• #3 REM sleep behavior disorder: Symptoms, causes, and treatment

  https://www.medicalnewstoday.com/articles/247730

  REM sleep behavior disorder involves unusual actions or behaviors during the rapid eye movement sleep phase. […] During the REM phase of sleep, the muscles in the body usually enter a state of temporary paralysis. In a person with RBD, this paralysis is incomplete or even completely absent, so the person acts out their dreams, sometimes in dramatic or violent ways. […] The lack of temporary muscle paralysis causes sleepers with RBD to become physically agitated, actively move their limbs, leave the bed, and engage in other actions linked to being awake. […] In some cases, people with RBD might injure themselves or whomever else shares their bed. […] A person with RBD may demonstrate the following behaviors while asleep: talking, shouting, screaming, lashing out physically, punching and kicking, cursing, a clear ability to recall dreams on waking, sleepwalking.

  Rapid eye movement (REM) sleep behavior disorder is a parasomnia in which affected individuals act out their dreams while in the REM stage of sleep. Unfortunately, this can involve violence and can lead to the injury of self or others without conscious awareness. Patients with this disorder can typically recall the content of the dream upon awakening. Many patients with REM sleep behavior disorder will eventually develop neurodegenerative diseases like Parkinson’s disease, Lewy body dementia, or multiple system atrophy. […] Most patients with REM behavior disorder will eventually manifest neurodegenerative diseases like parkinsonism, dementia with Lewy body, or multisystem atrophy.

  https://www.psychologytoday.com/us/conditions/rapid-eye-movement-sleep-behavior-disorder

  People with rapid eye movement (REM) sleep behavior disorder react physically to what they are dreaming. […] During REM sleep, people typically experience vivid dream imagery but also a loss of muscle tone similar to paralysis, known as atonia. Because of this, most people are not able to physically respond to their dreams. People with REM sleep behavior disorder, however, can enter REM sleep without atonia, enabling them to act on their dream imagery. […] Episodes of REM sleep behavior disorder usually start more than 90 minutes after a person has fallen asleep, when they are in a REM state. Their screaming, moaning, or singing is typically loud, emotional, and may include profanity, and their physical behaviors can include running, punching, hitting, jumping out of bed, and kicking. […] For a diagnosis of REM sleep behavior disorder to be made, this behavior must cause significant distress or impairment in some important area of daily life, including injury to oneself or to ones bed partner during sleep.

  Rapid eye movement (REM) sleep behavior disorder involves episodes of arousal during sleep associated with speaking and/or movement. The persons actions are often responses to events in the dream, such as being attacked or trying to escape a threatening situation. Speech is often loud, emotion-filled, and profane. These behaviors arise during REM sleep and usually occur more than 90 minutes after falling asleep. Upon awakening, the person is immediately alert and can often recall the dream. […] REM sleep behavior disorders may cause significant distress and problems with functioning, including injury to the individual and their bed partner (such as falling, jumping, or flying out of bed; running, hitting, or kicking). Embarrassment about the episodes can cause problems in social relationships and can lead to social isolation or work-related problems.

  REM sleep behavior disorder (RBD) is a rare parasomnia in which you physically act out your dreams while you’re in the rapid eye movement (REM) stage of sleep, according to the Cleveland Clinic. The main symptom of REM sleep behavior disorder is physically acting out your dreams, because your body isn’t immobilized like it should be during REM sleep. It may start suddenly or come on gradually but typically gets worse over time. You may have episodes every once in a while or several times in a night. Other symptoms, according to the Mayo Clinic, include: Making noises like talking, laughing, shouting, or yelling for help; Being easy to awaken during an episode, coherent afterward, and able to recall the dream; Unpleasant dream content like arguments, accidents, or attacks. Typically, these are violent dreams, says Dr. Cline. Episodes often happen in the second half of the night into the morning, when you experience longer phases of REM sleep. […] One study found that 30 percent of people with RBD developed Parkinson’s disease or dementia within three years of sleep symptoms and 66 percent did within eight years.

  People who have RBD aren’t aware of their behaviors during sleep. Many people only find out they have RBD when their bed partner or roommate tells them about their behavior or when they wake up with an injury. […] The prognosis (outlook) of REM sleep behavior disorder depends on a few factors, including: If there’s an underlying cause, such as narcolepsy (secondary RBD) or use of an antidepressant (drug-induced RBD), or if it developed spontaneously (isolated RBD). How severe your symptoms are and if your symptoms lead to injury. If it’s treated or untreated. If you have RBD and a neurodegenerative condition. […] RBD can cause serious injury to you and/or your bed partner, so it’s important to seek treatment. […] Due to the potentially violent nature of their movements, people with REM sleep behavior disorder can put themselves and their bed partner at risk of injury. It can also cause frequent sleep disruptions, which can affect your overall quality of sleep. […] Injuries can include: Bruises. Cuts. Sprains. Broken bones. Head injury and subdural hematomas. […] Up to 90% of partners of people with RBD have sleep issues. Over 60% have experienced a physical injury.

  Most people with RBD are unaware of it, but some present to their GP reporting frequent vivid dreams, unexplained injuries (related to thrashing into a wall or furniture when dreaming), or falling out of bed. […] In the absence of an overt NDD, diagnosis of iRBD can lead to treatment (associated with improved quality of life), as well as opportunities for risk modification and clinical trial recruitment that hold potential to slow or even stop progression to NDD. […] While there remains uncertainty around iRBD and its association with different types of NDD, it is clear that iRBD is a prodrome of neurodegeneration. This means there is an opportunity for dementia risk reduction through managing potentially modifiable dementia risk factors. GPs therefore play a vital role in recognising potential iRBD and applying preventive medicine approaches with the aim of trying to alter iRBD trajectories.

  REM (rapid eye movement) sleep behaviour disorder (RBD) is characterised by vivid dreams and dream enactment behaviour such as kicking, shouting, and punching. It can result in injuries to the person with RBD and their bed partner, and is associated with reduced quality of life and severely disrupted sleep. […] RBD affects approximately 50% of people with Parkinsons disease (PD), 80% of people with dementia with Lewy bodies (DLB), and almost 100% of people with multiple system atrophy (MSA). RBD is also an early sign of neurodegenerative disease and can occur in otherwise healthy individuals when it is known as idiopathic or isolated RBD (iRBD). This isolated form is associated with an 80-90% risk of progression to an NDD, such as PD or DLB, within 10 years of first diagnosis. […] Identifying iRBD provides a rare opportunity to modify future risk of neurodegeneration and there are anticipated opportunities for patients with iRBD to enrol in neuroprotective drug trials to prevent progression to an overt NDD.

• #35 REM Sleep Behavior Disorder: Background, Etiology, Epidemiology

  https://emedicine.medscape.com/article/1188651-overview

  The prognosis of rapid eye movement sleep behavior disorder (RBD) depends on its etiology. In idiopathic cases, the symptoms are controlled with medications. In secondary cases, the prognosis depends on the underlying primary disease. For example, patients with Parkinson disease and RBD have poorer cognitive performance and a greater risk of dementia compared to patients with Parkinson disease but without RBD. […] No deaths have been reported in idiopathic cases of RBD; however, patients and bed partners may experience serious injury.

  REM sleep behavior disorder (RBD) is a parasomnia characterized by dream enactment in the setting of loss of physiological muscle atonia during REM sleep, with vocal and/or motor behaviors that may lead to injuries during sleep period. […] The isolated form of REM sleep behavior disorder (RBD), a parasomnia with dream enactment behaviors and excessive muscle activity during REM sleep, is an early stage synucleinopathy. […] A high proportion of individuals affected by iRBD eventually develop synuclein-specific neurodegenerative disorders (i.e., synucleinopathies) such as PD, DLB or MSA. […] The largest international study to date that examined 1280 patients with RBD revealed a phenoconversion rate of 6.3% per year; 73% of this study cohort developed a synucleinopathy within a 12-year follow up period.

  Rapid eye movement (REM) sleep behavior disorder (RBD) is a parasomnia characterized by dream-enactment behaviors that emerge during a loss of REM sleep atonia. RBD dream enactment ranges in severity from benign hand gestures to violent thrashing, punching, and kicking. Patients typically present to medical attention with a concern related to injurious or potentially injurious actions to themselves and/or their bed partner. […] In spontaneously occurring cases, RBD is a prodromal syndrome of alpha-synuclein neurodegeneration. Thus, the vast majority of RBD patients will eventually demonstrate signs and symptoms of Parkinson disease (PD) or a related disorder (eg, multiple system atrophy or dementia with Lewy bodies), often after a prolonged interval. Prior to the emergence of a parkinsonian syndrome, patients may have subtle sensory, motor, and cognitive deficits, including anosmia and constipation, consistent with an impending neurologic disorder.

  During sleep, patients with RBD act out violent dreams. […] The frequency of behaviors varies considerably from night to night. […] Due to the violent nature of these behaviors, patients may injure themselves or their loved ones, leading to abrasions and fractures. […] However, patients with iRBD may have mild motor and non-motor symptoms. […] In the motor domain, signs of parkinsonism may include minimal cogwheel rigidity when the examiner moves the wrist, mild hypokinesia or bradykinesia, loss of arm swing when walking, and subtly decreased face and vocal expression. […] The olfactory and autonomic signs often appear well before motor and cognitive signs in the progression from iRBD to overt parkinsonism/dementia. […] People with PD who also have RBD most commonly have the rigid-akinetic form of parkinsonism, more non-motor signs and hallucinations, and progress more quickly to PD dementia, motor disability, and falls, suggesting a more severe form of PD.

  As the first indication of an underlying neurodegenerative disorder or synucleinopathy, symptoms of RBD may begin years or decades before the onset of another condition. Abnormal sleep behaviors may begin decades before any other symptoms, often as the first clinical indication of another condition. […] Other symptoms found in patients with RBD are reduced motor abilities, posture and gait changes, mild cognitive impairment, alterations in the sense of smell, impairments in color vision, autonomic dysfunction (orthostatic hypotension, constipation, urinary problems and sexual dysfunction), and depression. […] Almost 92% of patients with idiopathic RBD will go on to develop a neurodegenerative disorder. The disorders most strongly associated with RBD are the synucleinopathies, particularly Parkinson’s disease, dementia with Lewy bodies, and to a lesser extent, multiple system atrophy. Most people with RBD will convert to a synucleinopathy—usually Parkinson’s disease or dementia with Lewy bodies—within 4 to 9 years from diagnosis of RBD, and 11 to 16 years from onset of symptoms.

  Its often easier for a person to know that they have REM sleep behavior disorder when they share the bed with a sleeping partner. Someone who is in the room with them and awake when they are experiencing symptoms may observe them kicking, punching, reaching out or moaning. […] A person with REM sleep behavior disorder (RBD) may wake their partner by grabbing them, shouting their name or even talking to them. It may take some time for a person who sleeps next to someone with RBD to realize that their speaking sleeping partner is not awake. The bizarre or unrealistic content of speech may ultimately signal that the person with RBD is speaking in their sleep. […] Detecting REM sleep behavior disorder symptoms is a bit more difficult when someone does not share the bed with a sleeping partner, but it is possible. Signs that someone experienced disordered movement during REM sleep include: Finding items knocked off or moved from nearby tables or other surfaces, Seeing sheets, pillows or other bedding items on the floor or far from the bed, Discovering unexplained bruises, scratches or other physical marks on their body.

  There is a strong association of RBD with many neurodegenerative disorders. RBD can be a precursor to more serious conditions involving alpha-synuclein neuropathies such as parkinsonism, multiple system atrophy, or dementia with Lewy body where prevalence can be as high as 76% to 81% of affected individuals. […] In a case series, about half of the patients with RBD converted to a neurologic disorder within 12 years. […] RBD can be a disturbing disorder for both patients and their bed partners. Both are prone to injuries due to violent behavior. Most patients with spontaneous RBD can eventually develop a neurodegenerative disorder. The rate of conversion is about 50% every 10 years. […] Patients should be informed that they are at risk of developing neurodegenerative disorders.

  The decrease of severity of the RBD-phenotype already after 3 weeks of ADLL therapy may be due to a functional improvement of neurons in circuits controlling REM sleep atonia and dream content. […] The objective DAT-SPECT and FDG-PET data suggest that ADLL treatment may modify the progression of iRBD and its conversion to the PD phenotype. […] Thus, these results support further explorations whether ADLL may have disease-modifying properties in prodromal PD.
