Detection of cortical arousals in children using frontal EEG leads in addition to conventional central leads.

Study Objective: This study was designed to assess the efficacy of using Fz as an additional electrode in screening arousals during polysomnography in children.

Methods: Polysomnograms from 24 children were randomly selected from a sleep-study database of children from different diagnostic categories. Of the children whose polysomnograms selected, 5 were normal, 5 had severe obstructive sleep apnea syndrome, 5 had mild obstructive sleep apnea syndrome, 5 had snoring, and 4 had periodic limb movement disorder.
