“…Bickford and Butt (1955) described TWs in hepatic encephalopathy [ 8 ], an EEG pattern previously referred to as “ blunted spike-and-wave ” [ 9 ]. The concept of periodicity was then applied to Creutzfeldt–Jakob disease (CJD) [ 10 ], post-anoxic syndrome [ 4 , 11 ], and repetitive focal or lateralized sharp wave discharges [ 12 ].…”

Historically, periodic EEG patterns were described as any pattern with stereotyped paroxysmal complexes occurring at regular intervals, i.e., the period (T). T is the sum of the duration of the waveform (t1) and, eventually, the duration of the interval between two consecutive waves (t2). The American Clinical Neurophysiology Society introduced the concept of a clearly discernible inter-discharge interval between consecutive waveforms (i.e., t2). As this definition was not applied to what have previously been termed triphasic waves and in some cases of lateralized periodic discharges, we propose reconsideration of terminology that includes historical use of definitions. This will allow the development and usage of the concept for periodic EEG patterns as any runs of stereotyped paroxysmal waveforms separated by nearly identical intervals and prolonged repetitive complexes on the EEG. Prolonged expression means EEG is recorded for a sufficient period of time to prove that the pattern is repetitive, thus resulting in a monomorphic/monotonous pattern. More important than the inter-discharge interval (t2), periodic EEG patterns occur at time regular intervals (T). As a result, periodic EEG activity should be considered along a continuum and not the opposite of rhythmic EEG activity where no interval activity exists between consecutive waveforms.

“…2;3 The duration of cardiac arrest is the most important factor determining prognosis; greater than 4-5 min of complete arrest of cerebral circulation may cause irreversible brain damage. 4 However, it is not always easy to accurately measure the duration of cardiac arrest in such patients. Furthermore, as severe neurological deficits occur frequently in patients who survive the acute stage, it is important to have some means of predicting prognosis after resuscitation.…”

“…Supporters of DCD consider surgical removal of organs to constitute "sufficiently small" harm to dying donors, so that they should be allowed to voluntarily accept that harm, thus laying the moral and ethical framework to, ultimately, abandon the deaddonor rule (6). With the growing acceptance of resuscitation of pediatric victims of circulatory arrest for the sole purpose of organ donation (7), it is imperative to wait for at least 10 -15 mins after circulatory arrest (as the President's Commission concluded 25 yrs ago) to confirm the total cessation of the entire brain, including brain stem, activity before re-initiation of resuscitation for organ viability and procurement. Placing it there would create the mistaken impression that a special 'definition' of death needs to be applied to organ transplantation, which is not the case" (page 80) and "The statute recommended [in this report] aids in that process of recognition by providing a legal standard to distinguish the dead from the dying" (page 84) (4).…”
