Directional Stimulus-Evoked Pallidal Electrophysiology in Primary Dystonia

Open Access
|Sep 2024

Abstract

Background: Deep brain stimulation for dystonia improves motor symptoms but variable and delayed responses challenge patient selection, targeting, and device programming.

Case Report: Here we studied intracranial electrophysiology in a patient with primary dystonia and observed evoked resonant neural activity (ERNA) in the globus pallidus interna. These local stimulus-evoked potentials displayed refractory periods and paired-pulse facilitation at clinically relevant interstimulus intervals. Sensing from directional DBS contacts localized ERNA to an effective stimulation site in the ventral posterolateral portion of the pallidum.

Discussion: To the best of our knowledge, this is the first observation of ERNA in the globus pallidus interna in a patient with primary dystonia. Stimulus-evoked activity could eventually guide both directional and adaptive stimulation for dystonia and other complex neuropsychiatric disorders.
