Early detection of antiseizure medication inefficacy using an implantable continuous EEG system and a personalized model: a case study

Abstract

Evaluating anti-seizure medication (ASM) efficacy can be limited by inaccurate seizure diaries and periodic fluctuations in seizure frequency, known as seizure cycles. These limitations may prolong monitoring of ineffective treatments. This study explores implantable continuous EEG monitoring (iCEM™) with Epiminder's Minder® system and timeseries modelling to improve efficacy assessments. This retrospective case study examines a 49-year-old female with drug-resistant focal epilepsy with iCEM (Nov. 2019). The participant maintained a seizure diary and was followed-up for 3 years. ASMs were changed in Aug.-Oct. 2020. A personalised autoregressive model incorporating interictal epileptiform dis..
