Dopamine modulates learning conflicting action-valence associations in Parkinson’s disease
Objective: To investigate the effect of dopaminergic medication in Parkinson's disease (PD) on learning to act and learning to withhold action based on rewarding versus…Plasma ceramides and glucosylceramides predict cognitive decline among cognitively normal Parkinson’s disease patients
Objective: To determine whether plasma ceramides, glucosylceramides, and their ratios predict cognitive decline among cognitively normal Parkinson's disease (PD) patients. Background: There are no biomarkers…Self-reported cognitive complaints and neuropsychological performance in idiopathic REM sleep behavior disorder
Objective: The aim of this study was to investigate self-reported cognitive complaints in idiopathic REM sleep behavior disorder (iRBD) in link with the presence of…The cognitive profile of idiopathic REM sleep behavior disorder
Objective: The aim of this study was to examine the cognitive profile in a large cohort of patients with idiopathic REM sleep behavior disorder (iRBD).…Profile of depressive symptoms in Parkinson’s disease patients and a population-based elderly cohort

Objective: To evaluate correlations of depression and anxiety levels with motor symptoms, non-motor symptoms and pharmacological factors in Parkinson's disease (PD). Background: Depression and anxiety…Coin rotation as strongest predictor of buttoning in Parkinson’s: A multicenter study demonstrating the everyday impact of limb-kinetic apraxia
Objective: Applying a three site multi-center approach, we aimed to identify the significant predictors of buttoning and unbuttoning in PD. We hypothesized that coin rotation…Blinded video assessment of subtle Parkinsonian signs in PREDICT-PD participants
Objective: To determine whether risk estimates calculated in PREDICT-PD are associated with objective motor features on clinical examination. Background: PREDICT-PD aims to identify a group…Disability is an independent predictor of falls and recurrent falls in people with Parkinson’s disease without a history of falls: A one-year prospective study
Objective: To determine predictors of all falls and recurrent falls in people with Parkinson's disease (PD) who had not fallen in the past year; and…Independent validation of the quality of life in essential tremor questionnaire (QUEST)
