Short Description
Global aphasia is an aphasia type in which there are no functional verbal comprehension or expression and no use of gestures to represent language.
Categorization
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).
In general, the prognosis for recovery of premorbid language skills is poor in individuals with global aphasia. This is not to say, however, that individuals with global aphasia do not show meaningful improvement over time. In consecutive studies of patients...
