Narcolepsy is a sleep disorder that manifests in recurrent attacks of sleep, sudden loss of muscle tone and sleep paralysis.  Having this disorder can greatly impact the learning process.  Attacks of sleep can happen in an untimely manner and the desire to sleep can be resisted only temporarily.  Drug therapy has been useful in regulating the sleep attacks.  The most important thing to remember when advising this population of students is the careful planning of classes and exam times.
