Metabolic connectivity assessed by dynamic FDG-fPET acquisition in Parkinson’s disease: a multimodal fPET and fMRI study
Objective: To examine the spatial convergence of hemodynamic and metabolic network characteristics based on dynamic [18F]FDG-fPET acquisition Background: While fMRI reveals within-subject hemodynamics, [18F]FDG-PET traditionally…Cognitive flexibility associates with atrophy and disrupted connectivity of the cognitive cerebellum in degenerative cerebellar ataxia
Objective: This study was to investigate the features of cognitive flexibility in patients with degenerative cerebellar ataxia, and to identify the pathophysiological correlates of cognitive…Visual system abnormalities and visual hallucinations in Parkinson’s disease
Objective: We aimed to identify clinical and imaging biomarkers of visual system injury associated with the presence of Visual hallucinations (VH) in Parkinson's disease (PD).…Olfactory Network Reorganization in Parkinson’s Disease
Objective: To explore changes in the organization and functionality of the olfactory network in patients with Parkinson’s Disease (PD) using graph theory-based network analysis on…Machine learning-based classification of SCA1, SCA2, and Healthy controls using graph features
Objective: To differentiate genetic variants of spinocerebellar ataxia (SCA1 and SCA2) and healthy controls using machine learning on resting-state functional Magnetic Resonance Imaging graph features.…Brain structure alternations and disrupted functional connectivity in paroxysmal kinesigenic dyskinesia
Objective: This study aimed to delineate the morphological and functional alterations of paroxysmal kinesigenic dyskinesia (PKD) by functional magnetic resonance imaging (fMRI). Background: PKD is…Color vision deficits in Parkinson’s disease are linked to brain abnormalities in attentional, fronto-pariental and visual networks
Objective: To analyze the relationship between color vision deficits in Parkinson’s disease (PD) and the integrity of the visual system, cognition and other relevant networks…Cerebro-cerebellar motor networks in clinical subtypes of Parkinson’s disease
Objective: This study investigated functional alterations within the cerebro-cerebellar system in tremor-dominant (TD) and postural-instability-and-gait-disorder (PIGD) subtypes of Parkinson’s disease (PD) using stepwise functional connectivity…Altered Brain Connectivity in Hyperkinetic Movement Disorders: Systematic Review of Resting-State fMRI Studies
Objective: Providing a comprehensive literature review of resting-state brain connectivity alterations using resting-state fMRI (rs-fMRI) in hyperkinetic movement disorders (HMD). We additionally discuss alterations from…Resting state functional brain networks associated with emotion processing in frontotemporal lobar degeneration
Objective: This study investigated the relationship between emotion processing and resting-state functional connectivity (rs-FC) of the brain networks in frontotemporal lobar degeneration (FTLD). Background: Defective…
