A young man develops nonfluent, effortful speech with dysarthria. He is able to understand speech. He fails to repeat the sentence. What would you do next?

The key is H. MRI Frontal lobe. (Brocas area). [Production (Broca's) dysphasia/aphasia - lesions are located in the left pre-central areas. This is a non-fluent or expressive aphasia since there are deficits in speech production, prosody and syntactic comprehension. Patients will typically exhibit slow and halting speech but with good semantic content. Comprehension is usually good. Unlike Wernicke's aphasia, Broca's patients are aware of their language difficulties. Prosody is the study of the meter of verse. Here it means the rhythm of speech. Sensory (Wernicke's) dysphasia/aphasia - lesions are located in the left posterior perisylvian region and primary symptoms are general comprehension deficits, word retrieval deficits and semantic paraphasias. Lesions in this area damage the semantic content of language while leaving the language production function intact. The consequence is a fluent or receptive aphasia in which speech is fluent but lacking in content. Patients lack awareness of their speech difficulties. Semantics is the meaning of words. Semantic paraphrasia is the substitution of a semantically related but incorrect word].
