The diagnosis of EDS typically involves a thorough medical history, physical examination, and specific diagnostic tests. Some of the commonly used tests include:
- [Polysomnography (PSG)](): An overnight sleep study to monitor various physiological parameters during sleep. - [Multiple Sleep Latency Test (MSLT)](): Measures the speed of falling asleep in a quiet environment during the day. - [Epworth Sleepiness Scale (ESS)](): A questionnaire used to measure the general level of daytime sleepiness.
