous, or fungal infections. Different pathogens can lead to different symptoms. The initial symptoms of meningitis mainly include the following aspects: First, patients generally experience significant fever, which can range from mild to high and persistent, closely related to the specific pathogen involved. Second, patients will have obvious headaches, as the meninges are irritated, and pain is certain. Third, it usually leads to symptoms of increased intracranial pressure such as nausea and vomiting. Fourth, patients may also experience discomfort and pain in the neck, and upon examination, positive signs of meningeal irritation can be observed.
