7 listed sites on this page do not say which state they are in, so the counts above are lower than the real number of sites in some states. The trials themselves are all listed below.

Trials for Sleep Disorders

34 of 34 trials shown.

This Australian count is likely to be on the low side. It counts the trials this site files under this condition; the registry’s own search is broader and also returns closely related conditions, some of which have their own page here. If you are searching widely, check the registry as well — every trial below links to its own record.

Trials not shown here

Some Australian trials are registered only on the Australian New Zealand Clinical Trials Registry and are not shown here. Search them at Australian Clinical Trials.

Trials overseas

1,892 trials for this condition are open to new participants outside Australia, as ClinicalTrials.gov listed them on 11 October 2026. Voxsanity does not publish a page for any of them; the searches below reach them at the registry.

These overseas counts are likely too high. They come from the registry’s own search, which expands a condition name to related conditions, so some of the trials counted are for a different disease in the same family.

About Sleep Disorders

The text below is reproduced exactly as its source published it. It has not been edited, shortened or rewritten.

What is sleep? While you are sleeping your brain and body functions are still active. Sleep is a natural process that helps your body restore energy, supports learning and memory, and keeps you healthy. It's not just the number of hours of sleep you get that matters. The quality of your sleep is also important. During the night, your brain cycles through different stages of non-rapid eye movement (non-REM) sleep and rapid eye movement (REM) sleep. If your sleep is often interrupted, you may not get enough time in certain stages of sleep. Poor-quality sleep does more than make you feel tired. It can affect your physical and mental health, thinking, and daily functioning. What are sleep disorders? Sleep disorders are conditions that disturb your normal sleep patterns. There are many types of sleep disorders. Some general types include: - Insomnia, which is trouble falling asleep or staying asleep. - Sleep-related breathing disorders such as sleep apnea, a condition in which you stop breathing for 10 seconds or more during sleep. - Sleep-related movement disorders such as restless leg syndrome (RLS), which involves tingling or prickling sensations in your legs, and a strong urge to move them. - Hypersomnia, which is extreme daytime sleepiness. This includes narcolepsy. - Circadian rhythm sleep-wake disorders, which are problems falling asleep or waking up at the right times. This may be due to shift work or jet lag. - Parasomnia, which is unusual behaviors during sleep or while falling asleep or waking up. This may include sleepwalking, talking, or eating during sleep. Some people who feel tired during the day have a true sleep disorder, while others simply don't get enough sleep. The amount of sleep you need depends on your age, lifestyle, health, and sleep patterns. Most adults need about 7-9 hours each night. What causes sleep disorders? There are different causes for different sleep disorders. They may include: - Other health conditions, such as heart disease, lung disease, nerve disorders, or pain - Mental illnesses, including depression and anxiety - Medicines - Genetics Sometimes the cause is unknown. Other factors that may contribute to sleep problems include: - Using caffeine or alcohol - Having an irregular schedule, such as working the night shift - Aging, since older adults may sleep less, spend less time in deep sleep, and wake easily What are the symptoms of sleep disorders? The symptoms of sleep disorders depend on the specific disorder. Some signs that you may have a sleep disorder include that: - You regularly take more than 30 minutes to fall asleep. - You regularly wake up several times and then have trouble falling back to sleep, or you wake up too early in the morning. - You often feel sleepy during the day, take frequent naps, or fall asleep at the wrong times during the day. - Your bed partner says that when you sleep, you snore loudly, snort, gasp, make choking sounds, or stop breathing for short periods. - You have creeping or tingling sensations in your legs or arms that are relieved by moving or massaging them, especially in the evening and when trying to fall asleep. - Your bed partner notices that your legs or arms jerk often during sleep. - You have vivid, dreamlike experiences while falling asleep or dozing. - You have episodes of sudden muscle weakness triggered by strong emotions. - You feel as though you cannot move or speak for a brief time when you first wake up. How are sleep disorders diagnosed? To diagnose a sleep disorder, your health care provider will review your medical and sleep history and do a physical exam. You may also have a sleep study (polysomnogram). Most sleep studies monitor and record data about your body during a full night of sleep. The data includes: - Brain wave activity - Eye movements - Breathing rate - Blood pressure - Heart rate and electrical activity in the heart and other muscles Other types of sleep studies may check how quickly you fall asleep during daytime naps or how well you can stay awake during the day. What are the treatments for sleep disorders? Treatments for sleep disorders depend on which disorder you have. They may include: - Practicing good sleep habits and other lifestyle changes, such as eating a healthy diet and getting regular exercise - Reducing anxiety about sleep with cognitive behavioral therapy or relaxation techniques - Using a CPAP (continuous positive airway pressure) machine for sleep apnea - Using bright light therapy (in the morning) - Taking sleep aid medicines, or natural products such as melatonin Always check with your provider before taking any medicine or supplement. Most sleep aid medicines are generally for short-term use.

Not medical advice.

Individual trial records are refreshed on a rolling basis rather than all at once, so a record may be up to several weeks old. Each trial page and trial card shows the date its own record was last synced. Where a record has lagged, its status, sites and enrolment can differ from the current registry state in either direction, so check the registry link on the trial page before acting on them.

Questions to ask your doctor

General questions, the same on every condition page. Print this page to take them with you.

Is a clinical trial something I should consider at this point?
What would taking part involve week to week?
What are the risks, and what happens if I change my mind?
Would being in a trial change the care I get now?
Who would I see, and how far would I need to travel?
Are there costs, and is travel or time off work covered?
Can you refer me, or do I contact the trial site myself?

Is a medicine on the PBS?

Search the PBS on the Pharmaceutical Benefits Scheme's own website. Voxsanity does not publish PBS listings.
