    Brain metabolism associated with clinical feature in patients with multiple system atrophy

    S. Lee, S. Jo, J. Lee, S. Chung (Seoul, Republic of Korea)

    Objective: We aim to investigate how structural metabolism of the brain affects survival in patients of multiple system atrophy (MSA). Background: Multiple system atrophy (MSA)…

    Blood NfL can track progression in multiple system atrophy

    V. Chelban, A. Perez-Soriano, C. Wilke, A. Foubert-Samier, N. Vijiaratnam, T. Guo, E. Jabbari, K. Senkevich, B. Laurens, P. Péran, O. Rascol, L. Schöls, C. Kobylecki, M. Hu, J. Rowe, T. Foltynie, N. Wood, A. Heslegrave, H. Zetterberg, M. Bocchetta, J. Rohrer, M. Marti, M. Synofzik, H. Morris, W. Meissner, H. Houlden (London, United Kingdom)

    Objective: To validate the role of NfL for disease progression, severity and subject trial selection in MSA. Neurofilament light (NfL) was explored in this regard though…

    Preliminary evidence for evolution of myoinositol and N-acteylaspartate as biomarkers of disease severity in early-stage multiple system atrophy

    P. Trujillo, J. Iregui, K. Hett, A. Wynn, M. Donahue, C. Wong, D. Stamler, D. Claassen (Nashville, USA)

    Objective: To quantify the longitudinal evolution of metabolic indicators of gliosis and neuronal integrity in patients with multiple system atrophy (MSA) over one year. Background:…

    Natural history and disease progression biomarkers of multiple system atrophy: the ASPIRE-MSA study

    N. Del Campo, P. Péran, P. Payoux, V. Rousseau, A. Drif, H. Catalá, C. Thalamas, C. Tranchant, F. Duriff, A. Marques, JP. Azulay, C. Moreau, JC. Corvol, S. Thobois, AG. Corbille, S. Frismand, B. Patterson, A. Foubert-Samier, A. Pavy-Letraon, M. Fabbri, W. Meissner, O. Rascol (Toulouse, France)

    Objective: To evaluate multiple system atrophy (MSA) disease progression on a panel of candidate MSA biomarkers pre-selected for their putative involvement in the pathophysiology of…

    Tracking longitudinal changes in MSA: TALISMAN study protocol

    W. Meissner, A. Varrone, A. Sahib, D. åström, J. Clarimon, A. Andreasen, A-K. Berger, J. Wiedemann, S. Sgarbi, D. Meulien (Pessac, France)

    Objective: The European (EU) TALISMAN study will retrospectively and prospectively explore disease progression and the correlation with plasma neurofilament light chain (p-NfL) and brain MRI…
