| Definition |
Aphasia related to clinical patient characteristics, resulting from a subcortical lesion, as in the thalamus, basal ganglia, or afferent tracts to the auditory speech areas. Left thalamic hemorrhage is the most common cause of subcortical aphasia, which is associated with fluctuating language performance in which naming is impaired, speech is fluent with many paraphasias, and repetition is normal. Left basal ganglia lesions, if they are large, may produce a language impairment that resembles global aphasia.
Aphasia characterized by fluctuating language performance in which naming is impaired, speech is fluent with many paraphasias, and repetition is normal.

| Context |
It appeared that right-hemisphere language representation in crossed aphasics mirrors that which is normally present in the language-dominant left hemisphere. Cappa et al. (1983) have investigated the thorny problem of subcortical aphasia that had been discussed earlier in the literature by McFarling, Rothi and Heilmann (1982) for thalamic lesions and by Naeser et al. (1982) for putaminal lesions. In Cappa’s paper there is extensive reference to work on aphasia associated with lesions in the putamen, the caudate nucleus and the anterior limb of the internal capsule.
