The main causes of meningitis are bacteria, viruses, fungi, rickettsiae, or other pathogens, which invade the pia mater, spinal cord, and theca mater, causing infection. Clinically, bacterial meningitis is more severe. If it is not treated promptly or if the treatment is ineffective or misdiagnosed, it may lead to death within a few hours or even cause permanent brain damage, resulting in sequelae. Meningitis can affect the dura mater, arachnoid mater, and pia mater. It may also lead to secondary intracranial infections. It is important to choose antibacterial drugs and medications that nourish brain cells and alleviate cerebral edema for symptomatic treatment promptly.

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.

Is meningitis serious?

Meningitis is a common infectious disease of the central nervous system. Patients with meningitis often experience symptoms such as fever, headache, nausea, vomiting, and neck stiffness. As the disease progresses, they may also experience seizures, motor disorders, disturbed consciousness, coma, and other conditions, with severe cases posing a risk to life. Many patients can still have sequelae after recovery, such as speech impairments, hemiplegia, and decreased intelligence. Therefore, meningitis is a very serious disease, and patients should actively cooperate with doctors for treatment after becoming ill.

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.

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.
