Global aphasia
Global Aphasia
Global aphasia (pronounced: /ˈɡloʊbəl əˈfeɪʒə/) is a severe form of aphasia that impairs all language abilities, including speaking, understanding spoken language, reading, and writing.
Etymology
The term "global aphasia" is derived from the Greek word "aphatos" (meaning speechless) and the Latin word "globus" (meaning sphere or whole). It refers to the widespread damage to the language areas of the brain, resulting in a comprehensive loss of language skills.
Symptoms
Individuals with global aphasia have significant difficulty with both expressive and receptive language. They may produce few recognizable words and understand little or no spoken language. Reading and writing abilities are also severely impaired.
Causes
Global aphasia is typically caused by a stroke that damages extensive portions of the brain's left hemisphere, particularly the Broca's area, Wernicke's area, and the arcuate fasciculus. Other causes may include brain tumors, traumatic brain injury, and brain infections.
Treatment
Treatment for global aphasia typically involves intensive speech therapy and occupational therapy. The goal is to improve the individual's ability to communicate by restoring as much language function as possible and teaching alternative or supplementary communication methods.
