Altered metabolic and functional resting state activity in cognitively unimpaired and impaired Parkinson’s disease patients
Objective: To assess the correspondence between functional connectivity and metabolic covariance in healthy controls and Parkinson’s disease patients (PD) with and without cognitive impairment. Background:…Non-motor network decoupling accompanies conversion to freezing of gait in Parkinson’s disease
Objective: To investigate the resting state connectivity in cortico-striatal-thalamo-cortical networks pre-conversion and pre- to post-conversion to Freezing of Gait in Parkinson’s disease. Background: Freezing of…Abnormal network interconnections dynamics correlate with levodopa-induced dyskinesia in Parkinson’s disease
Objective: To explore the pathogenesis of dyskinesia, the present study was conducted to investigate that how large-scale functional network interactions change dynamically in the temporal…Intrinsic brain functional connectivity predicts treatment-related motor complications in drug-naive Parkinson’s disease patients
Objective: Using resting-state functional MRI, we investigated intrinsic brain networks connectivity at baseline in a cohort of drug-naïve Parkinson’s disease (PD) patients which successively developed treatment-related…Functional connectivity of brain autonomic centers reveals associations with cardiovascular autonomic dysfunction in Parkinson’s disease
Objective: To investigate differences in functional connectivity of key autonomic brain structures that distinguish those with orthostatic hypotension (OH) from those without among subjects with…Functional connectivity traits in Parkinson’s disease mild cognitive impairment
Objective: Our objective is to assess functional networks in PD mild cognitive impairment (PD-MCI) and their contribution to global connectivity combining Connectome ICA (connICA) and…Impairment of the mesocortical dopamine system in Parkinson’s disease patients with freezing of gait in a multimodal imaging approach
Objective: To investigate the involvement of dopaminergic systems in Parkinson’s disease (PD) patients with freezing of gait (FOG) using a multimodal assessment involving 18 F-DOPA-PET…Sex differences on dynamic functional connectivity in Parkinson’s disease and healthy controls
Objective: The main objective was to evaluate the influence of sex in time-varying functional connectivity (FC) characteristics in Parkinson’s disease (PD) patients and healthy adults…Neural Correlates of Semantic Fluency Deficits in Parkinson’s Disease with Mild Cognitive Impairment
Objective: To explore neural mechanisms related to semantic fluency deficits in Parkinson’s disease (PD). Background: Verbal fluency impairments are the earliest and typical cognitive deficits…Biomarkers of the Level of Cognitive Impairment (CI) in patients with Parkinson’s Disease (PD): MRS study
Objective: The concentrations of NAA, Cr, mIns, and Glx are identified as putative neurochemical markers of CI in patients with PD. Background: On the basis…
