Sleep Disorders & Tests

Sleep Disorders We Study

Without proper sleep health issues arise and our quality of life is affected. Here are some of the disorders we can help you with at Sleep Services of Texas.

Sleep Apnea

Causes people to frequently “stop breathing” while sleeping. When breathing is restored, there is a “micro-wakeup” called an arousal. As a result of this arousal, sleep is interrupted many times during the night. Since this occurs during sleep, patients are not aware of these brief interruptions.

Restless Leg Syndrome (RLS)

Characterized by unpleasant sensations in the legs and an uncontrollable urge to move in an effort to relieve these feelings. RLS sensations are often described by people as burning, creeping, tugging or the feeling of insects crawling inside the legs.


Difficulty falling asleep or staying asleep, resulting in an inadequate length of sleep and/or poor quality of sleep.


A neurological sleep disorder characterized by sudden and uncontrollable sleepiness and frequent daytime sleeping.

PLMD (Periodic Limb Movement Disorder)

Repetitive, involuntary movement of legs, and occasionally arms, that usually begins when asleep. Patients with PLMD may have difficulty falling and remaining asleep or experience excessive daytime sleepiness.

REM (Rapid Eye Movement) Behavior Disorder

Characterized by acting out dreams that are vivid, intense, and violent. It can be hereditary and is usually seen in middle-aged to elderly people, more often in men.

Types of Sleep Tests

Sleep Services of Texas provides comprehensive sleep study diagnostics for a wide variety of sleep disorders.

Polysomnography (PSG)

An overnight test that measures multiple variables during sleep, including airflow through the nose and mouth, blood pressure, electrocardiographic activity, blood oxygen level, brainwave patterns, eye movement and movement of respiratory muscle and limbs. It also observes various sleep stages and body positions throughout the night.

CPAP Titration

Continuous positive airway pressure (CPAP) analysis involves placing a mask over the nose and applying mild air pressure on a continuous basis to help prevent snoring and apnea. The pressure is gradually titrated to determine the correct settings.

Split Night (PSG/CPAP)

Split night PSG is conducted when moderate or severe sleep apnea has been discovered or strongly suspected during the first part of the night’s study. The second half of the night is used to determine the necessary CPAP pressure required to alleviate apnea.

Maintenance of Wakefulness Test (MWT)

Used to measure how alert you are during the day, MWT shows whether or not you are able to stay awake for a defined period of time. This is an indicator of how well you function and remain alert in quiet times of inactivity.

Multiple Sleep Latency Test (MSLT)

The standard way to measure your level of daytime sleepiness. Also called a “nap test,” MSLT determines how quickly you fall asleep in quiet situations during the day. Excessive sleepiness is when you are sleepy at a time and place when you should be awake and alert.

Evaluation & Consultation

Meeting where we address your specific concerns, offer suggestions for improving sleep and determine if a sleep study is needed. If you suspect you have a sleeping disorder, contact us to schedule your evaluation & consultation.

Home Sleep Test (HST)

A home sleep test (HST) is a lot less complicated than a traditional in-center study. There are only three sensors involved: a nasal sensor, a chest band, and a finger clip.
