Parkinson’s disease is a common neurodegenerative disease in middle-aged and elderly people. While in the past the main focus has been on the manifestations of motor dysfunction such as bradykinesia and resting tremor, in recent years it has been found that depression and sleep disorders are also among the most common complications of PD leading to its incapacitation, and sleep disorders are particularly pronounced. The main sleep disorders in Parkinson’s patients include: 1, insomnia That is, difficulty falling asleep, which may be related to excessive nocturia, dyskinesia, nightmares, limb pain, mental depression and inappropriate use of anti-Parkinson’s disease drugs, which seriously affect their quality of life. 2, abnormal sleep at night It refers to abnormal mental or behavioral abnormalities that occur in the state of deep sleep, such as shouting and hitting during sleep, or the emergence of restless legs at night syndrome, which refers to the unbearable discomfort in the limbs at rest, especially during night sleep, which can only be relieved by pounding or moving the limbs, and the itchy feeling of ants crawling, etc. 3, excessive daytime sleep caused by the patient’s nighttime sleep disorder, characterized by nighttime wakefulness, daytime sleepiness. The occurrence may be related to the prolonged use of dopaminergic drugs, high dose, hallucinations, advanced age and the severity of the disease. 4. Sleep attacks are sudden, uncontrollable sleep episodes that occur without aura and without consciousness, usually lasting a few seconds. The above sleep disorders associated with Parkinson’s disease may be associated with advanced age, nocturnal movement disorders, medications, or the disease itself. They are mainly improved by adjusting the regular schedule and adding sedative-hypnotic drugs.
