NCT06931665
This study aims to explore the impact of Animal Assisted Therapy (AAT) on brain signal complexity in patients with minimally conscious state (MCS) by analyzing electroencephalogram (EEG) entropy. MCS patients typically exhibit reduced brain entropy compared to healthy individuals, indicating lower brain complexity. The study will assess whether AAT can enhance this complexity, which is crucial for understanding consciousness levels. Entropy, a measure of randomness in brain activity, will be used to evaluate AAT's effectiveness. In addition, electrocardiography (ECG), electrodermal activity (EDA) and behavioral measurements will also be collected.
NCT03810079
This research will test a closed-loop system using EEG-arousal measures (spectral entropy) to define the best moment of the day for application of transcranial direct current stimulation (tDCS) in patients in MCS This study aims at answering the following questions: 1. Is tDCS applied during high vigilance states more effective in increasing the level of conscious awareness than low vigilance states in patients in minimally conscious state (MCS)? 2. Is the EEG pattern (connectivity, complexity) different after application of active or sham tDCS at high vigilance or low vigilance states? 3. Is there a difference in the profile of tDCS-responders as compared to non-responders with regards to etiology, clinical diagnosis (MCS+/MCS-), age, gender, time post-injury, functional outcome, structural and functional neuroimaging findings and EEG markers?
NCT05558930
Previous studies showed the excitatory effect of cerebellar transcranial magnetic stimulation(TMS) on motor cortex.Investigator evaluate the effects of bilateral cerebellar TMS on Coma Recovery Scale-Revised (CRS-R) scores in patients with disorders of consciousness(DOC) in a randomized, double-blinded, sham-controlled, crossover experimental design.
NCT04164680
Recently introduced hybrid PET/MR scanners provide the opportunity to measure simultaneously, and in direct spatial correspondence, both metabolic demand and functional activity of the brain, hence capturing complementary information on the brain's physiological state. Here we exploited PET/MR simultaneous imaging to explore the relationship between the metabolic information provided by resting-state fluorodeoxyglucose-PET (FDG-PET) and fMRI (rs-fMRI) in patients with disorders of consciousness.
NCT04330547
The purpose of this study is to characterize and improve pain and nociception management in patients with disorders of consciousness (DOC). This project is divided into two phases, a first phase to evaluate pain level and a second phase which consist of a clinical trial to evalute pain medication efficacy. The main aim is to evaluate the use of the Nociception Coma Scale-Revised (NCS-R) and its cut-off score (i.e., 5) as an assessment and management tool to define guidelines for managing pain in patients with DOC. In this double-blind, placebo-controlled clinical study, we will evaluate the use of analgesic treatments in reducing pain in subacute/chronic patients. The project will also allow us to validate the NCS-R cut-off score defined previously.
NCT04137497
The aim of this study was to investigate the relationship between behaviorally assessed consciousness levels and responsiveness to nociception in patients with disorders of consciousness (DOC)
NCT04010838
Disorders of consciousness(DOC) is the most serious complications and has been widely paid attention to by the government. DOC patients cause large social and economic burden to our society for there has no effective cure so far. Spinal cord stimulation(SCS) for wake-promoting therapy has aroused scholars' attention and become a hot area recently. There was much debate about the effectiveness of SCS therapy, but because of the limitation of our understanding of consciousness and the uncertainty of parameters of the stimulation, So, to figure out the indications and effectiveness of neuromodulation therapy should be the first step, and finding individual treatment and parameter may have important implications for DOC patients.
NCT02878837
This randomized, open clinical trial sought to compare the use of Midazolam and Dexmedetomidine during surgery in patients under regional anesthesia. The primary objective was to determine the superiority of either drug during the intraoperative period regarding: 1- Depth of sedation and 2- incidence of complications. Secondary objectives included the determination of superiority regarding the postoperative period. For that, patients were randomized into two groups and sedated with either Midazolam or Dexmedetomidine.
NCT02702362
In this study researchers will apply transcranial direct current stimulation (tDCS) for 5 consecutive days in chronic patients in minimally conscious state (MCS).
NCT02566720
This is a pilot study. The objective is to further understand the mechanism by which amantadine improves function in patients with persistent vegetative state and minimally conscious state. Specifically, the investigators will measure the size of the nerve fibers that mediate arousal (reticular activating system, or RAS) pre and post treatment on MRI tractography. MRI findings will be correlated with the Disability Rating Scale (DRS) score. The information gathered from this study will be used to formulate a larger clinical trial.
