1 Usually, scalp-recorded ictal DC shifts are not successfully recorded because movements during clinical seizures could cause artifacts. They are highly specific but low in sensitivity. Ictal DC shifts were seen in 14–40% of recorded seizures and their sensitivity varied.127,131,132 Scalp-recorded DC shifts were detected when seizures were clinically intense, while no slow shifts were observed in small seizures. They were restricted to 1–2 electrodes, very closely related to the onset of low-voltage fast activity and electrodecrement.127,133 Source: Focal Epilepsy, Atlas of Pediatric EEG Citation: Laoprasert P.
