Demography data, seizure details at diagnosis of acute encephalitis syndrome, details of etiology, neuroimaging findings and electroencephalography. A detailed neurological examination will be done in all participants and asked for seizure semiology at admission. Seizure details include seizure type, duration, number of seizures, number of days for which seizures were recurring, status epilepticus, encephalopathy in between seizures. After the initial assessment participants would be randomized into 2 groups: Group 1: Anti-epileptic drug for 4 weeks followed by taper in 10-14days and Group 2: Anti-epileptic drug for 12 weeks followed by tapering over 10-14days. The primary outcome would be be to study the seizure relapse rate (proportion) after stopping anti-epileptic drugs in participants with acute symptomatic seizure given 4weeks and 12 weeks anti-epileptic drug therapy in the two study groups.
