Hypersomnia is a central nervous system hypersomnolence disorder characterized by excessive daytime sleepiness despite sufficient sleep at night (ie, sleep inertia/sleep drunkenness). Primary hypersomnia, idiopathic hypersomnia, and hypersomnolence disorder refer to a central disorder of hypersomnia. 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. Effective diagnosis is the first step toward managing this disorder; however, because it presents similarly to other sleep disorders, the diagnosis of hypersomnia can be challenging.
