Which type of aphasia affects all forms of communication, including speaking, understanding, reading, and writing?

Global aphasia is characterized by a profound impairment in all aspects of communication. Individuals with global aphasia experience significant difficulties in speaking, understanding, reading, and writing. This condition often arises from extensive damage to the language centers of the brain, typically resulting from a large stroke affecting areas such as Broca's area and Wernicke's area simultaneously.

Since global aphasia encompasses deficits in both expressive and receptive language, it results in an inability to effectively communicate through verbal or written means. Therefore, individuals may struggle to form coherent sentences, comprehend spoken or written language, and engage in meaningful conversations. Understanding this type of aphasia is crucial for rehabilitation strategies, as it necessitates comprehensive support and targeted therapy approaches to improve communication abilities across all domains.

Expressive aphasia mainly impacts a person's ability to speak and express themselves while often allowing for relatively good understanding and the capacity to read and write, albeit with challenges. Receptive aphasia predominantly affects comprehension, leaving speech production relatively unaffected. Transitional aphasia, while not commonly recognized as a distinct type, generally refers to a stage of language recovery rather than a specific form of aphasia itself. Thus,
