[Kinesthetic aphasia associated with a pseudothalamic syndrome (author's transl)].

Kinesthetic aphasia, as described by Luria, was evoked in a case of aphasia associated with a "pseudothalamic syndrome" of partial superficial Sylvian infarction. A neurolinguistic study of oral utterances enabled qualitative and quantitative analysis of the errors: the disorder is characterized by the high incidence of articulation substitutions. A comparative study differentiated such disorders of oral expression from other aphasic disorders of expression (arthric disorders and phonemic jargon). Kinesthetic aphasia is distinguished by this clinical specificity and by the site of the lesion in the anterior parietal region of the dominant hemisphere.
