Common sleep disorders

Here are some common sleep issues that can interfere with the ability to achieve quality sleep:

  • REM behavior disorder

    is a condition that can cause someone to act out vivid or even violent dreams during rapid eye movement stage sleep.
  • Nightmares/night terrors

    are dreams or partial waking from sleep characterized by behaviors such as sleepwalking, screaming, kicking and thrashing.
  • Snoring is one of the most common sleep disorders. Sometimes snoring is a symptom of sleep apnea.
  • Sleep apnea is a condition where breathing essentially stops during sleep. It is characterized by loud snoring with gasping, snorting or pauses in breathing. Individuals who suffer from sleep apnea often complain of excessive daytime sleepiness.
  • Insomnia is a condition that makes it difficult to fall asleep or stay asleep. Factors such as stress or depression can contribute to or worsen insomnia.
  • Narcolepsy causes overwhelming sleepiness and uncontrolled bouts of sleep.
  • Restless leg syndrome is a condition where patients complain of a twitching or crawling sensation in one or both of their legs, making it difficult to fall asleep or stay asleep.
  • Circadian rhythm disorders affect the timing of sleep. People with circadian rhythm disorders are unable to sleep and wake at times required to fulfill normal work and social schedules.
  • Gastroesophageal reflux disorder, or GERD, is a disorder that causes heartburn symptoms which can worsen at night.
  • Jet lag is a form of circadian rhythm disorder most commonly caused by rapid long-distance east-west travel.
  • Central sleep apnea causes the brain’s respiratory control centers to become imbalanced during sleep, affecting the rate of respiration.
  • Cheyne-Stokes respiration, also known as periodic breathing, is characterized by an abnormal pattern of breathing during sleep.
  • Sleep deprivation, also called insufficient sleep syndrome, is a condition when someone habitually fails to obtain sufficient sleep.

Sleep studies and procedures

The first step in solving a sleep/wake disorder is determining what happens while you are asleep. At The Sleep Center at HCA Houston Healthcare Medical Center, we offer a range of treatment programs to increase our success in treating various sleep disorders. Some of the services we offer are:

  • Sleep study, or nocturnal polysomnography, is the most common type of study conducted for the diagnosis of sleep disorders. The test measures brain waves, eye movement, muscle movement, respiratory airflow, respiratory effort, oxygen saturation, snoring, heart activity, arm and leg movement and body position. This information is collected for six to eight hours and is analyzed to note any patterns or behaviors that are impacting sleep.
  • Multiple sleep latency test is used to determine how fast you fall asleep in the dark. The test consists of a series of 20 minute naps in two hour intervals throughout the day.
  • CPAP test is a treatment for sleep apnea that supplies continuous positive airway pressure. A second sleep study is conducted, wearing the device.
  • BiPAP test is similar to CPAP but provides two levels of pressure, inspiratory positive airway pressure and a lower positive airway pressure for easier exhalation. A BiPAP test is conducted in the same manner as a CPAP test.
  • Adaptive servoventilation (ASV) is a device used to treat central and complex sleep apnea. This unit has the ability to adapt to individual breathing patterns, adjusting to what a patient needs based on his or her breathing and need for support during respiratory events.
  • Oxygen therapy is used to maintain safe oxygen levels during sleep. It is sometimes indicated for patients whose blood oxygen remains low following other treatments.
  • Electrocenphalogram (EEG) is a test for recording the electrical activity produced by the brain. The EEG procedure provides information about brain function, which can help to evaluate problems that are inhibiting quality sleep. During this painless procedure, small electrodes are attached to the scalp with a water-soluble paste.
  • End tidal CO2 monitoring is a non-invasive test for measuring the volume of exhaled carbon dioxide that is formed during respiration. This test is helpful in assessing breathing issues during sleep.

Preparing for your sleep study

During a sleep study, we monitor your sleep and breathing in order to determine if a sleep disorder is present. We encourage you to approach your sleep study as if you are going to have a regular night’s sleep. You may bring any items you normally use to ensure a restful night’s sleep.

Your sleep study will take place in a private room that looks very much like a bedroom or hotel room. The temperature and lighting will be set to levels conducive to a restful night’s sleep.

Here are some instruction to follow prior to your sleep study:

  • Please bring your photo I.D. and your insurance card.
  • Try not to take naps during the day of your visit.
  • Please refrain from ingesting caffeine for eight hours prior to your sleep study. Caffeine is a stimulant found in coffee, tea, soda and other products.
  • Please refrain from consuming alcohol on the day of your study. Alcohol is a depressant.
  • Take medications as usual unless otherwise instructed by your physician.
  • Ask your doctor prior to taking any medicines intended to help you sleep as these may interfere with the results of your test.
  • Bring something comfortable to sleep in, such as pajamas.
  • You may bring your own pillow if you feel it will make you more comfortable.

Sleep disorders at HCA Houston Healthcare

Sleep disorders refer to a change or disturbance in a patient’s normal sleep pattern. Sleep disorders may affect the amount of sleep and quality of sleep someone receives. Sleep timing may also be of concern in the case of disorders like narcolepsy. Sleep disorders can be linked to both medical and emotional causes.
