Missoula Sleep Medicine Services

Providence Medical Group-Sleep Medicine helps diagnose, treat and follow a range of common sleep disorders. We maintain a sleep medicine lab at Providence St. Patrick Hospital and also conduct indicated tests at home. Examples of testing include polysomnography, home sleep studies, actigraphy, overnight oximetry, multiple sleep latency test (MSLT) and maintenance of wakefulness test (MWT). By partnering with experts across disciplines, our team is able to manage an array of sleep issues and interactions with overall health.  

A few common sleep disorder symptoms include:

  • Loud snoring
  • Interruptions in breathing
  • Disruptive movements during sleep
  • Restless, non-restorative sleep
  • Daytime sleepiness

Common sleep disorders

Insomnia is the inability to fall or stay asleep. Insomnia can be caused by a combination of psychological, biological, lifestyle and environmental factors.

Snoring is typically regarded as harmless. However, it should not be taken lightly. Snoring not only disrupts domestic harmony, it can also be a symptom of a more serious disorder known as obstructive sleep apnea.

Sleep apnea occurs when you repeatedly stop breathing for more than 10 seconds during sleep, depriving the heart, brain and other vital organs of oxygen. Sleep apnea causes fatigue and daytime sleepiness.

Night terrors and sleepwalking share common symptoms, including the fear of waking up somewhere besides your own bed. You may appear confused or disoriented. You may walk around or hide things. You probably won’t remember what you did when you wake up.

Restless leg syndrome (RLS) describes irresistible leg movements. It can be accompanied by a creeping sensation deep in the legs and arms. Periodic leg movements in sleep (PLMS) is a similar condition with repetitive leg movements lasting up to five seconds, occurring every 20 to 40 seconds. PLMS may disrupt sleep and cause drowsiness during the day.

Sleep/wake disturbances, such as those associated with jet lag or work-shift changes, are caused by jolts to the body’s biological clock. These issues may be relatively short-term, but they affect how you feel and function.

Narcolepsy is uncommon but can be dangerous. It involves daytime sleep attacks, loss of muscle tone and hallucinations while falling asleep.

REM behavioral disorder is characterized by vigorous, often dangerous, sleep behaviors accompanied by vivid dreaming. With normal sleep, you become paralyzed so you don’t act out your dreams. With REM behavior disorder, paralysis is absent, which may cause you to physically, often violently, act out your dreams.
