Sleep Disorders Center

The Memorial Medical Center/Southern Illinois University School of Medicine Sleep Disorders Center has been fully accredited by the American Academy of Sleep Medicine (AASM) since 1993. The Sleep Disorders Center serves over 1,200 patients a year to diagnose and treat a variety of sleep disorders, the most common being obstructive sleep apnea, insomnia, and narcolepsy. We are dedicated to the highest quality patient care in sleep medicine.

What are sleep disorders?

More than 100 million Americans of all ages suffer from a sleep problem. Some of the more common sleep disorders are:

  • Sleep apnea - Signs and symptoms: Snoring, interrupted by pauses in breathing
  • Infantile apnea - Children who have problems sleeping
  • Narcolepsy - Undesirable sleepiness at inappropriate times
  • Periodic limb movements - During sleep or Restless leg syndrome
  • Insomnia - Difficulty initiating or maintaining sleep
  • REM sleep behavior disorder - Movement during sleep and acting out dreams

What is a sleep evaluation?

A sleep evaluation starts with an interview with a sleep medicine physician.  In this interview, a specialist will ask you questions about your sleep and medical history followed by a physical exam.

A sleep evaluation can be ordered by your physician to determine if you have a sleep disorder. With certain sleep disorders, a sleep study and other tests may be indicated.

What is a sleep study?

A sleep study is a test performed and monitored by specially trained staff that includes measurements used to identify the different sleep stages and to categorize sleep problems. This is done by monitoring your brain waves, muscle tone and oxygen levels while you sleep, as well as heart rate and breathing parameters.

The study is performed while the patient sleeps in a private room. It is usually done at night.

Specialty areas involved in diagnosing sleep disorders include: Internal Medicine, Family Practice, Pulmonology, Cardiology, Neurology, Psychiatry, Psychology and Otolaryngology (ENT) physicians.

In-lab study:

  • lasts about nine hours;
  • must be ordered by a physician; and
  • records valuable data needed to diagnose sleep disorders.

Home sleep test:

  • In special cases, home testing may be an option
