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.

How to test for meningitis?

The main methods for meningitis examination are lumbar puncture and cerebrospinal fluid testing. Cerebrospinal fluid examination may show increased pressure, turbid appearance, and purulent changes, containing a large number of white blood cells and neutrophils. Routine blood tests may also show a white blood cell count significantly higher than normal, predominantly composed of immature neutrophils. Additionally, it is possible to check electrolytes and use auxiliary diagnostic tools such as X-rays, CT scans, and MRI to confirm the diagnosis, facilitating early detection and treatment.

How to test for meningitis?

Meningitis is a very common disease in neurology, and the most common causes are infections, including viral infections, common bacterial infections, tuberculosis infections, and fungal infections. The main methods of examination for meningitis are as follows: First, physical examination. A physical examination can reveal neck stiffness in the patient, and positive meningeal irritation signs. These examinations are non-invasive and very safe. Second, a lumbar puncture can also be performed. A lumbar puncture can be used to observe whether the fluid pressure is high, and also to collect cerebrospinal fluid to examine its color, perform cytological and biochemical analyses, and culture the cerebrospinal fluid. This is very important to definitively determine the presence of meningitis and to identify the type of infectious agent involved. Additionally, enhanced magnetic resonance imaging can also be performed to see if there is significant enhancement of the meninges.

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.

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.

How is meningitis treated?

The treatment of meningitis is comprehensive. Firstly, medication should be based on the cause of the disease. For example, if it is caused by bacteria, sensitive antibiotics should be chosen for treatment; if caused by tuberculosis bacilli, standard anti-tuberculosis treatment should be applied; if caused by fungi, appropriate antifungal drugs should be used, and so forth. Additionally, symptomatic treatment is necessary, such as timely decompression treatment for increased intracranial pressure; fever reduction, especially for patients with high fever; and controlling seizures in patients with anticonvulsants. Moreover, it is important to maintain nutritional and electrolyte balance and ensure that the respiratory tract remains clear, among other things. If there are complications, they should be actively treated. (Specific medications should be administered under the guidance of a physician.)
