REM Sleep Behavior Disorder
Overview. 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.
Cluster Number:
Wiki Number: PW185
Diagnosis: Rapid Eye-Movement Sleep Behavior Disorder
US Patients: 5-13% of those aged 60-99;Of those suffering, 33-65% have injured themselves or a bed-partner.
World Patients: Most people with this diagnosis will develop synucleinopathy (proteins clumping up) leading to Parkinson’s/Lewy-Body Dementia.
Sex Ratio: M+;W
Age Onset: 50’s & 60’s
Brain Area: neurodegenerative disorder; pontomedullary brainstem and/or caudal brainstem have lesions and may lead to synucleinopathy
Symptoms: while still sleeping, people act out their dreams; may injure their bed-partner through punching, flailing, running, etc.;
Progression: This condition has also been diagnosed in animals, spefically dogs.
Causes: Parkinson’s, Lewy Body Dementia and similar conditions often do this; muscle weakness or paralysis may be a factor
Medications: melotonin and clonazepam; some other medications may worsen this.
Therapies: placing cushions around the bed or moving the mattress to the floor; keeping a normal sleep schedule, avoding alcohol, etc

- Being Prodromal: Current Criteria in the Context of Isolated REM Sleep Behavior Disorderby Anja Ophey on February 22, 2025
CONCLUSIONS: The observed overlap leads to challenges in patient counseling and risk disclosure. Better discrimination will facilitate research in early α-synucleinopathy phases.
- Cholinergic degeneration and early cognitive signs in prodromal Lewy body dementiaby Kyung Ah Woo on February 22, 2025
CONCLUSION: cBF degeneration evolves from the prodromal iRBD stage of LBDs and predicts dementia, highlighting a window for cholinergic-targeted intervention.
- Cross-evaluation of wearable data for use in Parkinson's disease research: a free-living observational study on Empatica E4, Fitbit Sense, and Ouraby Haakon Reithe on February 21, 2025
CONCLUSIONS: In this study we identified a set of characteristics necessary for PD research: ease of handling, cleaning, data retrieval, access to raw data, score calculation transparency, long battery life, sufficient storage, higher sampling frequencies, software and hardware reliability, transparency. The three analyzed devices are not interchangeable and, based on data features, none were deemed optimal for PD research, but they all have the potential to provide suitable specifications in...
- Non-motor symptoms in prodromal Parkinson's disease are linked to reduced quality of lifeby Sinah Röttgen on February 20, 2025
Isolated rapid eye movement (REM) sleep behavior disorder (iRBD) highlights an early α-synucleinopathy. This study compared health-related quality of life (hrQoL) in 62 individuals with iRBD with 19 healthy controls (HC) and 29 individuals with Parkinson's disease (PD) and identified factors linked to poorer hrQoL. HrQoL was significantly lower in individuals with iRBD (83.33 ± 16.96) compared to HC (92.29 ± 5.49, p = 0.027). Poorer hrQoL in individuals with iRBD was linked to severity of...
