Hypersomnia is a central nervous system hypersomnolence disorder characterized by excessive daytime sleepiness despite sufficient sleep at night (ie, sleep inertia/sleep drunkenness).

Hypersomnia is often accompanied by long nocturnal or daytime sleep, unrefreshing sleep, trouble awakening, cognitive dysfunction, and autonomic symptoms. It exerts a tremendous burden on patients' quality of life and is associated with significant healthcare costs.
