Abstract

Aphasia therapy, while demonstrably successful, has been limited by its primary focus on language, with relatively less attention paid to nonlinguistic factors (cognitive, affective, praxic) that play a major role in recovery from aphasia. Neuroscientific studies of the past 15–20 years have opened a breach in the wall of traditional clinico-anatomical teachings on aphasia. It is not an exaggeration to talk of a paradigm shift. The term “neural multifunctionality” denotes a complex web of neural networks supporting both linguistic and nonlinguistic functions in constant and dynamic interaction, creating language as we know it and contributing to recovery from aphasia following brain damage. This paper reviews scientific underpinnings of neural multifunctionality and suggests ways in which this new approach to understanding the neural basis of language can lead to meaningful, practical steps for improvements in aphasia therapy.
