Polysomnography and Multiple Sleep Latency Test data and comparisons between groups.

Data are presented as mean, standard deviation, number and percentage.
*MSLT was performed in 17 out of 18 LRRK2-PD patients since one refused to undergo this test. Percentages on MSLT measures are therefore based on these 17 subjects.
AHI: Apnea-hipopnea index; LRRK2-PD: LRRK2 Parkinson disease; Mentalis: polysomnographic montage quantifying "any" (phasic and tonic) type of EMG activity in the mentalis muscle during REM sleep, using 3-sec mini-epochs (the cut-off for patients with RBD is 18%)[38]; Mentalis plus AT: polysomnographic montage quantifying "any" (phasic and tonic) type of EMG activity in the mentalis muscle plus phasic EMG activity in the right and left anterior tibialis during REM sleep, using 3-sec mini-epochs (the cut-off for patients with RBD is 46.4%) [38]; MSLT: Multiple Sleep Latency Test; NMC: non-manifesting carriers; NMNC: non-manifesting non-carriers; NA: Not applicable; PLMS: Periodic Leg Movements in Sleep; PLMSI: Periodic Leg Movements in Sleep Index; RBD: REM Sleep Behavior Disorder; SINBAR: polysomnographic montage quantifying "any" (phasic or tonic) type of EMG activity in the mentalis muscle and phasic EMG activity in the right and left flexor digitorumsuperficialis muscles during REM sleep, using 3-sec mini-epochs (the cut-off for patients with RBD is 32%)[38]; SOREMPs: Sleep Onset REM Sleep Periods.
