Moreover, we also found a negative correlation between overnight habituation and arousal index close to significance (r s = −0.43, p = 0.056).

The comparison of PSG sleep parameters between the two groups revealed significant differences: for macrostructure, REM sleep latency was longer in iRBD patients compared to HCs, as well as the time spent to reach the first epoch of NREM sleep stage 1 (N1), with the difference in sleep onset latency (SOL) to NREM sleep stage 2 (N2) being near-significant; for microstructure, the density of REMs and the number of arousals in REM sleep were higher in iRBD patients than in HCs.
