What is the primary indication of global aphasia?

Global aphasia is characterized primarily by difficulty in understanding or communicating language. This condition results from extensive damage to the areas of the brain responsible for language processing, particularly Broca's and Wernicke's areas, leading to significant impairment in both verbal expression and comprehension. Individuals with global aphasia may struggle to speak coherently, find it hard to understand spoken language, and have limited ability to read or write.

While other options might seem relevant to various neurological conditions, they do not accurately define global aphasia. For instance, inability to move parts of the body is more indicative of motor or mobility issues, sudden memory loss pertains to cognitive functions not specifically related to language, and loss of motor skills is associated with physical disabilities rather than linguistic capabilities. Thus, the primary indication that sets global aphasia apart is the profound difficulty in both understanding and producing language.
