Global aphasia is a subtype of nonfluent aphasia.
Natural History, Prognostic Factors, and Outcomes
Incidence studies suggest that global aphasia may be one of the most common aphasia types (Peach 2001). Most individuals with global aphasia present with a combination of aphasia, apraxia of speech, and hemiparesis contralateral to the side of lesion, consistent with large lesions of the language-dominant hemisphere. There are cases, however, in which there is no motor involvement and primary motor areas are spared (Bang et al. 2004; Hanlon et al. 1999).
