Non-fluent Good Good Var. The peri-sylvian aphasias Structures around the sylvian fissure mediate auditory language repetition. Damage to any of these regions impairs language repetition, the hallmark of the perisylvian aphasias. Broca's aphasia Characterized by non-fluent speech, poor repetition and relatively spared comprehension. Lesions are in Broca's area and adjacent cortex.
Lesions are in Wernicke's area.
Conduction aphasia Fluent speech, spared comprehension, and poor repetition. Lesions may disconnect Wernicke's from Broca's area. Global aphasia Non-fluent speech, poor repetition and poor comprehension. The entire perisylvian cortex is involved. The transcortical aphasias These are characterized by intact repetition.
