Background Cognitive impairment is a common non-motor symptom in Parkinson's disease.
So far, the underlying pathophysiology remains unclear. Several alterations in functional …

Objective: To evaluate fMRI whole-brain resting-state functional connectivity changes in
relation to cognitive decline in Parkinson disease (PD) over a 3-year period. Methods …

Objective: Using resting-state (RS) fMRI, we investigated the functional integrity of the
default-mode network (DMN) in cognitively unimpaired patients with Parkinson disease …

Parkinson's disease (PD) is a common progressive neurodegenerative disorder. Studies
using resting-state functional magnetic resonance imaging (fMRI) to investigate underlying …

Cognitive impairment is common in PD, even in early stages. The construct of mild cognitive
impairment has been used to identify clinically evident cognitive impairment without …

Cognitive impairment is a common non-motor feature of Parkinson's disease (PD).
Understanding the neural mechanisms of this deficit is crucial for the development of …

Biomarkers in whichever modality are tremendously important in diagnosing of disease,
tracking disease progression and clinical trials. This applies in particular for disorders with a …

Since anatomic MRI is presently not able to directly discern neuronal loss in Parkinson's
Disease (PD), studying the associated functional connectivity (FC) changes seems a …

ABSTRACT Background Functional MRI (fMRI) has been widely used to study abnormal
patterns of functional connectivity at rest in patients with movement disorders such as …

Involvement of the default mode network (DMN) in cognitive symptoms of Parkinson's
disease (PD) has been reported by resting‐state functional MRI (rsfMRI) studies. However …
