[Irreversible cerebral function loss (so-called brain death). Further experiences in diagnostic procedures]

Analyzing international 15 years experiences the authors characterize the present situation of knowledges and practical possibilities concerning brain death diagnostics. It must be differentiated between generally accepted obliging criterions and the remaining space of responcibility of the neurologist, who is acting as a member of a brain death commission. In this frame procedures have to be chosen, which allow to diagnosticate without any doubt and as early as possible. Further developmental possibilities are shown.
