REM sleep behavior disorder (RBD) is a sleep disorder in which a person physically acts out their dreams while in the rapid eye movement (REM) stage of sleep. During the REM phase, the muscles in the body usually enter a state of temporary paralysis, but in people with RBD, this paralysis is incomplete or absent, allowing them to act out their dreams, sometimes in violent ways. This condition can cause injuries to both the person with RBD and their bed partner. Symptoms of RBD can vary in severity and may include mild muscle twitches, shouting, punching, or falling out of bed. Treatment for RBD focuses on creating a safe sleeping environment and may involve strategies such as removing sharp objects from the bedroom and medication to manage symptoms.

Diagnosis: A doctor will refer you to a sleep physician for a physical and neurological exam, and possibly a sleep lab for a polysomnogram
If you think you may have REM sleep behaviour disorder (RBD), it is important to see a healthcare provider. They will ask you questions about your symptoms and medical history. If you have a bed partner or housemate, your doctor will likely ask them questions about your sleeping behaviour, as well.
Your provider will perform a physical and neurological exam. They may refer you to a sleep specialist or sleep physician for further examination. To receive a diagnosis of RBD, you will likely undergo an in-lab video sleep study, also known as a polysomnogram (PSG). Sleep studies are tests that record specific body functions during sleep, such as:
- Heart rate
- Breathing rate and airflow
- Brain wave activity
- Eye movements
- Muscle movements of your chin and upper extremities
Polysomnography is considered the single most important diagnostic test for RBD. This test is usually conducted in a sleep study centre, where the person undergoing testing is required to sleep while the following parameters are monitored:
- Electrical activity of the brain (electroencephalogram, or EEG)
- Electrical activity of the heart (electrocardiogram, or ECG)
These parameters are monitored as the person passes through the various sleep stages. Polysomnographic video recording will show body movements coinciding with the EEG pattern of REM sleep.

Treatment: Prescribed medication and adapting sleep habits can help manage RBD
REM sleep behavior disorder (RBD) is a parasomnia disorder that affects between 1 and 7% of adults, particularly older adults. People with RBD may unknowingly act out their dreams, causing injury to themselves or their bed partners. Treatment options for RBD are currently limited, but certain medications and sleep habits can help manage the condition.
Prescribed Medication
The most commonly prescribed medications for RBD are melatonin and clonazepam. Melatonin is a naturally occurring hormone that helps regulate sleep. In people with RBD, melatonin therapy may help to reduce the intensity of dream enactment episodes. Clonazepam is a benzodiazepine medication that has been shown to be effective in treating RBD symptoms in several studies. However, its long-term use may affect non-rapid eye movement sleep patterns. Other medications that have shown anecdotal efficacy in treating RBD include temazepam, lorazepam, zolpidem, and zopiclone.
A novel treatment approach involves the use of dual orexin receptor antagonists, which are typically used to treat insomnia. Research has shown that these medications can reduce the time it takes to fall asleep, improve sleep quality and duration, and decrease dream enactment behaviors.
Adapting Sleep Habits
In addition to medication, adapting sleep habits can also help manage RBD. A non-pharmacological approach is the use of a bed alarm system, which may be particularly useful for patients who sleepwalk or leave their bed during dream enactment. Additionally, the potential benefits of hypnosis in treating RBD, especially in those with psychiatric RBD, warrant further study.

Safe sleep environment: Removing sharp objects, placing pillows around the bed, and using a mattress on the floor can prevent injuries
REM sleep behavior disorder (RBD) is a sleep disorder in which people physically act out their dreams while in the rapid eye movement (REM) stage of sleep. They may talk, shout, kick, punch, jump, or fall out of bed. About 8 in 10 people with RBD experience sleep-related injuries. Creating a safe sleep environment can help prevent injuries and typically involves the following:
Removing Sharp Objects
People with RBD may unknowingly act out their dreams and injure themselves or their bed partners. Removing sharp objects from the bedroom can reduce the risk of injury. This includes objects made of glass or other heavy materials that could cause harm if knocked over or handled during an episode.
Placing Pillows Around the Bed
Placing pillows between the sleeper and surrounding structures, such as the headboard or nightstand, can help cushion any potential impacts and prevent injuries. Additionally, placing the bed against a wall can create a barrier to keep pillows in place and prevent them from falling behind the bed.
Using a Mattress on the Floor
Using a mattress on the floor instead of a bed frame has both advantages and disadvantages. On the one hand, it can provide a safer option for people with RBD, as it reduces the distance of a potential fall. It is also inexpensive and can open up space in small bedrooms. However, it may be problematic for people with mobility issues, as it requires more effort to get in and out of bed. Additionally, mattresses placed directly on the floor are more susceptible to insects, dust, and moisture, which can trigger allergies and respiratory issues.
Overall, creating a safe sleep environment for those with RBD can help prevent injuries to both the affected individual and their bed partner.

Sleep partner: If symptoms are severe, it may be safer for the sleep partner to sleep in a separate room
REM sleep behaviour disorder (RBD) is a sleep disorder in which a person physically acts out their dreams while being asleep, often in violent ways. The person is unaware of their actions during sleep and may talk, shout, scream, kick, punch, grab the air or their bed partner, or jump or fall out of bed. About 8 in 10 people with RBD experience sleep-related injuries, and the bed partner is also at risk of injury.
If the symptoms of RBD are severe, it may be recommended that the person with RBD and their sleep partner sleep in separate rooms. This is to ensure the safety of the sleep partner, as the person with RBD may act out violently during their sleep.
Creating a safe sleeping environment is crucial for both the person with RBD and their sleep partner. This can include removing sharp, glass, and heavy objects from the bedroom, placing pillows around the bed, and using a mattress on the floor next to the bed in case the person with RBD falls out of bed.
In addition to environmental modifications, medication may be prescribed to manage severe symptoms that do not respond to safety measures. Low doses of clonazepam, a benzodiazepine drug, can suppress muscle activity and relax the body during sleep, helping to prevent violent behaviour. Antidepressants or melatonin may also be effective in calming violent sleep behaviour.
It is important to consult a healthcare provider if you or your sleep partner exhibit symptoms of RBD. A physical and neurological exam will be conducted, and the provider may refer you to a sleep specialist for further evaluation, which may include an overnight sleep study.

Parkinson's disease: Doctors will also look for symptoms of Parkinson's, such as hand tremors or muscle stiffness
REM sleep behaviour disorder (RBD) is a sleep disorder in which one physically acts out their dreams while in the rapid eye movement (REM) stage of sleep. People with RBD may shout, kick, punch, thrash around in bed, or jump out of bed. These episodes can result in sleep-related injuries for the person with RBD or their bed partner.
If you suspect you have RBD, it is important to see a healthcare provider. They will ask you questions about your symptoms and medical history and may refer you to a sleep specialist. To receive a diagnosis of RBD, you will undergo an in-lab video sleep study, also known as a polysomnogram (PSG).
Now, onto the relationship between RBD and Parkinson's disease. RBD is often associated with Parkinson's disease, and doctors will look for symptoms of Parkinson's when diagnosing RBD. Parkinson's disease is a progressive condition that impacts complex movements. While there isn't a single test for Parkinson's, providers can typically make a diagnosis based on three signs:
- Resting tremor on one side of the body (asymmetric tremor)
- Slowing of movement on one side of the body (asymmetric bradykinesia)
- Improvement of symptoms with dopaminergic medication, a common Parkinson's treatment
However, early symptoms of Parkinson's can vary. Some people with early-stage Parkinson's may have tremors or slowed movement on both sides of the body, or they may not respond to dopaminergic medication. Additionally, some people with Parkinson's never develop tremors. Other early signs of Parkinson's disease include:
- Changes in handwriting (micrographia)
- Loss of sense of smell
- Stiffness in the body, arms, or legs
- Stooping, leaning, or slouching when standing
- Difficulty moving bowels without straining

Frequently asked questions
REM sleep behavior disorder (RBD) is a sleep disorder in which a person physically acts out their dreams while being unaware of their actions. This can cause injury to themselves or their bed partner, especially if they are acting out a violent nightmare.
The symptoms of RBD can vary in severity. A person with RBD may experience mild muscle twitches or limb movements, talk or shout in their sleep, kick or punch the air or bed partner, or jump or fall out of bed. More severe symptoms may include sleep-related injuries and acting out violent nightmares.
If you suspect you may have RBD, it is important to consult a doctor or healthcare provider. They will ask questions about your symptoms and medical history, and may also examine any sleep partners or housemates. A physical and neurological exam will also be conducted to rule out other potential causes, such as alcohol, medications, or narcolepsy. In some cases, you may be referred to a sleep lab for an overnight sleep study, where sensors will monitor your breathing, eye movements, body movements, brain and heart activity, and blood oxygen levels.
The main goal of treatment for RBD is to create a safe sleeping environment for both the affected individual and their bed partner. This may involve removing sharp or heavy objects from the bedroom, placing pillows around the bed, sleeping on a mattress on the floor, or using a sleeping bag. In some cases, medication may be prescribed to manage symptoms, such as low doses of clonazepam or certain antidepressants. It is also recommended to avoid alcohol, as it can trigger RBD episodes and make the condition worse.
