    Regional free-water differentially associated with glial activation, neuroinflammation, and neurodegeneration in de novo Parkinson’s disease

    D. Tosun, R. Ellis (San Francisco, CA, USA)

    Objective: Assess to what extent free-water(FW) as measured by diffusion-weighted MRI(dMRI) is a neuroimaging marker of glial activation, neuroinflammation, and neurodegeneration in de novo Parkinson’s disease(PD) patients from…

    Neurosonography of substantia nigra in patients with isolated essential tremor and in association with Parkinson’s disease of the family nature

    S. Munasipova, Z. Zalyalova (Kazan, Russian Federation)

    Objective: To identify differential clinical and neurosonographic criteria for ET and PD in patients with familial ET. Background: ET and PD are common disorders, especially…

    The Use of Diffusion Weighted Imaging to Detect Structural Biomarkers in Recently-Diagnosed Parkinson’s Disease Patients

    P. Macdonald, N. Handfield-Jones, E. Alushaj, N. Hiebert, A. Owen, A. Khan (London, ON, Canada)

    Objective: To quantify biomarkers for recently-diagnosed PD patients in the midbrain and their dopaminergic connections to the striatum. Background: The development of improved PD treatments…

    Correlation between substantia nigra measurement and UPDRS

    N. Mohammadzade, F. Omrani, A. Habibi (Tehran, Islamic Republic of Iran)

    Objective: Parkinson is mainly developed due to neurodegeneration of substantia nigra pars compacta (SNpc).the aim of our study was to check if there is any correlation between the size…

    Longitudinal Change of Substantia Nigra Hyperechogenicity in Parkinson’s Disease Cohort

    T. Toomsoo, I. Rubanovits, R. Kerner, T. Asser, M. Vähi, P. Taba (Tallinn, Estonia)

    Objective: To analyze whether the size of SN+ is differentially affected depending on disease duration. Secondly to analyze the interaction between a range of clinical…

    Targeted deep sequencing of brain DNA for detection of somatic point mutations in synucleinopathies

    M. Leija-Salazar, A. Pittman, K. Mokretar, A. Schapira, C. Proukakis (London, United Kingdom)

    Objective: To detect relevant somatic "point mutations" (single nucleotide variants- SNVs) in brain-derived DNA in synucleinopathies. Background: There is increasing recognition that neurons may harbour…

    Sequencing of single human nigral dopaminergic neurons for somatic copy number variants

    D. Perez-Rodriguez, M. Kalyva, S. Santucci, K. Mokretar, M. Leija-Salazar, A. Schapira, T. Lashley, J. Holton, C. Proukakis (London, United Kingdom)

    Objective: To detect somatic DNA copy number variants (CNVs) in dopaminergic neurons isolated from human substantia nigra, using shallow whole genome sequencing (WGS). Background: Somatic…

    The trace of substantia nigra hyperechogenicity: a clinical observation

    A. Alonso-Canovas, JL. Sendon-Moreno, G. Garcia-Ribas, N. Monterde-Gonzalez, C. Jara-Laguna, JC. Martinez-Castrillo, J. Masjuan (Madrid, Spain)

    Objective: To present an empirical observation regarding transcranial ultrasound in movement disorders and scalp sebum smear. Background: Transcranial ultrasound (TUS) detects substantia nigra hyperechogenicity (SN+) in…
