[Role of EEG in the diagnosis of brain death].

Brain death diagnosis is based upon several clinical and paraclinical criteria that have been legally defined. There is a medico-legal protocol when brain death diagnosis is made in order to allow organ removal for a possible transplantation. In France, EEG or cerebral arteriography must legally be used to confirm a clinical brain death suspicion. There is a specific procedure to perform an EEG to confirm the diagnosis of brain death. However all the criteria have been made using conventional paper EEG, while numerized is now used. The comparison of EEG recording using both analogical and numerised acquisition allow us to report several recommendations to use EEG for brain death diagnosis.
