Objective We aim to investigate the disturbance of neural network associated with the
different clinical stages of Parkinson's disease (PD). Method We recruited 80 patients at …

Objective Parkinson's disease (PD) affects the structural integrity and neurophysiological
signaling of the cortex. These alterations are related to the motor and cognitive symptoms of …

Parkinson's disease (PD) and the parkinsonian variant of multiple system atrophy (MSAp)
are neurodegenerative disorders that can be difficult to differentiate clinically. This study …

Dopamine depletion in the putamen is associated with altered motor network functional
connectivity in people with Parkinson's disease (PD), but the functional significance of these …

Background MRI brain changes in Parkinson's disease (PD) are controversial. Objectives
We aimed to describe structural and functional changes in PD. Methods Sixty-six patients …

Previous computational model‐based approaches for understanding the dynamic changes
related to Parkinson's disease made particular assumptions about Parkinson's disease …

Background and purpose Cognitive impairment is a common non-motor complication of
Parkinson's disease (PD). To investigate cognitive-related changes of gray matter (GM) …

Parkinson's disease (PD) is a neurodegenerative disorder primarily affecting the aging
population. The neurophysiological mechanisms underlying parkinsonian symptoms remain …

Previous neuroimaging studies have found hyperactivation in the cerebellum and motor
cortex and hypoactivation in the basal ganglia in patients with Parkinson's disease (PD) but …

Background Whereas the motor dysfunction in Parkinson's disease (PD) has been related to
deficits in basal ganglia (BG) structures, neural correlates of cognitive changes remain to be …
