Which communication diagnosis is most likely to require improvement in auditory language comprehension?

Wernicke's aphasia is characterized by significant impairments in auditory language comprehension. Individuals with this condition often produce fluent speech but lack meaningful content and demonstrate difficulty understanding spoken language. Their ability to grasp the meaning of words and sentences is compromised, which distinguishes this form of aphasia from others like Broca's aphasia, where comprehension is typically much better than expressive language. Thus, improvement in auditory language comprehension is a key focus for individuals diagnosed with Wernicke's aphasia, making it the most likely choice requiring such improvement.
