Invasive Epilepsy Monitoring: The Switch from Subdural Electrodes to Stereoelectroencephalography

Abstract Stereoelectroencephalography (SEEG) has experienced an explosion in use due to a shifting understanding of epileptic networks and wider application minimally invasive epilepsy surgery techniques. Both subdural electrode (SDE) monitoring SEEG serve important roles defining the epileptogenic zone, limiting functional deficits, formulating most effective surgical plan. Strengths include ability sample difficult reach, deep structures brain without craniotomy disrupting dura. is complementary treatment options may reduce gap patients who are hesitant about resection. Understanding strengths limitations SDE allows epileptologists choose best modality for each patient living with drug-resistant seizures.
