Subcortical aphasia: a specific clinical picture?

100 aphasic patients were examined with a scorable aphasia battery looking at the frequency of various aphasia types and the possible specificity of clinical pictures in deep-seated lesions. One month after onset, "atypical" aphasiological syndromes proved to be rare and to have the same frequency in patients with cortico-subcortical or capsulostriatal deep-seated lesions. In the latter condition, no specific clinical syndrome was brought out, although verbal comprehension disorders were usually less severe than in cortico-subcortical lesions.

Assessment of hemispheric dominance for language in crossed aphasia by two atraumatic methods.

In a right handed patient with crossed aphasia, two atraumatic techniques (regional cerebral blood flow measurements during the performance of a linguistic task and dichotic listening test) were used to assess language lateralization. The prominence of rCBF activation patterns in the right hemisphere and the presence of a clear-cut right ear extinction on the dichotic listening test provide evidence that, is this case, the right hemisphere was dominant for language.
