Patients with Parkinson’s disease usually have varying degrees of sleep disorders, and some foreign literature reports that the incidence of PD with sleep disorders is 42%-98%, which is twice as high as that of the normal population. Sleep disorders mostly appear in the late clinical stage of Parkinson’s disease, but can also appear in the early clinical stage, that is, sleep disorders can precede the appearance of motor symptoms, which should attract the attention of clinicians and actively take appropriate treatment measures. 1, insomnia Insomnia is the most common type of sleep disorder in patients with Parkinson’s disease, including difficulty falling asleep, easy waking, and persistent sleep disorder (e.g., laminar sleep), which is a manifestation of early sleep abnormalities. Patients have an increased number of awakenings, waking times greater than 30 minutes, and reduced actual sleep time, less than 6 hours per night. Sleeping difficulties are common in patients with Parkinson’s disease who have psychiatric symptoms such as anxiety and depression. Increased muscle tone, decreased motor ability, severe tremor, and mental retardation can further exacerbate the difficulty in falling asleep. Intermittent sleep is the earliest and longest lasting sleep abnormality in patients with Parkinson’s disease. 2, REM sleep behavior disorder refers to the abnormal behavior that occurs in REM sleep, when the patient seems to experience a terrible dream, a variety of rough behavior, endangering themselves and others, its incidence is about 15% to 47%. Symptoms are characterized by a variety of complex behavioral abnormalities during sleep, mostly violent and rough movements, more often in men than women, and often injuring bed partners or self-injury. The prevalence of RBD is higher in patients with Parkinson’s disease than in healthy people, and those with RBD are also more likely to have non-motor symptoms such as hallucinations, upright hypotension and dementia. 3 , excessive daytime sleep EDS is caused by patients with nocturnal sleep disorders, characterized by wakefulness at night and drowsiness during the day. PD patients with EDS have more cognitive and motor impairments than PD patients without EDS; the incidence of EDS is significantly higher in PD patients with more severe Parkinson’s disease symptoms, long-term dopaminergic medication, and with depression. EDS affects patients’ cognitive and motor functions, and its occurrence is associated with long duration of dopaminergic drug use, high dose, high hallucinations, advanced age and advanced disease. Imaging studies have found that patients with EDS have varying degrees of extensive gray matter atrophy of the cerebral cortex. 4 , sleep attacks, i.e., sudden onset of unrestrained sleep, is a form of EDS, similar to episodic sleeping sickness, manifested as an unprecedented, episodic, irresistible sleep, usually lasting a few seconds. Eleven percent of patients with PD have had at least one traffic accident in the past 5 years, and 1-4% have experienced at least 1 episode of sudden, very dangerous sleep while driving. Recent studies have concluded that both dopamine agonists and dopamine replacement drugs can cause sleep episodes and that the occurrence of such side effects can be reduced by adjusting the drug dose.
