Global Aphasia

Global aphasia is a type of aphasia that is commonly associated with a large lesion in the perisylvian area of the frontal, temporal and parietal lobes of the brain causing an almost total reduction of all aspects of spoken and written language. It involves a "left side blowout" which includes Broca's area, Wernicke's area and the Arcuate fasciculus. It can also be seen in the initial stages of large left middle cerebral artery injuries that may progressively improve to become Expressive aphasia.

Global aphasia has been cited as among the most common type of aphasia in patients referred for speech rehabilitation therapy.
