Study Details

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.

Interventions and Outcome Measures

Arms

experimental: Participants with ongoing non-convulsive or focal motor SE

Adult patients with ongoing non-convulsive or focal motor SE despite treatment with at least 2 ASMs and who are monitored with surface EEG will be screened and enrolled to receive up to 2 sessions of PLIFU.

Interventions

PLIFU

Participants will be treated with up to 2 sessions of PLIFU (on the same day), while monitored with surface EEG and will be observed for the remainder of the hospital stay as deemed by the primary care team. The system non-invasively delivers ultrasound sonications intracranially that selectively target specific areas of the brain.

Primary outcome measure

  • Change in epileptiform activity [ Time Frame: baseline and 10 minutes ]
