What Is Idiopathic Hypersomnia?

Idiopathic Hypersomnia (IH) is a chronic neurological sleep disorder, causing excessive daytime sleepiness despite adequate, or more typically, long sleep amounts (more than 9-10 hours in a 24-hour period). People with IH often struggle to wake, despite setting multiple alarms, and have difficulty rising from bed (called sleep inertia). They may start the day feeling extremely groggy (sometimes referred to as sleep drunk), and can experience significantly reduced focus and concentration during waking hours (called brain fog).

People suffering from idiopathic hypersomnia often live without a correct diagnosis for a long time, blaming themselves and struggling to maintain work, studies and relationships.
