Narcolepsy
Narcolepsy is a rare disorder that causes people to suddenly fall asleep with little warning. This is because sufferers’ brains are unable to regulate sleeping and waking patterns in a normal fashion.
There are a number of symptoms of narcolepsy, although not everyone will experience the same ones. In addition, some sufferers experience regular symptoms, whilst others are less frequently affected. Symptoms include:
Excessive daytime sleepiness – This is usually the first sign of narcolepsy but is often just misjudged as people being lazy.
