Hypersomnia

Do you ever nodded off in class? Sometimes, we people can not help but fall asleep when we are doing something important such as having our English class. This situation may arise from a lack of  sleep or the usage of drugs or something else. However, if this situation become more serious, it may be identified as disease called Hypersomnia(嗜睡症).

Hypersomnia is a very dangerous disease. People who suffer from Hypersomnia may suddenly fall asleep in time that is not suitable for them to sleep. For example, when they are eating, chatting, or even driving.

Someone may think that patients can prevent from suddenly falling sleep if they have enough sleeping in night. However, the fact is that no matter how long they sleep, they still fall asleep whenever Hypersomnia attack. Morever, now, we people still can not cure this disease.
