Sleep Center

If you’re having trouble sleeping or staying awake, you might have a sleep disorder. Lake Health’s Sleep Center offers treatments for most sleep disorders, but the first step is recognizing that a problem exists.

The sounds of a serious health problem

It’s quite common to snore, snort or whistle at night. However, loud snoring could be the sign of sleep apnea, a disorder in which you temporarily stop breathing while you’re asleep due to an obstruction in your upper airway.

Someone with sleep apnea could have numerous episodes during the night, with each one lasting about ten seconds to a minute. This can be quite serious and potentially life threatening. It restricts the amount of oxygen in the bloodstream, which can lead to high blood pressure, heart attack or stroke.

Sleep disorders require professional help

Many sleep disorders can lead to problems falling asleep, staying awake, or sleeping on a regular sleep-cycle pattern. If you’re concerned about your sleep, you should seek immediate medical attention.

If you suffer from any of these symptoms, you might need a sleep test:

  • Morning headaches
  • Severe snoring
  • Excessive sleepiness during the day
  • Frequent naps
  • Unexplained heart failure
  • Marked obesity
  • Heartburn, chest pain, chronic cough at night
  • Insomnia and narcolepsy
  • Leg movement during sleep
  • Sleep walking, sleep talking
  • Trouble falling asleep

The Sleep Center offers testing and services for the following problems:

  • Sleep-related breathing disorders
  • Neuromuscular disorders and sleep-related symptoms
  • Parasomnias such as sleep walking and sleep talking
  • Excessive daytime sleepiness and narcolepsy
  • Periodic limb movement disorders
  • Insomnia

Advanced help from a nationally accredited program

We offer over 15 years of experience diagnosing and treating a broad spectrum of sleep disorders. Our sleep center features quiet, comfortable private rooms where patients are monitored overnight for suspected sleep disorders.

Accredited by the American Association of Sleep Medicine, our center offers advanced monitoring and diagnostic technology as well as an expert staff of physicians board-certified in sleep medicine, professional registered polysomnography technicians, registered respiratory therapists, pulmonologists, otolaryngologists (ENT) and psychologists.

Studies performed

An overnight sleep test or polysomnogram helps identify sleeping disorders and measures various sleep stages. Small sensors on your head, face and body measure your brain waves, muscle movement, eye movement, breathing, heart rate, leg activity and snoring.

The test is used in conjunction with various sleep questionnaires, a health/medical history, observation, a sleep diary and the physician’s expertise to help reach a diagnosis and recommend appropriate treatment options.

Sometimes additional sleep tests are needed, including the multiple sleep latency test (MSLT) and the maintenance of wakefulness test (MWT). The MSLT helps evaluate and diagnose other sleep problems such as narcolepsy, excessive daytime sleepiness and cataplexy. The MWT is used to evaluate and diagnose sleepiness and alertness.
