Sleep-wake syndrome - irregular
People with irregular sleep-wake syndrome may have insomnia, excessive sleepiness, or both. Patients usually have at least three abnormal sleep episodes during a 24-hour period, but their total amount of sleep time is normal for their age.
If the diagnosis is not clear, your health care provider may prescribe a device called an "actigraph" for you to wear. This looks like a wristwatch, and can tell when you are sleeping or awake.
