Altered Resting-State Functional Interhemispheric Connectivity in Parkinson’s Disease
Objective: To examine direct interhemispheric functional connectivity (FCi) in Parkinson's disease (PD) during resting-state fMRI and to investigate the relations between observed connectivity changes and…Dopamine Normalizes Putamen to Insula Activation Shift During Choice Reaction Time Task in PD
Objective: We investigated Parkinson’s disease (PD) patients during a functional MRI Choice Reaction Time (CRT) task and determined whether brain activations are altered by dopamine. Background:…EEG Markers for Emotional Inhibition in Parkinson’s Disease
Objective: This study aims to advance understanding of neural mechanisms in Parkinson’s disease (PD) using event related potentials (ERPs) generated during emotional response inhibition and…The Putamen to Caudate Nucleus Ratio: A Simple Surrogate Marker for Dopaminergic Volume in Putamen
Objective: To investigate the simple parameter by which fully represent the level of nigral dopamine in putamen by means of routine 18F-FP-CIT positron emission tomography…The brain plasticity for controlling reach-to-grasp functions of Parkinson’s disease
Objective: To investigate the brain plasticity for controlling the dominant and non-dominant hand muscles and reach-to-grasp (RTG) functions in Parkinson’s disease (PD). Background: Previous studies…Sleep disturbance may alter white matter and resting state functional connectivities in Parkinson’s disease
Objective: To clarify whether sleep disturbance would alter the patterns of structural and functional networks underlying cognitive dysfunction in patients with Parkinson’s disease (PD). Background:…Olfactory Impairment in Parkinson’s Disease and White Matter Abnormalities in Central Olfactory Areas
Objective: To determine white matter abnormalities in PD patients with various degrees of olfactory impairment. Background: Neuroimaging results of PD brain based on diffusion tensor…The influence of LRRK2 mutations on cholinergic system in manifest and prodromal stage of Parkinson’s disease: a positron emission tomography study
Objective: To evaluate the effects of leucine-rich repeat kinase 2 (LRRK2) mutations on the central cholinergic system in both manifesting and non-manifesting carriers using PET…Functional MAOB gene intron 13 polymorphism predicts putaminal dopamine turnover in de novo Parkinson’s disease
Objective: To examine the effects of common functional polymorphisms in genes involved in dopamine metabolism on striatal dopamine turnover estimated as the inverse of the…Substantia nigra area evaluated by neuromelanin-sensitive MRI as an imaging biomarker of disease progression in Parkinson’s disease
Objective: to investigate the pattern of substantia nigra - neuromelanin (SN-NM) area loss and contrast ratio (CR) intensity changes in late-stage Parkinson’s disease (LSPD) patients,…
