Many Parkinson’s patients complain of poor sleep, insomnia, daytime sleepiness, nightmares, etc. These sleep disorder problems affect the health and life of Parkinson’s disease patients, so what are the causes of sleep disorders in Parkinson’s disease patients? One is the difficulty in falling asleep or waking up early due to poor control of Parkinson’s disease symptoms, such as poor control of tremor, which often leads to difficulty in falling asleep; and in sleep, due to muscle stiffness, which leads to difficulty in turning over on one’s own or limb spasms, often causing patients to wake up early. If this is the case, the first consideration is to adjust the medication and increase the dose or number of anti-Parkinson’s disease drugs to control the symptoms of Parkinson’s disease well, thus improving the sleep disorder. Second, drug overdose, some drugs taken too late, may cause cortical excitation, resulting in insomnia in patients, so patients visit the doctor, the sleep problems told experts, experts know drugs, will be based on the patient’s condition to do drug adjustments, patients better not to their own according to the drug instructions, just add or subtract drugs, or even stop drugs. The third is the psychiatric symptoms of Parkinson’s disease patients, such as anxiety, depression, such emotions can affect the quality of sleep. One type of mood is that the patient thinks about his condition and is depressed, and if the treatment is effective, his mood may improve. In the other category, even if the condition improves, the patient’s mood still does not get better. Therefore, the treatment needs to be targeted, to do a good job in the patient’s thinking, communicate more, soothe the patient’s emotions, and establish confidence to overcome the disease. For the latter case, it can be treated with antidepressant drugs appropriately.
