The most common<unk> es are: Polysomnogram Polysomnography records several body functions during<unk> , including brain activity, eye movement, oxygen and carbon dioxide blood levels, heart rate and rhythm, breathing rate and rhythm, the flow of air through the mouth and nose, snoring, body muscle movements, and chest and belly movement. These tests are typically done at night in a hospital or<unk>  center. Polysomnogram tests can give insight into what issue is occurring. Multiple<unk>  latency test (MSLT) The MSLT measures, by several nap opportunities in one day, how long it takes a person to fall<unk> . It also determines whether REM<unk>  appears upon falling<unk> . It is usually performed immediately after an overnight<unk> . This test is the standard to test for narcolepsy and idiopathic hypersomnia. Maintenance of wakefulness test (MWT) This test measures whether a person can stay awake during a time when she or he is normally awake. Like the MSLT, the MWT is performed in a<unk>  diagnostic center over 4 - 5 nap periods. A mean<unk>  onset latency of less than 10 minutes is suggestive of excessive daytime<unk> iness. Home<unk>  test (HST) These typically include the individual whose<unk>  is being<unk> ed receiving a portable monitor and may include other items such as a finger clip and an airflow sensor. Items measured include oxygen saturation, heart rate, airflow, body movement, time spent snoring,<unk>  position, and brain waves.<unk>  Questionnaires * Tayside children's<unk>  questionnaire: A ten-item questionnaire for<unk>  disorders in children aged between one and five years old. * Children's<unk>  Habits Questionnaire. * Cleveland Adolescent<unk> iness Questionnaire (CASQ): There are 16 items to measure extreme<unk> iness during the day in adolescents aged 11–17 years old.
