Meningitis is inflammation of the meninges – the fluid and membranes surrounding the brain and spinal cord. There are different types of meningitis such as viral, bacterial, chemical and fungal. Viral meningitis is the most common type followed by bacterial meningitis. Treatment for meningitis depends on the symptoms and severity of infection. Timely treatment can help prevent serious complications. For correct clinical documentation of the condition, physicians can consider utilizing medical billing services.

According to reports from the Confederation of Meningitis Organizations (CoMO), meningitis causes about 2, 30,000 deaths every year and leaves 5,00,000 people with lifelong disability every year. Even though the condition can affect anyone but infants, young children, adolescents and older people are at the highest risk.

Symptoms and Diagnosis

Meningitis is caused when a bacterium, fungus, parasite or virus enters the body via the bloodstream, nerve endings, or even a dormant reactivation in the nervous system and reaches the brain or spinal cord. Mild types of meningitis usually improve without treatment within a few weeks. As the condition can progress quickly, correctly diagnosing and treating at an early stage it is crucial.

In the early stages, inflammation from meningitis may cause symptoms that mimic those of influenza. As the condition progresses and reaches an advanced stage, it can cause . headache, fever, a stiff neck, confusion or difficulty concentrating, seizures, nausea and vomiting, sensitivity to light, sleepiness and skin rashes. These symptoms can appear either suddenly or over a few days (normally about 3 to 7 days). A compromised immune system, age and skipping vaccination are risk factors for meningitis.

If left undiagnosed or untreated in the early stages, meningitis can cause serious, life-long threatening complications and even death. Diagnosis begins with a medical history review. Healthcare providers perform different tests to evaluate for signs of infection around the head, ears, throat and skin along the spine. Common diagnostic tests include – blood culture, and imaging tests such as computerized tomography (CT), magnetic resonance imaging (MRI) and X-rays of the chest or sinuses to identify the signs of infection. Treatment for meningitis will depend on the type of infection and whether it is acute or chronic. Common treatment modalities include antibiotics, corticosteroids, anticonvulsants, oxygen therapy, and sedatives.
