Stimulus-induced rhythmic, periodic or ictal discharges (SIRPIDs) are EEG epileptiform periodic discharges (PD) induced by arousal. SIRPIDs lie along an ictal-interictal continuum with debate regarding urgency of treatment. In a patient with SIRPIDs, aphasia and confusion, i.v. lorazepam during EEG resulted in improved level of consciousness, return of verbal interaction and regression of SIRPIDs. This suggests that some forms of SIRPIDs may be associated with an ictal confusional state.
