Abstract

X-linked dystonia-parkinsonism (XDP) is an adult-onset debilitating neurodegenerative disorder presenting with
motor and nonmotor symptoms. The treatment options for XDP are limited. We described a patient with XDP who underwent a unilateral transcranial magnetic resonance-guided focused ultrasound (tcMRgFUS) pallidothalamic tractotomy with a one-year follow-up. The patient reported an immediate improvement in his pain after the procedure. Compared to baseline, there was an improvement in his scores in the dystonia (31%), parkinsonism (35.1%), and activities of daily living (71%) subscales at 1-year follow up. The overall improvement at one year was 46%. There were no adverse events noted. Additional studies with larger sample size and follow-up would be needed to document its long-term safety and efficacy.
