Beyond mortality, the plague of bacterial meningitis on the body and central nervous system has been well described. Included in post-meningitis neurologic sequelae are sensorineural hearing loss, seizures, and focal neurologic deficits.

Furthermore, appropriate timing and dosing of dexamethasone therapy in these patients is crucial and can be easily overlooked.
