[New approaches in speech therapy].

Following a brief introduction of the neurological basis and the localization of aphasias, we discuss approaches to language therapy which are based on linguistic theories. We first sketch principles of language-based therapy. Then we introduce communicative aphasia treatment and explain aspects under which the latter represents an extension of the language-based approach. In order to provide neurological arguments in favour of communicative therapy, we discuss the language theory of Hughlings Jackson. Finally, we give examples for communicative therapy paradigms, for some of which implementation in specific computer training programs is available.
