Idiopathic Hypersomnia

Idiopathic hypersomnia is a sleep disorder characterized by excessive daytime sleepiness despite getting enough hours of sleep, without an identifiable cause to explain it.

How it shows up: persistent difficulty staying awake, naps that aren't restorative, and, at times, a prolonged sense of grogginess upon waking.

When to seek care? When daytime sleepiness interferes with school, work, or driving safety, it's a good idea to bring it up with a professional to rule out other causes.

Which specialist treats it? A general practitioner can provide initial guidance, and depending on the situation, psychiatry or, in children, pediatrics may be involved. It's worth having the case evaluated by a professional who can thoroughly study the sleep pattern.
