Characteristics of the amyloid beta networks in Parkinson’s disease patients: a PPMI study
Objective: The impact that amyloid beta (Aβ) accumulation in the brain has on the progression of Parkinson’s disease (PD) pathology is complex and poorly understood…The association of β-amyloid with cognition and striatal dopamine in early, non-demented Parkinson’s disease
Objective: The purpose of this study was to investigate the association among striatal dopaminergic availability, Aβ-positivity, and motor and cognitive status in early and non-demented…Sex differences in brain and cognition in de novo PD patients
Objective: We aimed to investigate sex differences in brain atrophy and cognition in PD de novo patients through MRI subcortical volumetry and cortical thickness (CTh).…DAT-SPECT in old onset Parkinson’s disease: should we trust?
Objective: . Background: Scans without evidence of dopaminergic deficit (SWEDD) refers to patients clinically diagnosed with Parkinson’s disease (PD), but show normal findings on dopamine…Developing 31-phosphorus magnetic resonance spectroscopy (31P-MRS) as an imaging biomarker to identify mitochondrial dysfunction in Parkinson’s disease
Objective: To determine if 31P-MRS can identify mitochondrial dysfunction in-vivo and if this correlates with in-vitro measures of mitochondrial function obtained from patient derived fibroblasts…Relationship Between Hyposmia and Olfactory Network Connectivity in Patients With Parkinson’s Disease
Objective: To examine resting-state functional Magnetic Resonance Imaging in a group of Parkinson’s Disease patients, used to characterize changes in functional connectivity of the olfactory…Longitudinal structural and functional brain alterations in Parkinson’s disease patients with freezing of gait
Objective: To investigate the cortical/subcortical grey matter (GM) changes and network functional alterations in PD-FoG patients, in PD developing FoG (PD-FoG-converters) and PD not developing…Clinical and transcranial sonography characteristics in benign phenotype of Parkinson’s disease.
Objective: To investigate clinical and transcranial B-mode sonography (TCS) characteristics of benign phenotype of Parkinson’s disease (bPD). Background: Parkinson’s disease (PD) progression is heterogeneous. A…Altered functional connectivity of the hippocampus in posterior-cortical subtype of cognitive impairment in Parkinson’s disease
Objective: We aimed to delineate the dual syndrome subtypes of PD-MCI using a data-driven approach and explore hippocampal functional connectivity of the posterior-cortical syndrome. Background:…Dissociated longitudinal evolution of limbic serotonergic and striatal dopaminergic and serotonergic pathology in apathetic and non-apathetic patients in early Parkinson’s disease
Objective: To investigate the longitudinal changes in striatal and extra-striatal dopaminergic and serotonergic innervation in apathetic and non-apathetic patients during the five years after the…
