Global Aphasia is a severe form of aphasia that affects almost all language abilities. It is usually caused by extensive damage to the language areas of the brain, including both Broca's area and Wernicke's area.
Causes
Global aphasia is most commonly caused by a stroke that damages large portions of the left hemisphere of the brain. Other causes can include brain tumors, traumatic brain injury, and infections that affect the brain.
Symptoms
People with global aphasia have severe language difficulties and may be unable to speak, understand spoken language, read, or write. They may be able to produce a few words or phrases, but their speech is often limited to the repetition of the same words or phrases. They may also have difficulty understanding spoken language and may not be able to follow simple instructions.
Diagnosis
The diagnosis of global aphasia is usually made by a speech-language pathologist after a thorough evaluation of the person's language abilities. This evaluation may include tests of the person's ability to speak, understand spoken language, read, and write.
Treatment
Treatment for global aphasia typically involves speech therapy to help the person improve their language abilities. This may include exercises to improve speech production, comprehension, reading, and writing skills. In some cases, assistive technology may be used to help the person communicate.
Prognosis
The prognosis for global aphasia varies depending on the extent of the brain damage and the person's age and overall health. Some people may make significant improvements with therapy, while others may continue to have severe language difficulties.
