    Machine learning selects common fMRI features of cognitive impairment in Parkinson’s disease from cross-institution datasets

    CY. Chien, TY. Lin, TL. Lee, CCK. Lin (Tainan, Taiwan)

    Objective: To obtain common features of Parkinson's disease (PD) with cognitive impairment (CI) in resting-state functional MRI (rs-fMRI) from cross-institution datasets by adopting machine learning.…

    The role of the default mode network and striatal circuits in the expression of depressive symptoms in premanifest Huntington’s disease

    T. Barta, L. Novelli, N. Georgiou-Karistianis, J. Stout, S. Loi, Y. Glikmann-Johnston, A. Razi (Clayton, Australia)

    Objective: This study aimed to investigate changes in large-scale network effective connectivity of the default mode network (DMN) and striatum in the expression of depression…

    Individual-specific brain functional connectivity mapping of therapeutic response in task-specific focal dystonia

    E. Gordon, K. Matthews, A. Meyer, S. Norris (St. Louis, USA)

    Objective: Determine therapeutic effects of botulinum toxin on functional connectivity in individuals with task-specific dystonia. Background: Isolated task-specific dystonia occurs during specific activities, but not…

    Functional circuit abnormalities in Levodopa-induced dyskinesia in Parkinson’s disease: A systematic review

    B. Thomsen, M. Vinding, D. Meder, L. Marner, A. Løkkegaard, H. Siebner (Hvidovre, Denmark)

    Objective: Levodopa-induced dyskinesia (LID) in Parkinson’s disease (PD) are involuntary movements caused by long-term treatment with dopaminergic replacement therapy (levodopa). During the cause of PD,…

    Multimodal neuroimaging to probe brain networks in Cervical Dystonia.

    SR. Bostan, R. King, C. Fearon, M. Hutchinson, R. Reilly (Dublin, Ireland)

    Objective: We employed a multimodal approach to gain a comprehensive understanding of the pathophysiology of cervical dystonia. The aim was to assess behavioural, microstructural, and…
