title: Acquired capsular/striatal aphasia in childhood.
abstract: We studied a case of language loss caused by an acquired vascular lesion in the putamen, anterior limb of the internal capsule, and lateral aspect of the head of the caudate nucleus in a 7-year-old right-handed girl. Acute right-sided hemiplegia, mutism, oral apraxia, and disturbance in language comprehension but no dysarthria were present. During recovery, a nonfluent aphasia with anomia was evident. After six months, only mild hemiparesis and minor spelling difficulties persisted. We compared this patient with an 11-year-old right-handed girl with right-sided hemiparesis and dysarthria but no language loss following a lesion in the globus pallidus, a portion of the posterior limb of the internal capsule, and the body of the caudate. The presence of a language disturbance in the first but not the second patient was attributed to the difference in lesion location. The symptoms and lesions were similar to those in recent reports of adult patients. To our knowledge, this is the first report of these findings in a child with a left-hemisphere lesion.
