Abstrakt		The diagnosis of brain death is primarily based on the clinical diagnosis of deep coma, loss of all brainstem reflexes and the demonstration of apnoe. Neurophysiological tests are recommended by a number of national professional societies as confirmatory tests only to confirm the clinical signs and shorten otherwise necessary waiting periods of 6 to 12 hours. Most brain death codes allow the use of the EEG which must demonstrate electrocortical silence over a certain period. Evoked cerebral potentials can demonstrate the successive loss of activity of various afferent pathways and are accepted in some countries as a confirmatory test. Beside these methods which confirm the loss of bioeelctrical activity of the brain, other neurophysiological tests which demonstrate the loss of cerebral perfusion can be implemented. Brain scintigraphy can confirm the loss of isotope uptake into the brain. Doppler sonography also demonstrates cessation of brain perfusion. Cerebral panangiography may also be used to demonstrate the loss of brain perfusion but is less desirable since it might endanger the patient.
