Editor-In-Chief: C. Michael Gibson, M.S., M.D. [1]

Overview

Central nervous system infections are those infections of the central nervous system (CNS). There are four main causes of infections of the nervous system: bacterial, viral, fungal and protozoal. Bacterial infections can be pyogenic infections (e.g., meningitis; brain abscess; subdural and epidural abscesses), tuberculosis, neurosyphilis, or leprosy. Viral infections may be meningitis, encephalitis, poliomyelitis, slow virus infections, acquired immune deficiency syndrome (AIDS), and post-infectious syndromes. Fungal infections may be meningitis or meningoencephalitis, brain abscess, or spinal epidural infection. Protozoal infections include toxoplasmosis, malaria or amoebic infection.
