we usually recommend antiepileptic if someone has two seizures within 24 hours. in approximately 70% cases we may not be able to identify any specific cause for seizures for example - infection stroke focal cortical dysplasia (fcd) and tumor as in your case. sinusitis is an incidental finding and at present it seems to be unrelated to epilepsy. you should complete antibiotic course as prescribed for its coverage. for epilepsy he will need antiepileptic drugs (aed). there are many aed to choose from but once you have been given keppra (levetiracetam) you can continue the same as it is a new generation drug with minimal side effects and drug interaction. with the limited information i have i would recommend starting it to prevent future seizures. your neurologist can provide you with its optimal dosing. high white blood cell (wbc) could be related to sinusitis or as a transient rise from seizure itself. it should come down by itself. it would be good to know how long his seizure was and what he did during his seizure. did he passed urine stool or bite his tongue during the episode? revert back with the asked details to a neurologist online --> <link>
