Overview Of The Causes And Complications Of Meningitis
Meningitis is a condition in which the membranes covering the brain and spinal cord become inflamed. It can develop due to viral, bacterial, or fungal causes, and it is sometimes fatal. While vaccines are available to prevent certain types of this condition, patients are encouraged to become familiar with the symptoms associated with various types of meningitis. Patients with this condition may experience a headache, fever, stiff neck, sensitivity to light, nausea, and loss of appetite. These symptoms normally develop rapidly, and emergency hospital treatment is often necessary. To diagnose meningitis, doctors perform a physical examination, blood tests, imaging studies, and a spinal tap (lumbar puncture). Treatment for the condition typically consists of intravenous antibiotics, corticosteroids, and rest. Patients who develop seizures as a result of meningitis will also be treated with anticonvulsants.
Some of the most common types of meningitis and their causes and complications are described below.
Viral Meningitis
Viral meningitis is often a mild form of the condition, and it is frequently caused by enteroviruses, a group of viruses that are especially common over the late summer and early fall in the United States. Mumps, West Nile virus, HIV, and the herpes simplex virus can also lead to viral meningitis. Although viral meningitis cannot be treated with antibiotics, most patients completely recover without treatment within a couple of weeks. If treatment is required, doctors normally begin by recommending bed rest and over-the-counter pain medications to alleviate fever and muscle aches. If necessary, corticosteroids might be prescribed to reduce swelling of the brain, and patients who have had seizures will be given an anticonvulsant. If the patient's viral meningitis is caused by the herpes virus, effective antiviral medication is available for treatment.
