Timing is everything: brain zap study seeks best moment to wake awareness
NCT ID NCT03810079
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study tested whether giving a mild brain stimulation (tDCS) when patients are more alert can improve their level of consciousness. Sixteen adults in a minimally conscious state took part. Researchers used EEG brainwave readings to pick the best time of day for stimulation and measured changes in awareness and brain activity.

Inclusion Criteria: * CNS medication stable for at least a week, * Stable diagnosis of MCS (no diagnosis change based on 2 CRS-R performed within 1 week). * Adult (16 years old - 75 years old) * \> 28 days post injury Exclusion Criteria: * open craniotomies, * VPS under the stimulated area (prefrontal cortex), * pacemaker, * metallic cerebral implant, according to safety criteria for transcranial electric stimulation, * severe medical conditions that might influence clinical diagnosis and EEG activity (e.g., severe hepatic insufficiency or renal failure, or sub-continuous or abundant epileptiform discharges on standard EEG recordings).
