Disorders of Excessive Somnolence, also known as hypersomnias, refer to a group of sleep disorders characterized by excessive daytime sleepiness or excessive periods of sleep. This condition is associated with an irresistible urge to sleep or difficulty staying awake during the day, thereby causing significant impairments in daily functioning and overall quality of life.
People with disorders of excessive somnolence often experience frequent and long-lasting episodes of sleep during inappropriate times, such as in the middle of conversations, at work, or while driving. Despite obtaining sufficient nighttime sleep, they struggle to stay awake and alert throughout the day, which can lead to problems concentrating, memory lapses, and difficulties performing tasks. This excessive sleepiness can persist for months or even years, with significant impact on social, occupational, and educational activities.
Some common types of disorders of excessive somnolence include narcolepsy, idiopathic hypersomnia, and Kleine-Levin syndrome. Narcolepsy is a chronic neurological disorder characterized by sudden, uncontrollable bouts of sleep during the daytime, as well as symptoms such as cataplexy (sudden loss of muscle tone triggered by strong emotions). Idiopathic hypersomnia refers to excessive daytime sleepiness without cataplexy, often causing prolonged sleep periods without feeling refreshed upon awakening. Kleine-Levin syndrome is a rare sleep disorder characterized by recurrent episodes of excessive sleepiness, binge eating, and behavioral changes.

Treatment approaches could include lifestyle modifications, medication management, and psychological therapies aimed at managing sleepiness and improving overall quality of life.
