White matter microstructural differences between essential tremor and Parkinson’s disease evaluated using advanced MRI biomarkers
Objective: To study white matter differences between essential tremor (ET) and Parkinson’s disease (PD) using standard diffusion tensor magnetic resonance imaging (DTI) and fixel-based analysis.…Adrenergic blockers and statins are associated with later age of onset in Parkinson’s disease
Objective: To evaluate the association of anti-hypertensives, non-steroidal anti-inflammatories (NSAIDs), statins, diabetes medications, smoking and family history of idiopathic Parkinson’s disease (iPD) with age of…Characterization of neuromelanin MRI as a potential Parkinson’s Disease biomarker in a multi-site longitudinal study
Objective: To investigate (1)longitudinal change and (2)cross-sectional vendor differences in neuromelanin MRI in substantia nigra pars compacta(SNpc) in PD patients. Background: Neuromelanin(NM) MRI is a…Dopaminergic modulation of express reaching responses in Parkinson’s disease
Objective: This study investigates the role of dopamine (DA) in modulation of automatic stimulus-driven responses. We investigated the effect of PD, DA medication, and instruction…Psychosis in Parkinson’s disease and polymorphisms of the HOMER1 and COMT genes: Is there an association?
Objective: To investigate if polymorphisms of the HOMER1 and COMT gene are associated with psychosis in Parkinson’s disease (PD). Background: Psychosis is one of the…The brain-age framework in Parkinson’s disease: evaluating MRI morphometry and sex-dimorphism
Objective: We aimed to develop an MRI brain-age prediction (BAP) model to evaluate differences between Parkinson’s disease (PD) and healthy controls (HC). We further evaluated…The Vall d’Hebron Initiative for Parkinson (VHIP) cohort: a prospective, longitudinal and observational study enrolling de novo Parkinson’s disease (PD) patients and carriers of PD-linked mutations for biomarker and pathophysiology studies
Objective: To describe the study protocol of the Vall d’Hebron Initiative for Parkinson (VHIP) cohort, a prospective, longitudinal and observational cohort study aimed at deeply…The distinctive functional connectivity of the cholinergic nucleus basalis of Meynert in Parkinson’s disease across different motor subtypes
Objective: We aim to compare the state of cortical-NBM functional connectivity across healthy control (HC), PIGD-predominant PD (PIGD-PD), and tremor-dominant PD (TD-PD). Additionally, the correlation…The Correlation Analyses of Parkinson’s Disease with Serum Homocysteine, Folic Acid and Vitamin B12
Objective: To explore the associations of serum homocysteine (Hcy), folic acid (FA) and vitamin B12 (VitB12) levels with the severity of Parkinson's disease (PD), as…Turning during single and dual tasking in Parkinson’s Disease
Objective: To investigate turning kinematics and intersegmental coordination in single (ST) and dual tasking (DT) in Parkinson’s Disease (PD) patients. Background: Successful turning depends on…
