Sleep Disorders Center

The Southern Illinois Sleep Disorders Center specializes in the diagnosis and treatment of sleep apnea and other sleep-related disorders.

A number of different symptoms may suggest a sleep disorder, including:
  • Excessive daytime sleeping
  • Involuntary dozing during the day
  • Difficulty falling or staying asleep
  • Unusually loud snoring
  • Kicking movements of the legs during sleep
  • Decreased memory or concentration
  • Depression
  • Sensation of leg restlessness
Sleep disorders affect millions of Americans, but too often they go unrecognized by both patients and physicians. As many as one third of all adults experience insomnia, and two to four percent of middle-aged adults may have significant breathing disorders during sleep. Other less common sleep disorders include narcolepsy, nocturnal movement disorders, and sleep-walking or other unusual behaviors.

Untreated sleep disorders can have significant medical and social consequences. Excessive sleepiness may impair work efficiency, affect mood and increase the risk of injury on the job or while driving. Sleep-related breathing disorders are associated with high blood pressure, heart disease and stroke.

Diagnosing sleep disorders

The Southern Illinois Sleep Disorders Center offers a comprehensive evaluation of patients with sleep-related complaints. After an evaluation by one of the Sleep Center physicians, patients may be referred for an overnight sleep study. In some cases, additional day studies may be needed as well. Sophisticated diagnostic equipment is used to non-invasively monitor brain, heart, respiratory and muscle activity during sleep. Most insurance companies provide coverage for these studies.

Treatment for sleep disorders

Most sleep disorders can be successfully and safely treated. Depending on the diagnosis, treatment may include continuous positive airway pressure (CPAP) therapy for breathing disorders, medication, behavioral modification, or consultation with another medical specialist, such as an ENT physician.
