Explanation of Procedures
Below, you can learn everything you need to know about your sleep study.
An overnight Sleep Study is a painless and very important test to diagnose disorders related to sleep, such as stop breathing in sleep, snoring, awakenings or difficulties falling back to sleep, heart irregularities, muscle pain, bad dreams, unusual behavior in your sleep and many others ( there are 83 sleep disorders identified). A Sleep Study test is crucial in helping to develop the right treatment.
The all-night Sleep Study (Polysomnography test from 9:00p.m. to 7:00 a.m. the next day) is a non-invasive recording of multiple body functions during sleep, (poly means many, somno means sleep, graphy means recording). The Polysomnography will record your brain wave patterns (EEG), muscle movements and movements of your eyes, the amount of oxygen, nose, mouth , an abdominal breathing, your leg movements and your heart rate in sleep. These functions are analyzed separately and in their interactions.
For patients with Sleep Apnea Syndrome (stop breathing in sleep), CPAP is the best treatment. CPAP stands for Continuous Positive Airway Pressure. The CPAP machine consi sts of a machine with a humidifier, which produces air that flows through a mask into the nose with a specified pressure. Titration means careful and precise measurement of the necessary pressure.
For people who have excessive daytime sleepiness and fatigue, a Multiple Sleep Latency Test (MSLT) is a necessity. This test objectively measures the level of sleepiness and is performed in the morning, usually following the Sleep Study. The MSLT consists of four to five 20 minute naps followed by periods of alertness.
The day before your test, our staff will call you to confirm your appointment and ask i f you have any additional questions. NOTE: We ask that you contact our office at least 24 hours prior to the test if you need to CANCEL or reschedule.
Take all the medications that you usually take at the prescribed times. Bring any nighttime medications or medications for the next morning with you.
Typically, no sleeping pills will be given to you. If necessary, a mild medication for sleep, such as Benadryl or Ambien can be given with the doctor’s permission.
Inform the technician if you have any special needs, medical conditions or allergies, diabetes, asthma, etc. Inform the technician about your preferable bed time and wake time.
What to Bring
Most patients get adjusted to the sensors and wires easily. You will be able to move a round in sleep and adjust your sleeping position. In the morning all electrodes will be removed. You will have an opportunity to comment on the technician and other issues of the study by completing the Morning Report form.
Your doctor will receive the results of the Sleep Study, interpretations and recommendations, within 5-7 business days by fax. We encourage you to contact your Doctor for a follow-up appointment or schedule a follow-up visit with our staff Physician to go over the findings of the study.
All insurance companies, including Medicare and Medicaid, cover sleep studies. (Note: If you have an HMO, you must get a referral from your Primary Care Physician.) Financial arrangements are available.
You need to be at the Sleep Center at 9:00 p.m.
Encephalogram (EEG) – is a standard non-invasive medical procedure of recording bioelectrical brain activity through electrodes attached to surface of the skin on your head.
EEG test could reveal different abnormalities in the brain functions like hidden seizures causing headaches, behavior problems, and other symptoms.
EEG analysis could uncover potential problems in the right – left brain coordination, which might be an underlying cause of learning disabilities and autistic spectrum disorders.
EEG is able to uncover the levels of the so called “brain tone” similar to muscle tone. Changes in the brain tone could explain the cause of chronic fatigue, depression, hyperactivity, and attention deficit disorders.
During the EEG several functional tests are performed, such as hyperventilation (fast breathing) and stimulations with light flashes. These tests uncover how the brain responds to stress (adequate or inadequate; too intense or too slow; fast or delayed. The results are usually correlated with many psychological conditions in real life situations.
As you know, mental and emotional symptoms are based on changes in the brain function. EEG is one of these medically necessary and routine tests to measure the brain function, similar to EKG tests measuring the heart function. As described above, EEG will help to uncover the biologic causes of many psychological and psychosomatic problems, thus helping to direct the most appropriate treatment. EEG is also a good tool not only for diagnosis but also for treatment control.
You do not need any special preparation in terms of food or medications. Do everything as you usually do and take your medications as you usually take. The only two exceptions: 1. Please, wash your hair but do not use any hair products before the test. 2. Do not take stimulants or sedative/pain medications unless indicated by a physician.
During the procedure the skin on your head will be prepared with gel and multiple electrodes will be attached on your skull using a non-allergic cream. In addition three electrodes will be placed on your chest for simultaneous recording of your heart rhythm (EKG). You will be in a sitting or lying down positions in a dark room and will be asked to open and close your eyes, and breathe fast for a few minutes. At some point you will experience light flashes with different frequency, then you will be asked to relax with eyes closed. At all times you will be observed through audio/visual circuit by a technician and you will be able to communicate any feelings or questions. The procedure lasts about 90 minutes. The results will be available within 3- 4 days and will be discussed with you on the next appointment.
If you have any questions or concerns, please do not hesitate to contact our office.
