Gray/white matter contrast loss correlates with clinical severity and visuospatial impairment in Parkinson’s disease patients
Objective: The aim of our study was to test if PD patients differ from healthy controls (HC) in GWR and if this MRI parameter has…Tracking Parkinson’s disease over 2-6 years with MRI
Objective: To track Parkinson's progression over 2-6 years using global MRI measures. Background: Parkinson's is associated with accelerated brain atrophy, but the relative contribution of…A dynamic causal model of the superior colliculus: Inhibitory activity increases with the temporal discrimination threshold
Objective: To investigate if abnormalities observed in the putamen of unaffected first-degree relatives (of cervical dystonia patients) with abnormal temporal discrimination thresholds (TDT) are a…Imaging correlates of hypodipsia in progressive supranuclear palsy
Objective: Aims of the present study were• to confirm hypodipsia as a characteristic feature of PSP and• to offer hypothesis on the pathological substrate for…Different patterns of spontaneous brain activity between tremor-dominant and postural instability/gait difficulty subtypes of Parkinson’s disease: A resting-state fMRI study
Objective: This study aimed at investigating the subtype-specific patterns of spontaneous brain activity in PD. Background: Postural instability/gait difficulty (PIGD) and tremor-dominant (TD) subtypes of…Three-dimensional cytoarchitecture of the basal ganglia: Clinical applications of a computational pipeline for histology to MRI registration
Objective: Use modified histological techniques and a computational registration pipeline to delineate accurately post-operative 3D basal ganglia anatomy in DBS implants. Background: Stereotaxy is based…Arterial spin labeling perfusion MRI compensate for other diagnostic tools in evaluation of Parkinson’s disease with dementia
Objective: To test usefulness of arterial spin labeling (ASL) perfusion MRI for diagnoses of Parkinson's disease (PD) with dementia. Background: Dopamine transporter (DAT) images may…Corpus callosum thickness and area in Parkinson’s disease
Objective: To evaluate corpus callosum thickness and area in Parkinson's disease (PD) subjects and the relationship of these measures with cognitive impairment. Background: Many PD…Motor-related brain changes associated with acute administration of trihexyphenidyl in patients with cervical dystonia
Objective: The goal of the current study was to assess task-related brain activity in patients with cervical dystonia (CD) using functional magnetic resonance imaging (fMRI)…Dementia in Parkinson’s disease is associated with increased diffusivity in amygdala and external capsule
Objective: To identify which regions are associated with dementia in Parkinson's disease (PD) brains. Background: Dementia is common in advanced PD and its early development…
