Improve Quality Of Sleep

REM Sleep Behavior Disorder

Many who suffer from RBD are prone to sleep deprivation, so it is essential to make good lifestyle choices so that they can avoid experiencing excessive daytime sleepiness.

Here are some lifestyle choices that you can make:

Exercise Regularly

Leading to the release of endorphins, which reduce symptoms of depression, exercise can enhance your mental health.

And it does not take long. Simply exercising for 30 minutes a day can provide a plethora of health benefits.

Maintain Proper Sleep Schedule

Our mind functions on the basis of ingrained habits. So if you sleep at the same time everyday, youll find it easier to fall asleep.

If you cant fall asleep quickly, then you can ask your doctor about melatonin supplements, which relax the mind and promote sleep.

Avoid Stimulants

Alcohol and caffeine can trigger and exacerbate symptoms of REM sleep phase disorder. Talk to your doctor about the drugs that youre currently taking, as a few drugs act as triggers for RBD.

Part of your treatment plan may include quitting these substances.

What Is The Naps Consortium

Rapid Eye Movement sleep behavior disorder is a sleep disorder in which people move and talk during their dreaming sleep. Many people with RBD develop another neurological disorder, usually Parkinsonâs Disease, Dementia with Lewy Bodies, or Multiple System atrophyâcollectively termed synucleinopathiesâwithin several years. Currently, there are no treatments to slow or prevent these neurodegenerative disorders however, there are some promising treatments on the near horizon. The goal of the North American Prodromal Synucleinopathy Consortium is to plan a clinical trial for treatments against neurodegenerative disorders in people with RBD. To prepare for a clinical trial, we are enrolling people with RBD in a registry, performing a standardized set of measurements about neurological functioning, and obtaining blood samples and other biomedical information. Ultimately, we hope to enroll our registry participants in a clinical trial for preventive treatments against synucleinopathies. Under certain circumstances, taking part in the NAPS study may initially require you to undergo clinical sleep study, also known as a polysomnogram, at a NAPS site to confirm the diagnosis of RBD. The study coordinator will let you know what may be required in your individual case. In such cases, your health insurance may be billed for that procedure.

The Rem Sleep Behaviour Disorderneurological Disorder Association

RBD has been reported in association with many aetiological categories of neurological disorders , including vascular lesions, tumours, demyelinating disease , autoimmune/inflammatory disorders and neurodegenerative disorders . Within the autoimmune/inflammatory disorder spectrum, RBD is often associated with narcolepsy and more recently has been reported with limbic encephalitis associated with voltage-gated potassium channel antibodies . These disorders may reflect autoimmune/inflammatory processes affecting the structures and pathways involved in RBD pathophysiology as shown in . Quantitative neuropathological studies in brainstem nuclei of autopsied patients with narcolepsy and limbic encephalitis associated with voltage-gated potassium channel antibodies, with and without RBD, could help delineate the key nuclei involved in human RBD.

How Is Rem Sleep Behavior Disorder Prevented

There is no known way to prevent RBD. Lifestyle factors such as stress which can sometimes cause other sleep disorders, do not appear to cause RBD. However, in the absence of proven preventive measures, doctors encourage good sleep habits and a healthy lifestyle to lessen RBD risk. Steps you can take to ensure better sleep include:

  • Stick to a regular sleep schedule
  • Dont eat or drink close to bedtime
  • Avoid stimulating activities 30 minutes before bedtime
  • Use your bedroom only for sleep
  • Keep your bedroom dark and cool
  • Get plenty of exercise
  • Limit consumption of caffeine and alcohol
  • Quit smoking

When To Talk To Your Doctor

Diagnosis Of Rem Sleep Behavior Disorder

After learning about your symptoms, your medical history, and that of your family, the doctor may order a sleep study.

Sleep study for RBD requires you to sleep for one night at a sleep laboratory. Machines are hooked to your body to record your:

  • Blood oxygen level
  • Brain activity
  • Muscle movement

If youve RBD, then the sleep study will show an absence of muscle paralysis during the REM sleep phase.

How Is Rbd Diagnosed

It can be difficult to diagnose RBD. This is because its symptoms are similar to other parasomnias. For this reason a formal sleep study is necessary. This will require an overnight stay in a sleep center. During a sleep study sensors will monitor the patients heart, brain, and lung activities. Sensors will also monitor the patients breathing patterns and blood oxygen levels. Medical technicians will also monitor the patients arm and leg patterns as well as vocalizations. It is not unusual for a videotape to record the patients behavior during this test. This will allow a doctor to review the patients actions during REM sleep cycles.

How To Treat Rem Sleep Behavior Disorder

Safety measures need to be addressed first. Some bedroom safety precautions include:

  • Moving objects away from your bedside, including nightstands, lamps, or other objects that could cause injury.
  • Moving your bed away from windows.
  • Placing a large object, like a dresser, in front of windows.
  • Storing any objects that can be used as weapons.

Any factors known to aggravate RBD symptoms should be avoided or treated. Your treatment plan may include:

  • Maintaining a normal total sleep time. Sleep deprivation will increase RBD.
  • Avoiding certain medications and alcohol. They can cause or increase RBD.
  • Treating all other sleep disorders that disrupt your sleep and increase RBD. Untreated sleep apnea may worsen RBD symptoms.
  • Regular monitoring for any neurologic symptoms, such as tremors or other Parkinson symptoms.

RBD tends to respond to treatment with medications. Your sleep doctor can prescribe the medications that are appropriate for you.

Diagnosing Rem Sleep Behavior Disorder

Violent dreams: Diagnosing REM sleep behavior disorder

To diagnose this condition, you should talk with a sleep specialist. Your doctor will need to know your medical history and will perform a neurological exam. Your doctor may even refer you to a neurologist for more comprehensive testing.

Your doctor may monitor your sleep patterns by asking you to keep a sleep diary. They may also ask you to fill out the Epworth Sleepiness Scale. This scale can help them determine how your sleep patterns are interfering with your daily life.

You may be asked to perform an overnight sleep study. In this case, you will sleep in a laboratory attached to a heart rate, brain wave, and breathing monitor. These monitors will record your sleep stages, how you move throughout the night, and if you have any other disorders that may be affecting your sleep.

Rbd Can Be An Early Indicator Of Parkinsons

Research shows that up to 80% of people with RBD will develop a neurodegenerative disorder within ten years. As research into preventative measures increases, this may be an important early marker to increase the efficacy of a Parkinsons vaccine.

Restful sleep is important in general, but it is especially important for the quality of life of people living with Parkinsons.

RBD can seriously impact bed partners as well. Often, bed partners are the first to notice the RBD symptoms, as they can be violent and dangerous for the bed partner. The person with RBD may be unaware of the violence occurring during sleep, and may feel embarrassed when the bed partner explains the situation.

If you or your loved one is experiencing RBD, discuss with your doctor. There are possible medications that can help as well as adaptations and modifications to beds and bedrooms to enhance the safety for the person with Parkinsons as well as the partner.

What Happens During Rem Sleep

During REM sleep, your eyes move rapidly behind your closed eyes, your heart rate speeds up, and your breathing becomes irregular. In contrast to other stages of sleep, in which your brain waves slow down, your brain is highly active during REM sleep, and your brain waves become more variable.

During REM sleep, much of your body operates similarly to how it does when youre awake, except your eyes are closed and you experience a temporary loss of muscle tone. Researchers have hypothesized that this is a protective measure, meant to stop you from acting out your dreams and injuring yourself. However, now that scientists know we can experience dreams during non-REM sleep stages when our bodies are not paralyzed, this hypothesis is losing steam.

Various land-based species experience REM sleep, including humans and other mammals, reptiles like the Australian bearded dragon, and most birds. Although, REM sleep can look different depending on the species. For example, owls dont experience actual rapid eye movements during REM sleep since they cant move their eyes in their skulls. And, some birds only lose muscle tone in certain areas, like the neck, during REM sleep, so their head can rest while they keep standing on one foot.

Insights From Lesion Studies

To our knowledge, there are five cases of RBD associated with lesions in the brainstem. Kimura et al. reported on a 75-year-old woman who had PSG-verified RBD associated with a presumably ischaemic lesion in the left upper pons . A 25-year-old patient with relapsingâremitting multiple sclerosis had several hyperintensities in cerebral and pontine white matter . We also recently evaluated a 51-year-old female patient with MS who developed RBD, verified by PSG, suddenly after experiencing an MS exacerbation which was associated with a new demyelinating lesion in the dorsal pontine tegmentum . A 32-year-old patient who underwent a second surgical procedure for a tegmental ponto-mesencephalic cavernoma developed RBD . Additionally, a 59-year-old male with a 6-year history of essentially nightly RBD was found to have a brainstem neurinoma, and dream encactment behaviour disappeared after resection of the tumor . Based on the imaging findings in these reports, these cases indicate that lesions within or near the mesencephalic and pontine tegmentum can be associated with human RBD. Nevertheless, the specific nuclei, projections and neurochemical systems involved in human RBD pathophysiology are not adequately characterized. Clearly, neuroimaging of patients with acute onset RBD may further enhance our understanding of the neuroanatomic systems involved in RBD.

What Are The Other Sleep Disorders Similar To Rbd

REM Sleep Behaviour Disorder

Other sleep disorders similar to RBD include night terrors, narcolepsy, sleepwalking, and sleep-related epilepsy.

Night terrors Night terrors are most often seen in children, with symptoms including loud screams, thrashing of the limbs, and inconsolable terror during an episode. Night terrors can occur in adults and typically occur in deep sleep when one is difficult to wake up and may be combined with emotional reactions such as sweating, screaming, and even thrashing around in an attempt to flee.

  • Narcolepsy Narcolepsy is a disorder caused by disrupted REM sleep, leading to excessive daytime sleepiness or sudden bouts of sleep even when at rest.
  • Sleepwalking Sleepwalking is a disorder resulting from an activated brain state during non-REM sleep that occurs in deep, slow-wave sleep. This can cause a person to rise from slumber and display complex motor activity such as walking around while they are fast asleep.
  • Sleep-related epilepsy Sleep-related epilepsy is a disorder associated with seizures due to temporary electrical overactivity in the brain during sleep, leading to sensory or motor phenomena.

Possible Signs Of Rbd

  • You experience dream enactment behaviors.
  • Your loved one appears to be acting out their dreams.
  • You or a loved one awakens to find that injuries or damage have been sustained during sleep.

In any of these cases, please consult your physician. The good news? RBD may be treated successfully with clonazepam and melatonin.

You may also wish to safety-proof your sleeping place by padding corners of furniture, installing a bed rail, and putting dangerous items out of easy reach.

Take heart, however not everyone who experiences RBD goes on to develop PD.

What Are The Risk Factors For Rem Sleep Behavior Disorder

REM sleep behavior disorder primarily affects men over 60 years of age, with about 80% of cases being diagnosed with Parkinson’s disease however, the following factors may also increase the risk of developing the disorder.

  • Gender: Males are more likely to develop RBD than females at a risk ratio of 9 to 1.
  • Age: REM Sleep Behavior Disorder is most often diagnosed after the age of 50.
  • Family History: Having a family history of narcolepsy, Parkinson’s disease or other neurological disorders may indicate an increased risk for RBD.

Treating Rem Sleep Behavior Disorder And Co

NeuroLearn: REM Sleep Behavior Disorder: There Will Be Plaque – American Academy of Neurology

Frequently, RBD co-occurs with drug and alcohol addictions and other mental health conditions, such as depression and anxiety. Since these conditions can aggravate RBD, they need to be treated at the same time, which is a treatment approach known as dual-diagnosis care.

The treatment for these conditions may vary, and can include medications and psychotherapy. However, since certain medications, such as some classes of antidepressants, can make RBD symptoms and ultimately depressive symptoms worse, care must be taken to treat these other disorders in ways that do not worsen RBD.

Substance abuse can often lead to sleep disorders such as RBD. If you or a loved one are struggling with alcohol or drug dependence and poor sleep, specialized help is available. Contact The Recovery Village today to learn about how our co-occurring disorders treatment can help you.

Rbd Prognosis And Communicating The Risks

The prognosis for RBD depends largely upon the subtype. Patients diagnosed with RBD secondary to medication have the most promising prognosis of RBD resolution once the causative medication is withdrawn. However, it has been shown that RBD may persist following cessation of SSRIs , and it is therefore possible that in some cases the medication simply unmasked an already underlying pathology, triggering early clinical presentation . For RBD secondary to defined lesion e.g., inflammatory plaques, the main symptoms of RBD can be controlled relatively reliably using a combination of pharmacological and behavioral treatments. As these patient’s present with chronic but stable neural tissue damage, their RBD symptoms are unlikely to change over time.

For patients with RBD presenting as part of a clinically-defined neurodegenerative condition, such as PD, MSA, or DLB, the management of their sleep disorder should form part of their holistic care. Generally, the presence of RBD marks a less-favorable disease phenotype. In PD, for example, the presence of concomitant RBD is associated with a greater non-motor burden and a more adverse prognosis . There have been no studies of whether the symptomatic treatment of RBD impacts long-term outcomes in these patients.

Current Research: Rbd And The

The tests described in this section are used solely in experimental settings and therefore clinicians are not able to use them in the clinical RBD diagnostic or prognostic process. The majority of RBD research focuses upon the relationship between RBD and subsequent -synucleinopathy development. In particular, the search for biomarkers which identify underlying -synuclein pathology and predict RBD phenoconversion is perhaps the most relevant for clinical practice. As discussed previously there are no genetic markers with predictive power for RBD phenoconversion, and while rating scales may identify individuals with a high risk of phenoconversion, they do not have a binary outcome measure- a feature which is essential in prognostic testing.

Biomarkers for RBD conversion are essentially testing whether the RBD features of an individual are due to underlying -synuclein pathology or not. This can be done by testing for misfolded, pathological -synuclein in peripheral tissues and fluid samples. Dermal nerve fibers , cerebrospinal fluid , submandibular glands , colonic submucosal nerve fibers , salivary glands , and parotid glands have all been found to contain pathological -synuclein proteins in idiopathic RBD patient populations and confirmatory PD populations. Such investigations are in their infancy but show promise as a basis for relatively low-cost clinical diagnostic biopsy tests for alpha-synucleinopathy in RBD patients.

Causes Of Rem Sleep Behavior Disorder

REM sleep is a very active stage of sleep. Its known by sleep doctors as paradoxical sleep, because although it looks like people are fast asleep, their brain activity is almost indistinguishable from waking life.

REM is the stage of sleep where we experience dreams. To prevent us acting out our dreams, the body intentionally paralyses the body during REM sleep. People with REM sleep behavior disorder lack this protective paralysis, and so are free to act out their dreams.

REM sleep behavior disorder is commonly linked to the development of neurodegenerative diseases such as Parkinsons, dementia and narcolepsy. These diseases sometimes develop before REM sleep behavior disorder, alongside, or after many years of first having REM sleep behavior disorder. However while having REM sleep behavior disorder increases your chances of having a neurodegenerative disease, sometimes they do not develop at all.

REM sleep behavior disorder has also been linked to the following:

  • Certain types of medication Often certain antidepressants
  • Drug or alcohol abuse
  • Drug or alcohol withdrawal
  • Stroke

Generally REM sleep behavior disorder caused by the above often goes away after a short spell, but is has been reported in a few cases for it to develop further.
