Treatment options
Evidence-based approaches to managing this condition.
First-line treatments
Antimicrobial or antiviral therapy
Active treatment with regular monitoring by a healthcare provider is recommended.
High-dose intravenous acyclovir
IV acyclovir is the first-line antiviral treatment for VZV CNS infections including meningitis and encephalitis. Dosing continues for 10-14 days followed by oral antiviral suppression.
Lumbar puncture for therapeutic CSF drainage
Repeated lumbar punctures may be performed for symptomatic relief in cases of elevated intracranial pressure. CSF analysis also monitors treatment response through cell count normalization.
Additional treatment options
Neurological status and imaging surveillance
Serial neurological examinations and neuroimaging monitor disease progression and treatment response. MRI with contrast helps identify complications such as vasculitis or hemorrhagic changes.
monitoringCorticosteroid therapy for inflammation
Short-course corticosteroids may be added for severe inflammation or vasculitic complications. Steroids reduce cerebral edema and inflammatory response while antiviral therapy addresses viral replication.
medicationNeurocognitive rehabilitation
Post-infection cognitive rehabilitation addresses memory deficits, attention difficulties, and executive function impairments that may persist. Occupational therapy and cognitive exercises support functional recovery.
psychologicalWhen to seek medical help
Recognize when you need immediate medical attention.
See a doctor within 24 hours
Moderate to severe symptoms that may indicate worsening of this condition. Prompt medical evaluation is recommended.
