Increasing Evidence for the Use of Sodium Oxybate in Multi-Drug-Resistant Lance–Adams Syndrome

Abstract

Background: Treatment of posthypoxic myoclonus (PHM) can be a challenge in patients not responsive to first-line medications. PMH is a rare condition that has a dramatic impact on patients’ quality of life. Refractory cases are not uncommon. Case report: We report a patient with PHM non-responsive to conventional treatments who showed a dramatic improvement with sodium oxybate (SBX). Cases of PHM treated with SBX reported in the literature were reviewed. Discussion: Resting and stimulus-induced myoclonus respond robustly to SBX, with significant improvement in patients’ quality of life. SBX may be considered in patients with PHM resistant to first-line medications.
