Polysomnography in Children: Scoring Rules
This chapter discusses changes in Electroencephalogram (EEG) seen during sleep among children. It describes correlate EEG changes with the age among children. The chapter also discuss the rules for respiratory scoring among children. Children are different from adults in terms of neuronal development. Myelination of brain completes by adolescence, hence, their polysomno- graphic recording is not similar to that of adults. Sleep spindles may be seen at the age of 4-6 weeks post-term and are usually seen in post-term 2-3 months old infants, but are often asynchronous over hemispheres. Among children, sleep stages are divided as adults, that is, awake, N1, N2, N3 and Rapid eye movements (REM) in addition to stage. N is scored when all epochs of Non-rapid-eye-movement sleep (NREM) sleep do not contain characteristic waveforms, that is, K-com- plex, spindle, or slow waves.
