1, insomnia: manifested as difficulty in falling asleep, frequent awakening, early awakening. Some studies have found that patients with Parkinson’s disease with dementia are more prone to disruption of the sleep-wake cycle, resulting in sleep disorders and worsening of symptoms leading to insomnia. Combined anxiety and depression are important factors that lead to difficulty falling asleep and early awakening. Patients with advanced Parkinson’s disease mostly combine with impaired autonomic function, resulting in increased nocturnal urination can also affect sleep, while Parkinson’s disease movement disorders cause difficulty turning over or painful twitching often lead to frequent awakenings at night, resulting in sleep fragmentation and affecting sleep quality. 2. Daytime sleepiness: About 30% of Parkinson’s disease patients have daytime sleepiness, and most of them use levodopa for a long time, have high doses, have more hallucinations, and are in advanced stages of the disease. There are many causes of daytime sleepiness in Parkinson’s patients, and insomnia at night is the main cause of daytime sleepiness. 3, sleep episodes: refers to the sudden onset of irresistible sleep phenomenon, often lasting from a few seconds to tens of seconds. Some studies have found that dopamine agonists and high doses of levodopa can lead to sleep attacks. Sleep attacks are also associated with age, movement disorders, nocturnal sleep disorders, and associated diseases. 4, allergic sleep: often manifested as a variety of dream-related rough behavior during sleep, such as punching, kicking, rolling, jumping, screaming and other violent movements, can lead to their own or co-sleeper injury, patients often complain of nightmares. Treatment should pay attention to five points 1, adjust the psychological state, develop good sleep habits, spouses should be more comfort and encourage patients and maintain a quiet environment. 2, patients with more nocturnal urination reduce the amount of water drunk and empty the bladder before bedtime, and place a lightweight potty by the bed to facilitate urination. 3. Adjust the dosage and administration time of Parkinson’s disease medications. For some drugs that cause insomnia when taken too close to sleep time, it is best to switch to morning dosing or reduce the dose. Patients who have difficulty turning over and painful convulsions that cause insomnia, additional small doses of dopamine before bedtime can improve sleep coherence. Daytime sleepiness or sleep episodes require attention to adjust the dose of dopamine agonists. 4, for the late emergence of drug efficacy and allodynia of Parkinson’s disease patients with deep brain electrical stimulation (DBS) treatment can significantly improve sleep symptoms, you can often hear the first day after surgery patients lamented, how many years finally comfortable to sleep. 5, if necessary, you can use fast-acting, fast-metabolizing type of sleeping pills, but long-term use of sleeping pills can easily form dependence, older or combined with dementia patients should not be used.
