Trial Outcomes & Findings for SURESTEP: Transcranial Direct Current Stimulation in Super Refractory Status Epilepticus (NCT NCT03819543)

NCT ID: NCT03819543

Last Updated: 2023-02-16

Results Overview

PRIMARY outcome

Timeframe: Up to 3 hours per EEG recording

Population: Automated and human counting methods found differing numbers of spikes between patients.

EEG epileptiform activity as defined in units of spikes per second for a given patient. Pre-stim compares spike rates during stimulation to before stimulation. Pre-post compares spike rates after stimulation to before stimulation.
