A major proposed mechanism of SUDEP is the concept of electro-cerebral shutdown, seen on scalp EEG as prolonged post-ictal generalized EEG suppression (PGES). In this case-control study, Dr. Lhatoo reports that prolonged PGES (>50 seconds) appears to identify refractory epilepsy patients who are at risk of SUDEP and risk of SUDEP may be increased in direct proportion to duration of PGES. However, the evidence has been inconsistent in determining the role played by PGES in SUDEP See PGES is associated with generalized seizures by Surges . PGES is seen most often after generalized tonic-clonic seizures, which is a well-known risk factor for SUDEP but it is not a consistent post-ictal finding.
