Cognitive impairment is one of the most salient non-motor symptoms of Parkinson disease
(PD) that poses a significant burden on the patients and carers as well as being a risk factor …

Cognitive impairment (CI) is a characteristic non-motor feature of Parkinson disease (PD)
that poses a severe burden on the patients and caregivers, yet relatively little is known about …

Background Although dysfunction of large-scale brain networks has been frequently
demonstrated in patients with α-Synucleinopathy (α-Syn, ie, Parkinson's disease, dementia …

Pathological process in Parkinson's disease (PD) is accompanied with functional and
metabolic alterations. The time-varying properties of functional coherence and their coupling …

We aimed to study the effect of Parkinson's disease (PD) and motor-cognitive load on the
interplay between activation level and spatial complexity. To that end, 68 PD patients and 30 …

Survivors of pediatric brain tumors experience significant cognitive deficits from their
diagnosis and treatment. The exact mechanisms of cognitive injury are poorly understood …

Objective: Parkinson's disease (PD) may affect not only motor functions, but also cognitive
processes such as attention. While past research has examined PD impact on spatial …

Aging is widely acknowledged as the primary risk factor for brain degeneration, with
Parkinson's disease (PD) tending to follow accelerated aging trajectories. We aim to …

Flexibility is a hallmark of cognitive control and can be driven externally and internally,
corresponding to reactive and spontaneous flexibility. However, the convergence and …

Recent studies in Parkinson's disease (PD) patients reported disruptions in dynamic
functional connectivity (dFC, ie, a characterization of spontaneous fluctuations in functional …
