[Role of the thalamus in subcortical aphasias].
27 cases of patients who presented language disorders of aphasic nature consecutive to a strictly subcortical lesion of vascular origin are reported. From a topographic point of view, the population is divided into 3 groups: thalamic lesions (15 cases), striatal lesions (9 cases), isolated lesions of the white matter (3 cases). The results of the neurolinguistic analysis of the aphasia show a great symptomatological variety. Nevertheless, in spite of this apparent diversity, certain semiologic elements appear to be common to all of the observed linguistic profiles, no matter where the lesion is: hypophonia, non fluent speech, verbal paraphasias, normal repetition, comprehension generally good. A discussion is proposed as to the specific part which certain structures, notably the thalamus, might play in the origin of these various disturbances.
