Some people may experience excessive daytime sleepiness (EDS) without realizing the danger thereof and how much sleep is enough. It’s not normal to have to struggle to stay awake at work, at theatres, at parties, while driving or watching a sport game at the stadium.
- 1 What are the causes of Excessive Sleepiness?
Excessive Daytime Sleepiness results mainly from sleep fragmentation or frequent awakenings from sleep. This fragmentation can happen in many sleep disorders, and most prominent in:
- narcolepsy,
- sleep apnea,
- insomnia,
- restless leg syndrome,
- periodic leg movement syndrome,
- Shift work sleep disorder.
For a patient with sleep apnea, the cause of these awakenings is repeated apnea episodes during sleep. That's why the sleep quality is so poor, and that's why the patient wants to sleep more in the morning and throughout the day. The interaction of mediation in patients with Parkinson Disorder can also cause EDS (excessive daytime sleepiness) EDS always exists in patients with narcolepsy.
