- Multiple sleep latency test (MSLT)—measures the onset of rapid eye movement (REM) sleep, which occurs earlier than normal in narcolepsy
General sleep lab study—often done the night before an MSLT; helps to rule out other causes of daytime sleepiness by monitoring:
- Brain waves
- Eye movements
- Muscle activity
- Heart beat
- Blood oxygen levels
- Total nighttime sleep
- Amount of nighttime REM sleep
- Time of onset of REM sleep
- Degree of daytime sleepiness
- A questionnaire regarding your degree of daytime sleepiness
- Stimulant medicines that increase levels of daytime alertness
- Antidepressants to help treat symptoms of narcolepsy
- Planned short naps throughout the day
- Counseling to cope with issues of self esteem
- Wearing medical alert jewelry
- Exercising on a regular basis
