RESUMO
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.
RESUMO
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.

The extent of recovery from aphasia following ischemic stroke has been evaluated by a quantitative method. The greatest improvement was observed during the first 3 months following onset. The rate of recovery was similar for expression and for comprehension, but comprehension was usually less disturbed than expression. Final prognosis depends on the type of aphasia (the poorest prognosis was found for total or global aphasia) and on the severity of the initial insult.

Two patients suffering from a left thalamus infarct were studied over a long period. The precise location of the lesion has been demonstrated by the C.T. scan. In spite of the absence of any cortical lesion, both presented with aphasia and other neuropsychological disorders (left-right confusion, dyscalculia and possible finger agnosia). Their speech disorders although different, had several features in common. The observations were compared with the other cases reported in the literature.
