#CNS infections and their treatment
SHARE

Central nervous system (CNS) infections are medical conditions caused by various pathogens, such as bacteria, viruses, fungi, or parasites, that affect the brain, spinal cord, or other tissues within the CNS. Below are some common CNS infections, their causes, treatment options, and references for further information.

Contents
Bacterial meningitis [1]:Viral meningitis [2]:Encephalitis [3]:Brain abscess [4]:Fungal meningitis [5]:Tuberculous meningitis [6]:Neurosyphilis [7]:Neurocysticercosis [8]:Progressive multifocal leukoencephalopathy (PML) [9]:References:

Bacterial meningitis [1]:

Cause: Bacteria such as Streptococcus pneumoniae, Neisseria meningitidis, Haemophilus influenzae, or Listeria monocytogenes.
Treatment: Antibiotics (e.g., ceftriaxone, vancomycin, ampicillin), corticosteroids (e.g., dexamethasone), and supportive care.

Viral meningitis [2]:

Cause: Viruses such as enteroviruses, herpes simplex virus, or arboviruses.
Treatment: Supportive care, antiviral medications (e.g., acyclovir for herpes simplex virus meningitis).

Encephalitis [3]:

Cause: Viruses such as herpes simplex virus, varicella-zoster virus, enteroviruses, or arboviruses.
Treatment: Antiviral medications (e.g., acyclovir for herpes simplex encephalitis), corticosteroids, immunoglobulin, and supportive care.

Brain abscess [4]:

Cause: Bacteria, fungi, or parasites.
Treatment: Surgical drainage, antibiotics, antifungal or antiparasitic medications (depending on the causative agent), and supportive care.

Fungal meningitis [5]:

Cause: Fungi such as Cryptococcus neoformans, Candida species, or Aspergillus species.
Treatment: Antifungal medications (e.g., amphotericin B, flucytosine, fluconazole), and supportive care.

Tuberculous meningitis [6]:

Cause: Mycobacterium tuberculosis.
Treatment: Antituberculosis medications (e.g., isoniazid, rifampin, pyrazinamide, ethambutol), corticosteroids, and supportive care.

Neurosyphilis [7]:

Cause: Treponema pallidum (syphilis bacterium)
Treatment: Penicillin, other antibiotics (e.g., ceftriaxone, doxycycline, or azithromycin) in case of penicillin allergy, and supportive care.

Neurocysticercosis [8]:

Cause: Taenia solium (pork tapeworm)
Treatment: Antiparasitic medications (e.g., albendazole), corticosteroids, antiepileptic medications, and supportive care.

Progressive multifocal leukoencephalopathy (PML) [9]:

Cause: JC virus reactivation, typically in immunocompromised individuals
Treatment: Reversing immunosuppression, supportive care, and experimental treatments such as antiviral medications (e.g., cidofovir) or immune-based therapies.
