Background: Functional imaging methods, such as resting-state functional magnetic
resonance imaging, reflect changes in neural connectivity and may help to assess the …

Cognitive deficits in Parkinson's disease are thought to be related to altered functional brain
connectivity. To date, cognitive-related changes in Parkinson's disease have never been …

Parkinson's disease (PD) is a neurodegenerative disorder affecting dopaminergic neurons
in the substantia nigra leading to dysfunctional cortico-striato-thalamic-cortical loops. In …

Aim: The aim of the present study is to investigate the relationship between both functional
connectivity and brain networks with cognitive decline, in patients with Parkinson's disease …

Abstract See Nieuwhof and Helmich (doi: 10.1093/brain/awx267) for a scientific commentary
on this article. Parkinson's disease is a neurodegenerative disorder characterized by …

Introduction The study aim was to identify longitudinal abnormalities of functional
connectivity and its relation with motor disability in early to moderately advanced stages of …

Abstract Background/Aims: The topological organization of brain functional networks is
impaired in Parkinson's disease (PD). However, the altered patterns of functional network …

Parkinson's disease (PD) is a neurodegenerative disorder characterized by topological
abnormalities in large-scale functional brain networks, which are commonly analyzed using …

Background: Cognitive impairment in Parkinson's disease (PD) is associated with altered
connectivity of the resting state networks (RSNs). Longitudinal studies in well cognitively …

Cognitive deficits are common in Parkinson's disease and we suspect that dysfunctions of
connected brain regions can be the source of these deficits. The aim of the present study …
