A French accent after corpus callosum infarct

Hall Da, Anderson CA, Filley Cm et al. Neurology2003; 1551.

A patient with a midcallosal lesion (English) developed a foreign accent syndrome that resembled a native French speaker after this infarct. There was altered intonation, stresses and pauses. The problem remained six months later. The authors attribute this to the involvement of the CC in linguistic and affective prosody. They believe the lesion interrupted bihemispheric networks subserving prosody.

Comment-- an unappreciated callosal syndrome, not in most textbooks.
