Association of Pallidal Neurostimulation and Outcome Predictors With X-linked Dystonia Parkinsonism

Abstract

Internal globus pallidus DBS had a positive association in XDP with predominant dystonia (the primary end point) and contributed to an improved quality of life (the secondary end point). The response to DBS occurred within 1 week. Given the inverse correlation of postoperative benefit and caudate atrophy, GPi-DBS should be considered early during the disease course. Close international collaboration, training, and funding from multiple sources enabled the sustainable follow-up of patients with XDP in the Philippines.
