Overall, we have found the same sleep disorders in LRRK2-PD than those previously described in IPD (sleep onset insomnia, fragmented sleep, early awakenings, EDS, sleep attacks and RBD) but with a distinct pattern; sleep onset insomnia was more frequent, EDS was similar and RBDwas less frequent and less severe in LRRK2-PD than in IPD. The gene discussed is LRRK2; the disease is sleep disorder.
