    Glucocerebrosidase Deficiency Mediates Propagation of Protein Aggregation via Extracellular Vesicle Dysregulation

    K. Jewett, R. Thomas, C. Phan, G. Milstein, S. Yu, L. Pallanck, M. Davis (Seattle, WA, USA)

    Objective: Investigate a role for GBA in accelerating the spread of protein aggregates via extracellular vesicles (EVs). Background: Parkinson’s disease (PD) progression correlates with temporo-spatial…

    miRNA sequencing from routine colonic biopsies reveals an enrichment of submucosal hsa-miRNA-486-5p in Parkinson’s disease

    A. Kurz, R. Kumar, C. Wenk, B. Nordhoff, J. Schirra, S. Donakonda, G. Höglinger, K. Bötzel, L. Holdt, T. Koeglsperger (Munich, Germany)

    Objective: In the present work, we aimed to investigate the expression of microRNAs (miRNAs) in routine colonic biopsies obtained from patients with idiopathic Parkinson's disease…

    An agent-based model replicates the pathogenic spread of alpha-synuclein in mice

    S. Rahayel, B. Mišić, Y.Q Zheng, Z.Q Liu, A. Caputo, K. Luk, A. Dagher (Montreal, QC, Canada)

    Objective: To investigate the ability of a susceptible-infected-removed (SIR) agent-based model to predict the pathogenic spread of alpha-synuclein fibrils after injection in mice. Background: Parkinson’s…

    Difference in distribution between alpha-synuclein oligomers and Lewy bodies in Parkinson’s disease brain

    H. Sekiya, H. Kowa, Y. Hashimoto, M. Takata, R. Matsumoto, T. Toda (Kobe, Japan)

    Objective: To examine the distribution of alpha-synuclein (αSYN) oligomers in Parkinson’s disease (PD) brains and compare the distribution of αSYN oligomers and Lewy bodies. Background:…

    The exosomal a-syn filaments can be a novel biomarker of Parkinson’s disease

    Y. Ishiguro, T. Tsunemi, A. Yoroisaka, N. Hattori (Tokyo, Japan)

    Objective: This study is aimed to investigate whether the number of exosomes, the amount of total or exosomal a-synuclein (a-syn) filaments in serum can serve as…
  • 2019 International Congress

    A possible case of prodromal DLB with prominent hallucinations, autonomic dysfunction, and REM behavior disorder but absence of cognitive impairment

    K. Amodeo (Rochester, NY, USA)

    Objective: Dementia with Lewy bodies (DLB) is the second most common cause of neurodegenerative dementia, after Alzheimer’s disease (AD). While mild cognitive impairment (MCI) is…
  • 2019 International Congress

    A Lewy body disease of widely confirmed Lewy bodies in the cerebral cortexes including the occipital lobe without pathological changes in the hippocampal CA2/3 region

    M. Ryo, K. Hasegawa, I. Saitoh, S. Yagishita (Tokyo, Japan)

    Objective: We present Lewy body disease (LBD) showing unique neuropathological findings which are widely recognized Lewy bodies (LBs) in the cerebral cortexes including the occipital…
  • 2019 International Congress

    New Neuropathological Staging System for Lewy Body Disease

    J. Toledo, L. Walker, J. Trojanowski, I. Mckeith, J. Attems (Houston, TX, USA)

    Objective: Present the validation of the new proposed novel staging system (NSS) for Lewy body disease and compare it against the previously proposed staging systems. Background:…
  • 2019 International Congress

    Comparing motor and neuropathological features of Parkinson’s disease dementia and dementia with Lewy bodies

    D. Hansen, T. Lashley, J. Holton, T. Warner (London, United Kingdom)

    Objective: To compare motor and neuropathological features of Parkinson’s disease dementia (PDD) and dementia with Lewy bodies (DLB) and to determine clinical and neuropathological differences…
  • 2019 International Congress

    Prodromal symptoms in clinically diagnosed dementia with Lewy bodies stratified by Lewy body pathology on autopsy

    K. Wyman-Chick, D. Weintraub, M. Rosenbloom, L. Erickson, P. Martin, T. Barclay, M. Barrett (Bloomington, MN, USA)
