In an electroencephalography (EEG) recording, artifact is present in any tracing or changes in the tracing when it is attributed to a noncerebral source. Artifact can obscure a recording rendering the electrocerebral activity unreadable. The pediatric EEG is subject to the same technical artifacts as seen in adults. Common examples include alternating current artifact (60 Hz) and vertical eye blink artifact during wakefulness. Common examples of pediatric EEG artifacts are rhythmic patting and rocking artifact in the neonate and infant, which may be misinterpreted as an electrographic seizure without clinical signs. Video correlation of the EEG tracing may be indispensable to identify the potential source of artifact. This chapter includes common artifacts that are encountered in the EEG for a pediatric population. Identifying artifact mimicking ictal EEG patterns requires distinction ranging from benign epileptiform variants and induced cerebral activity such as the texting rhythm from common patterns associated with artifact.
