Vegetative State

Disorders of consciousness (DoC) are severe neurological conditions characterized by impaired awareness and reduced interaction with the environment. Although hyperbaric oxygen therapy (HBOT) may promote neurological recovery, the optimal treatment strategy for individual patients remains unclear. This study aims to develop and validate an artificial intelligence-assisted precision decision support system for HBOT based on dynamic BIS-EEG brain functional feedback. The system will integrate clinical information, neuroimaging data, physiological parameters, consciousness assessments, and HBOT treatment characteristics. Continuous BIS-EEG monitoring will be performed during different phases of HBOT, including compression, oxygen exposure, air breaks, decompression, and post-treatment recovery. Artificial intelligence models will analyze these dynamic brain functional responses to predict treatment effectiveness and support personalized HBOT management. The primary outcome will be improvement in consciousness assessed by the Coma Recovery Scale-Revised (CRS-R). Secondary outcomes include changes in consciousness state, cognitive and functional recovery, and treatment-related adverse events.

The goal of this clinical trial is to learn if a new type of brain stimulation called theta-burst patterned temporal interference stimulation (tTIs) works to improve awareness in people with disorders of consciousness (DoC). The main questions it aims to answer are: 1. Does tTIs help people with disorders of consciousness show more signs of awareness? 2. Does tTIs improve the brain's ability to process information and connect different brain areas? Is tTIs safe and easy for people with disorders of consciousness to tolerate? Researchers will compare a group receiving active tTIs to a group receiving a "sham" stimulation (a look-alike stimulation that delivers no real current) to see if the real stimulation works better. Participants will:Receive either active tTIs or sham stimulation twice a day for 5 consecutive days (total of 10 sessions). Undergo brain activity tests (EEG) and physical exams to check their level of awareness before and after the 5 days of treatment. Have their progress followed by researchers through phone calls at 1, 3, and 6 months after the treatment ends.
