What is excessive daytime sleepiness (EDS) due to narcolepsy?
EDS is a medical condition that can leave you feeling sleepy all the time, and you may have a need to sleep during the day. This can lead to problems with work, school, activities, hobbies, and even your relationships.

Narcolepsy can affect your brain's ability to stay awake. Your brain's sleep and wake systems are similar to an on-and-off switch. When the wake system is turned on, the sleep system is turned off, and vice versa. In narcolepsy, the on/off switch is broken, causing sleep to intrude into wakefulness
EDS from narcolepsy can be unpredictable. You can suddenly fall asleep multiple times per day, and it can last from a few minutes to several hours. It’s common to feel this urge to sleep in quiet, relaxing situations, but it can also happen while performing mentally or physically demanding activities
Common signs and symptoms of EDS due to narcolepsy include:

Sleep attacks
Irresistible urge to sleep

Frequent sleepiness
Trouble staying awake and alert during the day
Unrefreshing sleep
Feeling tired regardless of how long you've slept

Brain fog
Difficulty keeping attention and focus during the day


Here’s how EDS due to narcolepsy is diagnosed

Your healthcare provider will conduct a sleep study to confirm a diagnosis of narcolepsy

To diagnose EDS, your discussion with your healthcare provider may include answering a quiz called the Epworth Sleepiness Scale (ESS). In this quiz, you’ll answer questions about your likelihood of falling asleep in everyday situations
