Hypersomnia, sometimes called excessive daytime sleepiness (EDS), is a sleep disorder characterized by extreme daytime sleepiness, even after sleeping six to seven hours or more. Some people with hypersomnia may sleep for very long periods. Symptoms usually appear between the ages of 17 and 24.1Miglis, Mitchell G., et al. ‘Frequency and Severity of Autonomic Symptoms in Idiopathic Hypersomnia.’ Journal of Clinical Sleep Medicine, 15 May 2020, jcsm.aasm.org/doi/10.5664/jcsm.8344

Primary hypersomnia may be described as idiopathic hypersomnia when symptoms occur without an identifiable cause. The disorder is referred to as secondary hypersomnia when it has a known cause. Secondary hypersomnia can occur as a side effect of certain medications or an underlying illness or injury. It may also be a response to stress or lifestyle.5‘About Idiopathic Hypersomnia.’ Hypersomnia Foundation, 4 June 2021, www.hypersomniafoundation.org/ih

Daytime Sleepiness

Excessive sleepiness during the day is the most prevalent symptom of hypersomnia. People may feel like they need to sleep, regardless of the time of day. This can be dangerous and may even lead to vehicle accidents if EDS occurs while driving. EDS episodes may interrupt meals or interfere with conversations and other social interactions.3‘Idiopathic Hypersomnia.’ Mayo Clinic, www.mayoclinic.org/diseases-conditions/hypersomnia/symptoms-causes/syc-20362332

Individuals with hypersomnia may take long naps during the day without feeling refreshed. EDS is sometimes associated with poor work or academic performance and may contribute to poor coordination, impaired motor skills and slow reaction times.5‘About Idiopathic Hypersomnia.’ Hypersomnia Foundation, 4 June 2021, www.hypersomniafoundation.org/ih
