Transient Anarthria in a Patient With Non-Dominant Hemispheric Lesion: A Case Report

Anarthria is a complete loss of speech. It usually results from lesions in bilateral neural substrates that control articulation. Recently, lateralized cortical control of speech articulation in the dominant hemisphere has been reported. However, anarthria by non-dominant hemispheric lesion has not been reported yet. Here we report a rare case of transient anarthria caused by right hemispheric infarction after brain surgery in a right-handed patient. This report suggests that anarthria could be caused by a lesion not related to language lateralization. This report is expected to contribute to studies on neural correlates of anarthria lesions.
