Is a disorder of sleep-wake control in which elements of sleep intrude into wakefulness and elements of wakefulness intrude into sleep. The result is the classic tetrad of chronic daytime sleepiness with varying amounts of cataplexy (emotionally-triggered sudden loss of muscle tone), hypnagogic hallucinations, and sleep paralysis. All patients have sleepiness, but only one-third of patients will have all of these symptoms. 

Hypnagogic hallucinations

All patients with narcolepsy have chronic sleepiness, but they do not sleep more than healthy individuals during a 24-hour period. They are prone to fall asleep throughout the day, often at inappropriate times. The sleepiness may be so severe that patients with narcolepsy can rapidly doze off with little warning; these episodes are commonly referred to as "sleep attacks." Sleepiness associated with narcolepsy usually improves temporarily after a brief nap, and most patients feel rested when they awake in the morning.

Micrographia:
Abnormally small handwriting

People with Parkinson's & Wilson's disease can have abnormally small handwriting. This is because Parkinson is a "hypo-kinetic disorder" which means that it causes difficulty initiating movement.
