Types of Sleep Disorders and Associated Tests

Suffering from sleepless nights? Learn more about potential disorders that may be disturbing your sleep.

At Health City Cayman Islands, we are passionate about evaluating and treating sleep disorders, with the goal of restoring healthy sleep patterns. When sleep disorders and their underlying causes are treated, patients find that their quality of life remarkably improves. In fact, patients who have undergone treatment at our sleep lab have reported significant improvements in energy levels, concentration, and performance. Treating these disorders can boost immunity and help prevent several chronic diseases linked to sleep deprivation. These include heart disease, stroke, diabetes, high blood pressure, kidney problems, depression, obesity, and dementia in older adults.

Signs of a Sleep Disorder

While some people are acutely aware that they are experiencing insomnia, people with other sleep disorders are often unaware that they have a problem. Here are some potential signs:

    • Snoring that disturbs your bed partner
    • Trouble falling asleep at night more than three times a week
    • Waking up frequently during the night
    • Feeling irritable or tired throughout the day
    • Falling asleep while driving, at work, or in the classroom
    • An itchy, crawly feeling in your legs
    • Waking up with a headache or a dry/sore throat


Sleep Disorders

There are more than 84 identified sleep disorders, but rest assured, our dedicated sleep lab team can help you get to the root of the issue and offer solutions.

The most common sleep disorders include:

Obstructive sleep apnoea (OSA)

Types of Sleep Tests

There are different types of Sleep Studies carried out in both lab and in-home settings to identify and monitor patient’s sleep patterns. Gold Standard Level I Sleep Studies are conducted in a lab setting, and include:

  • Diagnostic Sleep Study
  • Titration Sleep Study
  • Split Night Sleep Study
  • MSLT and MWT.

Level II Sleep Studies, also considered Gold Standard, are done in an in-home setting by using a portable device to capture many of the same parameters as a Level I study. Each study is designed to record a combination of different parameters during sleep, which can include: Brain wave activity, Respiratory pattern, Heart rate, Chest movement, Leg movement, Eye movement, and / or Blood Oxygen Saturation.

Nocturnal Polysomnography (diagnostic)
Nocturnal Polysomnography with Nasal Continuous Positive Airway Pressure (CPAP)
Split-Night Polysomnography
Nocturnal Seizure Recording
Multiple Sleep Latency Test (MSLT)
Maintenance of Wakefulness Test (MWT)
Home Sleep Testing (Level II & Level III)

There is no need to suffer from sleepless nights that are negatively impacting your life. We are committed to giving you the peace of mind that comes with a good night’s rest. Although most patients will stay overnight, home sleep studies using a portable monitoring system are an option.
