Active clinical trials for "Consciousness Disorders"

Demonstrating that diagnostics of the state of consciousness and cognitive functions of patients with consciousness disorders performed using C-Eye X (based on eye-tracking technology) allows a more objective assessment of state of patients who were wrongly diagnosed based on popular methods using in a clinical practice (like behavioural scales on paper forms).

This study explores the changes in whole-brain connectivity that occur during recovery from severe Traumatic Brain Injury and how these changes are related to the recovery of consciousness. Multimodal neuroimaging techniques will be used in a longitudinal fashion while patients are undergoing neurorehabilitation and after one-year of the TBI episode.

To validate the French version of the CAM, a multicenter diagnostic study will be conducted. The principle of this study is identical to the study of Inouye which initially validated the CAM in 1990. This is to verify the diagnostic properties of the CAM (French version) compared to the gold standard represented by the confused state of psychiatric diagnosis using the DSM. A representative sample of geriatric patients for whom a delirium is suspected, will be recruited in the various participating centers, patients will undergo two consecutive visits: A visit by a geriatrician, during which the confused state of the patient will be evaluated using the French version of the CAM. A visit by a psychiatrist during which the diagnosis of confusional state will be evaluated using the gold standard criteria of the DSM IV. These two evaluations will be conducted on the same day and blinded from each other. The order of these two procedures will be balanced within each center. This process will allow the calculation of diagnostic parameters of the CAM French version (validation competitive): sensitivity, specificity, positive and negative predictive values .

Altered mental status (AMS) is common in older patients. However there is a lack of standardization in the definition and documentation of this compliant. Different perception of AMS can cause negative impact on interpretation and obtaining scientific data. Although definition of AMS is so complicated, clinical documentation can be detected in these patients with AMS.

TAVI has become a credible alternative to conventional cardiac surgery in aged high-risk patients with aortic valve stenosis. A large part of these procedures are performed with sedation using remifentanil target-controlled infusion plus local anesthesia. However, a significant proportion of the patients experience postoperative delirium, with subsequent worsened outcomes, time-consuming interventions, and increased costs. The use of hypnosis before and during TAVI could decrease the incidence of postoperative delirium thanks to less opioids and hypnotics consumption. Thus, the investigators ought to evaluate the potential advantages of hypnosis vs. remifentanil target controlled-infusion during TAVI procedures.

The primary aim of this research proposal is to use multimodal metrics (e.g., clinical data and advanced neuroimaging) in the early (i.e., acute hospitalization) phase of recovery from COVID-19-related disorders of consciousness to predict outcome at 3, 6, and 12 months post-hospitalization. We aim to construct an algorithm that synthesizes the results of these metrics to help predict recovery.

To compare functional connectivity after severe traumatic brain injury (TBI) between a group of post-comatose TBI with restored consciousness and a group of post-comatose TBI with persistant disorder of consciousness at admission in rehabilitation

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.

The aim of this study is to assess the utility of advanced magnetic resonance imaging (MRI) and electroencephalographic (EEG) technologies for predicting functional outcomes in patients with severe traumatic brain injury (TBI).

Caregivers of patients with disorders of consciousness are highly prone to developing mental health issues. The aim of this study is to investigate the psychological symptoms and care burden of caregivers of patients with disorders of consciousness (DoC), and to examine which characteristics of patients were burden predictors to caregivers.
