How to manage meningitis ?


Meningitis is an inflammation of the protective membranes (meninges) that surround the brain and spinal cord. It can be caused by infections from viruses, bacteria, fungi, or parasites, as well as by non-infectious factors like certain drugs or autoimmune diseases. Meningitis can be life-threatening if not treated promptly, especially bacterial meningitis.


Types of Meningitis


1. Bacterial Meningitis (most serious)

Cause: Bacteria like Neisseria meningitidis, Streptococcus pneumoniae, or Haemophilus influenzae

 Symptoms: Severe headache, high fever, stiff neck, nausea, confusion, seizures, and sensitivity to light (photophobia)

Treatment: Immediate antibiotics and hospitalization



2. Viral Meningitis (more common, less severe)

Cause: Viruses like enteroviruses, herpes simplex virus, or mumps virus

Symptoms: Similar to bacterial meningitis but usually milder

Treatment: Most cases resolve on their own; supportive care like rest, hydration, and pain relief



3. Fungal Meningitis (rare, but serious)

Cause: Fungal infections like Cryptococcus (more common in people with weakened immune systems)

Symptoms: Similar to bacterial meningitis but slower onset

Treatment: Antifungal medications



4. Parasitic Meningitis (rare)

Cause: Parasites like Naegleria fowleri (often from contaminated water)

Symptoms: Sudden, severe symptoms, often leading to death if not treated quickly

Treatment: Limited treatment options; often fatal



5. Non-Infectious Meningitis

Cause: Cancer, certain drugs, head injury, or autoimmune diseases

Symptoms: Similar to infectious meningitis

Treatment: Depends on the underlying cause (e.g., stopping a drug or treating an autoimmune disorder)





Key Symptoms to Watch For

Sudden severe headache

Stiff neck

High fever

Nausea and vomiting

Sensitivity to light (photophobia)

Seizures

Confusion or difficulty concentrating

Drowsiness or difficulty waking up




Diagnosis


Doctors diagnose meningitis using:

Lumbar puncture (spinal tap): Collects cerebrospinal fluid (CSF) for analysis

Blood tests: Check for infection or bacteria

Imaging (CT/MRI scans): Detect swelling or abscesses




Prevention


Vaccines: Protect against Neisseria meningitidis (meningococcal vaccine), Streptococcus pneumoniae (pneumococcal vaccine), and Haemophilus influenzae (Hib vaccine)

Hygiene: Wash hands regularly, avoid sharing utensils, and practice respiratory hygiene

Avoid Contaminated Water: Protect yourself from parasites like Naegleria fowleri by avoiding warm, fresh water where it thrives
