Sleep
Insomnia is a general term for difficulty falling asleep and/or staying asleep. Insomnia is the most common sleep problem, with many adults reporting occasional insomnia, and 10–15% reporting a chronic condition. Insomnia can have many different causes, including psychological stress, a poor sleep environment, an inconsistent sleep schedule, or excessive mental or physical stimulation in the hours before bedtime. Insomnia is often treated through behavioral changes like keeping a regular sleep schedule, avoiding stimulating or stressful activities before bedtime, and cutting down on stimulants such as caffeine. The sleep environment may be improved by installing heavy drapes to shut out all sunlight, and keeping computers, televisions and work materials out of the sleeping area.
Idiopathic hypersomnia
Currently, there is no cure for idiopathic hypersomnia. Also, because the underlying disease mechanism is not yet fully understood (see Causes), treatment efforts have usually focused on symptom management. Although there are several FDA-approved medications for use in narcolepsy, there are no FDA-approved medicines for idiopathic hypersomnia. Therefore, the wake-promoting medications used in narcolepsy are also commonly used off-label to help manage the excessive daytime sleepiness of idiopathic hypersomnia. "These treatments have not been studied to nearly the same extent in patients with idiopathic hypersomnia, and some patients with idiopathic hypersomnia do not achieve adequate control of symptoms with these medications."
