Which disorder is a language disorder that can involve deficits in understanding and producing language?

• A. Aphasia
• B. Dysarthria
• C. AOS
• D. Cluttering

Answer: (A)

Language involves both understanding and expressing ideas. Aphasia is a condition caused by brain damage (often in the left hemisphere) that can impair both comprehension and the ability to produce language. People with aphasia may struggle to understand spoken language, find the right words, form grammatically correct sentences, or repeat phrases, even when their memory and intelligence are intact.

In contrast, the other conditions are motor-related or fluency issues rather than true language disorders: dysarthria affects the physical execution of speech (articulation, voice, resonance) with language content typically preserved; apraxia of speech involves planning and sequencing movements for speech but not a primary language deficit; cluttering centers on rapid, disorganized speech and fluency problems rather than understanding and producing language.

So, the term that best fits a language disorder with potential deficits in both understanding and producing language is aphasia.
