Value of ultralong‐term subcutaneous EEG monitoring for treatment decisions in temporal lobe epilepsy: A case report

Abstract

Abstract Treatment decisions in epilepsy critically depend on information on the course of the disease, its severity and options for specific local interventions. We here report a patient with pharmaco‐resistant non‐lesional temporal lobe epilepsy with evidence for predominant right temporal epileptogenesis. While seizure frequency had been grossly underestimated for many years, ultralong‐term monitoring with a subcutaneous EEG device revealed actual seizure frequency (66 over 11 months vs four patient‐documented seizures), providing objective data on treatment efficacy and additional supportive lateralizing information that played a decisive role for the choice of surgical treatment, which had been rejected by the patient prior to this information.
