Rapid eye movement sleep behavior disorder

Rapid eye movement REM sleep behavior disorder is a sleep disorder in which you physically act out vivid, often unpleasant dreams with vocal sounds and sudden, often violent arm and leg movements during REM sleep — sometimes called dream-enacting behavior.

Rapid eye movement sleep behavior disorder

Rapid eye movement sleep behavior disorder or REM behavior disorder RBD is a sleep disorder in which people act out their dreams. It involves abnormal behavior during the sleep phase with rapid eye movement REM sleep. The major feature of RBD is loss of muscle atonia i. The loss of motor inhibition leads to sleep behaviors ranging from simple limb twitches to more complex integrated movements that can be violent or result in injury to either the individual or their bedmates. RBD is a very strong predictor of progression to a synucleinopathy usually Parkinson's disease or dementia with Lewy bodies. RBD is a parasomnia. It is categorized as either idiopathic or symptomatic. RBD is characterized by the dreamer acting out their dreams, with complex behaviors. The actions in an episode can result in injuries to oneself or one's bedmate. Because violence in dreams is more likely to be recalled, this could be an artifact of recall bias or selection bias.

During this test, sensors monitor your heart, lung and brain activity, breathing patterns, arm and leg movements, vocalizations, and blood oxygen levels while you sleep.

In REM sleep behaviour disorder RBD , there is a loss of this muscle atonia where patients are able to act out their dreams, which can result in serious injury to the patient and their bed partner. This article focuses on the role of the general practitioner GP in the diagnosis and management of RBD. It is anticipated that early recognition of RBD will be critical in the future use of neuroprotective agents to help tackle conditions like PD and LBD. James was 54 years old when he was referred to a sleep disorder clinic because he broke his wrist diving out of bed while dreaming he was about to be hit by a train. The previous month he hit his wife while dreaming a tiger was attacking him.

Rapid eye movement behavior disorder RBD is parasomnia strongly linked to neurodegenerative diseases, and it can also be very disturbing and lead to injury requiring medical attention.

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. A careful history should distinguish RBD from related parasomnias such as sleepwalking. In-laboratory video polysomnography can exclude other sleep disorders, quantify REM atonia and capture dream-enactment behaviors, confirming the diagnosis. The main focus of treatment is to reduce behavioral events and prevent sleep-related injury; this can be achieved through changes in the sleeping environment and, if necessary, pharmacotherapy eg, melatonin, clonazepam.

Your doctor is likely to ask you a number of questions. Around half of people will experience this once, but frequent episodes can cause anxious feelings about going to sleep. Evaluation The diagnosis of rapid eye movement behavior disorder comprises two features: loss of normal atonia during REM sleep and dream enactment behavior. The International Classification of Sleep Disorders, 3 ed. The first period of REM normally lasts around 10 minutes, and as sleep continues there tends to be more REM in the second half of the night. Your evaluation may include: Physical and neurological exam. Recent evidence suggests that there may also be several specific environmental or personal risk factors for REM sleep behavior disorder, including occupational pesticide exposure, farming, smoking or a previous head injury. Admissions Requirements. Other second-line therapies [54] for RBD include dopaminergic agents such as L-DOPA and pramipexole [55] [56] , paroxetine, acetylcholinesterase inhibitors such as Donepezil and Rivastigmine [57] [58] [57] , Desipramine, Clozapine, Antiepileptic Drugs e.
