This is the protocol for a review and there is no abstract. The objectives are as follows:
To assess the efficacy and safety of antiepileptic drugs for primary and secondary prevention of seizures in viral encephalitis. We intend to undertake this review with three broad objectives:
do the AEDs reduce the risk of seizures during the acute illness when used as primary prophylaxis routinely for all patients with suspected or proven viral encephalitis;
does the practice of using primary prophylactic AEDs in all patients with suspected/proven viral encephalitis reduce neurological morbidity and mortality;
do the AEDs reduce the risk of further seizures after the occurrence of at least one seizure in patients with suspected or proven viral encephalitis.
