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.
