Sometimes, your doctor can diagnose narcolepsy based on your symptoms. These include sleep or weakness attacks that you can't control. If your doctor isn't sure, you may have some tests:
- Polysomnogram tests —You will spend a night in a sleep center. Your body will be hooked up to monitors so you can be watched. These will keep track of your heart rate, eye movements, brain waves, and muscle activity while you sleep. Breathing and changes in oxygen in the blood are also checked. People with narcolepsy go in and out of deep sleep faster.
- Multiple sleep latency test—This may be done the day after your sleep test. You will take 20 minute naps every 2 hours during the day. This will check how fast you fall asleep. It will also track how fast you reach different levels of sleep, mainly REM sleep. You may need to fill out questionnaires. People with narcolepsy fall asleep faster.
