In vivo MRI signatures of hippocampal subfield pathology in patients with Parkinson’s disease and psychosis
Objective: To study the role of hippocampal subfield pathology in the genesis of psychotic symptoms in patients with Parkinson's disease (PD) by comparing the volumes…Complementary value of MRI-based differential diagnosis in parkinsonism
Objective: We aimed to evaluate the complementary diagnostic values of MRI characteristics to differentiate various types of parkinsonism. Background: Although precise differential diagnosis of parkinsonism…Effect of levodopa on fronto-parietal network connectivity in freezing of gait in Parkinson’s disease
Objective: To investigate the effect of levodopa on fronto-parietal network (FPN) functional connectivity (FC) in Parkinson’s disease patients with (PD-FOG) and without freezing of gait…Gender-specific pattern of sensori-motor network connectivity in early untreated Parkinson’s disease patients
Objective: To investigate the presence of a disease-related gender effect on the spontaneous neuronal activity within the sensori-motor network (SMN) in early untreated Parkinson's disease…Discriminating Idiopathic PD Patients and Controls in PPMI Using Integrative Multi-Modal Neuroimaging Analysis with Graph Convolutions
Objective: To discriminate Parkinson’s disease (PD) patients and controls in the Parkinson’s Progression Markers Initiative (PPMI) cohort according to MRI features using a novel a…Assessing working memory dysfunction with letter n-back functional MRI task in early-stage Parkinson’s disease
Objective: To assess the dynamic brain responses during a working memory n-back fMRI task in an early-stage PD cohort with variable mild cognitive impairment Background:…The effect of age on Substantia Nigra Hyperechogenicity in PD patients and healthy controls
Objective: To analyze whether the size of SN+ is differentially affected depending on disease start side. Secondly to analyze the interaction between a range of…Effects of subthalamic nucleus deep brain stimulation in Parkinson’s disease are mediated by a prefronto-cerebellar-striatal loop
Objective: To determine DBS-related changes of a motor network using resting state fMRI in PD patients with chronic STN-DBS. Background: In Parkinson’s disease (PD), dopamine…Resting-state connectivity and cognitive changes in Parkinson’s disease: A four-year follow-up study
Objective: To study functional connectivity changes using graph theory and their association with cognitive evolution in a sample of non-demented Parkinson’s disease (PD) and matched…Resting state fMRI points to disparate brain network activations in early Parkinson’s disease
Objective: To perform an exhaustive comparison of brain networks identified through functional MRI (fMRI) in a small cohort of patients with idiopathic Parkinson’s disease (IPD)…
