    Non-motor network decoupling accompanies conversion to freezing of gait in Parkinson’s disease

    N. D'Cruz, S. Chalavi, M. Gilat, A. Nieuwboer (Leuven, Belgium)

    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…

    Elevated nigral iron is associated with low plasma serotonin in Parkinson’s disease

    L. Jellen, A. Snyder, G. Du, M. Lewis, E. Wang, C. Capan, P. Brundin, L. Brundin, J. Connor, X. Huang (Hershey, PA, USA)

    Objective: The objective of this work was to determine whether plasma serotonin levels in Parkinson’s disease (PD) are related to iron levels in the brain,…

    Functional connectivity of the basal ganglia in tremor dominant and non-tremor dominant Parkinson’s disease

    S. Prasad, J. Saini, R. Bharath, P. Pal (Bengaluru, India)

    Objective: To explore differences in functional connectivity of the basal ganglia in tremor dominant and non-tremor dominant Parkinson’s disease (PD) using seed-to-voxel based resting state…

    Abnormal network interconnections dynamics correlate with levodopa-induced dyskinesia in Parkinson’s disease

    Q. Si, Y. Yuan, C. Gan, M. Wang, L. Wang, K. Ma, K. Zhang (Nanjing, China)

    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…

    Progression of cortical thinning in Parkinson’s disease

    A. Vo, C. Tremblay, S. Rahayel, Y. Yau, A. Dagher (Montréal, QC, Canada)

    Objective: We sought to validate cortical thickness as an objective biomarker of Parkinson’s disease (PD) progression. Background: Cortical thickness analysis has been proposed as a…

    Asymmetrical cochlear dysfunction as a lateralized non-motor feature in Parkinson’s disease

    R. Cerroni, A. Viziano, R. Sisto, A. Moleti, N.B Mercuri, A. Stefani, M. Pierantozzi (Rome, Italy)

    Objective: We evaluated hearing function in a population of PD patients to investigate: 1) the occurrence of hearing loss; 2) the possible lateralization of hearing…
