Overview

Idiopathic hypersomnia is a chronic neurological sleep disorder characterized by excessive daytime sleepiness that is not explained by another condition. People with the disorder experience an overwhelming need for sleep during the day despite adequate or prolonged nighttime sleep, and they often have great difficulty waking, marked grogginess on waking known as sleep inertia, and unrefreshing naps. The term idiopathic indicates that the underlying cause is unknown, distinguishing the condition from hypersomnia due to other sleep disorders, medications, or medical illnesses. Diagnosis typically relies on clinical assessment together with sleep studies and tests of daytime sleep tendency, and the condition is differentiated from narcolepsy, with which it shares the feature of excessive sleepiness but differs in other respects. Within the field of sleep and sleep disorder research, idiopathic hypersomnia sits alongside related disorders of excessive sleepiness. The journal's coverage includes a systematic review of narcolepsy with and without cataplexy in the pediatric population, reflecting broader scholarly attention to disorders of hypersomnolence and their evaluation. This page gathers peer-reviewed, open-access research relevant to idiopathic hypersomnia and the wider study of excessive daytime sleepiness.
