Causes, incidence, and risk factors: Some people�have an irregular sleep-wake pattern because of a problem with�brain function, the body's�circadian pacemaker (internal clock),�or�other reasons.� In other people, such as shift workers and travelers who change time zones frequently, outside factors cause this syndrome.
Signs and tests: Individuals with irregular sleep-wake syndrome may complain of either insomnia or excessive sleepiness. Patients usually have�an irregular pattern of at least three sleep episodes during a 24-hour period. The total amount of time a person with this condition sleeps is considered normal for their�age. No medical or mental disorder�causes the symptoms, and no other sleep disorder is generally present.
