What is Meningitis?

21:55 - 4 May , 2021

Disease

t is the swelling of the meninges, which are the membranes that cover and protect the brain and spinal cord, caused by an infection, initially showing symptoms such as high fever, neck numbness, and headache. If it is not treated in time, especially if it is due to a bacterial infection, it can trigger serious complications and even be life-threatening.

Although there may be non-infectious meningitis, caused by allergic reactions and conditions such as cancer and sarcoidosis, the most frequent cause is viral, bacterial, fungal, and parasitic infections, the first two being the most common. 

Most frequent types of meningitis:

Viral: 
It is a benign form that usually disappears on its own without major complications. The most common viruses that cause it are enterovirus and herpes simplex.
Bacterial: 
It can be caused by a direct infection in the meninges or by ear infections, nasal sinuses, neurosurgery, or skull fractures. There are several bacteria that can cause it, but they are usually:

  • Meningococcus.
  • Pneumococcus.
  • Haemophilus
  • Lysteria.

  • Shock and death.

Diagnosis and treatment Meningitis

Once your doctor analyzes your symptoms and clinical history, he or she will perform a physical examination and order a series of tests to confirm the diagnosis, such as blood cultures to identify bacteria, computed tomography, and MRI to observe the degree of inflammation, and a lumbar puncture to obtain an accurate diagnosis.

The treatments used will depend on the type of meningitis:

Bacterial: broad-spectrum antibiotics are prescribed if the specific bacteria causing the infection is not known, along with corticosteroids to fight inflammation. 

Viral: There are no medications for this type of meningitis, but most of the time it clears up on its own in a few weeks. However, the doctor will recommend rest and keep you hydrated, in addition to prescribing painkillers and anti-inflammatories.
