What is idiopathic hypersomnia
Idiopathic hypersomnia (IH) is a chronic neurological disorder that results in daytime sleepiness, difficulty in awakening and cognitive dysfunction.
Narcolepsy is often poorly understood, which can lead to difficulties and delays making the diagnosis. Treatments are often partially effective, so people with narcolepsy will usually have ongoing symptoms that impact on their daily life and need understanding and support of family, friends, employers and health professionals to function at their best.
