There are more than 80 different types of sleep disorders, most of which can be classified as insomnia, excessive daytime sleepiness, sleep rhythm problems or sleep-disruptive disorders. Specific types treated at Newton Medical Center’s Sleep Diagnostic & Treatment Center include:
- Snoring – Best recognized as a loud, hoarse breathing sound that occurs during sleep, snoring can be caused by abnormalities of the nose and throat, such as nasal polyps, enlarged tonsils or adenoids, or a deviated nasal septum. Although common, snoring may also be a symptom of sleep apnea.
- Sleep apnea – People with sleep apnea stop breathing repeatedly during sleep, sometimes as many as hundreds of times, for a minute or longer. There are three types:
- Obstructive sleep apnea – This is the most common apnea and is often caused by a blockage of the airway, usually when the soft tissue in the rear of the throat collapses and closes during sleep.
- Central sleep apnea – The airway is not blocked, but the brain fails to signal the muscles to breathe.
- Mixed apnea – This condition is a combination of obstructive and central sleep apnea.
- Narcolepsy – A disorder caused by the brain’s inability to regulate sleep-wake cycles normally, resulting in excessive daytime sleepiness, sudden sleep attacks, insomnia and dream-like hallucinations.
- Restless Leg Syndrome (RLS) – This condition causes uncomfortable leg sensations, such as a creeping or crawling feeling, burning, tingling or cramping that occur continually while the body is at rest.
- Periodic Leg Movements in Sleep (PLMS) – A disorder in which the legs twitch or go through repetitive movements every 20 to 40 seconds during episodes lasting a few minutes to several hours while sleeping. Patients are often unaware that this is happening, but complain of symptoms such as insomnia, excessive daytime sleepiness or feeling tired upon waking.
