Excessive Daytime Sleepiness is a sleep disorder in which a person is unable to maintain alertness and lacks energy during the daytime hours even after apparently night time rest. CPAP (continuous positive airway pressure) therapy is the number one standard for treating daytime sleepiness.
Symptoms of EDS include need to nap repeatedly during the day, falling asleep during daytime tasks such as driving, working, eating, or while engaging in conversation. In extreme cases, a person with prolonged EDS can begin to appear intoxicated and become unable to complete normal day to day tasks.
The Multiple Sleep Latency Test, or MSLT, is commonly used to diagnose EDS by measuring one’s sleep latency, the time it takes from the start of a daytime nap period to the first signs of sleep.
