What common speech disorder might be observed in adults after a stroke?

Aphasia is a common speech disorder that can occur in adults following a stroke. This condition affects the ability to communicate effectively, impacting various aspects of language use, including speaking, understanding, reading, and writing. After a stroke, brain damage may disrupt the areas responsible for processing and producing language, which can lead to varying degrees of aphasia. Individuals with aphasia might have difficulty finding the right words, constructing sentences, or comprehending spoken or written language, depending on the location and extent of the brain injury.

In contrast, dyslexia primarily relates to difficulties in reading and is not typically caused by strokes. Stuttering is a fluency disorder that generally develops early in childhood rather than as a result of stroke, and articulation disorders involve difficulties in the physical production of speech sounds, often unrelated to the language processes affected by stroke. Thus, aphasia is distinctly linked to the language deficits that can follow a stroke, making it the correct answer in this context.
