OBSERVATIONAL
Conditions
Summary
The purpose of this study is to determine if the use of emotional sound as subject own name (SON) pronounced by a familiar voice (FV) compared to SON pronounced by a non-familiar voice (NFV) during event related potential (ERP) produced a more reliable neurophysiological P300 responses, and to assess the prognostic value of this P300 responses induced by the SON with a FV.
Eligibility
Inclusion Criteria2
- patients hospitalized in ICU for cardiac arrest, stroke, subarachnoid haemorrhage or head trauma,
- persistent disorder of consciousness (DoC) 12 hours after sedation weaning or patient who has benefited from a prognostic assessment for persistent DoC and who has had in this assessment an evaluation by late PEA with MMN and P300 responses only to neutral sounds ("beep" and patient's first name pronounced by an unfamiliar voice) there is more than 6 months (since April 2022)

Interventions
Use of "expressive" sounds, that is to say the own first name pronounced by the voice of the relative to generate the P300 and a sound with an "approaching" character of the subject to generate the MMN. The investigators will thus be able to compare: * MMN: present/absent for each modality (neutral vs approaching sounds) * Wave P3a: latencies and amplitudes for each modality (own first name voice of the near vs unfamiliar).
Retrospective inclusion Have already had an assessment with event related potentials without "emotional" modalities (VF and similar sounds) as part of their care between April 2022 and December 2022 in intensive care at Cochin hospital.
