    Diagnostic value of vagus nerve ultrasound in Parkinson’s disease

    M. Abo Srea, N.A Kishk, R. Soliman, A. Alsayyad, M. Oraby (Beni-Suef, Egypt)

    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…
