Global aphasia occurs due to a lesion in the perisylvian cortex, including Broca's and Wernike's areas.[1]
Global aphasia is a severe form of nonfluent aphasia, caused by damage to the left side of the brain, that affects[1] receptive and expressive language skills (needed for both written and oral language) as well as auditory and visual comprehension.[2] Acquired impairments of communicative abilities are present across all language modalities, impacting language production, comprehension, and repetition.[3][1] Patients with global aphasia may be able to verbalize a few short utterances and use non-word neologisms,[4] but their overall production ability is limited.[1] Their ability to repeat words, utterances, or phrases is also affected.[1] Due to the preservation of the right hemisphere, an individual with global aphasia may still be able to express themselves through facial expressions, gestures, and intonation.[3][5][6] This type of aphasia often results from a large lesion of the left perisylvian cortex. The lesion is caused by an occlusion of the left middle cerebral artery[4][7] and is associated with damage to Broca's area, Wernicke's area, and insular regions which are associated with aspects of language.[8][9]
