Language difficulty due to brain damage is known as what?

Aphasia is the correct term for language difficulty resulting from brain damage. It refers to a communication disorder that affects a person's ability to process and use language, which may include struggles with speaking, understanding, reading, or writing. This impairment can occur after brain injuries such as strokes, head trauma, or neurological diseases that impact specific areas of the brain responsible for language functions, particularly those in the left hemisphere.

In contrast, dyslexia primarily involves difficulties with reading and language processing, but it is not solely caused by brain damage; rather, it is often characterized as a specific learning disability present from early development. Apraxia refers to motor planning difficulties that affect the execution of movements, typically not specifically tied to language, while synesthesia is a condition where stimulation of one sense leads to automatic experiences in another, which does not relate to language impairment. Thus, aphasia is the only term that directly addresses language difficulties due to brain damage.
