The 20th International Congress of Parkinson’s Disease and Movement Disorders was held June 19-23 in Berlin, Germany with more than 5,000 attendees. Seven focused ultrasound abstracts were presented, including the latest preliminary study data for Parkinson’s tremor and essential tremor.
Read the Abstracts
An international, randomized, sham controlled trial of focused ultrasound thalamotomy for essential tremor by W Ondo et al. (Houston, TX, USA). Objective: To determine efficacy and safety of unilateral focused ultrasound thalamotomy for refractory essential tremor. Noticed by Medscape.
Unilateral MR-guided high intensity focused ultrasound ablation of the cerebellothalamic tract in essential tremor by SR Schreglmann et al. (London, United Kingdom). Objective: To report interim results of an ongoing trial of unilateral transcranial MR-guided high intensity focused ultrasound (tcMRgFUS) ablation of the cerebellothalamic tract (CTT).
Unilateral focused ultrasound thalamotomy in tremor-dominant Parkinson’s disease by BB Shah et al (Charlottesville, VA, USA). Objective: To evaluate the safety, feasibility, and durability of focused ultrasound thalamotomy on tremor in PD. Noticed by Neurology Today.
MR-guided high intensity focused ultrasound in Parkinson’s disease: A series of 5 cases by N Wegener et al (St. Gallen, Switzerland). Objective: We present results of an ongoing trial of unilateral transcranial MR-guided high intensity focused ultrasound (tcMRgFUS) ablation of the pallido-thalamic tract (PTT, fasciculus thalamicus).
Transcranial unilateral MR guided high intensity focused ultrasound in Parkinson’s disease or essential tremor seems to be safe concerning dysphagia and dysarthria by S Hägele-Link et al (St. Gallen, Switzerland). Objective: To report first results of a study monitoring speech and swallowing function after lesional functional neurosurgery for movement disorders.
MRI guided high-intensity focused ultrasound for the treatment of essential tremor and Parkinson’s disease: Clinical outcome and radiological findings of unilateral thalamotomy by R Martínez-Fernandez et al (Madrid, Spain). Objective: To report our clinical experience in the treatment of essential (ET) and Parkinson’s disease (PD) tremor with MRI guided High-Intensity Focused Ultrasound (MRgHIFU).
Focusing precision and lesion size in cerebello-thalamo-tractotomy by MR imaging-guided high intensity focused ultrasound (MRgFUS) by RG Bauer et al (St. Gallen, Switzerland). Objective: Focusing precision in tcMRgFUS tractotomy depends on the ability of the treatment system to compensate for acoustic field distortions induced by the patient skull.
