Does postural rigidity decrease during REM sleep without Atonia in Parkinson disease?

open access: yes, 2016
Study Objectives: Rigidity is a muscle hypertonia typical of Parkinson disease (PD), whereas rapid eye movement (REM) sleep behavior disorder (RBD) is characterized by abnormally increased muscle tone during REM sleep (REM sleep without atonia) and ...

Digital Handwriting Reveals Motor Impairment, Dopaminergic Response, and Progression in Parkinson's Disease

open access: yesMovement Disorders Clinical Practice, EarlyView.
Abstract Background Digital handwriting distinguishes PD patients from healthy controls but is rarely assessed quantitatively. Objectives To evaluate digital handwriting as an objective tool to assess motor impairment, dopaminergic response, and progression in PD.

Melanopsin‐Mediated Post‐Illumination Pupillary Response in Idiopathic Rapid Eye Movement (REM) Sleep Behavior Disorder and Parkinson's Disease

open access: yesMovement Disorders, EarlyView.
Abstract Aims To conduct a case–control study to investigate melanopsin‐mediated post‐illumination pupillary response (PIPR) in patients with Parkinson's disease (PD), video‐polysomnography‐confirmed isolated/idiopathic rapid eye movement (REM) sleep behavior disorder (iRBD), and age‐matched healthy controls (HC). Methods PIPR was measured at 6 s after

Apathy in Lewy Body Disorders: A Position Paper

open access: yesMovement Disorders, EarlyView.
Abstract Apathy is one of the most prevalent and disabling non‐motor symptoms in Parkinson's disease (PD) and dementia with Lewy bodies (DLB), collectively referred to as Lewy body disorders (LBDs). It is associated with reduced quality of life, accelerated cognitive decline, increased caregiver burden, and poorer functional outcomes, yet remains ...

Decoding Sleep Architecture from Ambulatory Basal Ganglia Signals in Parkinson's Disease

open access: yesMovement Disorders, EarlyView.
Abstract Background Sleep architecture and circadian rhythms are frequently disrupted in Parkinson's disease (PD). BrainSense‐enabled neurostimulators combined with wearable technology enable chronic assessment of nocturnal brain activity, with potential for future diagnostics and personalized treatments. Objectives To neurophysiologically characterize

The Effect of LRRK2 and GBA1 Mutations on Survival in Early‐ and Late‐Onset Parkinson's Disease

open access: yesMovement Disorders, EarlyView.
Abstract Background Mutations in the glucocerebrosidase 1 (GBA1) and leucine‐rich repeat kinase 2 (LRRK2) genes are associated with Parkinson's disease (PD) phenotype. Objective To asses the contribution of genetic status to long‐term survival of patients with PD.

Dopamine‐Deficiency‐Related Reorganization of the Somatomotor Network in Prodromal and Early Parkinson's Disease

open access: yesMovement Disorders, EarlyView.
Abstract Introduction Network attack tolerance (NAT) measures the brain's ability to sustain information flow despite the loss of critical brain regions. In Parkinson's disease (PD), NAT has been linked to cognitive and motor function. However, it remains unclear how dopaminergic degeneration shapes NAT, and whether it relates to motor symptom ...
