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.

Famous quotes containing the word global:
“However global I strove to become in my thinking over the past twenty years, my sons kept me rooted to an utterly pedestrian view, intimately involved with the most inspiring and fractious passages in human development. However unconsciously by now, motherhood informs every thought I have, influencing everything I do. More than any other part of my life, being a mother taught me what it means to be human.”
—Mary Kay Blakely (20th century)
