Presynaptic dopamine depletion determines the timing of levodopa-induced dyskinesia onset in Parkinson’s disease
Objective: To investigated whether dopaminergic function in the nigrostriatal system is associated with the timing of levodopa-induced dyskinesia (LID) onset in Parkinson's disease (PD). Background:…Amyloid PET and cognition in Parkinson’s disease
Objective: To investigate the relationship between cerebral amyloid accumulation and cognition in Parkinson’s disease (PD). Background: The neuropathology underlying the development of dementia in Parkinson’s…Comparisons of cerebral glucose metabolism and striatal DAT binding in PD patients with and without RBD
Objective: This study aims to identify the differences of functional neuroimaging phenotype between Parkinson’s disease (PD) patients with REM sleep behavior disorder (RBD) (PD+RBD+) and…In vivo staging of pathology in REM sleep behaviour disorder
Objective: To study the level of dysfunction in the peripheral and central nervous system in idiopathic REM sleep behaviour disorder (iRBD) patients. Background: α-synuclein (α-syn)…Automated Differential Diagnosis of Parkinsonian Syndromes Using FDG-PET Metabolic Brain Network Analysis
Objective: To discriminate among parkinsonian patients using an automated network analysis of FDG-PET brain images. Background: Clinical differentiating among parkinsonian syndromes: Parkinson’s disease (PD), multiple…A Florbetapir [F18] amyloid PET Imaging study in Parkinson’s disease Dementia (PDD): The influence of amyloid deposition on cognitive status and course of disease progression
Objective: To determine whether amyloid deposition, as assessed by PET imaging with the [18F]-Florbetapir, is related in patients with Parkinson Disease and Dementia (PDD) to…α4β2-nicotinic receptor availability in Parkinson’s disease MCI and healthy controls: A pilot imaging study using [18F]-XTRA PET
Objective: We aimed to show that a radiotracer with high affinity to cortical and hippocampal α4β2-nicotinic cholinergic receptors (1) would be reduced in regions associated…Dopaminergic dysfunction and abnormal metabolic network activity in REM sleep behavior disorder
Objective: This study is to investigate the correlations between the abnormalities in the distribution of striatal dopamine transporter (DAT) and the expression of Parkinson's disease…Combining PET imaging and blood metabolomics data to improve machine learning models for Parkinson’s disease diagnosis
Objective: To investigate whether the integration of PET imaging and metabolomics data can provide improved machine learning models for PD diagnosis. Background: The reliable diagnosis…Hypometabolism of the posterior parietal cortex in Parkinson’s disease with mild cognitive impairment predicts the conversion to dementia: 5-year longitudinal observations
Objective: To investigate the neuroimaging marker that predict the conversion of mild cognitive impairment (MCI) to dementia in Parkinson’s disease (PD) patients. Background: Patients with…
