Abstract:
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.

Language formation and comprehension take place in the dominant hemisphere. The dominant hemisphere is responsible for understanding the meaning of spoken, written, or sign language, as well as the ability to communicate. For most people, the left hemisphere is the dominant one. The right hemisphere, then, gives tone and emotional context to the...
