Electroencephlagram (EEG) An EEG test measures brain wave activity and is used to help diagnose and treat neurological disorders, including headaches and dizziness, seizure disorders, epilepsy, altered mental states, strokes and degenerative brain disorders. A neurology technician will apply electrodes to the patient’s scalp to obtain the electrical signals from the brain. The technician will then monitor the patient’s brain waves for a period of time.
Electromyogram (EMG/Nerve Conduction NC) An EMG/NC test evaluates muscle and nerve function. This test measures the electrical activity in nerves and muscles and helps to detect any disorders. An EMG is used to help diagnose and treat disorders such as carpal tunnel syndrome and neuropathy.
Evoked Potential (EP) This test records the electrical activity from the brain, spinal nerves and sensory receptors as they respond to external stimulation. It is used to diagnose and treat multiple sclerosis, brain tumors or lesions, Guillain-Barré Syndrome and other diseases.
Long Term EEG and Video Monitoring (LTVM) – During this test, a patient stays at the hospital to receive an extended EEG. While wearing electrodes, the patient stays in a room with a video camera. This allows the physician to witness all seizure-like activity and monitor the patient’s brain waves at the time of the episodes.
Sleep Study Overnight/Daytime
A Sleep Study, or Polysomnogram, is used to diagnose a variety of sleep disorders. Most often it is used to diagnose sleep related breathing disorders including sleep apnea. The patient is monitored by a trained Technician/Technologist in the Sleep Center. During the study breathing patterns, brain activity, muscle tone, heart rate, airflow, oxygen levels, and body movements are monitored, recorded and synced with a video for the physicians review. Most insurance companies require recordings to be at least 6 hours in length.
This study is used to define and set the appropriate CPAP/BiPAP (Continuous/BiLevel Positive Airway Pressure) pressure necessary to treat patients with obstructive sleep apnea. ASV (Auto Servo Ventilation) is the mode used when treating Central Sleep Apnea (apnea caused by the brain not the airway). This test is similar to a sleep study. The patient is monitored for 6 hours in the Sleep Disorders Center using the same devices in addition to wearing a PAP mask connected to a PAP machine for therapy.
A Splitstudy includes both a sleep study and PAP Titration in one night. The patient must qualify during the first few hours of this test for this type of study to be performed. To qualify, a technologist must see breathing events (airway collapsing) during sleep. This must be documented 30 or more times in a 2 hour period and have 3 additional hours to perform the PAP Titration during the night. When a patient qualifies, the first half of testing is diagnostic and the second half is a PAP Titration. If the patient does not qualify in the first part of a split study, PAP therapy is not started. In some cases when patients qualify for PAP therapy (over the course of the 6 hour recording), the doctor may order the patient to return to the Center for a full night of PAP Therapy.
OCST (OUT-OF -CENTER-SLEEP TESTING)
A home sleep test can detect obstructive sleep apnea (when the airway collapses during sleep) in adults. It involves the use of a portable-monitoring system that is small enough for you to use at home. The patient is scheduled, educated, and setup with the device in the Sleep Disorders Center, which takes approximately 30 min. The actual testing is done while at home. After testing the patient returns the device to the Sleep Disorders Center. The data is uploaded from the device and a report is prepared for the doctor to read.

MSLT (Multiple Sleep Latency Test)
MSLT is used to diagnose narcolepsy. It consists of 5 nap trials which will show us how quickly the patient falls asleep. It also documents if the patient is able to enter stage REM sleep. The test is ordered with a sleep study preceding to validate the patient’s nighttime sleep.
MWT (Maintenance of Wakefulness Test)
MWT is used to document the ability to remain awake for a defined period of time without distraction in a sleep environment. This test is ordered with a sleep study the night before to validate the patient’s nighttime sleep.
An Actigraphy Watch tracks movement and light lux and is used to help diagnosis Insomnia, sleep maintenance and Circadin Rhythm disorders. The device is worn as a watch on the wrist. The patient is asked to come into the Sleep Disorders Center for a 30 minute education and setup session. The actual testing is done while at home. Your physician may order this test anywhere from 3-14 days in length. The patient is also asked to keep a sleep log during this period. After testing, the patient returns the device to the Sleep Disorders Center where the data is uploaded from the device and a report is prepared for the doctor to read.
This service is offered to patients having difficulty with PAP Therapy. The patient will work one-on-one with a sleep technologist, using relaxation, deep breathing and desensitization techniques to try to become more comfortable with PAP therapy. The technologist will also check for leaks and make sure the mask is appropriately fitted. PAP Naps take approximately one hour to complete. This is a free service provided by the Sleep Disorders Center.
