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

- Lysosomal and synaptic dysfunction markers in longitudinal cerebrospinal fluid of de novo Parkinson's diseaseby Michael Bartl on May 17, 2024
Lysosomal and synaptic dysfunctions are hallmarks in neurodegeneration and potentially relevant as biomarkers, but data on early Parkinson's disease (PD) is lacking. We performed targeted mass spectrometry with an established protein panel, assessing autophagy and synaptic function in cerebrospinal fluid (CSF) of drug-naïve de novo PD, and sex-/age-matched healthy controls (HC) cross-sectionally (88 PD, 46 HC) and longitudinally (104 PD, 58 HC) over 10 years. Multiple markers of autophagy,...
- Static and dynamic brain morphological changes in isolated REM sleep behavior disorder compared to normal agingby Gilsoon Park on May 16, 2024
CONCLUSION: Patients with iRBD show brain atrophy in the regions that are overlapped with the areas that have been documented to be affected in early stages of Parkinson's disease. Such atrophy in iRBD may not be progressive but may be slower than that in normal aging. Cognitive impairment in iRBD is not progressive.
- Predictive Modeling Using a Composite Index of Sleep and Cognition in the Alzheimer's Continuum: A Decade-Long Historical Cohort Studyby Xianfeng Yu on May 15, 2024
CONCLUSIONS: In conclusion, the sleep-cognition nomogram we developed could successfully predict the risk of converting to CI in elderly participants and could potentially guide the design of interventions for rehabilitation and/or cognitive enhancement to improve the living quality for healthy older adults, detect at-risk individuals, and even slow down the progression of AD.
- Molecular beacon-based detection of circulating microRNA-containing extracellular vesicle as an α-synucleinopathy biomarkerby Zhenwei Yu on May 15, 2024
Early and precise diagnosis of α-synucleinopathies is challenging but critical. In this study, we developed a molecular beacon-based assay to evaluate microRNA-containing extracellular vesicles (EVs) in plasma. We recruited 1203 participants including healthy controls (HCs) and patients with isolated REM sleep behavior disorder (iRBD), α-synucleinopathies, or non-α-synucleinopathies from eight centers across China. Plasma miR-44438-containing EV levels were significantly increased in...
