Polysomnogram (PSG) – the “diagnostic sleep study”

Polysomnography is a series of comprehensive tests that are performed on patients while they sleep. It involves monitoring of the patient’s airflow through the nose and mouth, heart rate, blood oxygen level, brain wave patterns, eye movements and the movements of respiratory and limb movements. Sleep studies are pain free and are used to diagnose sleep disorders such as sleep apnea, narcolepsy, cataplexy and parasomnias. Sleep studies are also used to detect and evaluate seizure disorders, sleep related depression, and panic disorders.

CPAP/BiPAP/AutoSV Titration – the “treatment sleep study”

A titration study consists of all measures included in routine PSG as well as the application of nasal continuous positive airway pressure (CPAP) or intermittent positive airway pressure (BiPAP). Most people are familiar with CPAP, a device that produces air pressure using a soft and pliable nasal mask placed over the nose which provides mild pressure support to prevent the throat from collapsing throughout the night. Nasal CPAP and BiPAP pressures are adjusted throughout the night to determine the appropriate pressure(s) to be prescribed in treatment.

Multiple Sleep Latency Test (MSLT)

A MSLT routinely follows nocturnal polysomnography. A MSLT provides the patient with four or five scheduled opportunities to nap during the day. This is a routine test in the evaluation of daytime sleepiness. The mean latency to sleep onset for all naps is calculated as a measure of daytime sleepiness. A MSLT can be important in determining the severity of sleep apnea or your response to treatment. A MSLT is also used to detection of rapid-eye-movement (REM) sleep episodes during each nap. This could lead to a diagnosis of narcolepsy.

Maintenance of Wakefulness Test (MWT)

The MWT is a test used to determine an individual’s ability to remain awake when placed in an environment that is conducive to sleep. The procedure is similar to the MSLT in that four or five test sessions occur throughout the day. However, each test challenges the individual’s ability to remain awake while lying supine in a darkened room. The MWT may be used to determine response to treatment, and may provide documentation of a person’s ability to remain awake in critical situations.

Home Sleep Test

Using a home sleep test for the diagnosis of obstructed sleep apnea (OSA) should be performed in conjunction with a comprehensive sleep evaluation. Clinical sleep evaluations using home sleep tests must be supervised by a practitioner that is board certified in sleep medicine. Patients appropriate for home sleep testing should have moderate to high risk for OSA, have no comorbid conditions and no comorbid sleep disorders. Patients that do not qualify for home sleep testing should have an in-laboratory polysomnography (PSG). In-laboratory PSG is also the standard in patients with other sleep disorders, such as narcolepsy and central sleep apnea. At this time, home sleep testing has only been approved for adult patients.

Routine Electroencephalogram (EEG)

EEG (or electroencephalography) is a painless test that records electrical signals produced on the surface of the brain. EEG helps physicians in the diagnosis of numerous neurological problems, such as epilepsy, strokes, and degenerative diseases. The EEG is also used to look for organic (physical) causes of psychiatric symptoms and disabilities, like seizures.

Video EEG/Seizure monitoring – long term monitoring (12 – 24 hours)

For long term monitoring EEG, a patient undergoing EEG is also simultaneously recorded on video and audio. A family member or friend who is familiar with the patient’s seizures will need to stay with the patient. That person will be asked to alert the EEG technician at the first sign of a seizure. The technician will make sure that the patient is safe, preserve lead placement, observe clinical events and then test for language, memory, and ability to follow commands. A long term EEG monitoring test should be considered to a) evaluate/characterize particular events (e.g. staring) or states (e.g. sleep) of interest for seizures; or b) sample multiple EEG discharges to determine an anatomic site of EEG discharge.
