The EEG demonstrated periodic lateralized epileptiform discharges (PLEDs) maximal at the right frontal-central electrode derivations (black arrows). The tracing reflects the interictal-ictal continuum of right frontal PLEDs with left eye movements (blue arrows) from a focal seizure. Continuous EEG monitoring is helpful in identifying unrecognized seizures when mental status remains impaired after a seizure.
LEV was a good choice in this case due to itsí favorable pharmacokinetics, concurrent conditions and their treatments due to a lack of drug-drug interactions. Structural lesions often predict a high risk for seizure recurrence as well as a poor response to treatment. He received additional LEV and recovered without incident.
