Global aphasia impairs all aspects of language. Patients suffering from global aphasia experience less
recovery than any other aphasia category. Language therapy for individuals with global aphasia can be
costly. Moreover, efficacy of language therapy is not yet proven for this aphasia type. Specific
rehabilitation for global aphasia has evolved from experience and literature and fulfils two purposes:
1. Support the capacities likely to improve with natural recovery, primarily the capacity to make
categorical and associational semantic discriminations;
2. Be sufficiently easy that most severe, acute global aphasic adults could comprehend the nature and
purpose of the tasks. (Alexander & Loverso 1991).
