Sensory aprosodia with left hemiparesis from subcortical infarction. Right hemisphere analogue of sensory-type aphasia with right hemiparesis?
G. I. Wolfe and E. D. Ross
We report a case of sensory aprosodia with left hemiparesis following an
ischemic infarction of the right thalamus and posterior limb of the
internal capsule. Bedside evaluation, confirmed by special quantitative
tests, demonstrated normal spontaneous affective prosody and gesturing with
marked impairment of affective repetition and comprehension of affective
prosody and gestures. A left hemiparesis with sensory loss was also
present. This combination of deficits appears to represent the right-side
analog to the unusual syndrome of Wernicke-type aphasia with right
hemiparesis occasionally observed following left subcortical injury, thus
providing further support for the hypothesis that the functional-anatomic
organization of affective language in the right hemisphere mirrors that of
propositional language in the left.
