Acute Effects of Focused Ultrasound Modulation on EEG Behavior in Status Epilepticus Patients
Trial Parameters
Brief Summary
In this study, the investigators propose Pulsed Low-Intensity Focused Ultrasound (PLIFU) stimulation of brain regions that modulate (thalamus) or generate focal motor seizures (primary motor cortex), with the goal of ameliorating seizure activity in subjects in non-convulsive or focal motor status epilepticus. The course of treatment will consist of an initial 10 minute PLIFU treatment session with an option for a 2nd session if necessary. The primary objective of this study is to determine whether PLIFU reduces or suppresses epileptic activity in patients with Non-Convulsive Status Epilepticus (NCSE)/Focal Motor Status Epilepticus (FMSE) that have not responded to standard of care.
