The most dangerous complication of episodic sleep, also known as episodic sleeping sickness, is that it can easily lead to accidents, such as sudden sudden collapse during normal activities or driving, which can easily lead to trauma or traffic accidents, and drowning during bathing, which can lead to life threatening injuries. Because episodic sleepiness can lead to memory loss, poor concentration, and decreased reaction level, it can have a great impact on normal people’s study, life, and work. Excessive daytime sleepiness can also cause physical weakness, which can be manifested by increased heart rate during activities, clinical symptoms of panic, shortness of breath, and weakness, which can also induce the occurrence of heart disease in the long term. Therefore, once it is determined that it is caused by episodic sleepiness, it is necessary to actively apply methylphenidate, modafinil and other drugs for treatment, and usually try not to travel alone, not to engage in high-altitude work, and not to drive vehicles.
