This work has nevertheless rightfully raised the question of the role of dopamine and the subcortical structures in cognition and language. To our knowledge, the new more specific dopamine agonists have not been studied in the “indication” of aphasia, although their impact on language, and even their beneficial effect on other cognitive functions, has been demonstrated.

In the field of language pharmacology, the results of ongoing studies conducted in patients with semantic dementia should be most informative since the principle evaluation criteria must necessarily lie in the field of language and its significance.
