Broca’s Aphasia is A nonfluent (expressive) aphasia characterized by slow, halting speech with agrammatism (telegraphic, simplified sentence structure) and relatively preserved auditory comprehension. It typically results from a lesion in the dominant frontal lobe (inferior frontal gyrus), distinguishing it from fluent aphasias like Wernicke’s (where speech is fluent but lacks meaning).
