AbstractAbstract PDF

We describe a 43-year-old housewife who presented with dysarthria suddenly because her masseter muscles contracted bilaterally, when she was speaking. Brain MRI showed focal signal change on midbrain. Jaw dystonia induced by speaking is very rare and we chose an anticholinergic medication, rather than botulinumtoxin injection. Her condition was markedly improved after medication. We suspected that her symptoms were related with focal lesion, so she had secondary jaw dystonia induced by speaking.
