Diagnosing and treating sleep disorders with a sleep study

Here's how to inoculate ourselves against negative ones. Verified by Psychology Today. Brain Babble. Perhaps you or a loved one has been referred to a sleep clinic for insomnia , apnea, narcolepsy, or restless legs syndrome. Or perhaps you're just looking for your next Halloween costume. Looks rather scary, right?

The Dreem headband has fewer and less intrusive sensors than a PSG, and the whole thing is designed to be comfortable enough for nightly use.

It has 4 EEG electroencephalogram sensors in the front and two in back to precisely measure brain activity, as well as a pulse oximeter to measure heart rate, and an accelerometer to measure how much you move around in your sleep. Several sections of waterproof foam and spring-mounted sensors keep the headband from pressing uncomfortably into your face.

To test whether it was possible for a headband to match the signal quality of a PSG, the Dreem study had 31 participants undergo a sleep study wearing both a Dreem headband and a traditional PSG getup. This test took place in a standard sleep clinic with regular sleep scientists, so there was no chance of bias from Dreem affecting the outcome.

The scientists compared the data derived from the Dreem headband and PSG based on breathing frequency, EEG signal, respiratory rate, and heart rate.

Across the board, the Dreem headband performed just as well as the PSG sensors in gathering vital sleep data.

However, there is more to a PSG than just picking up the brain signals, breathing, and heart rate. One of the most important aspects of a professional sleep lab study is reading the PSG results and determining what sleeping problems the patient might have.

Specifically, sleep scientists are trained to "score" a PSG by looking at the results chart and determining at what point a patient is going through different sleep stages. Instead of sleep scientists, the Dreem headband has an app with a highly advanced algorithm that maps sleep stages and gives the user information about their sleeping patterns.

Does an algorithm really have a chance against an expertly trained sleep scientist?

Dreem actually compared their algorithm to the scoring expertise of five sleep scientistsand it turns out that the Dreem app algorithm is just as accurate at reading sleep data.

If your doctor suggests you undergo a sleep study, or polysomnography, you may be wondering what is involved in this test and what to expect.

WebMD explains how sleep studies are conducted in order to diagnose and You'll be hooked up to equipment that may look uncomfortable.

Sleep studies help doctors diagnose sleep disorders such as sleep apnea, periodic limb movement disorder, narcolepsy, restless legs syndrome, insomnia, and nighttime behaviors like sleepwalking and REM sleep behavior disorder. Often these disorders cannot be identified with a normal office visit—your doctor needs to gather more conclusive evidence while you're asleep.

A sleep study is a non-invasive, overnight exam that allows doctors to monitor you while you sleep to see what's happening in your brain and body. For this test, you will go to a sleep lab that is set up for overnight stays—usually in a hospital or sleep center. A sleep study will also measure things such as eye movements, oxygen levels in your blood through a sensor—there are no needles involvedheart and breathing rates, snoring, and body movements.

Home sleep studies do not replace in-lab sleep studies (still considered the gold you will be given a home sleep study device and shown the simple hook-up. Your doctor may want you to have a sleep study if you have trouble falling asleep , wake up frequently, snore, or have other symptoms of a. For this test, you will go to a sleep lab that is set up for overnight stays—usually in a hospital or sleep center. While you sleep, an EEG monitors your sleep.

A sleep study is done in a room that is made to be comfortable and dark for sleeping. You'll be asked to arrive roughly two hours before bedtime.

Sleep study hook up

You can bring personal items related to sleep, and you can sleep in your own pajamas. Before you go to bed in the exam room, a technologist will place sensors, or electrodes, on your head and body, but you'll still have plenty of room to move and get comfortable.

Polysomnographic technologists monitor you during the night and can help you if you need to use the bathroom, for example. Many people wonder how they'll be able to sleep under these conditions.

Don't worry about this too much—a full night of sleep is not required to gather useful information from your sleep study. The data from your sleep study will usually be taken by a technologist, and later evaluated by your doctor.

Includes types of sleep studies, equipment used, preparing the patient and After you hook up the patient to the various sensors, you'll go into. Full night diagnostic sleep study. 2. Continuous Positive Airway Pressure (CPAP) titration study. 3. Split night study (Diagnostic+Titration on the same night). 4.

This may take up to two weeks, when you'll schedule a follow up to discuss the results. How Does a Sleep Study Work?
