Idiopathic hypersomnia (IH) is a chronic, neurological sleep disorder causing excessive daytime sleepiness despite getting normal or longer amounts of sleep, but the exact cause is not known. In celebration of IH Day (June 7, 2025), Project Sleep hosted a special Narcolepsy Nerd Alert broadcast shedding light on this rare condition, which shares similarities with narcolepsy but is less well-known.
Special guests Dr. Lynn Marie Trotti, MD, Claire Wylds-Wright, CEO of the Hypersomnia Foundation, and Rising Voices speaker Taylor Jackson shared clinical, advocacy, and patient insights on living with idiopathic hypersomnia.
