The causes of insomnia in patients with Parkinson's disease are somewhat different from those in the general population. Insomnia in patients with Parkinson's disease is more directly related to the interference of Parkinson's disease symptoms. For example, the insufficient dose of the drug at night makes the patient's body stiff and difficult to turn over; spasms, pains and various physical discomforts of the limbs may lead to insomnia. If the dose of the drug before going to bed is too large, there will be involuntary movements, sometimes accompanied by indescribable general discomfort and restlessness, which will affect the patient's sleep. This requires optimization of Parkinson's drugs to improve sleep by improving nighttime symptoms.
In addition, some Parkinson's disease drugs, such as amantadine, selegiline, etc., have a certain disturbing effect on sleep, and try to avoid using them before going to bed. Amantadine is recommended to be taken before 4pm.
