Background:
Acquired neurogenic stuttering has been considered a fairly uncommon clinical occurrence; speech-activated myoclonus is a rare entity that can mimic stuttering and is caused by a wide array of etiologies.
Case report:
Here we report a patient with myoclonus-dystonia syndrome (MDS), due to an identified disease-causing mutation, who displayed speech-activated myoclonus mimicking stuttering.
Discussion:
In MDS, myoclonus has only infrequently been reported to affect speech. This case further expands the spectrum of conditions causing the rare clinical phenomenon of speech-activated myoclonus.
