An Eyes-Open/Closed Manipulation Reveals Disrupted Default Mode Network Connectivity in Parkinson’s Disease and REM Sleep Behavior Disorder
Objective: To spatially localize disruptions in default mode network connectivity in prodromal and diagnosed Parkinson’s disease relative to controls. Background: Previously our research team reported…Altered functional activity of the motor system related to ankle and hand movements in Parkinson’s disease: insights from functional MRI
Objective: Examine functional magnetic resonance imaging (fMRI) activity during hand and foot force production tasks in Parkinson’s disease (PD). Background: Previous MRI studies in PD…Relationship Between Hyposmia and Olfactory Network Connectivity in Patients With Parkinson’s Disease
Objective: To examine resting-state functional Magnetic Resonance Imaging in a group of Parkinson’s Disease patients, used to characterize changes in functional connectivity of the olfactory…The neural correlates of dynamic balance control in Parkinson’s disease and freezing of gait
Objective: To investigate the neural correlates of postural control in Parkinson’s disease (PD) with and without freezing of gait (FOG) as compared to healthy older…Longitudinal structural and functional brain alterations in Parkinson’s disease patients with freezing of gait
Objective: To investigate the cortical/subcortical grey matter (GM) changes and network functional alterations in PD-FoG patients, in PD developing FoG (PD-FoG-converters) and PD not developing…Neural correlates of executed compared to imagined writing and drawing movements. An fMRI study
Objective: In this study we used functional magnetic resonance imaging (fMRI) to investigate whether motor imagery (MI) of handwriting and circle drawing activates a similar…Altered functional connectivity of the hippocampus in posterior-cortical subtype of cognitive impairment in Parkinson’s disease
Objective: We aimed to delineate the dual syndrome subtypes of PD-MCI using a data-driven approach and explore hippocampal functional connectivity of the posterior-cortical syndrome. Background:…In vivo relationship between synaptic density and functional connectivity in progressive supranuclear palsy: a multimodal [11C]UCB-J PET and resting state fMRI study.
Objective: To assess the relationship between synaptic density and functional connectivity in the primary tauopathy of Progressive Supranuclear Palsy (PSP). Background: PSP is a debilitating…Brain activity of the emotional circuit in Parkinson’s disease patients with freezing of gait
Objective: The aim of this observational study was to assess brain functional MRI (fMRI) activity during a “FoG observation task” in PD-FoG patients relative to…The dual cognitive syndrome in Parkinson’s disease: a resting-state functional connectivity study
Objective: To assess resting-state functional connectivity modifications characterizing the frontostriatal and posterior cortical cognitive subtypes in Parkinson’s Disease (PD) Background: The dual syndrome hypothesis (Kehagia…
