Abstract
Recognition of normal EEG variants and artifacts is crucial for accurate EEG interpretation. Normal EEG variants and artifacts often present with distinctive electrographic features that may include morphology, distribution, and occurrence in specific stages (wakefulness, drowsiness, or sleep). In addition, some benign EEG variants and artifacts are better visualized when displayed in a preferred EEG montage. Several of these normal EEG patterns and EEG artifacts may actually mimic pathologic EEG findings, leading to potential misinterpretation of an otherwise normal EEG. Some of these normal patterns may even mimic ictal discharges, leading to potential overtreatment.
