Brief Summary

Disorders of consciousness frequently occur at the acute phase of brain injuries. For the most severe cases, consciousness impairment can be prolonged. To optimize the medical plan and the goal of care, it is fundamental to have precise tools to predict chances of recovery of consciousness and potential disability. Currently, multimodal assessment including behavioral, neurophysiological and neuroimaging technics is recommended. However, the respective predictive values of these markers are poorly understood and decision making is challenging when results are contradictory

Outcome Measures

Primary Outcomes (1)

  • prognosis accuracy of respective predictive markers of consciousness recovery

    Calculation of the value (Chi2 tests, specificity, sensitivity, positive and negative predictive values of each tests and of their combinations to distinguish patients states and outcome (24-month GOS-E ≥ 4 or \< 4).

    24 MONTHS

Secondary Outcomes (1)

  • GOS-E Glasgow outcome scale - Extended

    6, 12 and 18 months

Study Arms (1)

Consciousness disorder patients

The overall outcome of this project will allow to draw better single-patient predictions of state, prognosis, and rehabilitation strategies and furthermore, a better understanding the pathophysiological mechanisms behind DoC that could result in groundbreaking new personalized therapeutic approaches. Based on the collected data, we will evaluate the respective diagnostic accuracy of all the markers acquired in clinical practice regarding the clinical outcome at 2 years.

Other: repeated neurological, behavioral assessments and conventional, quantitative and functional brain imagery

Interventions

Based on the collected data, we will evaluate the respective diagnostic accuracy of all the markers acquired in clinical practice regarding the clinical outcome at 2 years.
