This study investigates the prevalence and combinations of sleep disorders in early-stage Parkinson's disease (PD) patients, comparing them to healthy controls. Sleep disorders, including insomnia, REM sleep behavior disorder (RBD), excessive daytime sleepiness (EDS), restless legs syndrome (RLS), and sleep-disordered breathing (SDB), were systematically diagnosed using medical interviews and video-polysomnography in 162 PD participants and 58 healthy controls from the ICEBERG cohort. The results show that sleep disorders are frequent, with 71% of PD participants experiencing at least one type of sleep disorder, and half of them having multiple sleep disturbances. Insomnia was the most common disorder (41%), followed by definite RBD (25%), EDS (25%), and RLS (16%). These disorders were more prevalent in PD participants compared to controls, except for SDB, which was equally common in both groups. The number of sleep disorders increased with disease duration and dysautonomia. Insomnia was associated with female gender, shorter sleep time, and RLS, while RBD was linked to dysautonomia and advanced age. EDS was associated with psychiatric and motor symptoms, as well as the sedative effects of dopamine agonists. The study highlights the complexity and organic nature of sleep disturbances in early-stage PD, emphasizing the need for comprehensive clinical evaluation and management.This study investigates the prevalence and combinations of sleep disorders in early-stage Parkinson's disease (PD) patients, comparing them to healthy controls.
