(HealthDay News) -- Narcolepsy is a sleep disorder associated with uncontrollable sleepiness and frequent daytime sleeping.
According to the University of Maryland Medical Center, narcoleptic episodes often occur after meals, but they may also come at dangerous inopportune times, such as while driving.
Symptoms of the condition include extreme drowsiness, difficulty staying awake during classes or work, hallucinations before or after an episode, and sudden loss of muscle function.
There is no known cure, but planned naps, eating light meals, and some prescription medications may help ease symptoms.
