REM sleep behavior disorder can be the first indication of development of a neurodegenerative disease, such as Parkinson's disease, multiple system atrophy or dementia with Lewy bodies.

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.

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. During REM, dreams may be much more vivid. This is due to the fact that the brain is more active during this stage. REM sleep is important and is associated with many aspects of health and brain function. Therefore it is important to get enough REM sleep to be better able to function during the day. The image below shows the stages of sleep we move through in a typical night. Parasomnia is a word used to describe unusual behaviours that occur during sleep. There are many different forms, with sleepwalking being the classic example. They are common during childhood but occur more rarely in adults.

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.
