Sleep disorders (SDs) are one of the most frequent non-motor symptoms of Parkinson's disease (PD), usually increasing in frequency over the course of the disease and disability progression. SDs include nocturnal and diurnal manifestations such as insomnia, REM sleep behavior disorder, and excessive daytime sleepiness. The causes of SDs in PD are numerous, including the neurodegeneration process itself, which can disrupt the networks regulating the sleep-wake cycle and deplete a large number of cerebral amines possibly playing a role in the initiation and maintenance of sleep.

Sleep disorders (SDs) constitute the second most frequent complaint, affecting 64% of PD patients, ranging from 41.1% in naïve patients to 78.3% in complicated patients. SDs in PD are multifactorial and include nocturnal and diurnal manifestations. Reduced sleep efficiency and an increased number of awakenings characterize sleep in PD. These disturbances are linked, on one side, to PD motor (akinesia, rigidity, and dystonia) and autonomic symptoms (nocturia) and, on the other side, to the presence of concomitant SDs such as REM sleep behavior disorder (RBD), restless legs syndrome (RLS), or breathing disorders such as obstructive sleep apnea (OSA). Diurnal manifestations include excessive daytime sleepiness (EDS) and sudden sleep attacks, which could be a consequence of nocturnal sleep impairment or dopaminergic treatment or, more interestingly, to the neurodegenerative process of PD itself dysregulating the circadian sleep-wake rhythm.
