Long-Term Effect of Sodium Oxybate (Xyrem®) in Spasmodic Dysphonia with Vocal Tremor
Background: Symptoms of spasmodic dysphonia (SD) are usually managed successfully with botulinum toxin injections. Vocal tremor (VT), which accompanies SD, has a poor response to this treatment. Case Report We report a case of a female with SD and VT who became symptom‐free for 10 months after the intake of a single dose of sodium oxybate (Xyrem®). The long‐term treatment effect correlated with attenuated brain activity in the key regions of dystonic brain network. Discussion Our case demonstrates that the novel treatment of sodium oxybate may hold promise for SD patients, especially those who have associated VT.
