Narcolepsy

Narcolepsy (excessive/ sudden daytime sleepiness)
Narcolepsy is a neurological disorder that consists of sudden unexpected episodes of
daytime sleepiness which typically last about 15 minutes. A person may have several
episodes any time or place during the day.

This occurs in some individuals despite their getting 7-9 hours of quality nighttime
sleep. Some people with this disorder have been known to fall asleep in the middle of
a conversation, driving, or in a business meeting. Additional symptoms may include
paralysis and hallucinations when sleepy. There is not a cure for narcolepsy but most
people can lead normal lives if the condition is properly diagnosed and treated.
