« Back to Glossary Index

Hypersomnia refers to the condition of sleeping excessive amounts. However, in current medical terminology, both “hypersomnia” and the related word “hypersomnolence” are used more broadly to indicate long sleep durations, excessive daytime sleepiness, or both. In some classification systems, “hypersomnia” is reserved to refer to a specific disease entity, such as idiopathic hypersomnia, while “hypersomnolence” refers to the symptoms of long sleep and/or excessive daytime sleepiness regardless of cause. For more details, see Classification of Hypersomnias.
