Welcome to the WCN 2023 Interactive Program

Session Description: Ultrasound based methods-especially Color Codes Duplex Sonography- are today the basic screening tools for extra- und intracranial occlusive disease in symptomatic and asymptomatic patients.The diagnosis and follow-up -after treatment-of Carotid and Vertebral Artery Disease and of Intracranial Stenosis and Occlusion will be described, also in correlation with reference methods like MR- or CT-angiography.TCD Monitoring of vasospasm following Subarachnoid Hemorrhage is an important tool in the management of this life-threathening disease. The method with refence values and case exaples is described.Ultrasound is also essential in the non-invasive diagnosis of Non-Atherosclerotic Vasculopathies like Dissection and Giant Cell Arteriitis. Advanced high-resolution ultrasound methods are applied and case examples presented. Learning Objectives: 1. to be able to detect the fasciculation more accurately, to differentiate myopathies based on structural changes (perimysium, swelling, inclusion bodies, muscle destruction pattern and so on), and to determine the biopsy site correctly .2. to be able to differentiate neuropathies (demyelination neuropathies, metabolic neuropathies, inherited neuropathies, and so on), and to detect the site of lesion in compression neuropathies based on neuro-sonography findings (swelling, atrophy, axonal structural changes, myelin changes and so on). 3. to be able to consider all already known possibilities in differential diagnosis in neuro-muscular disorders based on an excellent review of previously reported results of neuro-muscular sonography. 

Session Description: Ultrasound examination of muscle and nerve usually supports or confirms the diagnosis suspected by clinical neurological examination. It has become one of routine examinations and widely applied in patients with peripheral nerve/muscle disorders because of its repeatability, non-invasiveness, and easiness of performing. In this session, we will briefly describe ultrasonography of muscle/nerve, and will show that its outcomes in association with electrophysiological and MRI findings help us make a diagnosis and select the treatment in patients with peripheral neuropathy or muscular disorders. Basic detailed anatomical knowledge for understanding muscle and nerve sonography will be first shown by two speakers, and the review of many already reported clinical utilities of neuro-muscular sonography will be presented by a world-wide well known specialist of this field. Leaning objectives: 1. to be able to detect the fasciculation more accurately, to differentiate myopathies based on structural changes (perimysium, swelling, inclusion bodies, muscle destruction pattern and so on), and to determine the biopsy site correctly. 2. to be able to differentiate neuropathies (demyelination neuropathies, metabolic neuropathies, inherited neuropathies, and so on), and to detect the site of lesion in compression neuropathies based on neuro-sonography findings (swelling, atrophy, axonal structural changes, myelin changes and so on).3. to be able to consider all already known possibilities in differential diagnosis in neuro-muscular disorders based on an excellent review of previously reported results of neuro-muscular sonography.

Session Description:The hereditary progressive ataxias comprise a large and diverse group of neurodegenerative disorders. This session aims to provide an overview of recent advances in understanding the genetic basis and pathogenesis of selected hereditary ataxias, as well as how these insights have informed the development of potential therapies. Additionally, the session will explore how natural history and biomarker studies are contributing to the design of more effective clinical trials. Session Objectives :1. Understand the pathogenesis of selected hereditary ataxias in greater depth.2. Describe how natural history and biomarker studies can inform the design of clinical trials for ataxia treatments.3. Stay up to date on the latest therapeutic developments in the field of ataxia.
