Filter by:Assessment of consciousness and attention in individuals with severe Acquired Brain Injury (sABI) is crucial for planning rehabilitation, but it is often hindered by coexisting sensory-motor and/or cognitive-behavioural disorders. This project aims at evaluating the value of spontaneous eye blinking features to assess patients' attentional abilities and to distinguish patients with unresponsive wakefulness syndrome (UWS) from those in minimally conscious state (MCS). Patients will undergo an EEG-EOG recording at rest and during an auditory oddball task. Eye blinking features on EOG will be analysed and compared to that of healthy individuals. A machine-learning-based algorithm using blinking features for the diagnosis of patients with sABI will be studied and validated preliminarily. This project will help to stratify patients with sABI using easy-to-detect clinical markers, supporting clinicians' decision-making about patient's management. Additionally, blinking patterns related to residual attentional abilities in patients emerged from disorders of consciousness will be investigated.
The goal of this clinical trial is to test how effective the mindBEAGLE device is in allowing people who are unconscious (due to a brain injury or other condition) to communicate using brain waves to answer Yes/No questions. Participants will wear a cap that will be connected to a computer that measures brain waves, wrist bands that vibrate at different strengths, and ear phones that create different levels of loud tones and will be asked to associate Yes/No answers with the vibrations or tones. They will also be asked to "think about" moving different parts of their body to answer Yes or No. The mindBEAGLE device has already been proven effective for this kind of communication in a previous study, and the study team would like to trial it on a population of unconscious people who enter the UPMC Rehabilitation Institute to see if patients are able to be trained to use the device as part of their everyday inpatient rehabilitation until they are discharged, or until they are able to regain consciousness.
The goal of this clinical trial is to learn about the effect of intraoperative infusion of subanesthetic dose of esketamine on conscious status in patients with prolonged disorders of consciousness under sevoflurane anesthesia. Participants will be patients with prolonged disorders of consciousness undergoing surgery with general anesthesia at Beijing Tiantan Hospital. 0.3mg/kg esketamine or saline will be infused will be infused intravenously at a constant speed within 30 min after tracheal intubation/pneumatectomy fixation. Coma recovery scale-revised, Glasgow coma scale, Full Outline of UnResponsiveness scores, SedLine multi-channel electroencephalogram and perioperative adverse events after surgery will be investigated.
Differential diagnosis between Unresponsive Wakefulness Syndrome (UWS) and Minimally Conscious State (MCS) is complicated due to severe cognitive and/or sensorimotor deficits in these patients. In this study the investigators aimed at exploring the diagnostic and prognostic validity of spontaneous eye blinking parameters (rate, amplitude, duration, variability) in a sample of patients with Disorders of Consciousness (DoC). This is a multi-center prospective observational study conducted in patients with Severe Acquired Brain Injury (sABI) and DoC admitted to 8 European participating centers, with clinical data collection not deviating from routine practice. The study is non-commercial and will have a maximum total duration of 24 months.
The clinical condition of severe cognitive-motor impairment of Disorders of Consciousness (DoC; e.g., Vegetative State - VS, and Minimal Consciousness State - MCS), is characterized by a high risk of developing clinical complications. In this study, the investigators propose a new Clinical Complications Scale (CCS) developed to assess the impact of clinical complications on the long-term evolution of a cohort of patients with DoC. This is a multi-site prospective observational study conducted in patients with Severe Acquired Brain Injury and DoC admitted to six centers of Fondazione Don Gnocchi (Italy), with clinical data collection not deviating from routine practice (except for CCS administration). The study is non-commercial and will have a maximum total duration of 24 months. It is planned to assess inter-rater agreement and concurrent validity with a similar instrument (CoCoS scale).
This pilot study in healthy volunteers aims to determine if biological sex has an impact on recovery from dexmedetomidine-induced unconsciousness, and if transcranial magnetic stimulation combined with electroencephalography (TMS-EEG) can be used to measure brain complexity during dexmedetomidine sedation without arousing study participants.
Background: Despite established evidence supporting the use of tDCS in the adult patient with disorders of consciousness, its use in paediatric patients with brain injury is still limited. Regarding the use of tDCS in paediatric patients with DoC, the scientific evidence still appears to be preliminary about the safety profile and requires further data before investigating efficacy on a broad scale. In fact, although the method has been shown to be safe in other clinical conditions, efficacy and tolerability in children with DoC may vary significantly depending on differences in activation threshold and the presence of underlying pathological electrical activity The implementation of clinical trials investigating the safety and tolerability of tDCS in paediatric patients with DoC now represents an essential first step for a future determination of the efficacy of this method in a population for which therapeutic options are currently extremely limited Objective: The study aim to verify the safety of tDCS treatment and to evaluate the effectiveness of stimulation of the left dorsolateral prefrontal cortex by tDCS in promoting improvement in the level of consciousness in paediatric patients with Disorders of Consciousness. Method: in this mono-center, randomised, double blind cross-over controlled pilot study, real or sham tDCS were applied to the left dorsolateral prefrontal (DLPF) cortex of paediatric patients with disorders of consciousness for two weeks, followed by two weeks of washout, then real or sham tDCS were applied to the left dorsolateral prefrontal (DLPF) cortex for other two weeks, followed by another two weeks of washout.
This study first aims to validate the feasibility of a multimodal 5-day 20-minute tACS protocol in subacute brain-injured patients with a disorder of consciousness during their ICU stay, and conduct a clinical pilot study (validation phase). Upon completion of this validation phase and according to obtained results, a randomized clinical trial will be conducted to compare the effects of the 5-day active 10Hz-tACS protocol with a 5-day sham-tACS protocol on brain dynamics modulation. This study will also compare intervention conditions on recovery of consciousness, cognition and function using short-term and long-term measurements.
A randomized controlled study was conducted to explore the efficacy of early transcranial direct current stimulation (tDCS) and repetitive transcranial magnetic stimulation (rTMS) to promote wakefulness in patients with disorder of consciousness (DOC). In order to improve the prognosis of DOC patients with nontraumatic brain injury, we compared the effects of tDCS and rTMS on clinical behavior and neurophysiological performance, and selected a wake-up technique that could improve the prognosis of DOC patients with nontraumatic brain injury as early as possible, so as to reduce the pain of patients and their loved ones, and to reduce the economic burden of society and families.
This study is aimed at evaluating the potential of transcranial magnetic stimulation in patients with acute severe ischemic stroke with DoC while assessing patients with a hybrid neural network evaluation model. This model may be the basis for initiating individualized closed-loop neuromodulation treatment in patients with DoC.
