Narcolepsy is a neurological auto-immune sleep/ wake disorder. A common believe is that people suffering from narcolepsy can just fall asleep. Although it's more complex then that. People with narcolepsy experience frequent excessive daytime sleepiness and fragmented night-time sleep. This often resulting in a chronic state of fatigue.
Another common symptom of narcolepsy is cataplexy, a sudden and transient episode of muscle weakness accompanied by full conscious awareness, typically (though not necessarily) triggered by emotions such as laughing, crying, terror, etc. affecting roughly 70% of people who have narcolepsy.
These symptoms have a great impact on a persons social and professional life (school and career). Often people suffering from narcolepsy lose their job, friends, relationships and experience trouble at school. A better general understanding of narcolepsy and slight changes in the social acceptance could really improve a narcoleptics quality of life.
