The effect of dopaminergic therapy on stimulus-response learning and decision-making in Parkinson’s disease using fMRI
Objective: Our aim was to examine the neural correlates of stimulus-response (SR) learning in patients with Parkinson's disease (PD) on and off dopaminergic (DA) therapy…Modulation of local field potentials during gait in the STN of patients with Parkinson’s disease
Objective: PD patients with implanted DBS electrodes allow for the investigation of basal ganglia activity during gait. Background: Whereas the overall spectral content of local…The feasibility of measuring fatigability in early-stage Parkinson’s disease using functional MRI
Objective: To investigate the effect of fatiguability on brain activation in people with Parkinson's (PwP) in comparison with healthy volunteers(HV). Background: Fatiguability, an objective decline…Alterations in muscle synergies in early stage Parkinson’s disease
Objective: Identify whether muscle synergies are altered in stage I Parkinson's disease (PD). Background: Muscle synergies have been proposed as a mechanism utilized by the…The patterns of olfactory function in Parksinson’s disease patients with mild cognitive impairment
Objective: To examine relationship between olfactory dysfunction and PD-MCI, and investigated the patterns of olfactory function in subtypes of PD-MCI patients using the Korean version…Levodopa impairs learning in healthy young adults: Implications for Parkinson’s disease
Objective: The objective was to investigate the effect of dopaminergic therapy on healthy young adults to test the dopamine overdose hypothesis. Background: Dopaminergic therapy improves…Association or causation? Orthostatic hypotension and cognitive impairment in α-synucleinopathies: A systematic review
Objective: To systematically review the literature for evidence of an association between orthostatic hypotension (OH) and cognitive impairment (CI) in α-synucleinopathies and to discuss possible…Circulatory levels of BDNF correlate with cognitive deficits in people with Parkinson’s disease
Objective: The aim of this study was to examine the relationship of serum BDNF levels with cognitive function. Background: Brain-derived neurotrophic factor (BDNF) is essential…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…
