Motor–Behavioral Phenotypes in the RBD-PD Continuum: Neurophysiological Mechanisms and Rehabilitative Implications

Applied Sciences
REM sleep behavior disorder (RBD) represents a prodromal manifestation of Parkinson’s disease (PD), reflecting the breakdown of inhibitory networks extending from the brainstem to the cortex.

A crime case which took place during REM sleep disorder and the evaluation of the case by the forensic psychiatry [PDF]

Düşünen Adam Psikiyatri ve Nörolojik Bilimler Dergisi, 2011
Sleep-related behavior disorders are the disturbing behaviors which occur during sleep, targeting himself or others. Although the exact prevalence is still unknown, it is clear that they are more frequent in males than females and mostly appear to be a ...

Facilitatory/inhibitory intracortical imbalance in REM Sleep Behavior Disorder: early electrophysiological marker of neurodegeneration?

Sleep, 2019
STUDY OBJECTIVES Previous studies found an early impairment of the short-interval intracortical inhibition (SICI) and intracortical facilitation (ICF) to transcranial magnetic stimulation (TMS) in Parkinson's disease. However, very little is known on the

Differential impact on isolated REM sleep without atonia by varying antidepressant therapies

Journal of Affective Disorders Reports, 2020
Background: REM sleep without atonia (RSWA) is characterized by increased phasic or tonic muscle activity in electromyography channels during polysomnography and usually causes REM sleep behavior disorder, but RSWA also exists within healthy populations ...

Cortical thinning in patients with REM sleep behavior disorder is associated with clinical progression

npj Parkinson's Disease, 2019
The aim of this study is to determine whether structural MRI measures are associated with clinical impairment and progression to a Lewy body disease in patients with idiopathic REM sleep behavior disorder (iRBD).

Polysomnographic Features of Sleep Disturbances and REM Sleep Behavior Disorder in the Unilateral 6-OHDA Lesioned Hemiparkinsonian Rat

Parkinson's Disease, 2014
Sleep pattern disruption, specifically REM sleep behavior disorder (RBD), is a major nonmotor cause of disability in PD. Understanding the pathophysiology of these sleep pattern disturbances is critical to find effective treatments.

Risk Factors for Neurodegeneration in Idiopathic REM sleep Behavior Disorder: A Multicenter Study

Annals of Neurology, 2015
To assess whether risk factors for Parkinson disease and dementia with Lewy bodies increase rate of defined neurodegenerative disease in idiopathic rapid eye movement (REM) sleep behavior disorder (RBD).

Simultaneous tonic and phasic REM sleep without atonia best predicts early phenoconversion to neurodegenerative disease in idiopathic REM sleep behavior disorder.

Sleep, 2019
STUDY OBJECTIVES Rapid eye movement (REM) sleep without atonia (RWA) is the main polysomnographic feature of idiopathic REM sleep behavior disorder (iRBD) and is considered to be a promising biomarker predicting conversion to manifested synucleinopathy ...

Beyond RBD: covert REM sleep abnormalities in Parkinson’s disease

npj Parkinson's Disease
REM sleep behavior disorder (RBD), involving REM sleep without atonia (RSWA), is a prodromal marker of Parkinson’s disease (PD). We investigated whether RBD may represent the “tip of the iceberg” of pathology driving wider REM sleep disruptions.
