This table can be helpful in thinking about which type of sleep disorder you may have. Because many researchers think IH without long sleep and NT2 may be the same disorder, we’ve placed them next to each other to help you compare them more easily.
The colors in the table show how common it is for people with that disorder to have that specific symptom. The legend tells you what each color means. For example, dark blue means people with that disorder almost always have that symptom. The numbers show what percent (how many people out of 100) of people have that symptom.
Excessive daytime sleepiness (EDS) — A strong daytime sleepiness or need to sleep during the day, even with enough sleep the night before
Brain fog — Feeling mentally sluggish or fuzzy, confused, forgetful, or unable to focus
Long sleep — Needing at least 11 hours of sleep per 24-hour period (including naps) or more than 9 hours at night (or whenever you sleep the longest)
