Polysomnographic Findings in Fragile X Syndrome Children with EEG Abnormalities
Table 2
Comparison between fragile X syndrome (FXS) with EEG abnormalities (IEDs) and without EEG anomalies (NIEDs) for polysomnographic macrostructural parameters. This table shows the differences between fragile X syndrome (FXS) children with interictal epileptiform discharges (IEDs) and without them (NIEDs) for polysomnographic macrostructural parameters: interquartile range (IQR); time in bed (TIB-min); sleep partial time (SPT-min); total sleep time (TST-min); sleep onset latency (SOL-min); first REM latency (FRL-min); stage shifting/h (SS-h); awakenings per hour (AWN-h); sleep efficiency percentage (SE%); wake after sleep onset percentage (WASO%); N1, N2, and N3 stage percentages; arousal indexes during the NREM and REM periods; apnea/hypopnea index (AHI); oxygen desaturation index (ODI); oxygen saturation (SpO2); nadir and desaturation percentage levels; and periodic limb movement index (PLMI).
