Transcranial Doppler is performed daily in Intensive Care Unit in brain damaged patients. For a few years now, the measurement of the photomotor reflex by quantitative Pupillometry has been routinely performed in Intensive Care Units. The objective of this work is to see if Transcranial Doppler recorded parameters and Pupillary parameters are correlated to the neurological prognosis evaluated at 9 months by the Modified Rankin Score (mRS) and the Glasgow Outcome Scale Extended (GOS-E).

| Label | Type | Description | Intervention Names |
|---|---|---|---|
| brain damaged patients | All major brain damaged patients (stroke or head trauma) admitted to reanimation will be included. In the usual practice, they have a Transcranial Doppler and the measurement of the photomotor reflex by quantitative Pupillometry. It is planned to collect the simultaneous values of the different parameters during 2,000 measurements. The data will be collected retrospectively from 01/12/2020, and prospectively from 01/04/2021. |
