Understanding of Consciousness in Absence Seizures: A Literature Review

“… 8 This brings forth the intriguing possibility that impairment in consciousness is not caused by, but rather predisposes to, prolonged spike-wave discharges. 49 The suggested permissive role of the DMN in absence seizure occurrence aligns well with the observation that absences occur more frequently in periods of fatigue or rest, when the DMN is active. 6 Alternatively, abnormal fMRI signals prior to seizure onset could be explained by changes occurring in deeper brain structures, which are not captured by surface EEG electrodes.…”
