Sleep disorders (including insomnia, heteromorphic sleep and narcolepsy) are present in 70% of Parkinson’s disease patients. More than half of the patients with Parkinson’s disease have sleep disorders years before the onset of the disease, such as nightmares, sleep talking, shouting, swinging fists and kicking feet in the dream, and some patients show difficulty in falling asleep. Classification of sleep disorders in Parkinson’s disease: Nocturnal insomnia: manifested as difficulty in falling asleep, frequent awakening, and early awakening. Some studies have found that Parkinson’s disease with dementia patients are more likely to have sleep-wake cycle disruption, combined with anxiety, depression is an important factor leading to difficulty in falling asleep and early awakening. At the same time, difficulty in turning over or painful twitching caused by movement disorders often lead to frequent awakening at night, resulting in fragmentation of sleep and affecting sleep quality. Daytime sleepiness: About 30% of Parkinson’s disease patients have daytime sleepiness, and the majority of them use levodopa for a long period of time, high dose, more hallucinations, and advanced disease. There are many reasons for daytime sleepiness in patients with Parkinson’s disease, and nighttime insomnia is the main cause of daytime sleepiness. Heteromorphic sleep: manifested as the appearance of various rough behaviors related to dreams during sleep, such as punching, kicking, rolling, jumping, screaming and other violent movements, which can lead to injuries to themselves or people sleeping with them, and the patients often complain of the appearance of nightmares. How to face the sleep problem of Parkinson’s disease patients? First, dinner is mainly carbohydrate, which helps to increase sleepiness. Second, patients who urinate more at night should reduce the amount of water they drink and empty their bladders before going to bed, and a lightweight bedpan should be placed beside the bed to facilitate urination. Third, adjust the psychological state, cultivate good sleep habits, spouses should be more comfort and encourage the patient and maintain a quiet environment. Fourth, adjust the Parkinson’s disease drug dosage and administration time. For some taking time too close to the sleep time will cause insomnia drugs, it is best to change to the morning dose or reduce the dose. Fifth, turn over difficulty, painful convulsions lead to insomnia patients, additional small doses of dopamine before bedtime can improve sleep coherence. Sixth, if necessary, you can use fast-acting, fast-metabolizing sleeping pills, but long-term use of sleeping pills is easy to form a dependence, older or combined with dementia patients should not be used.
